| Pay vs Performance Disclosure [Table] | |||
| Pay vs Performance [Table Text Block] | Pay Versus Performance Pay Versus Performance Table The following table sets forth the pay versus performance disclosures required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, for each of the last three completed fiscal years. Because of the emphasis our executive compensation program places on equity compensation, as discussed in “Our Pay—Compensation Discussion and Analysis,” there may be large increases or decreases in the calculation of “compensation actually paid” to our CEO and NEOs on a year-to-year basis due to fluctuations in our stock price. This disclosure has been prepared in accordance with Item 402(v) of Regulation S-K and does not necessarily reflect value actually realized by our CEO or NEOs. All values are presented in thousands, except for total shareholder return (“TSR”) data. Fiscal Year Summary Compensation Table Total for CEO ($) (1) Compensation Actually Paid to CEO ($) (2) Average Summary Compensation Table Total for Non-CEO NEOs ($) (3) Average Compensation Actually Paid to Non-CEO NEOs ($) (2) Value of Initial Fixed $100 Investment Based on: (4) Net Income ($) (6) Company Total Shareholder Return Peer Group Total Shareholder Return (5) 2023 392 (93,746) 7,481 4,738 116.33 118.53 487,706 2022 350 (57,913) 2,768 1,330 161.34 145.90 427,390 2021 346 326,077 2,460 4,104 188.55 131.76 379,998 (1) Our principal executive officer (PEO) for all covered fiscal years was our CEO, Mr. Gassner, and we have referred to him as our CEO throughout this disclosure. (2) We have made adjustments to the Summary Compensation Table (“SCT”) totals—as prescribed by Item 402(v) of Regulation S-K—to calculate the amounts disclosed above as “compensation actually paid.” These adjustments are disclosed in the tables following footnote (6) below under the caption, “Footnote (2) continued: Adjustments to Determine Compensation Actually Paid.” (3) Our non-CEO NEOs for the fiscal year ended January 31, 2021 (fiscal 2021) were Ms. Zuppas and Messrs. Bowman, Tim Cabral, Alan Mateo, and Frederic Lequient, our former Senior Vice President, Global Customer Services. Our non-CEO NEOs for the fiscal year ended January 31, 2022 (fiscal 2022) were Messrs. Bowman, Lequient, Mateo, and Schwenger. Our non-CEO NEOs for the fiscal year ended January 31, 2023 (fiscal 2023) were Ms. Zuppas and Messrs. Bowman, Faddis, and Schwenger. (4) Assumes $100 invested on January 31, 2020 in stock or index, including reinvestment of dividends. (5) Our peer group is comprised of the S&P 1500 Application Software Index, as disclosed in our annual report pursuant to §229.201(e)(1)(ii) of Regulation S-K. (6) While our executive compensation program rewards individual and company performance via short-term and long-term equity incentive programs, we do not currently link the compensation actually paid to our NEOs to any company financial performance measure other than our stock price. We believe that both our annual stock bonus in the form of RSU awards and our annual long-term equity incentives in the form of stock options effectively emphasize an ownership culture and reward our executives for performance and value creation. Hence, we have not included an additional column for a Company-Selected Measure (as defined under §229.201(v)(2)(vi) of Regulation S-K) in this table because guidance issued under the pay versus performance rules states that stock price cannot be a “Company-Selected Measure” unless it is a performance metric in an incentive plan. See “Our Pay—Compensation Discussion and Analysis” for information about our compensation philosophy. Footnote (2) Continued: Adjustments to Determine Compensation Actually Paid The following tables disclose adjustments to the SCT totals to calculate the amount disclosed above as “compensation actually paid” for each covered fiscal year. The assumptions used for determining the fair values shown in these tables are materially consistent with those used to determine the fair values disclosed as of the grant date of such awards.

| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | Description of Relationship Between Our Cumulative TSR and Our Peer Group Cumulative TSR The following chart compares the cumulative TSR on our Class A common stock for the last three completed fiscal years to that of our peer group in the S&P 1500 Application Software Index over the same period. The chart assumes $100 was invested at the close of market on January 31, 2020 in our Class A common stock and the S&P 1500 Application Software Index and assumes the reinvestment of any dividends. The stock price performance on the chart is not necessarily indicative of future stock price performance. | ||
| Compensation Actually Paid vs. Net Income [Text Block] | Description of Relationship Between the Executive Compensation Actually Paid to Our NEOs and the Financial Performance Measures Included in Our Pay Versus Performance Table The following graphs illustrate the relationship between the executive compensation actually paid to our CEO and the average of the executive compensation actually paid to our other NEOs, and our cumulative TSR and net income for the last three completed fiscal years. The stock price performance and financial results on the graphs are not necessarily indicative of future stock price performance or financial results. | ||
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | (6) While our executive compensation program rewards individual and company performance via short-term and long-term equity incentive programs, we do not currently link the compensation actually paid to our NEOs to any company financial performance measure other than our stock price. We believe that both our annual stock bonus in the form of RSU awards and our annual long-term equity incentives in the form of stock options effectively emphasize an ownership culture and reward our executives for performance and value creation. Hence, we have not included an additional column for a Company-Selected Measure (as defined under §229.201(v)(2)(vi) of Regulation S-K) in this table because guidance issued under the pay versus performance rules states that stock price cannot be a “Company-Selected Measure” unless it is a performance metric in an incentive plan. See “Our Pay—Compensation Discussion and Analysis” for information about our compensation philosophy. | ||
| Total Shareholder Return Vs Peer Group [Text Block] | Description of Relationship Between Our Cumulative TSR and Our Peer Group Cumulative TSR The following chart compares the cumulative TSR on our Class A common stock for the last three completed fiscal years to that of our peer group in the S&P 1500 Application Software Index over the same period. The chart assumes $100 was invested at the close of market on January 31, 2020 in our Class A common stock and the S&P 1500 Application Software Index and assumes the reinvestment of any dividends. The stock price performance on the chart is not necessarily indicative of future stock price performance. | ||
