Our accounts receivable is primarily composed of trade receivables and unbilled receivables. Our trade receivables, which represent outstanding gross billings to clients, are reported net of allowance for doubtful accounts of $1.0 million as of December 31, 2022 and 2021. We establish an allowance for doubtful accounts based on management’s assessment of the collectability of specific accounts and by making a general provision for other potentially uncollectible amounts.

We make an accrual at the end of each accounting period for our obligations associated with the earned but unpaid wages of our WSEEs and for the accrued gross billings associated with such wages. These accruals are included in accrued worksite employee payroll cost and unbilled accounts receivable; however, these amounts are presented net in the Consolidated Statements of Operations. We generally require clients to pay invoices for service fees no later than the same day as the applicable payroll date. As such, we generally do not require collateral. Client prepayments directly attributable to accrued worksite employee payroll costs and unbilled revenues have been netted as we have the legal right of offset for these amounts. Unbilled accounts receivable consisted of the following:

	December 31,
(in thousands)	2022		2021
Accrued worksite employee payroll cost	$	513,397	$	409,653
Unbilled revenues	123,849		100,934
Client prepayments	(36,800)		(20,054)
Unbilled accounts receivable	$	600,446	$	490,533
