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.
