Through which system are final payments requested?

Final payments in contracting are processed through the Wide Area Workflow (WAWF) system. WAWF is designed to facilitate the electronic submission of invoices and the receipt of goods and services, enabling a streamlined process for contract closeout and payment requests. This system ensures that contractors can submit their final invoices securely and efficiently, while also allowing the government to corroborate receipt and acceptance of those invoices before issuing payment.

The other options serve different functions within the contracting and financial management framework. For example, the Contractor Performance Assessment Reporting System (CPARS) is focused on evaluating contractor performance and is not involved in payment processes. eTravel manages travel-related expenses and reimbursements for government personnel rather than contract payments. G-Invoicing is utilized for the creation and processing of intergovernmental transactions but does not directly handle final payment requests relating to contractor invoices. This distinction clarifies why WAWF is the appropriate choice for final payment requests in contracting practices.
