This Quarterly Report on Form 10-Q contains forward-looking statements that involve substantial risks and uncertainties. All statements other than statements of historical facts contained in this Quarterly Report on Form 10-Q, including statements regarding future events or our future results of operations, financial condition, business, strategies, financial needs, and the plans and objectives of management, are forward-looking statements. In some cases you can identify forward-looking statements because they contain words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “likely,” “plan,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would,” or similar expressions and the negatives of those terms. Forward-looking statements are based on information available to our management as of the date of this report and our management's good faith belief as of such date with respect to future events and are subject to a number of risks, uncertainties, and assumptions that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:

You should not place undue reliance on our forward-looking statements and you should not rely on forward-looking statements as predictions of future events. The results, events, and circumstances reflected in the forward-looking statements may not be achieved or occur, and actual results, events, or circumstances could differ materially from those described in the forward-looking statements. The forward-looking statements made in this Quarterly Report on Form 10-Q speak only as of the date of this report. We undertake no obligation to update any forward-looking statements made in this report to reflect events or circumstances after the date of this report or to reflect new information or the occurrence of unanticipated events, except as required by law. If we update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

Avalara, Inc. (the “Company”) provides software solutions that help businesses of all types and sizes comply with tax requirements for transactions worldwide. The Company offers a broad and growing suite of compliance solutions for transaction taxes, such as sales and use tax, value-added tax (“VAT”), fuel excise tax, beverage alcohol, cross-border taxes (including tariffs and duties), lodging tax, and communications tax. These solutions enable customers to automate the process of determining taxability, identifying applicable tax rates, determining and collecting taxes, preparing and filing returns, remitting taxes, maintaining tax records, and managing compliance documents. The Company, a Washington corporation, was originally incorporated in 1999 and is headquartered in Seattle, Washington.

The Company has wholly owned subsidiaries in Brazil, Canada, Europe, and India that provide business development, software development, and support services.

The accompanying consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes for the year ended December 31, 2019, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 Annual Report”) filed with the Securities and Exchange Commission (the “SEC”) on February 28, 2020. The accompanying interim consolidated balance sheet as of ~~June~~September 30, 2020, the consolidated interim statements of operations for the three and ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, the consolidated statements of comprehensive loss for the three and ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, and the consolidated statements of cash flows for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, are unaudited. The unaudited interim consolidated financial statements have been prepared on a basis consistent with that used to prepare the audited annual consolidated financial statements and include, in the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair presentation of the consolidated financial statements. The operating results for the three and ~~six~~nine months ended ~~June~~September 30, 2020, respectively, are not necessarily indicative of the results expected for the full year ending December 31, 2020.

In preparing the 2019 annual consolidated financial statements, the Company discovered an immaterial error in recording deferred sales commissions for the first three quarters of 2019 impacting its previously reported quarterly financial results. The correction to sales commission expense resulted in an increase in sales and marketing expenses and accumulated deficit of ~~$1.1~~$0.9 million and ~~$2.2~~$3.1 million for three and ~~six~~nine months ended ~~June~~September 30, 2019, respectively. The correction resulted in an increase in net loss per share of ~~$0.02~~$0.01 and ~~$0.03~~$0.05 for the three and ~~six~~nine months ended ~~June~~September 30, 2019, respectively. The restatement of these prior period corrected amounts is presented in the accompanying unaudited consolidated statements of operations for the three and ~~six~~nine months ended ~~June~~September 30, 2019, the consolidated statements of comprehensive loss for the three and ~~six~~nine months ended ~~June~~September 30, 2019, and the consolidated statement of cash flows for the ~~six~~nine months ended ~~June~~September 30, 2019.

Avalara adopted the new lease accounting standard as of January 1, 2019 in the 2019 Annual Report. Due to the timing of adoption, the Company’s 2019 interim financial statements did not reflect the new lease accounting standard. As a result, the presentation of cash flows from operating activities presented in the accompanying unaudited consolidated statement of cash flows for the ~~six~~nine months ended ~~June~~September 30, 2019 include adjustments for the adoption of the new lease accounting standard. The adjustments do not impact previously reported net cash used in operating activities.

The accompanying consolidated financial statements include those of the Company and its subsidiaries after elimination of all intercompany accounts and transactions.

The Company operates its business as 1 operating segment. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker, the Company’s Chief Executive Officer, in deciding how to allocate resources and assess performance. The Company’s chief operating decision maker allocates resources and assesses performance based upon discrete financial information at the consolidated level.

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates and judgments related to revenue are described below in the Revenue Recognition Accounting Policy. Significant estimates impacting expenses include: expected credit losses associated with the allowance for doubtful accounts; the measurement of fair values of stock-based compensation award grants; the expected earnout obligations in connection with acquisitions; the expected term of the customer relationship for capitalized contract cost amortization; the valuation of acquired intangible assets; and the valuation of the fair value of reporting units for analyzing goodwill. Actual results could materially differ from those estimates.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2: Inputs are quoted prices for similar assets and liabilities in active markets or quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

Level 3: Inputs are unobservable inputs based on the Company’s assumptions and valuation techniques used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation.

The Company’s assessment of the significance of an input to the fair value measurement requires judgment, which may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The carrying amounts reported in the consolidated financial statements approximate the fair value for cash equivalents, trade accounts receivable, trade payables, and accrued expenses, due to their short-term nature.

The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. An impairment is recognized in the event the carrying value of such assets is not recoverable. If the carrying value is not recoverable, the fair value is determined, and an impairment is recognized for the amount by which the carrying value exceeds the fair value. An impairment of the Company’s operating lease right-of-use assets and property and equipment of $0.8 million was recorded in the third quarter of 2020 (see Note 3). The impairment charge is recorded in general and administrative expenses in the consolidated statements of operations for the three and nine months ended September 30, 2020. NaN impairment of long-lived assets occurred ~~in the six months ended June 30, 2020 or~~ for the year ended December 31, 2019.

Beginning August 1, 2019, the Company established a self-insured healthcare plan for eligible U.S. employees. Under the plan, the Company pays healthcare claims and fees to the plan administrator. Total claim payments are limited by stop-loss insurance policies. As there generally is a lag between the time a claim is incurred by a participant and the time the claim is submitted for payment, the Company has recorded a self-insurance reserve for estimated outstanding claims within accrued expenses in the consolidated balance sheets.

The Company’s deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and income tax basis of assets and liabilities and are measured using the tax rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. The Company assesses its income tax positions and records tax benefits or expense based upon management’s evaluation of the facts, circumstances, and information available at the reporting date.

The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current period and deferred tax liabilities and assets for the future tax consequence of events that have been recognized in an entity’s financial statements or tax returns. The Company will recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Judgement is required in assessing the future tax consequences of events that have been recognized in the Company’s consolidated financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact the consolidated financial statements.

The Company accounts for stock-based compensation by calculating the fair value of each option, restricted stock unit (“RSU”), or purchase right issued under the Company’s 2018 Employee Stock Purchase Plan (“ESPP”) at the date of grant. The fair value of stock options and purchase rights issued under the ESPP is estimated by applying the Black-Scholes option-pricing model. This model uses the fair value of the Company’s underlying common stock at the measurement date, the expected or contractual term of the option or purchase right, the expected volatility of its common stock, risk-free interest rate, and expected dividend yield of its common stock. The fair value of an RSU is determined using the fair value of the Company’s underlying common stock on the date of grant. The Company accounts for forfeitures as they occur.

The Company primarily generates revenue from fees paid for subscriptions to tax compliance solutions and fees paid for services performed in preparing and filing tax returns on behalf of its customers. Amounts that have been invoiced are recorded in trade accounts receivable and deferred revenue, contract liabilities, or revenue, depending upon whether the revenue recognition criteria have been met. Revenue is recognized once the customer is provisioned and services are provided in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. Beginning January 1, 2019, the Company’s revenue recognition policy follows guidance from ASC 606, Revenue from Contracts with Customers.

The Company determines revenue recognition through the following five-step framework:

The Company identifies performance obligations in its contracts with customers, which primarily include subscription services and professional services. The transaction price is determined based on the amount which the Company expects to be entitled to in exchange for providing the promised services to the customer. The transaction price in the contract is allocated to each distinct performance obligation on a relative standalone selling price basis. Revenue is recognized when performance obligations are satisfied.

Contract payment terms are typically net 30 days. Collectability is assessed based on a number of factors including collection history and creditworthiness of the customer, and the Company may mitigate exposure to credit risk by requiring payments in advance. If collectability of substantially all consideration to which the Company is entitled under the contract is determined to be not probable, revenue is not recorded until collectability becomes probable at a later date.

Revenue is recorded based on the transaction price excluding amounts collected on behalf of third parties, such as sales taxes collected and remitted to governmental authorities.

Subscription and returns revenue primarily consist of contractually agreed upon fees paid for using the Company’s cloud-based solutions, which include tax determination and compliance management services, and fees paid for preparing and filing transaction tax returns on behalf of customers. Under the Company’s subscription agreements, customers select a price plan that includes an allotted maximum number of transactions over the subscription term. Unused transactions are not carried over to the customer’s next subscription term, and customers are not entitled to refunds of fees paid or relief from fees due in the event they do not use the allotted number of transactions. If customers exceed the maximum transaction level within their price plan, the Company will generally upgrade the customer to a higher transaction price plan or, in some cases, charge overage fees on a per transaction basis.

The Company’s subscription arrangements do not provide the customer with the right to take possession of the software supporting the cloud-based application services. The Company’s standard subscription contracts are non-cancelable except where contract terms provide rights to cancel in the first 60 days of the contract term. Cancellations under the Company’s standard subscription contracts are not material, and do not have a significant impact on revenue recognized. Tax returns processing services include collection of tax data and amounts, preparation of compliance forms, and submission to taxing authorities. Returns processing services are primarily charged on a subscription basis for an allotted number of returns to process within a given time period.

Revenue is recognized ratably over the contractual term of the arrangement, beginning on the date that the service is made available to the customer. The Company invoices its subscription customers for the initial term at contract signing and at each subscription renewal. Initial terms generally range from 12 to 18 months, and renewal periods are typically one year. Amounts that are contractually billable and have been invoiced, or which have been collected as cash, are initially recorded as deferred revenue or contract liabilities. While most of the Company’s customers are invoiced once at the beginning of the term, a portion of customers are invoiced semi-annually, quarterly, or monthly.

Included in the total subscription fee for cloud-based solutions are non-refundable upfront fees that are typically charged to new customers. These fees are associated with work performed to set up a customer with the Company’s services, and do not represent a distinct good or service. Instead, the fees are included within the transaction price and allocated to the remaining performance obligations in the contract. The Company recognizes revenue for these fees in accordance with the revenue recognition for those performance obligations.

Also included in subscription and returns revenue is interest income on funds held for customers. The Company uses trust accounts at FDIC-insured institutions to provide tax remittance services to customers and collect funds from customers in advance of remittance to tax authorities. After collection and prior to remittance, the Company earns interest on these funds.

The Company invoices for professional service arrangements on a fixed fee, milestone, or time and materials basis. Professional services revenue includes fees from providing tax analysis, configurations, registrations, data migrations, integration, training, and other support services. The transaction price allocated to professional services performance obligations is recognized as revenue as services are performed or upon completion of work.

The Company’s contracts with customers often include obligations to provide multiple services to a customer. Determining whether services are considered distinct performance obligations that should be accounted for separately from one another requires judgment. Subscription services and professional services are both distinct performance obligations that are accounted for separately.

Judgment is required to determine the standalone selling price (“SSP”) for each distinct performance obligation. The Company allocates revenue to each performance obligation based on the relative SSP. The Company determines SSP for performance obligations based on overall pricing objectives, which take into consideration observable prices, market conditions and entity-specific factors. This includes a review of historical data related to the services being sold and customer demographics. The Company uses a range of amounts to estimate SSP for performance obligations. There is typically more than one SSP for individual services due to the stratification of those services by information, such as size and type of customer.

The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. The Company has determined that certain costs related to employee sales incentive programs (sales commissions) and partner commission programs represent incremental costs of obtaining a contract and therefore should be capitalized. Capitalized costs are included in deferred commissions on the consolidated balance sheets. These deferred commissions are amortized over an estimated period of benefit, generally six years. The Company determines the period of benefit by taking into consideration past experience with customers, the expected life of acquired technology that generates revenue, industry peers, and other available information. The period of benefit is generally longer than the term of the initial contract because of anticipated renewals. The Company elected to apply the practical expedient to recognize the incremental costs of obtaining a contract as an expense if the amortization period of the asset would have been one year or less.

Effective January 1, 2019, the Company’s lease accounting policy follows guidance from ASC 842, Leases. Leases arise from contracts which convey the right to control the use of identified property or equipment for a period of time in exchange for consideration. The Company’s leasing arrangements are primarily for office space used to conduct operations. The Company determines whether an arrangement is or contains a lease at the inception date, based on whether there is an identified asset and whether the Company controls the use of the identified asset throughout the period of use. Leases commence when the lessor makes the asset available for use.

Leases are classified at commencement as either operating or finance leases. As of ~~June~~September 30, 2020, all of the Company’s leases are classified as operating leases. Rent expense for operating leases is recognized on the straight-line method over the term of the agreement beginning on the lease commencement date. Operating lease costs are generally fixed payments. Lease-related costs, which are variable rather than fixed, are expensed in the period incurred. Variable lease costs consist primarily of common area maintenance and utilities costs for the Company’s office spaces that are due based on the actual costs incurred by the landlord. Lease payments that depend on an index or a rate are measured using the index or rate at the commencement date and are included in operating lease costs. Subsequent increases to lease payments due to a change in the index or rate are expensed as a variable lease cost.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, related to credit losses, which amends the current accounting guidance and requires the measurements of all expected losses based on historical experience, current conditions and reasonable and supportable forecasts. The new guidance replaces the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. The guidance in ASU No. 2016-13 is required for annual periods, including interim periods within those annual periods, beginning after December 15, 2019 for public business entities. The Company adopted this guidance on January 1, 2020. The adoption, which impacted the Company’s allowance for doubtful accounts, did not have a significant impact on the consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-15, related to implementation costs incurred in a cloud computing arrangement that is a service contract. This standard aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use-software. The guidance in ASU No. 2018-15 is required for annual reporting periods, including interim periods within those annual periods, beginning after December 15, 2019, for public business entities. The Company adopted this guidance on January 1, 2020 with prospective application, as permitted by the ASU. For the first ~~half~~nine months of 2020, ~~$1.5~~the Company capitalized $2.3 million of implementation ~~costs were capitalized and are~~costs. As of September 30, 2020, there was $2.1 million recorded in other noncurrent assets and $0.2 million recorded in prepaid expenses and other current assets on the consolidated balance ~~sheet as of~~ ~~June 30, 2020~~.sheet.

In December 2019, the FASB issued ASU No. 2019-12, which simplifies the accounting for income taxes. The guidance in ASU No. 2019-12 is required for annual reporting periods, including interim periods within those annual periods, beginning after December 15, 2020, for public business entities, with early adoption permitted. The Company will adopt this guidance on January 1, 2021. The Company is currently evaluating the impact this guidance will have on the Company’s consolidated financial statements.

The following financial assets and liabilities are measured at fair value on a recurring basis. The fair values recognized in the accompanying consolidated balance sheets and the level within the fair value hierarchy in which the fair value measurements fall is as follows (in thousands):

Earnout related to business combinations

—

Earnout liabilities recorded in connection with an acquisition accounted for as a business combination under ASC 805 are recorded at estimated fair value on a recurring basis. Business combinations are discussed in Note 5. Earnouts recorded in connection with asset acquisitions are recorded as earnout payments become known. As such, earnouts related to asset acquisitions are not included in these fair value disclosures.

Earnout liabilities are classified as Level 3 liabilities because the Company uses unobservable inputs to value them, reflecting its assessment of the assumptions market participants would use to value these liabilities. Changes in the fair value of earnout liabilities are recorded in other (income) expense, net in the consolidated statements of operations.

The Company generally estimates the fair value of earnout liabilities for business combinations using probability-weighted discounted cash flows and Monte Carlo simulations. The earnout liability associated with the 2019 acquisition of Portway International Inc. (“Portway”) is based on the achievement of specific revenue and operating metrics through January 2021. As of ~~June~~September 30, 2020, the operating metrics were achieved, but the revenue metrics are not projected to be met, which resulted in a decrease to the carrying value of the earnout liability during the ~~six~~nine months ended ~~June~~September 30, ~~2020.~~2020 . The earnout periods for the 2019 acquisitions of Compli, Inc. (“Compli”) and Indix Corporation (“Indix”) ended as of January 31, 2020 and February 6, 2020, respectively. Additional information regarding payments of earnout liabilities that occurred during the ~~six~~nine months ended ~~June~~September 30, 2020 is included in Note 5.

A reconciliation of the beginning and ending balances of recurring fair value measurements recognized in the accompanying consolidated balance sheets using significant unobservable (Level 3) inputs, is as follows (in thousands):

The Company’s non-financial assets and liabilities, which include goodwill, intangible assets, and long-lived assets, are not required to be measured at fair value on a recurring basis. ~~There~~During the first nine months of 2020, certain operating lease right-of-use assets were 0measured at fair value ~~measurements~~on a non-recurring basis. In the third quarter of 2020, operating lease right-of-use assets and associated property and equipment with a total carrying value of $1.1 million was written down to fair value of $0.3 million, resulting in a $0.8 million impairment charge in the three and nine months ended September 30, 2020.

During the third quarter of 2020, the Company vacated certain leased offices in the U.S. Management does not intend to sublease these offices. Since the Company does not expect to derive future economic benefits from the operating lease right-of-use assets, the associated carrying value was reduced to 0 in accordance with ASC 360, resulting in a $0.5 million impairment in the third quarter of 2020. The impairment charge is included in general and administrative expenses in the consolidated statements of operations.

Also, during the ~~first half~~third quarter of ~~2020.~~2020, the Company vacated its leased office in Toronto, Canada and is currently seeking a tenant to sublease. Due to declining commercial real estate markets, primarily as a result of the COVID-19 pandemic, management concluded the lease costs may not be fully recoverable by a sublease. As a result of this triggering event, the Company performed an impairment test which resulted in a $0.3 million impairment of the operating lease right-of-use asset and associated property and equipment. The impairment charge is included in general and administrative expenses in the consolidated statements of operations. The fair value of the operating lease right-of-use asset and associated property and equipment was estimated using an income approach to convert market expectations of future sublease cash inflows and outflows to a single present value, which is a Level 3 measurement. Estimated cash flows were discounted at a rate commensurate with the inherent risks associated with the assets. The discount rate applied to the estimated future cash flows for the Toronto, Canada lease was 8.0%. The income approach relies on management judgment regarding the various inputs to the undiscounted cash flow forecast.

On January 22, 2019, the Company completed the acquisition of substantially all the assets of Compli under an Asset Purchase Agreement (the “Compli Purchase”). Compli is a provider of compliance services, technology, and software to producers, distributors, and importers of beverage alcohol in the United States. The Company accounted for the Compli Purchase as a business combination. As a result of the acquisition, the Company expanded its ability to provide transaction tax solutions and content for the beverage alcohol industry.

The total consideration transferred related to this transaction was $17.1 million, consisting of $11.8 million paid in cash at closing, an additional $1.6 million of cash to be paid out after twelve months, and an earnout provision fair valued upon acquisition at $3.8 million. The earnout provision is for a one-time payment and has a maximum payout of $4.0 million based on revenue recognized by the Company from the acquired operating assets for the twelve-month period ended January 31, 2020. The earnout was originally recognized at fair value at the date of the business combination and $4.0 million was paid in the first quarter of 2020.

Estimated fair values of the assets acquired and the liabilities assumed in the Compli Purchase as of the acquisition date are provided in the following table (in thousands):

The Company utilizes different valuation approaches and methodologies to determine the fair value of acquired intangible assets. A summary of the valuation methodologies, significant assumptions, and estimated useful lives of acquired intangible assets in the Compli Purchase are provided in the below table (in thousands):

The excess of the purchase price over the net identified tangible and intangible assets of $12.8 million has been recorded as goodwill, which includes synergies expected from the combined service offerings and the value of the assembled workforce. The goodwill is expected to be deductible for tax purposes.

On February 6, 2019, the Company completed the acquisition of substantially all the assets of Indix under an Asset Purchase Agreement (the “Indix Purchase”). Indix is an artificial intelligence company providing comprehensive product descriptions for more than one billion products sold and shipped worldwide. The Company accounted for the Indix Purchase as a business combination. As a result of the acquisition, the Company intends to use the Indix artificial intelligence to maintain and expand its tax content database.

The total consideration transferred related to this transaction was $9.1 million, consisting of $5.5 million paid in cash at closing, an additional $1.4 million cash to be paid after eighteen months, and an earnout provision valued upon acquisition at $2.2 million. The earnout provision has a maximum payout of $3.0 million based on the successful transition and achievement of development milestones established in the purchase agreement. The earnout provides for interim payments based on milestones to be evaluated as follows: $0.5 million within three months of closing, $0.65 million within seven months of closing, $0.65 million within eight months of closing, and $1.2 million within 12 months of closing. The earnout was originally recognized at fair value at the date of the business combination and is adjusted to fair value quarterly (see Note 3). The first earnout milestone was achieved in the second quarter of 2019 and was paid in July 2019. The second and fourth milestones were not achieved. A portion of the third milestone was achieved and $0.03 million is recorded within current accrued earnout liabilities on the consolidated balance sheet as of ~~June~~September 30, 2020.

On July 31, 2019, the Company completed the acquisition of substantially all the assets of Portway under an Asset Purchase Agreement (the “Portway Purchase”). Portway is a provider of Harmonized System classifications and outsourced customs brokerage services. The Company accounted for the Portway Purchase as a business combination. As a result of the acquisition, the Company expanded its cross-border solutions.

The total consideration transferrable related to this transaction was $24.3 million, consisting of $13.0 million paid in cash at closing, an additional $2.0 million of cash to be paid after eighteen months with an acquisition date fair value of $1.9 million, and an earnout provision fair valued upon acquisition at $9.4 million. The earnout is payable in the Company’s common stock no later than February 2021. The maximum number of shares of common stock that could be earned and transferred to the seller is 119,090 shares, which was based on a maximum payout value of $10.0 million and a per share value of $83.97 under the terms of the Portway Purchase. The earnout is based on the achievement of specific revenue and operating metrics through January 2021, and the shares (which were issued at closing and are held in escrow) will be forfeited and cancelled if the metrics are not achieved.

The earnout is based, in part, on 2 operating metric targets with a maximum payout of $7.5 million. The remainder of the earnout is based on certain revenue targets with a maximum payout of $2.5 million. Pursuant to the Portway Purchase, the shares will be transferred to the seller when the criteria under each provision are satisfied. During the ~~first half of~~nine months ended September 30, 2020, 89,318 shares of common stock (with a $7.5 million value under the Portway Purchase) were transferred to the seller to settle both operating metric targets of the earnout. The earnout was originally recognized at fair value at the date of the business combination and is adjusted to fair value quarterly (see Note 3). The remaining earnout liability related to the revenue targets was determined to be 0 as of ~~June~~September 30, 2020.

Timing may differ between the satisfaction of performance obligations and the invoicing and collection of amounts related to contracts with customers. Liabilities are recorded for amounts that are collected in advance of the satisfaction of performance obligations. To the extent a contract exists, as defined by ASC 606, these liabilities are classified as current and non-current deferred revenue. To the extent that a contract does not exist, as defined by ASC 606 (e.g. customer agreements with non-standard termination rights), these liabilities are classified as contract liabilities. Contract liabilities are transferred to deferred revenue at the point in time when the criteria that establish the existence of a contract are met.

A summary of the activity impacting the contract liabilities during the three and ~~six~~nine months ended ~~June~~September 30, 2020 and 2019 is presented below (in thousands):

As of ~~June~~September 30, 2020, ~~$10.3~~$11.0 million of deferred commissions are expected to be amortized within the next 12 months and therefore are included in current assets on the consolidated balance sheets. The remaining amount of deferred commissions are included in noncurrent assets. There were 0 impairments of assets related to deferred commissions during the ~~six~~nine months ended ~~June~~September 30, 2020 or 2019. There were 0 assets recognized related to the costs to fulfill contracts during the ~~six~~nine months ended ~~June~~September 30, 2020 or 2019 as these costs were not material.

Contracts with customers include amounts allocated to performance obligations that will be satisfied at a later date. These amounts include additional performance obligations that are not yet recorded in the consolidated balance sheets. As of ~~June~~September 30, 2020, amounts allocated to these additional contractual obligations are ~~$40.8~~$40.4 million, of which ~~$40.4~~$40.0 million is expected to be recognized as revenue over the next 12 months with the remaining amount thereafter.

Finite-lived intangible assets are generally amortized on a straight-line basis over the remaining estimated useful life as management believes this reflects the expected benefit to be received from these assets. Finite-lived intangible assets amortization expense was ~~$1.6~~$1.5 million and ~~$3.5~~$4.9 million for the three and ~~six~~nine months ended ~~June~~September 30, 2020, respectively, and $1.8 million and ~~$3.5~~$5.3 million for the three and ~~six~~nine months ended ~~June~~September 30, 2019, respectively.

Changes in the carrying amount of goodwill for the ~~six~~nine months ended ~~June~~September 30, 2020 are summarized as follows (in thousands):

Balance—December 31, 2019	$	101,224		$	101,224
Cumulative translation adjustments		(26	)		446
Balance—June 30, 2020	$	101,198
Balance—September 30, 2020				$	101,670

Goodwill is tested for impairment annually on October 31 at the reporting unit level or whenever circumstances occur indicating goodwill might be impaired. The impairment test involves comparing the fair value of each reporting unit to its carrying value, including goodwill. Fair value reflects the price a market participant would be willing to pay in a potential sale of the reporting unit. If the fair value exceeds carrying value, the Company will conclude that 0 goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, the Company will recognize an impairment loss in an amount equal to the excess, not to exceed the carrying value. The Company has 3 reporting units for goodwill impairment testing consisting of its U.S., European, and Brazilian operations. As of ~~June~~September 30, 2020, the Brazilian reporting unit had 0 associated goodwill.

Total lease cost, net of sublease income, was ~~$3.9~~$4.1 million and ~~$7.7~~$11.8 million for the three and ~~six~~nine months ended ~~June~~September 30, 2020, respectively, and ~~$2.9~~$3.0 million and ~~$5.5~~$8.5 million for the three and ~~six~~nine months ended ~~June~~September 30, 2019, respectively. Sublease income was $0.4 million and ~~$0.8~~$1.1 million for the three and ~~six~~nine months ended ~~June~~September 30, 2020, respectively and $0.4 million and ~~$0.7~~$1.1 million for the three and ~~six~~nine months ended ~~June~~September 30, 2019, respectively. Leases that commenced in the first ~~half~~nine months of 2020 increased operating lease right-of-use assets by ~~$6.6~~$7.8 million.

An impairment of the Company’s operating lease right-of-use assets and property and equipment of $0.8 million was recorded in the third quarter of 2020 (see Note 3).

Loss contingencies may arise in connection with the ordinary conduct of the Company’s business activities. The Company considers loss contingencies on a quarterly basis and based on known facts assesses whether potential losses are considered reasonably possible, probable, and estimable. The Company establishes an accrual for loss contingencies when the loss is both probable and reasonably estimable. If the estimated loss is a range of potential outcomes and there is no better estimate within the range, management accrues the amount at the low end of the range. These accruals represent management’s estimate of probable losses and, in such cases, there may be an exposure to loss in excess of the amounts accrued. Significant judgment is required to determine both likelihood of there being a probable loss and the estimated amount of a loss. If a loss contingency is not both probable and reasonably estimable, the Company does not establish an accrual, but will evaluate other disclosure requirements and continue to monitor the matter for developments that would make the loss contingency both probable and reasonably estimable. The ultimate outcome of any litigation relating to a loss contingency is uncertain and, regardless of outcome, litigation can have an adverse impact on the Company because of defense costs, negative publicity, diversion of management resources, and other factors.

On October 22, 2018, PTP OneClick, LLC (“PTP”) filed a lawsuit against Avalara, Inc. in the United States District Court for the Eastern District of Wisconsin. The lawsuit alleges that making, using, offering to sell, and selling AvaTax, Avalara Returns, and TrustFile (the “Avalara Products”) infringe U.S. Patent No. 9,760,915 held by PTP and also alleges unspecified trade secret misappropriation, unfair competition, and breach of contract. PTP seeks judgments of willful patent infringement, willful trade secret misappropriation, unfair competition, and breach of contract. PTP requests preliminary and permanent injunctions to enjoin the Company from making, using, offering to sell, and selling the Avalara Products along with treble damages and attorneys’ fees. Based upon the Company’s review of the complaint and the specified patent, the Company believes that the Company has meritorious defenses to PTP’s claims. On November 7, 2018, the Company moved to dismiss the lawsuit and to have the patent held invalid, and also moved to transfer the matter to the United States District Court located in Seattle, Washington. On April 30, 2019, the United States District Court for the Eastern District of Wisconsin granted the Company’s motion to transfer, reserving resolution of the motion to dismiss for the United States District Court for the Western District of Washington. On October 7, 2019, the United States District Court for the Western District of Washington invalidated the patent and dismissed the patent and unfair competition claims with prejudice but did not dismiss the trade secret misappropriation or breach of contract claims. On March 5, 2020, we filed a motion for summary judgment. On May 27, 2020, the United States District Court for the Western District of Washington entered summary judgment in favor of Avalara, Inc. disposing of the remaining trade secret misappropriation and breach of contract claims. Plaintiff filed a notice of appeal but subsequently withdrew the notice. On July 7, 2020, the United States District Court for the Western District of Washington dismissed the appeal with prejudice.

In its standard subscription agreements, the Company has agreed to indemnification provisions with respect to certain matters. Further, from time to time, the Company has also assumed indemnification obligations through its acquisition activity. These indemnification provisions can create a liability to the Company if its services do not appropriately calculate taxes due to tax jurisdictions, or if the Company is delinquent in the filing of returns on behalf of its customers. Although the Company’s agreements have disclaimers of warranties that limit its liability (beyond the amounts the Company agrees to pay pursuant to its indemnification obligations and guarantees, as applicable), a court could determine that such disclaimers and limitations are unenforceable as a matter of law and hold the Company liable for certain errors. Further, in some instances the Company has negotiated agreements with specific customers or assumed agreements in connection with the Company’s acquisitions that do not limit this liability or disclaim these warranties. Except as discussed below, it is not possible to reasonably estimate the potential loss under these indemnification arrangements.

While the Company has never paid a material claim related to these indemnification provisions, the Company believes that, as of ~~June~~September 30, 2020, there is a reasonable possibility that a loss may be incurred pursuant to certain of these arrangements and estimates a range of loss of up to $2.0 million. The Company has not recorded an accrual related to these arrangements as of ~~June~~September 30, 2020 because it has not determined that a loss is probable. The ultimate outcome of these potential obligations is unknown, and it is possible that the actual losses could be higher than the estimated range.

The Company had a loan and security agreement with Silicon Valley Bank and Ally Bank that consisted of a $50.0 million revolving credit facility (the “Credit Facility”). On June 25, 2019, the Company terminated the Credit Facility.

Prior to termination of the Credit Facility, the Company was required to pay a quarterly fee of 0.50% per annum on the undrawn portion available under the revolving credit facility plus the sum of outstanding letters of credit. Under the Credit Facility, the interest rate on the revolving credit facility was based on the greater of either 4.25% or the current prime rate, plus 1.75%.

Under the Amended and Restated Articles of Incorporation, which became effective in June 2018, the Company is authorized to issue 2 classes of stock designated as common stock and preferred stock. The Company’s total authorized capital stock is 620,000,000 shares, consisting of 600,000,000 shares of common stock, $0.0001 par value per share, and 20,000,000 shares of undesignated preferred stock, $0.0001 par value per share.

In June 2019, the Company completed a follow-on public offering, in which the Company sold 4,133,984 shares of its common stock, including the full exercise of the underwriters’ option to purchase 539,215 additional shares of common stock, at a price of $69.40 per share. The Company received net proceeds of $274.7 million, after deducting underwriting discounts and commissions and before deducting offering expenses paid and payable by the Company of $1.2 million.

In August 2020, the Company completed a second follow-on public offering, in which the Company sold 4,527,558 shares of its common stock, including the full exercise of the underwriters’ option to purchase 590,551 additional shares of common stock, at a price of $127.00 per share. The Company received net proceeds of $556.3 million, after deducting underwriting discounts and commissions and before deducting offering expenses paid and payable by the Company of $0.7 million.

The Company has stock-based compensation plans that provide for the award of equity incentives, including stock options, stock awards, RSUs, and purchase rights. As of ~~June~~September 30, 2020, the Company had stock options outstanding under the 2018 Equity Incentive Plan (the “2018 Plan”) and the 2006 Equity Incentive Plan (the “2006 Plan”), had RSUs outstanding under the 2018 Plan, and had purchase rights issued under the ESPP.

In April 2018, the 2018 Plan became effective in connection with the Company’s IPO. The 2018 Plan allows the Company to grant equity incentives to employees, directors, advisors, and consultants providing services to the Company or a subsidiary. The total number of shares of common stock reserved for issuance under the 2018 Plan is equal to (1) 5,315,780 shares (excluding automatic annual share increases) plus (2) any shares subject to outstanding awards under the 2006 Plan as of June 14, 2018 that subsequently cease to be subject to such awards. The available shares automatically increase each January 1, beginning January 1, 2019, by the lesser of (i) 5% of the aggregate number of shares of common stock outstanding on December 31^st of the immediately preceding calendar year (rounded up to the nearest whole share) and (ii) an amount determined by the Company’s Board of Directors. As of ~~June~~September 30, 2020, ~~3,493,168~~3,598,779 shares were subject to outstanding awards and ~~9,111,608~~8,975,281 shares were available for issuance under the 2018 Plan. The 2018 Plan provides that on the occurrence of certain strategic events, such as a change in control in which options and RSUs are not assumed or substituted, such outstanding options and RSUs will become fully vested and exercisable or payable.

Prior to the 2018 Plan, the Company awarded stock options under the 2006 Plan. The 2006 Plan was terminated in connection with the Company’s IPO. Outstanding awards under the 2006 Plan continue to be subject to the terms and conditions of the 2006 Plan. As of ~~June~~September 30, 2020, there were ~~3,119,524~~2,797,085 shares subject to outstanding stock options under the 2006 Plan.

The Company recognized total stock-based compensation cost related to equity incentive awards as follows (in thousands):

The total intrinsic value of options exercised during the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019 was ~~$131.2~~$168.3 million and ~~$192.4~~$287.7 million, respectively.

The weighted average grant date fair value of options granted during the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019 was ~~$30.06~~$32.87 and $18.93 per share, respectively. During the ~~six~~nine months ended ~~June~~September 30, 2020, ~~963,748~~1,277,331 options vested. There were ~~2,122,011~~1,825,169 options unvested as of ~~June~~September 30, 2020.

As of ~~June~~September 30, 2020, ~~$28.8~~$26.7 million of total unrecognized compensation cost related to stock options was expected to be recognized over a weighted average period of approximately ~~2.5~~2.4 years.

All options given to participants, including employees and non-employee directors, are measured based on the grant date fair value of the awards and recognized in the consolidated statements of operations over the period during which the participant is required to perform services in exchange for the award. The vesting period is generally four years for employees and one year for non-employee directors. For the options granted during the periods presented, the fair value of options was estimated using the Black-Scholes option-pricing model with the following assumptions:

	For the Three Months Ended June 30,		For the Six Months Ended June 30,		For the Three Months Ended September 30,			For the Nine Months Ended September 30,
	2020	2019	2020	2019	2020	2019		2020	2019
Fair market value of common stock	$66.26 - 99.65	$55.10 - 72.67	$66.26 - 99.65	$39.76 - 72.67	$124.35 - 130.82		—	$66.26 - 130.82	$39.76 - 72.67
Volatility	43%	40%	43%	40%	43%		—	43%	40%
Expected term	5-6 years	5-6 years	5-6 years	5-6 years	6 years		—	5-6 years	5-6 years
Expected dividend yield	n/a	n/a	n/a	n/a	n/a		0	n/a	n/a
Risk-free interest rate	0.33% - 0.51%	1.77% - 2.49%	0.33% - 1.25%	1.77% - 2.65%	0.44% - 0.51%		—	0.33% - 1.25%	1.77% - 2.65%

The Board of Directors intends all options granted to be exercisable at a price per share not less than the per share fair market value of the Company’s common stock underlying those options on the date of grant. The fair market value per share of the Company’s common stock for purposes of determining stock-based compensation is the closing price of the Company’s common stock as reported on the applicable grant date.

Beginning in 2020, expected volatility for stock options is based on a combination of annualized daily historical volatility of the Company’s stock price and the historical and implied volatility of comparable publicly traded companies over a similar expected term. Prior to 2020, expected volatility was based only on the historical and implied volatility of comparable publicly traded companies over a similar expected term.

The expected term represents the period that the Company’s stock-based awards are expected to be outstanding. Given the Company’s relative inexperience of significant exercise activity, the expected term assumptions were determined based on application of the simplified method of expected term calculation by averaging the contractual life of option grants and the vesting period of such grants. This application, when coupled with the contractual life of ten years and average vesting term of four years for employees and one year for non-employee directors, creates an expected term of six years and five years, respectively.

The risk-free interest rate was based on the rate for a U.S. Treasury zero-coupon issue with a term that closely approximates the expected term of the option grant at the date nearest the option grant date.

The following table summarizes RSU activity for the Company’s stock-based compensation plans for the ~~six~~nine months ended ~~June~~September 30, 2020:

				Weighted					Weighted
				Average					Average
				Grant Date Fair					Grant Date Fair
	Restricted Stock Units			Value Per Share		Restricted Stock Units			Value Per Share
RSUs outstanding as of January 1, 2020		1,508,281		$	51.52		1,508,281		$	51.52

RSUs outstanding as of September 30, 2020							2,333,467		$	66.60

Stock-based compensation cost for RSUs is recognized on a straight-line basis in the consolidated statements of operations over the period during which the participant is required to perform services in exchange for the award, based on the fair value of the Company’s underlying common stock on the date of grant. The vesting period of each RSU grant is generally four years for

employees and one year for non-employee directors. As of ~~June~~September 30, 2020, ~~$126.6~~$136.8 million of total unrecognized compensation cost related to RSUs was expected to be recognized over a weighted average period of approximately ~~3.3 years~~.3.2 years.

The ESPP became effective on June 15, 2018, the first trading day of the Company’s common stock. The ESPP is intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code of 1986, as amended. Purchases are accomplished through participation in discrete offering periods. The first offering period began on June 15, 2018 and ended on January 31, 2019. Subsequent offering periods begin on August 1 and February 1 (or such other date determined by our Board of Directors or our Compensation and Leadership Development Committee).

Eligible employees can select a rate of payroll deduction for purchases under the ESPP of between 1% and 15% of their eligible compensation. The purchase price for shares of common stock purchased under the ESPP is 85% of the lesser of the fair market value of the Company’s common stock on (i) the first day of the applicable offering period or (ii) the last day of the purchase period in the applicable offering period.

The Company initially reserved 996,709 shares of common stock for sale under the ESPP. The aggregate number of shares reserved for sale under the ESPP increases automatically on each January 1, beginning January 1, 2019, by the number of shares equal to the least of (i) 1,000,000 shares of common stock, (ii) 1% of the aggregate number of shares of common stock outstanding on December 31^st of the immediately preceding calendar year (rounded up to the nearest whole share), and (iii) an amount determined by the Board of Directors. No more than an aggregate of 10,102,525 shares of common stock may be issued over the ten-year term of the ESPP. As of ~~June~~September 30, 2020, ~~1,851,268~~1,775,457 shares of common stock are reserved for sale under the ESPP.

~~There were 0 stock purchases under the ESPP during~~During the three and nine months ended ~~June 30, 2020. During the six months ended June~~September 30, 2020, ~~81,894~~75,811 and 157,705 shares of common stock were purchased under the ~~ESPP.~~ESPP, respectively.

As of ~~June~~September 30, 2020, there was approximately ~~$0.3~~$1.6 million of unrecognized stock-based compensation cost related to the ESPP that is expected to be recognized over the remaining term of the offering period that began on ~~February~~August 1, 2020 and will end on ~~July~~January 31, ~~2020.~~2021.

For the periods presented, the fair value of ESPP purchase rights was estimated using the Black-Scholes option-pricing model with the following assumptions:

	For the Three and Six Months Ended June 30,		For the Three Months Ended September 30,			For the Nine Months Ended September 30,
	2020	2019	2020		2019	2020	2019

Risk-free interest rate	1.54%	2.59%	0.11%		2.04%	0.11% to 1.54%	2.04% to 2.59%

Beginning in 2020, the expected volatility for ESPP purchase rights is based on daily historical volatility of the Company’s stock price. Prior to 2020, expected volatility was based only on the historical and implied volatility of comparable publicly traded companies over a similar expected term.

The Company calculates basic and diluted net loss per share attributable to common shareholders in conformity with the two-class method required for companies with participating securities.

The diluted net loss per share attributable to common shareholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, all common stock equivalents have been excluded from the calculation of diluted net loss per share attributable to common shareholders as their effect is antidilutive. As a result, basic and diluted net loss per common share was the same for each period presented.

The following table sets forth the computation of basic and diluted net loss per common share (in thousands, except per share amounts):

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with the consolidated financial statements and related notes that are included elsewhere in this Quarterly Report on Form 10-Q and our 2019 Annual Report. This discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors,” in Part II, Item 1A of this Quarterly Report on Form 10-Q and our 2019 Annual Report. See “Special Note Regarding Forward-Looking Statements” above.

We provide a leading suite of cloud-based solutions that help businesses of all types and sizes comply with transaction tax requirements worldwide. Our Avalara Compliance Cloud offers a broad and growing suite of compliance solutions that enable businesses to address the complexity of transaction tax compliance, process transactions in real time, produce detailed records of transaction tax determinations, and reduce errors, audit exposure, and total transaction tax compliance costs.

We derive most of our revenue from subscriptions to our solutions. Subscriptions and returns revenue accounted for 94% and 93% of our total revenue during the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, respectively. The initial term of our subscription contracts generally ranges from twelve to eighteen months, and renewal periods are typically one year in length. Subscription and returns revenue is primarily driven by the number of customers we have and the price plans they select for volumes of tax calculations, returns, and tax exemption certificates. We also derive revenue from providing professional services. During the first ~~half~~nine months of 2020, we generated approximately 94% of our revenue in North America and we are expanding our international presence to support transaction tax compliance in Europe, South America, and Asia.

Our total revenue for the three months ended ~~June~~September 30, 2020 was ~~$116.5~~$127.9 million compared to ~~$91.3~~$98.5 million for the three months ended ~~June~~September 30, 2019. Our total revenue for the ~~six~~nine months ended ~~June~~September 30, 2020 was ~~$227.9~~$355.8 million compared to ~~$176.3~~$274.8 million for the ~~six~~nine months ended ~~June~~September 30, 2019. Our net loss for the three months ended ~~June~~September 30, 2020 was ~~$10.1~~$12.7 million compared to a net loss of ~~$14.2~~$13.3 million for the three months ended ~~June~~September 30, 2019. Our net loss for the ~~six~~nine months ended ~~June~~September 30, 2020 was ~~$25.4~~$38.2 million compared to a net loss of ~~$24.6~~$37.9 million for the ~~six~~nine months ended ~~June~~September 30, 2019.

Our global operations expose us to risks associated with public health crises and pandemics, such as the ~~recent~~ novel coronavirus (“COVID-19”) pandemic. Our priority remains the health and safety of our employees and their families. Almost all of our employees are able to work offsite and most have been working from home since March ~~2020.~~2020, when the pandemic began. In some locations, where allowed by local authorities, we have ~~begun reopening~~reopened office locations for a limited number of employees. Currently, almost all of our employees are working from home and we expect these arrangements to continue for most of our workforce into 2021.

We believe our recent operating results reflect the adaptability and resiliency of our business. Despite the global economic decline that has impacted many of our customers, our total revenue continues to increase as we benefit from the accelerating growth of ecommerce driven, to a certain extent, by the COVID-19 pandemic, and from the increased benefits our software solutions bring to customers looking to reduce costs by automating tax compliance.

During the third quarter of 2020, we decided to permanently close several of our smaller offices in the U.S. and our office in Toronto, Canada. Employees assigned to those office locations will continue to work from home, including after the end of the COVID-19 pandemic. As a result of these office closures, we recorded a $0.8 million impairment charge against the impacted operating lease right-of-use assets and associated property and equipment. While not expected to be significant, we expect to incur additional expenses in the fourth quarter of 2020 related to terminating these lease obligations.

~~In the second quarter of~~nine months ended September 30, 2020, operating expenses were lower than initially ~~planned partially due to the COVID-19 pandemic.~~planned. We have temporarily reduced spending on in-person marketing events and company-wide travel ~~costs, and, to a lesser extent, we slowed the pace of hiring new employees.~~costs. These expense reductions were partially offset by one-time bonus payments to employees to assist with work from home expenses, additional spending on systems and applications that do not depend on employees being physically present in our offices, and incremental expenses incurred to prepare our offices to reopen safely.

During the nine months ended September 30, 2020, our operating cash flows were positively impacted by the deferral of U.S. employer payroll tax payments under the Coronavirus Aid, Relief and Economic Security Act (“the CARES Act”). In the second quarter of 2020, our operating cash flows were negatively impacted to the extent we experienced a slowdown in collections on accounts receivable as a result of extending longer than typical credit terms for new customers and a slowdown in payments from customers. During the third quarter of 2020, however, cash collections on accounts receivable improved and customers but this was partially offset by the deferral of U.S. employer payroll tax payments under the Coronavirus Aid, Relief and Economic Security Act (“the CARES Act”). While we are impacted by the COVID-19 pandemic and the resulting global economic decline, we currently believe that ~~our strong cash position, which was $474.4 million as of June 30, 2020, will be sufficient to meet our anticipated cash needs for at least the next 12 months.~~were granted longer credit terms generally paid amounts when due.

As the COVID-19 pandemic continues to evolve, ~~in all locations in which we operate,~~ the extent and timing of the broader impact of the pandemic on our results of operations, overall financial performance and operating cash flows remains uncertain, including the impact on our future revenue growth, the timing of resumption of normal operating expenses, and incremental expenses associated with preventative and precautionary measures that we are taking in response to the pandemic.

We regularly review several metrics to evaluate growth trends, measure our performance, formulate financial projections, and make strategic decisions. We discuss revenue and the components of operating results under the section of this report titled, “Key Components of Consolidated Statements of Operations,” and we discuss other key business metrics below.

We believe core customers is a key indicator of our market penetration, growth, and potential future revenue. The mid-market has been and remains our primary target market segment for marketing and selling our solutions. We use core customers as a metric to focus our customer count reporting on our primary target market segment. As of ~~June~~September 30, 2020 and December 31, 2019, we had approximately ~~13,300 and 11,960 core customers, respectively. Including the revised calculation, as of June 30, 2020 and December 31, 2019, we had approximately 13,560~~14,180 and 12,150 core customers, respectively. In the first ~~half~~nine months of 2020, our core customers represented more than 80% of our total revenue.

Currently, our core customer count includes only customers with unique account identifiers in our primary U.S. billing systems and does not include customers who subscribe to our solutions through our international subsidiaries and certain legacy billing systems that have not been integrated into our primary U.S. billing systems (e.g., our lodging tax compliance solution). As we increase our international operations and sales in future periods, we may add customers billed from our international subsidiaries to the core customer metric.

We also have a substantial number of customers of various sizes who do not meet the revenue threshold to be considered a core customer. Many of these customers are in the small business and self-serve segment of the marketplace, which represents strategic value and a growth opportunity for us. Customers who do not meet the revenue threshold to be considered a core customer provide us with market share and awareness, and we anticipate that some may grow into core customers.

We believe that our net revenue retention rate provides insight into our ability to retain and grow revenue from our customers, as well as their potential long-term value to us. We also believe it reflects the stability of our revenue base, which is one of our core competitive strengths. We calculate our net revenue retention rate by dividing (a) total revenue in the current quarter from any billing accounts that generated revenue during the corresponding quarter of the prior year by (b) total revenue in such corresponding quarter from those same billing accounts. This calculation includes changes for these billing accounts, such as additional solutions purchased, changes in pricing and transaction volume, and terminations, but does not reflect revenue for new billing accounts added during the one-year period. Our

Streamlined Sales Tax (SST) solution is not included in net revenue retention rate. This means that revenue expansion from existing customers adopting our SST solution is not included, while revenue contraction from customers downgrading one or more of Avalara’s other solutions in favor of SST is included.

Currently, our net revenue retention rate calculation includes only customers with unique account identifiers in our primary U.S. billing systems and does not include customers who subscribe to our solutions through our international subsidiaries or certain legacy billing systems, primarily related to past acquisitions. Our net revenue retention rate was ~~107%~~108% for the quarter ended ~~June~~September 30, 2020 and on average has been ~~110%~~108% over the last four quarters ended ~~June~~September 30, 2020.

We generate revenue from two primary sources: (1) subscription and returns; and (2) professional services. Subscription and returns revenue are driven primarily by the acquisition of customers, customer renewals, and additional service offerings purchased by existing customers. Revenue from subscriptions and returns comprised approximately 94% of our revenue for the ~~six~~nine months ended ~~June~~September 30, 2020 and 93% of our revenue for the ~~six~~nine months ended ~~June~~September 30, 2019.

Subscription and Returns Revenue. Subscription and returns revenue primarily consist of fees paid by customers to use our solutions. Subscription plan customers select a price plan that includes an allotted maximum number of transactions over the subscription term. Unused transactions are not carried over to the customer’s next subscription term, and our customers are not entitled to any refund of fees paid or relief from fees due if they do not use the allotted number of transactions. If a subscription plan customer exceeds the selected maximum transaction level, we will generally upgrade the customer to a higher tier or, in some cases, charge overage fees on a per transaction or return basis. Customers purchase tax return preparation on a subscription basis for an allotted number of returns.

Our standard subscription contracts are generally non-cancelable after the first 60 days of the contract term. Cancellations under our standard subscription contracts are not material, and do not have a significant impact on revenue recognized. We generally invoice our subscription customers for the initial term at contract signing and upon renewal. Our initial terms generally range from twelve to eighteen months, and renewal periods are typically one year. Amounts that have been invoiced are initially recorded as deferred revenue or contract liabilities. Subscription revenue is recognized on a straight-line basis over the service term of the arrangement beginning on the date that our solution is made available to the customer and ending at the expiration of the subscription term. Subscription and returns revenue also include interest income generated on funds held for customers. In order to provide tax remittance services to customers, we hold funds from customers in advance of remittance to tax authorities. These funds are held in trust accounts at FDIC-insured institutions. Prior to remittance, we earn interest on these funds.

Currently a small component of our total revenue, we offer SST services to businesses that are registered to participate in the program. We earn a fee (SST revenue) from participating state and local governments based on a percentage of the sales tax reported and paid, and as a result, we generally provide SST services at no cost to the seller.

Professional Services. We generate professional services revenue from providing tax analysis, configurations, data migrations, integration, training, and other support services. We bill for service arrangements on a fixed fee, milestone, or time and materials basis, and we recognize the transaction price allocated to professional services performance obligations as revenue as services are performed and are collectable under the terms of the associated contracts.

Cost of Revenue. Cost of revenue consists of costs related to providing the Avalara Compliance Cloud and supporting our customers and includes employee-related expenses, including salaries, benefits, bonuses, and stock-based compensation. In addition, cost of revenue includes direct costs associated with information technology, such as data center and software hosting costs, tax content maintenance, and certain services provided by third parties. Cost of revenue also includes allocated costs for certain information technology and facility expenses, along with depreciation of equipment and amortization of intangibles such as acquired technology from acquisitions. We plan to continue to significantly expand our infrastructure and personnel to support our future growth, including through acquisitions, which we expect to result in higher cost of revenue in absolute dollars.

Research and Development. Research and development expenses consist primarily of employee-related expenses for our research and development staff, including salaries, benefits, bonuses, stock-based compensation, the cost of third-party developers and other independent contractors, and the amortization of capitalized software development costs. Research and development costs, other than

software development expenses qualifying for capitalization, are expensed as incurred. Capitalized software development costs consist primarily of employee-related costs. Research and development expenses also include allocated costs for certain information technology and facility expenses.

We devote substantial resources to enhancing and maintaining the Avalara Compliance Cloud, developing new and enhancing existing solutions, conducting quality assurance testing, and improving our core technology. We expect research and development expenses to increase in absolute dollars.

Sales and Marketing. Sales and marketing expenses consist primarily of employee-related expenses for our sales and marketing staff, including salaries, benefits, bonuses, sales commissions, and stock-based compensation, integration and referral partner commissions, costs of marketing and promotional events, corporate communications, online marketing, solution marketing, and other brand-building activities. As a result of the current COVID-19 pandemic, we have suspended in-person promotional and customer events and have converted many of these activities to virtual events, which has temporarily reduced these types of marketing expenses. We expect to resume in-person marketing activities when conditions allow. Sales and marketing expenses include allocated costs for certain information technology and facility expenses, along with depreciation of equipment and amortization of intangibles such as customer databases from acquisitions.

We defer the portion of sales commissions that is considered a cost of obtaining a contract with a customer in accordance with the revenue recognition standard and amortize these deferred costs over the period of benefit, currently six years. We expense the remaining sales commissions as incurred. Sales commissions are earned when a sales order is completed. For most sales orders, deferred revenue is recorded when a sales order is invoiced, and the related revenue is recognized ratably over the subscription term. The rates at which sales commissions are earned varies depending on a variety of factors, including the nature of the sale (new, renewal, or add-on service offering), the type of service or solution sold, and the sales channel. At the beginning of each year we set group and individual sales targets for the full year. Sales commissions are generally earned based on achievement against these targets.

We defer the portion of partner commissions costs that are considered a cost of obtaining a contract with a customer in accordance with the revenue recognition standard and amortize these deferred costs over the period of benefit. The period of benefit is separately determined for each partner and is either six years or corresponds with the contract term. We expense the remaining partner commissions costs as incurred. Our partner commission expense has historically been, and will continue to be, impacted by many factors, including the proportion of new and renewal sales, the nature of the partner relationship, and the sales mix among partners during the period. In general, integration partners are paid a higher commission for the initial sale to a new customer and a lower commission for renewal sales. Additionally, we have several types of partners (e.g., integration and referral) that each earn different commission rates.

We intend to continue to invest in sales and marketing and expect spending in these areas to increase in absolute dollars as we continue to expand our business. We expect sales and marketing expenses to continue to be among the most significant components of our operating expenses.

General and Administrative. General and administrative expenses consist primarily of employee-related expenses for administrative, finance, information technology, legal, and human resources staff, including salaries, benefits, bonuses, and stock-based compensation, professional fees, insurance premiums, and other corporate expenses that are not allocated to the above expense categories.

We expect our general and administrative expenses to increase in absolute dollars as we continue to expand our operations, hire additional personnel, evaluate and integrate acquisitions, and incur costs as a public company. Specifically, we expect to continue to incur increased expenses related to accounting, tax and auditing activities, legal, insurance, SEC compliance, and internal control compliance.

Total other (income) expense, net consists of interest income on cash and cash equivalents, quarterly remeasurement of contingent consideration for acquisitions accounted for as business combinations, foreign currency gains and losses, and other nonoperating gains and losses.

The following sets forth our results of operations for the periods presented and as a percentage of our total revenue for those periods. The period-to-period comparison of financial results is not necessarily indicative of financial results to be achieved in future periods.

The comparability of periods covered by our financial statements is impacted by acquisitions. In the first quarter of 2019, we acquired substantially all the assets of Compli and Indix and in the third quarter of 2019, we acquired substantially all the assets of Portway.

Interest income decreased due to a decline in the interest rate earned on our cash and cash equivalents, partially offset by higher average cash balances during the first ~~half~~three quarters of 2020. Other income (expense), net was ~~$3.3~~$3.4 million other income for the ~~six~~nine months ended ~~June~~September 30, 2020 compared to ~~$0.4~~$0.7 million other expense for the ~~six~~nine months ended ~~June~~September 30, 2019, due primarily ~~due~~ to changes to our earnout liabilities. We estimate the fair value of earnout liabilities related to business combinations quarterly. During the nine months ended September 30, 2020, the adjustments to fair value decreased the carrying value of the earnout liability for our acquisition of Portway, resulting in other income of $2.3 million. The fair value of the Portway acquisition earnout liability decreased ~~at June 30, 2020~~ due primarily to a reduction in the revenue projections used to estimate the fair value of the earnout to reflect a decrease in anticipated cross-border transactions as a result of the economic disruption caused by the COVID-19 ~~pandemic.~~ pandemic. During the first ~~half~~three quarters of 2019, the adjustments to fair value increased the carrying value of the earnout liabilities for our Compli and Indix acquisitions, resulting in other expense of ~~$0.5~~$0.6 million.

The provision for income taxes for the ~~six~~nine months ended ~~June~~September 30, 2020 was ~~$0.6~~$0.9 million compared to a provision for income taxes of ~~$0.3~~$0.6 million for the ~~six~~nine months ended ~~June~~September 30, 2019. The increase was due primarily to additional foreign income taxes. The effective income tax rate was ~~2.2%~~2.5% for the ~~six~~nine months ended ~~June~~September 30, 2020 compared to ~~1.2%~~1.7% for the ~~six~~nine months ended ~~June~~September 30, 2019. The effective tax rate in both ~~quarters~~periods differs from the U.S. Federal statutory rate due primarily to providing a valuation allowance on deferred tax assets.

We have assessed our ability to realize our deferred tax assets and have recorded a valuation allowance against such assets to the extent that, based on the weight of all available evidence, it is more likely than not that all or a portion of the deferred tax assets will not be realized. In assessing the likelihood of future realization of our deferred tax assets, we placed significant weight on our history of generating U.S. tax losses, including in the first ~~half~~nine months of 2020. As a result, we have a full valuation allowance against our net deferred tax assets, including net operating loss carryforwards, and tax credits related primarily to research and development. We expect to maintain a full valuation allowance for the foreseeable future.

We require cash to fund our operations, including outlays for infrastructure growth, acquisitions, geographic expansion, expanding our sales and marketing activities, research and development efforts, and working capital for our growth. To date, we have financed our operations primarily through cash received from customers for our solutions, public offerings of our common stock, private placements, and bank borrowings. As of ~~June~~September 30, 2020, we had ~~$474.4 million~~almost $1.1 billion of cash and cash equivalents, most of which was held in money market accounts. On October 5, 2020, we acquired all the outstanding equity of Transaction Tax Resources, Inc. (“TTR”) for total cash consideration of approximately $377 million. Approximately $57.6 million of the purchase price will be paid to TTR shareholders over the next 36 months, subject to reduction for certain indemnifications and other potential obligations of the TTR shareholders. In addition, $26.4 million of the purchase price will be paid to TTR’s founder and shareholder following the achievement of certain TTR performance metrics during the 2021 and 2022 fiscal years.

We had a loan and security agreement with Silicon Valley Bank and Ally Bank (the “Lenders”) that consisted of a $50.0 million revolving credit facility (the “Credit Facility”). On June 25, 2019, we terminated the Credit Facility. As of ~~June~~September 30, 2020, we had no credit facilities in place and had no borrowings outstanding.

As of ~~June~~September 30, 2020, our cash and cash equivalents included proceeds from our August 2020, June 2019 and ~~our~~ June 2018 public offerings of common stock. We intend to continue to increase our operating expenses and capital expenditures to support the growth in our business and operations. We may also use our cash and cash equivalents to acquire complementary businesses, products, services, technologies, or other assets. We believe that our existing cash and cash equivalents of ~~$474.4 million~~$1.1 billion as of ~~June~~September 30, 2020 will be sufficient to meet our anticipated cash needs for at least the next 12 months. Our financial position and liquidity are, and will be, influenced by a variety of factors, including our growth rate, the timing and extent of spending to support research and development efforts, the continued expansion of sales and marketing spending, the introduction of new and enhanced solutions, the cash paid for any acquisitions, and the continued market acceptance of our solutions.

The following table shows our cash flows from operating activities, investing activities, and financing activities for the stated periods:

Financing Activities		25,333			334,092			593,159			340,454

Our largest source of operating cash is cash collections from our customers for subscriptions and returns services. Our primary uses of cash from operating activities are for employee-related expenditures, commissions paid to our partners, marketing expenses, software hosting costs, and facilities expenses. Cash used in operating activities is comprised of our net loss adjusted for certain non-cash items, including stock-based compensation, depreciation and amortization, other non-cash ~~charges,~~income and expenses, and net changes in operating assets and liabilities.

For the ~~six~~nine months ended ~~June~~September 30, 2020, net cash ~~used in~~provided by operating activities was ~~$16.1~~$11.8 million compared to net cash ~~used~~provided of ~~$0.4~~$5.4 million for the~~six~~ nine months ended ~~June~~September 30, 2019. The increase in cash ~~used in~~provided by operations of ~~$15.7~~$6.4 million was due primarily to ~~higher annual incentive bonus payments of $10.4 million and higher software subscription payments of $3.7 million. In addition, we offered~~ a sales promotion beginning in the second quarter of 2020 with extended credit terms for new customers, and we extended payment terms to some of our existing customers, resulting in an estimated $5.0 million reduction in cash collected from customers during the first six months of 2020. This was partially offset by a $2.9$5.1 million decrease in cash used due to our deferral of U.S. employer payroll tax payments under the CARES Act. We pay bonuses under our annual incentive plan each March for the previous year ended performance. During the first quarter of each year, we also pay a significant portion of our annual software subscription licenses. These payments were higher in the first half of 2020 due to timing of payments and an increased spend compared to the same period of the prior year due primarily to new software subscriptions for information technology security and reporting tools and more user licenses for renewing subscriptions due to higher headcount. We expect to continue our sales promotion during the third quarter of 2020, and we expect to continue to defer payment of employer payroll tax payments through the rest of 2020.

Our investing activities primarily include cash outflows related to purchases of property and equipment, changes in customer fund assets, and, from time-to-time, the cash paid for asset or business acquisitions.

For the ~~six~~nine months ended ~~June~~September 30, 2020, cash used in investing activities was ~~$1.6~~$7.4 million, compared to cash used of ~~$34.3~~$41.6 million for the~~six~~ nine months ended ~~June~~September 30, 2019. The decrease in cash used in investing activities of ~~$32.7~~$34.3 million was due primarily to a reduction in cash paid for acquisitions of businesses of ~~$17.3~~$30.3 million, ~~a decrease~~an increase in customer fund assets of ~~$2.0~~$1.7 million in the first ~~half~~nine months of 2020 compared to an increase of ~~$11.9~~$4.0 million in the prior period, and lower capital expenditures of ~~$1.4~~$1.5 million. In the first ~~half~~nine months of 2019, we acquired substantially all the assets of Compli, Indix, and ~~Indix~~Portway for total cash consideration of ~~$17.3~~$30.3 million.

Our financing activities primarily include cash inflows and outflows from issuance and repurchases of capital stock, our employee stock purchase plan, deferred cash payments made in connection with acquisitions of businesses, and changes in customer fund obligations.

For the ~~six~~nine months ended ~~June~~September 30, 2020, cash provided by financing activities was ~~$25.3~~$593.2 million compared to cash provided of ~~$334.1~~$340.5 million for the~~six~~ nine months ended ~~June~~September 30, 2019. This ~~decrease~~increase in cash provided by financing activities of ~~$308.8~~$252.7 million was due primarily to ~~a decrease~~an increase in cash proceeds from offerings of our common stock of ~~$274.7~~$281.6 million, partially offset by a ~~$15.0~~$20.9 million decrease in cash proceeds from exercise of stock options, a ~~$1.9~~$3.4 million increase in deferred cash payments related to business combination earnouts, a $2.8 million increase in deferred cash payments related to business combinations, a $1.0 million decrease in cash proceeds from common stock purchased under our employee stock purchase plan, and a ~~$3.8~~$1.7 million increase ~~in cash paid related to business combination earnouts, and a $2.0 million decrease~~ in customer fund obligations in the first ~~half~~nine months of 2020 compared to a ~~$11.8~~$4.0 million increase in customer fund obligations in the prior period.

We maintain trust accounts with financial institutions, which allows our customers to outsource their tax remittance functions to us. We have legal ownership over the accounts utilized for this purpose. Funds held from customers represent cash and cash equivalents that, based upon our intent, are restricted solely for satisfying the obligations to remit funds relating to our tax remittance services. Funds held from customers are not commingled with our operating funds, but typically are deposited with funds also held on behalf of our other customers.

Customer fund obligations represent our contractual obligations to remit collected funds to satisfy customer tax payments. Customer fund obligations are reported as a current liability on the consolidated balance sheets, as the obligations are expected to be settled within one year. Cash flows related to the cash received from and paid on behalf of customers are reported as follows:

InDuring the ~~first half of 2020,~~nine months ended September 30,2020, our purchase commitments increased approximately ~~$120~~$128 million compared to December 31, 2019, primarily related to software hosting and software license subscriptions that extend up to five years beyond ~~June~~September 30, 2020. InDuring the ~~second quarter of~~nine months ended September 30, 2020, our operating lease obligations increased ~~$1.4~~$7.3 million for additional office space ~~that has not yet commenced~~and equipment that extends up to five years beyond ~~June~~September 30, 2020. There were no other material changes to our contractual obligations as of ~~June~~September 30, 2020 compared to December 31, 2019.

We did not have any off-balance sheet arrangements in the ~~six~~nine months ended ~~June~~September 30, 2020 or 2019.

In addition to our results determined in accordance with GAAP, we have calculated non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP gross margin, non-GAAP research and development expense, non-GAAP sales and marketing expense, non-GAAP general and administrative expense, non-GAAP operating income (loss), non-GAAP net income (loss), free cash flow, and calculated billings, which are non-GAAP financial measures. We have provided tabular reconciliations of each of these non-GAAP financial measures to its most directly comparable GAAP financial measure.

Management uses these non-GAAP financial measures to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, and to evaluate financial performance and liquidity. In addition, because we recognize subscription revenue ratably over the subscription term, management uses calculated billings to measure our subscription sales activity for a particular period, to compare subscription sales activity across particular periods, and as a potential indicator of future subscription revenue, the actual timing of which will be affected by several factors, including subscription start date and duration. We believe that non-GAAP financial measures provide useful information to investors and others in understanding and evaluating our results, prospects, and liquidity period-over-period without the impact of certain items that do not directly correlate to our performance and that may vary significantly from period to period for reasons unrelated to our operating performance, as well as comparing our financial results to those of other companies. Our definitions of these non-GAAP financial measures may differ from the definitions used by other companies and therefore comparability may be limited. In addition, other companies may not publish these or similar metrics. Thus, our non-GAAP financial measures should be considered in addition to, not as a substitute for, or in isolation from, measures prepared in accordance with GAAP.

We encourage investors and others to review our financial information in its entirety, not to rely on any single financial measure and to view non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP gross margin, non-GAAP research and development expense, non-GAAP sales and marketing expense, non-GAAP general and administrative expense, non-GAAP operating income (loss), non-GAAP net income (loss), free cash flow, and calculated billings in conjunction with the related GAAP financial measure.

The following schedules reflect our non-GAAP financial measures and reconcile our non-GAAP financial measures to the related GAAP financial measures:

There have been no material updates or changes to our critical accounting policies and estimates compared to the critical accounting policies and estimates described in our 2019 Annual Report.

For further information on recent accounting pronouncements, refer to Note 2 in the consolidated financial statements contained within this Quarterly Report on Form 10-Q.

We had cash and cash equivalents of ~~$474.4 million~~$1.1 billion and $467.0 million as of ~~June~~September 30, 2020 and December 31, 2019, respectively. We maintain our cash and cash equivalents in deposit accounts and money market funds with financial institutions. Due to the short-term nature of these instruments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. Declines in interest rates, however, would reduce future interest income.

~~On June 25, 2019, we terminated our Credit Facility.~~ At ~~June~~September 30, 2020, we had no credit facilities in place and had no borrowings outstanding. Any debt we incur in the future may bear interest at variable rates and may expose us to risk related to changes in interest rates.

Our revenue and expenses are primarily denominated in U.S. dollars. For our foreign operations, the majority of our revenues and expenses are denominated in other currencies, such as the Brazilian Real, British Pound, Euro, and Indian Rupee. Decreases in the relative value of the U.S. dollar as compared to these currencies may negatively affect our revenue and other operating results as expressed in U.S. dollars. For the three months ended ~~June~~September 30, 2020 and 2019, approximately 6% of our revenues were generated in currencies other than U.S. dollars. For the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, approximately 6% ~~and 7%, respectively,~~ of our revenues were generated in currencies other than U.S. dollars.

We have experienced and will continue to experience fluctuations in our net loss as a result of transaction gains or losses related to revaluing certain current asset and current liability balances that are denominated in currencies other than the functional currency of the entities in which they are recorded. We recognized immaterial amounts of foreign currency gains and losses in each of the periods presented. We have not engaged in the hedging of our foreign currency transactions to date. We may in the future hedge selected significant transactions denominated in currencies other than the U.S. dollar as we expand our international operations and our risk grows.

We do not believe that inflation had a material effect on our business, financial condition, or results of operations in the last fiscal year or the first ~~half~~nine months of 2020. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, financial condition, and results of operations.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation (pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Exchange Act as of ~~June~~September 30, 2020.

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our company’s reports filed under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were ineffective as of ~~June~~September 30, 2020 due to the material weakness identified as of December 31, 2019 and described below. Management, under the direction and supervision of our chief executive officer and chief financial officer, has performed additional review and analyses and other post-closing procedures and has concluded that, notwithstanding the material weakness in our internal control over financial reporting, the consolidated financial statements for the periods covered by and included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with GAAP.

As of December 31, 2019, the Company concluded that it had a material weakness as it lacks adequate controls to effectively design, implement, and operate process-level and information technology controls to sufficiently mitigate risks of material misstatement associated with certain complex business processes and changes in those processes or applicable accounting standards. This material weakness led to the following individual significant deficiencies:

The Company continues working to remediate the material weakness and resulting significant deficiencies in internal control over financial reporting and is taking steps to improve the internal control environment. During the first ~~half~~nine months of 2020, the Company formed an internal working group to detail and implement specific remediation plans for its control deficiencies, engaged with outside consultants to provide advice and assistance, and hired additional personnel to assist with performing and monitoring internal control activity. The Company has completed the following:

To remediate the material weakness and resulting significant deficiencies, the Company will require additional time to demonstrate the effectiveness of the remediation efforts. The material weakness will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Notwithstanding the material weakness, management has concluded that the consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q present fairly, in all material respects, our financial position, results of operations, and cash flows in conformity with GAAP.

Other than the changes described above regarding the ~~enhanced processes~~system controls and ~~additional training implemented~~user access reviews and controls that the Company is working to implement in connection with the remediation of the material weakness and resulting significant deficiencies, there were no changes in our internal control over financial reporting in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the period covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management recognizes that a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud or error, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

From time to time, we may be subject to legal proceedings arising in the ordinary course of business. In addition, from time to time, third parties may assert intellectual property infringement claims against us in the form of letters and other forms of communication. Regardless of the outcome of any existing or future litigation, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

On October 22, 2018, PTP OneClick, LLC (“PTP”) filed a lawsuit against Avalara, Inc. in the United States District Court for the Eastern District of Wisconsin. The lawsuit alleges that making, using, offering to sell, and selling AvaTax, Avalara Returns, and TrustFile (the “Avalara Products”) infringe U.S. Patent No. 9,760,915 held by PTP and also alleges unspecified trade secret misappropriation, unfair competition, and breach of contract. PTP seeks judgments of willful patent infringement, willful trade secret misappropriation, unfair competition, and breach of contract. PTP requests preliminary and permanent injunctions to enjoin us from making, using, offering to sell, and selling the Avalara Products along with treble damages and attorneys’ fees. Based upon our review of the complaint and the specified patent, we believe we have meritorious defenses to PTP’s claims. On November 7, 2018, we moved to dismiss the lawsuit and to have the patent held invalid, and also have moved to transfer the matter to the United States District Court located in Seattle, Washington. On April 30, 2019, the United States District Court for the Eastern District of Wisconsin granted our motion to transfer, reserving resolution of the motion to dismiss for the United States District Court for the Western District of Washington. On October 7, 2019, the United States District Court for the Western District of Washington invalidated the patent and dismissed the patent and unfair competition claims with prejudice but did not dismiss the trade secret misappropriation or breach of contract claims. On March 5, 2020, we filed a motion for summary judgment. On May 27, 2020, the United States District Court for the Western District of Washington entered summary judgment in favor of Avalara, Inc. disposing of the remaining trade secret misappropriation and breach of contract claims. Plaintiff filed a notice of appeal but subsequently withdrew the notice. On July 7, 2020, the United States District Court for the Western District of Washington dismissed the appeal with prejudice.

Other than the item discussed below, there have been no material changes to the Company’s Risk Factors as disclosed in our 2019 Annual Report.

The ~~recent~~ novel coronavirus pandemic could adversely affect our business, financial condition, results of operations, and cash flows.

The ~~recent~~ novel coronavirus (“COVID-19”) pandemic has resulted in widespread disruptions across the United States and the world, including in the states and countries in which we operate. As a result of the COVID-19 pandemic, we ~~have seen~~experienced and, in the future, may experience decreased demand for our solutions from customers as well as slower collections on accounts receivable. Because we sell our solutions primarily on a subscription basis, the effect of the pandemic may not be fully reflected in our operating results until future periods. Like many companies, including our customers and prospects, most of our employees are working from home, we have limited all non-essential business travel, and we have modified certain other business practices to conform to government restrictions and best practices encouraged by government and regulatory authorities. While we are developing and implementing risk mitigation plans and have reduced our pace of hiring, decreased costs associated with travel and marketing, and delayed certain other non-essential expenditures, these measures may not be sufficient to prevent adverse impacts on our business and financial condition from COVID-19. The degree to which the COVID-19 pandemic may impact our results of operations and financial condition is unknown at this time and will depend on future developments, including the geographic spread of COVID-19, the severity and the duration of the pandemic, and further actions that may be taken by governmental authorities or businesses.
