Accounting Policies [Abstract]
Basis of presentation and summary of significant accounting policies	Note 2 — Basis of presentation and summary of significant accounting policies The following is a summary of the significant accounting policies consistently applied in the preparation of the accompanying consolidated financial statements. Basis of presentation The Business Combination was accounted for as a reverse recapitalization in accordance with U.S. GAAP. Although ChaSerg was the legal acquirer, for accounting purposes, GDI was deemed to be the accounting acquirer. GDI was determined to be the accounting acquirer based on evaluation of the following facts and circumstances: • -to-day • • • • -level In conjunction with the Business Combination, outstanding shares of GDI were converted into common stock of the Company, par value $0.0001 per share, shown as a recapitalization, and the net assets of ChaSerg were acquired at historical cost, with no goodwill or other intangible assets recorded. GDI was deemed to be the predecessor of the Company, and the consolidated assets and liabilities and results of operations prior to the Closing (for the years ended December In accordance with guidance applicable to these circumstances, the equity structure has been restated in all comparative periods up to the Closing Date, to reflect the number of shares of the Company’s common stock, $0.0001 par value per share, issued to GDI shareholders in connection with the recapitalization transaction. As such, the shares and corresponding capital amounts and earnings per share related to GDI preferred and common stock prior to the Business Combination have been retroactively restated as shares reflecting the exchange ratio established in the Business Combination. Principles of consolidation The accompanying consolidated financial statements include the accounts of the Company and all of its subsidiaries that are directly or indirectly owned or controlled. Intercompany transactions and balances have been eliminated upon consolidation. Use of estimates The preparation of the consolidated financial statements in accordance with U.S. GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and such differences could be material. Significant estimates include useful lives and recoverability of property and equipment, determination of fair value, useful lives and recoverability of intangible assets and goodwill, allowances for receivables, calculation of accrued liabilities, capitalization of internally developed software, stock -based Certain significant risks and uncertainties The Company is subject to risks, including but not limited to customer concentration, concentrations of credit and foreign currency risks. Additionally, the Company has been impacted by the recent coronavirus (“COVID -19 -19 -in-place -19 -19 -19 -wide -essential -19 -term Cash and cash equivalents The Company considers cash equivalents to be highly liquid investments with original maturities of three months or less. Cash equivalents are stated at cost, which approximates fair value. At times, cash deposits with banks may exceed federally insured limits. Accounts receivable and allowance for doubtful accounts Accounts receivable, less allowance for doubtful accounts, reflect the net realizable value of receivables and approximate fair value. The Company maintains an allowance against accounts receivable for the estimated probable losses on uncollectible accounts. The allowance is based upon historical loss experience, current economic conditions within the industries the Company serves as well as determination of the specific risk related to certain customers. Accounts receivable are charged off against the reserve when, in management’s estimation, further collection efforts would not result in a reasonable likelihood of receipt. The allowance for doubtful accounts balance increased $0.4 As of December 31, 2020 December 31, 2019 (in thousands) Trade accounts receivable $ 17,308 $ 13,913 Allowance for doubtful accounts (418 ) (20 ) Total trade accounts receivable, net $ 16,890 $ 13,893 Unbilled receivables Generally, the Company will not bill customers until the services have been completed. From time -to-time -end -end -end Property and equipment Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight -line Software development costs The Company capitalizes costs incurred during the application development and implementation stages for computer software developed or obtained for internal use that are specifically identifiable, have determinable lives and relate to probable future economic benefits. Capitalized computer software costs are included in property and equipment, net in the consolidated balance sheets. Average useful life of such costs is two years. During the years ended December data conversion, and maintenance are expensed as incurred. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Internally developed software did not have any impairment for the years ended December Business Combinations The Company accounts for business combinations under the acquisition method of accounting, in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, recording any assets acquired and liabilities assumed based on their respective fair values. Any excess of the fair value of purchase consideration over the fair value of the assets acquired less liabilities assumed is recorded as goodwill. The Company uses management estimates and industry data to assist in establishing the acquisition date fair values of assets acquired, liabilities assumed, and contingent consideration granted, if any. These estimates and valuations require the Company to make significant assumptions, including projections of future events and operating performance. Goodwill Goodwill represents the excess of purchase price over the fair value of the net assets of businesses acquired. On an annual basis, the Company makes a qualitative assessment to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If the Company determines that the fair value of the reporting unit is less than its carrying amount, it will perform a quantitative analysis; otherwise, no further evaluation is necessary. For the quantitative impairment assessment, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. The Company uses the discounted cash flow method of the income approach and market approach to determine the fair value of the reporting unit. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further testing is performed. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company will recognize a loss equal to the excess, limited to the total amount of goodwill allocated to that reporting unit. Impairments, if any, are charged directly to earnings. As of December Intangible assets Finite -lived -line Fair value Financial instruments are required to be categorized within a valuation hierarchy based upon the lowest level of input that is significant to the fair value measurement. Assets and liabilities recorded at fair value are measured and classified in accordance with a three -tier • Level 1 • Level 2 -based • Level 3 -based Concentrations of credit risk and significant customers Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and accounts receivable. The Company’s cash is held with high -quality The Company records its accounts receivable and unbilled receivables at their face amounts less allowances. Accounts receivable and unbilled receivables are generally dispersed across the Company’s customers in proportion to their revenue. Three customers individually exceeded 10% of the Company’s accounts receivable balance at December The Company has not experienced any losses on its cash and cash equivalents and minimal losses on its accounts receivable. The Company performs ongoing evaluations of its customers’ financial condition. Two, three and three customers accounted for greater than 10% of revenue for the twelve months ended December Foreign currency risks The functional currency of the Company and its subsidiaries is the U.S. dollar with an exception of Daxx, recently acquired by the Company, whose functional currency is the Euro. The Company generates most of its revenues in U.S. dollars. The international subsidiaries convert the U.S. dollars to their respective local currencies to fund operations such as labor and materials required for the entity to operate. The Company’s international subsidiaries’ accounting records are denominated in their respective local currencies. The Company is exposed to foreign currency exchange rate changes that could impact remeasurement of foreign denominated monetary assets and liabilities into U.S. dollars with the remeasurement impact recorded to income. The Company is also exposed to fluctuations in foreign currency exchange rates related to cash outflows for expenditures in foreign currencies. The net income/(loss) on foreign currency transactions was $0.3 the years ended December Revenue recognition The Company accounts for a contract with a customer when 1) the parties to the contract have approved the contract and are committed to performing their respective obligations, 2) the contract identifies each party’s rights regarding the goods or services to be transferred, 3) the contract identifies the payment terms for the goods or services to be transferred, 4) the contract has commercial substance, and 5) collection of substantially all consideration pursuant to the contract is probable. The Company derives its revenue from offering a suite of digital engineering and information technology (“IT”) consulting services, including digital transformation strategy, emerging technology, lean labs and legacy system replatforming. For most contracts, the Company uses master agreements to govern the overall relevant terms and conditions of the business arrangement between the Company and its customers. When the Company and a customer enter into a Master Services Agreement (“MSA”), purchases are generally made by the customer via a statement of work (“SOW”) which explicitly references the MSA and specifies the services to be delivered. Fees for these contracts may be in the form of time -and-materials -fee -and-material Consulting services revenue is a single performance obligation earned through a series of distinct daily services and may include services such as those described above. The Company recognizes revenue for services over time as the customer simultaneously receives and consumes the benefits as the Company performs IT consulting services. For revenue contracts, the customer derives value from the Company providing daily consulting services, and the value derived corresponds to the labor hours expended. Therefore, the Company measures the progress and recognizes revenue using an effort -based For time -and-material available to the Company, taking into consideration the type of customer, the type of transaction and the specific facts and circumstances of each arrangement. Although the Company believes that its approach in developing estimates and its reliance on certain judgments and underlying inputs is reasonable, actual results may differ from management’s estimates, judgments and assumptions. These estimates have historically not been material to the consolidated financial statements. Disaggregation of Total Revenues: The following table shows the disaggregation of the Company’s revenues by contract type for the year ended December Contract Type, in thousands Time-and-material $ 104,583 Fixed-fee 5,705 Other 995 Total Revenues $ 111,283 Remaining performance obligation ASC 606 requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied as of December 1) contracts with an original duration of one year or less, including contracts that can be terminated for convenience without a substantive penalty, 2) contracts for which the Company recognizes revenues based on the right to invoice for services performed, 3) variable consideration allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct good or service that forms part of a single performance obligation in accordance with ASC 606 -10-25-14 -10-32-40 4) variable consideration in the form of a sales -based -based All of the Company’s contracts met one or more of these exemptions as of December Cost of revenue Cost of revenue primarily consists of compensation for professional staff generating revenues for the Company. Compensation includes salary, benefits, performance bonuses, retention bonuses, stock compensation expense, and travel expenses. The Company allocates a portion of depreciation and amortization to cost of revenue. Engineering, research and development Engineering, research, and development expenses primarily include compensation for professional staff performing research and development related activities that are not directly attributable to generating revenues for the Company. Research and development activities relate to building and scaling the next generation ecommerce platform solutions for customers. Research and development costs are expensed as incurred. Engineering, research, and development expenses also include depreciation and amortization costs, stock -based Selling and marketing Selling and marketing expenses are those expenses associated with promoting and selling the Company’s services and include such items as sales and marketing personnel salaries, benefits, stock compensation expenses, travel, advertising, depreciation and amortization, retention bonuses, and other promotional activities. General and administrative General and administrative expenses include other operating items such as officers’ and administrative personnel salaries, benefits, stock compensation expenses, legal and audit expenses, public company related expenses, insurance, facility costs, retention bonuses, depreciation and amortization, including amortization of purchased intangibles, and operating lease expenses. Stock-based compensation expense Stock -based -date -based -date -Scholes-Merton -free -based -date -based -line -based -line -line -vesting -date -line -based Income taxes The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred income taxes are recognized for the tax consequences of temporary differences between the financial statement carrying amounts and the tax basis of the assets and liabilities. The determination of the provision for income taxes requires significant judgment, the use of estimates and the interpretation and application of complex tax laws. The provision for income taxes reflects a combination of income earned and taxed in the various U.S. federal and state, international and other jurisdictions. Jurisdictional tax law changes, increases or decreases in permanent differences between book and tax items, accruals or adjustments of accruals for tax contingencies or valuation allowances, and the change in the mix of earnings from these taxing jurisdictions all affect the overall effective tax rate. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. Management considers all available evidence, both positive and negative, in determining whether a valuation allowance is required. Such evidence includes prior earnings history, the scheduled reversal of deferred tax liabilities, projected future taxable income, carryback and carryforward periods of tax attributes, and tax planning strategies that could potentially enhance the likelihood of realization of a deferred tax asset in making this assessment. The weight given to the positive and negative evidence is commensurate with the extent to which the evidence may be objectively verified. The Company evaluates for uncertain tax positions at each balance sheet date. When it is more likely than not that a position will be sustained upon examination by a tax authority that has full knowledge of all relevant information, the Company measures the amount of tax benefit from the position and records the largest amount of tax benefit that is greater than 50% likely of being realized after settlement with a tax authority. The Company’s policy for interest and/or penalties related to underpayments of income taxes is to include interest and penalties in income tax expense. Restructuring The Company initiated a restructuring plan focused on optimizing utilization. For twelve months ended December Earnings per share The Company accounts for earnings per share in accordance with ASC Topic 260, Earnings per Share. Basic earnings per share is computed by dividing net income by the weighted -average -average Recently adopted accounting pronouncements Changes to U.S. GAAP are established by the Financial Accounting Standards Board (the “FASB”), in the form of Accounting Standards Updates (“ASUs”), to the FASB’s ASC. The Company has elected not to opt out of the extended transition period and thus when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. The Company transitioned to ASC Topic 606, Revenue From Contracts with Customers consolidated statements of income and comprehensive income, balance sheets, or cash flows, and prior periods were not impacted as a result of the adoption of the standard. The new standard resulted in insignificant changes to the timing of recognition of revenues for certain volume discounts.

Business Combinations [Abstract]
Business combination	Note 3 — Business combination On March GDI began operations in September 2006 to provide next -generation Business Combinations, equivalent of GDI issuing stock for the net assets of ChaSerg, accompanied by a recapitalization.

Basis of presentation	Basis of presentation The Business Combination was accounted for as a reverse recapitalization in accordance with U.S. GAAP. Although ChaSerg was the legal acquirer, for accounting purposes, GDI was deemed to be the accounting acquirer. GDI was determined to be the accounting acquirer based on evaluation of the following facts and circumstances: • -to-day • • • • -level In conjunction with the Business Combination, outstanding shares of GDI were converted into common stock of the Company, par value $0.0001 per share, shown as a recapitalization, and the net assets of ChaSerg were acquired at historical cost, with no goodwill or other intangible assets recorded. GDI was deemed to be the predecessor of the Company, and the consolidated assets and liabilities and results of operations prior to the Closing (for the years ended December In accordance with guidance applicable to these circumstances, the equity structure has been restated in all comparative periods up to the Closing Date, to reflect the number of shares of the Company’s common stock, $0.0001 par value per share, issued to GDI shareholders in connection with the recapitalization transaction. As such, the shares and corresponding capital amounts and earnings per share related to GDI preferred and common stock prior to the Business Combination have been retroactively restated as shares reflecting the exchange ratio established in the Business Combination.
Principles of consolidation	Principles of consolidation The accompanying consolidated financial statements include the accounts of the Company and all of its subsidiaries that are directly or indirectly owned or controlled. Intercompany transactions and balances have been eliminated upon consolidation.
Use of estimates	Use of estimates The preparation of the consolidated financial statements in accordance with U.S. GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and such differences could be material. Significant estimates include useful lives and recoverability of property and equipment, determination of fair value, useful lives and recoverability of intangible assets and goodwill, allowances for receivables, calculation of accrued liabilities, capitalization of internally developed software, stock -based

Cash and cash equivalents	Cash and cash equivalents The Company considers cash equivalents to be highly liquid investments with original maturities of three months or less. Cash equivalents are stated at cost, which approximates fair value. At times, cash deposits with banks may exceed federally insured limits.
Accounts receivable and allowance for doubtful accounts	Accounts receivable and allowance for doubtful accounts Accounts receivable, less allowance for doubtful accounts, reflect the net realizable value of receivables and approximate fair value. The Company maintains an allowance against accounts receivable for the estimated probable losses on uncollectible accounts. The allowance is based upon historical loss experience, current economic conditions within the industries the Company serves as well as determination of the specific risk related to certain customers. Accounts receivable are charged off against the reserve when, in management’s estimation, further collection efforts would not result in a reasonable likelihood of receipt.

Capitalized computer software costs are included in property and equipment, net in the consolidated balance sheets. Average useful life of such costs is two years. During the years ended December data conversion, and maintenance are expensed as incurred. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Internally developed software did not have any impairment for the years ended December
Business Combinations	Business Combinations The Company accounts for business combinations under the acquisition method of accounting, in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, recording any assets acquired and liabilities assumed based on their respective fair values. Any excess of the fair value of purchase consideration over the fair value of the assets acquired less liabilities assumed is recorded as goodwill. The Company uses management estimates and industry data to assist in establishing the acquisition date fair values of assets acquired, liabilities assumed, and contingent consideration granted, if any. These estimates and valuations require the Company to make significant assumptions, including projections of future events and operating performance.
Goodwill	Goodwill Goodwill represents the excess of purchase price over the fair value of the net assets of businesses acquired. On an annual basis, the Company makes a qualitative assessment to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If the Company determines that the fair value of the reporting unit is less than its carrying amount, it will perform a quantitative analysis; otherwise, no further evaluation is necessary. For the quantitative impairment assessment, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. The Company uses the discounted cash flow method of the income approach and market approach to determine the fair value of the reporting unit. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further testing is performed. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company will recognize a loss equal to the excess, limited to the total amount of goodwill allocated to that reporting unit. Impairments, if any, are charged directly to earnings. As of December

Fair value	Fair value Financial instruments are required to be categorized within a valuation hierarchy based upon the lowest level of input that is significant to the fair value measurement. Assets and liabilities recorded at fair value are measured and classified in accordance with a three -tier • Level 1 • Level 2 -based • Level 3 -based
Concentrations of credit risk and significant customers	Concentrations of credit risk and significant customers Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and accounts receivable. The Company’s cash is held with high -quality The Company records its accounts receivable and unbilled receivables at their face amounts less allowances. Accounts receivable and unbilled receivables are generally dispersed across the Company’s customers in proportion to their revenue. Three customers individually exceeded 10% of the Company’s accounts receivable balance at December The Company has not experienced any losses on its cash and cash equivalents and minimal losses on its accounts receivable. The Company performs ongoing evaluations of its customers’ financial condition. Two, three and three customers accounted for greater than 10% of revenue for the twelve months ended December
Foreign currency risks	Foreign currency risks The functional currency of the Company and its subsidiaries is the U.S. dollar with an exception of Daxx, recently acquired by the Company, whose functional currency is the Euro. The Company generates most of its revenues in U.S. dollars. The international subsidiaries convert the U.S. dollars to their respective local currencies to fund operations such as labor and materials required for the entity to operate. The Company’s international subsidiaries’ accounting records are denominated in their respective local currencies. The Company is exposed to foreign currency exchange rate changes that could impact remeasurement of foreign denominated monetary assets and liabilities into U.S. dollars with the remeasurement impact recorded to income. The Company is also exposed to fluctuations in foreign currency exchange rates related to cash outflows for expenditures in foreign currencies. The net income/(loss) on foreign currency transactions was $0.3 the years ended December
Revenue recognition	Revenue recognition The Company accounts for a contract with a customer when 1) the parties to the contract have approved the contract and are committed to performing their respective obligations, 2) the contract identifies each party’s rights regarding the goods or services to be transferred, 3) the contract identifies the payment terms for the goods or services to be transferred, 4) the contract has commercial substance, and 5) collection of substantially all consideration pursuant to the contract is probable. The Company derives its revenue from offering a suite of digital engineering and information technology (“IT”) consulting services, including digital transformation strategy, emerging technology, lean labs and legacy system replatforming. For most contracts, the Company uses master agreements to govern the overall relevant terms and conditions of the business arrangement between the Company and its customers. When the Company and a customer enter into a Master Services Agreement (“MSA”), purchases are generally made by the customer via a statement of work (“SOW”) which explicitly references the MSA and specifies the services to be delivered. Fees for these contracts may be in the form of time -and-materials -fee -and-material Consulting services revenue is a single performance obligation earned through a series of distinct daily services and may include services such as those described above. The Company recognizes revenue for services over time as the customer simultaneously receives and consumes the benefits as the Company performs IT consulting services. For revenue contracts, the customer derives value from the Company providing daily consulting services, and the value derived corresponds to the labor hours expended. Therefore, the Company measures the progress and recognizes revenue using an effort -based For time -and-material available to the Company, taking into consideration the type of customer, the type of transaction and the specific facts and circumstances of each arrangement. Although the Company believes that its approach in developing estimates and its reliance on certain judgments and underlying inputs is reasonable, actual results may differ from management’s estimates, judgments and assumptions. These estimates have historically not been material to the consolidated financial statements.

Income taxes	Income taxes The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred income taxes are recognized for the tax consequences of temporary differences between the financial statement carrying amounts and the tax basis of the assets and liabilities. The determination of the provision for income taxes requires significant judgment, the use of estimates and the interpretation and application of complex tax laws. The provision for income taxes reflects a combination of income earned and taxed in the various U.S. federal and state, international and other jurisdictions. Jurisdictional tax law changes, increases or decreases in permanent differences between book and tax items, accruals or adjustments of accruals for tax contingencies or valuation allowances, and the change in the mix of earnings from these taxing jurisdictions all affect the overall effective tax rate. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. Management considers all available evidence, both positive and negative, in determining whether a valuation allowance is required. Such evidence includes prior earnings history, the scheduled reversal of deferred tax liabilities, projected future taxable income, carryback and carryforward periods of tax attributes, and tax planning strategies that could potentially enhance the likelihood of realization of a deferred tax asset in making this assessment. The weight given to the positive and negative evidence is commensurate with the extent to which the evidence may be objectively verified. The Company evaluates for uncertain tax positions at each balance sheet date. When it is more likely than not that a position will be sustained upon examination by a tax authority that has full knowledge of all relevant information, the Company measures the amount of tax benefit from the position and records the largest amount of tax benefit that is greater than 50% likely of being realized after settlement with a tax authority. The Company’s policy for interest and/or penalties related to underpayments of income taxes is to include interest and penalties in income tax expense.

Recently adopted accounting pronouncements	Recently adopted accounting pronouncements Changes to U.S. GAAP are established by the Financial Accounting Standards Board (the “FASB”), in the form of Accounting Standards Updates (“ASUs”), to the FASB’s ASC. The Company has elected not to opt out of the extended transition period and thus when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. The Company transitioned to ASC Topic 606, Revenue From Contracts with Customers consolidated statements of income and comprehensive income, balance sheets, or cash flows, and prior periods were not impacted as a result of the adoption of the standard.

CARES Act description	The CARES Act contains several corporate income tax provisions, including making remaining alternative minimum tax credits immediately refundable; providing a 5-year carryback of net operating loss carryforwards (“NOLs”) generated in tax years 2018, 2019, and 2020, and removing the 80% taxable income limitation on utilization of those NOLs if carried back to prior tax years or utilized in tax years beginning before 2021; and temporarily liberalizing the interest deductibility rules under Section 163(j) of the Tax Cuts and Jobs Act, by raising the adjusted taxable income limitation from 30% to 50% for tax years 2019 and 2020 and giving taxpayers the election of using 2019 adjusted taxable income for purposes of computing 2020 interest deductibility.
