Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation We prepared the accompanying condensed consolidated financial statements following the requirements of the Securities and Exchange Commission (“SEC”) and accounting principles generally accepted in the United States, or GAAP, for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted for interim periods. Balance sheet amounts are as of June 30, 2019 , and December 31, 2018 , and operating result amounts are for the three and six months ended June 30, 2019 , and 2018 , respectively, and include all normal and recurring adjustments that we considered necessary for the fair summarized presentation of our financial position and operating results. As these are condensed financial statements, one should also read the financial statements and notes included in our latest Form 10-K for the year ended December 31, 2018 . Revenues, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be the same as those for the full year. Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions, and other events and circumstances from non-owner sources and includes all components of net income (loss) and other comprehensive income (loss). We had no items of other comprehensive income (loss) for the three and six months ended June 30, 2019 , and 2018 .

Accounting Policies [Abstract]
Accounting Standards and Significant Accounting Policies	Accounting Standards and Significant Accounting Policies SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Except for the accounting policies for leases recognition that were adjusted as a result of adopting ASU No. 2016-02, Leases (" Topic 842 ") , there have been no changes to our significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC on February 20, 2019, that have had a material impact on our condensed consolidated financial statements and related notes. USE OF ESTIMATES The preparation of our financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires us 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include revenue recognition, determining the nature and timing of satisfaction of performance obligations, determining the standalone selling price ("SSP") of performance obligations, variable consideration, and other obligations such as returns and refunds; loss contingencies; the estimated useful life of deferred commissions; the carrying amount and estimated useful lives of intangible assets; the carrying amount of operating lease right-of-use assets and operating lease liabilities; determining share-based compensation expense; the valuation allowance for receivables; and determining the potential outcome of future tax consequences of events that have been recognized on our consolidated financial statements or tax returns. Actual results could differ from estimates. REVENUE RECOGNITION Nature of Products and Services: We earn revenue from software licenses, royalties, subscription-based services, software services, post-contract customer support (“PCS” or “maintenance”), hardware, and appraisal services. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We determine revenue recognition through 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 • Recognition of revenue when, or as, we satisfy a performance obligation Most of our software arrangements with customers contain multiple performance obligations that range from software licenses, installation, training, and consulting to software modification and customization to meet specific customer needs (services), hosting, and PCS. For these contracts, we account for individual performance obligations separately when they are distinct. We evaluate whether separate performance obligations can be distinct or should be accounted for as one performance obligation. Arrangements that include software services, such as training or installation, are evaluated to determine whether the customer can benefit from the services either on their own or together with other resources readily available to the customer and whether the services are separately identifiable from other promises in the contract. The transaction price is allocated to the distinct performance obligations on a relative SSP basis. We determine the SSP based on our overall pricing objectives, taking into consideration market conditions and other factors, including the value of our contracts, the applications sold, customer demographics, and the number and types of users within our contracts. Revenue is recognized net of allowances for sales adjustments and any taxes collected from customers, which are subsequently remitted to governmental authorities. Significant Judgments: Our contracts with customers often include multiple performance obligations to a customer. When a software arrangement (license or subscription) includes both software licenses and software services, judgment is required to determine whether the software license is considered distinct and accounted for separately, or not distinct and accounted for together with the software services and recognized over time. The transaction price is allocated to the separate performance obligations on a relative SSP basis. We determine the SSP based on our overall pricing objectives, taking into consideration market conditions and other factors, including the value of our contracts, the applications sold, customer demographics, and the number and types of users within our contracts. We use a range of amounts to estimate SSP when we sell each of the products and services separately and need to determine whether there is a discount to be allocated based on the relative SSP of the various products and services. In instances where SSP is not directly observable, such as when we do not sell the product or service separately, we determine SSP using the expected cost-plus margin approach. For arrangements that involve significant production, modification or customization of the software, or where software services otherwise cannot be considered distinct, we recognize revenue as control is transferred to the customer over time using progress-to-completion methods. Depending on the contract, we measure progress-to-completion primarily using labor hours incurred, or value added. The progress-to-completion method generally results in the recognition of reasonably consistent profit margins over the life of a contract because we can provide reasonably dependable estimates of contract billings and contract costs. We use the level of profit margin that is most likely to occur on a contract. If the most likely profit margin cannot be precisely determined, the lowest probable level of profit margin in the range of estimates is used until the results can be estimated more precisely. These arrangements are often implemented over an extended time period and occasionally require us to revise total cost estimates. Amounts recognized in revenue are calculated using the progress-to-completion measurement after giving effect to any changes in our cost estimates. Changes to total estimated contract costs, if any, are recorded in the period they are determined. Estimated losses on uncompleted contracts are recorded in the period in which we first determine that a loss is apparent. Typically, the structure of our arrangements does not give rise to variable consideration. However, in those instances whereby variable consideration exists, we include in our estimates additional revenue for variable consideration when we believe we have an enforceable right, the amount can be estimated reliably and its realization is probable. Refer to Note 13 - Disaggregation of Revenue for further information, including the economic factors that affect the nature, amount, timing, and uncertainty of revenue and cash flows of our various revenue categories. Contract Balances: Accounts receivable and allowance for doubtful accounts Timing of revenue recognition may differ from the timing of invoicing to customers. We record an unbilled receivable when revenue is recognized prior to invoicing, or deferred revenue when revenue is recognized subsequent to invoicing. For multi-year agreements, we generally invoice customers annually at the beginning of each annual coverage period. We record an unbilled receivable related to revenue recognized for on-premises licenses as we have an unconditional right to invoice and receive payment in the future related to those licenses. At June 30, 2019 , and December 31, 2018 , total current and long-term accounts receivable, net of allowance for doubtful accounts, was $401.9 million and $314.9 million , respectively. We have recorded unbilled receivables of $118.3 million and $104.2 million at June 30, 2019 , and December 31, 2018 , respectively. Included in unbilled receivables are retention receivables of $12.9 million and $12.2 million at June 30, 2019 , and December 31, 2018 , respectively, which become payable upon the completion of the contract or completion of our fieldwork and formal hearings. Unbilled receivables expected to be collected within one year have been included with accounts receivable, current portion in the accompanying condensed consolidated balance sheets. Unbilled receivables and retention receivables expected to be collected past one year have been included with accounts receivable, long-term portion in the accompanying condensed consolidated balance sheets. We maintain allowances for doubtful accounts, which are provided at the time the revenue is recognized. Since most of our customers are domestic governmental entities, we rarely incur a loss resulting from the inability of a customer to make required payments. Events or changes in circumstances that indicate the carrying amount for the allowances for doubtful accounts may require revision, include, but are not limited to, deterioration of a customer’s financial condition, failure to manage our customer’s expectations regarding the scope of the services to be delivered, and defects or errors in new versions or enhancements of our software products. The following table summarizes the changes in the allowance for doubtful accounts (in thousands): Six months ended June 30, 2019 Balance, beginning of period December 31, 2018 $ 4,647 Provisions for losses - accounts receivable 1,664 Collection of accounts previously written off — Deductions for accounts charged off or credits issued (2,465 ) Balance, end of period $ 3,846 LEASES We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities on our consolidated balance sheets. We currently do not have any finance lease arrangements. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date of the lease in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components, which are generally accounted as a single lease component. RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS Leases. We adopted Topic 842 using the transition method that allows us to initially apply the guidance at the adoption date of January 1, 2019, and recognized a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. We used the package of practical expedients that allows us to not reassess: (1) lease classification for any expired or existing leases and (2) initial direct costs for any expired or existing leases. We did not elect to use the hindsight application for evaluating the life of the lease arrangement. The impact of adoption is reflected in the financial information herein. For additional details, see Note 10 to our condensed consolidated financial statements. The impact of Topic 842 on our consolidated balance sheet beginning January 1, 2019, included the recognition of ROU assets and lease liabilities for operating leases, while our accounting for finance leases remained substantially unchanged. We had no finance leases prior to the adoption of Topic 842 and currently do not have any. Amounts recognized at January 1, 2019, for operating leases were as follow (in thousands): Operating lease right-of-use assets $ 15,633 Operating lease liabilities (4,344 ) Operating lease liabilities, long-term (12,405 ) Retained earnings $ (1,116 ) No impact was recorded to the statement of income for the adoption of Topic 842. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, (“ASU 2016-13”). ASU 2016-13 changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, held-to-maturity debt securities and loans, and requires entities to use a new forward-looking expected loss model that will result in the earlier recognition of allowance for losses. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for a fiscal year beginning after December 15, 2018, including interim periods within that fiscal year. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We are currently assessing the potential impact of ASU 2016-13 on our consolidated financial statements and results of operations.

Business Combinations [Abstract]
Acquisitions	Acquisitions On February 28, 2019, we acquired all of the capital stock of MP Holdings Parent, Inc. dba MicroPact ("MicroPact"), a leading provider of commercial off-the-shelf (COTS) solutions, including entellitrak®, a low-code application development platform for case management and business process management used extensively in the public sector. The total purchase price, net of cash acquired of $2.0 million , was approximately $204.2 million consisting of $197.5 million paid in cash, accrued contingent consideration of $7.0 million contingent upon the achievement of certain financial performance objectives, and $1.7 million accrued for certain holdbacks, subject to certain post-closing adjustments. We have performed a preliminary valuation analysis of the fair market value of MicroPact’s assets and liabilities. The following table summarizes the preliminary allocation of the purchase price as of the acquisition date: (In thousands) Cash $ 1,983 Accounts receivable 11,852 Other current assets 8,979 Other noncurrent assets 10,417 Identifiable intangible assets 118,843 Goodwill 83,065 Accounts payable (602 ) Accrued expenses (2,432 ) Other noncurrent liabilities (8,879 ) Deferred revenue (11,312 ) Deferred tax liabilities, net (5,766 ) Total consideration $ 206,148 In connection with this transaction, we acquired total tangible assets of $33.2 million and assumed liabilities of approximately $23.2 million . We recorded goodwill of $83.1 million , none of which is expected to be deductible for tax purposes, and other identifiable intangible assets of approximately $118.8 million . The $118.8 million of intangible assets are attributable to customer relationships, acquired software, trade name and favorable fair value of an operating lease and will be amortized over a weighted average period of approximately 10 years . We recorded deferred tax liabilities of $5.8 million related to estimated fair value allocations. The acquisition of MicroPact augments our product solutions, positions us in new practice areas such as health and human services, and presents opportunities to expand our business across new and complementary markets. We intend to expand our total addressable market through MicroPact's strong presence in the federal market. Therefore, the goodwill of $83.1 million arising from this acquisition is primarily attributed to our ability to generate increased revenues, earnings and cash flow by expanding our addressable market and client base. In the six months ended June 30, 2019 , we recorded adjustments to the preliminary opening balance sheet attributed to an increase in deferred revenue and related deferred taxes resulting in a net increase to goodwill of approximately $1.0 million . The following unaudited pro forma consolidated operating results information has been prepared as if the MicroPact acquisition had occurred at January 1, 2018, after giving effect to certain adjustments, including amortization of intangibles, interest, transaction costs and tax effects. Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Revenues $ 275,124 $ 254,471 $ 533,988 $ 493,004 Net income 31,999 39,720 59,166 76,792 Basic earnings per share 0.83 1.03 1.54 2.00 Diluted earnings per share $ 0.80 $ 0.99 $ 1.49 $ 1.91 The pro forma information above does not include acquisitions that are not considered material to our results of operations. The pro forma information does not purport to represent what our results of operations actually would have been had such transaction occurred on the date specified or to project our results of operations for any future period. On February 1, 2019, we acquired all the assets of Civic, LLC ("MyCivic"), a company that provides software solutions to connect communities. The total purchase price was $3.7 million in cash. As of June 30, 2019 , the purchase price allocations for MicroPact and MyCivic are not yet complete. The preliminary estimates of fair value assumed at the acquisition date for intangible assets, deferred revenue, accrued contingent consideration, accrued holdbacks and related deferred taxes are subject to change as valuations are finalized. The operating results of MicroPact and MyCivic are included in the operating results of the Enterprise Software segment since their respective dates of acquisition. Revenues from MicroPact included in Tyler's results of operations were approximately $14.6 million and $20.1 million for the three and six months ended June 30, 2019 , respectively, and net loss was $3.2 million and $3.6 million for the three and six months ended June 30, 2019 , respectively. Revenues and operating results from MyCivic included in 2019 results were not significant. As of June 30, 2019 , we incurred fees of approximately $0.9 million for financial advisory, legal, accounting, due diligence, valuation and other various services necessary to complete these acquisitions. These fees were expensed in 2019 and are included in Selling, general and administrative expenses on the condensed consolidated statement of income. Our balance sheet as of June 30, 2019

Revenue from Contract with Customer [Abstract]
Deferred Commissions	Deferred Commissions Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions for initial contracts are deferred and then amortized commensurate with the recognition of associated revenue over a period of benefit that we have determined to be three to seven years . Deferred commissions were $27.2 million and $21.9 million as of June 30, 2019 , and December 31, 2018 , respectively. Amortization expense was $4.1 million and $7.9 million for the three and six months ended June 30, 2019 , respectively, and $3.7 million and $7.1 million for the three and six months ended June 30, 2018 , respectively. There were no indicators of impairment in relation to the costs capitalized for the periods presented. Deferred commissions have been included with prepaid expenses for the current portion and non-current other assets for the long-term portion in the accompanying condensed consolidated balance sheets. Amortization expense related to deferred commissions is included in selling, general and administrative expenses in the accompanying condensed consolidated statements of income. The tables below show disaggregation of revenue into categories that reflect how economic factors affect the nature, amount, timing, and uncertainty of revenue and cash flows.

Virtually all of our on-premises software clients contract with us for maintenance and support, which provides us with a significant source of recurring revenue. We generally provide maintenance and support for our on-premises clients under annual, or in some cases, multi-year contracts. The contract terms for subscription arrangements range from one to 10 years but are typically contracted for initial periods of three to five years , providing a significant source of recurring revenues on an annual basis. Non-recurring revenues are derived for all other revenue categories. Recurring revenues and non-recurring revenues recognized during the period are as follows (in thousands): For the three months ended June 30, 2019 Enterprise Software Appraisal and Tax Corporate Totals Recurring revenues $ 171,350 $ 8,814 $ — $ 180,164 Non-recurring revenues 72,622 16,185 6,153 94,960 Intercompany 3,660 — (3,660 ) — Total revenues $ 247,632 $ 24,999 $ 2,493 $ 275,124 For the six months ended June 30, 2019 Enterprise Software Appraisal and Tax Corporate Totals Recurring revenues $ 330,004 $ 17,587 $ — $ 347,591 Non-recurring revenues 137,790 30,659 6,150 174,599 Intercompany 7,213 — (7,213 ) — Total revenues $ 475,007 $ 48,246 $ (1,063 ) $ 522,190 For the three months ended June 30, 2018 Enterprise Software Appraisal and Tax Corporate Totals Recurring revenues $ 140,432 $ 8,653 $ — $ 149,085 Non-recurring revenues 68,717 13,646 4,612 86,975 Intercompany 3,086 — (3,086 ) — Total revenues $ 212,235 $ 22,299 $ 1,526 $ 236,060 For the six months ended June 30, 2018 Enterprise Software Appraisal and Tax Corporate Totals Recurring revenues $ 274,930 $ 17,080 $ — $ 292,010 Non-recurring revenues 133,495 26,779 4,950 165,224 Intercompany 6,322 — (6,322 ) — Total revenues $ 414,747 $ 43,859 $ (1,372 ) $ 457,234 Total deferred revenue, including long-term, by segment is as follows (in thousands): June 30, 2019 December 31, 2018 Enterprise Software $ 346,583 $ 327,521 Appraisal and Tax 22,456 20,018 Corporate — 3,397 Totals $ 369,039 $ 350,936 Changes in total deferred revenue, including long-term, were as follows (in thousands): June 30, 2019 Balance, beginning of period December 31, 2018 $ 350,936 Deferral of revenue 460,351 Recognition of deferred revenue (442,248 ) Balance, end of period $ 369,039 Transaction Price Allocated to the Remaining Performance Obligations The aggregate amount of transaction price allocated to the remaining performance obligations represents contracted revenue that has not yet been recognized ("backlog"), which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. Backlog as of June 30, 2019 , was $1.4 billion , of which we expect to recognize approximately 49% as revenue over the next 12 months and the remainder thereafter.

Debt Disclosure [Abstract]
Revolving Line of Credit	Revolving Line of Credit On November 16, 2015, we entered into a $300 million credit agreement with various lender parties and Wells Fargo Bank, National Association, as Administrative Agent (the “Credit Facility”). The Credit Facility provides for a revolving credit line up to $300 million , including a $10 million sublimit for letters of credit. The Credit Facility matures on November 16, 2020 . Borrowings under the Credit Facility may be used for general corporate purposes, including working capital requirements, acquisitions and share repurchases. Borrowings under the Credit Facility bear interest at a rate of either (1) Wells Fargo Bank’s prime rate (subject to certain higher rate determinations) plus a margin of 0.25% to 1.00% or (2) the 30, 60, 90 or 180 day LIBOR rate plus a margin of 1.25% to 2.00% . As of June 30, 2019 , the interest rates were 5.75% under the Wells Fargo Bank's prime rate and approximately 3.65% under the 30-day LIBOR option. The Credit Facility is secured by substantially all of our assets. The Credit Facility requires us to maintain certain financial ratios and other financial conditions and prohibits us from making certain investments, advances, cash dividends or loans, and limits incurrence of additional indebtedness and liens. As of June 30, 2019 , we were in compliance with those covenants. As of June 30, 2019 , we had outstanding borrowings of $15.0 million at an interest rate of approximately 3.65% , under a 30-day LIBOR contract.

Income Tax Disclosure [Abstract]
Income Tax Provision	Income Tax Provision We had an effective income tax rate of 12.1% and 17.0% for the three and six months ended June 30, 2019 , respectively, compared to negative 3.9% and 0.2% for the three and six months ended June 30, 2018 , respectively. The increase in the effective tax rate for the three and six months ended June 30, 2019 , as compared to the same period in 2018 was principally due to the decrease in excess tax benefits related to stock incentive awards. The effective income tax rates for the periods presented were different from the statutory United States federal income tax rate of 21% due to excess tax benefits related to stock incentive awards, state income taxes, non-deductible business expenses, and the tax benefit of research tax credits. The excess tax benefits related to stock incentive awards realized was $5.4 million and $7.0 million for the three and six months ended June 30, 2019 , respectively, compared to $11.5 million and $20.7 million for the three and six months ended June 30, 2018 , respectively. Excluding the excess tax benefits, the effective rate was 26.9% and 26.8% for the three and six months ended June 30, 2019 , compared to 26.7% and 27.0% for the three and six months ended June 30, 2018 , respectively.

Segment Reporting [Abstract]
Segment and Related Information	Segment and Related Information We provide integrated information management solutions and services for the public sector, with a focus on local governments. We provide our software systems and services and appraisal services through five business units, which focus on the following products: • financial management, education and planning, regulatory and maintenance software solutions; • financial management, municipal courts, planning, regulatory and maintenance, and land and vital records management software solutions; • courts and justice and public safety software solutions; • data and insights solutions; and • appraisal and tax software solutions and property appraisal services. In accordance with ASC 280-10, Segment Reporting, the financial management, education and planning, regulatory and maintenance software solutions unit; financial management, municipal courts, planning, regulatory and maintenance, and land and vital records management software solutions unit; courts and justice and public safety software solutions unit; and the data and insights solutions unit meet the criteria for aggregation and are presented in one reportable segment, the Enterprise Software (“ES”) segment. The ES segment provides public sector entities with software systems and services to meet their information technology and automation needs for mission-critical “back-office” functions such as financial management and courts and justice processes; public safety; planning, regulatory and maintenance; land and vital records management, and data analytics. The Appraisal and Tax (“A&T”) segment provides systems and software that automate the appraisal and assessment of real and personal property as well as property appraisal outsourcing services for local governments and taxing authorities. Property appraisal outsourcing services include: the physical inspection of commercial and residential properties; data collection and processing; computer analysis for property valuation; preparation of tax rolls; community education; and arbitration between taxpayers and the assessing jurisdiction. We evaluate performance based on several factors, of which the primary financial measure is business segment operating income. We define segment operating income for our business units as income before non-cash amortization of intangible assets associated with their acquisitions, interest expense and income taxes. Segment operating income includes intercompany transactions. The majority of intercompany transactions relate to contracts involving more than one unit and are valued based on the contractual arrangement.

Accounting Policies [Abstract]
Use of estimates	USE OF ESTIMATES The preparation of our financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires us 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include revenue recognition, determining the nature and timing of satisfaction of performance obligations, determining the standalone selling price ("SSP") of performance obligations, variable consideration, and other obligations such as returns and refunds; loss contingencies; the estimated useful life of deferred commissions; the carrying amount and estimated useful lives of intangible assets; the carrying amount of operating lease right-of-use assets and operating lease liabilities; determining share-based compensation expense; the valuation allowance for receivables; and determining the potential outcome of future tax consequences of events that have been recognized on our consolidated financial statements or tax returns. Actual results could differ from estimates.
Revenue recognition	REVENUE RECOGNITION Nature of Products and Services: We earn revenue from software licenses, royalties, subscription-based services, software services, post-contract customer support (“PCS” or “maintenance”), hardware, and appraisal services. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We determine revenue recognition through 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 • Recognition of revenue when, or as, we satisfy a performance obligation Most of our software arrangements with customers contain multiple performance obligations that range from software licenses, installation, training, and consulting to software modification and customization to meet specific customer needs (services), hosting, and PCS. For these contracts, we account for individual performance obligations separately when they are distinct. We evaluate whether separate performance obligations can be distinct or should be accounted for as one performance obligation. Arrangements that include software services, such as training or installation, are evaluated to determine whether the customer can benefit from the services either on their own or together with other resources readily available to the customer and whether the services are separately identifiable from other promises in the contract. The transaction price is allocated to the distinct performance obligations on a relative SSP basis. We determine the SSP based on our overall pricing objectives, taking into consideration market conditions and other factors, including the value of our contracts, the applications sold, customer demographics, and the number and types of users within our contracts. Revenue is recognized net of allowances for sales adjustments and any taxes collected from customers, which are subsequently remitted to governmental authorities. Significant Judgments: Our contracts with customers often include multiple performance obligations to a customer. When a software arrangement (license or subscription) includes both software licenses and software services, judgment is required to determine whether the software license is considered distinct and accounted for separately, or not distinct and accounted for together with the software services and recognized over time. The transaction price is allocated to the separate performance obligations on a relative SSP basis. We determine the SSP based on our overall pricing objectives, taking into consideration market conditions and other factors, including the value of our contracts, the applications sold, customer demographics, and the number and types of users within our contracts. We use a range of amounts to estimate SSP when we sell each of the products and services separately and need to determine whether there is a discount to be allocated based on the relative SSP of the various products and services. In instances where SSP is not directly observable, such as when we do not sell the product or service separately, we determine SSP using the expected cost-plus margin approach. For arrangements that involve significant production, modification or customization of the software, or where software services otherwise cannot be considered distinct, we recognize revenue as control is transferred to the customer over time using progress-to-completion methods. Depending on the contract, we measure progress-to-completion primarily using labor hours incurred, or value added. The progress-to-completion method generally results in the recognition of reasonably consistent profit margins over the life of a contract because we can provide reasonably dependable estimates of contract billings and contract costs. We use the level of profit margin that is most likely to occur on a contract. If the most likely profit margin cannot be precisely determined, the lowest probable level of profit margin in the range of estimates is used until the results can be estimated more precisely. These arrangements are often implemented over an extended time period and occasionally require us to revise total cost estimates. Amounts recognized in revenue are calculated using the progress-to-completion measurement after giving effect to any changes in our cost estimates. Changes to total estimated contract costs, if any, are recorded in the period they are determined. Estimated losses on uncompleted contracts are recorded in the period in which we first determine that a loss is apparent. Typically, the structure of our arrangements does not give rise to variable consideration. However, in those instances whereby variable consideration exists, we include in our estimates additional revenue for variable consideration when we believe we have an enforceable right, the amount can be estimated reliably and its realization is probable.
Contract balances	Contract Balances: Accounts receivable and allowance for doubtful accounts Timing of revenue recognition may differ from the timing of invoicing to customers. We record an unbilled receivable when revenue is recognized prior to invoicing, or deferred revenue when revenue is recognized subsequent to invoicing. For multi-year agreements, we generally invoice customers annually at the beginning of each annual coverage period. We record an unbilled receivable related to revenue recognized for on-premises licenses as we have an unconditional right to invoice and receive payment in the future related to those licenses. At June 30, 2019 , and December 31, 2018 , total current and long-term accounts receivable, net of allowance for doubtful accounts, was $401.9 million and $314.9 million , respectively. We have recorded unbilled receivables of $118.3 million and $104.2 million at June 30, 2019 , and December 31, 2018 , respectively. Included in unbilled receivables are retention receivables of $12.9 million and $12.2 million at June 30, 2019 , and December 31, 2018 , respectively, which become payable upon the completion of the contract or completion of our fieldwork and formal hearings. Unbilled receivables expected to be collected within one year have been included with accounts receivable, current portion in the accompanying condensed consolidated balance sheets. Unbilled receivables and retention receivables expected to be collected past one year have been included with accounts receivable, long-term portion in the accompanying condensed consolidated balance sheets. We maintain allowances for doubtful accounts, which are provided at the time the revenue is recognized. Since most of our customers are domestic governmental entities, we rarely incur a loss resulting from the inability of a customer to make required payments. Events or changes in circumstances that indicate the carrying amount for the allowances for doubtful accounts may require revision, include, but are not limited to, deterioration of a customer’s financial condition, failure to manage our customer’s expectations regarding the scope of the services to be delivered, and defects or errors in new versions or enhancements of our software products.
Leases	LEASES We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities on our consolidated balance sheets. We currently do not have any finance lease arrangements. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date of the lease in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components, which are generally accounted as a single lease component.
Recently adopted and issued accounting pronouncements	RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS Leases. We adopted Topic 842 using the transition method that allows us to initially apply the guidance at the adoption date of January 1, 2019, and recognized a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. We used the package of practical expedients that allows us to not reassess: (1) lease classification for any expired or existing leases and (2) initial direct costs for any expired or existing leases. We did not elect to use the hindsight application for evaluating the life of the lease arrangement. The impact of adoption is reflected in the financial information herein. For additional details, see Note 10 to our condensed consolidated financial statements. The impact of Topic 842 on our consolidated balance sheet beginning January 1, 2019, included the recognition of ROU assets and lease liabilities for operating leases, while our accounting for finance leases remained substantially unchanged. We had no finance leases prior to the adoption of Topic 842 and currently do not have any. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, (“ASU 2016-13”). ASU 2016-13 changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, held-to-maturity debt securities and loans, and requires entities to use a new forward-looking expected loss model that will result in the earlier recognition of allowance for losses. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for a fiscal year beginning after December 15, 2018, including interim periods within that fiscal year. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We are currently assessing the potential impact of ASU 2016-13 on our consolidated financial statements and results of operations.
