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.

Going Concern and Liquidity [Text Block]	Note 2. Going Concern and Liquidity The Company’s condensed consolidated financial statements have been prepared assuming that it will continue as a going concern, which contemplates continuity of operations, realization of assets, and liquidation of liabilities in the normal course of business. As reflected in the condensed consolidated financial statements, the Company had an accumulated deficit of approximately $35.1 million at March 31, 2019, a net loss of approximately $40.1 million and approximately $25.3 million net cash used in operating activities for the successor period from February 19, 2019 through March 31, 2019. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The Company is attempting to further expand its customer base; scale up its production of various products; and increase revenue; however, the Company’s cash position may not be sufficient to support its daily operations through the next twelve months from the date of filing this 10-Q. The ability of the Company to continue as a going concern is dependent upon its ability to raise additional funds by way of a public or private offering and its ability to further generate sufficient revenue. While the Company believes in the viability of its platform and in its ability to raise additional funds by way of a public or private offering, there can be no assurances to that effect. The condensed consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

Summary of Significant Accounti

Summary of Significant Accounting Policies	3 Months Ended	12 Months Ended
	Mar. 31, 2019	Dec. 31, 2018
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 3. Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Certain information and disclosures normally included in condensed consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The accompanying condensed consolidated financial statements should be read in conjunction with the Company's audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 filed with the Securities and Exchange Commission (“SEC”) on March 18, 2019 and the Company’s Current Report Form 8-K/A filed with the SEC on March 18, 2019. The Acquisition was accounted for as a business combination using the acquisition method of accounting. The Company’s financial statement presentation distinguishes the results of operations into two distinct periods: (i) the period before the consummation of the Acquisition, which includes the period from January 1, 2019 to the Closing Date (the “2019 Predecessor Period”) and the three months ended March 31, 2018 (the “2018 Predecessor Period”) and (ii) the period after consummation of the Acquisition which includes the period including and after the Closing Date to March 31, 2019 (the “Successor Period”). The accompanying condensed consolidated financial statements include a black line division which indicates that the Acquired Companies and the Company’s financial information are presented on a different basis and are therefore, not comparable. Determining the fair value of certain assets and liabilities assumed is judgmental in nature and often involves the use of significant estimates and assumptions. See Note 4 – Business Combination for a discussion of the estimated fair values of assets and liabilities recorded in connection with the Acquisition. The historical financial information of GTY Cayman prior to the Acquisition is not being reflected in the Predecessor financial statements as these historical amounts have been determined not to be useful to a user of the financial statements. GTY Cayman’s operations prior to the Acquisition, other than income from the Trust Account investments and transaction expenses, were nominal. The Company believes that Predecessor activities related to investments, intangible assets, stock-based compensation, goodwill, fair value measurements and notes payable were either quantitatively or qualitatively immaterial. Therefore, the Company did not disclose these Predecessor activities in the following unaudited footnotes. Principles of Consolidation The Successor Period condensed consolidated financial statements include all accounts of the Company and its subsidiaries. The Predecessor Period condensed consolidated financial statements include all accounts of the Acquired Companies and the Acquired Companies’ subsidiaries. All material intercompany transactions and balances have been eliminated in the accompanying condensed consolidated financial statements. Segments The Company has six operating segments. The Company’s Chief Executive Officer and Chief Financial Officer, who jointly are the Company’s chief operating decision maker, review financial information for each of the Acquired Companies, together with certain operating metrics principally to make decisions about how to allocate resources and to measure the Company’s performance. See Note 12. Cash and Cash Equivalents The Company considers all highly liquid investments with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents. Cash includes cash held in checking and savings accounts. Cash equivalents are comprised of investments in money market mutual funds. Cash and cash equivalents are recorded at cost, which approximates fair value. Accounts Receivable Accounts receivable consists of amounts due from our customers, which are primarily located throughout the United States and Canada. Accounts receivable are recorded at the invoiced amount, do not require collateral, and do not bear interest. The Company estimates its allowance for doubtful accounts by evaluating specific accounts where information indicates the Company’s customers may have an inability to meet financial obligations, such as bankruptcy and significantly aged receivables outstanding. Uncollectible receivables are written-off in the period management believes it has exhausted every opportunity to collect payment from the customer. Bad debt expense is recorded when events or circumstances indicate an additional allowance is required based on the Company’s specific identification approach. The allowance for doubtful accounts for the Successor as of March 31, 2019 and for the Predecessor as of December 31, 2018 was immaterial. Bad debt expense for the period from February 19, 2019 to March 31, 2019 (Successor), the period from January 1, 2019 to February 18, 2019 (Predecessor) and the three months ended March 31, 2018 (Predecessor) was immaterial. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of cash and cash equivalents, and accounts receivable. Cash accounts in a financial institution at times may exceed the Federal depository insurance coverage of $250,000. As of March 31, 2019 and December 31, 2018, the Company had not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Additionally, all Canadian Dollars (“CDN”) institution amounts are covered by Canada Deposit Insurance Corporation, or CDIC insurance. Use of Estimates The preparation of the condensed 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 revenues and expenses during the reporting periods. Significant items subject to such estimates include revenue recognition, the carrying value of goodwill, the fair value of acquired intangibles, the capitalization of software development costs, and the useful lives intangible assets, stock-based compensation, contingent consideration and the valuation allowance of deferred tax assets resulting from net operating losses. Property and Equipment Property and equipment are recorded at cost. Maintenance and repairs are charged to expense as incurred, and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gain or loss is reflected in the condensed consolidated statement of operations in the period realized. Property, plant and equipment is depreciated using the straight-line method over 5 to 15 years. Internal-use software is amortized on a straight-line basis over its estimated useful life or 5 years. Leasehold improvements are amortized over the shorter of the useful lives or the term of the respective leases. Depreciation expense recognized by the Company for the period from February 19, 2019 to March 31, 2019 (Successor) was $0.1 million. Depreciation expense recognized by the Predecessor for the period from January 1, 2019 through February 18, 2018 and the three months ended March 31, 2018 was $0.2 million and $0.2 million, respectively. Capitalized Software Costs The Company capitalizes costs incurred during the application development stage related to the development of internal-use software and enterprise cloud computing services. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Intangible Assets (Successor) Intangible assets consist of acquired customer relationships, acquired developed technology, trade name and non-compete agreements which were acquired as part of the Acquisition. The Company determines the appropriate useful life of its intangible assets by performing an analysis of expected cash flows of the acquired assets. Intangible assets are amortized over their estimated useful lives using the straight-line method, which approximates the pattern in which the economic benefits are consumed. Goodwill (Successor) Goodwill represents the excess of the purchase price of an entity over the estimated fair value of the assets acquired and liabilities assumed, and it is presented as Goodwill in the accompanying condensed consolidated balance sheet of the Successor. Under ASC 350, Intangibles – Goodwill and Other Business Combinations (Successor) The Company accounts for business acquisitions using the acquisition method of accounting based on Accounting Standards Codification (“ASC”) 805 — Business Combinations, which requires recognition and measurement of all identifiable assets acquired and liabilities assumed at their fair value as of the date control is obtained. The Company determines the fair value of assets acquired and liabilities assumed based upon its best estimates of the acquisition-date fair value of assets acquired and liabilities assumed in the acquisition. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired. Subsequent adjustments to fair value of any contingent consideration are recorded to the Company’s condensed consolidated statements of operations. Impairment of long-lived assets The Company reviews long-lived assets, including property and equipment and intangible assets and goodwill for impairment whenever events or changes in business circumstances indicate that the carrying amount of an asset may not be fully recoverable. An impairment loss is recognized when the asset’s carrying value exceeds the total undiscounted cash flows expected from its use and eventual disposition. The amount of the impairment loss is determined as the excess of the carrying value of the asset over its fair value. Leases Effective January 1, 2019, the Company accounts for its leases under ASC 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases, and are recorded on the condensed consolidated balance sheet as both a right of use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right of use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right of use asset result in straight-line rent expense over the lease term. Variable lease expenses are recorded when incurred. In calculating the right of use asset and lease liability, the Company elects to combine lease and non-lease components. The Company excludes short-term leases having initial terms of 12 months or less from the new guidance as an accounting policy election, and recognizes rent expense on a straight-line basis over the lease term. The Company continues to account for leases prior to January 1, 2019 under ASC Topic 840. Fair Value (Successor) The fair value of an asset or liability is the price that would be received to sell an asset or transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value and defines three levels of inputs that may be used to measure fair value . • Level 1 — uses quoted prices in active markets for identical assets or liabilities. • Level 2 — uses observable inputs other than quoted prices in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 — uses one or more significant inputs that are unobservable and supported by little or no market activity, and that reflect the use of significant management judgment. The Company’s only material financial instruments carried at fair value as of March 31, 2019, with changes in fair value flowing through current earnings, consist of contingent consideration liabilities recorded in conjunction with business combinations, as follows (in thousands): Fair Value Measurement at Reporting Date Using Balance as of March 31, 2019 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Contingent consideration – current $ 11,515 $ - $ - $ 11,515 Contingent consideration – long term 56,333 - - 56,333 Total liabilities measured at fair value $ 67,848 $ - $ - $ 67,848 There were no transfers made among the three levels in the fair value hierarchy during the three months ended March 31, 2019. The following table presents additional information about Level 3 liabilities measured at fair value. Both observable and unobservable inputs may be used to determine the fair value of positions that the Company has classified within the Level 3 category. As a result, the unrealized gains and losses for liabilities within the Level 3 category may include changes in fair value that were attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long-dated volatilities) inputs. Changes in Level 3 liabilities measured at fair value from February 18, 2019 to March 31, 2019 (in thousands): Contingent consideration - February 18, 2019 $ 2,031 Fair value of contingent consideration – Bonfire 325 Fair value of contingent consideration – CityBase 48,410 Fair value of contingent consideration – eCivis 5,859 Fair value of contingent consideration - Questica 9,311 Fair value of contingent consideration – Sherpa 1,898 Change due to fluctuation in foreign currency 14 Contingent consideration - March 31, 2019 $ 67,848 There was no a material change in fair value of contingent consideration from the Acquired Companies acquisitions through March 31, 2019. The fair value of the Company’s contingent consideration liabilities recorded as part of the acquisitions has been classified within Level 3 in the fair value hierarchy. The contingent consideration represents the estimated fair value of future payments due to the sellers based on each company’s achievement of annual earnings targets in certain years and other events considered in certain transaction documents. The initial fair values of the contingent consideration was calculated through the use of either Monte Carlo simulation or modified Black-Scholes analyses based on earnings projections for the respective earn-out periods, corresponding earnings thresholds, and approximate timing of payments as outlined in the purchase agreements. The analyses utilized the following assumptions: (i) expected term; (ii) risk-adjusted net sales or earnings; (iii) risk-free interest rate; and (iv) expected volatility of earnings. Estimated payments, as determined through the respective models, were further discounted by a credit spread assumption to account for credit risk. The contingent consideration is revalued to fair value each period, and any increase or decrease is recorded in operating income (loss). The fair value of the contingent consideration may be impacted by certain unobservable inputs, most significantly with regard to discount rates, expected volatility and historical and projected performance. Significant changes to these inputs in isolation could result in a significantly different fair value measurement. The carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair value because of the short-term nature of these instruments. The Company measures certain assets at fair value on a non-recurring basis, generally annually or when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. These assets include goodwill and other intangible assets. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Temporary Equity The Class C exchangeable shares in the capital stock of Questica Exchangeco is convertible into the Company’s common stock and/or redeemable at any time at the option of the holder or the Company in the events not controlled by the Company. The Company has classified the Class C exchangeable shares in the capital stock of Questica Exchangeco as temporary equity in accordance with ASC 480 - "Distinguishing Liabilities from Equity." Foreign Currency Translation and Transactions The assets, liabilities and results of operations of certain consolidated entities are measured using their functional currency which is the currency of the primary foreign economic environment in which they operate. Upon consolidating these entities with the Company, their assets and liabilities are translated to U.S. dollars at currency exchange rates as of the condensed consolidated balance sheet date and their revenues and expenses are translated at the weighted average currency exchange rates during the applicable reporting periods. Translation adjustments resulting from the process of translating these entities’ condensed consolidated financial statements are reported in accumulated other comprehensive loss in the condensed consolidated balance sheets and total other comprehensive loss on the condensed consolidated statements of operations. Revenue Recognition The Company adopted the Financial Accounting Standards Board (“FASB”) new revenue recognition framework, ASC 606, Revenue from Contracts with Customers (“ASC 606”), on January 1, 2017 using the full retrospective approach. The adoption of this standard did not have a material impact on prior revenue recognition or on opening equity, as the timing and measurement of revenue recognition for the Company is materially the same under ASC 606 as it was under the prior relevant guidance. With the adoption of Topic 606, revenues are recognized upon transfer of control of promised products and services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. If the consideration promised in a contract includes a variable amount, the Company includes an estimate of the amount it expects to receive for the total transaction price if it is probable that a significant reversal of cumulative revenues recognized will not occur. The Company determines the amount of revenues to be recognized through application of the following steps: • Identification of the contract, or contracts with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenues when or as the Company satisfies the performance obligations. For contracts where the period between when the Company transfers a promised service to the customer and when the customer pays is one year or less, the Company has elected the practical expedient to not adjust the promised amount of consideration for the effects of a significant financing component. The Company has made a policy election to exclude from the measurement of the transaction price all taxes assessed by a government authority that are both imposed on and concurrent with a specific revenue producing transaction and collected by the Company from a customer. Such taxes may include but are not limited to sales, use, value added and certain excise taxes. Disaggregation of Revenues (Amounts in thousands) Successor Predecessor February 19, 2019 through March 31, 2019 January 1, 2019 through February 18, 2019 January 1, 2018 through March 31, 2018 Subscription, support and maintenance $ 2,018 $ 3,253 $ 4,376 Professional services 721 1,269 1,783 License 295 383 526 Asset sales - 23 105 Total revenues $ 3,034 $ 4,928 $ 6,790 Revenues Subscription, support and maintenance Our contracts may include variable consideration in the form of usage fees, which are constrained and included in the transaction price in the period in which the usage occurs and the fee is known. Subscription, support and maintenance revenues also includes kiosk rentals and on-premise support or maintenance pertaining to license sales. Revenues from kiosk rentals and on-premise support are recognized on a straight-line basis over the support period. Revenue from subscription, support and maintenance comprised approximately 66% of total revenues for the 2019 Successor Period. Professional services License . Asset sales. Contract Liabilities Contract liabilities primarily consist of amounts that have been billed to or received from customers in advance of revenue recognition and prepayments received from customers in advance for subscription services to the Company’s SaaS offerings and related implementation and training. The Company recognizes contract liabilities as revenues when the services are performed and the corresponding revenue recognition criteria are met. The Company receives payments both upfront and over time as services are performed. Customer prepayments are generally applied against invoices issued to customers when services are performed and billed. Contract liabilities are reduced as services are provided and the revenue recognition criteria are met. Contract liabilities that are expected to be recognized as revenues during the succeeding twelve-month period are recorded in current liabilities as contract liabilities, and the remaining portion is recorded in long-term liabilities as contract liabilities, non-current. Revenues of approximately $1.7 million, $2.2 million and $3.9 million were recognized for the Successor Period, the 2019 Predecessor Period, and three months ended March 31, 2018, respectively, that was included in the contract liabilities balances at the beginning of the respective periods. Cost of revenues Cost of revenues primarily consists of salaries and benefits of personnel relating to our hosting operations and support, implementation, and grants research. Cost of revenues includes data center costs including depreciation of the Company’s data center assets, third-party licensing costs, consulting fees, and the amortization of acquired technology from recent acquisitions. Stock Based Compensation The Company expenses stock-based compensation over the requisite service period based on the estimated grant-date fair value of the awards. Stock-based awards with graded-vesting schedules are recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award. The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model and the assumptions used in calculating the fair value of stock-based awards represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment. Expected Term Expected Volatility Risk-Free Interest Rate Expected Dividend Following are the assumptions used for the stock option grant on February 19, 2019: Exercise price $ 1.82 Expected term (years) 5.1 Expected stock price volatility 74 % Risk-free rate of interest 2 % In accordance with ASU No. 2016-09, Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting, . Net Loss per Share Net loss per common share is computed by dividing net income by the weighted-average number of ordinary shares outstanding during the period. Diluted net income per common share is computed similar to basic net income per common share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue Common Stock were exercised or converted into Common Stock. Due to the net loss for the Successor Period, diluted and basic loss per share are the same. Securities that could potentially dilute loss per share in the future that were not included in the computation of diluted loss per share at March 31, 2019 are as follows: Warrants to purchase common stock 27,093,334 Options to purchase common stock 399,803 Total 27,493,137 Income Taxes Deferred income taxes are provided for the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and operating loss carryforwards and credits using enacted tax rates expected to be in effect in the years in which the differences are expected to reverse. The Company assesses the likelihood that deferred tax assets will be realized and recognizes a valuation allowance if it is more likely than not that some portion of the deferred tax assets will not be realized. This assessment requires judgment as to the likelihood and amounts of future taxable income by tax jurisdiction. To date, the Company has provided a full valuation allowance against its deferred tax assets as it believes the objective and verifiable evidence of its historical pretax net losses outweighs any positive evidence of its forecasted future results. Although the Company believes that its tax estimates are reasonable, the ultimate tax determination involves significant judgment that is subject to audit by tax authorities in the ordinary course of business. The Company will continue to monitor the positive and negative evidence, and it will adjust the valuation allowance as sufficient objective positive evidence becomes available. No tax related impact was recorded in the financial statements as a result of the adoption of ASU No. 2016-09. The Company evaluates its uncertain tax positions based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is more likely than not to be realized. Potential interest and penalties associated with any uncertain tax positions are recorded as a component of income tax expense. Through March 31, 2019, the Company has not identified any material uncertain tax positions for which liabilities would be required to be recorded. As a result of the Company’s Acquisition, a temporary difference between the book fair value and tax basis for the assets acquired of $39.9 million was created, resulting in a deferred tax liability and additional goodwill. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) in order to increase transparency and comparability among organizations by, among other provisions, recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. For public companies, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 (including interim periods within those periods) using a modified retrospective approach and early adoption is permitted. In transition, entities may also elect a package of practical expedients that must be applied in its entirety to all leases commencing before the adoption date, unless the lease is modified, and permits entities to not reassess (a) the existence of a lease, (b) lease classification or (c) determination of initial direct costs, as of the adoption date, which effectively allows entities to carryforward accounting conclusions under previous U.S. GAAP. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides entities an optional transition method to apply the guidance under Topic 842 as of the adoption date, rather than as of the earliest period presented. The Company adopted Topic 842 on January 1, 2019, using the optional transition method to apply the new guidance as of January 1, 2019, rather than as of the earliest period presented, and elected the package of practical expedients described above. 3.6 3.8 Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820), – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement,” which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement amongst or hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted upon issuance of the update. The Company has not determined the impact of this guidance on its financial statements.	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 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 and 53,295,619 Class A ordinary shares subject to possible redemption at December 31, 2018 and 2017, respectively, have been excluded from the calculation of basic income per ordinary share since such shares, if redeemed, only participate in their pro rata share of the trust earnings. Net loss per share is computed by dividing net loss by the weighted-average number of ordinary shares outstanding during the period. An aggregate of 20,289,478 Class A ordinary shares subject to possible redemption at December 31, 2018 have been excluded from the calculation of basic and diluted loss per ordinary share since such ordinary Shares, if redeemed, only participate in their pro rata share of the earnings in the Trust Account. The Company has not considered the effect of the warrants sold in the initial public offering (including the consummation of the over-allotment) and private placement to purchase an aggregate of 27,093,334 shares of the Company’s Class A ordinary shares in the calculation of diluted income per share, since their inclusion would be anti-dilutive. 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 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. The Company is currently assessing the impact of the acquired companies leases post Closing. 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.

Business Combination

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	Note 4. Business Combination Successor Business Combination On February 19, 2019, the Company consummated the Business Combination, pursuant to which it 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 the Company, GTY Cayman, and GTY Technology Merger Sub, Inc. (“GTY Merger Sub”), merged with and into GTY Cayman, with GTY Cayman surviving the merger as a direct, wholly-owned subsidiary of the Company, and in connection therewith the Company changed its name from GTY Govtech, Inc. to GTY Technology Holdings Inc. This acquisition qualifies as a business combination under ASC 805. Accordingly, the Company recorded all assets acquired and liabilities assumed at their acquisition-date fair values, with any excess recognized as goodwill. Bonfire Acquisition Under the Bonfire Agreement, at Closing, the Company acquired Bonfire for aggregate consideration of approximately $48.0 million in cash and 2,156,014 shares of Company common stock (valued at $10.00 per share) and 2,161,741 shares of Bonfire Exchangeco, each of which is exchangeable for shares of Company common stock on a one-for-one basis at any time of the holder’s choosing. Of the shares issued to Bonfire Holders, 2,008,283 shares of Company common stock and 2,093,612 exchangeable shares in the capital stock of Bonfire Exchangeco are subject to transfer restrictions for one year, which such transfer restrictions may be lifted earlier if, subsequent to the Closing, (i) the last sale price of the Company common stock equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after Closing, or (ii) the Company consummates a subsequent liquidation, merger, share exchange or other similar transaction which results in all of its shareholders having the right to exchange their shares of Company common stock for cash, securities or other property. In addition, approximately $3.1 million in cash and 690,000 shares of Company common stock were deposited into escrow for a period of up to one year to cover certain indemnification obligations of the Bonfire Holders. Additionally, in accordance with the Bonfire Agreement, 1,218,937 unvested options to purchase shares of Bonfire common stock were converted into 408,667 options to purchase shares of Company common stock. CityBase Acquisition Under the CityBase Agreement, at Closing, the Company acquired CityBase for aggregate consideration of approximately $62.2 million in cash and 3,155,961 shares of Company common stock (valued at $10.00 per share). Each CityBase Holder may elect to have their shares subject to transfer restrictions for up to one year or to have their shares subject to redemption at the Company’s option for a promissory note in an amount equal to $10.00 per share redeemed, which note would bear interest at a rate of 8% per annum in the first year after issuance and 10.0% per annum thereafter (subject to an increase of 1% for each additional 6 months that has elapsed without full payment of such note(s)) (which option must be exercised within 90 days after the Closing). Prior to the consummation of the Business Combination, the CityBase Holders agreed to purchase 380,937 Class A Ordinary Shares of GTY Cayman with the proceeds they would have otherwise received from the closing of the CityBase Transaction, which resulted in an approximate $3.8 million reduction to the amount of cash payable to the CityBase Holders. In addition, approximately $2.1 million in cash and 1,000,000 shares of Company common stock were deposited into escrow for a period of up to one year to cover certain indemnification obligations of the CityBase Holders. eCivis Acquisition Under the eCivis Agreement and the eCivis Letter Agreement, at Closing, the Company acquired eCivis for aggregate consideration of approximately $14.0 million in cash and 2,883,433 shares of Company common stock (valued at $10.00 per share) (including 703,631 shares of Company common stock which are redeemable for cash at any time in the sole discretion of the Company for a price of $10.00 per share). The shares not subject to a redemption right are subject to transfer restrictions for one year, which such transfer restrictions may be lifted earlier if, subsequent to the Closing, (i) the last sale price of the Company common stock equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after Closing, or (ii) the Company consummates a subsequent liquidation, merger, share exchange or other similar transaction which results in all of its shareholders having the right to exchange their shares of Company common stock for cash, securities or other property. In addition, approximately $3.6 million in cash and 242,200 shares of Company common stock were deposited into escrow for a period of up to one year to cover certain indemnification obligations of the eCivis Holders. Open Counter Acquisition Under the Open Counter Agreement and the Open Counter Letter Agreement, at Closing, the Company acquired Open Counter for aggregate consideration of approximately $9.7 million in cash and 1,580,990 shares of Company common stock (valued at $10.00 per share) that were issued to the holders of Open Counter capital stock (the “Open Counter Holders”) (including 100,000 shares of Company common stock which are redeemable for a promissory note at the sole discretion of the Company within seven days of the Closing, which such promissory note would bear interest at a rate of 8% per annum in the first year after issuance and 10.0% per annum thereafter (subject to an increase of 1% for each additional 6 months that has elapsed without full payment of such note(s))). The shares not subject to a redemption right are subject to transfer restrictions for one year, which such transfer restrictions may be lifted earlier if, subsequent to the Closing, (i) the last sale price of the Company common stock equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after Closing, or (ii) the Company consummates a subsequent liquidation, merger, share exchange or other similar transaction which results in all of its shareholders having the right to exchange their shares of Company common stock for cash, securities or other property. In addition, approximately $1.3 million in cash and 164,554 shares of Company common stock were deposited into escrow for a period of one year to cover certain indemnification obligations of the Open Counter Holders.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	Note 6. Related Party Transactions Convertible Note On August 8, 2018, GTY Cayman issued the Convertible Note to the Sponsor, pursuant to which GTY Cayman was able to borrow up to $1 million from the Sponsor from time to time. The Convertible Note does not bear interest and the Sponsor agreed to waive all unpaid principal under the Convertible Note until the earlier of May 1, 2019 and the consummation of the business combination. The Sponsor has the option to convert any amounts outstanding under the Convertible Note, up to $1 million in the aggregate, into warrants at a conversion price of $1.50 per warrant. The terms of such warrants will be identical to the private placement warrants. During the quarter ended March 31, 2019, GTY drew down $400,000 on the Convertible Note, resulting in $1,000,000 principal amount outstanding as of March 31, 2019. Agreements and Arrangements with Certain Institutional Investors On February 13, 2019, GTY Cayman, 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 1,500,000 500,000 $10.29 $250,000, 1,000,000 $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, $ 4.0 million for losses incurred upon the sale of such shares and in turn the Company reduced its convertible note liability for $1.0	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.

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.

Commitments Disclosure [Text Block]	Note 9. Commitments and Contingencies Successor Legal Proceedings From time to time, the Companies may become involved in legal proceedings arising in the ordinary course of its business. The Companies are not presently a party to any legal proceedings that, if determined adversely to the Companies, would have a material adverse effect on the Companies. Indemnification In the ordinary course of business, the Company may provide indemnification of varying scope and terms to customers, vendors, investors, directors and officers with respect to certain matters, including, but not limited to, losses arising out of our breach of such agreements, services to be provided by the Company, or from intellectual property infringement claims made by third parties. These indemnification provisions may survive termination of the underlying agreement and the maximum potential amount of future payments the Company could be required to make under these indemnification provisions may not be subject to maximum loss clauses. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is indeterminable. The Company has never paid a material claim, nor have it been sued in connection with these indemnification arrangements. As of March 31, 2019, and December 31, 2018, the Company has not accrued a liability for these indemnification arrangements because the likelihood of incurring a payment obligation, if any, in connection with these indemnification arrangements is not probable or reasonably estimable.

Stockholders' Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	Note 10 . Shareholders’ Equity Initial Public Offering Redemption Shares 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 were entitled to redeem their public shares for a pro rata portion of the amount then in the Trust Account. public shares were 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.” 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. The remaining shares 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 Cayman issued to the Subscribed Investors an aggregate of 12,863,098 Class A ordinary shares of GTY for $10.00 per share, for an aggregate cash purchase price of approximately $126.4 million and paid fees of $1.1 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 Cayman for cancellation at no cost to GTY 231,179 Class B (founder) shares, which have been retroactively adjusted in the accompanying statement of stockholders equity, 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). GTY Merger Share Exchange In connection with the GTY Merger, all of the issued and outstanding shares of GTY Cayman were exchanged for an equal number of shares of GTY common stock and immediately before the exchange, each outstanding unit was separated into its component Class A ordinary share and warrant. Upon the exchange 22,978,520 Class A and 13,568,821 Class B shares of GTY Cayman were exchanged for 36,547,341 shares of Common Stock of GTY. Shares issued in the Acquisition As part of the consideration for the Acquisition, the Company issued (a) 11,973,154 shares of Series A common stock, of which 3,937,907 are redeemable at the option of the Company (the “Acquisition Redemption Shares”), (b) 2.6 million Class A and 0.5 million Class C shares of Questica Exchangeco (the “Questica Shares”) and 2,161,741 shares of Bonfire Exchangeco shares (collectively, the “Exchange Shares”) that are exchangeable into an equal number of Common Stock. The Exchange Shares are recorded as common shares of the Company. The Company also issued 1,000,000 Class B shares of Questica Shares which are not exchangeable for Common Stock and thus have no value. The 500,000 Class C shares of the Questica shares are redeemable at the option of the shareholder and thus are included in temporary equity in the condensed consolidated balance sheet as of March 31, 2019. The shares issued as consideration in the Acquisition were valued at $10 per share in the accompanying condensed consolidated financial statements. In March 2019, 500,000 of the Acquisition Redemption Shares were redeemed by the Company at a price of $10 per share. Common Stock 400,000,000 $0.0001 48,420,495 Preferred Shares – GTY was authorized to issue 1,000,000 preferred shares with a par value of $0.0001 per share. As of March 31, 2019 , there were no preferred shares issued or outstanding. Warrants At March 31, 2019 , there were a total of 27,093,334 warrants outstanding. The warrants were originally sold as part of the units offered in the IPO. Each warrant entitles the holder thereof to purchase one share of Common Stock at a price of $ 11.50 per share, subject to adjustments. The warrants may be exercised only for a whole number of shares of Common Stock. No fractional shares will be issued upon exercise of the warrants. The Company may call the warrants for redemption, in whole and not in part, at a price of $ 0.01 per warrant, upon not less than 30 days’ prior written notice of redemption to each warrant holder, if, and only if, the reported last sale price of Common Stock 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 the Company sends the notice of redemption to the warrant holders. The warrants were determined to be equity classified in accordance with ASC 815 , Derivatives and Hedging .	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.

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 - The public warrants may only be exercised for a whole number of shares. The public warrants are provided that the Company has an effective registration statement under the Securities Act covering the shares issuable upon exercise of the public warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their public warrants on a cashless basis and such cashless exercise is exempt from registration under the Securities Act). If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the sixtieth (60 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.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Certain information and disclosures normally included in condensed consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The accompanying condensed consolidated financial statements should be read in conjunction with the Company's audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 filed with the Securities and Exchange Commission (“SEC”) on March 18, 2019 and the Company’s Current Report Form 8-K/A filed with the SEC on March 18, 2019. The Acquisition was accounted for as a business combination using the acquisition method of accounting. The Company’s financial statement presentation distinguishes the results of operations into two distinct periods: (i) the period before the consummation of the Acquisition, which includes the period from January 1, 2019 to the Closing Date (the “2019 Predecessor Period”) and the three months ended March 31, 2018 (the “2018 Predecessor Period”) and (ii) the period after consummation of the Acquisition which includes the period including and after the Closing Date to March 31, 2019 (the “Successor Period”). The accompanying condensed consolidated financial statements include a black line division which indicates that the Acquired Companies and the Company’s financial information are presented on a different basis and are therefore, not comparable. Determining the fair value of certain assets and liabilities assumed is judgmental in nature and often involves the use of significant estimates and assumptions. See Note 4 – Business Combination for a discussion of the estimated fair values of assets and liabilities recorded in connection with the Acquisition. The historical financial information of GTY Cayman prior to the Acquisition is not being reflected in the Predecessor financial statements as these historical amounts have been determined not to be useful to a user of the financial statements. GTY Cayman’s operations prior to the Acquisition, other than income from the Trust Account investments and transaction expenses, were nominal. The Company believes that Predecessor activities related to investments, intangible assets, stock-based compensation, goodwill, fair value measurements and notes payable were either quantitatively or qualitatively immaterial. Therefore, the Company did not disclose these Predecessor activities in the following unaudited footnotes.	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.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The Successor Period condensed consolidated financial statements include all accounts of the Company and its subsidiaries. The Predecessor Period condensed consolidated financial statements include all accounts of the Acquired Companies and the Acquired Companies’ subsidiaries. All material intercompany transactions and balances have been eliminated in the accompanying condensed consolidated financial statements.	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.
Segment Reporting, Policy [Policy Text Block]	Segments The Company has six operating segments. The Company’s Chief Executive Officer and Chief Financial Officer, who jointly are the Company’s chief operating decision maker, review financial information for each of the Acquired Companies, together with certain operating metrics principally to make decisions about how to allocate resources and to measure the Company’s performance. See Note 12.
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, Policy [Policy Text Block]	Cash and Cash Equivalents The Company considers all highly liquid investments with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents. Cash includes cash held in checking and savings accounts. Cash equivalents are comprised of investments in money market mutual funds. Cash and cash equivalents are recorded at cost, which approximates fair value.
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.
Trade and Other Accounts Receivable, Policy [Policy Text Block]	Accounts Receivable Accounts receivable consists of amounts due from our customers, which are primarily located throughout the United States and Canada. Accounts receivable are recorded at the invoiced amount, do not require collateral, and do not bear interest. The Company estimates its allowance for doubtful accounts by evaluating specific accounts where information indicates the Company’s customers may have an inability to meet financial obligations, such as bankruptcy and significantly aged receivables outstanding. Uncollectible receivables are written-off in the period management believes it has exhausted every opportunity to collect payment from the customer. Bad debt expense is recorded when events or circumstances indicate an additional allowance is required based on the Company’s specific identification approach. The allowance for doubtful accounts for the Successor as of March 31, 2019 and for the Predecessor as of December 31, 2018 was immaterial. Bad debt expense for the period from February 19, 2019 to March 31, 2019 (Successor), the period from January 1, 2019 to February 18, 2019 (Predecessor) and the three months ended March 31, 2018 (Predecessor) was immaterial.
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 and cash equivalents, and accounts receivable. Cash accounts in a financial institution at times may exceed the Federal depository insurance coverage of $250,000. As of March 31, 2019 and December 31, 2018, the Company had not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Additionally, all Canadian Dollars (“CDN”) institution amounts are covered by Canada Deposit Insurance Corporation, or CDIC insurance.	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 condensed 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 revenues and expenses during the reporting periods. Significant items subject to such estimates include revenue recognition, the carrying value of goodwill, the fair value of acquired intangibles, the capitalization of software development costs, and the useful lives intangible assets, stock-based compensation, contingent consideration and the valuation allowance of deferred tax assets resulting from net operating losses.	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.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equipment are recorded at cost. Maintenance and repairs are charged to expense as incurred, and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gain or loss is reflected in the condensed consolidated statement of operations in the period realized. Property, plant and equipment is depreciated using the straight-line method over 5 to 15 years. Internal-use software is amortized on a straight-line basis over its estimated useful life or 5 years. Leasehold improvements are amortized over the shorter of the useful lives or the term of the respective leases. Depreciation expense recognized by the Company for the period from February 19, 2019 to March 31, 2019 (Successor) was $0.1 million. Depreciation expense recognized by the Predecessor for the period from January 1, 2019 through February 18, 2018 and the three months ended March 31, 2018 was $0.2 million and $0.2 million, respectively.
Capitalization of Internal Costs, Policy [Policy Text Block]	Capitalized Software Costs The Company capitalizes costs incurred during the application development stage related to the development of internal-use software and enterprise cloud computing services. Costs related to preliminary project activities and post-implementation activities are expensed as incurred.
Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]	Intangible Assets (Successor) Intangible assets consist of acquired customer relationships, acquired developed technology, trade name and non-compete agreements which were acquired as part of the Acquisition. The Company determines the appropriate useful life of its intangible assets by performing an analysis of expected cash flows of the acquired assets. Intangible assets are amortized over their estimated useful lives using the straight-line method, which approximates the pattern in which the economic benefits are consumed.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill (Successor) Goodwill represents the excess of the purchase price of an entity over the estimated fair value of the assets acquired and liabilities assumed, and it is presented as Goodwill in the accompanying condensed consolidated balance sheet of the Successor. Under ASC 350, Intangibles – Goodwill and Other
Business Combinations Policy [Policy Text Block]	Business Combinations (Successor) The Company accounts for business acquisitions using the acquisition method of accounting based on Accounting Standards Codification (“ASC”) 805 — Business Combinations, which requires recognition and measurement of all identifiable assets acquired and liabilities assumed at their fair value as of the date control is obtained. The Company determines the fair value of assets acquired and liabilities assumed based upon its best estimates of the acquisition-date fair value of assets acquired and liabilities assumed in the acquisition. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired. Subsequent adjustments to fair value of any contingent consideration are recorded to the Company’s condensed consolidated statements of operations.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of long-lived assets The Company reviews long-lived assets, including property and equipment and intangible assets and goodwill for impairment whenever events or changes in business circumstances indicate that the carrying amount of an asset may not be fully recoverable. An impairment loss is recognized when the asset’s carrying value exceeds the total undiscounted cash flows expected from its use and eventual disposition. The amount of the impairment loss is determined as the excess of the carrying value of the asset over its fair value.
Lessee, Leases [Policy Text Block]	Leases Effective January 1, 2019, the Company accounts for its leases under ASC 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases, and are recorded on the condensed consolidated balance sheet as both a right of use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right of use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right of use asset result in straight-line rent expense over the lease term. Variable lease expenses are recorded when incurred. In calculating the right of use asset and lease liability, the Company elects to combine lease and non-lease components. The Company excludes short-term leases having initial terms of 12 months or less from the new guidance as an accounting policy election, and recognizes rent expense on a straight-line basis over the lease term. The Company continues to account for leases prior to January 1, 2019 under ASC Topic 840.
Fair Value Measurement, Policy [Policy Text Block]	Fair Value (Successor) The fair value of an asset or liability is the price that would be received to sell an asset or transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value and defines three levels of inputs that may be used to measure fair value . • Level 1 — uses quoted prices in active markets for identical assets or liabilities. • Level 2 — uses observable inputs other than quoted prices in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 — uses one or more significant inputs that are unobservable and supported by little or no market activity, and that reflect the use of significant management judgment. The Company’s only material financial instruments carried at fair value as of March 31, 2019, with changes in fair value flowing through current earnings, consist of contingent consideration liabilities recorded in conjunction with business combinations, as follows (in thousands): Fair Value Measurement at Reporting Date Using Balance as of March 31, 2019 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Contingent consideration – current $ 11,515 $ - $ - $ 11,515 Contingent consideration – long term 56,333 - - 56,333 Total liabilities measured at fair value $ 67,848 $ - $ - $ 67,848 There were no transfers made among the three levels in the fair value hierarchy during the three months ended March 31, 2019. The following table presents additional information about Level 3 liabilities measured at fair value. Both observable and unobservable inputs may be used to determine the fair value of positions that the Company has classified within the Level 3 category. As a result, the unrealized gains and losses for liabilities within the Level 3 category may include changes in fair value that were attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long-dated volatilities) inputs. Changes in Level 3 liabilities measured at fair value from February 18, 2019 to March 31, 2019 (in thousands): Contingent consideration - February 18, 2019 $ 2,031 Fair value of contingent consideration – Bonfire 325 Fair value of contingent consideration – CityBase 48,410 Fair value of contingent consideration – eCivis 5,859 Fair value of contingent consideration - Questica 9,311 Fair value of contingent consideration – Sherpa 1,898 Change due to fluctuation in foreign currency 14 Contingent consideration - March 31, 2019 $ 67,848 There was no a material change in fair value of contingent consideration from the Acquired Companies acquisitions through March 31, 2019. The fair value of the Company’s contingent consideration liabilities recorded as part of the acquisitions has been classified within Level 3 in the fair value hierarchy. The contingent consideration represents the estimated fair value of future payments due to the sellers based on each company’s achievement of annual earnings targets in certain years and other events considered in certain transaction documents. The initial fair values of the contingent consideration was calculated through the use of either Monte Carlo simulation or modified Black-Scholes analyses based on earnings projections for the respective earn-out periods, corresponding earnings thresholds, and approximate timing of payments as outlined in the purchase agreements. The analyses utilized the following assumptions: (i) expected term; (ii) risk-adjusted net sales or earnings; (iii) risk-free interest rate; and (iv) expected volatility of earnings. Estimated payments, as determined through the respective models, were further discounted by a credit spread assumption to account for credit risk. The contingent consideration is revalued to fair value each period, and any increase or decrease is recorded in operating income (loss). The fair value of the contingent consideration may be impacted by certain unobservable inputs, most significantly with regard to discount rates, expected volatility and historical and projected performance. Significant changes to these inputs in isolation could result in a significantly different fair value measurement. The carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair value because of the short-term nature of these instruments. The Company measures certain assets at fair value on a non-recurring basis, generally annually or when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. These assets include goodwill and other intangible assets. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.	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.

Stockholders' Equity, Policy [Policy Text Block]	Temporary Equity The Class C exchangeable shares in the capital stock of Questica Exchangeco is convertible into the Company’s common stock and/or redeemable at any time at the option of the holder or the Company in the events not controlled by the Company. The Company has classified the Class C exchangeable shares in the capital stock of Questica Exchangeco as temporary equity in accordance with ASC 480 - "Distinguishing Liabilities from Equity."
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translation and Transactions The assets, liabilities and results of operations of certain consolidated entities are measured using their functional currency which is the currency of the primary foreign economic environment in which they operate. Upon consolidating these entities with the Company, their assets and liabilities are translated to U.S. dollars at currency exchange rates as of the condensed consolidated balance sheet date and their revenues and expenses are translated at the weighted average currency exchange rates during the applicable reporting periods. Translation adjustments resulting from the process of translating these entities’ condensed consolidated financial statements are reported in accumulated other comprehensive loss in the condensed consolidated balance sheets and total other comprehensive loss on the condensed consolidated statements of operations.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition The Company adopted the Financial Accounting Standards Board (“FASB”) new revenue recognition framework, ASC 606, Revenue from Contracts with Customers (“ASC 606”), on January 1, 2017 using the full retrospective approach. The adoption of this standard did not have a material impact on prior revenue recognition or on opening equity, as the timing and measurement of revenue recognition for the Company is materially the same under ASC 606 as it was under the prior relevant guidance. With the adoption of Topic 606, revenues are recognized upon transfer of control of promised products and services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. If the consideration promised in a contract includes a variable amount, the Company includes an estimate of the amount it expects to receive for the total transaction price if it is probable that a significant reversal of cumulative revenues recognized will not occur. The Company determines the amount of revenues to be recognized through application of the following steps: • Identification of the contract, or contracts with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenues when or as the Company satisfies the performance obligations. For contracts where the period between when the Company transfers a promised service to the customer and when the customer pays is one year or less, the Company has elected the practical expedient to not adjust the promised amount of consideration for the effects of a significant financing component. The Company has made a policy election to exclude from the measurement of the transaction price all taxes assessed by a government authority that are both imposed on and concurrent with a specific revenue producing transaction and collected by the Company from a customer. Such taxes may include but are not limited to sales, use, value added and certain excise taxes.
Disaggregation Of Revenue [Policy Text Block]	Disaggregation of Revenues (Amounts in thousands) Successor Predecessor February 19, 2019 through March 31, 2019 January 1, 2019 through February 18, 2019 January 1, 2018 through March 31, 2018 Subscription, support and maintenance $ 2,018 $ 3,253 $ 4,376 Professional services 721 1,269 1,783 License 295 383 526 Asset sales - 23 105 Total revenues $ 3,034 $ 4,928 $ 6,790 Revenues Subscription, support and maintenance Our contracts may include variable consideration in the form of usage fees, which are constrained and included in the transaction price in the period in which the usage occurs and the fee is known. Subscription, support and maintenance revenues also includes kiosk rentals and on-premise support or maintenance pertaining to license sales. Revenues from kiosk rentals and on-premise support are recognized on a straight-line basis over the support period. Revenue from subscription, support and maintenance comprised approximately 66% of total revenues for the 2019 Successor Period. Professional services License . Asset sales.
Revenue from Contract with Customer [Policy Text Block]	Contract Liabilities Contract liabilities primarily consist of amounts that have been billed to or received from customers in advance of revenue recognition and prepayments received from customers in advance for subscription services to the Company’s SaaS offerings and related implementation and training. The Company recognizes contract liabilities as revenues when the services are performed and the corresponding revenue recognition criteria are met. The Company receives payments both upfront and over time as services are performed. Customer prepayments are generally applied against invoices issued to customers when services are performed and billed. Contract liabilities are reduced as services are provided and the revenue recognition criteria are met. Contract liabilities that are expected to be recognized as revenues during the succeeding twelve-month period are recorded in current liabilities as contract liabilities, and the remaining portion is recorded in long-term liabilities as contract liabilities, non-current. Revenues of approximately $1.7 million, $2.2 million and $3.9 million were recognized for the Successor Period, the 2019 Predecessor Period, and three months ended March 31, 2018, respectively, that was included in the contract liabilities balances at the beginning of the respective periods.
Cost of Sales, Policy [Policy Text Block]	Cost of revenues Cost of revenues primarily consists of salaries and benefits of personnel relating to our hosting operations and support, implementation, and grants research. Cost of revenues includes data center costs including depreciation of the Company’s data center assets, third-party licensing costs, consulting fees, and the amortization of acquired technology from recent acquisitions.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock Based Compensation The Company expenses stock-based compensation over the requisite service period based on the estimated grant-date fair value of the awards. Stock-based awards with graded-vesting schedules are recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award. The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model and the assumptions used in calculating the fair value of stock-based awards represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment. Expected Term Expected Volatility Risk-Free Interest Rate Expected Dividend Following are the assumptions used for the stock option grant on February 19, 2019: Exercise price $ 1.82 Expected term (years) 5.1 Expected stock price volatility 74 % Risk-free rate of interest 2 % In accordance with ASU No. 2016-09, Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting, .
Earnings Per Share, Policy [Policy Text Block]	Net Loss per Share Net loss per common share is computed by dividing net income by the weighted-average number of ordinary shares outstanding during the period. Diluted net income per common share is computed similar to basic net income per common share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue Common Stock were exercised or converted into Common Stock. Due to the net loss for the Successor Period, diluted and basic loss per share are the same. Securities that could potentially dilute loss per share in the future that were not included in the computation of diluted loss per share at March 31, 2019 are as follows: Warrants to purchase common stock 27,093,334 Options to purchase common stock 399,803 Total 27,493,137	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 and 53,295,619 Class A ordinary shares subject to possible redemption at December 31, 2018 and 2017, respectively, have been excluded from the calculation of basic income per ordinary share since such shares, if redeemed, only participate in their pro rata share of the trust earnings. Net loss per share is computed by dividing net loss by the weighted-average number of ordinary shares outstanding during the period. An aggregate of 20,289,478 Class A ordinary shares subject to possible redemption at December 31, 2018 have been excluded from the calculation of basic and diluted loss per ordinary share since such ordinary Shares, if redeemed, only participate in their pro rata share of the earnings in the Trust Account. The Company has not considered the effect of the warrants sold in the initial public offering (including the consummation of the over-allotment) and private placement to purchase an aggregate of 27,093,334 shares of the Company’s Class A ordinary shares in the calculation of diluted income per share, since their inclusion would be anti-dilutive.
Income Tax, Policy [Policy Text Block]	Income Taxes Deferred income taxes are provided for the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and operating loss carryforwards and credits using enacted tax rates expected to be in effect in the years in which the differences are expected to reverse. The Company assesses the likelihood that deferred tax assets will be realized and recognizes a valuation allowance if it is more likely than not that some portion of the deferred tax assets will not be realized. This assessment requires judgment as to the likelihood and amounts of future taxable income by tax jurisdiction. To date, the Company has provided a full valuation allowance against its deferred tax assets as it believes the objective and verifiable evidence of its historical pretax net losses outweighs any positive evidence of its forecasted future results. Although the Company believes that its tax estimates are reasonable, the ultimate tax determination involves significant judgment that is subject to audit by tax authorities in the ordinary course of business. The Company will continue to monitor the positive and negative evidence, and it will adjust the valuation allowance as sufficient objective positive evidence becomes available. No tax related impact was recorded in the financial statements as a result of the adoption of ASU No. 2016-09. The Company evaluates its uncertain tax positions based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is more likely than not to be realized. Potential interest and penalties associated with any uncertain tax positions are recorded as a component of income tax expense. Through March 31, 2019, the Company has not identified any material uncertain tax positions for which liabilities would be required to be recorded. As a result of the Company’s Acquisition, a temporary difference between the book fair value and tax basis for the assets acquired of $39.9 million was created, resulting in a deferred tax liability and additional goodwill.	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.
Recently Issued Accounting Pronouncements [Policy Text Block]	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) in order to increase transparency and comparability among organizations by, among other provisions, recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. For public companies, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 (including interim periods within those periods) using a modified retrospective approach and early adoption is permitted. In transition, entities may also elect a package of practical expedients that must be applied in its entirety to all leases commencing before the adoption date, unless the lease is modified, and permits entities to not reassess (a) the existence of a lease, (b) lease classification or (c) determination of initial direct costs, as of the adoption date, which effectively allows entities to carryforward accounting conclusions under previous U.S. GAAP. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides entities an optional transition method to apply the guidance under Topic 842 as of the adoption date, rather than as of the earliest period presented. The Company adopted Topic 842 on January 1, 2019, using the optional transition method to apply the new guidance as of January 1, 2019, rather than as of the earliest period presented, and elected the package of practical expedients described above. 3.6 3.8 Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820), – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement,” which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement amongst or hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted upon issuance of the update. The Company has not determined the impact of this guidance on its financial statements.
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
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. The Company is currently assessing the impact of the acquired companies leases post Closing. 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.

Dividend Distribution Terms, Description				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.
