Summary of Significant Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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 periods. Actual results could differ from those estimates, and such differences could be material to the financial statements.
Revenue Recognition	Revenue Recognition Service revenues are primarily derived from professional services provided on a time and materials basis. For time and material contracts, service revenues are recognized and billed by multiplying the number of hours expended in the performance of the contract by the established billing rates. For fixed fee projects, service revenues are generally recognized using an input method based on the ratio of hours expended to total estimated hours. Amounts invoiced and collected in excess of revenues recognized are classified as deferred revenues. In conjunction with services provided, the Company occasionally receives referral fees under partner programs. These referral fees are recorded when earned within service revenues. Revenues from software and hardware sales are generally recorded on a gross basis considering the Company's role as a principal in the transaction. Revenues from sales of third-party software-as-a-service arrangements where the Company is not the primary obligor are recorded on a net basis. On many projects the Company is also reimbursed for out-of-pocket expenses including travel and other project-related expenses. These reimbursements are included as a component of revenues. We did not realize any profit on reimbursable expenses. Unbilled revenues represent the project time and expenses that have been incurred, but not yet billed to the client, prior to the end of the fiscal period. For time and materials projects, the client is invoiced for the amount of hours worked multiplied by the billing rates as stated in the contract. For fixed fee arrangements, the client is invoiced according to the agreed-upon schedule detailing the amount and timing of payments in the contract. Clients are typically billed monthly for services provided during that month, but can be billed on a more or less frequent basis as determined by the contract. If the time and expenses are worked/incurred and approved at the end of a fiscal period and the invoice has not yet been sent to the client, the amount is recorded as unbilled revenue once the Company verifies all other revenue recognition criteria have been met. Revenues are recognized when the following criteria are met: (1) persuasive evidence of the customer arrangement exists; (2) fees are fixed and determinable; (3) delivery and acceptance have occurred; and (4) collectability is deemed probable. The Company's policy for revenue recognition in instances where multiple deliverables are sold contemporaneously to the same customer is in accordance with FASB Accounting Standards Codification ("ASC") Subtopic 985-605, Software – Revenue Recognition, ASC Subtopic 605-25, Revenue Recognition – Multiple-Element Arrangements, and ASC Section 605-10-S99 (Staff Accounting Bulletin Topic 13, Revenue Recognition). Specifically, if the Company enters into contracts for the sale of services and software or hardware, then the Company evaluates whether each element should be accounted for separately by considering the following criteria: (1) whether the deliverables have value to the client on a stand-alone basis; and (2) whether delivery or performance of the undelivered item or items is considered probable and substantially in the control of the Company (only if the arrangement includes a general right of return related to the delivered item). Further, for sales of software and services, the Company also evaluates whether the services are essential to the functionality of the software and if it has fair value evidence for each deliverable. If the Company has concluded that the separation criteria are met, then it accounts for each deliverable in the transaction separately, based on the relevant revenue recognition policies. Generally, all deliverables of the Company's multiple element arrangements meet these criteria and are accounted for separately, with the arrangement consideration allocated among the deliverables using vendor specific objective evidence of the selling price. As a result, the Company generally recognizes software and hardware sales upon delivery to the customer and services consistent with the policies described herein. Further, delivery of software and hardware sales, when sold contemporaneously with services, can generally occur at varying times depending on the specific client project arrangement. Delivery of services generally occurs over a period of time consistent with the timeline as outlined in the client contract. There are no significant cancellation or termination-type provisions for the Company's software and hardware sales. Contracts for professional services provide for a general right, to the client or the Company, to cancel or terminate the contract within a given period of time (generally 10 to 30 days' notice is required). The client is responsible for any time and expenses incurred up to the date of cancellation or termination of the contract. The Company may provide multiple services under the terms of an arrangement, and are required to assess whether one or more units of accounting are present. Service fees are typically accounted for as one unit of accounting, as fair value evidence for individual tasks or milestones is not available. The Company follows the guidelines discussed above in determining revenues; however, certain judgments and estimates are made and used to determine revenues recognized in any accounting period. If estimates are revised, material differences may result in the amount and timing of revenues recognized for a given period. Revenues are presented net of taxes assessed by governmental authorities. Sales taxes are generally collected and subsequently remitted on all software and hardware sales and certain services transactions as appropriate.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts An allowance for doubtful accounts is based upon specific identification of likely and probable losses. Each accounting period, accounts receivable is evaluated for risk associated with a client's inability to make contractual payments, historical experience, and other currently available information.
Stock-Based Compensation	Stock-Based Compensation Stock-based compensation is accounted for in accordance with ASC Topic 718, Compensation – Stock Compensation ("ASC Topic 718"). Under this method, the Company recognizes share-based compensation ratably using the straight-line attribution method over the requisite service period. In addition, pursuant to ASC Topic 718, the Company is required to estimate the amount of expected forfeitures when calculating share-based compensation, instead of accounting for forfeitures as they occur.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with ASC Subtopic 740-10, Income Taxes ("ASC Subtopic 740-10"), and ASC Section 740-10-25, Income Taxes – Recognition ("ASC Section 740-10-25"). ASC Subtopic 740-10 prescribes the use of the asset and liability method whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Deferred tax assets are subject to tests of recoverability. A valuation allowance is provided for such deferred tax assets to the extent realization is not judged to be more likely than not. ASC Subtopic 740-10-25 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC Subtopic 740-10-25 also provides guidance on derecognition, classification, treatment of interest and penalties, and disclosure of such positions.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of all cash balances and liquid investments with original maturities of three months or less.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost. Depreciation of property and equipment is computed using the straight-line method over the useful lives of the assets (generally one to seven years). Leasehold improvements are amortized over the shorter of the life of the lease or the estimated useful life of the assets.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess purchase price over the fair value of net assets acquired, or net liabilities assumed, in a business combination. In accordance with ASC Topic 350, Intangibles – Goodwill and Other ("ASC Topic 350"), the Company performs an annual impairment review in the fourth quarter and more frequently if events or changes in circumstances indicate that goodwill might be impaired. ASC Topic 350 permits an assessment of qualitative factors to determine whether it is more likely than not that the fair value is less than the carrying amount of the Company before applying the two-step goodwill impairment test. If it is more likely than not that the fair value is less than the carrying amount of the Company, the two-step goodwill impairment test will be conducted. The first step screens for impairment and, when impairment is indicated, a second step is employed to measure the impairment. Based upon the Company's qualitative assessment, it is more likely than not that the fair value of the Company is greater than its carrying amount. No impairment charges were recorded for 2015, 2014 or 2013. Other intangible assets include customer relationships, non-compete arrangements, trade names, customer backlog, and internally developed software, which are being amortized over the assets' estimated useful lives using the straight-line method. Estimated useful lives range from less than one year to ten years. Amortization of customer relationships, non-compete arrangements, trade names, customer backlog, and internally developed software is considered an operating expense and is included in "Amortization" in the accompanying Consolidated Statements of Operations. The Company periodically reviews the estimated useful lives of its identifiable intangible assets, taking into consideration any events or circumstances that might result in a lack of recoverability or revised useful life.
Financial Instruments	Financial Instruments Cash equivalents, accounts receivable, accounts payable, and other accrued liabilities are stated at amounts which approximate fair value due to the near term maturities of these instruments. The Company's long-term debt balance approximates fair market value. The Company, when deemed appropriate, uses derivatives as a risk management tool to mitigate the potential impact of foreign currency exchange rate risk. Both the gain or loss on derivatives not designated as hedging instruments and the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. All derivatives are carried at fair value in the consolidated balance sheets. See Note 11, Financial Instruments, for additional information regarding our derivative financial instruments.
Treasury Stock	Treasury Stock The Company uses the cost method to account for repurchases of its own stock.
Segment and Geographic Information	Segment and Geographic Information The Company operates as one reportable operating segment according to ASC Topic 280, Segment Reporting, which establishes standards for the way that business enterprises report information about operating segments. The chief operating decision maker formulates decisions about how to allocate resources and assess performance based on consolidated financial results. The Company also has one reporting unit for purposes of the goodwill impairment analysis discussed above. Approximately 98% of the Company's revenues were derived from clients in the United States during the year ended December 31, 2015 as compared to 99% for each of the years ended December 31, 2014 and 2013. Less than 2% and 1% of the Company's non-current assets were located outside the United States for each of the years ended December 31, 2015 and 2014, respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU No. 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. On April 1, 2015, the FASB voted to propose to defer the effective date of ASU 2014-09 by one year. The new standard is to become effective for the Company on January 1, 2018. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this update. This standard is to become effective for the Company on January 1, 2016 and requires that the Company use a retrospective approach. The Company does not expect the adoption of ASU 2015-03 to have a material impact on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement, which provides specific guidance on the recognition of fees paid by a customer for cloud computing arrangements as either the acquisition of a software license or a service contract. This standard is to become effective for the Company on January 1, 2016. The Company does not expect the adoption of ASU 2015-05 to have a material impact on the Company's consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, which eliminates the requirement for an acquirer to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after the acquisition date. This standard is to become effective for the Company on January 1, 2016. The Company does not expect the adoption of ASU 2015-16 to have a material impact on the Company's consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes, which will require entities with a classified balance sheet to present all deferred tax assets and liabilities as noncurrent. This standard is to become effective for the Company on January 1, 2017 and may be applied prospectively or retrospectively. Early adoption of the standard is permitted. The Company early adopted this standard retrospectively on December 31, 2015. The adoption of this standard resulted in a reclassification of current deferred tax assets which caused a $0.7 million reduction to other current assets and a corresponding $0.7 reduction to other non-current liabilities on the Company's balance sheet as of December 31, 2014, but had no effect on the Company's results of operations, financial condition or cash flows. In February 2016, the FASB issued ASU No. 2016-02, Leases, which supersedes ASC Topic 840, Leases, and creates a new topic, ASC Topic 842, Leases. This update requires lessees to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12 months on its balance sheet. The update also expands the required quantitative and qualitative disclosures surrounding leases. This standard is to become effective for the Company on January 1, 2019, with earlier application permitted. This update will be applied using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating the effect of this update on its consolidated financial statements.
