What must contractors file to receive payment for labor hour contracts?

To receive payment for labor hour contracts, contractors are required to file vouchers. Vouchers serve as formal requests for payment and are essential in the contracting process to ensure that contractors can account for services rendered and the associated costs. When a contractor submits a voucher, it typically includes details of the labor hours worked, costs incurred, and other relevant financial information, which the contracting officer reviews for accuracy and compliance with contract terms before approving payment.

While wage statements, expense reports, and direct invoices may play roles in the overall accounting and payment process in different contexts or types of contracts, they do not specifically fulfill the requirement inherent to labor hour contracts as effectively as vouchers do. Vouchers are specifically designed to provide a comprehensive and formal method for detailing the labor performed and justifying the payment request, thereby making them the appropriate choice for this scenario.
