Requests for payment must be submitted in writing by the contractor.
Contractor payment requests shall:
Depending on the contract's payment provisions, a payment request may consist of, for example, a statement that specified work has been completed in a satisfactory manner, documentation showing that contract deliverables have been accepted by the Office, or information detailing the reimbursable costs incurred by the contractor.
Payment shall not be made unless authorized by the Contracting Officer. A Contracting Officer's payment authorization shall not preclude the Office from seeking repayment (or pursuing other remedies) if it subsequently concludes that the contractor was overpaid or otherwise mispaid.
In addition to the Contracting Officer's payment authorization, all payment requests must be certified and approved by the Office's Chief Financial Officer (or his or her designee) prior to making any payment.
