CY2021	us-gaap	Use Of Estimates UseOfEstimates	The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, which requires management to make estimates and assumptions. These estimates, judgments and assumptions can affect the reported amounts in the financial statements and the footnotes thereto. Actual results could differ materially from these estimates. On an ongoing basis, we evaluate our estimates, assumptions and judgments. Significant estimates inherent to the preparation of financial statements include: revenue recognition; the allowances for doubtful accounts and sales returns; contract assets; internally developed software; goodwill and intangible assets; business combinations, including contingent consideration; and income taxes, including valuation allowance and uncertain tax positions. We base our estimates on historical experience, market participant fair value considerations, projected future cash flows, and various other factors that are believed to be reasonable under the circumstances. Actual amounts could differ significantly from these estimates.
