Summary of Significant Accounti

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Basis of presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") for interim financial reporting and applicable quarterly reporting regulations of the Securities and Exchange Commission ("SEC"). In management's opinion, the accompanying interim unaudited condensed consolidated financial statements include all adjustments necessary for a fair statement of the financial position of the Company as of June 30, 2023, the results of operations for the three and six months ended June 30, 2023 and 2022, cash flows for the six months ended June 30, 2023 and 2022, and stockholders' (deficit) equity for the three and six months ended June 30, 2023 and 2022. Certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with GAAP have been omitted from these interim unaudited condensed consolidated financial statements pursuant to the rules and regulations of the SEC. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022 ("Annual Report") filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2022 was derived from the Company's audited consolidated financial statements but does not include all disclosures required under GAAP. Changes in accounting policies There have been no material changes in the Company’s significant accounting policies and their application as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 . Fair value measurement The Company's financial assets that are included in cash and cash equivalents and that are measured at fair value on a recurring basis consisted of $171.2 million and $168.1 million at June 30, 2023 and December 31, 2022, respectively, and were invested in treasury money market funds. The fair value of the treasury money market funds is determined based on quoted market prices, which represents level 1 in the fair value hierarchy as defined by ASC 820. Trade and other receivables Trade and other receivables are primarily comprised of trade receivables, net of allowance for credit losses, contract assets and unbilled receivables. The Company records trade accounts receivable for its unconditional rights to consideration arising from the Company's performance under contracts with customers. The Company's standard billing terms are that payment is due upon receipt of invoice, payable generally within thirty to sixty days. The carrying value of such receivables, net of the allowance for credit losses, represents their estimated net realizable value. When developing its estimate of expected credit losses on trade and other receivables, the Company considers the available information relevant to assessing the collectability of cash flows, which includes a combination of both internal and external information relating to past events, current conditions, and future forecasts as well as relevant qualitative and quantitative factors that relate to the environment in which the Company operates. Contract assets represent conditional rights to consideration that have been recognized as revenue in advance of billing the customer. Unbilled receivables represent unconditional rights to consideration arising from revenue that have been recognized in advance of billing the customer. Deferred costs Sales commissions earned by the Company's sales representatives are considered incremental and recoverable costs of obtaining a customer contract. Sales commissions are deferred and amortized on a straight-line basis over the period of benefit, which the Company has determined to be five to eight years. The Company determined the period of benefit by taking into consideration its customer contracts, expected renewals of those customer contracts (as the Company currently does not pay an incremental sales commission for renewals), the Company's technology and other factors. The Company also defers amounts earned by employees other than sales representatives who earn incentive payments under compensation plans also tied to the value of customer contracts acquired. Deferred costs were $14.5 million and $14.8 million as of June 30, 2023 and December 31, 2022, respectively. Amortization expense for the deferred costs was $1.5 million and $1.4 million for the three months ended June 30, 2023 and 2022, respectively, and $2.9 million for both the six months ended June 30, 2023 and 2022. Amortization of deferred costs is included in selling and marketing expense in the accompanying unaudited condensed consolidated statements of comprehensive loss. Deferred implementation costs The Company capitalizes certain contract fulfillment costs, including personnel and other costs (such as hosting, employee salaries, benefits and payroll taxes), associated with arrangements where professional services are not distinct from other undelivered performance obligations in its customer contracts. The Company analyzes implementation costs and capitalizes those costs directly related to customer contracts expected to be recoverable to satisfy the undelivered performance obligations in those contracts. Deferred implementation costs are amortized ratably over the remaining contract term once the revenue recognition criteria for the respective performance obligation has been met and revenue recognition commences. Deferred implementation costs were $1.3 million and $1.6 million as of June 30, 2023 and December 31, 2022, respectively. Amortization expense for the deferred implementation costs was $0.2 million and $0.3 million for the three months ended June 30, 2023 and 2022, respectively, and $0.4 million and $0.6 million for the six months ended June 30, 2023 and 2022, respectively. Deferred implementation costs are included in prepaid and other current assets and other assets, noncurrent in the unaudited condensed consolidated balance sheets. Amortization of deferred implementation costs is included in cost of subscription and cost of services revenues in the accompanying unaudited condensed consolidated statements of comprehensive loss. Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever an event or change in circumstances indicates that the carrying amount of an asset or group of assets may not be recoverable. The impairment review includes comparison of future cash flows expected to be generated by the asset or group of assets with the associated assets’ carrying value. If the carrying value of the asset or group of assets exceeds its expected future cash flows (undiscounted and without interest charges), an impairment loss is recognized to the extent that the carrying amount of the asset exceeds its fair value. During the three and six months ended June 30, 2023, the Company recorded zero impairment charge. During the three and six months ended June 30, 2022, the Company recorded zero and $1.6 million, respectively, of impairment charge related to fixed assets. The 2022 impairment resulted from the Company's changed intentions for these assets in connection with a new agreement with a software vendor. Recently issued accounting pronouncements not yet adopted There have been no recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2023, as compared to the recent accounting pronouncements described in the Company's Annual Report, that are of significance or potential significance to the Company.

Disaggregation of Revenue [Abstract]
Disaggregation of Revenue [Text Block]	Disaggregation of Revenue Revenue by Geography The geographic information in the table below is presented for the three and six months ended June 30, 2023 and 2022.

Long-term Debt [Text Block]	Convertible Senior Notes The following is a summary of the Company's convertible senior notes as of June 30, 2023 (in thousands): Date of Issuance Unpaid Principal Balance Net Carrying Amount Contractual Interest Rates Current Noncurrent 1% Convertible Notes due in 2024 ("2024 Notes") May 2019 $ 143,750 $ 143,003 $ — 1% 2.25% Convertible Notes due in 2027 ("2027 Notes") September 2020 $ 150,000 $ — $ 147,522 2.25% The 2027 and 2024 Notes (collectively, the "Notes") are general unsecured obligations and rank senior in right of payment to all of the Company's indebtedness that is expressly subordinated in right of payment to the Notes, rank equally in right of payment with all of the Company's existing and future liabilities that are not so subordinated, are effectively junior to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness and are structurally subordinated to all indebtedness and other liabilities of the Company's subsidiaries (including trade payables but excluding intercompany obligations owed to the Company or its subsidiaries). Interest related to the 2027 Notes is payable semiannually in arrears in cash on March 15 and September 15 of each year, beginning on March 15, 2021. Interest related to the 2024 Notes is payable semi-annually in arrears on May 15 and November 15 of each year, beginning on November 15, 2019. The 2027 Notes mature on September 15, 2027 and the 2024 Notes mature on May 15, 2024, unless redeemed or converted in accordance with their terms prior to such date. At June 30, 2023, the Company had $184.6 million of cash and cash equivalents. The Company believes its existing cash and cash equivalents, including current estimates of future operating cash flows and funds available under its $50 million Credit Agreement (see Note 11), will provide adequate liquidity and capital resources to meet its operational requirements, anticipated capital expenditures, coupon interest and principal payments for the Notes for the next twelve months. Capital markets have tightened recently in response to the macroeconomic environment making new financing more difficult and/or expensive and the Company may not be able to obtain such financing on terms acceptable to it. Each $1,000 of principal of the 2027 Notes will initially be convertible into 23.9137 shares of the Company’s common stock, which is equivalent to an initial conversion price of approximately $41.82 per share. Each $1,000 of principal of the 2024 Notes will initially be convertible into 15.1394 shares of the Company’s common stock, which is equivalent to an initial conversion price of approximately $66.05 per share. The initial conversion price for the 2027 and the 2024 Notes is subject to adjustment upon the occurrence of certain specified events. As of June 30, 2023, the 2027 and 2024 Notes are not yet convertible and their remaining term is approximately 50 months and 10 months, respectively. As of June 30, 2023 and December 31, 2022, the fair value of the principal amount of the Notes in the aggregate was $285.3 million and $263.7 million, respectively. The estimated fair value was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including the Company's stock price and interest rates, which represents level 2 in the fair value hierarchy. The Notes consist of the following (in thousands): June 30, 2023 December 31, 2022 Principal $ 293,750 $ 293,750 Less: debt issuance cost, net of amortization (3,225) (3,971) Net carrying amount $ 290,525 $ 289,779 The following table sets forth total interest expense recognized related to the Notes (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Coupon interest $ 1,203 $ 1,203 $ 2,406 $ 2,406 Amortization of debt issuance costs 373 373 746 746 Total $ 1,576 $ 1,576 $ 3,152 $ 3,152 Capped Call Transactions In September 2020 and in May 2019, in connection with the offering of the 2027 and 2024 Notes, respectively, the Company entered into privately negotiated capped call transactions (collectively, the "Capped Call") with certain option counterparties. The Capped Call transactions cover, subject to customary anti-dilution adjustments, the number of shares of the Company’s common stock initially underlying the Notes, at a strike price that corresponds to the initial conversion price of the Notes, also subject to adjustment, and are exercisable upon conversion of the Notes. The Capped Call transactions are intended to reduce potential dilution to the Company’s common stock and/or offset any cash payments the Company will be required to make in excess of the principal amounts upon any conversion of Notes, and to effectively increase the overall conversion price of the 2027 Notes from $41.82 to $78.90 per share, and for the 2024 Notes from $66.05 to $101.62 per share. As the Capped Call transactions meet certain accounting criteria, they are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of the Capped Call was $25.3 million and $16.4 million for the 2027 and 2024 Notes, respectively, and was recorded as part of additional paid-in capital.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") for interim financial reporting and applicable quarterly reporting regulations of the Securities and Exchange Commission ("SEC"). In management's opinion, the accompanying interim unaudited condensed consolidated financial statements include all adjustments necessary for a fair statement of the financial position of the Company as of June 30, 2023, the results of operations for the three and six months ended June 30, 2023 and 2022, cash flows for the six months ended June 30, 2023 and 2022, and stockholders' (deficit) equity for the three and six months ended June 30, 2023 and 2022. Certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with GAAP have been omitted from these interim unaudited condensed consolidated financial statements pursuant to the rules and regulations of the SEC. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022 ("Annual Report") filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2022 was derived from the Company's audited consolidated financial statements but does not include all disclosures required under GAAP.
Accounting Standards Update and Change in Accounting Principle	Changes in accounting policies There have been no material changes in the Company’s significant accounting policies and their application as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 .
Fair value measurement	Fair value measurement The Company's financial assets that are included in cash and cash equivalents and that are measured at fair value on a recurring basis consisted of $171.2 million and $168.1 million at June 30, 2023 and December 31, 2022, respectively, and were invested in treasury money market funds. The fair value of the treasury money market funds is determined based on quoted market prices, which represents level 1 in the fair value hierarchy as defined by ASC 820.
Trade and Other Accounts Receivable, Unbilled Receivables, Policy [Policy Text Block]	Trade and other receivables Trade and other receivables are primarily comprised of trade receivables, net of allowance for credit losses, contract assets and unbilled receivables. The Company records trade accounts receivable for its unconditional rights to consideration arising from the Company's performance under contracts with customers. The Company's standard billing terms are that payment is due upon receipt of invoice, payable generally within thirty to sixty days. The carrying value of such receivables, net of the allowance for credit losses, represents their estimated net realizable value. When developing its estimate of expected credit losses on trade and other receivables, the Company considers the available information relevant to assessing the collectability of cash flows, which includes a combination of both internal and external information relating to past events, current conditions, and future forecasts as well as relevant qualitative and quantitative factors that relate to the environment in which the Company operates. Contract assets represent conditional rights to consideration that have been recognized as revenue in advance of billing the customer. Unbilled receivables represent unconditional rights to consideration arising from revenue that have been recognized in advance of billing the customer.
Revenue Recognition, Customer Acquisitions [Policy Text Block]	Deferred costs Sales commissions earned by the Company's sales representatives are considered incremental and recoverable costs of obtaining a customer contract. Sales commissions are deferred and amortized on a straight-line basis over the period of benefit, which the Company has determined to be five to eight years. The Company determined the period of benefit by taking into consideration its customer contracts, expected renewals of those customer contracts (as the Company currently does not pay an incremental sales commission for renewals), the Company's technology and other factors. The Company also defers amounts earned by employees other than sales representatives who earn incentive payments under compensation plans also tied to the value of customer contracts acquired. Deferred costs were $14.5 million and $14.8 million as of June 30, 2023 and December 31, 2022, respectively. Amortization expense for the deferred costs was $1.5 million and $1.4 million for the three months ended June 30, 2023 and 2022, respectively, and $2.9 million for both the six months ended June 30, 2023 and 2022. Amortization of deferred costs is included in selling and marketing expense in the accompanying unaudited condensed consolidated statements of comprehensive loss.
Deferred Charges, Policy [Policy Text Block]	Deferred implementation costs The Company capitalizes certain contract fulfillment costs, including personnel and other costs (such as hosting, employee salaries, benefits and payroll taxes), associated with arrangements where professional services are not distinct from other undelivered performance obligations in its customer contracts. The Company analyzes implementation costs and capitalizes those costs directly related to customer contracts expected to be recoverable to satisfy the undelivered performance obligations in those contracts. Deferred implementation costs are amortized ratably over the remaining contract term once the revenue recognition criteria for the respective performance obligation has been met and revenue recognition commences. Deferred implementation costs were $1.3 million and $1.6 million as of June 30, 2023 and December 31, 2022, respectively. Amortization expense for the deferred implementation costs was $0.2 million and $0.3 million for the three months ended June 30, 2023 and 2022, respectively, and $0.4 million and $0.6 million for the six months ended June 30, 2023 and 2022, respectively. Deferred implementation costs are included in prepaid and other current assets and other assets, noncurrent in the unaudited condensed consolidated balance sheets. Amortization of deferred implementation costs is included in cost of subscription and cost of services revenues in the accompanying unaudited condensed consolidated statements of comprehensive loss.
Impairment or Disposal of Long-Lived Assets, Policy	Impairment of Long-Lived AssetsLong-lived assets are reviewed for impairment whenever an event or change in circumstances indicates that the carrying amount of an asset or group of assets may not be recoverable. The impairment review includes comparison of future cash flows expected to be generated by the asset or group of assets with the associated assets’ carrying value. If the carrying value of the asset or group of assets exceeds its expected future cash flows (undiscounted and without interest charges), an impairment loss is recognized to the extent that the carrying amount of the asset exceeds its fair value. During the three and six months ended June 30, 2023, the Company recorded zero impairment charge. During the three and six months ended June 30, 2022, the Company recorded zero and $1.6 million, respectively, of impairment charge related to fixed assets. The 2022 impairment resulted from the Company's changed intentions for these assets in connection with a new agreement with a software vendor.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently issued accounting pronouncements not yet adopted There have been no recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2023, as compared to the recent accounting pronouncements described in the Company's Annual Report, that are of significance or potential significance to the Company.
