Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	Nature of Business and Significant Accounting Policies Nature of business: The Company provides enterprise engineering, telecommunications, information management and security products and services to the federal government and commercial businesses. Segment information is not presented since all of the Company’s revenue is attributed to a single reportable segment. STG Group was incorporated in the State of Delaware on July 12, 2012, for the purpose of holding shares of STG, Inc. (STG) and the ownership interests of other entities in the future. Concurrent with the incorporation of STG Group, STG became a wholly-owned subsidiary of STG Group. Effective July 27, 2012, STG Ventures, LLC (STG Ventures) was created and its sole member was STG Group. On October 24, 2012, STG Netherlands, B.V. (STG Netherlands) was created as a cooperative in Amsterdam, and is 99% owned by STG Group and 1% owned by STG Ventures. Effective November 28, 2012, STG Doha, LLC (STG Doha) was incorporated in Doha, Qatar, and is 49% owned by STG Netherlands and 51% owned by Pro-Partnership, a local Qatar Company. STG Group holds full control over STG Doha due to an arrangement with the other partner, whereby the partner gives up ownership rights in lieu of a management fee paid to them by STG Group. STG Ventures, STG Netherlands and STG Doha did not have significant activity from the dates of inception through the year ended December 31, 2016, periods from November 24, 2015 through December 31, 2015 and January 1, 2015 through November 23, 2015, and year ended December 31, 2014, since any activity would be eliminated entirely upon consolidation with STG Group or with the Company. At the close of business on December 31, 2012, STG Group entered into a Reorganization and Acquisition Agreement with the stockholders of Access Systems, Incorporated (Access), a company incorporated under the laws of the Commonwealth of Virginia on June 15, 1992, to acquire all of the outstanding common stock of Access. Access provides software development and facilities management under contractual relationships, primarily with various agencies of the federal government. On January 2, 2013, STG Group contributed all of the outstanding common stock of Access to STG, Inc. As a result of the transfer, Access became STG, Inc.’s wholly owned subsidiary. During the year ended December 31, 2013, STG Group formed STG Sentinel, LLC (Sentinel). During the year ended December 31, 2014, Sentinel formed STG Sentinel AFG, LLC (Sentinel AFG). STG Group is the sole member of Sentinel, which is the sole member of Sentinel AFG. There was no significant activity related to any of these subsidiaries formed during the year ended December 31, 2016, periods from November 24, 2015 through December 31, 2015 and January 1, 2015 through November 23, 2015, and year ended December 31, 2014. A summary of the Company’s significant accounting policies follows: Basis of presentation and principles of consolidation: The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The consolidated financial statements include the accounts of STG Group, Inc. (Successor) and STG Group (Predecessor) and their wholly owned subsidiaries, including STG Doha, which is consolidated under the variable interest entity model. Activity under STG Doha is immaterial to these consolidated financial statements. These entities are collectively referred to as the Company. All intercompany accounts and transactions have been eliminated in the accompanying consolidated financial statements. Figures are expressed in thousands of dollars unless otherwise indicated. Going Concern Consideration: The Company was not in compliance with its financial covenants at September 30, 2016 or at December 31, 2016. At September 30, 2016, the non-compliance was cured by raising equity from stockholders’ (“Equity Cure”) as was allowed by the Lending Agreement. At December 31, 2016 the Company received a forbearance which expired on March 31, 2017. The Company entered into a Limited Waiver (“the Waiver”) from MC Admin Co LLC and other lenders under the Credit Agreement as of March 31, 2017, pursuant to which the lenders waived the Company’s non-compliance with the Specified Financial Covenants as of December 31, 2016. Based upon the preliminary results of operations through the first quarter of 2017, the Company anticipates that it will not be in compliance with the same financial covenants at March 31, 2017. One of the remedies the Lender has available to it, amongst others is the ability to accelerate repayment of the loan which the Company would not be able to immediately repay. The potential inability to meet financial covenants under the Company’s existing Credit Agreement and the potential acceleration of the debt by the Lender resulting in the reclassification of our debt from a long-term liability to a current liability due to the potential of future covenant defaults required us to evaluate whether there is substantial doubt regarding the Company’s ability to continue as a going concern. Management’s Plan to alleviate this condition is as follows: 1. Identify, qualify, and win new business to increase revenue and profits. 2. Complete the PSS transaction including the raising of equity and refinancing of our current Credit Agreement; or 3. Renegotiate the current Credit Agreement to obtain relief from the existing financial covenants and other terms. We considered the likelihood of refinancing the current Credit Agreement in connection with the PSS acquisition financing which contemplates new financial covenants and the renegotiation of the financial covenants in the event the acquisition of PSS is not completed. Based upon the executed term sheet for financing of the planned acquisition of the PSS which contemplates new financial covenants and discussions with our Lender regarding the need to renegotiate the existing financial covenants in the Credit Agreement in the event the acquisition is not completed, management determined that it was probable that the condition giving rise to the going concern evaluation has been sufficiently alleviated. These consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets and liabilities that may result in the Company not being able to continue as a going concern. Use of estimates: Significant estimates embedded in the consolidated financial statements for the periods presented include revenue recognition on fixed-price contracts, the allowance for doubtful accounts, the valuation and useful lives of intangible assets, the length of certain customer relationships, useful lives of property, plant and equipment, valuation of a Rabbi Trust and related deferred compensation liability. Estimates and assumptions are also used when determining the allocation of the purchase price in a business combination to the fair value of assets and liabilities and determining related useful lives. Revenue recognition: Revenue on cost-plus-fee contracts is recognized to the extent of costs incurred plus a proportionate amount of the fee earned. The Company considers fixed fees under cost-plus-fee contracts to be earned in proportion to the allowable costs incurred in performance of the contract. The Company considers performance-based fees, including award fees, under any contract type to be earned when it can demonstrate satisfaction of performance goals, based upon historical experience, or when the Company receives contractual notification from the customer that the fee has been earned. Revenue on time-and-materials contracts is recognized based on the hours incurred at the negotiated contract billing rates, plus the cost of any allowable material costs and out-of-pocket expenses. Revenue on fixed-price contracts is primarily recognized using the proportional performance method of contract accounting. Unless it is determined as part of the Company’s regular contract performance review that overall progress on a contract is not consistent with costs expended to date, the Company determines the percentage completed based on the percentage of costs incurred to date in relation to total estimated costs expected upon completion of the contract. Revenue on other fixed-price service contracts is generally recognized on a straight-line basis over the contractual service period, unless the revenue is earned, or obligations fulfilled, in a different manner. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined and are recorded as forward loss liabilities in the consolidated financial statements. Changes in job performance, job conditions and estimated profitability may result in revisions to costs and revenue and are recognized in the period in which the revisions are determined. Multiple agencies of the federal government directly or indirectly provided the majority of the Company’s contract revenue during the year ended December 31, 2016 and periods from November 24, 2015 through December 31, 2015 and from January 1, 2015 through November 23, 2015, and the year ended December 31, 2014. For the year ended December 31, 2016 and periods from November 24, 2015 through December 31, 2015 and from January 1, 2015 through November 23, 2015, and the year ended December 31, 2014, there were two, three, two, and three customers, respectively, that each provided revenue in excess of 10% of total revenue. These customers accounted for approximately 78%, 89%, 75%, and 84%, respectively, of the Company’s total revenue for the year ended December 31, 2016, periods from November 24, 2015 through December 31, 2015 and from January 1, 2015 through November 23, 2015, and the year ended December 31, 2014. Federal government contract costs, including indirect costs, are subject to audit and adjustment by the Defense Contract Audit Agency. Contract revenue has been recorded in amounts that are expected to be realized upon final settlement. Costs of revenue: For the year ended December 31, 2016, periods from November 24, 2015 through December 31, 2015 and from January 1, 2015 through November 23, 2015, and the year ended December 31, 2014, there was one vendor that comprised approximately 16%, 10%, 11%, and 10%, of total direct expenses, respectively. Cash and cash equivalents: Investments held in Rabbi Trust: Contract receivables: Unbilled amounts represent costs and anticipated profits awaiting milestones to bill, contract retainages, award fees and fee withholdings, as well as amounts currently billable. In accordance with industry practice, contract receivables relating to long-term contracts are classified as current, even though portions of these amounts may not be realized within one year. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. Management has recorded an allowance for contract receivables that are considered to be uncollectible. Both billed and unbilled receivables are written off when deemed uncollectible. Recoveries of receivables previously written off are recorded when received. Valuation of long-lived assets: Identifiable intangible assets: Goodwill: Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units and determination of the fair value of each reporting unit. The fair value of each reporting unit is estimated using a discounted cash flow methodology. This analysis requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for the business, estimation of the useful life over which cash flows will occur and determination of the weighted-average cost of capital. This discounted cash flow analysis is corroborated by top-down analysis, including a market assessment of enterprise value. The Company has elected to perform its annual analysis on December 31 each year at the reporting unit level and, during the Predecessor periods, had identified three reporting units with goodwill: DSTI, Seamast, and Access Systems. During the period from January 1, 2015 through November 23, 2015 and the year ended December 31, 2014, the Company recorded an impairment loss for goodwill of $2.1 million and $5.1 million, respectively. As of the Closing Date of the Business Combination, the Company determined that there was one reporting unit and as a result of acquisition accounting for the Business Combination, the carrying value of the reporting unit was equal to its fair value on the Closing Date. After performing a step zero analysis, no indicators of impairment were identified for the period from November 24, 2015 through December 31, 2015. For the year ended December 31, 2016, the Company has been unable to achieve its targeted revenue and profit forecasts; therefore, the Company recorded an impairment loss for goodwill of $41.3 million. Income taxes: The Company accounts for income taxes under FASB Accounting Standards Codification (ASC) Topic 740, Income Taxes (ASC 740). At the end of each interim period, the Company estimates an annualized effective tax rate expected for the full year based on the most recent forecast of pre-tax income, permanent book and tax differences, and global tax planning strategies. The Company uses this effective rate to provide for income taxes on a year-to-date basis, excluding the effect of significant In accordance with authoritative guidance on accounting for uncertainty in income taxes issued by the FASB, management has evaluated the Company’s tax positions and has concluded that the Company has taken no uncertain tax positions that require adjustment to the quarterly condensed consolidated financial statements to comply with the provisions of this guidance. Interest and penalties related to tax matters are recognized in expense. There was no accrued interest or penalties recorded during the year ended December 31, 2016, for the periods from November 24, 2015 through December 31, 2015 and from January 1, 2015 through November 23, 2015, and the year ended December 31, 2014. STG Group (Predecessor) is generally no longer subject to income tax examinations by the U.S. federal, state or local tax authorities for the years ended December 31, 2013, and prior. Fair value of financial instruments Certain assets and liabilities are recorded at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability between market participants in an orderly transaction on the measurement date. The market in which the reporting entity would sell the asset or transfer the liability with the greatest volume and level of activity for the asset or liability is known as the principal market. When no principal market exists, the most advantageous market is used. This is the market in which the reporting entity would sell the asset or transfer the liability with the price that maximizes the amount that would be received or minimizes the amount that would be paid. Fair value is based on assumptions market participants would make in pricing the asset or liability. Generally, fair value is based on observable quoted market prices or derived from observable market data when such market prices or data are available. When such prices or inputs are not available, the reporting entity should use valuation models. The Company’s assets recorded at fair value on a recurring basis are categorized based on the priority of the inputs used to measure fair value. Fair value measurement standards require an entity to maximize the use of observable inputs (such as quoted prices in active markets) and minimize the use of unobservable inputs (such as appraisals or other valuation techniques) to determine fair value. The inputs used in measuring fair value are categorized into three levels, as follows: Level 1: Inputs that are based upon quoted prices for identical instruments traded in active markets. Level 2: Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar investments in markets that are not active, or models based on valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the investment. Level 3: Inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models and similar techniques. As of December 31, 2016 and 2015, the Company has no financial assets or liabilities that are categorized as Level 3. The Company has investments carried at fair value in mutual funds held in a Rabbi Trust, which is included in investments held in Rabbi Trust on the accompanying consolidated balance sheets. The Company does not measure non-financial assets and liabilities at fair value unless there is an event which requires this measurement. Financial credit risk: Debt issuance costs: Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs Transaction-related expenses: The Company incurs transaction-related expenses primarily consisting of professional service fees and costs related to business acquisition activities. The Company recognized transaction-related expenses of approximately $2.6 million, $0.6 million, and $0.89 million, respectively, during the year ended December 31, 2016, the period from November 24, 2015 through December 31, 2015, and the period from January 1, 2015 through November 23, 2015, which primarily includes fees related to the Business Combination and related transactions, and the pending transaction disclosed further in Note 15. The transaction-related expenses were recognized as incurred within the respective Successor or Predecessor periods in accordance with the applicable accounting guidance on business combinations and classified with indirect and selling expenses on the consolidated statements of operations.

ASU 2017-04 provides guidance to simplify the subsequent measurement of goodwill by eliminating the Step 2 procedure from the goodwill impairment test. Under the updates in ASU 2017-04, an entity should perform its annual or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments of this ASU are effective for annual or any interim goodwill impairment tests beginning after December 15, 2019. The Company has not yet evaluated the impact, if any, that the adoption of ASU 2017-04 will have on our Consolidated Financial Statements.

Subsequent to the Business Combination, the Company determined that there was one reporting unit and determined that the carrying value of the reporting unit was equal to its fair value on the Closing Date. For the year ended December 31, 2016, the Company recorded an impairment loss of $ 41.3 In performing the second step of the impairment testing, the Company’s third party valuation firm performed a theoretical purchase price allocation for the Company to determine the implied fair values of goodwill which were compared to the recorded amounts of goodwill for the Company’s sole reporting unit. Upon completion of the second step of the goodwill impairment test, the Company recorded a noncash goodwill impairment charge of $ 41.3 36 5 8 11 14 The goodwill impairment charges are recorded as impairment charges in the consolidated statements of operations. The assumptions that have the most significant impact on determination of the reporting unit fair value are the revenue growth rate, including 3 percent in the terminal year, maintaining adjusted EBITDA margins of 10 15.08 For the period from January 1, 2015 through November 23, 2015, the Company recorded an impairment loss on Access Systems’ goodwill of $ 2.0 3.5 1.7 0.91 1.8 The primary methods used to measure the impairment losses were the income method and the market approach. The significant unobservable inputs used were based on Company-specific information and included estimates of revenue, profit margins and discount rates. The Company used the two-step approach in measuring the impairment loss. In the second step, the implied value of the goodwill is estimated at the fair value of the reporting unit less the fair value of all other tangible and identifiable intangible assets of the reporting unit. If the carrying amount of the goodwill exceeds the implied fair value of the goodwill, an impairment loss is recognized in the amount equal to that excess, not to exceed the carrying amount of the goodwill. Following an assessment of revenue, profit, and cash flow projections and the relevant discount rates, the Company did not record any impairment charges for the Successor period during the period from November 24, 2015 through December 31, 2015. Additionally, the Company performed an impairment test on its long-lived intangible assets. The first step of the impairment test is to compare the undiscounted cash flows of the asset group to the carrying amount. If the results of the test determine that the undiscounted cash flows of the asset group are less than the carrying amount, then an impairment exists and further testing is required. An impairment was not required as of December 31, 2016.

The Company replaced the prior credit facility and entered into a new facility (the Credit Agreement) with a different lending Group. The Credit Agreement provides for (a) a term loan in an aggregate principal amount of $ 81.8 15 90 November 23, 2020 6.4 The principal amount of the term loan amortizes in quarterly installments which increase after each annual period. The quarterly installments range from 0.625 2.500 At the Company’s election, the interest rate per annum applicable to all the facilities is based on a fluctuating rate of interest. The interest rate in effect as of December 31, 2016 and 2015 was 10.30 8.80 The Wall Street Journal The interest rate per annum for electing the Eurodollar Rate will be equal to the sum of 7.80% plus the Eurodollar Rate Advances under the revolving line-of-credit are limited by a borrowing base which may not exceed the lesser of (x) the difference between $15 million and amounts outstanding under letters of credit issued pursuant to the Credit Agreement; and (y) an amount equal to the sum of: (i) up to 85% of certain accounts receivable of the Company plus (ii) up to 100% of unrestricted cash on deposit in the Company’s accounts with the Collateral Agent, minus (iii) amounts outstanding under letters of credit issued pursuant to the Credit Agreement, minus (iv) reserves established by the Collateral Agent from time to time in its reasonable credit judgment exercised in good faith. The amount available under the line-of-credit was $15 million at December 31, 2016 (subject to lender consent) and 2015. The Company is also subject to certain provisions which will require mandatory prepayments of its term loan and has agreed to certain minimums for its fixed charge coverage ratio and consolidated EBITDA and certain maximums for its senior secured leverage ratio, as defined in the Credit Agreement. As of September 30, 2016, the Company did not meet the required consolidated senior secured leverage ratio and minimum consolidated EBITDA. The Company remained in compliance with the Credit Agreement as of September 30, 2016 by using a provision of the Credit Agreement that allowed the Company to cure (the "Cure Right") certain covenant non-compliance by issuances of common stock for cash and use of the proceeds to reduce the principal balance of the term loan. On November 14, 2016, the Company entered into Common Stock Purchase Agreements with Simon S. Lee Management Trust, for which Simon Lee, Chairman, is Trustee, and Phillip E. Lacombe, President and Chief Operating Officer (collectively, the “Investors”), that provided for the sale to the Investors of 462,778 3.60 1.7 As of December 31, 2016, the Company did not satisfy the covenants related to its required consolidated senior secured leverage ratio and minimum consolidated EBITDA. The Credit Agreement does not allow the Company to exercise the Cure Right in consecutive fiscal quarters; therefore, on February 24, 2017, the Company entered into a limited forbearance to credit agreement (the “Forbearance Agreement”) with MC Admin Co LLC and the other lenders under the Credit Agreement. In the Forbearance Agreement, the lenders agreed to forbear from exercising rights and remedies (including enforcement and collection actions), for which we agreed to pay a fee of up to $ 750,000 2 The Company entered into a Limited Waiver (“the Waiver”) from MC Admin Co LLC and other lenders under the Credit Agreement as of March 31, 2017, · Loans under the Credit Agreement are subject to additional interest at a rate of 2 until the earliest of (x) the date on which all loans are repaid and all commitments under the Credit Agreement are terminated, (y) the date we deliver the financial statements and certificates for the quarter ending March 31, 2017 showing that we are not in default under the Credit Agreement or (z) the date on which default interest is otherwise due under the Credit Agreement; · We must obtain lender consent prior to use of our revolving credit facility; and · We cannot effect a Cure Right in respect of the quarter ending March 31, 2017. The Credit Agreement also provides that the minimum consolidated EBITDA requirement will be increased on June 30, 2017. If our business continues to perform at the current level through that period, we do not expect to satisfy that covenant or the senior secured leverage ratio at that time, and it is likely that we will be in non-compliance at March 31, 2017. An inability to meet the required covenant levels could have a material adverse impact on us, including the need for us to effect an additional Cure Right or obtain additional forbearance or an amendment, waiver, or other changes in the Credit Agreement. The Credit Agreement does not allow the Company to exercise the Cure Right in consecutive fiscal quarters, more than three fiscal quarters in the aggregate, in more than two of any four fiscal quarters or for the quarter ending March 31, 2017. The amount allowed under the Cure Right may not exceed the lesser of $ 2.5 20 5 If we are not able to effect an amendment to the Credit Agreement, any future covenant non-compliance will give rise to an event of default thereunder if we are unable to effect a Cure Right or otherwise obtain forbearance or a waiver in which case the indebtedness under the Credit Agreement could be declared immediately due and payable, which could have a material adverse effect on the Company.

Management Incentive Plan (the MIP Plan) in place prior to the consummation of the Business Combination. The MIP Plan was created effective November 1, 2011. The purpose of the MIP Plan was to enable STG Group to retain and recruit employees by providing them with the incentive of participating in the appreciation of the value of the STG Group’s common stock. The value of STG Group’s common stock represented the equity value determined by the Plan Committee based on a valuation performed by an external appraisal, which was performed as of the effective date of the MIP Plan (baseline valuation). The appreciation in value of the common stock, if any, was determined based on the appreciation between the baseline valuation and an internal appraisal performed by STG Group or external appraisal annually. STG Group would record annual compensation expense based on the proportion of this appreciation allocated to designated individuals. Only designated individuals had been identified to participate in the MIP Plan, as determined by the MIP Plan Committee. Awards (units under the MIP Plan) could be granted by the MIP Plan Committee at any time. Participants vested daily in their awards over a three year measurement period. If a participant remained employed with STG Group through the fifth anniversary of the grant date of an award, the participant’s plan account would be paid in three annual installments, commencing immediately following the fifth anniversary. If an employee separated from STG Group for other than cause, the participant’s vested portion would be paid in three annual installments, the first of which being due on the anniversary date of the first year of separation. If a change of control event were to occur (change in over 50% ownership), then all vested amounts under the grant were to be payable within five business days of such change of control. Select individuals were designated to participate in the MIP Plan. Upon consummation of the Business Combination, the MIP Plan was terminated with no resulting payouts to the participants.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Nature of business: STG Group, Inc. (formerly, Global Defense & National Security Systems, Inc. or GDEF) and its subsidiaries (collectively, the Company) was originally incorporated in Delaware on July 3, 2013 as a blank check company, with Global Defense & National Security Holdings LLC (“Global Defense LLC” or the “Sponsor”) as Sponsor, formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, exchangeable share transaction or other similar business combination. On November 23, 2015, the Company consummated its business combination with STG Group Holdings, Inc. (formerly, STG Group, Inc. or “STG Group”) pursuant to the stock purchase agreement, dated as of June 8, 2015, which provided for the purchase of all the capital stock of STG Group by the Company (the “Business Combination”). In connection with the closing of the Business Combination, the Company ceased to be a shell company in accordance with its Amended and Restated Certificate of Incorporation. The Company also changed its name from Global Defense & National Security Systems, Inc. to STG Group, Inc., and the Company’s securities were delisted from The NASDAQ Capital Market. The Company recommenced trading of its common stock under the symbol “STGG” on the OTC Pink Current Information tier of the over-the-counter market. The Company’s common stock now trades over-the-counter on the OTCQB. See Note 2 for a further discussion of the Business Combination. The Company provides enterprise engineering, telecommunications, information management and security products and services to the federal government and commercial businesses. Segment information is not presented since all of the Company’s revenue is attributed to a single reportable segment. STG Group was incorporated in the State of Delaware on July 12, 2012, for the purpose of holding shares of STG, Inc. (STG) and the ownership interests of other entities in the future. Concurrent with the incorporation of STG Group, STG became a wholly-owned subsidiary of STG Group. Effective July 27, 2012, STG Ventures, LLC (STG Ventures) was created and its sole member was STG Group. On October 24, 2012, STG Netherlands, B.V. (STG Netherlands) was created as a cooperative in Amsterdam, and is 99 1 49 51 STG Ventures, STG Netherlands and STG Doha did not have significant activity from the dates of inception through the year ended December 31, 2016, periods from November 24, 2015 through December 31, 2015 and January 1, 2015 through November 23, 2015, and year ended December 31, 2014, since any activity would be eliminated entirely upon consolidation with STG Group or with the Company. At the close of business on December 31, 2012, STG Group entered into a Reorganization and Acquisition Agreement with the stockholders of Access Systems, Incorporated (Access), a company incorporated under the laws of the Commonwealth of Virginia on June 15, 1992, to acquire all of the outstanding common stock of Access. Access provides software development and facilities management under contractual relationships, primarily with various agencies of the federal government. On January 2, 2013, STG Group contributed all of the outstanding common stock of Access to STG, Inc. As a result of the transfer, Access became STG, Inc.’s wholly owned subsidiary. During the year ended December 31, 2013, STG Group formed STG Sentinel, LLC (Sentinel). During the year ended December 31, 2014, Sentinel formed STG Sentinel AFG, LLC (Sentinel AFG). STG Group is the sole member of Sentinel, which is the sole member of Sentinel AFG. There was no significant activity related to any of these subsidiaries formed during the year ended December 31, 2016, periods from November 24, 2015 through December 31, 2015 and January 1, 2015 through November 23, 2015, and year ended December 31, 2014. A summary of the Company’s significant accounting policies follows:
Consolidation, Policy [Policy Text Block]	Basis of presentation and principles of consolidation: As a result of the Business Combination, the Company was identified as the acquirer for accounting purposes, and STG Group is the acquiree and accounting predecessor. This determination was based upon an evaluation of facts which included, but was not limited to, consideration of the following: 1) the relative voting rights of the stockholders in the combined entity after the Business Combination; 2) the composition of the board of directors of the combined entity; 3) the composition of the senior management team of the combined entity; 4) and the cash consideration that was transferred by the Company to the acquiree’s shareholders. Based upon this evaluation, the preponderance of facts supported the conclusion that the Company was the accounting acquirer. The Company’s consolidated financial statement presentation distinguishes a “Predecessor” for STG Group for the periods up to and prior to the Closing Date. The Company was subsequently re-named as STG Group, Inc. and is the “Successor” for periods after the Closing Date, which includes the consolidation of STG Group subsequent to the Business Combination. The acquisition was accounted for as a business combination using the acquisition method of accounting, and Successor financial statements reflect a new basis of accounting that is based on the fair value of the net assets acquired. See Note 2 for further discussion of the Business Combination. As a result of the application of the acquisition method of accounting as of the effective date of the acquisition, the financial statements for the Predecessor period and for the Successor period are presented on a different basis and, therefore, are not comparable. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The consolidated financial statements include the accounts of STG Group, Inc. (Successor) and STG Group (Predecessor) and their wholly owned subsidiaries, including STG Doha, which is consolidated under the variable interest entity model. Activity under STG Doha is immaterial to these consolidated financial statements. These entities are collectively referred to as the Company. All intercompany accounts and transactions have been eliminated in the accompanying consolidated financial statements. Figures are expressed in thousands of dollars unless otherwise indicated.
Going Concern [Policy Text Block]	Going Concern Consideration: The Company was not in compliance with its financial covenants at September 30, 2016 or at December 31, 2016. At September 30, 2016, the non-compliance was cured by raising equity from stockholders’ (“Equity Cure”) as was allowed by the Lending Agreement. At December 31, 2016 the Company received a forbearance which expired on March 31, 2017. The Company entered into a Limited Waiver (“the Waiver”) from MC Admin Co LLC and other lenders under the Credit Agreement as of March 31, 2017, pursuant to which the lenders waived the Company’s non-compliance with the Specified Financial Covenants as of December 31, 2016. Based upon the preliminary results of operations through the first quarter of 2017, the Company anticipates that it will not be in compliance with the same financial covenants at March 31, 2017. One of the remedies the Lender has available to it, amongst others is the ability to accelerate repayment of the loan which the Company would not be able to immediately repay. The potential inability to meet financial covenants under the Company’s existing Credit Agreement and the potential acceleration of the debt by the Lender resulting in the reclassification of our debt from a long-term liability to a current liability due to the potential of future covenant defaults required us to evaluate whether there is substantial doubt regarding the Company’s ability to continue as a going concern. Management’s Plan to alleviate this condition is as follows: 1. Identify, qualify, and win new business to increase revenue and profits. 2. Complete the PSS transaction including the raising of equity and refinancing of our current Credit Agreement; or 3. Renegotiate the current Credit Agreement to obtain relief from the existing financial covenants and other terms. We considered the likelihood of refinancing the current Credit Agreement in connection with the PSS acquisition financing which contemplates new financial covenants and the renegotiation of the financial covenants in the event the acquisition of PSS is not completed. Based upon the executed term sheet for financing of the planned acquisition of the PSS which contemplates new financial covenants and discussions with our Lender regarding the need to renegotiate the existing financial covenants in the Credit Agreement in the event the acquisition is not completed, management determined that it was probable that the condition giving rise to the going concern evaluation has been sufficiently alleviated. These consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets and liabilities that may result in the Company not being able to continue as a going concern.
Use of Estimates, Policy [Policy Text Block]	Use of estimates: The preparation of financial statements 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 consolidated financial statements. Actual results could differ from those estimates. Significant estimates embedded in the consolidated financial statements for the periods presented include revenue recognition on fixed-price contracts, the allowance for doubtful accounts, the valuation and useful lives of intangible assets, the length of certain customer relationships, useful lives of property, plant and equipment, valuation of a Rabbi Trust and related deferred compensation liability. Estimates and assumptions are also used when determining the allocation of the purchase price in a business combination to the fair value of assets and liabilities and determining related useful lives.
Revenue Recognition, Loyalty Programs [Policy Text Block]	Revenue recognition: Revenue is recognized when persuasive evidence of an arrangement exists, services have been rendered or goods delivered, the contract price is fixed or determinable and collectability is reasonably assured. Revenue associated with work performed prior to the completion and signing of contract documents is recognized only when it can be reliably estimated and realization is probable. The Company bases its estimates on previous experiences with the customer, communications with the customer regarding funding status and its knowledge of available funding for the contract. Revenue on cost-plus-fee contracts is recognized to the extent of costs incurred plus a proportionate amount of the fee earned. The Company considers fixed fees under cost-plus-fee contracts to be earned in proportion to the allowable costs incurred in performance of the contract. The Company considers performance-based fees, including award fees, under any contract type to be earned when it can demonstrate satisfaction of performance goals, based upon historical experience, or when the Company receives contractual notification from the customer that the fee has been earned. Revenue on time-and-materials contracts is recognized based on the hours incurred at the negotiated contract billing rates, plus the cost of any allowable material costs and out-of-pocket expenses. Revenue on fixed-price contracts is primarily recognized using the proportional performance method of contract accounting. Unless it is determined as part of the Company’s regular contract performance review that overall progress on a contract is not consistent with costs expended to date, the Company determines the percentage completed based on the percentage of costs incurred to date in relation to total estimated costs expected upon completion of the contract. Revenue on other fixed-price service contracts is generally recognized on a straight-line basis over the contractual service period, unless the revenue is earned, or obligations fulfilled, in a different manner. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined and are recorded as forward loss liabilities in the consolidated financial statements. Changes in job performance, job conditions and estimated profitability may result in revisions to costs and revenue and are recognized in the period in which the revisions are determined. Multiple agencies of the federal government directly or indirectly provided the majority of the Company’s contract revenue during the year ended December 31, 2016 and periods from November 24, 2015 through December 31, 2015 and from January 1, 2015 through November 23, 2015, and the year ended December 31, 2014. For the year ended December 31, 2016 and periods from November 24, 2015 through December 31, 2015 and from January 1, 2015 through November 23, 2015, and the year ended December 31, 2014, there were two three two three 10 78 89 75 84 Federal government contract costs, including indirect costs, are subject to audit and adjustment by the Defense Contract Audit Agency. Contract revenue has been recorded in amounts that are expected to be realized upon final settlement.
Cost of Sales, Policy [Policy Text Block]	Costs of revenue include all direct contract costs, as well as indirect overhead costs and selling, general and administrative expenses that are allowable and allocable to contracts under federal procurement standards. Costs of revenue also include costs and expenses that are unallowable under applicable procurement standards and are not allocable to contracts for billing purposes. Such costs and expenses do not directly generate revenue, but are necessary for business operations. For the year ended December 31, 2016, periods from November 24, 2015 through December 31, 2015 and from January 1, 2015 through November 23, 2015, and the year ended December 31, 2014, there was one vendor 16 10 11 10
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and cash equivalents: The Company considers all highly liquid investments purchased with an original maturity of three months or less at the date of purchase to be cash equivalents.
Investments Held In Rabbi Trust [Policy Text Block]	The Company has investments in mutual funds held in a Rabbi Trust that are classified as trading securities. Management determines the appropriate classification of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date. The securities are classified as trading securities because they are held for resale in anticipation of short-term (generally 90 days or less) fluctuations in market prices. The trading securities are stated at fair value. Realized and unrealized gains and losses and other investment income are included in other income (expense) in the accompanying consolidated statements of operations.
Receivables, Policy [Policy Text Block]	Contract receivables: Contract receivables are generated primarily from prime and subcontracting arrangements with federal governmental agencies. Billed contract receivables represent invoices that have been prepared based on contract terms and sent to the customer. Billed accounts receivable are considered past due if the invoice has been outstanding more than 30 days. The Company does not charge interest on accounts receivable; however, federal governmental agencies may pay interest on invoices outstanding more than 30 days. The Company records interest income from federal governmental agencies when received. All contract receivables are on an unsecured basis. Unbilled amounts represent costs and anticipated profits awaiting milestones to bill, contract retainages, award fees and fee withholdings, as well as amounts currently billable. In accordance with industry practice, contract receivables relating to long-term contracts are classified as current, even though portions of these amounts may not be realized within one year. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. Management has recorded an allowance for contract receivables that are considered to be uncollectible. Both billed and unbilled receivables are written off when deemed uncollectible. Recoveries of receivables previously written off are recorded when received.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Valuation of long-lived assets: The Company accounts for the valuation of long-lived assets, including amortizable intangible assets, under authoritative guidance issued by the Financial Accounting Standards Board (FASB), which requires that long-lived assets and certain intangible assets be reviewed for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the long-lived assets is measured by a comparison of the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. During the period from January 1, 2015 through November 23, 2015 and for the year ended December 31, 2014, the Company recorded an impairment loss on its customer relationships of $ 0.9 1.8
Intangible Assets, Finite-Lived, Policy [Policy Text Block]	Identifiable intangible assets: Intangible assets of the Company are comprised of customer relationships and a trade name acquired as a result of the Business Combination described further in Note 2. The Company determined that the customer relationships and trade name represent finite-lived intangible assets with useful lives of eight and fifteen years, respectively. The assets are being amortized proportionately over the term of their useful lives based on the estimated economic benefit derived over the course of the asset life.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill: The Company records the excess of the purchase price of an acquired company over the fair value of the identifiable net assets acquired as goodwill. In accordance with authoritative guidance issued by the FASB, entities can elect to use a qualitative approach to test goodwill for impairment. Under this approach, the Company performs a qualitative assessment (Step Zero) to determine whether it is more-likely-than-not that the fair value of the reporting unit is less than the carrying value. If the fair value of the reporting unit is less than the carrying value of the reporting unit, the Company is required to perform a goodwill impairment test using a two-step approach, which is performed at the reporting unit level. In the second step, the implied value of the goodwill is estimated at the fair value of the reporting unit, less the fair value of all other tangible and identifiable intangible assets of the reporting unit. If the carrying amount of the goodwill exceeds the implied fair value of the goodwill, an impairment loss is recognized in the amount equal to that excess, not to exceed the carrying amount of the goodwill. If the fair value of the reporting unit is not less than the carrying value of the reporting unit, the two-step goodwill test is not required. Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units and determination of the fair value of each reporting unit. The fair value of each reporting unit is estimated using a discounted cash flow methodology. This analysis requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for the business, estimation of the useful life over which cash flows will occur and determination of the weighted-average cost of capital. This discounted cash flow analysis is corroborated by top-down analysis, including a market assessment of enterprise value. The Company has elected to perform its annual analysis on December 31 each year at the reporting unit level and, during the Predecessor periods, had identified three reporting units with goodwill: DSTI, Seamast, and Access Systems. During the period from January 1, 2015 through November 23, 2015 and the year ended December 31, 2014, the Company recorded an impairment loss for goodwill of $ 2.1 5.1 of impairment were identified for the 41.3
Income Tax, Policy [Policy Text Block]	In connection with the Business Combination, STG Group (Predecessor) converted from a Subchapter S Corporation to a C Corporation. Prior to this, STG Group, excluding STG Netherlands and STG Doha, was treated as an S corporation under Subchapter S of the Internal Revenue Code. Therefore, in lieu of corporate income taxes, the Predecessor stockholder separately accounted for his pro-rata share of STG Group’s income, deductions, losses and credits. The Company accounts for income taxes under FASB Accounting Standards Codification (ASC) Topic 740, Income Taxes (ASC 740). At the end of each interim period, the Company estimates an annualized effective tax rate expected for the full year based on the most recent forecast of pre-tax income, permanent book and tax differences, and global tax planning strategies. The Company uses this effective rate to provide for income taxes on a year-to-date basis, excluding the effect of significant, unusual, discrete or extraordinary items, and items that are reported net of their related tax effects. The Company records the tax effect of significant, unusual, discrete or extraordinary items, and items that are reported net of their tax effects in the period in which they occur. In accordance with authoritative guidance on accounting for uncertainty in income taxes issued by the FASB, management has evaluated the Company’s tax positions and has concluded that the Company has taken no uncertain tax positions that require adjustment to the quarterly condensed consolidated financial statements to comply with the provisions of this guidance. Interest and penalties related to tax matters are recognized in expense. There was no accrued interest or penalties recorded during the year ended December 31, 2016, for the periods from November 24, 2015 through December 31, 2015 and from January 1, 2015 through November 23, 2015, and the year ended December 31, 2014. STG Group (Predecessor) is generally no longer subject to income tax examinations by the U.S. federal, state or local tax authorities for the years ended December 31, 2013, and prior.
Fair Value of Financial Instruments, Policy [Policy Text Block]	The carrying value of the Company’s cash and cash equivalents, contract receivables, line-of-credit, accounts payable and other short-term liabilities are believed to approximate fair value as of December 31, 2016 and 2015, respectively, because of the relatively short duration of these instruments. The Company also assessed long-term debt and determined that such amounts approximated fair value primarily since its terms and interest approximate current market terms and was negotiated with an unrelated third party lender. The Company considers the inputs related to these estimates to be Level 2 fair value measurements. Certain assets and liabilities are recorded at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability between market participants in an orderly transaction on the measurement date. The market in which the reporting entity would sell the asset or transfer the liability with the greatest volume and level of activity for the asset or liability is known as the principal market. When no principal market exists, the most advantageous market is used. This is the market in which the reporting entity would sell the asset or transfer the liability with the price that maximizes the amount that would be received or minimizes the amount that would be paid. Fair value is based on assumptions market participants would make in pricing the asset or liability. Generally, fair value is based on observable quoted market prices or derived from observable market data when such market prices or data are available. When such prices or inputs are not available, the reporting entity should use valuation models. The Company’s assets recorded at fair value on a recurring basis are categorized based on the priority of the inputs used to measure fair value. Fair value measurement standards require an entity to maximize the use of observable inputs (such as quoted prices in active markets) and minimize the use of unobservable inputs (such as appraisals or other valuation techniques) to determine fair value. The inputs used in measuring fair value are categorized into three levels, as follows: Level 1: Inputs that are based upon quoted prices for identical instruments traded in active markets. Level 2: Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar investments in markets that are not active, or models based on valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the investment. Level 3: Inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models and similar techniques. As of December 31, 2016 and 2015, the Company has no financial assets or liabilities that are categorized as Level 3. The Company has investments carried at fair value in mutual funds held in a Rabbi Trust, which is included in investments held in Rabbi Trust on the accompanying consolidated balance sheets. The Company does not measure non-financial assets and liabilities at fair value unless there is an event which requires this measurement.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Financial credit risk: The Company’s assets that are exposed to credit risk consist primarily of cash and cash equivalents, investments held in Rabbi Trust and contract receivables. Cash and cash equivalents are deposited with high-credit, quality financial institutions whose balances may, at times, exceed federally insured limits. The Company has not experienced any losses in such amounts and believes that it is not exposed to any significant credit risk on cash and cash equivalents. Investments held in Rabbi Trust are stated at fair value at each reporting period and are subject to market fluctuations. Contract receivables consist primarily of amounts due from various agencies of the federal government or prime contractors doing business with the federal government. Historically, the Company has not experienced significant losses related to contract receivables and, therefore, believes that the credit risk related to contract receivables is minimal.
Debt issuance costs [Policy Text Block]	In April 2015, the FASB issued Accounting Standards Update (ASU) 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs 6.4 1.4 0.1
Business Combinations and Other Purchase of Business Transactions, Policy [Policy Text Block]	Transaction-related expenses: The Company incurs transaction-related expenses primarily consisting of professional service fees and costs related to business acquisition activities. The Company recognized transaction-related expenses of approximately $ 2.6 0.6 0.89 the pending transaction disclosed further in Note 15.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock based compensation: The Company measures compensation expense for stock based equity awards based on the fair value of the awards on the grant date. Compensation is recognized as expense in the accompanying consolidated statements of operations ratably over the required service period or, for performance based awards, when the achievement of the performance targets become probable.
Earnings Per Share, Policy [Policy Text Block]	Net (loss) income per share: Basic net (loss) income per share available to common shareholders of the Company is calculated by dividing the net (loss) income by the weighted average number of common shares outstanding during the year. Common shares issuable upon exercise of the stock options and future vesting of the restricted stock awards (see Note 12) have not been included in the computation because their inclusion would have had an antidilutive effect for all periods presented.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent accounting pronouncements: In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) In August 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. 4.5 10.9 6.4 In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842 In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting (ASU 2016-09) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force), In January 2017, the FASB issued ASU 2017-01, " Business Combinations (Topic 805) Clarifying the Definition of a Business", Business Combinations In January 2017, the FASB issued ASU No. 2017-04 “Intangibles-Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 provides guidance to simplify the subsequent measurement of goodwill by eliminating the Step 2 procedure from the goodwill impairment test. Under the updates in ASU 2017-04, an entity should perform its annual or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments of this ASU are effective for annual or any interim goodwill impairment tests beginning after December 15, 2019. The Company has not yet evaluated the impact, if any, that the adoption of ASU 2017-04 will have on our Consolidated Financial Statements.
