Accounting Policies [Abstract]
Basis of Presentation	2. Basis of Presentation Unaudited interim consolidated financial statements The accompanying interim consolidated financial statements have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission ("SEC") for interim financial reporting. These consolidated statements are unaudited and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments and accruals) necessary to state fairly the consolidated balance sheets, consolidated statements of comprehensive income, consolidated statements of cash flows and consolidated statements of stockholders’ equity, for the periods presented in accordance with accounting principles generally accepted in the United States ("GAAP"). The consolidated balance sheet at December 31, 2017 , has been derived from the audited consolidated financial statements at that date. Operating results and cash flows for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2018 , or any other future period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted in accordance with the rules and regulations for interim reporting of the SEC. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2017 , and other forms filed with the SEC from time to time. Reclassifications Our revenue from "subscriptions" and "maintenance" and a portion of our "services and other" revenue have been combined within "recurring" revenue beginning in 2018. In order to provide comparability between periods presented, those amounts of revenue have been combined within "recurring" revenue in the previously reported consolidated statements of comprehensive income to conform to presentation of the current period. Similarly, "cost of subscriptions" and "cost of maintenance" and a portion of "cost of services and other" have been combined within "cost of recurring" in the previously reported consolidated statements of comprehensive income to conform to presentation of the current period. "Services and other" revenue has been renamed as "one-time services and other" and consists of revenue that did not meet the description of "recurring" revenue in the consolidated statements of comprehensive income. Basis of consolidation The consolidated financial statements include the accounts of Blackbaud, Inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Reportable segment We report our operating results and financial information in one operating and reportable segment. Our chief operating decision maker uses consolidated financial information to make operating decisions, assess financial performance and allocate resources. Our chief operating decision maker is our chief executive officer ("CEO"). Recently adopted accounting pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. ASU 2014-09 replaces most previous revenue recognition guidance in GAAP and requires the recognition of revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The standard also provides guidance on the recognition of costs related to obtaining and fulfilling customer contracts. We adopted ASU 2014-09 as of January 1, 2018 utilizing the full retrospective method of transition, which requires that the standard be applied to all periods presented. The impact of adopting ASU 2014-09 on our total revenues for 2017 and 2016 was not material. The primary impacts of adopting ASU 2014-09 relate to the deferral of incremental commission and other costs of obtaining contracts with customers and the increase to the amortization period for those costs. Previously, we deferred only direct and incremental commission costs to obtain a contract and amortized those costs over the contract term, generally three years, as the revenue was recognized. Under the new standard, we defer all incremental commission and related fringe benefit costs to obtain a contract and amortize these costs in a manner that aligns with the expected period of benefit. We utilized the 'portfolio approach' practical expedient in ASC 606-10-10-4, which allows entities to apply the guidance to a portfolio of contracts with similar characteristics because the effects on the financial statements of this approach would not differ materially from applying the guidance to individual contracts. Using the 'portfolio approach' and taking into consideration our customer contracts, our technology and other factors, we determined the expected period of benefit to be five years. We do not generally pay commissions for contract renewals. Select adjusted unaudited financial statement information, which reflects our adoption of ASU 2014-09 is set forth below. Consolidated balance sheets: As of December 31, 2017 (dollars in thousands) As Reported Adjustments As Adjusted Accounts receivable, net of allowance $ 96,293 $ (614 ) $ 95,679 Prepaid expenses and other current assets $ 56,099 $ 5,879 $ 61,978 Other assets $ 24,083 $ 33,155 $ 57,238 Deferred revenue, current portion $ 276,456 $ (1,393 ) $ 275,063 Deferred tax liability $ 37,597 $ 10,426 $ 48,023 Retained earnings $ 195,649 $ 29,380 $ 225,029 Consolidated statements of comprehensive income: Three months ended March 31, 2017 (dollars in thousands, except per share amounts) As Reported (1) Adjustments As Adjusted Revenue Recurring $ 151,960 $ 8,087 $ 160,047 One-time services and other 31,661 (6,636 ) 25,025 Total revenue $ 183,621 $ 1,451 $ 185,072 Cost of Revenue Recurring $ 60,908 $ 2,967 $ 63,875 One-time services and other 24,574 (2,967 ) 21,607 Total cost of revenue $ 85,482 $ — $ 85,482 Operating expenses Sales, marketing and customer success $ 42,240 $ (1,243 ) $ 40,997 Net income $ 11,511 $ 1,631 $ 13,142 Basic earnings per share $ 0.25 $ 0.03 $ 0.28 Diluted earnings per share $ 0.24 $ 0.04 $ 0.28 (1) See the discussion of our reclassifications of previously reported revenue and costs of revenue above. Our adoption of ASU 2014-09 had no impact on our net cash provided by or used in operating, investing or financing activities for any of the periods reported. Except for the accounting policies for revenue recognition and deferred commissions (herein referred to as "costs of obtaining contracts") that were updated as a result of adopting ASU 2014-09, 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, 2017, filed with the SEC on February 20, 2018, that have had a material impact on our consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”), which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act (the “Tax Act”) signed into law in December 2017. We early adopted ASU 2018-02 effective January 1, 2018 and recorded an insignificant reclassification for the stranded tax effects resulting from the Tax Act from accumulated other comprehensive loss to retained earnings. Summary of significant accounting policies Revenue Recognition Our revenue is primarily generated from the following sources: (i) charging for the use of our software solutions in cloud-based and hosted environments; (ii) providing payment and transaction services; (iii) providing software maintenance and support services; and (iv) providing professional services, including implementation, consulting, training, analytic and other services. Revenues are recognized when control of these services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those 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; and • Recognition of revenue when, or as, we satisfy a performance obligation. Recurring Recurring revenue represents stand-ready performance obligations in which we are making our solutions or services available to our customers continuously over time or the value of the contract renews. Therefore, recurring revenue is generally recognized over time on a ratable basis over the contract term, beginning on the date that the solution or service is made available to the customer. Our recurring revenue contracts are generally for a term of three years at contract inception with one to three-year renewals thereafter, billed annually in advance and non-cancelable. Recurring revenue is comprised of fees for the use of our subscription-based software solutions, which includes providing access to cloud-based solutions, hosting services, online training programs, subscription-based analytic services, such as donor acquisitions and data enrichment, and payment services. Recurring revenue also includes fees from maintenance services for our on-premises solutions, services included in our renewable subscription contracts, subscription-based contracts for professional services and variable transaction revenue associated with the use of our solutions. Our payment services are offered with the assistance of third-party vendors. In general, when we are the principal in a transaction based on the factors identified in ASC 606-10-55-36 through 55-40, we record the revenue and related costs on a gross basis. Otherwise, we net the cost of revenue associated with the service against the gross revenue (amount billed to the customer) and record the net amount as revenue. For payment and transaction services, we have the right to invoice the customer in an amount that directly corresponds with the value to the customer of our performance to date. Therefore, we recognize revenue for these services over time based on the amount billable to the customer in accordance with the 'as invoiced' practical expedient in ASC 606-10-55-18. One-time services and other One-time services and other revenue primarily consists of fees for one-time consulting, analytic and onsite training services. We generally bill consulting services based on hourly rates plus reimbursable travel-related expenses. Fixed price consulting engagements are generally billed as milestones towards completion are reached. Revenue for all consulting services is recognized over time as the services are performed. We generally recognize analytic services revenue from donor prospect research engagements, the sale of lists of potential donors, data enrichment engagements and benchmarking studies at a point in time (upon delivery). We sell training at a fixed rate for each specific class at a per attendee price or at a packaged price for several attendees, and recognize the related revenue upon the customer attending and completing training. Contracts with multiple performance obligations Some of our contracts with customers contain multiple performance obligations. For these contracts, we account for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis. Standalone selling prices of our solutions and services are typically estimated based on observable transactions when the solutions or services are sold on a standalone basis. Costs of obtaining contracts, contract assets and deferred revenue We pay sales commissions at the time contracts with customers are signed or shortly thereafter, depending on the size and duration of the sales contract. Sales commissions and related fringe benefits earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. These costs are deferred and then amortized in a manner that aligns with the expected period of benefit, which we have determined to be five years. We determined the period of benefit by taking into consideration our customer contracts, including renewals, retention, our technology and other factors. We do not generally pay commissions for contract renewals. The related amortization expense is included in sales, marketing and customer success expense in our consolidated statements of comprehensive income. Amounts recognized as revenue in excess of amounts billed are recorded as contract assets within prepaid expenses and other current assets on our consolidated balance sheets. To the extent that our customers are billed for our solutions and services in advance of us satisfying the related performance obligations, we record such amounts in deferred revenue.

Earnings Per Share [Abstract]
Earnings Per Share	4. Earnings Per Share We compute basic earnings per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares and dilutive potential common shares outstanding during the period. Diluted earnings per share reflect the assumed exercise, settlement and vesting of all dilutive securities using the “treasury stock method” except when the effect is anti-dilutive. Potentially dilutive securities consist of shares issuable upon the exercise of stock options, settlement of stock appreciation rights and vesting of restricted stock awards and units. The following table sets forth the computation of basic and diluted earnings per share: Three months ended (dollars in thousands, except per share amounts) 2018 2017 Numerator: Net income $ 17,751 $ 13,142 Denominator: Weighted average common shares 47,019,603 46,501,761 Add effect of dilutive securities: Stock-based awards 989,792 981,079 Weighted average common shares assuming dilution 48,009,395 47,482,840 Earnings per share: Basic $ 0.38 $ 0.28 Diluted $ 0.37 $ 0.28 Anti-dilutive shares excluded from calculations of diluted earnings per share 24 199,199

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements We use a three-tier fair value hierarchy to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: • Level 1 - Quoted prices for identical assets or liabilities in active markets; • Level 2 - Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and • Level 3 - Valuations derived from valuation techniques in which one or more significant inputs are unobservable. Recurring fair value measurements Financial assets and liabilities measured at fair value on a recurring basis consisted of the following, as of the dates indicated below: Fair value measurement using (dollars in thousands) Level 1 Level 2 Level 3 Total Fair value as of March 31, 2018 Financial assets: Derivative instruments $ — $ 2,978 $ — $ 2,978 Total financial assets $ — $ 2,978 $ — $ 2,978 Fair value as of March 31, 2018 Financial liabilities: Derivative instruments $ — $ 229 $ — $ 229 Total financial liabilities $ — $ 229 $ — $ 229 Fair value as of December 31, 2017 Financial assets: Derivative instruments $ — $ 1,283 $ — $ 1,283 Total financial assets $ — $ 1,283 $ — $ 1,283 Our derivative instruments within the scope of ASC 815, Derivatives and Hedging , are required to be recorded at fair value. Our derivative instruments that are recorded at fair value include interest rate swaps. The fair value of our interest rate swaps was based on model-driven valuations using LIBOR rates, which are observable at commonly quoted intervals. Accordingly, our interest rate swaps are classified within Level 2 of the fair value hierarchy. We believe the carrying amounts of our cash and cash equivalents, restricted cash due to customers, accounts receivable, trade accounts payable, accrued expenses and other current liabilities and due to customers approximate their fair values at March 31, 2018 and December 31, 2017 , due to the immediate or short-term maturity of these instruments. We believe the carrying amount of our debt approximates its fair value at March 31, 2018 and December 31, 2017 , as the debt bears interest rates that approximate market value. As LIBOR rates are observable at commonly quoted intervals, our debt is classified within Level 2 of the fair value hierarchy. We did not transfer any assets or liabilities among the levels within the fair value hierarchy during the three months ended March 31, 2018 . Additionally, we did not hold any Level 3 assets or liabilities during the three months ended March 31, 2018 . Non-recurring fair value measurements Assets and liabilities that are measured at fair value on a non-recurring basis include intangible assets and goodwill, which are recognized at fair value during the period in which an acquisition is completed, from updated estimates and assumptions during the measurement period, or when they are considered to be impaired. These non-recurring fair value measurements, primarily for intangible assets acquired, are based on Level 3 unobservable inputs. In the event of an impairment, we determine the fair value of the goodwill and intangible assets using a discounted cash flow approach, which contains significant unobservable inputs and, therefore, is considered a Level 3 fair value measurement. The unobservable inputs in the analysis generally include future cash flow projections and a discount rate. There were no non-recurring fair value adjustments to intangible assets and goodwill during the three months ended March 31, 2018 , except for an insignificant business combination accounting adjustment to the initial fair value estimates of the assets acquired and liabilities assumed at the acquisition date from updated information obtained during the measurement period.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives Instruments	8. Derivative Instruments Cash flow hedges We generally use derivative instruments to manage our variable interest rate risk. In July 2017 , we entered into an interest rate swap agreement (the "July 2017 Swap Agreement"), which effectively converts portions of our variable rate debt under our credit facility to a fixed rate for the term of the July 2017 Swap Agreement. The notional value of the July 2017 Swap Agreement was $150.0 million with an effective date beginning in July 2017 through July 2021 . We designated the July 2017 Swap Agreement as a cash flow hedge at the inception of the contract. In February 2018 , we entered into an additional interest rate swap agreement (the " February 2018 Swap Agreement"), which effectively converts portions of our variable rate debt under our credit facility to a fixed rate for the term of the February 2018 Swap Agreement. The notional value of the February 2018 Swap Agreement was $50.0 million with an effective date beginning in February 2018 through June 2021 . We designated the February 2018 Swap Agreement as a cash flow hedge at the inception of the contract. The fair values of our derivative instruments were as follows as of: Asset Derivatives Liability Derivatives (dollars in thousands) Balance sheet location March 31, December 31, Balance sheet location March 31, December 31, Derivative instruments designated as hedging instruments: Interest rate swaps, current portion Prepaid expenses and other current assets $ — $ 145 Accrued expenses and other current liabilities $ — $ — Interest rate swaps, long-term portion Other assets 2,978 1,138 Other liabilities 229 — Total derivative instruments designated as hedging instruments $ 2,978 $ 1,283 $ 229 $ — The effects of derivative instruments in cash flow hedging relationships were as follows: Gain (loss) recognized in accumulated other comprehensive loss as of Location of gain (loss) reclassified from accumulated other comprehensive loss into income Gain (loss) reclassified from accumulated other comprehensive loss into income (dollars in thousands) March 31, Three months ended Interest rate swaps $ 2,748 Interest expense $ 20 March 31, Three months ended Interest rate swaps $ 343 Interest expense $ (119 ) Our policy requires that derivatives used for hedging purposes be designated and effective as a hedge of the identified risk exposure at the inception of the contract. Accumulated other comprehensive income (loss) includes unrealized gains or losses from the change in fair value measurement of our derivative instruments each reporting period and the related income tax expense or benefit. Changes in the fair value measurements of the derivative instruments and the related income tax expense or benefit are reflected as adjustments to accumulated other comprehensive income (loss) until the actual hedged expense is incurred or until the hedge is terminated at which point the unrealized gain (loss) is reclassified from accumulated other comprehensive income (loss) to current earnings. The estimated accumulated other comprehensive income as of March 31, 2018 that is expected to be reclassified into earnings within the next twelve months is insignificant . There were no ineffective portions of our interest rate swap derivatives during the three months ended March 31, 2018 and 2017 . See Note 12

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	9. Commitments and Contingencies Leases Total rent expense was $4.0 million for the three months ended March 31, 2018 and 2017 . Other commitments The term loans under the 2017 Credit Facility require periodic principal payments. The balance of the term loans and any amounts drawn on the revolving credit loans are due upon maturity of the 2017 Credit Facility in June 2022 . We have contractual obligations for third-party technology used in our solutions and for other services we purchase as part of our normal operations. In certain cases, these arrangements require a minimum annual purchase commitment by us. As of March 31, 2018 , the remaining aggregate minimum purchase commitment under these arrangements was approximately $68.7 million through 2023 . Solution and service indemnifications In the ordinary course of business, we provide certain indemnifications of varying scope to customers against claims of intellectual property infringement made by third parties arising from the use of our solutions or services. If we determine that it is probable that a loss has been incurred related to solution or service indemnifications, any such loss that could be reasonably estimated would be recognized. We have not identified any losses and, accordingly, we have not recorded a liability related to these indemnifications. Legal proceedings We are subject to legal proceedings and claims that arise in the ordinary course of business. We make a provision for a loss contingency when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. Unless otherwise specifically disclosed in this note, we have determined as of March 31, 2018 , that no provision for liability nor disclosure is required related to any claim against us because (a) there is not a reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim; (b) a reasonably possible loss or range of loss cannot be estimated; or (c) such estimate is immaterial.

Income Tax Disclosure [Abstract]
Income Taxes	10. Income Taxes Our income tax benefit and effective income tax rates, including the effects of period-specific events, were: Three months ended (dollars in thousands) 2018 2017 Income tax benefit $ (3,527 ) $ (1,960 ) Effective income tax rate (24.8 )% (17.5 )% The decrease in our effective income tax rate during the three months ended March 31, 2018 , when compared to the same period in 2017 , was primarily due to the impact of the discrete benefit to income tax expense relating to stock-based compensation items, calculated prior to the impact of the U.S. federal corporate tax rate change as a result of the Tax Act. This favorable impact was attributable to an increase in the market price for shares of our common stock, as reported by the Nasdaq Stock Market LLC ("Nasdaq"), as well as an increase in the number of stock awards that vested and were exercised. Most of our equity awards are granted during our first quarter and vest in subsequent years during the same quarter. This discrete benefit to income tax expense relating to stock-based compensation during the three months ended March 31, 2018 was reduced as a result of the decrease in the U.S. corporate tax rate. The decrease in our effective income tax rate during the three months ended March 31, 2018, as compared to the same period in 2017, was also attributable to the impact of the lower U.S. federal corporate tax rate on pre-tax income. In December 2017, the Tax Act was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. For the three months ended March 31, 2018, the Company obtained additional information affecting the provisional amount calculated for the transition tax as of December 31, 2017, however, the Company determined that the transition tax is still insignificant. The Tax Act eliminates the exceptions for performance-based compensation and CFO compensation from the 162(m) calculation. A transition rule allows for the grandfathering of performance-based compensation pursuant to a written binding contract in effect as of November 2, 2017. While there is negative discretion inherent in our performance-based compensation plans, it is our position that the intent is for historic contracts to be written and binding. As a result, we have not adjusted the ending estimated deferred tax assets for the performance-based stock compensation or the bonus accrual in our 2018 income tax provision.

The 2017 Credit Facility limits the amount of dividends payable and certain state laws restrict the amount of dividends distributed. In February 2018 , our Board of Directors approved an annual dividend rate of $0.48 per share to be made in quarterly payments. Dividend payments are not guaranteed and our Board of Directors may decide, in its absolute discretion, at any time and for any reason, not to declare and pay further dividends.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	13. Revenue Recognition The prior period financial information presented below has been adjusted to reflect our adoption of ASU 2014-09. Transaction price allocated to the remaining performance obligations As of March 31, 2018 , approximately $619 million of revenue is expected to be recognized from remaining performance obligations. We expect to recognize revenue on approximately 60% of these remaining performance obligations over the next 12 months, with the remainder recognized thereafter. We applied the practical expedient in ASC 606-10-50-14 and have excluded the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less (one-time services); and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed (payment services and usage). We also applied the practical expedient in ASC 606-10-65-1-(f)(3), whereby the transaction price allocated to the remaining performance obligations, or an explanation of when we expect to recognize that amount as revenue for all reporting periods presented before the date of the initial application, is not disclosed. Contract balances Our opening and closing balances of contract assets and deferred revenue were as follows: (in thousands) March 31, December 31, Contract assets $ 3,533 $ 3,136 Total deferred revenue 259,952 278,706 Contract assets remained relatively unchanged during the first quarter of 2018. The decrease in deferred revenue during the first quarter of 2018 was primarily due to less billings for recurring revenue contracts. Historically, due to the timing of customer budget cycles, we have an increase in customer contract renewals in our second and fourth quarters as compared to our first and third quarters. The amount of revenue recognized during the first quarter of 2018 that was included in the deferred revenue balance at the beginning of the period was approximately $123 million . The amount of revenue recognized during the first quarter of 2018 from performance obligations satisfied in prior periods was insignificant . Disaggregation of revenue We sell our cloud-based solutions and related services in two primary geographical markets: to customers in the United States, and to customers located outside of the United States. The following table presents our revenue by geographic area based on the address of our customers: Three months ended (dollars in thousands) 2018 2017 United States $ 175,923 $ 168,894 Other countries 28,261 16,178 Total revenue $ 204,184 $ 185,072 The General Markets Group ("GMG"), the Enterprise Markets Group ("EMG"), and the International Markets Group ("IMG") comprise our go-to-market organizations. The following is a description of each market group: • The GMG focuses on sales to all K-12 private schools, faith-based and arts and cultural organizations, as well as emerging and mid-sized prospects in North America; • The EMG focuses on sales to all healthcare and higher education institutions, corporations and foundations, as well as large and/or strategic prospects in North America; and • The IMG focuses on sales to all prospects and customers outside of North America.

Restructuring and Related Activities [Abstract]
Restructuring	14. Restructuring During 2017, in an effort to further our organizational objectives including, improved operating efficiency, customer outcomes and employee satisfaction, we initiated a multi-year plan to consolidate and relocate some of our existing offices to highly modern and more collaborative workspaces with short-term financial commitments. These workspaces are also more centrally located for our employees and closer to our customers and prospects. Restructuring costs expected to be incurred consist primarily of costs to terminate existing lease agreements, contractual lease payments, net of estimated sublease income, upon vacating space as part of the plan, as well as insignificant costs to relocate affected employees and write-off leasehold improvement assets that we will no longer use. We currently expect to incur before-tax restructuring costs associated with these activities of between $6.0 million and $8.0 million , with a significant portion of the remaining costs expected to be incurred through 2019 . We also expect to incur employee severance costs related to the plan; however, these costs cannot be reasonably estimated at this time. The following table summarizes our facilities optimization restructuring costs as of March 31, 2018 : Costs incurred during the three months ended Cumulative costs incurred as of (in thousands) March 31, 2018 By component: Contract termination costs $ 771 $ 1,366 Other costs 40 239 Total $ 811 $ 1,605 The change in our liability related to our facilities optimization restructuring during the three months ended March 31, 2018 , consisted of the following: Accrued at Increases for incurred costs Costs paid Accrued at (in thousands) December 31, 2017 March 31, 2018 By component: Contract termination costs $ 691 $ 771 $ (1,124 ) $ 338 Other costs — 40 (40 ) — Total $ 691 $ 811 $ (1,164 ) $ 338

Subsequent Events	15. Subsequent Events Reeher acquisition On April 30, 2018 , we acquired all of the outstanding equity securities, including all voting equity interests, of Reeher LLC, a Minnesota limited liability company (“Reeher”), pursuant to a securities purchase agreement. The acquisition expands our fundraising performance management capabilities and is intended to drive more effective fundraising and greater social good outcomes for our customers. We acquired the equity securities for an aggregate purchase price of $43.0 million , subject to certain adjustments set forth in the securities purchase agreement. The purchase price and related expenses were funded primarily through borrowings under the 2017 Credit Facility. As a result of the acquisition, Reeher has become a wholly-owned subsidiary of ours. We will include the operating results of Reeher, as well as any goodwill arising from the acquisition, in our consolidated financial statements from the date of acquisition. During the three months ended March 31, 2018 , we incurred insignificant acquisition-related expenses associated with the acquisition, which were recorded in general and administrative expense. Due to the timing of the transaction, the initial accounting for this acquisition, including the measurement of assets acquired, liabilities assumed and goodwill, is not complete and is pending detailed analyses of the facts and circumstances that existed as of the April 30, 2018

Recently adopted accounting pronouncements	Recently adopted accounting pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. ASU 2014-09 replaces most previous revenue recognition guidance in GAAP and requires the recognition of revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The standard also provides guidance on the recognition of costs related to obtaining and fulfilling customer contracts. We adopted ASU 2014-09 as of January 1, 2018 utilizing the full retrospective method of transition, which requires that the standard be applied to all periods presented. The impact of adopting ASU 2014-09 on our total revenues for 2017 and 2016 was not material. The primary impacts of adopting ASU 2014-09 relate to the deferral of incremental commission and other costs of obtaining contracts with customers and the increase to the amortization period for those costs. Previously, we deferred only direct and incremental commission costs to obtain a contract and amortized those costs over the contract term, generally three years, as the revenue was recognized. Under the new standard, we defer all incremental commission and related fringe benefit costs to obtain a contract and amortize these costs in a manner that aligns with the expected period of benefit. We utilized the 'portfolio approach' practical expedient in ASC 606-10-10-4, which allows entities to apply the guidance to a portfolio of contracts with similar characteristics because the effects on the financial statements of this approach would not differ materially from applying the guidance to individual contracts. Using the 'portfolio approach' and taking into consideration our customer contracts, our technology and other factors, we determined the expected period of benefit to be five years. We do not generally pay commissions for contract renewals. Select adjusted unaudited financial statement information, which reflects our adoption of ASU 2014-09 is set forth below. Consolidated balance sheets: As of December 31, 2017 (dollars in thousands) As Reported Adjustments As Adjusted Accounts receivable, net of allowance $ 96,293 $ (614 ) $ 95,679 Prepaid expenses and other current assets $ 56,099 $ 5,879 $ 61,978 Other assets $ 24,083 $ 33,155 $ 57,238 Deferred revenue, current portion $ 276,456 $ (1,393 ) $ 275,063 Deferred tax liability $ 37,597 $ 10,426 $ 48,023 Retained earnings $ 195,649 $ 29,380 $ 225,029 Consolidated statements of comprehensive income: Three months ended March 31, 2017 (dollars in thousands, except per share amounts) As Reported (1) Adjustments As Adjusted Revenue Recurring $ 151,960 $ 8,087 $ 160,047 One-time services and other 31,661 (6,636 ) 25,025 Total revenue $ 183,621 $ 1,451 $ 185,072 Cost of Revenue Recurring $ 60,908 $ 2,967 $ 63,875 One-time services and other 24,574 (2,967 ) 21,607 Total cost of revenue $ 85,482 $ — $ 85,482 Operating expenses Sales, marketing and customer success $ 42,240 $ (1,243 ) $ 40,997 Net income $ 11,511 $ 1,631 $ 13,142 Basic earnings per share $ 0.25 $ 0.03 $ 0.28 Diluted earnings per share $ 0.24 $ 0.04 $ 0.28 (1) See the discussion of our reclassifications of previously reported revenue and costs of revenue above. Our adoption of ASU 2014-09 had no impact on our net cash provided by or used in operating, investing or financing activities for any of the periods reported. Except for the accounting policies for revenue recognition and deferred commissions (herein referred to as "costs of obtaining contracts") that were updated as a result of adopting ASU 2014-09, 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, 2017, filed with the SEC on February 20, 2018, that have had a material impact on our consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income
Revenue recognition	Revenue Recognition Our revenue is primarily generated from the following sources: (i) charging for the use of our software solutions in cloud-based and hosted environments; (ii) providing payment and transaction services; (iii) providing software maintenance and support services; and (iv) providing professional services, including implementation, consulting, training, analytic and other services. Revenues are recognized when control of these services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those 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; and • Recognition of revenue when, or as, we satisfy a performance obligation. Recurring Recurring revenue represents stand-ready performance obligations in which we are making our solutions or services available to our customers continuously over time or the value of the contract renews. Therefore, recurring revenue is generally recognized over time on a ratable basis over the contract term, beginning on the date that the solution or service is made available to the customer. Our recurring revenue contracts are generally for a term of three years at contract inception with one to three-year renewals thereafter, billed annually in advance and non-cancelable. Recurring revenue is comprised of fees for the use of our subscription-based software solutions, which includes providing access to cloud-based solutions, hosting services, online training programs, subscription-based analytic services, such as donor acquisitions and data enrichment, and payment services. Recurring revenue also includes fees from maintenance services for our on-premises solutions, services included in our renewable subscription contracts, subscription-based contracts for professional services and variable transaction revenue associated with the use of our solutions. Our payment services are offered with the assistance of third-party vendors. In general, when we are the principal in a transaction based on the factors identified in ASC 606-10-55-36 through 55-40, we record the revenue and related costs on a gross basis. Otherwise, we net the cost of revenue associated with the service against the gross revenue (amount billed to the customer) and record the net amount as revenue. For payment and transaction services, we have the right to invoice the customer in an amount that directly corresponds with the value to the customer of our performance to date. Therefore, we recognize revenue for these services over time based on the amount billable to the customer in accordance with the 'as invoiced' practical expedient in ASC 606-10-55-18. One-time services and other One-time services and other revenue primarily consists of fees for one-time consulting, analytic and onsite training services. We generally bill consulting services based on hourly rates plus reimbursable travel-related expenses. Fixed price consulting engagements are generally billed as milestones towards completion are reached. Revenue for all consulting services is recognized over time as the services are performed. We generally recognize analytic services revenue from donor prospect research engagements, the sale of lists of potential donors, data enrichment engagements and benchmarking studies at a point in time (upon delivery). We sell training at a fixed rate for each specific class at a per attendee price or at a packaged price for several attendees, and recognize the related revenue upon the customer attending and completing training. Contracts with multiple performance obligations
Sales commissions	We pay sales commissions at the time contracts with customers are signed or shortly thereafter, depending on the size and duration of the sales contract. Sales commissions and related fringe benefits earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. These costs are deferred and then amortized in a manner that aligns with the expected period of benefit, which we have determined to be five years. We determined the period of benefit by taking into consideration our customer contracts, including renewals, retention, our technology and other factors. We do not generally pay commissions for contract renewals. The related amortization expense is included in sales, marketing and customer success expense in our consolidated statements of comprehensive income.
Deferred revenue	To the extent that our customers are billed for our solutions and services in advance of us satisfying the related performance obligations, we record such amounts in deferred revenue.
Recently issued accounting pronouncements	Recently issued accounting pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842)
Legal proceedings	Legal proceedingsWe are subject to legal proceedings and claims that arise in the ordinary course of business. We make a provision for a loss contingency when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case.
