Risks and Uncertainties [Abstract]
Concentration of Credit Risk and Significant Customers	Concentration of Credit Risk and Significant CustomersCash and accounts receivable potentially expose the Company to concentrations of credit risk. Cash is placed with highly rated financial institutions. The Company provides credit, in the normal course of business, to its customers. The Company generally does not require collateral or up-front payments. The Company performs periodic credit evaluations of its customers and maintains allowances for potential credit losses. Customers can be denied access to services in the event of non-payment. During 2020, a substantial portion of the services the Company provided were built on IBM, Adobe, Oracle, and Microsoft platforms, among others, and a significant number of the Company’s clients are identified through joint selling opportunities conducted with and through sales leads obtained from the relationships with these vendors. Due to the Company’s significant fixed operating expenses, the loss of sales to any significant customer could negatively impact net income and cash flow from operations. However, the Company has remained relatively diversified, with its largest customer only representing approximately 5% of total revenues for the years ended December 31, 2020, 2019 and 2018.
