Federal subcontract payment disputes often involve more than whether an invoice was submitted on time. The prime may assert withholding, setoff, backcharge, retainage, or recoupment rights that reduce the amount actually paid.
These rights should be reviewed separately. A backcharge tied to documented corrective work is different from an unrestricted right to offset any claim the prime has against the subcontractor on any project.
Construction prompt-payment clauses recognize withholding
FAR 52.232-27 allows qualifying construction subcontract terms to address withholding and retainage, including withholding amounts when the prime or subcontractor determines that part or all of a payment request should be withheld under the subcontract. The downstream contract should therefore define the procedure clearly.

Look for the scope of the deduction right
- May the prime withhold only amounts reasonably related to the disputed issue?
- Is written notice required before a backcharge is taken?
- Does the subcontractor receive an opportunity to cure defective work first?
- Can estimated future costs be withheld before the prime actually incurs them?
- Can the prime set off claims from unrelated projects or affiliates?
- Does a dispute over one invoice permit withholding of all other undisputed amounts?
Require enough information to evaluate a backcharge
A useful notice should identify the issue, contractual basis, amount or reasonable estimate, supporting records, and the action required to avoid or reduce the charge. Broad language allowing the prime to deduct any amount it deems appropriate can make cash flow difficult to forecast and disputes harder to resolve.
Connect deduction rights to liability and changes
Backcharges can overlap with warranty, indemnity, liquidated damages, reprocurement, and change provisions. Review whether a single event can generate multiple deductions and whether the subcontract's liability cap or consequential-damages waiver applies to those remedies.
