Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company records cash equivalents at cost, which approximates fair market value. The carrying values for receivables from clients, unbilled receivables, accounts payable, deferred revenue and other accrued liabilities reasonably approximate fair market value due to the nature of the financial instrument and the short-term maturity of these items. The Company records bank debt, if any, as of the period end date based on the effective borrowing rate and repayment terms when originated. The Company had $33.0 million in bank debt outstanding as of June 30, 2019 and $21.6 million in bank debt outstanding as of December 31, 2018. The Company believes the carrying value of the bank debt approximates its fair value. The Company considers the factors used in determining the fair value of this debt to be Level 3 inputs (significant unobservable inputs). The Company had $4.0 million of business acquisition obligations as of June 30, 2019, and $4.2 million of business acquisition obligations as of December 31, 2018. The Company's business acquisition obligations represent the estimated fair value of the deferred consideration and projected earnout payments due as of the end of the reporting period. The Company determines the estimated fair value of business acquisition obligations based on its projections of future revenue and profits or other factors used in the calculation of the ultimate payment(s) to be made. The discount rate that the Company uses to value the liability is based on specific business risk, cost of capital, and other factors. The Company considers these factors to be Level 3 inputs (significant unobservable inputs). The business acquisition obligations were subsequently settled in July 2019. The Company states certain assets at fair value on a nonrecurring basis as required by GAAP. Generally, these assets are recorded at fair value on a nonrecurring basis as a result of impairment charges.
