Accounting Policies [Abstract]	'
Basis of Presentation and Significant Accounting Policies	'
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2013, which was filed with the SEC on March 13, 2014 (“2013 Form 10-K”).
	The condensed consolidated balance sheet as of December 31, 2013, included herein, was derived from the audited financial statements as of that date but does not include all disclosures, including notes required by GAAP.
	In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial positions, results of operations and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2014 or any future period.
	Principles of Consolidation
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
	Certain reclassifications have been made to prior period amounts to conform to current period presentation. Such reclassifications have no effect on revenues, income from operations or net income as previously reported.
	Use of Estimates
	The preparation of condensed consolidated financial statements in conformity with 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. Actual results could differ from those estimates.
	Significant Accounting Policies
	Our significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements in our 2013 Form 10-K. There have been no significant changes to these policies.
	Other Income, Net
	Other income, net consisted of the following:
		Three Months ended March 31,
		2014		2013
		(in thousands)
	Interest income	122		163
	Net realized gain (loss) on investments	1		(1	)
	Interest expense	(23	)	(41	)
	Total other income, net	100		121
	Comprehensive Income
	Comprehensive income consists of net income and other comprehensive loss. Other comprehensive loss includes certain changes in equity that are excluded from net income, specifically unrealized losses on available-for-sale investments. Except for net realized gain (loss) on investments which was not significant, there were no reclassifications out of accumulated other comprehensive income (“AOCI”) that affected net income during the three months ended March 31, 2014 and 2013.
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-11, Topic 740 - Income Taxes (“ASU 2013-11”), which provides guidance to improve the presentation of an unrecognized benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We adopted ASU 2013-11 on January 1, 2014 and this adoption did not have a material impact on our consolidated financial statements.

Net Income (Loss) Per Share of Common Stock	3 Months Ended

Earnings Per Share [Abstract]	'
Net Income (Loss) 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 shares attributable to the assumed exercise of stock options, restricted stock unit awards (“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:
		Three Months ended March 31,
		2014			2013
		(in thousands, except share and per share amounts)
	Net income	$	782		$	3,913
	Basic shares:
	Weighted average common shares outstanding	27,339,394			26,166,290
	Diluted shares:
	Weighted average shares used to compute basic net income per share	27,339,394			26,166,290
	Effect of potentially dilutive securities:
	Employee stock options, RSUs, Performance Awards and ESPP shares	1,730,736			1,795,866
	Weighted average shares used to compute diluted net income per share	29,070,130			27,962,156
	Net income per share:
	Basic	$	0.03		$	0.15
	Diluted	$	0.03		$	0.14
	The following potential common shares were excluded from the computation of diluted net income per share, as their effect would have been anti-dilutive:
		Three Months ended March 31,
		2014		2013
	Employee stock options and awards	910,812		348,202
	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, we include 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 employee stock options and awards noted above, 90,625 and 635,483 shares underlying Performance Awards have been excluded from the dilutive shares outstanding for each of the three months ended March 31, 2014 and 2013, respectively.

Financial Instruments and Fair Value Measurements	3 Months Ended

Financial Instruments and Fair Value Measurements [Abstract]	'
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
				using inputs considered as
		March 31, 2014		Level 1			Level 2			Level 3
		(in thousands)
	Money market funds	$	15,175	$	15,175		$	—		$	—

		$	121,973	$	27,859		$	94,114		$	—
	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. We classify our money market funds 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 March 31, 2014 and December 31, 2013, the Company did not have any assets or liabilities that were valued using Level 3 inputs. For the three months ended March 31, 2014 and 2013, there were no transfers of financial instruments among Level 1, Level 2 or Level 3 classifications.
	For the three months ended March 31, 2014 and 2013, the Company recognized interest income from financial instruments of $0.1 million and $0.2 million, respectively. Gross realized gains and gross realized losses from the sale of investments were not significant during the three months ended March 31, 2014 and 2013.
	The carrying amounts, gross unrealized gains and losses and estimated fair value of cash and cash equivalents and both short and long-term investments consisted of the following:

Business Combinations [Abstract]	'
Business Combination Disclosure [Text Block]	'
	On January 15, 2014, the Company acquired substantially all the assets of ARG Interactive, LLC (dba MortgageCEO), a software as a service ("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 transactions costs, which were insignificant, in the period in which they were incurred.
	The total purchase price was $5.0 million, 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 price to cover closing capital settlement adjustments and any indemnity claims. Any unused portion of the holdback funds will be paid on July 15, 2015.
	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 price	$	5,020
	Developed technology consists of the technology underlying MortgageCEO's existing products. The value of the developed technology was determined by discounting the estimated net future cash flows of these products. The Company is amortizing the developed technology on a straight-line basis over an estimated life of 5 years.
	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. The fair value of the customer relationships was determined by discounting the estimated net future cash flows from the customer contracts. The Company is amortizing customer relationships on a straight-line basis over an estimated life of 5 years.
	Trade name represents the right to use the MortgageCEO name. The fair value of the trade name was determined by estimating a benefit from owning the asset rather than paying a royalty to a third party for the use of the asset. The Company is amortizing the asset on a straight-line basis over an estimated life of 2 years.
	Goodwill represents the excess of the purchase price over the fair value of the identifiable assets acquired and is not deductible for tax purposes. 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 income for the three months ended March 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 three months ended March 31, 2014 and 2013 were not significant.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	We compute our interim provision for income taxes by applying the estimated annual effective tax rate to the year-to-date income from recurring operations and adjust the provision for discrete tax items recorded in the period. We evaluate and update our estimated annual effective income tax rate on a quarterly basis. The estimated effective tax rate for the three months ended March 31, 2014 and 2013 was 33.4% and 26.6%, respectively.
	The difference between the federal statutory rate of 35% and our estimated effective tax rate for the three months ended March 31, 2014 was primarily due to our state income tax provision and non-deductible stock-based compensation expenses and limitations of tax deductions under Internal Revenue Code ("IRC") Section 162(m) for compensation paid to our executive officers, offset by the domestic production activities deduction under IRC Section 199 and disqualifying dispositions of stock-based awards.
	Our tax positions are subject to income tax audits by multiple tax jurisdictions. We account for uncertain tax positions and believe that we have provided adequate reserves for our unrecognized tax benefits for all tax years still open for assessment. We also believe that we do not have any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within the next twelve months.
	We have a policy to classify accrued interest and penalties associated with uncertain tax positions together with the related liability in the balance sheet, and to include the expenses incurred related to such accruals in the provision for income taxes. During the three months ended March 31, 2014, we included interest and penalties of $20 thousand in the provision for income taxes.

	Legal Proceedings
	On March 25, 2011, Industry Access Incorporated (“Industry Access”) filed a patent infringement lawsuit against us and another defendant in the U.S. District Court for the Central District of California. The complaint alleges, among other things, that certain aspects of our Encompass loan management software system and related operations infringe a single patent, and seeks declaratory relief and unspecified damages from the defendants, including enhanced damages for willful infringement and reasonable attorneys’ fees. On June 24, 2011, the Court issued an order requiring plaintiff to serve the complaint on all defendants within three days of the order. On June 28, 2011, plaintiff served us with the complaint and we filed its answer on August 5, 2011 denying all material allegations of the complaint. On November 18, 2011 the other defendant filed with the United States Patent and Trademark Office (the “PTO”) a request for ex parte reexamination of Industry Access’ US Patent No 7,769,681, which the PTO granted on February 14, 2012. On December 15, 2011, we filed a motion to stay the litigation pending the reexamination, which the Court granted on February 28, 2012. On October 9, 2012, the PTO issued the reexamination certificate. The Court granted a motion to dismiss the other defendant from this action on April 7, 2013 and lifted the stay on April 11, 2013. The parties are in the claims construction phase of the litigation with a claim construction hearing that was scheduled for December 2, 2013. Discovery is ongoing and the trial has been rescheduled for December 2014 as further discussed below.
	On March 19, 2013, Industry Access filed a second patent infringement lawsuit against us in the U.S. District Court for the Central District of California. The complaint alleges, 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, asserted in the lawsuit described above. Plaintiff is seeking unspecified damages. On June 12, 2013, we filed a motion to dismiss or, in the alternative, to transfer this case to the Northern District of California, which the Court denied on September 18, 2013. Trial is set for December 2014.
	On September 12, 2013, we filed a motion to relate and consolidate the two Industry Access lawsuits so that all of Industry Access’ related patent infringement claims would be heard before the same judge on the same schedule.  Industry Access responded to this motion on October 11, 2013.  The Court granted our motion to consolidate on October 31, 2013.   The Court has scheduled the claim construction hearing for June 2, 2014.  Trial is set for December 2014.
	We believe that we have substantial and meritorious defenses in the newly consolidated case and, if similar claims are pursued, we intend to defend these and similar claims vigorously.
	We are also subject to various other legal proceedings and claims arising in the ordinary course of business. With respect to these matters and the litigations described above, we cannot predict the ultimate outcome of these legal proceedings and the amounts and ranges of potential damages associated with such proceedings cannot be estimated or assessed. An unfavorable outcome of these or the litigation could materially adversely affect our business, financial condition and results of operations.

	Stock options granted during the three months ended March 31, 2014 were made under the 2011 Plan. There were no grants under the 2009 Plan during the three months ended March 31, 2014.
	Intrinsic value of an option is the difference between the fair value of our common stock at the time of exercise and the exercise price to be paid. The aggregate intrinsic value for options outstanding at March 31, 2014 in the table above represents the total intrinsic value, based on our closing stock price of $28.84 as of March 31, 2014, which would have been received by option holders had all option holders exercised their in-the-money options as of that date. Options outstanding that are expected to vest are net of estimated future option forfeitures.
	Following is additional information pertaining to our stock option activity:
		Three Months ended March 31,

	As of March 31, 2014, total unrecognized stock-based compensation expense related to unvested stock options, adjusted for estimated forfeitures, was $13.5 million and is expected to be recognized over a weighted average period of 2.5 years.
	Restricted Stock Units and Performance Awards
	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 between zero and 4 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. 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. Of the issued shares, 25% were vested upon issuance and the remaining shares will vest 25% on each of the first three anniversaries of the Determination Date, subject to the continuous employment of the participant through such dates. No forfeitures are expected.
	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. No forfeitures are expected.
	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 March 31, 2014, we expect that each award will convert to 1.45 shares of common stock on the 2014 Award Determination Date. No forfeitures are expected.

RSUs released during the three months ended March 31, 2014 and 2013 had an aggregate intrinsic value of $98 thousand and $62 thousand, respectively and had an aggregate grant-date fair value of $28 thousand and $28 thousand, respectively. There were no Performance Awards released during the three months ended March 31, 2014 and 2013. The number of RSUs released includes shares that we withheld on behalf of employees to satisfy the minimum statutory tax withholding requirements.

	We operate in one industry—mortgage-related software and services. Our chief operating decision makers are our chief executive officer and president and chief operating officer, who make decisions about resource allocation and review financial information presented on a consolidated basis. Accordingly, we have determined that we have a single reporting segment and operating unit structure, specifically technology-enabled solutions to help streamline and automate the residential mortgage origination process for our network participants.
	We are organized primarily on the basis of service lines. Supplemental disclosure of revenues by type is as follows:

	In the Notes to our condensed consolidated financial statements on our Quarterly Report on Form 10-Q for the quarter ended March 31, 2013, we included all revenues from professional services in on-premise revenues in our disclosure related to revenues by type. For the quarter ended March 31, 2014, we included professional services revenues in either on-demand revenues or on-premise revenues as determined by the related service or software license revenue. We have retrospectively reclassified our disclosure of on-demand and on-premise revenues for the three months ended March 31, 2013 in order to conform to the current presentation.

	Principles of Consolidation
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
	Certain reclassifications have been made to prior period amounts to conform to current period presentation. Such reclassifications have no effect on revenues, income from operations or net income as previously reported.
Use of Estimates, Policy [Policy Text Block]	'
	Use of Estimates
	The preparation of condensed consolidated financial statements in conformity with 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. Actual results could differ from those estimates.
Significant Accounting Policies [Text Block]	'
	Significant Accounting Policies
	Our significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements in our 2013 Form 10-K. There have been no significant changes to these policies.
Comprehensive Income [Policy Text Block]	'
	Comprehensive Income
	Comprehensive income consists of net income and other comprehensive loss. Other comprehensive loss includes certain changes in equity that are excluded from net income, specifically unrealized losses on available-for-sale investments. Except for net realized gain (loss) on investments which was not significant, there were no reclassifications out of accumulated other comprehensive income (“AOCI”) that affected net income during the three months ended March 31, 2014 and 2013

	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-11, Topic 740 - Income Taxes (“ASU 2013-11”), which provides guidance to improve the presentation of an unrecognized benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We adopted ASU 2013-11 on January 1, 2014 and this adoption did not have a material impact on our consolidated financial statements.
