Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Principles of ConsolidationThe accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with U.S. GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Final Prospectus.
Principles of Consolidation	The accompanying condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiary. All intercompany transactions and balances have been eliminated in consolidation. In the opinion of the Company’s management, the information contained herein reflects all adjustments necessary for a fair presentation of Doximity’s financial position, results of operations, stockholders’ equity, and cash flows. The results of operations for the three and nine months ended December 31, 2021, shown in this report are not necessarily indicative of the results to be expected for the full year ending March 31, 2022.
Reclassification	We reclassified certain prior year amounts, as applicable, to conform to the current year presentation.
Fiscal Year	Fiscal Year The Company’s fiscal year ends on March 31st. Unless otherwise noted, all references to a particular year shall mean the Company’s fiscal year.
Use of Estimates	Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts stated in the condensed consolidated financial statements and accompanying notes. These judgments, estimates, and assumptions are used for, but not limited to, the determination of revenue recognition, fair values of acquired intangible assets and goodwill, useful lives of long-lived assets, internal-use software development costs, the valuation of the Company’s common stock, the valuation of stock-based awards, allowance for doubtful accounts, expected period of benefit for deferred commissions, and deferred income taxes. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. However, future events are subject to change and best estimates and judgments routinely require adjustment. Actual results could differ from those estimates. The World Health Organization declared in March 2020 that the recent outbreak of the coronavirus disease (“COVID-19”) constituted a pandemic. The COVID-19 pandemic has had, and continues to have, a significant impact on the U.S. economy and the markets in which the Company operates. The Company has not experienced significant adverse impacts on its business and workforce and the Company’s results of operations, cash flows, and financial condition have not been adversely impacted to date. The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s results of operations, cash flows, and financial condition will depend on future developments that are highly uncertain and cannot be accurately predicted. As of the date of issuance of the condensed consolidated financial statements, the Company is not aware of any specific event or circumstance that would require it to update its estimates, judgments, or the carrying value of its assets or liabilities. These estimates 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. Actual results could differ from those estimates, and any such differences may be material to the Company’s condensed consolidated financial statements.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, and accounts receivable. The primary focus of the Company’s investment strategy is to preserve capital and meet liquidity requirements. The Company’s investment policy addresses the level of credit exposure by limiting the concentration in any one corporate issuer or sector and establishing a minimum allowable credit rating. To manage risk exposure, the Company invests cash equivalents and marketable securities in a variety of fixed income securities, including government and investment-grade debt securities and money market funds. The Company places its cash primarily in checking and money market accounts with reputable financial institutions. Deposits held with these financial institutions may exceed the amount of insurance provided on such deposits, if any. Concentrations of credit risk with respect to accounts receivable are primarily limited to certain customers to which the Company makes substantial sales. The Company performs ongoing assessments and credit evaluations of its customers to assess the collectability of the accounts receivable based on a number of factors, including past transaction experience, age of the receivable, review of the invoicing terms of the contracts, and recent communications with customers. The Company has not experienced significant credit losses from its accounts receivable.
Stock-Based Compensation	Stock-Based Compensation The Company measures and recognizes compensation expense for all stock-based awards based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. Stock-based awards include stock options with service-based, performance-based and market-based vesting conditions, restricted stock units (“RSUs”), performance-based restricted stock units (“PSUs”) granted to employees, directors, and non-employees, as well as stock purchase rights granted to employees under the Employee Stock Purchase Plan (“ESPP”). For awards that vest based on continued service, stock-based compensation is recognized on a straight-line basis over the requisite service period. For awards with performance-based vesting conditions, stock-based compensation expense is recognized using an accelerated attribution method from the time it is deemed probable that the vesting condition will be met through the time the service-based vesting condition has been achieved. The Company reassesses the probability of achieving the performance condition at each reporting date. For awards with market-based vesting conditions, stock-based compensation expense is recognized on an accelerated attribution basis over the requisite service period, even if the market condition is not satisfied. The grant-date fair value of warrants, stock purchase rights granted to employees under the ESPP, and stock options with service-based or performance-based vesting conditions is estimated using the Black-Scholes pricing model. The grant-date fair value of market-based options is estimated using the Monte Carlo simulation model. The determination of the grant-date fair value using an option-pricing model is affected by the estimated fair value of the Company’s common stock as well as assumptions regarding a number of other complex and subjective variables. These variables include the expected term of the award, the expected stock price volatility over the expected term of the award, the risk-free interest rate for the expected term of the award, and expected dividends. The fair value of each RSU and PSU is based on the fair value of the Company’s common stock on the date of grant. Forfeitures are estimated based upon the Company’s historical experience and the Company revises its estimates, if necessary, in subsequent periods if actual forfeitures differ from initial estimates.
Accounting Pronouncements Recently Adopted and Not Yet Adopted	Accounting Pronouncements Recently Adopted In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, to simplify how entities assess goodwill for impairment by eliminating Step 2 from the goodwill impairment test. As amended, the goodwill impairment test consists of one step comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. This guidance is effective for the Company for its interim and annual period beginning April 1, 2023, and early adoption is permitted. The Company early adopted this new guidance effective April 1, 2021, using a prospective approach. The Company will perform its annual impairment assessment in the fourth quarter of fiscal 2022 under this new guidance. The adoption of this guidance is not expected to have a material impact on the condensed consolidated financial statements. Accounting Pronouncements Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, that simplifies the accounting for income taxes by removing certain exceptions to the general principles in such areas as intraperiod tax allocation, year-to-date losses in interim periods, and deferred tax liabilities related to outside basis differences. Amendments also include simplifications in other areas such as franchise taxes, step-up in tax basis goodwill, separate entity financial statements, and interim recognition of enactment of tax laws or rate changes. This guidance is effective for the Company for its fiscal year beginning April 1, 2022 and interim periods within its fiscal year beginning April 1, 2023. The Company is currently evaluating the impact of the adoption of this guidance on its condensed consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customer, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with Topic 606, Revenue from Contracts with Customers, as if it had originated the contracts. Under the current business combinations guidance, such assets and liabilities are recognized by the acquirer at fair value on the acquisition date. This guidance is effective for the Company for its fiscal year beginning April 1, 2023 and interim periods within that fiscal year, and early adoption is permitted. The Company expects to adopt ASU 2021-08 in the first quarter of fiscal 2023 and expects the adoption to impact the accounting of business combinations, if any, subsequent to the adoption date.
Fair Value Measurements	Fair Value Measurements The Company accounts for fair value in accordance with ASC 820, Fair Value Measurements and Disclosures. Valuation techniques used to ensure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses a three-tier hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1—Inputs that are unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2—Inputs (other than quoted prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities and which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

Use of Estimates

The preparation of the Company’s condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts stated in the condensed consolidated financial statements and accompanying notes. These judgments, estimates, and assumptions are used for, but not limited to, the determination of revenue recognition, fair values of acquired intangible assets and goodwill, useful lives of long-lived assets, internal-use software development costs, the valuation of the Company’s common stock, the valuation of stock-based awards, allowance for doubtful accounts, expected period of benefit for deferred commissions, and deferred income taxes.

Accounting Pronouncements Recently Adopted and Not Yet Adopted

Accounting Pronouncements Recently Adopted

In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, to simplify how entities assess goodwill for impairment by eliminating Step 2 from the goodwill impairment test. As amended, the goodwill impairment test consists of one step comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. This guidance is effective for the Company for its interim and annual period beginning April 1, 2023, and early adoption is permitted. The Company early adopted this new guidance effective April 1, 2021, using a prospective approach. The Company will perform its annual impairment assessment in the fourth quarter of fiscal 2022 under this new guidance. The adoption of this guidance is not expected to have a material impact on the condensed consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, that simplifies the accounting for income taxes by removing certain exceptions to the general principles in such areas as intraperiod tax allocation, year-to-date losses in interim periods, and deferred tax liabilities related to outside basis differences. Amendments also include simplifications in other areas such as franchise taxes, step-up in tax basis goodwill, separate entity financial statements, and interim recognition of enactment of tax laws or rate changes. This guidance is effective for the Company for its fiscal year beginning April 1, 2022 and interim periods within its fiscal year beginning April 1, 2023. The Company is currently evaluating the impact of the adoption of this guidance on its condensed consolidated financial statements.

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customer, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with Topic 606, Revenue from Contracts with Customers, as if it had originated the contracts. Under the current business combinations guidance, such assets and liabilities are recognized by the acquirer at fair value on the acquisition date. This guidance is effective for the Company for its fiscal year beginning April 1, 2023 and interim periods within that fiscal year, and early adoption is permitted. The Company expects to adopt ASU 2021-08 in the first quarter of fiscal 2023 and expects the adoption to impact the accounting of business combinations, if any, subsequent to the adoption date.

Fair Value Measurements

The Company accounts for fair value in accordance with ASC 820, Fair Value Measurements and Disclosures. Valuation techniques used to ensure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses a three-tier hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1—Inputs that are unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2—Inputs (other than quoted prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities and which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.
