Section 532.905 - Payment documentation and processFor contracts of the type shown in 532.7201(a)(1) through (4):
(a) Contractors are to submit invoices or vouchers to the contracting officer for approval. Invoices must be annotated with the date of receipt, as required by FAR 32.905. That date will be used to determine interest penalties for late payments. The contracting officer or designee must review the processing of invoices or vouchers before payment to determine if the items and amounts claimed are consistent with the contract terms and represent prudent business transactions. The contracting officer must ensure that these payments are commensurate with physical and technical progress under the contract. If the contractor has not deducted questionable amounts from the invoice or amounts required to be withheld, the contracting officer must make the required deduction, except as provided in 532.7203. Subject to 532.7201, the contracting officer must note approval of any payment on (or attached to) the invoice or voucher submitted by the contractor and forward the invoice or voucher to the appropriate contract finance office for retention after certification and scheduling for payment by a disbursing office.(b) See GSAM 532.7203 for the handling of audit findings. 74 FR 54917 , Oct. 26, 2009
