GAO is responsible for preparing and submitting invoices to the sponsor. Invoices that GAO typically prepares includes (but is not limited to):
- Cost-reimbursement invoices
- Fixed-price invoices
- GAX - State of Iowa voucher
- SF 270
- SF 1034 (and 1035)
- WAWF (Wide Area Work Flow) - DOD invoicing
There are times when GAO will allow the department to have responsibility of invoicing for their award, but these instances are handled on a case-by-case basis and should be approved by the GAO accountant.
