Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Consolidation and Presentation The accompanying unaudited consolidated financial statements include the accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The unaudited consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and reflect all normal and recurring adjustments that are, in the opinion of management, necessary for a fair statement of the Company’s financial position, results of operations, changes in stockholders’ equity, and cash flows for the periods presented. The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023 or for any other future annual or interim period. The unaudited consolidated balance sheet as of December 31, 2022 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis. All significant intercompany accounts and transactions have been eliminated. There are no items of comprehensive income. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company for the year ended December 31, 2022 . Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities as of and during the reporting period. The Company bases estimates and assumptions on historical experience when available and on various factors that it believes to be reasonable under the circumstances. Significant estimates reflected in these unaudited consolidated financial statements include, but are not limited to, the allowance for credit losses and returns, useful lives assigned to fixed and intangible assets, capitalization of internal-use software, deferral of customer origination costs, the fair value of intangible assets acquired in a business combination, the fair value of goodwill, and the recoverability of deferred income taxes. The Company assesses estimates on an ongoing basis; however, actual results could materially differ from those estimates. Concentrations Significant Services A substantial portion of the Company’s revenue is derived from interchange fees earned on payment transactions processed as virtual commercial cards (“VCC”). The Company utilizes service providers to process these transactions. Revenue from one service provider represented 14 % and 22 % of total revenue for the three months ended September 30, 2023 and 2022, respectively, and 18 % and 26 % of total revenue for the nine months ended September 30, 2023 and 2022, respectively. Accounts receivable from this service provider represented 21 % and 28 % of accounts receivable, net as of September 30, 2023 and December 31, 2022, respectively . Revenue from a second provider represented 31 % and 32 % of total revenue for the three months ended September 30, 2023 and 2022, respectively, and 29 % and 27 % of total revenue for the nine months ended September 30, 2023 and 2022, respectively. Accounts receivable from this second service provider represented 35 % and 29 % of accounts receivable, net as of September 30, 2023 and December 31, 2022, respectively. Future regulation or changes by the card brand payment networks could have a substantial impact on interchange rates and the Company’s revenue from VCC transactions. If interchange rates decline, whether due to actions by the card brand payment networks, merchant/suppliers availing themselves of lower rates, or future regulation, the Company’s total operating revenues, operating results, prospects for future growth and overall business could be materially affected. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less at the time of purchase that are not recorded as marketable securities to be cash equivalents. The carrying values of cash and cash equivalents approximate their fair values due to the short-term nature of these instruments. Cash in the Company’s bank accounts may exceed federally insured limits. Marketable Securities Marketable securities consist of short-term investments in short-term commercial paper and various U.S. government backed securities. To reflect its intention, the Company classifies its marketable securities as held-to-maturity at the time of purchase. As a result, the marketable securities are recorded at amortized cost and any gains or losses realized upon maturity are reported in other income (expense) in the consolidated statements of operations. Accounts Receivable, Supplier Advances and Allowance for Credit Losses Accounts receivable represent amounts due from the Company’s VCC service providers for interchange fees earned and from buyer customers who have been invoiced for the use of the Company’s software offerings, but for whom payments have not been received. Accounts receivable from VCC service providers are presented net of an allowance for returns for transactions subsequently canceled that do not ultimately settle through the payment network. Accounts receivable from buyer customers are presented net of allowances for credit losses and returns. The Company estimates expected credit losses related to accounts receivable balances based on a review of available and relevant information including current economic conditions, projected economic conditions, historical loss experience, account aging, and other factors that could affect collectability. Expected credit losses are determined individually or collectively depending on whether the accounts receivable balances share similar risk characteristics. The allowance for returns for VCC transactions subsequently canceled are assessed at each period end and recognized as a reduction of revenue. The allowances for buyer customer’s credit losses and returns are assessed at each period end and are recognized as bad debt expense within general and administrative expenses in the consolidated statements of operations and as a reduction of revenue, respectively. A buyer customer receivable is written off against the allowance when it is determined that all collection efforts have been exhausted and the potential for recovery is considered remote. Historically, losses related to customer nonpayment have been immaterial and most of the accounts receivable balances have been current. Supplier advances receivable represent amounts that have been advanced as part of the AvidXchange’s Invoice Accelerator product but have not been collected. Advances are collected from the buyer customer once the buyer initiates the transfer of funds for the invoice that was previously advanced. If the buyer does not transfer the funds as expected, the Company is exposed to losses. The Company’s experience with such delinquencies by buyer customers has been immaterial. Supplier advances receivable are stated net of expected credit losses. The Company estimates expected credit losses related to supplier advances receivable balances based on a review of available and relevant information including current economic conditions, projected economic conditions, historical loss experience, account aging, and other factors that could affect collectability. Expected credit losses are determined individually or collectively depending on whether the accounts receivable balances share similar risk characteristics. The allowance for credit losses for supplier advances is assessed at period end and the measurement of the allowance is included as a component of cost of revenues in the Company’s consolidated statements of operations. Supplier advances receivable balances are charged against the allowance when the Company determines it is probable the receivable will not be recovered after collection efforts and legal actions have been exhausted. The Company classifies the fees charged to supplier customers as cash flows from operating activities with the remaining accelerated advancements and recoupments classified as cash flows from investing activities on a net basis within the consolidated statements of cash flows. Restricted Funds Held for Customers and Payment Service Obligations Restricted funds held for customers and the corresponding liability of payment service obligations represent funds that are collected from customers for payments to their suppliers. The Company determines the balances of restricted funds held for customers, and the corresponding payment services obligations, by reconciling cash held by financial institutions and the corresponding payments in transit at the end of each period. The balance of these obligations may fluctuate from period to period depending on the timing of the period end and the timing of when outstanding payments clear with financial institutions. The Company is registered as a money services business with the Financial Crimes Enforcement Network. Payment service obligations are comprised of outstanding daily transaction liabilities per state regulatory average daily transaction liability report requirements and other unregulated settlements with payees, which do not constitute a regulatory liability event under reporting requirements. As of September 30, 2023 As of December 31, 2022 Outstanding Transaction Liabilities $ 1,195,559 $ 1,242,155 Other unregulated settlements 30,657 41,669 Total payment service obligations $ 1,226,216 $ 1,283,824 The Company historically transmitted buyer customer funds using a legacy model pursuant to which buyer customer funds are held in trust accounts that are maintained and operated by a trustee pending distribution to suppliers in accordance with instructions provided through the Company’s platform. The Company is not the trustee or beneficiary of the trusts which hold these buyer deposits; accordingly, the Company does not record these assets and offsetting liabilities on its consolidated balance sheets. The Company has largely phased out this model although certain banks that resell its products and services continue to leverage a similar structure. The Company contractually earns interest on funds held for certain buyers. The amount of Company and bank customer funds held in all trust-related accounts was approximately $ 20,449 and $ 135,058 as of September 30, 2023 and December 31, 2022, respectively. The Company has transitioned most payment transmission activity to the money transmitter license model and obtained a money transmitter license in all states which require licensure. This model enables AvidXchange to provide commercial payment services to businesses through its “for the benefit of customer” bank accounts, also known as FBO, that are restricted for such purposes. The restricted funds held for customers are restricted for the purpose of satisfying the customer’s supplier obligations and are not available for general business use by the Company. The Company maintains these funds in liquid cash accounts and contractually earns interest on these funds held for customers. These funds are recognized as a restricted cash asset and a corresponding liability is recorded for payments due to their suppliers on the Company’s consolidated balance sheets. Restricted funds held for customers are included in the cash and cash equivalents on the consolidated statements of cash flows. Stock-Based Compensation Compensation cost for stock-based awards issued to employees and outside directors, including stock options and restricted stock units (“RSUs”), is measured at fair value on the date of grant. The fair value of stock options is estimated using a Black-Scholes option-pricing model, while the fair value of RSUs is determined using the fair value of the Company’s underlying common stock. Stock-based compensation expense is recognized on a straight-line basis over the requisite service period of the award. Stock-based compensation expense for RSUs with performance conditions is recognized over the requisite service period on an accelerated-basis as long as the performance condition in the form of a specified liquidity event is probable to occur. In the case of equity issued in lieu of cash bonus, expense is recognized in the period the cash bonus was earned. Nonqualified Deferred Compensation Plan The Company adopted a nonqualified, deferred compensation plan effective October 1, 2015, which is an unfunded plan created for the benefit of a select group of management or highly compensated employees. The purpose of the plan is to attract and retain key employees by providing them with an opportunity to defer receipt of a portion of their compensation. It is exempt from the participation, vesting, funding, and fiduciary requirements set forth in Title I of the Employee Retirement Income Security Act of 1974, as amended. Deferred amounts are not subject to forfeiture and are deemed invested among investment funds offered under the nonqualified deferred compensation plan, as directed by each participant. The Company has established a ‘rabbi trust’ that serves as an investment to shadow the deferred compensation plan liability. The assets of the rabbi trust primarily consist of trust-owned life insurance policies which are recorded at cash surrender value and are included in other noncurrent assets. The change in cash surrender value of the life insurance policies in the rabbi trust is recorded in other income (expense) on the Company's unaudited consolidated statements of operations. The assets of the rabbi trust are general assets of the Company and as such, would be subject to the claims of creditors in the event of bankruptcy or insolvency. The related deferred compensation liabilities are included in other long-term liabilities. The Company has recorded these assets and liabilities at their fair value. In association with this plan, $ 1,704 and $ 1,611 were included in other noncurrent assets and $ 2,116 and $ 1,803 were included in noncurrent liabilities as of September 30, 2023 and December 31, 2022 , respectively, on the Company's unaudited consolidated balance sheets. Contingent Liabilities Contingent liabilities require significant judgment in estimating potential losses for legal claims. The Company reviews significant new claims and litigation for the probability of an adverse outcome. Estimates are recorded as liabilities when it is probable that a liability has been incurred and the amount of the loss is reasonably estimable. Disclosure is required when there is a reasonable possibility that the ultimate loss will materially exceed the recorded provision. Contingent liabilities are often resolved over long periods of time. Estimating probable losses requires analysis of multiple forecasts that often depend on judgments about potential actions by third parties such as regulators, and the estimated loss can change materially as individual claims develop. New Accounting Pronouncements Recently Adopted Accounting Standards In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, Financial Instruments, Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the guidance on the impairment of financial instruments by requiring measurement and recognition of expected credit losses for most financial assets, including trade receivables, and other instruments that are not measured at fair value through net income (the “CECL” framework). ASU 2016-13 was effective for public business entities for fiscal years beginning after December 15, 2019. Under the Company's prior status as an emerging growth company, the Company had delayed the adoption of ASU 2016-13. The Company lost its status as an emerging growth company on December 31, 2022, and ASU 2016-13 became effective for the Company as of January 1, 2022. On adoption, the Company recorded approximately $ 1,000 cumulative effect adjustment to accumulated deficit in connection with expected credit losses on its accounts receivable and supplier advances receivable. The adoption had an insignificant impact on the 2022 information presented in the Company’s 2022 quarterly reports on Form 10-Q. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This standard requires contract assets and contract liabilities from contracts with customers that are acquired in a business combination to be recognized and measured as if the acquirer had originated the original contract. The Company adopted this standard on January 1, 2023 , and will apply its provisions prospectively to business combinations occurring on or after this date. The adoption of this guidance did no t have an impact on the Company's consolidated financial statements. Accounting Pronouncements Issued but Not Yet Adopted In March 2023, the FASB issued ASU No. 2023-01, Leases (Topic 842): Common Control Arrangements. The amendments in this update that apply to public business entities clarify the accounting for leasehold improvements associated with common control leases. This update is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The Company does not expect the adoption of this update to have a material effect on its consolidated financial statements. |
