Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	NOTE 2—Basis of Presentation and Significant Accounting Policies
	Principles of Consolidation
	The consolidated financial statements include the accounts of Ellie Mae and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
	Certain adjustments primarily related to the Company’s tax provision for the year ended December 31, 2013 have been made as further described in Note 2, under “Correction of Immaterial Errors.” In addition, certain amounts in prior periods have been reclassified to conform to current period presentation, with no effect on previously reported net income or stockholders’ equity.
	Applicable Accounting Guidance
	Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative generally accepted accounting principles in the United States (“U.S. GAAP”), as found in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”).
	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 and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management evaluates estimates on a regular basis including those relating to revenue recognition, the allowance for doubtful accounts, goodwill, intangible assets, the valuation of deferred income taxes, stock-based compensation and unrecognized tax benefits, among others. Actual results could differ from those estimates and such differences may have a material impact on the Company’s consolidated financial statements and footnotes.
	Cash and Cash Equivalents
	All highly liquid investments with original maturities of 90 days or less are considered to be cash equivalents. Cash equivalents are recorded at cost, which approximates fair value.
	Fair Value of Financial Instruments
	The fair values of the Company’s cash equivalents, accounts receivable and accounts payable approximate their carrying values due to the short maturities of the instruments. The fair value of the Company’s capital lease obligations approximates the carrying value due to the terms continuing to approximate prevailing market terms.
	All of the Company’s investments that have maturities of greater than 90 days are classified as available-for-sale and are carried at fair value. The Company invests excess cash primarily in investment-grade interest-bearing securities, such as money market accounts, certificates of deposit, commercial paper, corporate bonds, municipal and government agency obligations and guaranteed obligations of the U.S. government. Fair value is determined based on quoted market rates when observable or utilizing data points that are observable, such as quoted prices, interest rates and yield curves. The cost of available-for-sale marketable securities sold is based on the specific identification method. Unrealized gains and losses are reported in stockholders’ equity as accumulated other comprehensive (income) loss. Realized gains and losses are included in other income (expense), net. Interest and dividends are included in other income (expense), net when they are earned.
	Accounts Receivable and Allowance for Doubtful Accounts
	Trade accounts receivable consist of amounts billed to customers in connection with sales of services. The Company analyzes individual trade accounts receivable by considering historical bad debts, customer creditworthiness, current economic trends, changes in customer payment terms and collection trends when evaluating the adequacy of the allowance for doubtful accounts. Allowances for doubtful accounts are recognized in the period in which the associated receivable balance is not considered recoverable. Any change in the assumptions used in analyzing accounts receivable may result in changes to the allowance for doubtful accounts and is recognized in the period in which the change occurs. The Company writes off a receivable when all rights, remedies and recourses against the account and its principals are exhausted and records a benefit when previously reserved accounts are collected.
	Concentration of Credit Risk
	The financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments and accounts receivable. The Company’s cash and cash equivalents are deposited with major financial institutions in the United States. At times, such deposits may be in excess of federally insured limits. Management believes that the Company’s investments in cash equivalents and available-for-sale investments are financially sound. The Company’s accounts receivable are derived from revenue earned from customers located in the United States. The Company had no customers that represented 10% or more of revenues for the years ended December 31, 2014, 2013 and 2012. No customer represented more than 10% of accounts receivable as of December 31, 2014 and 2013.
	Software and Website Development Costs
	The Company capitalizes internal and external costs incurred to develop internal-use software and website applications. Capitalized internal costs include salaries, benefits and stock-based compensation charges for employees that are directly involved in developing the software or website application, and depreciation of assets used in the development process. Capitalized external costs include third-party consultants involved in the development process, as well as other direct costs incurred as part of the development process.
	Capitalization of costs begins when the preliminary project stage has been completed, management authorizes and commits to funding a project and it is probable that the project will be completed and the software or website application will be used to perform the function intended. Internal and external costs incurred as part of the preliminary project stage are expensed as incurred.
	Capitalization ceases at the point at which the project is substantially complete and ready for its intended use. Internal and external training costs and maintenance costs during the post-implementation operation stage are expensed as incurred.
	Internal-developed core software is amortized on a straight-line basis over its estimated useful life, generally three to five years. Amortization of product related internal-use software and website applications is typically recorded to cost of revenues, and amortization of other internal-use software and website applications is typically recorded to the operating expense line to which it most closely relates. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. The capitalized costs are included in property and equipment, net in the accompanying consolidated balance sheets. For the years ended December 31, 2014, 2013 and 2012, the Company capitalized software and website application development costs of $15.9 million, $5.1 million, and $0.5 million, respectively.
	During the year ended December 31, 2014, the Company recorded a $0.7 million impairment loss on the write-off of internal-use software. There were no such write-offs during the years ended December 31, 2013 and 2012.
	Property and Equipment
	Property and equipment are stated at cost less accumulated depreciation and are depreciated on a straight-line basis over their estimated useful lives, which is generally three to seven years. Leasehold improvements are amortized on a straight-line basis over their estimated useful lives or over the term of the lease, whichever is shorter.
	Business Combinations
	The Company recognizes and measures the identifiable assets acquired in a business combination, the liabilities assumed and any non-controlling interest in the acquiree, measured at their fair values as of the acquisition date. The Company recognizes contingent consideration arrangements at their acquisition-date fair values with subsequent changes in fair value reflected in earnings, recognizes pre-acquisition loss and gain contingencies at their acquisition-date fair values (with certain exceptions), capitalizes in-process research and development assets and expenses acquisition-related transaction costs as incurred. Due to the inherent uncertainty in the Company’s best estimates and assumptions, they are subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of assets acquired and liabilities assumed, with the corresponding offset to goodwill. Any subsequent adjustments, including changes in accounting for deferred tax asset valuation allowances and acquired income tax uncertainties after the measurement period, are recognized in earnings rather than as an adjustment to the cost of the acquisition.
	Goodwill
	The Company records goodwill in a business combination when the consideration paid exceeds the fair value of the net assets acquired. Goodwill is not amortized, but is tested for impairment at least annually in the fourth quarter of the Company’s fiscal year, or whenever changes in circumstances indicate that the fair value of a reporting unit is less than its carrying amount, including goodwill. The annual test is performed at the reporting unit level using a fair-value based approach. The Company’s operations are organized as one reporting unit. In testing for a potential impairment of goodwill, the Company first compares the carrying value of assets and liabilities to the estimated fair value. If estimated fair value is less than carrying value, then potential impairment exists. The amount of any impairment is then calculated by determining the implied fair value of goodwill using a hypothetical purchase price allocation. Impairment is equivalent to any excess of goodwill carrying value over its implied fair value. There were no impairment charges related to goodwill during the years ended December 31, 2014, 2013, and 2012.
	The process of evaluating the potential impairment of goodwill requires significant judgment at many points during the analysis, including calculating fair value of the reporting unit based on estimated future cash flows and discount rates to be applied.
	Intangible Assets
	Intangible assets are stated at cost less accumulated amortization. Intangible assets include developed technology, trade names and customer lists and contracts. Intangible assets with finite lives are amortized on a straight-line basis over the estimated periods of benefit, as follows:
	Developed technology	2-5 years
	Trade names with finite lives	2-3 years
	Customer lists and contracts	4-9 years
	Intangible assets with indefinite useful lives, including the AllRegs trade name, are stated at cost. The Company evaluates the remaining useful life of indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support an indefinite useful life.
	The Company evaluates its finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset or asset group to future undiscounted net cash flows expected to be generated by the asset or asset group. If such assets or asset groups are considered to be impaired, the impairment loss to be recognized is measured by the amount by which the carrying amounts of the assets or asset groups exceed the fair value of the assets or asset groups. Assets to be disposed of are reported at the lower of the carrying amount and fair value less costs to sell. Except as described in Note 6, there has been no loss on impairment or disposal of intangible assets.
	Impairment of Long-Lived Assets
	The Company evaluates its long-lived assets for indications of possible impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Except for the impairment losses recorded on internal-use software and intangible assets described elsewhere in this note, there has been no loss on impairment or disposal of long-lived assets.
	Revenue Recognition
	The Company generates revenues primarily from transaction-based fees and fees for software and related services. On-demand revenues are revenues generated from company-hosted software subscriptions that customers access through the Internet and revenues from customers that pay fees based on a per closed loan, or success, basis subject to monthly base fees, which the Company refers to as Success-Based Pricing. Additionally, on-demand revenues are comprised of software services sold transactionally; Ellie Mae Network transaction fees; education and training, loan product and guideline data and analytics services under the AllRegs brand; and professional services which include consulting, implementation and training services. On-premise revenues are revenues generated from maintenance services, sales of customer-hosted software licenses, and professional services. Sales taxes assessed by governmental authorities are excluded from revenue.
	The Company commences revenue recognition when all of the following conditions are satisfied:
	•There is persuasive evidence of an arrangement;
	•The service has been or is being provided to the customer;
	•The collection of the fees is reasonably assured; and
	•The amount of fees to be paid by the customer is fixed or determinable.
	On-Demand Revenues
	Subscription Services and Usage-Based Fee Arrangements. Subscription services and usage-based fee arrangements generally include a combination of the Company’s products delivered as software-as-a-service (“SaaS”) and support services. These arrangements are generally non-cancelable and do not contain refund-type provisions. These revenues typically include the following:
	SaaS Encompass Revenues. The Company offers web-based, on-demand access to Encompass software for a monthly recurring fee. The Company provides the right to access its loan origination software and handles the responsibility of managing the servers, providing security, backing up the data and applying updates. Customers under SaaS arrangements may not take possession of the software at any time during the term of the agreement. Subscription revenues are recognized ratably over the contract terms as subscription services are provided, beginning on the commencement date of each contract, which is the date the Company’s service is made available to customers. Contracts generally range from one year to five years.
	Alternatively, customers can elect to pay on a success basis. Success basis contracts generally have a term of one to five years and are subject to monthly base fees, which enable customers to close loans up to a contractually agreed-to minimum number of transactions, and additional closed loan fees, which are assessed for loans closed in excess of the minimum. Revenue is earned from both base fees and additional closed loan fees as the result of the customer’s usage of Encompass. Monthly base fees are recognized over the respective monthly service period as the subscription services are provided. Additional closed loans fees are recognized when the loans are reported as closed. This offering also includes Encompass CenterWise, Encompass Compliance Service and Encompass Docs Solution as integrated components, which are combined elements of the arrangement that are delivered in conjunction with the SaaS Encompass offering and therefore are not accounted for separately.
	Encompass CenterWise Revenues. Encompass CenterWise is a bundled offering of electronic document management (“EDM”) and websites used for customer relationship management. Generally, revenue is recognized for Encompass CenterWise after the service is rendered, except when Encompass CenterWise is automatically included as an integrated component of the SaaS Encompass offering, in which case the associated revenue is recognized as described above.
	Services Revenues. The Company provides a variety of mortgage-related and other business services, including automated documentation; fraud detection, valuation, validation and risk analysis; income verification; marketing and customer management; flood zone certifications; and compliance reports. Services revenues are recognized upon completion of the services.
	Transactional Revenues. The Company has entered into agreements with various lenders, service providers and certain government-sponsored entities participating in the mortgage origination process that provide them access to, and ability to interoperate with, mortgage originators on the Ellie Mae Network. Under these agreements, the Company earns transaction fees when transactions are processed through the Ellie Mae Network. Transaction revenues are recognized when there is evidence that the qualifying transactions have occurred on the Ellie Mae Network and collection of the resulting receivable is reasonably assured.
	Subscriptions to Online Research and Data Resources: The Company provides mortgage originators and underwriters with access to online databases of various federal and state laws and regulations and forms as well as mortgage investor product guidelines. Subscription fees are recognized ratably over the subscription term as subscription services are provided, which is typically one year.
	Professional Services Revenues: Professional services revenues are generally recognized when milestones are achieved for fixed price contracts or as the services are rendered for time and material contracts. The majority of our professional services contracts are on fixed price basis. Training revenues are recognized as the services are rendered.
	On-Premise Revenues
	Revenue from the sale of software licenses is recognized in the month in which the required revenue recognition criteria are met, generally in the month in which the software is delivered. Revenue from the sale of maintenance services and professional services is recognized over the period in which the services are provided.
	Multiple Element Arrangements
	The Company has entered into both subscription services and software arrangements with multiple elements. For arrangements with multiple deliverables, the Company evaluates whether the individual deliverables qualify as separate units of accounting. In order to treat deliverables in a multiple-deliverable arrangement as separate units of accounting, the deliverables must have standalone value upon delivery.
	Subscription services agreements with multiple elements generally include multiple subscriptions and professional services. When such agreements involve multiple elements that qualify as separate units of accounting, the Company allocates arrangement consideration to all deliverables at the inception of an arrangement based on the relative selling price method in accordance with the selling price hierarchy, which includes: (i) vendor specific objective evidence (“VSOE”) if it is available; (ii) third-party evidence (“TPE”) if VSOE is not available; and (iii) the best estimate of selling price (“BESP”) if neither VSOE nor TPE is available.
	VSOE. The Company determines VSOE based on its historical pricing and discounting practices for the specific product or service when sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices for these services fall within a reasonably narrow pricing range. The Company has not historically priced its subscription services within a narrow range. As a result, the Company has not been able to establish selling prices for subscription services based on VSOE.
	TPE. When VSOE cannot be established for deliverables in multiple element arrangements, the Company applies judgment with respect to whether it can establish a selling price based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, the Company’s go-to-market strategy differs from that of its peers and its offerings contain a significant level of differentiation such that the comparable pricing of services with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor services’ selling prices are on a standalone basis. As a result, the Company has not been able to establish selling prices based on TPE.
	BESP. When the Company is unable to establish a selling price using VSOE or TPE, the Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the service was sold on a standalone basis. When establishing BESP, the Company reviews company specific factors used to determine list price and makes adjustments as appropriate to reflect current market conditions and pricing behavior. The Company’s process for establishing list price includes assessing the cost to provide a particular product or service, surveying customers to determine market expectations, analyzing customer demographics and taking into account similar products and services historically sold by the Company. The Company continues to review the factors used to establish list price and adjusts BESP as necessary.
	Because the Company has determined that neither VSOE nor TPE is available, it uses BESP to allocate the selling price to multiple elements in subscription services arrangements. The amount of revenue allocated to delivered items is limited by contingent revenue, if any.
Subscription services have standalone value as such services are often sold separately. Additionally, the Company has concluded that professional services included in multiple element arrangements have standalone value. In establishing standalone value, the Company considered the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, and the timing of when the professional services contract was signed in comparison to the subscription service start date.
For software arrangements with multiple elements (e.g., maintenance and support contracts bundled with licenses), revenue is allocated to the delivered elements of the arrangement when VSOE is determinable, using the residual value method based on objective evidence of the fair value of the undelivered elements, which is specific to the Company. When VSOE is not determinable, the entire arrangement is recognized ratably over the term of the contract. Revenue is recognized under this model upon receipt of cash payment from the customer if collectability is not reasonably assured and when other revenue recognition criteria have been met. The VSOE of fair value for maintenance and support obligations related to licenses is based upon the prices paid for the separate renewal of these services by customers. Maintenance revenues are recognized ratably over the period of the maintenance contract.
Deferred Revenue
Deferred revenue represents billings or payments received in advance of revenue recognition and is recognized as the revenue recognition criteria are met. Balances consist primarily of prepaid subscription services and professional, training and maintenance services not yet provided as of the balance sheet date. Deferred revenue that will be recognized during the succeeding 12 month period is recorded as current deferred revenue, and the remaining portion is recorded as other long-term liabilities. Long-term deferred revenue at December 31, 2014 and 2013 was not material.
Deferred Commission Expense
Deferred commission expenses are the incremental costs that are directly associated with non-cancelable subscription contracts with customers and consist of sales commissions paid to our direct sales force. Commissions are calculated based on a percentage of the revenues for the non-cancelable term of subscription contracts, which are typically one to five years.
Prior to 2013, commissions were paid and recognized as sales expense when customer payments for contracted services were received on a monthly basis because commissions were earned based on receipt of customer payments. In 2013, the Company amended its commission plans to provide for payment after the customer’s contract is signed. As a result of the change in commission plans, beginning in 2013, commission expense was deferred and amortized to sales expense over the non-cancelable terms of the related subscription contracts. The deferred commission expense amounts are recoverable through the future revenue streams under the non-cancelable customer contracts. The plans also include claw back provisions, which require repayment of a proportionate amount of commissions, should customers cancel their contracts prior to the end of the initial contractual term.
During the years ended December 31, 2014 and 2013, the Company deferred $2.5 million and $1.9 million of commission expense, respectively. No amounts were deferred during the year ended December 31, 2012.
At December 31, 2014 and 2013, $3.3 million and $1.6 million of deferred commission remained on our consolidated balance sheets, respectively.
Warranties and Indemnification
The Company provides a warranty for its software products and services to its customers and accounts for its warranties as a contingent liability. The Company’s software is generally warranted to perform substantially as described in the associated product documentation and to satisfy defined levels of uptime reliability. The Company’s services are generally warranted to be performed consistent with industry standards. The Company has not provided for a warranty accrual as of December 31, 2014 or 2013. To date, the Company’s product warranty expense has not been significant.
The Company generally agrees to indemnify its customers against legal claims that the Company’s software products infringe certain third-party intellectual property rights and accounts for its indemnification obligations as a contingent liability. In addition, the Company may also incur liability under its contracts if it breaches its warranties as well as certain security and/or confidentiality obligations. To date, the Company has not been required to make any payment resulting from either infringement claims asserted against its customers or from claims in connection with a breach of the security and/or confidentiality obligations in the Company’s contracts. The Company has not recorded a liability for related costs as of December 31, 2014 or 2013.
The Company has obligations under certain circumstances to indemnify each member of the Company’s board of directors against judgments, fines, settlements and expenses related to claims against such directors and otherwise to the fullest extent permitted under Delaware law and the Company’s bylaws and certificate of incorporation.
Cost of Revenues
The Company’s cost of revenues consists primarily of salaries, benefits and related costs (including stock-based compensation), allocated facilities costs, customer support, data centers, expenses for document preparation, income verification and compliance services, depreciation on computer equipment used in supporting the Ellie Mae Network, the Company’s SaaS Encompass and Encompass CenterWise offerings, amortization of acquired intangible assets and capitalized internal-use software and website applications directly involved in revenue producing activities and professional services associated with implementation of software.
Research and Development Costs
The Company’s research and development expenses consist primarily of: salaries and benefits, including bonuses and stock-based compensation expense; fees to contractors engaged in the development and support of the Ellie Mae Network, Encompass software and other products; and allocated facilities costs. Research and development costs that are not capitalized as internal-use software are expensed as they are incurred.
Advertising Expenses
The Company expenses advertising costs as incurred. Advertising expenses for the years ended December 31, 2014, 2013 and 2012 were $0.4 million, $0.4 million, and $0.3 million, respectively.
Stock-Based Compensation
The Company recognizes stock-based compensation related to awards granted under its 2009 Stock Option and Incentive Plan (the “2009 Plan”), 2011 Equity Incentive Award Plan (the “2011 Plan”) and Employee Stock Purchase Plan (“ESPP”).
The Company recognizes compensation expense related to stock option grants that are ultimately expected to vest based on estimated fair values on the date of grant using the Black-Scholes option-pricing model. Such expense is recognized on a straight-line basis over the requisite service period of the award, which generally equals the vesting period.
The Company recognizes compensation expense related to restricted awards, restricted stock unit awards (“RSUs”), and performance share awards (“Performance Awards”) based on the fair market value of the underlying shares of common stock as of the date of grant. Expense related to the restricted awards and the RSUs are recognized on a straight-line basis over the requisite service period of the award, which generally equals the vesting period. Expense related to the Performance Awards is recognized under the graded vesting method over the requisite service period of the award, which recognizes a larger portion of the expense during the beginning of the vesting period than in the end of the vesting period. Management estimates the probable number of shares of common stock that will be granted until the achievement of the performance goals is known.
The date of grant is the date at which the Company and the employee reach a mutual understanding of the key terms and conditions of the award, appropriate approvals are received by approval by the board of directors and the Company becomes contingently obligated to issue equity instruments to the employee who renders the requisite service.
The Company is required to estimate potential forfeitures of stock grants and adjust recorded compensation cost accordingly. The estimate of forfeitures is based on historical experience and is adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from the prior estimates. Changes in estimated forfeitures will be recognized in the period of change and will impact the amount of stock-based compensation expense to be recognized in future periods.
All stock option awards to non-employees are accounted for at the fair value of the consideration received or the fair value of the equity instrument issued, as calculated using the Black-Scholes option-pricing model. The measurement of stock-based compensation for non-employees is subject to periodic adjustments as the options vest, and the expense is recognized over the period services are rendered.
Other Income (Expense), Net
Other income, net consisted of the following:
	Year ended December 31,
	2014			2013			2012
	(in thousands)
Interest income	556			650			146
Net realized gain (loss) on investments	1			(55	)		—
Interest expense	(69	)		(135	)		(189	)
Total other income (expense), net	488			460			(43	)
Income Taxes
The Company accounts for income taxes under the asset and liability method, which requires the recognition of taxes payable or refundable for the current year, and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. The measurement of current and deferred tax liabilities and assets is based on provisions of the enacted tax law; the effects of future changes in tax laws or rates are not anticipated. Valuation allowances are established when necessary to reduce deferred tax assets to the amount that the Company believes is more likely than not to be realized. The Company’s determination of its valuation allowance is based upon a number of assumptions, judgments and estimates, including forecasted earnings, future taxable income and the relative proportions of revenue and income before taxes in the various jurisdictions in which it operates.
The Company operates in various tax jurisdictions and is subject to audit by various tax authorities. Tax positions are based upon their technical merits, relevant tax law and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax positions. A tax position is only recognized in the financial statements if it is “more likely than not” to be sustained based solely on its technical merits as of the reporting date. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments that could result in recognition of additional tax benefits or additional charges to the tax provision and may not accurately reflect actual outcomes. The Company has a policy to classify accrued interest and penalties associated with uncertain tax positions together with the related liability, and the expenses incurred related to such accruals are included in the provision for income taxes.
Comprehensive Income
Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes certain changes in equity that are excluded from net income, specifically unrealized gains (losses) on available-for-sale investments. Except for net realized loss on investments which was not significant, there were no reclassifications out of accumulated other comprehensive income (loss) that affected net income during the years ended December 31, 2014 and 2013.
Geographical Information
The Company is domiciled in the United States and had no international operations or sales to customers outside of the United States for the years ended December 31, 2014, 2013 and 2012.
Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 also requires significantly expanded disclosures about revenue recognition. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”), which provides guidance on determining when and how reporting entities must disclose going-concern uncertainties in their financial statements. ASU 2014-15 requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date of issuance of the entity’s financial statements (or within one year after the date on which the financial statements are available to be issued, when applicable). Further, an entity must provide certain disclosures if there is “substantial doubt about the entity’s ability to continue as a going concern.” ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods thereafter; early adoption is permitted. The Company does not believe that adoption of ASU 2014-15 will have a material impact on its consolidated financial statements.
Correction of Immaterial Errors
During 2013 and the first three quarters of 2014, in preparing its quarterly and annual tax provisions, the Company incorrectly excluded a portion of compensation to the Company’s executive officers as nondeductible for income tax purposes under Section 162(m) of the Internal Revenue Code. During the fourth quarter of 2014, management determined that such compensation was, in fact, deductible and should have been included in the computation of the Company’s historical income tax computations. The Company assessed the materiality of this misstatement on prior periods’ financial statements in accordance with SEC’s Staff Accounting Bulletin ("SAB") No. 99, Materiality, codified in ASC 250, ("ASC 250"), Presentation of Financial Statements, and concluded that the misstatement was not material to any prior annual or interim periods, but the cumulative adjustment necessary to correct the classification would be material to the three months ended December 31, 2014. In accordance with ASC 250 (SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements), the financial statements as of December 31, 2013 and for the year ended December 31, 2013, which are presented herein, have been corrected. The financial statements have also been revised to reflect the correction of certain other previously uncorrected immaterial prior period errors.
The following tables summarize the previously reported and corrected amounts of the impacted balances presented in the accompanying consolidated financial statements (in thousands except per share data).

Earnings Per Share [Abstract]
Net Income Per Share of Common Stock	Net Income Per Share of Common Stock
	Net income per share of common stock is calculated by dividing net income by the weighted average shares of common stock outstanding during the period. Diluted net income per share of common stock is calculated by dividing net income by the weighted average shares of common stock outstanding and potential shares of common stock during the period. Potential shares of common stock include dilutive shares attributable to the assumed exercise of stock options, RSUs, performance share awards (“Performance Awards”) and Employee Stock Purchase Plan (“ESPP”) shares using the treasury stock method, if dilutive.
	The components of net income per share of common stock were as follows:
		Year ended December 31,
		2014			2013			2012
		(in thousands, except share and per share amounts)
	Net income	$	14,823		$	13,318		$	19,464
	Basic shares:
	Weighted average common shares outstanding	27,858,828			26,581,962			23,523,222
	Diluted shares:
	Weighted average shares used to compute basic net income per share	27,858,828			26,581,962			23,523,222
	Effect of potentially dilutive securities:
	Employee stock options, RSUs, Performance Awards and ESPP shares	1,735,045			1,920,441			2,013,970
	Weighted average shares used to compute diluted net income per share	29,593,873			28,502,403			25,537,192
	Net income per share:
	Basic	$	0.53		$	0.5		$	0.83
	Diluted	$	0.5		$	0.47		$	0.76
	The following potential common shares were excluded from the computation of diluted net income per share, as their effect would have been anti-dilutive:
		Year ended December 31,
		2014		2013			2012
	Employee stock options and awards	624,277		758,900			252,462
	Performance Awards are included in the diluted shares outstanding for each period if the established performance criteria have been met at the end of the respective periods. However, if none of the required performance criteria have been met for such awards, the Company includes the number of shares that would be issuable if the end of the reporting period were the end of the contingency period. Accordingly, in addition to the shares noted above, 588,000 Performance Awards were excluded from the dilutive shares outstanding for the year ended December 31, 2012. No shares were excluded from the dilutive shares outstanding for the years ended December 31, 2014 or 2013.

Financial Instruments and Fair Value Measurements [Abstract]
Financial Instruments and Fair Value Measurements	NOTE 4—Financial Instruments and Fair Value Measurements
	Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are classified and disclosed in one of the following three categories:
	Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities.
	Level 2 — Valuations based on other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 — Valuations based on inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the assets or liabilities.
	The following tables set forth by level within the fair value hierarchy the Company’s financial assets that were accounted for at fair value on a recurring basis, according to the valuation techniques the Company used to determine their values:
		Fair value at		Fair value measurements

	Financial instruments include cash, cash equivalents and investments including investment-grade interest-bearing securities, such as money market accounts, certificates of deposit, commercial paper, corporate bonds, municipal and government agency obligations and guaranteed obligations of the U.S. government. The Company classifies its money market funds that are specifically backed by debt securities and U.S. government obligations as Level 1 instruments due to the use of observable market prices for identical securities that are traded in active markets.
	When the Company uses observable market prices for identical securities that are traded in less active markets, the Company classifies its marketable financial instruments as Level 2. When observable market prices for identical securities are not available, the Company prices its marketable financial instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on the proprietary valuation models of pricing providers. These valuation models incorporate a number of inputs, including non-binding and binding broker quotes; observable market prices for identical or similar securities; and the internal assumptions of pricing providers or brokers that use observable market inputs and, to a lesser degree, unobservable market inputs. The Company corroborates non-binding market consensus prices with observable market data as such data exists.
	As of December 31, 2014 and December 31, 2013, the Company did not have any assets or liabilities that were valued using Level 3 inputs. For the years ended December 31, 2014, 2013 and 2012, there were no transfers of financial instruments between Level 1, Level 2 or Level 3 classifications.
	For the years ended December 31, 2014, 2013 and 2012, the Company recognized interest income from financial instruments of $0.6 million, $0.7 million and $0.1 million, respectively. Gross realized gains and gross realized losses from the sale of investments were not significant during the years ended December 31, 2014, 2013 and 2012.

Business Combinations [Abstract]
Acquisitions	Acquisitions
	MortgageCEO
	On January 15, 2014, the Company acquired substantially all the assets of ARG Interactive, LLC (dba MortgageCEO) (“MortgageCEO”), a SaaS company specializing in customer relationship management and marketing solutions for the residential mortgage industry. The Company acquired the MortgageCEO business in order to add functionality to its product offerings. The transaction was accounted for as a business combination and, accordingly, the total purchase price was allocated to the assets acquired based on their respective fair values. The Company expensed all transaction costs, which were insignificant, in the period in which they were incurred.
	The total purchase consideration was $5.0 million in cash, of which $4.5 million was paid at the time of closing. The remaining $0.5 million (the “holdback funds”) has been retained from the purchase consideration to cover working capital adjustments and any indemnity claims. Any unused portion of the holdback funds will be paid on July 15, 2015. The liability associated with the holdback funds is recorded to Acquisition holdback, net of discount in the Balance Sheet.
	The allocation of the consideration of $5.0 million to the identifiable tangible and intangible assets acquired and liabilities assumed under the purchase method of accounting, based on their estimated fair values as of the acquisition date, is summarized in the following table (in thousands):
	Amortizable intangible assets:
	Developed technology	$	2,927
	Customer relationships	643
	Trade name	41
	Goodwill	1,409
	Total purchase consideration	$	5,020
	Developed technology consists of the technology underlying MortgageCEO’s existing products and has an estimated useful life of 5 years. The value of the developed technology was determined by discounting the estimated net future cash flows of these products.
	Customer relationships relate to the Company’s ability to sell existing and future versions of the Company’s products and services to existing MortgageCEO customers and have an estimated useful life of five years. The fair value of the customer relationships was determined by discounting the estimated future net cash flows from future sales to existing customers.
	Trade name represents the right to use the MortgageCEO name and has an estimated useful life of two years. The fair value of the trade name was determined by estimating the benefit from owning the asset rather than paying a royalty to a third party for the use of the asset.
	Goodwill, which is deductible for tax purposes, represents the excess of the purchase price over the fair value of the identifiable assets acquired. Among the factors that contributed to a purchase price in excess of the fair value of the identifiable assets was the acquisition of an assembled workforce and synergies between the Company’s products and MortgageCEO’s products.
	MortgageCEO’s results of operations since the closing date of January 15, 2014 have been included in the Company’s consolidated statements of comprehensive income for the year ended December 31, 2014. If the acquisition had occurred as of January 1, 2014, the revenue and earnings of the combined entity for the current reporting period would have been approximately the same. MortgageCEO’s revenues and earnings for the year ended December 31, 2014 were not significant.
	As described in Note 6, during the fourth quarter of 2014, the Company recorded a non-cash impairment charge of $0.3 million to customer relationships and a non-cash impairment charge of $1.7 million to developed technology acquired in the MortgageCEO acquisition.
	AllRegs
	On October 1, 2014, the Company acquired substantially all the assets of Mortgage Resource Center, Inc. (dba AllRegs) (“AllRegs), a provider of research and reference, education, documentation and data and analytics products relating to the mortgage industry. The Company acquired the AllRegs business in order to strengthen the Company’s products through product integration and to introduce new products related to training, compliance management systems and product eligibility. The transaction was accounted for as a business combination and, accordingly, the total purchase price was allocated to the assets acquired based on their respective fair values. The Company expensed all transactions costs, which were insignificant, in the period in which they were incurred.
	The total purchase consideration was $28.1 million in cash, of which $3.0 million was placed in escrow to cover closing capital settlement adjustments and any indemnity claims. Any amount remaining in escrow 18 months after the date of acquisition will be paid to the seller.
	The allocation of the consideration of $28.1 million to the identifiable tangible and intangible assets acquired and liabilities assumed under the purchase method of accounting, based on their estimated fair values as of the acquisition date, is summarized in the following table (in thousands):
	Current assets	$	127
	Property and equipment	494
	Deposits and other assets	8
	Intangible assets:
	Developed technology	3,256
	In-process research and development	618
	Customer relationships	9,585
	Trade name	4,039
	Current liabilities	(383		)
	Deferred revenue	(2,484		)
	Goodwill	12,878
	Total purchase consideration	$	28,138
	Developed technology consists of the technology underlying AllRegs’s existing products and has an estimated useful life of two years. The value of the developed technology was determined by estimating the cost to reproduce the technology.
	In-process research and development represents the fair value of incomplete AllRegs research and development projects that had not reached technological feasibility as of the date of acquisition. The value of the in-process research and development was determined by estimating the cost to reproduce the research and development projects. The research and development projects were assigned an indefinite useful life until the research and development efforts were completed in December 2014, at which point the Company determined that the completed project, now recorded as developed technology, had an estimated useful life of three years.
	Customer relationships relate to the Company’s ability to sell existing and future versions of the Company’s products and services to existing AllRegs customers and have an estimated useful life of six years. The fair value of the customer relationships was determined by discounting the estimated future net cash flows from future sales to these customers.
	Trade name represents the right to use the AllRegs name and has an indefinite useful life. The fair value of the trade name was determined by estimating the benefit from owning the asset rather than paying a royalty to a third party for the use of the asset.
	Goodwill, which is deductible for tax purposes, represents the excess of the purchase price over the fair value of the identifiable assets acquired. Among the factors that contributed to a purchase price in excess of the fair value of the identifiable assets was the acquisition of an assembled workforce and synergies between the Company’s products and AllRegs’s products.
	AllReg’s results of operations since the closing date of October 1, 2014, have been included in the Company’s consolidated statements of comprehensive income for the year ended December 31, 2014 including related revenues of approximately $2.0 million.
	The following unaudited pro forma combined results of operations give effect to the acquisition of AllRegs as if it had occurred on January 1, 2013. The unaudited pro forma combined results of operations are provided for informational purposes only and do not purport to represent the Company’s actual consolidated results of operations or consolidated financial position had the acquisition occurred on the dates assumed, nor are these financial statements necessarily indicative of the Company’s future consolidated results of operations or consolidated financial position. The Company expects to incur costs and realize benefits associated with integrating the operations of the Company and AllRegs. The unaudited pro forma combined results of operations do not reflect the costs of any integration activities or any benefits that may result from operating efficiencies or revenue synergies. The pro forma combined results of operations for the years ended December 31, 2014 and 2013 include non-recurring adjustments relating to the reduction of AllRegs deferred revenue to its estimated fair value as of the acquisition date and the corresponding impact on subsequently recognized revenue, direct acquisition costs and changes to AllRegs employee compensation subsequent to the date of acquisition.

Amortization of internal-use software for the years ended December 31, 2014 and 2013 was $0.7 million and $0.1 million, respectively. There was no amortization of internal-use software for the year ended December 31, 2012.
	The cost of property and equipment at December 31, 2014 included a total of $2.0 million of computer equipment and $0.5 million of software under capital leases. Accumulated amortization relating to computer equipment and software under capital leases totaled $0.9 million at December 31, 2014. The cost of property and equipment at December 31, 2013 included a total of $1.0 million of computer equipment and $0.5 million of software under capital leases.

	During the fourth quarter of 2014, the Company identified certain indicators of impairment for both the customer relationships and developed technology acquired in the MortgageCEO acquisition. Specifically, the Company determined it would need to make additional investments in the Encompass CRM product, including in the areas of security, stability and functionality in order to attract new customers (which were not expected and therefore not contemplated in the valuation of customer relationships and developed technology in the purchase price allocation at the acquisition date). The need to make these investments has resulted in a significant delay in the Company’s ability to release an integrated Encompass CRM product to its customers. As a result, the Company determined it was necessary to assess the recoverability of the customer relationships and developed technology associated with generating Encompass CRM cash flows. The Company used an income approach to determine if the sum of the undiscounted cash flows expected to result from the use and eventual disposition of each asset exceeded the carrying amount of that asset. As a result of this assessment, it was determined that the sum of undiscounted cash flows was less than the carrying amount for each of the two assets. In order to determine the amount of impairment to each asset, the Company performed an analysis to determine the fair value of each asset, which was determined using the present value of expected future cash flows which were based on estimates, assumptions and judgments. These include the forecast of future cash flows related to each asset, the discount rate used in discounting those cash flows, and the expected remaining useful life of each asset. This analysis resulted in a non-cash impairment charge of $0.3 million to customer relationships and a non-cash impairment charge of $1.7 million to developed technology, which were included in sales and marketing expenses and research and development expenses, respectively, in the consolidated statements of comprehensive income for the year ended December 31, 2014. The Company reassessed the useful life of the customer relationships and developed technology and determined that they remained appropriate.
	Amortization expense associated with intangible assets was $2.8 million, $1.4 million and $1.6 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Minimum future amortization expense for intangible assets at December 31, 2014 was as follows:

	The provision for income taxes differed from the amount of income taxes determined by applying the U.S. statutory federal income tax rate as follows:
		Year ended December 31,
		2014			2013			2012
	Tax at federal statutory rate	35	%		35	%		34	%

	Income tax provision	31	%		31	%		8	%
	Excess tax benefits associated with stock option exercises and other equity awards were credited to stockholders’ equity. The income tax benefits resulting from stock awards that were credited to stockholders’ equity were $5.9 million, $7.0 million and $2.0 million for the years ended December 31, 2014, 2013 and 2012.
	The components of net deferred tax assets (liabilities) were as follows:
		December 31,
		2014				2013
		(in thousands)
	Deferred tax assets
	Research and development credits	$	2,897			$	2,226
	Stock-based compensation	6,802				5,084
	Reserves and accruals	3,613				2,056
	Net operating loss carryforwards	366				625
	Total deferred tax assets	13,678				9,991
	Valuation allowance	(2,897		)		(2,056		)
	Total deferred tax assets, net of valuation allowance	10,781				7,935
	Deferred tax liabilities
	Depreciation and amortization	(6,026		)		(2,944		)
	Book/tax basis in acquired assets	(271		)		(112		)
	Total deferred tax liabilities	(6,297		)		(3,056		)
	Net deferred tax assets	$	4,484			$	4,879
	At December 31, 2014, the Company had recorded $5.1 million of net current deferred tax assets in prepaid expenses and other current assets, $0.6 million of net long-term deferred tax assets in deposits and other assets and $1.3 million of net long-term deferred tax liabilities in other long-term liabilities on the consolidated balance sheet. At December 31, 2013, the Company had recorded $23,000 of net current deferred tax assets in prepaid expenses and other current assets and $4.9 million of net long-term deferred tax assets in deposits and other assets.
	The Company continues to maintain a valuation allowance against the deferred tax assets related to certain state research and development tax credits, the realization of which is uncertain as the Company expects to generate additional such credits at a faster rate than it is able to utilize them. The valuation allowance decreased by $6.5 million in 2012, increased by $0.3 million in 2013 and increased by $0.8 million in 2014.
	The Company utilized all of its federal net operating loss (“NOL”) during the year ended December 31, 2013. As of December 31, 2014, the Company had state NOL carryforwards of $7.4 million, available to reduce future taxable income. These state NOL carryforwards will begin to expire commencing in 2015. As of December 31, 2014, the Company also had federal and state research and development tax credit carryforwards of $4.7 million and $5.6 million, respectively. If it were to be utilized, the related federal tax benefit of $4.7 million would be credited to additional paid-in capital. The federal tax credit carryforwards begin to expire commencing in 2033. The state tax credit carryforwards may be carried forward indefinitely.
	Internal Revenue Code Section 382 places a limitation (the “Section 382 Limitation”) on the amount of taxable income that can be offset by NOL carryforwards after a change in control (generally greater than 50% change in ownership) of a loss corporation. California has similar rules. The Company’s capitalization as described herein may have created such a change. Generally, after a control change, a loss corporation cannot deduct NOL carryforwards in excess of the Section 382 Limitation. Due to these “change in ownership” provisions, utilization of the NOL carryforwards may be subject to an annual limitation regarding their utilization against taxable income in future periods. The Company has prepared a Section 382 Limitation analysis and does not believe that any of its NOL carryforwards are subject to expiration prior to utilization. Limitations have been imposed on the Company’s acquired subsidiaries.
	At December 31, 2014, the Company had $2.4 million of cumulative unrecognized tax benefits. If the benefits were to be recognized, $1.2 million would affect the effective tax rate and $1.2 million would reverse the valuation allowance against the deferred tax assets. The Company does not expect a significant change to its unrecognized tax benefits over the next twelve months. The unrecognized tax benefits may increase or change during the year for items that arise in the ordinary course of business.
	A reconciliation of the beginning and ending balance of unrecognized tax benefits is as follows:
		Year ended December 31,
		2014				2013				2012
		(in thousands)
	Beginning balance	$	1,806			$	1,262			$	1,855
	Additions based on tax positions related to the current year	594				402				130
	(Deductions) additions based on tax positions related to prior years including acquisitions	8				142				(723		)
	Ending balance	$	2,408			$	1,806			$	1,262
	The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions. The Company’s tax years for 2001 and forward are subject to examination by the U.S. tax authorities and for 2000 and forward are subject to examination by the California tax authorities due to the carryforward of unutilized net operating losses and research and development credits.
	The Company believes that it has provided adequate reserves for its income tax uncertainties in all open tax years, and that it does not have any tax positions that it is reasonably possible would materially increase or decrease the gross unrecognized tax benefits within the next twelve months.
	The Company has a policy to classify accrued interest and penalties associated with uncertain tax positions together with the related liability, and the expenses incurred related to such accruals are included in the provision for income taxes. The Company did not incur any interest expense or penalties associated with unrecognized tax benefits during the years ended December 31, 2014, 2013 and 2012.
	Enactment of the American Tax Relief Act
	On December 19, 2014, the President signed into law The Tax Increase Prevention Act of 2014.  Under prior law, a taxpayer was entitled to a research tax credit for qualifying amounts paid or incurred on or before December 31, 2013.

Certain leases contain escalation clauses calling for increased rents. The Company recognizes rent expense on a straight-line basis over the lease period and has recorded deferred rent for the difference between rent payments and rent expense recognized. Rent expense was $2.1 million, $1.6 million, and $1.2 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	The Company leases certain fixed assets under noncancelable capital leases with various expiration dates. In January 2015, the Company entered into a lease agreement to finance the purchase of computer equipment for the Company’s data centers with payments of $0.3 million per month over the 24 month term of the agreement.
	Future minimum lease payments under non-cancelable operating and capital leases at December 31, 2014 consisted of the following:

Included in these amounts are the payments associated with the lease agreement to finance the purchase of computer equipment that the Company entered into in January 2015.
	Acquisition Holdback
	As of December 31, 2014, the Company maintained potential future acquisition holdback payments of $0.5 million, which may be payable during 2015.
	Legal Proceedings
	On March 25, 2011, Industry Access Incorporated (“Industry Access”) filed a patent infringement lawsuit against the Company and another defendant in the U.S. District Court for the Central District of California, alleging, among other things, that certain aspects of our Encompass loan management software system and related operations infringe U.S. Patent No. 7,769,681. On March 19, 2013, Industry Access filed a second patent infringement lawsuit against the Company in the U.S. District Court for the Central District of California, alleging, among other things, that our Encompass loan management software system, including the Encompass software, the Ellie Mae Network, Encompass Originator, Encompass Compliance Service, Encompass CenterWise, Encompass Electronic Document Management, Encompass Docs Solution and Encompass Product and Pricing Service, infringes U.S. Patent Nos. 8,117,120 and 8,145,563, which are continuations of U.S. Patent No. 7,769,681. In both matters, Industry Access sought unspecified damages, including enhanced damages for willful infringement and reasonable attorneys’ fees. On September 12, 2013, the Company filed a motion to relate and consolidate the two Industry Access lawsuits, which the court granted on October 31, 2013. The Court held a claim construction hearing on June 2, 2014, and issued a claim construction order on July 9, 2014. On September 29, 2014, the Company settled all related matters with Industry Access, which settlement is reflected in its financial results for the year ended December 31, 2014.
	The Company is also subject to various other legal proceedings and claims whose outcome the Company does not expect to have a material adverse effect on its financial position. However, litigation is unpredictable and excessive verdicts, both in the form of monetary damages and injunctions, could occur. In the future, litigation could result in substantial costs and diversion of resources and the Company could incur judgments or enter into settlements of claims that could have a material adverse effect on its business.

	The Company recognizes stock-based compensation related to awards granted under the 2009 Plan, the 2011 Plan and ESPP.
	2009 Stock Option and Incentive Plan and 2011 Equity Incentive Award Plan
	Stock Options
	In March 2009, the Company adopted the 2009 Plan. On March 7, 2011, the Company adopted the 2011 Plan. The Company’s stockholders approved the 2011 Plan on March 24, 2011.
	Under the 2011 Plan, 2,666,666 shares of the Company’s common stock were initially reserved. Additionally, any shares of common stock that were available for issuance under prior plans, including the 2009 Plan, were transferred to the 2011 Plan. As of December 31, 2014, 984,924 shares of the Company’s common stock previously available for issuance under the 2009 Plan were available for issuance under the 2011 Plan. The number of common shares reserved for issuance under the 2011 Plan increase automatically in January of each year by the least of (a) 1,666,666 shares, (b) five percent (5%) of the shares of common stock outstanding on the last day of the immediately preceding fiscal year and (c) such smaller number of shares of common stock as determined by the Company’s board of directors; provided, however that no more than 23,333,333 shares of common stock may be issued upon the exercise of incentive stock options.
	In April 2009, the Company replaced employee options for 1,993,923 shares with exercise prices of $5.40 and $5.94 with options having an exercise price of $1.38 and which included new vesting periods in accordance with the terms of the repricing plan (“April 2009 repricing”). The replacement options resulted in incremental stock-based compensation expense of $0.7 million, which was recognized ratably as the awards vested between March 2009 and October 2012.
	In August 2007, the Company granted an option to purchase 450,000 shares of the Company’s common stock at an exercise price of $5.94 per share to an executive officer of the Company. The option was canceled and repriced at $1.38 as part of the April 2009 repricing. Such option contains a performance requirement with vesting triggered by a liquidity event of the Company and the number of vested shares is determined based upon a return multiple as defined in the agreement. Upon the IPO in April 2011, as a liquidity event defined in the agreement occurred, the Company began recognizing compensation expense. The options were fully vested as of December 31, 2012. The related compensation expense recognized for the year ended December 31, 2012 was $0.2 million.
	The following table summarizes the Company’s stock option activity under the 2009 Plan and 2011 Plan:
		Number of		Weighted				Weighted		Aggregate

	Intrinsic value of an option is the difference between the fair value of the Company’s common stock at the time of exercise and the exercise price to be paid. The aggregate intrinsic value for options outstanding at December 31, 2014 in the table above represents the total intrinsic value, based on the Company’s closing stock price of $40.32 as of December 31, 2014. Options outstanding that are expected to vest are net of estimated future option forfeitures. For the majority of stock options outstanding, the options vest over a four-year period and have a maximum contractual term of ten years.
	Following is additional information pertaining to the Company’s stock option activity:

	As of December 31, 2014, total unrecognized compensation cost related to unvested stock options, adjusted for estimated forfeitures, was $14.6 million and is expected to be recognized over a weighted average period of 2.53 years.
	Restricted Stock Units and Performance Awards
	The fair value of the Company’s RSUs and Performance Awards is measured based upon the closing price of its underlying common stock as of the grant date and is recognized over the vesting term. Upon vesting, RSUs convert into an equivalent number of shares of common stock.
	In August 2012, the Company granted 147,000 Performance Awards (“2012 Performance Awards”) to designated participants under the 2011 Plan. The 2012 Performance Awards represented the right to receive shares of the Company’s common stock upon achievement of certain performance goals during the performance period of July 1, 2012 through June 30, 2013. In August 2013, after the Company filed with the SEC its Quarterly Report on Form 10-Q for the quarter ended June 30, 2013, the Compensation Committee determined the level of achievement of the performance goals (the “Determination Date”), at which time the designated participants earned an aggregate of 588,000 shares of common stock. The earned shares were issued in August 2013, with 25% of the shares vested upon issuance and the remaining shares to vest 25% on each of the first three anniversaries of the Determination Date, subject to the continuous employment of the participant through such dates.
	In February 2013, the Company granted 113,000 Performance Awards (“2013 Performance Awards”) to designated participants under the 2011 Plan. The 2013 Performance Awards represent the right to receive shares of the Company’s common stock upon achievement of certain performance goals during the performance period of January 1, 2013 through December 31, 2013. In March 2014, after the Company filed with the SEC its Annual Report on Form 10-K for the year ended December 31, 2013, the Compensation Committee determined the level of achievement of the performance goals (the “2013 Award Determination Date”), at which time it was determined that the designated participants had earned an aggregate of 124,300 shares of common stock. The earned shares were issued in April 2014, with 25% of the shares vested upon issuance and the remaining shares to vest 25% on each of the first three anniversaries of the 2013 Award Determination Date, subject to the continuous employment of the participant through such dates.
	In February 2014, the Company granted 62,500 Performance Awards (“2014 Performance Awards”) to designated participants under the 2011 Plan. The 2014 Performance Awards represent the right to receive shares of the Company’s common stock upon achievement of certain performance goals during the performance period of January 1, 2014 through December 31, 2014. After the Company files with the SEC its Annual Report on Form 10-K for the year ending December 31, 2014, the Compensation Committee will determine the level of achievement of the performance goals (the “2014 Award Determination Date”), at which time the designated participants may earn between zero and 2.5 shares of common stock for each 2014 Performance Award. Shares of common stock earned, if any, will be issued after the 2014 Award Determination Date with 25% of the shares to vest upon issuance and the remaining shares to vest 25% on each of the first three anniversaries of the 2014 Award Determination Date, subject to the continuous employment of the participant through such dates. As of December 31, 2014, the Company expects that each award will convert to 1.9 shares of common stock on the 2014 Award Determination Date.
	In December 2014, the Company granted Sigmund Anderman, then Chief Executive Officer and current Chairman of the Board of Directors of the Company, an option to purchase 76,648 shares of Company common stock and 37,203 performance-vesting RSUs. Each of the options will have a four-year, employment-based vesting schedule with the first 25% total number of shares vested on the first anniversary of the grant date and 1/48th of the original number of shares on each monthly anniversary. Each of the performance-vesting RSUs will vest based upon the achievement of the corporate goals for fiscal year 2015 and continued employment. On the date the board of directors or the compensation committee certifies the achievement of the Company’s corporate goals for fiscal year 2015 (the “2015 RSU Determination Date”), Mr. Anderman may earn up to 2.0 shares of common stock for each of the performance-vesting RSUs. 25% of the total number of performance-vesting RSUs will vest and be issued on the 2015 RSU Determination Date, and the remaining shares will vest and be issued 25% on each of December 31, 2016, 2017 and 2018, subject to the continuous employment of Mr. Anderman through such dates.

RSUs and Performance Awards that are expected to vest are net of estimated future forfeitures. RSUs released during the years ended December 31, 2014 and 2013 had an aggregate intrinsic value of $2.6 million and $0.5 million, respectively, and an aggregate grant-date fair value of $1.9 million and $0.3 million, respectively. Performance Awards released during the years ended December 31, 2014 and 2013 had an aggregate intrinsic value of $5.9 million and $4.5 million, respectively, and an aggregate grant-date fair value of $4.4 million and $3.8 million, respectively. The number of RSUs released includes shares that the Company withheld on behalf of employees to satisfy the minimum statutory tax withholding requirements.
As of December 31, 2014, total unrecognized compensation expense related to unvested RSUs and Performance Awards was $17.7 million and is expected to be recognized over a weighted average period of 2.6 years.
Subsequent to year-end, in January 2015, the Company granted Mr. Anderman an option to purchase 71,648 shares of Company common stock and 34,714 performance-vesting RSUs. Each of the options will have a four-year, employment-based vesting schedule with the first 25% total number of shares vested on the first anniversary and 1/48th of the original number of shares on each monthly anniversary. Each of the performance-vesting RSUs will vest based upon the achievement of the corporate goals for fiscal year 2015 and continued employment. On the 2015 RSU Determination Date, Mr. Anderman may earn up to 2.0 shares of common stock for each of the performance-vesting RSUs. 25% of the total number of performance-vesting RSUs will vest and be issued on a Determination Date, and the remaining shares will vest and be issued 25% on each of December 31, 2016, 2017 and 2018, subject to the continuous employment of Mr. Anderman through such dates.
Subsequent to year-end, in February 2015, the Company granted 24,766 Performance Awards (“2015 Performance Awards”) to designated participants under the 2011 Plan. The 2015 Performance Awards represent the right to receive shares of the Company’s common stock upon achievement of certain performance goals during the performance period of January 1, 2015 through December 31, 2015. After the Company files with the SEC its Annual Report on Form 10-K for the year ending December 31, 2015, the Compensation Committee will determine the level of achievement of the performance goals (the “2015 Award Determination Date”), at which time the designated participants may earn between zero and 2.0 shares of common stock for each 2015 Performance Award. Shares of common stock earned, if any, will be issued after the 2015 Award Determination Date with 25% of the shares to vest upon issuance and the remaining shares to vest 25% on each of the first three anniversaries of the 2015 Award Determination Date, subject to the continuous employment of the participant through such dates.
Stock Awards Issued to Non-employees
During the year ended December 31, 2014, the Company granted 5,931 RSUs to individual consultants at a weighted average grant date fair value of $25.30 per share. During the year ended December 31, 2013, the Company granted options to purchase approximately 6,000 shares of common stock to individual consultants at a weighted average exercise price of $28.00 per share.
The RSUs and options were granted in exchange for consulting services. The RSUs and options each vest over a period of two years. These awards were granted under the 2011 Plan and are included in the RSU and option tables above. The RSUs and options issued to consultants are remeasured to fair value at the end of each accounting period. The Company recorded expense related to the issuance of RSUs and options to consultants of $0.2 million and $0.2 million in each of the years ended December 31, 2014 and 2013.
Employee Stock Purchase Plan
Under the ESPP, qualified employees are permitted to purchase the Company’s common stock at 85% of the fair market value of the common stock as of the commencement date of the offering period or as of the specified purchase date, whichever is lower. The ESPP is deemed compensatory and stock-based compensation is recognized in accordance with ASC 718, Stock Compensation.
The ESPP is designed to allow eligible employees and the eligible employees of the Company’s participating subsidiaries to purchase shares of common stock, at semi-annual intervals, with their accumulated payroll deductions.
The maximum aggregate number of shares which may be issued over the term of the ESPP is the sum of (a) 666,666 shares of common stock and (b) an annual increase on the first day of each year beginning in 2012 and ending in 2021, equal to the least of (i) 1,666,666 shares of common stock, (ii) one percent (1%) of the shares of common stock outstanding (on an as converted basis) on the last day of the immediately preceding fiscal year and (iii) such smaller number of shares of common stock as determined by the board of directors, which may be either authorized but unissued common stock or reacquired common stock, including shares of common stock purchased on the open market. In addition, no participant shall be permitted to participate in the ESPP if: (i) immediately after his or her election to participate, the participant would control 5% or more of the total combined voting power or value of all classes of the stock of the Company or any of its affiliates, or (ii) under the terms of the ESPP, the rights of the participant to purchase the Company’s common stock under the ESPP and all of its other qualified employee stock purchase plans or those of the Company’s affiliates would accrue at a rate exceeding $25,000 of fair market value of the common stock for each calendar year for which such right is outstanding at any time.
The weighted-average grant-date fair value of awards issued pursuant to the ESPP during the years ended December 31, 2014 and 2013 were $7.71 and $5.24 per share, respectively.
For the years ended December 31, 2014 and 2013, employees purchased 102,111 and 109,270 shares under the ESPP for a total of $2.6 million and $1.9 million, respectively. As of December 31, 2014, unrecognized compensation cost related to the current ESPP period which ends on February 27, 2015 was approximately $0.2 million and is expected to be recognized over the next 2 months.
Stock-Based Compensation Expense
Total stock-based compensation expense recognized by the Company consisted of:
	Year ended December 31,
	2014			2013				2012
	(in thousands)
Stock-based compensation by category of expense:
Cost of revenues	$	1,579		$	745			$	271
Sales and marketing	1,562			1,041				467
Research and development	3,672			3,469				1,552
General and administrative	7,735			9,004				4,559
	$	14,548		$	14,259			$	6,849
The Company capitalized $0.5 million and $0.1 million of stock compensation costs as software and website application development costs for the years ended December 31, 2014 and 2013, respectively. The Company did not capitalize any stock-based compensation for the year ended December 31, 2012 as such amounts were insignificant.
Valuation Information
The fair value of stock options and stock purchase rights granted under the 2009 Plan, the 2011 Plan and the ESPP were estimated at the date of grant using the Black-Scholes option valuation model with the following weighted average assumptions:
	Year ended December 31,
	2014		2013			2012
Stock option plans:
Risk-free interest rate	1.55-2.02	%	0.95-1.87	%		0.74-1.10		%
Expected life of options (in years)	5.27-6.08		5.27-6.08			5.27-6.08
Expected dividend yield	—	%	—	%		—		%
Volatility	49-53	%	50-52	%		52-59		%
Employee Stock Purchase Plan:
Risk-free interest rate	0.05-0.08	%	0.05-0.13	%		0.13-0.14		%
Expected life of options (in years)	0.5		0.5			0.5
Expected dividend yield	—	%	—	%		—		%
Volatility	38-39	%	36-37	%		37-47		%
Due to the Company’s limited trading history as a publicly held company, the simplified method was used to estimate the expected term of options granted by taking the average of the vesting term and the contractual term of the option. To estimate volatility, management identified a group of publicly traded peer companies that operate in a similar industry. An estimate was determined based on a weighted average of the historical volatilities of these peer companies and the Company’s common stock during the period of time since the Company’s initial public offering. The risk-free interest rate used was the Federal Reserve Bank’s constant maturities interest rate commensurate with the expected life of the options. The expected dividend yield was zero, as the Company does not anticipate paying a dividend within the relevant time frame.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation
	The consolidated financial statements include the accounts of Ellie Mae and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
	Certain adjustments primarily related to the Company’s tax provision for the year ended December 31, 2013 have been made as further described in Note 2, under “Correction of Immaterial Errors.” In addition, certain amounts in prior periods have been reclassified to conform to current period presentation, with no effect on previously reported net income or stockholders’ equity.
Use of Estimates	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 and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management evaluates estimates on a regular basis including those relating to revenue recognition, the allowance for doubtful accounts, goodwill, intangible assets, the valuation of deferred income taxes, stock-based compensation and unrecognized tax benefits, among others. Actual results could differ from those estimates and such differences may have a material impact on the Company’s consolidated financial statements and footnotes.
Cash and Cash Equivalents	Cash and Cash Equivalents
	All highly liquid investments with original maturities of 90 days or less are considered to be cash equivalents. Cash equivalents are recorded at cost, which approximates fair value.
Fair Value of Financial Instruments	Fair Value of Financial Instruments
	The fair values of the Company’s cash equivalents, accounts receivable and accounts payable approximate their carrying values due to the short maturities of the instruments. The fair value of the Company’s capital lease obligations approximates the carrying value due to the terms continuing to approximate prevailing market terms.
	All of the Company’s investments that have maturities of greater than 90 days are classified as available-for-sale and are carried at fair value. The Company invests excess cash primarily in investment-grade interest-bearing securities, such as money market accounts, certificates of deposit, commercial paper, corporate bonds, municipal and government agency obligations and guaranteed obligations of the U.S. government. Fair value is determined based on quoted market rates when observable or utilizing data points that are observable, such as quoted prices, interest rates and yield curves. The cost of available-for-sale marketable securities sold is based on the specific identification method. Unrealized gains and losses are reported in stockholders’ equity as accumulated other comprehensive (income) loss. Realized gains and losses are included in other income (expense), net. Interest and dividends are included in other income (expense), net when they are earned.
Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts
	Trade accounts receivable consist of amounts billed to customers in connection with sales of services. The Company analyzes individual trade accounts receivable by considering historical bad debts, customer creditworthiness, current economic trends, changes in customer payment terms and collection trends when evaluating the adequacy of the allowance for doubtful accounts. Allowances for doubtful accounts are recognized in the period in which the associated receivable balance is not considered recoverable. Any change in the assumptions used in analyzing accounts receivable may result in changes to the allowance for doubtful accounts and is recognized in the period in which the change occurs. The Company writes off a receivable when all rights, remedies and recourses against the account and its principals are exhausted and records a benefit when previously reserved accounts are collected.
Concentration of Credit Risk	Concentration of Credit Risk
	The financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments and accounts receivable. The Company’s cash and cash equivalents are deposited with major financial institutions in the United States. At times, such deposits may be in excess of federally insured limits. Management believes that the Company’s investments in cash equivalents and available-for-sale investments are financially sound. The Company’s accounts receivable are derived from revenue earned from customers located in the United States. The Company had no customers that represented 10% or more of revenues for the years ended December 31, 2014, 2013 and 2012. No customer represented more than 10% of accounts receivable as of December 31, 2014 and 2013.
Software and Web Site Development Costs	Software and Website Development Costs
	The Company capitalizes internal and external costs incurred to develop internal-use software and website applications. Capitalized internal costs include salaries, benefits and stock-based compensation charges for employees that are directly involved in developing the software or website application, and depreciation of assets used in the development process. Capitalized external costs include third-party consultants involved in the development process, as well as other direct costs incurred as part of the development process.
	Capitalization of costs begins when the preliminary project stage has been completed, management authorizes and commits to funding a project and it is probable that the project will be completed and the software or website application will be used to perform the function intended. Internal and external costs incurred as part of the preliminary project stage are expensed as incurred.
	Capitalization ceases at the point at which the project is substantially complete and ready for its intended use. Internal and external training costs and maintenance costs during the post-implementation operation stage are expensed as incurred.
	Internal-developed core software is amortized on a straight-line basis over its estimated useful life, generally three to five years. Amortization of product related internal-use software and website applications is typically recorded to cost of revenues, and amortization of other internal-use software and website applications is typically recorded to the operating expense line to which it most closely relates. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. The capitalized costs are included in property and equipment, net in the accompanying consolidated balance sheets. For the years ended December 31, 2014, 2013 and 2012, the Company capitalized software and website application development costs of $15.9 million, $5.1 million, and $0.5 million, respectively.
	During the year ended December 31, 2014, the Company recorded a $0.7 million impairment loss on the write-off of internal-use software. There were no such write-offs during the years ended December 31, 2013 and 2012.
Property and Equipment	Property and Equipment
	Property and equipment are stated at cost less accumulated depreciation and are depreciated on a straight-line basis over their estimated useful lives, which is generally three to seven years. Leasehold improvements are amortized on a straight-line basis over their estimated useful lives or over the term of the lease, whichever is shorter.
Business Combinations	Business Combinations
	The Company recognizes and measures the identifiable assets acquired in a business combination, the liabilities assumed and any non-controlling interest in the acquiree, measured at their fair values as of the acquisition date. The Company recognizes contingent consideration arrangements at their acquisition-date fair values with subsequent changes in fair value reflected in earnings, recognizes pre-acquisition loss and gain contingencies at their acquisition-date fair values (with certain exceptions), capitalizes in-process research and development assets and expenses acquisition-related transaction costs as incurred. Due to the inherent uncertainty in the Company’s best estimates and assumptions, they are subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of assets acquired and liabilities assumed, with the corresponding offset to goodwill. Any subsequent adjustments, including changes in accounting for deferred tax asset valuation allowances and acquired income tax uncertainties after the measurement period, are recognized in earnings rather than as an adjustment to the cost of the acquisition.
Goodwill and Other Intangible Assets	isition.
	Goodwill
	The Company records goodwill in a business combination when the consideration paid exceeds the fair value of the net assets acquired. Goodwill is not amortized, but is tested for impairment at least annually in the fourth quarter of the Company’s fiscal year, or whenever changes in circumstances indicate that the fair value of a reporting unit is less than its carrying amount, including goodwill. The annual test is performed at the reporting unit level using a fair-value based approach. The Company’s operations are organized as one reporting unit. In testing for a potential impairment of goodwill, the Company first compares the carrying value of assets and liabilities to the estimated fair value. If estimated fair value is less than carrying value, then potential impairment exists. The amount of any impairment is then calculated by determining the implied fair value of goodwill using a hypothetical purchase price allocation. Impairment is equivalent to any excess of goodwill carrying value over its implied fair value. There were no impairment charges related to goodwill during the years ended December 31, 2014, 2013, and 2012.
	The process of evaluating the potential impairment of goodwill requires significant judgment at many points during the analysis, including calculating fair value of the reporting unit based on estimated future cash flows and discount rates to be applied.
	Intangible Assets
	Intangible assets are stated at cost less accumulated amortization. Intangible assets include developed technology, trade names and customer lists and contracts. Intangible assets with finite lives are amortized on a straight-line basis over the estimated periods of benefit, as follows:
	Developed technology	2-5 years
	Trade names with finite lives	2-3 years
	Customer lists and contracts	4-9 years
	Intangible assets with indefinite useful lives, including the AllRegs trade name, are stated at cost. The Company evaluates the remaining useful life of indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support an indefinite useful life.
	The Company evaluates its finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset or asset group to future undiscounted net cash flows expected to be generated by the asset or asset group. If such assets or asset groups are considered to be impaired, the impairment loss to be recognized is measured by the amount by which the carrying amounts of the assets or asset groups exceed the fair value of the assets or asset groups. Assets to be disposed of are reported at the lower of the carrying amount and fair value less costs to sell. Except as described in Note 6, there has been no loss on impairment or disposal of intangible assets.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets
	The Company evaluates its long-lived assets for indications of possible impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Except for the impairment losses recorded on internal-use software and intangible assets described elsewhere in this note, there has been no loss on impairment or disposal of long-lived assets.
Revenue Recognition	Revenue Recognition
	The Company generates revenues primarily from transaction-based fees and fees for software and related services. On-demand revenues are revenues generated from company-hosted software subscriptions that customers access through the Internet and revenues from customers that pay fees based on a per closed loan, or success, basis subject to monthly base fees, which the Company refers to as Success-Based Pricing. Additionally, on-demand revenues are comprised of software services sold transactionally; Ellie Mae Network transaction fees; education and training, loan product and guideline data and analytics services under the AllRegs brand; and professional services which include consulting, implementation and training services. On-premise revenues are revenues generated from maintenance services, sales of customer-hosted software licenses, and professional services. Sales taxes assessed by governmental authorities are excluded from revenue.
	The Company commences revenue recognition when all of the following conditions are satisfied:
	•There is persuasive evidence of an arrangement;
	•The service has been or is being provided to the customer;
	•The collection of the fees is reasonably assured; and
	•The amount of fees to be paid by the customer is fixed or determinable.
	On-Demand Revenues
	Subscription Services and Usage-Based Fee Arrangements. Subscription services and usage-based fee arrangements generally include a combination of the Company’s products delivered as software-as-a-service (“SaaS”) and support services. These arrangements are generally non-cancelable and do not contain refund-type provisions. These revenues typically include the following:
	SaaS Encompass Revenues. The Company offers web-based, on-demand access to Encompass software for a monthly recurring fee. The Company provides the right to access its loan origination software and handles the responsibility of managing the servers, providing security, backing up the data and applying updates. Customers under SaaS arrangements may not take possession of the software at any time during the term of the agreement. Subscription revenues are recognized ratably over the contract terms as subscription services are provided, beginning on the commencement date of each contract, which is the date the Company’s service is made available to customers. Contracts generally range from one year to five years.
	Alternatively, customers can elect to pay on a success basis. Success basis contracts generally have a term of one to five years and are subject to monthly base fees, which enable customers to close loans up to a contractually agreed-to minimum number of transactions, and additional closed loan fees, which are assessed for loans closed in excess of the minimum. Revenue is earned from both base fees and additional closed loan fees as the result of the customer’s usage of Encompass. Monthly base fees are recognized over the respective monthly service period as the subscription services are provided. Additional closed loans fees are recognized when the loans are reported as closed. This offering also includes Encompass CenterWise, Encompass Compliance Service and Encompass Docs Solution as integrated components, which are combined elements of the arrangement that are delivered in conjunction with the SaaS Encompass offering and therefore are not accounted for separately.
	Encompass CenterWise Revenues. Encompass CenterWise is a bundled offering of electronic document management (“EDM”) and websites used for customer relationship management. Generally, revenue is recognized for Encompass CenterWise after the service is rendered, except when Encompass CenterWise is automatically included as an integrated component of the SaaS Encompass offering, in which case the associated revenue is recognized as described above.
	Services Revenues. The Company provides a variety of mortgage-related and other business services, including automated documentation; fraud detection, valuation, validation and risk analysis; income verification; marketing and customer management; flood zone certifications; and compliance reports. Services revenues are recognized upon completion of the services.
	Transactional Revenues. The Company has entered into agreements with various lenders, service providers and certain government-sponsored entities participating in the mortgage origination process that provide them access to, and ability to interoperate with, mortgage originators on the Ellie Mae Network. Under these agreements, the Company earns transaction fees when transactions are processed through the Ellie Mae Network. Transaction revenues are recognized when there is evidence that the qualifying transactions have occurred on the Ellie Mae Network and collection of the resulting receivable is reasonably assured.
	Subscriptions to Online Research and Data Resources: The Company provides mortgage originators and underwriters with access to online databases of various federal and state laws and regulations and forms as well as mortgage investor product guidelines. Subscription fees are recognized ratably over the subscription term as subscription services are provided, which is typically one year.
	Professional Services Revenues: Professional services revenues are generally recognized when milestones are achieved for fixed price contracts or as the services are rendered for time and material contracts. The majority of our professional services contracts are on fixed price basis. Training revenues are recognized as the services are rendered.
	On-Premise Revenues
	Revenue from the sale of software licenses is recognized in the month in which the required revenue recognition criteria are met, generally in the month in which the software is delivered. Revenue from the sale of maintenance services and professional services is recognized over the period in which the services are provided.
	Multiple Element Arrangements
	The Company has entered into both subscription services and software arrangements with multiple elements. For arrangements with multiple deliverables, the Company evaluates whether the individual deliverables qualify as separate units of accounting. In order to treat deliverables in a multiple-deliverable arrangement as separate units of accounting, the deliverables must have standalone value upon delivery.
	Subscription services agreements with multiple elements generally include multiple subscriptions and professional services. When such agreements involve multiple elements that qualify as separate units of accounting, the Company allocates arrangement consideration to all deliverables at the inception of an arrangement based on the relative selling price method in accordance with the selling price hierarchy, which includes: (i) vendor specific objective evidence (“VSOE”) if it is available; (ii) third-party evidence (“TPE”) if VSOE is not available; and (iii) the best estimate of selling price (“BESP”) if neither VSOE nor TPE is available.
	VSOE. The Company determines VSOE based on its historical pricing and discounting practices for the specific product or service when sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices for these services fall within a reasonably narrow pricing range. The Company has not historically priced its subscription services within a narrow range. As a result, the Company has not been able to establish selling prices for subscription services based on VSOE.
	TPE. When VSOE cannot be established for deliverables in multiple element arrangements, the Company applies judgment with respect to whether it can establish a selling price based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, the Company’s go-to-market strategy differs from that of its peers and its offerings contain a significant level of differentiation such that the comparable pricing of services with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor services’ selling prices are on a standalone basis. As a result, the Company has not been able to establish selling prices based on TPE.
	BESP. When the Company is unable to establish a selling price using VSOE or TPE, the Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the service was sold on a standalone basis. When establishing BESP, the Company reviews company specific factors used to determine list price and makes adjustments as appropriate to reflect current market conditions and pricing behavior. The Company’s process for establishing list price includes assessing the cost to provide a particular product or service, surveying customers to determine market expectations, analyzing customer demographics and taking into account similar products and services historically sold by the Company. The Company continues to review the factors used to establish list price and adjusts BESP as necessary.
	Because the Company has determined that neither VSOE nor TPE is available, it uses BESP to allocate the selling price to multiple elements in subscription services arrangements. The amount of revenue allocated to delivered items is limited by contingent revenue, if any.
	Subscription services have standalone value as such services are often sold separately. Additionally, the Company has concluded that professional services included in multiple element arrangements have standalone value. In establishing standalone value, the Company considered the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, and the timing of when the professional services contract was signed in comparison to the subscription service start date.
	For software arrangements with multiple elements (e.g., maintenance and support contracts bundled with licenses), revenue is allocated to the delivered elements of the arrangement when VSOE is determinable, using the residual value method based on objective evidence of the fair value of the undelivered elements, which is specific to the Company. When VSOE is not determinable, the entire arrangement is recognized ratably over the term of the contract. Revenue is recognized under this model upon receipt of cash payment from the customer if collectability is not reasonably assured and when other revenue recognition criteria have been met. The VSOE of fair value for maintenance and support obligations related to licenses is based upon the prices paid for the separate renewal of these services by customers. Maintenance revenues are recognized ratably over the period of the maintenance contract.
Deferred Revenue	uses BESP to allocate the selling price to multiple elements in subscription services arrangements. The amount of revenue allocated to delivered items is limited by contingent revenue, if any.

Maintenance revenues are recognized ratably over the period of the maintenance contract.
	Deferred Revenue
	Deferred revenue represents billings or payments received in advance of revenue recognition and is recognized as the revenue recognition criteria are met. Balances consist primarily of prepaid subscription services and professional, training and maintenance services not yet provided as of the balance sheet date. Deferred revenue that will be recognized during the succeeding 12 month period is recorded as current deferred revenue, and the remaining portion is recorded as other long-term liabilities. Long-term deferred revenue at December 31, 2014 and 2013 was not material.
Deferred Commission Expense	Deferred Commission Expense
	Deferred commission expenses are the incremental costs that are directly associated with non-cancelable subscription contracts with customers and consist of sales commissions paid to our direct sales force. Commissions are calculated based on a percentage of the revenues for the non-cancelable term of subscription contracts, which are typically one to five years.
	Prior to 2013, commissions were paid and recognized as sales expense when customer payments for contracted services were received on a monthly basis because commissions were earned based on receipt of customer payments. In 2013, the Company amended its commission plans to provide for payment after the customer’s contract is signed. As a result of the change in commission plans, beginning in 2013, commission expense was deferred and amortized to sales expense over the non-cancelable terms of the related subscription contracts. The deferred commission expense amounts are recoverable through the future revenue streams under the non-cancelable customer contracts. The plans also include claw back provisions, which require repayment of a proportionate amount of commissions, should customers cancel their contracts prior to the end of the initial contractual term.
	During the years ended December 31, 2014 and 2013, the Company deferred $2.5 million and $1.9 million of commission expense, respectively. No amounts were deferred during the year ended December 31, 2012.
	At December 31, 2014 and 2013, $3.3 million and $1.6 million of deferred commission remained on our consolidated balance sheets, respectively.
Warranties and Indemnification	Warranties and Indemnification
	The Company provides a warranty for its software products and services to its customers and accounts for its warranties as a contingent liability. The Company’s software is generally warranted to perform substantially as described in the associated product documentation and to satisfy defined levels of uptime reliability. The Company’s services are generally warranted to be performed consistent with industry standards. The Company has not provided for a warranty accrual as of December 31, 2014 or 2013. To date, the Company’s product warranty expense has not been significant.
	The Company generally agrees to indemnify its customers against legal claims that the Company’s software products infringe certain third-party intellectual property rights and accounts for its indemnification obligations as a contingent liability. In addition, the Company may also incur liability under its contracts if it breaches its warranties as well as certain security and/or confidentiality obligations. To date, the Company has not been required to make any payment resulting from either infringement claims asserted against its customers or from claims in connection with a breach of the security and/or confidentiality obligations in the Company’s contracts. The Company has not recorded a liability for related costs as of December 31, 2014 or 2013.
	The Company has obligations under certain circumstances to indemnify each member of the Company’s board of directors against judgments, fines, settlements and expenses related to claims against such directors and otherwise to the fullest extent permitted under Delaware law and the Company’s bylaws and certificate of incorporation.
Cost of Revenues	Cost of Revenues
	The Company’s cost of revenues consists primarily of salaries, benefits and related costs (including stock-based compensation), allocated facilities costs, customer support, data centers, expenses for document preparation, income verification and compliance services, depreciation on computer equipment used in supporting the Ellie Mae Network, the Company’s SaaS Encompass and Encompass CenterWise offerings, amortization of acquired intangible assets and capitalized internal-use software and website applications directly involved in revenue producing activities and professional services associated with implementation of software.
Research and Development Costs	Research and Development Costs
	The Company’s research and development expenses consist primarily of: salaries and benefits, including bonuses and stock-based compensation expense; fees to contractors engaged in the development and support of the Ellie Mae Network, Encompass software and other products; and allocated facilities costs. Research and development costs that are not capitalized as internal-use software are expensed as they are incurred.
Advertising Expenses	Advertising Expenses
	The Company expenses advertising costs as incurred.
Stock-Based Compensation	were $0.4 million, $0.4 million, and $0.3 million, respectively.
	Stock-Based Compensation
	The Company recognizes stock-based compensation related to awards granted under its 2009 Stock Option and Incentive Plan (the “2009 Plan”), 2011 Equity Incentive Award Plan (the “2011 Plan”) and Employee Stock Purchase Plan (“ESPP”).
	The Company recognizes compensation expense related to stock option grants that are ultimately expected to vest based on estimated fair values on the date of grant using the Black-Scholes option-pricing model. Such expense is recognized on a straight-line basis over the requisite service period of the award, which generally equals the vesting period.
	The Company recognizes compensation expense related to restricted awards, restricted stock unit awards (“RSUs”), and performance share awards (“Performance Awards”) based on the fair market value of the underlying shares of common stock as of the date of grant. Expense related to the restricted awards and the RSUs are recognized on a straight-line basis over the requisite service period of the award, which generally equals the vesting period. Expense related to the Performance Awards is recognized under the graded vesting method over the requisite service period of the award, which recognizes a larger portion of the expense during the beginning of the vesting period than in the end of the vesting period. Management estimates the probable number of shares of common stock that will be granted until the achievement of the performance goals is known.
	The date of grant is the date at which the Company and the employee reach a mutual understanding of the key terms and conditions of the award, appropriate approvals are received by approval by the board of directors and the Company becomes contingently obligated to issue equity instruments to the employee who renders the requisite service.
	The Company is required to estimate potential forfeitures of stock grants and adjust recorded compensation cost accordingly. The estimate of forfeitures is based on historical experience and is adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from the prior estimates. Changes in estimated forfeitures will be recognized in the period of change and will impact the amount of stock-based compensation expense to be recognized in future periods.
	All stock option awards to non-employees are accounted for at the fair value of the consideration received or the fair value of the equity instrument issued, as calculated using the Black-Scholes option-pricing model. The measurement of stock-based compensation for non-employees is subject to periodic adjustments as the options vest, and the expense is recognized over the period services are rendered.
Income Taxes	Income Taxes
	The Company accounts for income taxes under the asset and liability method, which requires the recognition of taxes payable or refundable for the current year, and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. The measurement of current and deferred tax liabilities and assets is based on provisions of the enacted tax law; the effects of future changes in tax laws or rates are not anticipated. Valuation allowances are established when necessary to reduce deferred tax assets to the amount that the Company believes is more likely than not to be realized. The Company’s determination of its valuation allowance is based upon a number of assumptions, judgments and estimates, including forecasted earnings, future taxable income and the relative proportions of revenue and income before taxes in the various jurisdictions in which it operates.
	The Company operates in various tax jurisdictions and is subject to audit by various tax authorities. Tax positions are based upon their technical merits, relevant tax law and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax positions. A tax position is only recognized in the financial statements if it is “more likely than not” to be sustained based solely on its technical merits as of the reporting date. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments that could result in recognition of additional tax benefits or additional charges to the tax provision and may not accurately reflect actual outcomes. The Company has a policy to classify accrued interest and penalties associated with uncertain tax positions together with the related liability, and the expenses incurred related to such accruals are included in the provision for income taxes.
Comprehensive Income	Comprehensive Income
	Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes certain changes in equity that are excluded from net income, specifically unrealized gains (losses) on available-for-sale investments. Except for net realized loss on investments which was not significant, there were no reclassifications out of accumulated other comprehensive income (loss) that affected net income during the years ended December 31, 2014 and 2013.
Geographical Information	Geographical Information
	The Company is domiciled in the United States and had no international operations or sales to customers outside of the United States for the years ended December 31, 2014, 2013 and 2012.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 also requires significantly expanded disclosures about revenue recognition. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. The Company has not yet developed an expectation of the impact that adoption will have on its consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”), which provides guidance on determining when and how reporting entities must disclose going-concern uncertainties in their financial statements. ASU 2014-15 requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date of issuance of the entity’s financial statements (or within one year after the date on which the financial statements are available to be issued, when applicable). Further, an entity must provide certain disclosures if there is “substantial doubt about the entity’s ability to continue as a going concern.” ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods thereafter; early adoption is permitted. The Company does not believe that adoption of ASU 2014-15 will have a material impact on its consolidated financial statements.
Correction of Immaterial Errors	Correction of Immaterial Errors
	During 2013 and the first three quarters of 2014, in preparing its quarterly and annual tax provisions, the Company incorrectly excluded a portion of compensation to the Company’s executive officers as nondeductible for income tax purposes under Section 162(m) of the Internal Revenue Code. During the fourth quarter of 2014, management determined that such compensation was, in fact, deductible and should have been included in the computation of the Company’s historical income tax computations. The Company assessed the materiality of this misstatement on prior periods’ financial statements in accordance with SEC’s Staff Accounting Bulletin ("SAB") No. 99, Materiality, codified in ASC 250, ("ASC 250"), Presentation of Financial Statements, and concluded that the misstatement was not material to any prior annual or interim periods, but the cumulative adjustment necessary to correct the classification would be material to the three months ended December 31, 2014. In accordance with ASC 250 (SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements), the financial statements as of December 31, 2013 and for the year ended December 31, 2013, which are presented herein, have been corrected. The financial statements have also been revised to reflect the correction of certain other previously uncorrected immaterial prior period errors.
	The following tables summarize the previously reported and corrected amounts of the impacted balances presented in the accompanying consolidated financial statements (in thousands except per share data).
