Summary of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	Principles of Consolidation
	These unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company is not the primary beneficiary of, nor does it have a controlling financial interest in, any variable interest entity. Accordingly, the Company has not consolidated any variable interest entity.
	Interim Unaudited Consolidated Financial Information
	The accompanying unaudited consolidated financial statements and footnotes have been prepared in accordance with GAAP as contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (the “Codification” or “ASC”) for interim financial information, and with Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, changes in stockholders’ equity and cash flows. The results of operations for the three- and nine-month periods ended September 30, 2014 are not necessarily indicative of the results for the full year or the results for any other future period. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements and related footnotes for the year ended December 31, 2013 included in the Company’s annual report on Form 10-K.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Such estimates include revenue recognition and the customer relationship period, allowances for doubtful accounts and returns, valuations of deferred income taxes, long-lived assets, warrants, the useful lives of assets, capitalizable software development costs and the related amortization, contingent consideration, stock-based compensation, annual bonus attainment, acquired intangibles, and goodwill. Determination of these transactions and account balances are based on the Company’s estimates and judgments. These estimates are based on the Company’s knowledge of current events and actions it might undertake in the future as well as on various other assumptions that it believes to be reasonable. Actual results could differ from these estimates.
	Concentrations of Credit Risk
	The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash equivalents and accounts receivable. All of the Company’s cash and cash equivalents are held at financial institutions that management believes to be of high credit quality. The bank deposits of the Company might, at times, exceed federally insured limits and are generally uninsured and uncollateralized. The Company has not experienced any losses on cash and cash equivalents to date.
	To manage accounts receivable risk, the Company evaluates the creditworthiness of its customers and maintains an allowance for doubtful accounts. Accounts receivable were unsecured and were derived from revenue earned from customers located in the United States. Accounts receivable from one customer, Aetna, represented 10.9% and 11.3%, of the total accounts receivable at September 30, 2014 and December 31, 2013, respectively. No customer represented more than 10% of total revenue for the three- and nine- month periods ended September 30, 2014 and 2013.
	Accounts Receivable and Allowance for Doubtful Accounts and Returns
	Accounts receivable is stated at realizable value, net of allowances for doubtful accounts and returns. The Company utilizes the allowance method to provide for doubtful accounts based on management’s evaluation of the collectability of amounts due and other relevant factors. Bad debt expense is recorded in general and administrative expense on the unaudited consolidated statements of operations and comprehensive loss. The Company bases its estimate on historical collection experience and a review of the current status of accounts receivable. Historically, actual write-offs for uncollectible accounts have not significantly differed from the Company’s estimates. The Company removes recorded receivables and the associated allowances when they are deemed permanently uncollectible. However, higher than expected bad debts could result in write-offs that are greater than the Company’s estimates. The allowance for doubtful accounts was $15 and $10 as of September 30, 2014 and December 31, 2013, respectively.
	The allowances for returns are accounted for as reductions of revenue and are estimated based on the Company’s periodic assessment of historical experience and trends. The Company considers factors such as the time lag since the initiation of revenue recognition, historical reasons for adjustments, new customer volume, complexity of billing arrangements, timing of software availability, and past due customer billings. The allowance for returns was $1,095 and $800 as of September 30, 2014 and December 31, 2013, respectively.
	Capitalized Software Development Costs
	The Company capitalizes certain costs related to its software developed or obtained for internal use. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Internal and external costs incurred during the application development stage, including upgrades and enhancements representing modifications that will result in significant additional functionality, are capitalized. Software maintenance and training costs are expensed as incurred. Capitalized costs are recorded as part of property and equipment and are amortized on a straight-line basis over the software’s estimated useful life. The Company evaluates the useful lives of these assets on at least an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
	In the three months ended September 30, 2014 and 2013, the Company capitalized software development costs of $562 and $971, and amortized capitalized software development costs of $751 and $662, respectively. In the nine months ended September 30, 2014 and 2013, the Company capitalized software development costs of $1,499 and $2,350, and amortized capitalized software development costs of $2,214 and $1,904, respectively. The net book value of capitalized software development costs was $3,455 and $4,170 at September 30, 2014 and December 31, 2013, respectively.
	Comprehensive Loss
	The Company’s net loss equals comprehensive loss for all periods presented, as the Company has no components of other comprehensive income (loss).
	Recently Adopted Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists”. ASU 2013-11 allows an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with one exception. That exception states that, to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance did not have an impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09 “Revenue from Contracts with Customers”, which amends the revenue recognition requirements in the FASB Accounting Standards Codification (ASC). This statement requires that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The statement shall be applied using one of two methods: retrospectively to each prior reporting period presented, or retrospectively with the cumulative effect of initially applying this statement recognized at the date of initial application. The Company has not yet determined which method it will apply. This statement is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently evaluating the impact of this guidance on the Company’s consolidated financial position and results of operations.

Fair Value Measurement	'
	4. Fair Value Measurement
	The carrying amounts of certain of the Company’s financial instruments, including cash and cash equivalents, net accounts receivable, accounts payable and other accrued liabilities, and accrued compensation and benefits, approximate fair value due to their short-term nature. The carrying value of the Company’s notes payable, capital leases and financing obligations for support contracts approximates fair value, considering the borrowing rates currently available to the Company for financing arrangements with similar terms and credit risks.
	The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. The hierarchy requires the Company to use observable inputs when available, and to minimize the use of unobservable inputs when determining fair value. The three tiers are defined as follows:
	Level 1.		Quoted prices (unadjusted) in active markets for identical assets or liabilities.
	Level 2.		Other inputs that are directly or indirectly observable in the marketplace.
	Level 3.		Unobservable inputs for which there is little or no market data, which require the Company to develop its own assumptions.
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	The Company evaluates its financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level to classify them for each reporting period. This determination requires significant judgments to be made.
	The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis using the above categories, as of September 30, 2014 and December 31, 2013.

	8. Stock-based Compensation
	Restricted Stock Units
	During July 2014, the Company granted 89,746 Restricted Stock Units (RSUs) to employees with an aggregate grant date fair value of $4,259. These RSUs vest in equal annual installments generally over 4 years from the grant date. The Company amortizes the fair value of the stock subject to the RSUs at the time of grant on a straight-line basis over the period of vesting. The Company recognizes the income tax benefits resulting from vesting of RSUs in the period they vest, to the extent the compensation expense has been recognized.
	In June 2014, the Board of Directors of the Company established a compensation program for the Company’s independent directors. Each independent director will receive an annual retainer of $150, payable at the director’s election either 50% in cash and 50% in RSUs, or 100% in RSUs. The RSUs vest on the first anniversary of the Company’s annual stockholders meeting held in the year of the grant, or, if earlier, immediately prior to the subsequent year’s annual stockholders meeting. Pursuant to this program, the Company granted four directors RSUs for an aggregate of 44,282 shares of common stock. Aggregate grant date fair value of these awards is $1,564. Estimated remaining expense in the amounts of $186, $587, $462, and $211 will be recognized in 2014, 2015, 2016, and 2017, respectively, as General and Administrative expense.
	During April 2014, the Company granted 264,359 RSUs to employees with an aggregate grant date fair value of $12,663. These RSUs vest in equal annual installments, generally over 4 years from the grant date. The fair value of the stock subject to the RSUs at the time of grant is amortized based on a straight-line basis over the period of vesting. Income tax benefits resulting from vesting of RSUs are recognized in the period the units are vested and exchanged for common stock to the extent the compensation expense has been recognized.
	Warrants
	During 2009, in connection with a new five-year contract executed with a major customer, the Company issued a warrant to the customer for the right to purchase 500,000 shares of common stock at $5.48 per share. The warrant was issued from the stock option pool of shares approved by the Board of Directors. The warrant had a term of 10 years. The customer was originally entitled to exercise the warrant in its entirety in 9.5 years, with earlier exercise rights under certain conditions. The original terms of the warrant also provided that, in the event the customer cancelled the contract prior to the end of its five-year term, one-half of the warrant would be forfeited. In March 2013, the Company accelerated the vesting of the warrant, making it fully exercisable. As a result of the modification, quarterly remeasurement of the warrant was no longer required. For the three and nine months ended September 30, 2014 and 2013, the reduction to revenue related to the warrant was $223 and $669, respectively, in each year.
	On March 28, 2014, the customer exercised the warrant through a cashless exercise in accordance with the warrant’s terms. The Company issued 455,521 shares to satisfy its obligation under the warrant.

Segments and Geographic Information	'
	10. Segments and Geographic Information
	Operating segments are defined as components of an enterprise for which discrete financial information is available that is evaluated regularly by the chief operating decision maker (“CODM”) for purposes of allocating resources and evaluating financial performance. The Company’s CODM, the Chief Executive Officer, reviews financial information presented on a consolidated basis, accompanied by information about operating segments, for purposes of allocating resources and evaluating financial performance.
	The Company’s reportable segments are based on the type of customer. The Company determined its operating segments to be: Employer, which derives substantially all of its revenue from customers that use the Company’s services for the provision of benefits to their employees, and administrators acting on behalf of employers; and Carrier, which derives substantially all of its revenue from insurance companies that provide coverage at their own risk.
	The Company evaluates the performance of its operating segments based on operating income. The Company does not allocate interest income, interest expense or income tax expense by segment. Accordingly, the Company does not report such information. Additionally, Employer and Carrier segments share the majority of the Company’s assets. Therefore, no segment asset information is evaluated or reported.

Principles of Consolidation	'
	Principles of Consolidation
	These unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company is not the primary beneficiary of, nor does it have a controlling financial interest in, any variable interest entity. Accordingly, the Company has not consolidated any variable interest entity.
Interim Unaudited Consolidated Financial Information	'
	Interim Unaudited Consolidated Financial Information
	The accompanying unaudited consolidated financial statements and footnotes have been prepared in accordance with GAAP as contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (the “Codification” or “ASC”) for interim financial information, and with Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, changes in stockholders’ equity and cash flows. The results of operations for the three- and nine-month periods ended September 30, 2014 are not necessarily indicative of the results for the full year or the results for any other future period. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements and related footnotes for the year ended December 31, 2013 included in the Company’s annual report on Form 10-K.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Such estimates include revenue recognition and the customer relationship period, allowances for doubtful accounts and returns, valuations of deferred income taxes, long-lived assets, warrants, the useful lives of assets, capitalizable software development costs and the related amortization, contingent consideration, stock-based compensation, annual bonus attainment, acquired intangibles, and goodwill. Determination of these transactions and account balances are based on the Company’s estimates and judgments. These estimates are based on the Company’s knowledge of current events and actions it might undertake in the future as well as on various other assumptions that it believes to be reasonable. Actual results could differ from these estimates.
Concentrations of Credit Risk	'
	Concentrations of Credit Risk
	The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash equivalents and accounts receivable. All of the Company’s cash and cash equivalents are held at financial institutions that management believes to be of high credit quality. The bank deposits of the Company might, at times, exceed federally insured limits and are generally uninsured and uncollateralized. The Company has not experienced any losses on cash and cash equivalents to date.
	To manage accounts receivable risk, the Company evaluates the creditworthiness of its customers and maintains an allowance for doubtful accounts. Accounts receivable were unsecured and were derived from revenue earned from customers located in the United States. Accounts receivable from one customer, Aetna, represented 10.9% and 11.3%, of the total accounts receivable at September 30, 2014 and December 31, 2013, respectively. No customer represented more than 10% of total revenue for the three- and nine- month periods ended September 30, 2014 and 2013
Accounts Receivable and Allowance for Doubtful Accounts and Returns	'
	Accounts Receivable and Allowance for Doubtful Accounts and Returns
	Accounts receivable is stated at realizable value, net of allowances for doubtful accounts and returns. The Company utilizes the allowance method to provide for doubtful accounts based on management’s evaluation of the collectability of amounts due and other relevant factors. Bad debt expense is recorded in general and administrative expense on the unaudited consolidated statements of operations and comprehensive loss. The Company bases its estimate on historical collection experience and a review of the current status of accounts receivable. Historically, actual write-offs for uncollectible accounts have not significantly differed from the Company’s estimates. The Company removes recorded receivables and the associated allowances when they are deemed permanently uncollectible. However, higher than expected bad debts could result in write-offs that are greater than the Company’s estimates. The allowance for doubtful accounts was $15 and $10 as of September 30, 2014 and December 31, 2013, respectively.
	The allowances for returns are accounted for as reductions of revenue and are estimated based on the Company’s periodic assessment of historical experience and trends. The Company considers factors such as the time lag since the initiation of revenue recognition, historical reasons for adjustments, new customer volume, complexity of billing arrangements, timing of software availability, and past due customer billings. The allowance for returns was $1,095 and $800 as of September 30, 2014 and December 31, 2013, respectively.
Capitalized Software Development Costs	'
	Capitalized Software Development Costs
	The Company capitalizes certain costs related to its software developed or obtained for internal use. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Internal and external costs incurred during the application development stage, including upgrades and enhancements representing modifications that will result in significant additional functionality, are capitalized. Software maintenance and training costs are expensed as incurred. Capitalized costs are recorded as part of property and equipment and are amortized on a straight-line basis over the software’s estimated useful life. The Company evaluates the useful lives of these assets on at least an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
	In the three months ended September 30, 2014 and 2013, the Company capitalized software development costs of $562 and $971, and amortized capitalized software development costs of $751 and $662, respectively. In the nine months ended September 30, 2014 and 2013, the Company capitalized software development costs of $1,499 and $2,350, and amortized capitalized software development costs of $2,214 and $1,904, respectively. The net book value of capitalized software development costs was $3,455 and $4,170 at September 30, 2014 and December 31, 2013, respectively.
Comprehensive Loss	'
	Comprehensive Loss
	The Company’s net loss equals comprehensive loss for all periods presented, as the Company has no components of other comprehensive income (loss).
Recently Adopted Accounting Pronouncements	'
	Recently Adopted Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists”. ASU 2013-11 allows an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with one exception. That exception states that, to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance did not have an impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09 “Revenue from Contracts with Customers”, which amends the revenue recognition requirements in the FASB Accounting Standards Codification (ASC). This statement requires that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The statement shall be applied using one of two methods: retrospectively to each prior reporting period presented, or retrospectively with the cumulative effect of initially applying this statement recognized at the date of initial application. The Company has not yet determined which method it will apply. This statement is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently evaluating the impact of this guidance on the Company’s consolidated financial position and results of operations.
