FAR 32.503-4—Approval of progress payment requests.
Plain-English Summary
FAR 32.503-4 explains how the Administrative Contracting Officer (ACO) approves progress payment requests once the contractor’s accounting system and controls have already been found reliable under FAR 32.503-3. It covers when the ACO may rely on the contractor’s accounting system and certification without first ordering an audit or review, including for initial requests on new contracts. It also addresses when the ACO should depart from that normal approach and request a review or audit—specifically when there is reason to question the accuracy or reliability of the contractor’s certification or when the contract appears likely to result in a loss. Finally, it sets the rule for partial withholding: if only part of a request is doubtful, the ACO should withhold only the questionable amount and pay the undisputed portion promptly, with later adjustment after review or audit. In practice, this section is designed to speed payment processing while preserving government protection against inaccurate, unsupported, or risky progress payment claims.
Key Rules
Rely on established systems
If the contractor’s reliability and accounting system adequacy have already been established, the ACO may approve a progress payment request based on that system and the contractor’s certification alone. No audit or separate review is required before payment in the ordinary case, including for initial requests on new contracts.
Do not request routine audits
The ACO should not automatically or routinely send progress payment requests for audit. The default approach is to process requests efficiently unless there is a specific reason to question the submission or the contract’s financial outlook.
Audit when certification is doubtful
If there is reason to question the reliability or accuracy of the contractor’s certification, the ACO should request a review or audit before approving payment or otherwise disposing of the request. This is a targeted safeguard, not a blanket requirement.
Audit when loss is likely
If the ACO believes the contract will involve a loss, the ACO should request a review or audit before approving the progress payment request. The rule recognizes that anticipated loss increases the risk that progress payments may not reflect proper earned amounts.
Withhold only the doubtful amount
When only part of a request is in doubt, the ACO should withhold only the questionable portion. Any amount that is clearly proper and due should be paid without waiting for the disputed issue to be resolved, with later adjustment after review or audit.
Responsibilities
Administrative Contracting Officer (ACO)
Approve progress payment requests using the contractor’s established accounting system and certification when reliability has been established; avoid routine audits; request review or audit when certification is questionable or the contract appears likely to incur a loss; withhold only the doubtful portion of a request and pay undisputed amounts promptly.
Contractor
Submit progress payment requests supported by accurate certifications and maintain an accounting system and controls that are reliable enough to support payment without routine audit; ensure the request is accurate because the ACO may rely on the certification unless there is reason to doubt it.
Reviewing/Auditing personnel
When requested by the ACO, examine the progress payment request to resolve concerns about certification accuracy, accounting support, or potential contract loss; provide findings that help the ACO decide whether to approve, withhold, or adjust payment.
Agency/Contract administration function
Maintain oversight processes that establish and document contractor reliability and accounting system adequacy under FAR 32.503-3 so the ACO can lawfully rely on them for progress payment approvals.
Practical Implications
This section is meant to keep cash flowing on performing contracts without forcing an audit every time a contractor submits a progress payment request.
The key judgment call for the ACO is whether there is a specific reason to doubt the certification or the contract’s financial outcome; absent that, the request can usually be processed quickly.
A common pitfall is over-auditing: routinely sending requests for review can delay payment and create unnecessary administrative burden.
Another pitfall is over-withholding: if only part of the request is questionable, the government should not hold back the entire payment when some amount is clearly due.
Contractors should understand that a reliable accounting system and credible certifications reduce payment friction, but any signs of inaccuracy, weak controls, or expected loss can trigger closer scrutiny and delay approval.
Official Regulatory Text
(a) When the reliability of the contractor and the adequacy of the contractor’s accounting system and controls have been established (see 32.503-3 of this section) the ACO may, in approving any particular progress payment request (including initial requests on new contracts), rely upon that accounting system and upon the contractor’s certification, without requiring audit or review of the request before payment. (b) The ACO should not routinely ask for audits of progress payment requests. However, when there is reason to- (1) Question the reliability or accuracy of the contractor’s certification; or (2) Believe that the contract will involve a loss, the ACO should ask for a review or audit of the request before payment is approved or the request is otherwise disposed of. (c) When there is reason to doubt the amount of a progress payment request, only the doubtful amount should be withheld, subject to later adjustment after review or audit; any clearly proper and due amounts should be paid without awaiting resolution of the differences.
