Organization Consolidation And Presentation Of Financial Statements [Abstract]
The Company and Significant Accounting Policies and Estimates	1. The Company and Significant Accounting Policies and Estimates Model N, Inc. (Company) was incorporated in Delaware on December 14, 1999. The Company is a provider of revenue management solutions for the life science and technology industries. The Company’s solutions 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 Redwood City, California, with additional offices in the United States, India, the United Kingdom and Switzerland. Fiscal Year The Company’s fiscal year ends on September 30. References to fiscal year 2016, for example, refer to the fiscal year ending September 30, 2016. 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 financial statements should be read in conjunction with the consolidated financial statements and notes included in the Annual Report on Form 10-K for the fiscal year ended , 2015. Annual Report on Form 10-K In the opinion of management, the unaudited interim consolidated financial statements include all the normal recurring adjustments necessary to present fairly the condensed consolidated financial statements. The results of operations for the three and six months ended March 31, 2016 were not necessarily indicative of the operating results for the full fiscal year 2016 or any future periods. The Company’s condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant 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, legal contingencies, income taxes, stock-based compensation, software development costs and valuation of 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 In May 2014, the Financial Accounting Standard Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers, which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount to which an entity expects to be entitled when products and services are transferred to customers. ASU 2014-09 was originally to be effective for the Company on October 1, 2017. In July 2015, the FASB affirmed a one-year deferral of the effective date of the new revenue standard. The standard will be effective for our fiscal year beginning October 1, 2018, at which time we may adopt the new standard under either the full retrospective method or the modified retrospective method. Early adoption is permitted. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements and have not determined whether the effect will be material. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The new standard eliminates the requirement for an acquirer to retrospectively adjust provisional amounts recorded in a business combination to reflect new information about the facts and circumstances that existed as of the acquisition date and that, if known, would have affected measurement or recognition of amounts initially recognized. As an alternative, the standard requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. It requires that the acquirer record, in the financial statements of the period in which adjustments to provisional amounts are determined, the effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The new standard is effective prospectively for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of this ASU on the consolidated financial statements. In February 2016, the FASB issued guidance on the recognition and measurement of leases. Under the new guidance, lessees are required to recognize a lease liability, which represents the discounted obligation to make future minimum lease payments, and a corresponding right-of-use asset on the balance sheet for most leases. The guidance retains the current accounting for lessors and does not make significant changes to the recognition, measurement, and presentation of expenses and cash flows by a lessee. Enhanced disclosures will also be required to give financial statement users the ability to assess the amount, timing and uncertainty of cash flows arising from leases. The guidance will require modified retrospective application at the beginning of our first quarter of fiscal 2020, with optional practical expedients, but permits adoption in an earlier period. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In March 2016, the Financial Accounting Standards Board (“FASB”) issued guidance related to stock-based compensation, which changes the accounting for and classification of excess tax benefits and minimum tax withholdings on share-based awards. The guidance becomes effective for us at the beginning of our first quarter of fiscal 2018 but permits adoption in an earlier period. We are currently evaluating the impact this guidance will have on our consolidated financial statements.

Business Combinations [Abstract]
Business Combinations	2. Business Combinations On October 30, 2015, the Company acquired certain assets and liabilities of Channelinsight Inc. (CI), a privately held cloud-based channel data management solution provider. The Company paid a total purchase price of $12.6 million in cash. Pro forma results have not been presented as the Company does not consider the acquisition to be significant. The purchase consideration was allocated to tangible, identifiable intangible assets acquired and liabilities assumed based on their respective fair values as of the acquisition date. This allocation resulted in provisional fair value allocated to intangible assets of $6.8 million and goodwill of $5.4 million. The goodwill is deductible for tax purposes. Intangible assets acquired included developed technology, backlog, patents, trade names and customer relationships, and are being amortized on a straight-line basis over their estimated useful lives of 1 to 10 years. The key factors attributable to the creation of goodwill by the transaction are synergies in skill-sets, operations, customer base and organizational cultures. The results of operations and the provisional fair values of the assets acquired and liabilities assumed have been included in the accompanying unaudited condensed financial statements since the acquisition date.

The Company’s Level 1 assets consist of U.S. treasury bills and money market funds. These instruments are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets.

Income Taxes	7. Income Taxes The Company recorded an income tax expense of $29,000 and $192,000, representing effective income tax rates of (0.3)% and (4)%, for the three months ended March 31, 2016 and 2015, respectively; and $119,000 and $327,000, representing income rates of (0.7)% and (4)%, for the six months ended March 31, 2016 and 2015, respectively. The Company’s effective income-tax rates during these periods differ from the Company’s federal statutory rate of 34% primarily due to permanent differences for stock-based compensation and the impact of state income taxes and foreign tax rate differences, and the Company realized no benefit for current period losses due to maintaining a full valuation allowance against the U.S. and foreign net deferred tax assets.

The lawsuits were brought by purported stockholders of the Company seeking to represent a class consisting of all those who purchased the Company’s stock pursuant and/or traceable to the Registration Statement and Prospectus issued in connection with the IPO. The lawsuits assert claims under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933 and seek unspecified damages and other relief.

The results of operations for the three and six months ended March 31, 2016 were not necessarily indicative of the operating results for the full fiscal year 2016 or any future periods. The Company’s condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant 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, legal contingencies, income taxes, stock-based compensation, software development costs and valuation of 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 In May 2014, the Financial Accounting Standard Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers, which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount to which an entity expects to be entitled when products and services are transferred to customers. ASU 2014-09 was originally to be effective for the Company on October 1, 2017. In July 2015, the FASB affirmed a one-year deferral of the effective date of the new revenue standard. The standard will be effective for our fiscal year beginning October 1, 2018, at which time we may adopt the new standard under either the full retrospective method or the modified retrospective method. Early adoption is permitted. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements and have not determined whether the effect will be material. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The new standard eliminates the requirement for an acquirer to retrospectively adjust provisional amounts recorded in a business combination to reflect new information about the facts and circumstances that existed as of the acquisition date and that, if known, would have affected measurement or recognition of amounts initially recognized. As an alternative, the standard requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. It requires that the acquirer record, in the financial statements of the period in which adjustments to provisional amounts are determined, the effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The new standard is effective prospectively for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of this ASU on the consolidated financial statements. In February 2016, the FASB issued guidance on the recognition and measurement of leases. Under the new guidance, lessees are required to recognize a lease liability, which represents the discounted obligation to make future minimum lease payments, and a corresponding right-of-use asset on the balance sheet for most leases. The guidance retains the current accounting for lessors and does not make significant changes to the recognition, measurement, and presentation of expenses and cash flows by a lessee. Enhanced disclosures will also be required to give financial statement users the ability to assess the amount, timing and uncertainty of cash flows arising from leases. The guidance will require modified retrospective application at the beginning of our first quarter of fiscal 2020, with optional practical expedients, but permits adoption in an earlier period. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In March 2016, the Financial Accounting Standards Board (“FASB”) issued guidance related to stock-based compensation, which changes the accounting for and classification of excess tax benefits and minimum tax withholdings on share-based awards. The guidance becomes effective for us at the beginning of our first quarter of fiscal 2018 but permits adoption in an earlier period. We are currently evaluating the impact this guidance will have on our consolidated financial statements.
Fair Value of Financial Instruments	The financial instruments of the Company consist primarily of cash and cash equivalents, accounts receivable, accounts payable and certain accrued liabilities Fair value is defined as the exchange price that Level 1— Unadjusted in active markets for identical assets or liabilities; Level 2—Input other than quoted prices included in Level 1 that are observable, unadjusted quoted prices in markets that are not active, or other inputs for similar assets and liabilities that are observable or can be corroborated by observable market data; and Level 3—Unobservable inputs that are supported by little or no market activity, which requires the Company to develop its own models and involves some level of management estimation and judgment. The Company’s Level 1 assets consist of U.S. treasury bills and money market funds. These instruments are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets.
