Accounts Receivable, Net

Accounts receivable primarily consist of amounts billed currently due from customers. Accounts receivable are presented net of an allowance for credit losses, which is an estimate of amounts that may not be collectible. In determining the amount of the allowance at each reporting date, the Company makes judgments about general economic conditions, historical write-off experience and any specific risks identified in customer collection matters, including the aging of unpaid accounts receivable and changes in customer financial conditions. Account balances are written off after all means of collection are exhausted and the potential for non-recovery is determined to be probable. Adjustments to the allowance for credit losses are recorded as general and administrative expenses in the condensed consolidated statements of operations and comprehensive loss.

Changes in the allowance for credit losses were as follows:

	Six Months Ended June 30, 2022			Year Ended December 31, 2021
Allowance for credit losses, beginning of the    period	$	1,809		$	1,556
Provisions		(308	)		714
Write-offs		(49	)		(461	)
Allowance for credit losses, end of the period	$	1,452		$	1,809

The Company has rights to consideration for services completed but not billed at the reporting date. Unbilled receivables are classified as receivables when the Company has the right to invoice the customer. The amount of unbilled accounts receivable included within accounts receivable on the consolidated balance sheet was $4,339 and $5,697 as of June 30, 2022 and December 31, 2021, respectively. The amount of unbilled accounts receivable included within other assets on the consolidated balance sheet was zero as of June 30, 2022 and $781as of December 31, 2021, respectively.
