Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 10. Fair Value Measurements We utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible pursuant to the provisions of FASB Accounting Standards Codification, or ASC, Topic 820, Fair Value Measurements and Disclosures, or ASC 820. We determine fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. The carrying amounts for our cash and cash equivalents, accounts receivable, accounts payable, line of credit to the extent borrowings are outstanding and accrued expenses approximate fair value due to their short-term maturities. When considering market participant assumptions in fair value measurements, the following fair value hierarchy as established under ASC 820 distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: Level 1: Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2: Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3: Inputs are unobservable inputs for the asset or liability. We consider all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Our cash equivalents are comprised of money market funds, which are valued based on Level 1 inputs consisting of quoted prices in active markets. Our cash equivalents were $167.9 million and $117.9 million as of September 30, 2021 and December 31, 2020, respectively.
