Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1. Organization and Business Operations GTY Technology Holdings, Inc. (the "Company", or "GTY") was formed as a blank check company incorporated on August 11, 2016 as a Cayman Islands exempted company formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “business combination”). Until the business combination, GTY did not engage in any operations nor generated any revenue. All activities through December 31, 2018 relate to the Company’s formation and the initial public offering (as defined below) and, since the closing of the initial public offering, a search for business combination candidates described below. The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies. GTY consummated the initial public offering (the “initial public offering”) of 55,200,000 units, including the issuance of 7,200,000 units as a result of the underwriters’ exercise of their over-allotment option in full at $10.00 per unit on November 1, 2016, generating gross proceeds of $552 million. GTY incurred offering costs of approximately $31 million, inclusive of approximately $30.4 million of underwriting fees. The Company paid $11.04 million of underwriting fees upon the closing of the initial public offering and deferred $19.32 million of underwriting fees until the consummation of the initial business combination. Simultaneously with the closing of the initial public offering, the Company consummated the private placement (“private placement”) of 8,693,334 warrants (“private placement warrants”) at a price of $1.50 per private placement warrant with the Company’s sponsor, GTY Investors, LLC, a Delaware limited liability company (the “Sponsor”), generating gross proceeds of approximately $13.04 million (Note 4). Upon the closing of the initial public offering and private placement on November 1, 2016, $552 million from the net proceeds of the sale of the units in the initial public offering and the private placement was placed in a U.S.-based trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee (“Trust Account”). The funds in the Trust Account were invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with maturities of 180 days or less or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of paragraphs (d)(2), (d)(3) and (d)(4) of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the completion of the business combination. The Company provided its holders of the outstanding Class A ordinary shares sold in the initial public offering (“public shareholders”) with the opportunity to redeem all or a portion of their public shares in connection with a shareholder meeting called to approve the business combination. The public shareholders are entitled to redeem their public shares for a pro rata portion of the amount then in the Trust Account. The per-share amount to be distributed to public shareholders who redeem their public shares was not reduced by the deferred underwriting commissions the Company paid to the underwriters (as discussed in Note 5). These public shares will be recorded at a redemption value and classified as temporary equity upon the completion of the initial public offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480 “ Distinguishing Liabilities from Equity .” Initially, GTY was required to complete its initial business combination by November 1, 2018, which was 24 months from the closing of its initial public offering. On October 30, 2018, GTY’s shareholders approved a proposal to amend GTY’s second amended and restated memorandum and articles of association to extend the date by which it had to consummate an initial business combination from November 1, 2018 to May 1, 2019 (the “Combination Period”). In connection with such proposal, GTY’s public shareholders had the right to elect to redeem their public shares for a per share price, payable in cash, based upon the aggregate amount then on deposit in the trust account. GTY’s public shareholders holding 34,011,538 Class A ordinary shares out of a total of 55,200,000 Class A ordinary shares validly elected to redeem their public shares and, accordingly, after giving effect to such redemptions, the balance in GTY’s Trust Account was approximately $216.8 million. If the Company was unable to complete a business combination by May 1, 2019, the Company would have (i) ceased all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter, redeem 100% of the outstanding public shares which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Company’s board of directors, proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company, subject in each case to its obligations to provide for claims of creditors and the requirements of applicable law. In connection with the redemption of 100% of the Company’s outstanding public shares for a portion of the funds held in the Trust Account, each holder would have received a full pro rata portion of the amount then in the Trust Account, plus any pro rata interest earned on the funds held in the Trust Account (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable). The initial shareholders agreed to waive their liquidation rights with respect to the founder shares if the Company fails to complete a business combination within the Combination Period. However, if the initial shareholders should acquire public shares in or after the initial public offering, they will be entitled to liquidating distributions from the Trust Account with respect to such public shares if the Company fails to complete a business combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a business combination within in the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Company’s public shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the sponsor has agreed to be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent public accountants) for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per public share due to reductions in the value of the trust assets, less taxes payable. This liability will not apply with respect to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) or to any claims under the Company’s indemnity of the underwriters of the initial public offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor must indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s registered independent public accounting firms), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. On September 12, 2018 (and under subsequent amendments and/or amendments and restatements thereto), GTY entered into the following agreements: (1) an Agreement and Plan of Merger (the “GTY Agreement”) with GTY Technology Holdings Inc., a Massachusetts corporation and a wholly-owned subsidiary of GTY (“New GTY”) and GTY Technology Merger Sub, Inc., a newly formed wholly-owned subsidiary of New GTY; (2) an Arrangement Agreement with Bonfire Interactive Ltd. (“Bonfire”), 1176370 B.C. Unlimited Liability Company, 1176363 B.C. Ltd. and the Bonfire Holders’ Representative named therein (the “Bonfire Agreement” and the transactions contemplated by the Bonfire Agreement, the “Bonfire Transaction”); (3) an Agreement and Plan of Merger with CityBase, Inc. (“CityBase”), New GTY, GTY CB Merger Sub, Inc. (“CityBase Merger Sub”) and Shareholder Representative Services LLC (the “CityBase Agreement” and the transactions contemplated by the CityBase Agreement, the “CityBase Transaction”); (4) an Agreement and Plan of Merger with eCivis Inc. (“eCivis”), GTY EC Merger Sub, Inc. (“eCivis Merger Sub”) and the eCivis Holders’ Representative named therein (the “eCivis Agreement” and the transactions contemplated by the eCivis Agreement, the “eCivis Transaction”); (5) an Agreement and Plan of Merger with Open Counter Enterprises Inc. (“OpenCounter”), GTY OC Merger Sub, Inc. (“OpenCounter Merger Sub”) and Shareholder Representative Services LLC (the “OpenCounter Agreement” and the transactions contemplated by the OpenCounter Agreement, the “OpenCounter Transaction”); (6) a Share Purchase Agreement with Questica Inc. and Questica USCDN Inc. (together, “Questica”), Exchangeco and each of the Questica Holders named therein (the “Questica Agreement” and the transactions contemplated by the Questica Agreement, the “Questica Transaction”); and (7) a Unit Purchase Agreement with Sherpa Government Solutions LLC (“Sherpa”), the holders of the issued and outstanding shares of capital stock of Sherpa (“Sherpa Units”) named therein (the “Sherpa Holders”) and the Sherpa Holders’ Representative named therein (the “Sherpa Agreement” and the transactions contemplated by the Sherpa Agreement, the “Sherpa Transaction”). Bonfire, CityBase, eCivis, OpenCounter, Questica and Sherpa are collectively referred to herein as the “Targets.” The Bonfire Agreement, CityBase Agreement, eCivis Agreement, OpenCounter Agreement, Questica Agreement, Sherpa Agreement and GTY Agreement are collectively referred to herein as the “Transaction Documents.” The transactions contemplated by the Transaction Documents are collectively referred to herein as the “business combination.” On February 15, 2019, the business combination was approved by the shareholders of GTY at the extraordinary general meeting of shareholders. In connection with the business combination, 11,073,040 Class A ordinary shares of GTY were redeemed at a per share price of approximately $10.29. On February 19, 2019 (the “Closing Date”), the Company consummated the business combination, pursuant to which New GTY acquired each of the six Targets mentioned above. In connection with the closing of the business combination (the “Closing”), pursuant to the GTY Agreement, GTY Merger Sub merged with and into GTY, with GTY surviving the merger as a direct, wholly-owned subsidiary of New GTY (the “GTY Merger”). Immediately after the Closing, the Company had 48,511,028 shares of common stock outstanding and 27,093,316 warrants outstanding. Upon the consummation of the GTY Merger, each outstanding Class A ordinary share of GTY was cancelled and exchanged for one share of New GTY common stock in accordance with the terms of the GTY Agreement. Each Class B Ordinary Share was converted into one Class A Ordinary Share immediately prior to the consummation of the GTY Merger in accordance with GTY’s second amended and restated memorandum and articles of association, following which each Class A Ordinary Share issued upon conversion of the Class B ordinary shares was then cancelled and exchanged for one share of New GTY common stock. In addition, GTY’s outstanding warrants were assumed by New GTY and became exercisable for shares of New GTY common stock on the same terms as were contained in such warrants prior to the GTY Merger. Further information regarding the business combination and GTY is set forth in (i) the proxy statement/prospectus included in New GTY’s registration statement on Form S-4 (File No. 333-229189) as amended and supplemented, originally filed with the SEC on January 11, 2019 and (ii) New GTY’s Current Report on Form 8-K filed with the SEC on February 19, 2019, as amended by New GTY’s Current Report on Form 8- K12B/A filed with the SEC on March 18, 2019.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 2. Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the Company’s accounts. All material intercompany transactions and balances have been eliminated in the accompanying consolidated financial statements. Basis of Presentation The accompanying consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that 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. This may make comparison of the Company’s consolidated financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accountant standards used. Cash and Cash Equivalents Held in Trust Account The amounts held in the Trust Account represent substantially all of the proceeds of the initial public offering and are classified as restricted assets since such amounts can only be used by the Company in connection with the consummation of a business combination. As of December 31, 2018 and 2017, cash and marketable securities, are classified as trading securities, held in the Trust Account consisted of approximately $217.6 million and $556.8 million in U.S. Treasury Bills and approximately $600 and $1,000 in cash, respectively. At December 31, 2018 and 2017, there was approximately $13.6 million and $4.8 million, respectively, of interest income held in the Trust Account available to be released to the Company to pay income taxes. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of cash accounts in a financial institution which, at times may exceed the Federal depository insurance coverage of $250,000. At December 31, 2018 and 2017, the Company had not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Use of Estimates The preparation of the consolidated financial statements and related disclosures in conformity with U.S. GAAP 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 balance sheets and the reported amounts of revenue and expenses during the reporting periods. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC Topic 480 “ Distinguishing Liabilities from Equity ”. Ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, an aggregate of 20,289,478 and 53,295,619 Class A ordinary shares subject to possible redemption at redemption value at December 31, 2018 and 2017, respectively, are presented as temporary equity, outside of the shareholders’ equity section of the Company’s accompanying consolidated balance sheets. Net Income per Share Net income per share is computed by dividing net income by the weighted-average number of ordinary shares outstanding during the period. An aggregate of 20,289,478 20,289,478 Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC 740, “Income Taxes” (“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. Based on its analysis, the Company has determined that it has not incurred any liability for unrecognized tax benefits as of December 31, 2018 and 2017. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties at December 31, 2018 and 2017. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman federal income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s consolidated financial statements. The Company’s management expects that the total amount of unrecognized tax benefits will materially change over the next twelve months in connection with the business combination consummated in February 2019. Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:  Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets;  Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and  Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. ASC 820, Fair Value Measurement and Disclosures , requires all entities to disclose the fair value of financial instruments, both assets and liabilities for which it is practicable to estimate fair value, and defines fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties. As of December 31, 2018 and 2017, the recorded values of cash, cash and cash equivalents held in the Trust Account, prepaid expenses, accounts payable, and accrued expenses approximate the fair values due to the short-term nature of the instruments. Recent Accounting Pronouncements In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed. The Company anticipates its first presentation of the revised presentation of changes in stockholders' equity will be included in its Form 10-Q for the quarter ended March 31, 2019. In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, "Leases," (“ASC 842”) which amends existing guidance to require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. The new standard establishes a right-of-use model ("ROU") that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with an initial term longer than twelve months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company adopted ASC 842 effective January 1, 2019 and has elected the short-term lease recognition exemption for all leases that qualify. The Company does not expect the impact to be material. Management does not believe that any other recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s consolidated financial statements.

Initial Public Offering [Text Block]	Note 3. Initial Public Offering On November 1, 2016, the Company sold 55,200,000 units at a purchase price of $10.00 per unit in the initial public offering, including the issuance of 7,200,000 units as a result of the underwriters’ exercise of their over-allotment option in full. Each unit consisted of one Class A ordinary share and one-third of one redeemable warrant (“public warrant”). Each whole public warrant entitled the holder to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment (see Note 6). The Company incurred offering costs of approximately $31 million, inclusive of approximately $30.36 million of underwriting fees. The Company paid $11.04 million of underwriting fees upon the closing of the initial public offering and deferred $19.32 million of underwriting fees until the consummation of the initial business combination.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	Note 4. Related Party Transactions Founder Shares The Company initially issued 8,625,000 Class B ordinary shares as of August 17, 2016. On October 14 and October 26, 2016, the Company effected a share capitalization resulting in an aggregate of 11,500,000 and 13,800,000 founder shares outstanding, respectively. In October 2016, the Sponsor transferred 25,000 founder shares to each of the Company’s independent director nominees at the same per-share purchase price paid by the Sponsor. As a result of the underwriters’ exercise of their over-allotment option, no founder shares were surrendered to the Company by the Sponsor. The founder shares automatically converted into common stock upon the consummation of the business combination on a one-for-one basis. The Sponsor and GTY’s officers and directors agreed not to transfer, assign or sell any of the founder shares (except to certain permitted transferees) until the earlier to occur of (i) one year after the completion of the business combination, or earlier if, subsequent to the business combination, the closing price of New GTY’s common stock equals or exceeds $12.00 per share for any 20 trading days within any 30-trading day period commencing 150 days after the completion of the business combination and (ii) the date following the completion of the business combination on which New GTY completes a liquidation, merger, share exchange or other similar transaction which results in all of New GTY’s stockholders having the right to exchange their common stock for cash, securities or other property. Private Placement Warrants Concurrently with the closing of the initial public offering, the Sponsor purchased an aggregate of 8,693,334 private placement warrants at $1.50 per warrant and generated gross proceeds of $13.04 million in the private placement. Due to Related Party To finance transaction costs in connection with an initial business combination, the Sponsor or an affiliate of the Sponsor, or certain of GTY’s officers and directors were able, but were not obligated to, loan us funds as may be required (“Working Capital Loans”). On August 8, 2018, the Sponsor agreed to provide up to $1 million in Working Capital Loans in the form of a convertible note (the “Convertible Note”). Amounts outstanding under the Convertible Note may be convertible into warrants at a price of $1.50 per warrant at the option of the lender. The warrants would be identical to the private placement warrants. Prior to the completion of GTY’s initial business combination, we did not seek loans from parties other than the Sponsor or an affiliate of the Sponsor as we did not believe third parties would be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in GTY’s Trust Account. As of December 31, 2018, we borrowed $600,000 under the Convertible Note. To date, the Convertible Note still remains outstanding. Administrative Service Fee The Company agreed to reimburse the Sponsor in an amount not to exceed $10,000 per month for office space, and secretarial and administrative services through the earlier of the Company’s consummation of a business combination and its liquidation. The Company recognized $120,000 for each of the years ended December 31, 2018 and 2017, respectively in connection with this agreement in the accompanying consolidated statements of operations. The Company paid an aggregate of $200,000 in administrative fees to the Sponsor in August 2018. As of December 31, 2018 and 2017, the Company had a total of $60,000 and $140,000 in administrative fees payable to the Sponsor, respectively.

Commitments and Contingencies Underwriting Agreement Pursuant to the underwriting agreement relating to the initial public offering (the “Underwriting Agreement”), GTY paid an underwriting discount of $0.20 per unit, or $11.04 million in the aggregate, upon the consummation of the Initial Public Offering. An additional fee of $0.35 per unit, or $19.32 million in the aggregate will be payable to the underwriters for deferred underwriting fees from the amounts held in the Trust Account, subject to the terms of the underwriting agreement. In January 2019, the Company amended the Underwriting Agreement and reduced the deferred underwriting fees to $3.25 million payable in cash, which was reflected in the accompanying consolidated balance sheets (Note 8). The Company paid off this amount upon consummation of the business combination in February 2019.

Stockholders' Equity Note Disclosure [Text Block]	Note 6. Shareholders’ Equity Class A Ordinary Shares – GTY was authorized to issue 400,000,000 shares of Class A ordinary shares with a par value of $0.0001 per share. At December 31, 2018 and 2017, there were 21,188,462 and 55,200,000 Class A ordinary shares issued and outstanding, including 20,289,478 and 53,295,619 shares of Class A ordinary shares subject to possible redemption, respectively. Class B Ordinary Shares – GTY was authorized to issue 50,000,000 shares of Class B ordinary shares with a par value of $0.0001 per share. As of December 31, 2018 and 2017, the Company had 13,800,000 Class B ordinary shares issued and outstanding. Holders of Class A ordinary shares and Class B ordinary shares voted together as a single class on all other matters submitted to a vote of shareholders except as required by law. Preferred Shares – GTY was authorized to issue 1,000,000 preferred shares with a par value of $0.0001 per share. At December 31, 2018 and 2017, there were no preferred shares issued or outstanding. Warrants th The private placement warrants are identical to the public warrants underlying the units sold in the initial public offering, except that the private placement warrants and the shares issuable upon exercise of the private placement warrants were not transferable, assignable or salable until 30 days after the completion of the business combination, subject to certain limited exceptions. Additionally, the private placement warrants will be non-redeemable so long as they are held by the initial purchasers or such purchasers’ permitted transferees. If the private placement warrants are held by someone other than the initial shareholders or their permitted transferees, the private placement warrants will be redeemable by the Company and exercisable by such holders on the same basis as the public warrants. The Company may call the public warrants for redemption (except with respect to the private placement warrants):  in whole and not in part;  at a price of $0.01 per warrant;  upon a minimum of 30 days’ prior written notice of redemption; and  if, and only if, the last reported closing price of the Company’s shares equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders. If the Company calls the public warrants for redemption, management will have the option to require all holders that wish to exercise the public warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of shares issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a share dividend, or recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrants shares.

Subsequent Events [Text Block]	Note 8. Subsequent Events Business Combination On February 19, 2019, New GTY consummated the business combination, pursuant to which New GTY acquired each of Bonfire, CityBase, eCivis, Open Counter, Questica, and Sherpa. In connection with the closing of the business combination (the “Closing”), pursuant to the GTY Agreement between New GTY, GTY, and GTY Merger Sub, GTY Merger Sub merged with and into GTY, with GTY surviving the merger as a direct, wholly-owned subsidiary of New GTY, and in connection therewith New GTY changed its name from GTY Govtech, Inc. to GTY Technology Holdings Inc. Upon the Closing, all outstanding Class A ordinary shares were exchanged on a one-for-one basis for shares of New GTY common stock, and GTY’s outstanding warrants were assumed by New GTY and became exercisable for shares of New GTY common stock on the same terms as were contained in such warrants prior to the business combination. By operation of Rule 12g-3(a) under the Exchange Act, New GTY is the successor issuer to GTY and has succeeded to the attributes of GTY as the registrant, including GTY’s SEC file number 001-37931 and CIK Code 0001682325. In connection with the business combination, 11,073,040 Class A ordinary shares were redeemed at a per share price of approximately $10.29. Upon the Closing, New GTY had 48,511,028 shares of common stock outstanding. Upon the Closing, New GTY became a holding company whose assets primarily consist of shares of its wholly owned subsidiaries. Subscription Agreement Immediately prior to the Closing, pursuant to subscription agreements (the “Subscription Agreements”), dated as of various dates from January 9, 2019 through February 12, 2019, by and among GTY and certain institutional and accredited investors party thereto (the “Subscribed Investors”), GTY issued to the Subscribed Investors an aggregate of 12,853,633 Class A ordinary shares of GTY for $10.00 per share, for an aggregate cash purchase price of approximately $126.3 million, including three such Subscription Agreements with certain CityBase holders (including Michael Duffy, the chief executive officer of CityBase) for an aggregate of 380,937 Class A ordinary shares of GTY at a price of $10.00 per share, for an aggregate cash purchase price of approximately $3.8 million. The Class A ordinary shares of GTY issued to the Subscribed Investors were cancelled and exchanged on a one-for-one basis for shares of Company common stock at the Closing. In connection with the Subscription Agreements, immediately prior to the Closing, the Sponsor surrendered to GTY for cancellation at no cost to GTY 231,179 founder shares and sold 500,000 private placement warrants held by it to an accredited investor in a private placement for an aggregate of $250,000 or $0.50 per warrant (which was $1.00 per warrant less than the price originally paid for such warrants). Amended Underwriting Agreement In January 2019, the Company amended the Underwriting Agreement, pursuant to which the deferred underwriting fees of $19.32 million were reduced to $3.25 million payable in cash. The Company paid off this amount upon consummation of the business combination in February 2019. Amended Charter In connection with the GTY Merger, GTY merged with a wholly owned subsidiary of New GTY formed in Delaware, with GTY surviving the merger as a wholly owned subsidiary of New GTY. In connection with the Closing, New GTY amended its articles of organization (as so amended, the “Amended Charter”) on February 15, 2019 and adopted bylaws on February 19, 2019. Pursuant to the Amended Charter, the Company has authorized the issuance of 425,000,000 shares of capital stock, consisting of (x) 400,000,000 shares of common stock, $0.0001 par value per share, and (y) 25,000,000 shares of preferred stock, par value $0.0001 per share. Immediately following the Closing, there were 48,511,028 shares of the Company’s common stock issued and outstanding. Agreements and Arrangements with Certain Institutional Investors On February 13, 2019, GTY, the Sponsor, William D. Green, Joseph M. Tucci and Harry L. You (Messrs. Green, Tucci and You, collectively, the “Founders”) entered into agreements and arrangements with certain institutional investors pursuant to which a total of 1,500,000 Class A Ordinary Shares were not redeemed in connection with the business combination. An aggregate of 500,000 of such shares are subject to a lock-up pursuant to which such shares may not be transferred until the 91st day following Closing without the consent of GTY and the Founders, and the holder of such shares is entitled to put such shares to the Sponsor and the Founders following the lock-up period for a purchase price equal to the price at which GTY redeemed Class A Ordinary Shares in connection with the business combination, $10.29 (the “redemption price”), payment of which purchase price is guaranteed by GTY, and to receive from GTY a cash payment, if and to the extent necessary, but not to exceed $250,000, in order to provide such shareholder with at least a 5% return on such shares above the redemption price. With respect to 1,000,000 of such shares, GTY engaged a broker-dealer to facilitate the purchase of such shares by an institutional investor prior to the Closing for $9.90 per share and agreed to pay such broker-dealer an amount in cash equal to the difference between the redemption price and $9.90. In addition, the Sponsor and the Founders entered into agreements prior to the Closing pursuant to which they are obligated to reimburse the holders of 1,942,953 Class A Ordinary Shares that were not redeemed in connection with the business combination for losses that may be incurred upon the sale of such shares within a specified period following the Closing, up to an agreed-upon limit, and GTY has agreed to guarantee such reimbursement obligations. Related Party Loans Subsequent to December 31, 2018, the Sponsor lent the Company an additional of $400,000, for a total of $1 million under the Convertible Note.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The consolidated financial statements include the Company’s accounts. All material intercompany transactions and balances have been eliminated in the accompanying consolidated financial statements.
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC.
Start-up Activities, Cost Policy [Policy Text Block]	Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that 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. This may make comparison of the Company’s consolidated financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accountant standards used.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Held in Trust Account The amounts held in the Trust Account represent substantially all of the proceeds of the initial public offering and are classified as restricted assets since such amounts can only be used by the Company in connection with the consummation of a business combination. As of December 31, 2018 and 2017, cash and marketable securities, are classified as trading securities, held in the Trust Account consisted of approximately $217.6 million and $556.8 million in U.S. Treasury Bills and approximately $600 and $1,000 in cash, respectively. At December 31, 2018 and 2017, there was approximately $13.6 million and $4.8 million, respectively, of interest income held in the Trust Account available to be released to the Company to pay income taxes.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of cash accounts in a financial institution which, at times may exceed the Federal depository insurance coverage of $250,000. At December 31, 2018 and 2017, the Company had not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of the consolidated financial statements and related disclosures in conformity with U.S. GAAP 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 balance sheets and the reported amounts of revenue and expenses during the reporting periods. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.
Shares Subject to Mandatory Redemption, Changes in Redemption Value, Policy [Policy Text Block]	Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC Topic 480 “ Distinguishing Liabilities from Equity ”. Ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, an aggregate of 20,289,478 and 53,295,619 Class A ordinary shares subject to possible redemption at redemption value at December 31, 2018 and 2017, respectively, are presented as temporary equity, outside of the shareholders’ equity section of the Company’s accompanying consolidated balance sheets.
Earnings Per Share, Policy [Policy Text Block]	Net Income per Share Net income per share is computed by dividing net income by the weighted-average number of ordinary shares outstanding during the period. An aggregate of 20,289,478 20,289,478
Income Tax, Policy [Policy Text Block]	Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC 740, “Income Taxes” (“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. Based on its analysis, the Company has determined that it has not incurred any liability for unrecognized tax benefits as of December 31, 2018 and 2017. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties at December 31, 2018 and 2017. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman federal income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s consolidated financial statements. The Company’s management expects that the total amount of unrecognized tax benefits will materially change over the next twelve months in connection with the business combination consummated in February 2019.
Fair Value Measurement, Policy [Policy Text Block]	Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:  Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets;  Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and  Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. ASC 820, Fair Value Measurement and Disclosures , requires all entities to disclose the fair value of financial instruments, both assets and liabilities for which it is practicable to estimate fair value, and defines fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties. As of December 31, 2018 and 2017, the recorded values of cash, cash and cash equivalents held in the Trust Account, prepaid expenses, accounts payable, and accrued expenses approximate the fair values due to the short-term nature of the instruments.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed. The Company anticipates its first presentation of the revised presentation of changes in stockholders' equity will be included in its Form 10-Q for the quarter ended March 31, 2019. In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, "Leases," (“ASC 842”) which amends existing guidance to require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. The new standard establishes a right-of-use model ("ROU") that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with an initial term longer than twelve months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company adopted ASC 842 effective January 1, 2019 and has elected the short-term lease recognition exemption for all leases that qualify. The Company does not expect the impact to be material. Management does not believe that any other recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s consolidated financial statements.
