Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company and Significant Accounting Policies and Estimates	The Company and Significant Accounting Policies and Estimates Model N, Inc. (“Model N,” “we,” “us,” “our,” and “the Company”) was incorporated in Delaware on December 14, 1999. The Company is a provider of cloud revenue management solutions for the life sciences and high tech industries. The Company’s software and business services enable its customers to maximize revenues and reduce revenue compliance risk by transforming their revenue life cycle from a series of tactical, disjointed operations into a strategic end-to-end process, which enables them to manage the strategy and execution of pricing, contracting, incentives and rebates. The Company’s corporate headquarters are located in San Mateo, California, with additional offices in the United States, India and Switzerland. Fiscal Year The Company’s fiscal year ends on September 30. References to fiscal year 2021, for example, refer to the fiscal year ending September 30, 2021. Basis for Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated balance sheet as of September 30, 2020 has been derived from the audited financial statements which are included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020 (“the Annual Report”) on file with the SEC. The unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Annual Report. In the opinion of management, the unaudited interim consolidated financial statements include all the normal recurring adjustments necessary to present fairly our condensed consolidated financial statements. The results of operations for the six months ended March 31, 2021 are not necessarily indicative of the operating results for the full fiscal year 2021 or any future periods. The condensed consolidated financial statements include the accounts of Model N and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates include revenue recognition, liability and equity allocation of convertible senior notes, legal contingencies, income taxes, stock-based compensation and valuation of goodwill and intangibles. These estimates and assumptions are based on management’s best estimates and judgment. Management regularly evaluates its estimates and assumptions using historical experience and other factors. However, actual results could differ significantly from these estimates. COVID-19 The Company is subject to risks and uncertainties as a result of the COVID-19 pandemic. At this point, the extent to which COVID-19 may impact the Company’s financial condition or results of operations is uncertain. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require us to update our estimates, judgments or revise the carrying value of our assets or liabilities. The estimates discussed above may change, as new events occur and additional information is obtained, and are recognized in the condensed consolidated financial statements as soon as they become known. New Accounting Pronouncements Recently Adopted Accounting Guidance In August 2018, the FASB issued ASU 2018-15, Intangibles (Topic 350), Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which 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. This standard also requires customers to amortize the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement. ASU 2018-15 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. The Company adopted this guidance in the first quarter of fiscal year 2021 and it did not have a material impact on the condensed consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model which requires the use of forward-looking information to calculate credit loss estimates. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. ASU 2016-13 requires a cumulative effect adjustment to the balance sheet as of the beginning of the first reporting period in which the guidance is effective. The Company adopted this guidance in the first quarter of fiscal year 2021 and it did not have a material impact on the condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes, which simplifies the accounting for incomes taxes by removing certain exceptions to the general principles in Topic 740 and amending existing guidance to improve consistent application. ASU 2019-12 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the impact this standard will have on its condensed consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40), Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. ASU 2020-06 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2021, with early adoption permitted. The Company is currently evaluating the impact this standard will have on its condensed consolidated financial statements. Significant Accounting Policies There have been no changes in the significant accounting policies from those that were disclosed in the audited consolidated financial statements for the fiscal year ended September 30, 2020 included in the Annual Report on Form 10-K.

Revenues from Contracts with Cu

Revenue from Contract with Customer [Abstract]
Revenues from Contracts with Customers	Revenues from Contracts with Customers Revenue Recognition The Company derives revenues primarily from subscription revenues and professional services revenues. Disaggregation of Revenues See Note 13, Geographic Information, for information on revenue by geography. Customer Contract Balances The following table reflects contract balances related to contracts with customers (in thousands): As of As of Accounts receivable, net $ 40,754 $ 35,796 Contract asset 5,442 4,482 Deferred revenue 56,641 51,786 Capitalized contract acquisition costs 8,932 7,506 Accounts Receivable Accounts receivable represents the Company’s right to consideration that is unconditional, net of allowances for doubtful accounts. The allowance for doubtful accounts is based on management’s assessment of the collectability of accounts receivable amounts. Contract Asset Contract asset represents revenue that has been recognized for satisfied performance obligations for which the Company does not have an unconditional right to consideration. Deferred Revenue Deferred revenue, which is a contract liability, consists of amounts that have been invoiced and for which the Company has the right to bill, but that have not been recognized as revenue because the related goods or services have not been transferred. The non-current portion of deferred revenue is included in other long-term liabilities in the condensed consolidated balance sheets. During the three and six months ended March 31, 2021, the Company recognized revenue of $23.0 million and $35.9 million, respectively, that was included in the deferred revenue balances at the beginning of the periods. During the three and six months ended March 31, 2020, the Company recognized revenue of $19.2 million and $31.6 million, respectively, that was included in the deferred revenue balances at the beginning of the periods. Capitalized Contract Acquisition Costs The Company capitalizes incremental costs incurred to acquire contracts with customers, primarily sales commissions, for which the associated revenue is expected to be recognized in future periods. The Company incurs these costs in connection with both initial contracts and renewals. Such costs for renewals are not considered commensurate with those for initial contracts given the substantive difference in commission rates in proportion to their respective contract values. The costs in connection with initial contracts and renewals are deferred and amortized over an expected customer life of five years and over the renewal term, respectively, which corresponds to the period of benefit to the customer. The Company determined the period of benefit by considering the Company’s history of customer relationships, length of customer contracts, technological development and obsolescence, and other factors. The current and non-current portion of capitalized contract acquisition costs are included in other current assets and other assets on the condensed consolidated balance sheets. Amortization expense is included in sales and marketing expenses on the condensed consolidated statements of operations. As of March 31, 2021, the current and non-current portions of capitalized contract acquisition costs were $2.8 million and $6.1 million, respectively. As of September 30, 2020, the current and non-current portions of capitalized contract acquisition costs were $2.3 million and $5.2 million, respectively. The Company amortized $0.7 million and $1.4 million of contract acquisition costs during the three and six months ended March 31, 2021, respectively. The Company amortized $0.6 million and $1.2 million of contract acquisition costs during the three and six months ended March 31, 2020, respectively. For the three and six months ended March 31, 2021 and 2020, there was no impairment related to capitalized contract acquisition costs. Customer Deposits Customer deposits primarily relate to payments received from customers which could be refundable pursuant to the terms of the related arrangement. These amounts are included in accrued liabilities on the condensed consolidated balance sheets. Customer deposits were immaterial as of March 31, 2021 and September 30, 2020. Standard payment terms to customers generally range from thirty to ninety days; however, payment terms and conditions in our customer contracts may vary. In some cases, customers prepay for subscription and services in advance of the delivery; in other cases, payment is due as services are performed or in arrears following the delivery. Performance Obligations Remaining performance obligations represent non-cancelable contracted revenue that has not yet been recognized, which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. As of March 31, 2021, the aggregate amount of the transaction price allocated to performance obligations either unsatisfied or partially unsatisfied was $203.9 million, 53% of which we expect to recognize as revenue over the next 12 months and the remainder thereafter.

Leases [Abstract]
Leases	Leases The Company leases facilities under noncancelable operating leases with lease terms between three years and 10 years. Certain leases include options to extend or terminate the lease. The Company factored into the determination of lease payments the options that it is reasonably certain to exercise. Operating lease costs were $1.0 million and $1.8 million for the three and six months ended March 31, 2021, respectively, and $0.8 million and $1.7 million for the three and six months ended March 31, 2020, respectively. Short-term lease costs, variable lease costs, and sublease income were immaterial for the three and six months ended March 31, 2021 and 2020. Cash flow information related to operating leases is as follows (in thousands): Six months ended Six months ended Cash paid for amounts included in the measurement of operating lease liabilities $ 1,191 $ 1,804 Operating lease ROU assets obtained in exchange for new operating lease liabilities 12,592 578 The Company’s headquarters lease commenced on December 1, 2020 which resulted in an increase of ROU assets of $10.3 million.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, debt and certain accrued liabilities. The Company regularly reviews its financial instruments portfolio to identify and evaluate such instruments that have indications of possible impairment. The Company estimates the fair value of its financial instruments when there is no readily available market data, which involves some level of management estimation and judgment and may not necessarily represent the amounts that could be realized in a current or future sale of these assets. The table below sets forth the Company’s marketable securities which are measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands): Reported as: Amortized Cost Unrealized Gains Unrealized Losses Fair Value Cash and Cash Equivalents As of March 31, 2021 Level 1: Money market funds $ 114,826 $ — $ — $ 114,826 $ 114,826 Total $ 114,826 $ — $ — $ 114,826 $ 114,826 As of September 30, 2020 Level 1: Money market funds $ 31,915 $ — $ — $ 31,915 $ 31,915 US Treasury securities 149,982 — — 149,982 149,982 Total $ 181,897 $ — $ — $ 181,897 $ 181,897 The Company’s financial instruments not measured at fair value on a recurring basis include cash, accounts receivable, accounts payable and certain accrued liabilities. These financial instruments are reflected in the financial statements at cost and approximate their fair value due to their short-term nature. See Note 6 for the fair value measurement of the Company’s derivative contracts and Note 7 for the fair value measurement of the Company’s convertible senior notes.

Goodwill and Intangible Assets Disclosure [Abstract]
Acquisition, Goodwill, and Intangible Assets	Acquisition, Goodwill, and Intangible Assets Acquisition On December 31, 2020, the Company acquired certain assets, properties and rights and certain liabilities and obligations from Deloitte & Touche LLP’s pricing and contracting solutions business for a contractual purchase price of $60.0 million subject to net working capital adjustments (the “Acquisition”). The acquired business operates primarily in the same markets as the Company’s existing operations. The reason for the Acquisition was to increase the Company’s addressable market and expand the opportunity to sell existing Model N products. This Acquisition has been accounted for as a business combination. The Company has included the results of the acquired business in its condensed consolidated financial statements since the date of Acquisition. The Company incurred $2.4 million of acquisition-related expense during the six months ended March 31, 2021, which was recorded as general and administrative expenses. The total purchase consideration was $57.8 million reflecting a $2.2 million net working capital adjustment from the contractual purchase price. The Company paid $56.8 million of purchase consideration in cash during the six months ended March 31, 2021. The purchase price was allocated to assets acquired and liabilities assumed based upon their estimated fair values as of the date of the acquisition. The excess of the purchase price over the estimated fair value of the net assets acquired was recorded as goodwill. The following table sets forth the preliminary allocation of the purchase price in connection with the Acquisition (in thousands): Acquisition Date Fair Value Accounts receivable $ 3,844 Property and equipment, net 511 Operating lease right-of-use assets 2,764 Goodwill 26,382 Intangible assets 28,210 Total assets acquired 61,711 Operating lease liabilities, current portion 656 Deferred revenue, current portion 1,549 Operating lease liabilities, less current portion 1,657 Total liabilities assumed 3,862 Total purchase price $ 57,849 The fair value of the assets acquired and liabilities assumed is subject to change within the measurement period (up to one year from the Acquisition date), as the valuation is finalized and if new information becomes available. The Company does not expect the change to be material. Intangible assets included customer relationships of $15.5 million, developed technology of $10.2 million, non-compete agreements of $1.6 million, and trade name of $0.9 million, which are amortized on a straight-line basis over 15 years, 6 years, 5 years, and 3 years, respectively, and over a weighted average period of 10.8 years. The Company applied significant judgment in determining the fair value of the intangible assets acquired, which involved the use of significant estimates and assumptions including customer attrition rate, royalty rate and technology migration curve. Goodwill is comprised of expected synergies for the combined operations and the assembled workforce acquired in the Acquisition. This goodwill is deductible for income tax purposes. The Acquisition contributed $6.5 million to the Company’s revenues and increased operating loss, which approximated net loss, by $2.4 million during the three months ended March 31, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging	Derivative Instruments and HedgingThe Company uses foreign currency forward contracts to hedge a portion of the forecasted foreign currency-denominated expenses incurred in the normal course of business. These contracts are designated as cash flows hedges. These hedging contracts reduce, but do not entirely eliminate, the impact of adverse foreign exchange rate movements. The Company does not use any of the derivative instruments for trading or speculative purposes. These contracts have maturities of 12 months or less. The Company records changes in the fair value of cash flow hedges in accumulated other comprehensive loss in the condensed consolidated balance sheets, until the forecasted transaction occurs, at which point, the related gain or loss on the cash flow hedge is reclassified to the financial statement line item to which the derivative relates. The amounts reclassified to expenses related to the hedged transactions were immaterial for the periods presented. The fair value of the outstanding non-deliverable foreign currency forward contracts was measured using Level 2 fair value inputs and was immaterial as of March 31, 2021 and September 30, 2020.

Convertible Senior Notes

Convertible Senior Notes	6 Months Ended

Debt Disclosure [Abstract]
Convertible Senior Notes	Convertible Senior Notes In May 2020, the Company issued $172.5 million aggregate principal amount of 2.625% convertible senior notes in a private placement, including $22.5 million which represents the exercise in full of the initial purchasers’ option to purchase additional notes. The net proceeds from the issuance of the Notes was $166.4 million, net of initial purchasers’ discounts and debt issuance costs of $6.1 million. The Company used $40.0 million of the net proceeds to repay in full the debt outstanding under, and terminated the Credit Agreement dated May 4, 2018, as amended, by and among the Company, Wells Fargo, as administrative agent, and the lenders party thereto. The Notes are senior, unsecured obligations of the Company and bear an interest rate of 2.625% per year payable semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2020. The Notes mature on June 1, 2025 unless repurchased, redeemed or converted in accordance with their terms prior to such date. The Notes are convertible into cash, shares of the Company’s common stock or a combination thereof, at the Company’s election, at an initial conversion rate of 30.0044 shares of common stock per $1,000 principal amount of the Notes, which is equal to an initial conversion price of approximately $33.33 per share of common stock subject to adjustment, with a maximum conversion rate of 38.2555. The Company intends to settle the principal amount of the Notes with cash. Prior to the close of business on the scheduled trading day immediately preceding March 1, 2025, holders of the Notes may convert all or a portion of their Notes in multiples of $1,000 principal amount, only under the following circumstances: • during any calendar quarter commencing after the calendar quarter ending on September 30, 2020 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; • during the five five • if the Company calls any or all of the notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or • upon the occurrence of specified corporate events. On or after March 1, 2025 and prior to the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the Notes may convert all or a portion of their Notes in multiples of $1,000 principal amount regardless of the foregoing conditions. Holders of the Notes who convert their Notes in connection with a make-whole fundamental change (as defined in the Indenture) or in connection with any optional redemption are, under certain circumstances, entitled to an increase in the conversion rate. Additionally, in the event of a fundamental change (as defined in the Indenture), holders of the Notes may require the Company to repurchase all or a portion of their Notes at a price equal to 100% of the principal amount of Notes, plus any accrued and unpaid interest to, but excluding, the repurchase date. The Company may not redeem the Notes prior to June 6, 2023. The Company may redeem for cash all or part of the Notes, at its option, on or after June 6, 2023 and on or before the 41st scheduled trading day immediately before the maturity date, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption. No sinking fund is provided for the Notes. During the three months ended March 31, 2021, the conditions allowing holders of the Notes to convert were not met. The Notes were classified as long-term debt on the condensed consolidated balance sheets as of March 31, 2021. In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability component of $115.3 million was calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was $57.2 million and was determined by deducting the fair value of the liability component from the principal amount of the Notes. The excess of the principal amount of the Notes over the carrying amount of the liability component is amortized to interest expense at an effective interest rate over the contractual terms of the Notes. The equity component was recorded in additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the issuance costs related to the Notes, the Company allocated the total amount incurred to the liability and equity components of the Notes based on the proportion of the proceeds allocated to the debt and equity components. Issuance costs attributable to the liability component were $4.1 million and are amortized to interest expense using the effective interest method over the contractual terms of the Notes. Issuance costs attributable to the equity component of $2.0 million were netted with the equity component in stockholders’ equity. The net carrying amounts of the liability and equity components for the Notes were as follows (in thousands): As of As of Liability component: Principal amount $ 172,500 $ 172,500 Unamortized discount (49,605) (54,147) Unamortized issuance costs (3,672) (3,915) Net carrying amount $ 119,223 $ 114,438 Equity component, net of issuance costs $ 55,227 $ 55,227 The following table sets forth the interest expense recognized related to the Notes (in thousands): Three months ended Six months ended March 31, 2021 Coupon interest expense $ 1,132 $ 2,264 Amortization of debt discount 2,302 4,541 Amortization of debt issuance costs 125 243 Total interest expense related to the Notes $ 3,559 $ 7,048 Effective interest rate of the liability component 12.32 % 12.32 % The unamortized debt discount and debt issuance costs will be amortized over 50 months as of March 31, 2021. As of March 31, 2021, the total estimated fair value of the Notes was approximately $223.6 million which includes the equity component. The fair value was determined based on the closing trading price per $100 of the Notes as of the last day of trading for the period. The fair value of the Notes is primarily affected by the trading price of the Company’s common stock and market interest rates. The fair value of the Notes is considered a Level 2 measurement as they are not actively traded.

The income tax provision for the three and six months ended March 31, 2021 was primarily related to foreign taxes on the Company’s profitable foreign operations, foreign withholding taxes on dividends, and deferred taxes on goodwill resulting from the Acquisition. The income tax provision for the three months ended March 31, 2020 was primarily related to foreign taxes on the Company’s profitable foreign operations and foreign withholding taxes on dividends. The income tax provision for the six months ended March 31, 2020 was primarily related to foreign taxes on the Company’s profitable foreign operations and foreign withholding taxes on dividends partially offset by a discrete tax benefit for a true-up in federal income tax payable. The Company elected to partially reinvest foreign earnings in certain foreign jurisdictions and expects to repatriate future foreign earnings in certain foreign jurisdictions over time. As a result, the Company will record a deferred tax liability for the additional non-U.S. taxes that are expected to be incurred related to the repatriation of these earnings. The Company elected to record GILTI as a period cost. The Company realized no benefit for current period losses due to maintaining a full valuation allowance against the U.S. net deferred tax assets.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis for Presentation	Basis for Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated balance sheet as of September 30, 2020 has been derived from the audited financial statements which are included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2020 (“the Annual Report”) on file with the SEC. The unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Annual Report. In the opinion of management, the unaudited interim consolidated financial statements include all the normal recurring adjustments necessary to present fairly our condensed consolidated financial statements. The results of operations for the six months ended March 31, 2021 are not necessarily indicative of the operating results for the full fiscal year 2021 or any future periods. The condensed consolidated financial statements include the accounts of Model N and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates include revenue recognition, liability and equity allocation of convertible senior notes, legal contingencies, income taxes, stock-based compensation and valuation of goodwill and intangibles. These estimates and assumptions are based on management’s best estimates and judgment. Management regularly evaluates its estimates and assumptions using historical experience and other factors. However, actual results could differ significantly from these estimates.
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted Accounting Guidance In August 2018, the FASB issued ASU 2018-15, Intangibles (Topic 350), Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which 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. This standard also requires customers to amortize the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement. ASU 2018-15 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. The Company adopted this guidance in the first quarter of fiscal year 2021 and it did not have a material impact on the condensed consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model which requires the use of forward-looking information to calculate credit loss estimates. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. ASU 2016-13 requires a cumulative effect adjustment to the balance sheet as of the beginning of the first reporting period in which the guidance is effective. The Company adopted this guidance in the first quarter of fiscal year 2021 and it did not have a material impact on the condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes, which simplifies the accounting for incomes taxes by removing certain exceptions to the general principles in Topic 740 and amending existing guidance to improve consistent application. ASU 2019-12 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the impact this standard will have on its condensed consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40), Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. ASU 2020-06 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2021, with early adoption permitted. The Company is currently evaluating the impact this standard will have on its condensed consolidated financial statements. Significant Accounting Policies There have been no changes in the significant accounting policies from those that were disclosed in the audited consolidated financial statements for the fiscal year ended September 30, 2020 included in the Annual Report on Form 10-K.
Revenues from Contract with Customer	Accounts Receivable Accounts receivable represents the Company’s right to consideration that is unconditional, net of allowances for doubtful accounts. The allowance for doubtful accounts is based on management’s assessment of the collectability of accounts receivable amounts. Contract Asset Contract asset represents revenue that has been recognized for satisfied performance obligations for which the Company does not have an unconditional right to consideration. Deferred Revenue Deferred revenue, which is a contract liability, consists of amounts that have been invoiced and for which the Company has the right to bill, but that have not been recognized as revenue because the related goods or services have not been transferred. Capitalized Contract Acquisition Costs The Company capitalizes incremental costs incurred to acquire contracts with customers, primarily sales commissions, for which the associated revenue is expected to be recognized in future periods. The Company incurs these costs in connection with both initial contracts and renewals. Such costs for renewals are not considered commensurate with those for initial contracts given the substantive difference in commission rates in proportion to their respective contract values. The costs in connection with initial contracts and renewals are deferred and amortized over an expected customer life of five years and over the renewal term, respectively, which corresponds to the period of benefit to the customer. The Company determined the period of benefit by considering the Company’s history of customer relationships, length of customer contracts, technological development and obsolescence, and other factors. The current and non-current portion of capitalized contract acquisition costs are included in other current assets and other assets on the condensed consolidated balance sheets. Amortization expense is included in sales and marketing expenses on the condensed consolidated statements of operations. Customer Deposits Customer deposits primarily relate to payments received from customers which could be refundable pursuant to the terms of the related arrangement. These amounts are included in accrued liabilities on the condensed consolidated balance sheets. Customer deposits were immaterial as of March 31, 2021 and September 30, 2020. Standard payment terms to customers generally range from thirty to ninety days; however, payment terms and conditions in our customer contracts may vary. In some cases, customers prepay for subscription and services in advance of the delivery; in other cases, payment is due as services are performed or in arrears following the delivery.
