Government Contractor factoring

Government contractors can face long approval processes and special assignment rules.

Government contracts create a different receivables environment than commercial B2B invoicing. The federal government is an obligated payer with a generally strong payment record, but the process for getting invoices accepted, approved, and paid runs through procurement portals, agency contracting officers, and assignment-of-claims rules that commercial factoring programs are not always equipped to handle without advance preparation.

The Assignment of Claims Act governs how contractors can assign federal receivables to a financial institution. To make a valid assignment, the contractor must give proper notice to the government agency, often through a specific form and process outlined in the Federal Acquisition Regulation (FAR Part 32). Some agencies have additional requirements. Without a properly completed assignment and agency acknowledgment, the factor may not have enforceable rights to the government's payment.

Contracting officers and agency payment teams are not always familiar with factoring arrangements. Sending a notice of assignment to the wrong contracting officer, using the wrong form, or omitting required documentation can cause the payment to flow to the contractor's account rather than the factor's lockbox—even if the factoring arrangement is otherwise valid. Getting the agency acknowledgment right the first time is worth the extra preparation.

Federal payment timelines are governed by the Prompt Payment Act, which requires federal agencies to pay proper invoices within 30 days or pay interest on the delayed amount. In practice, timing also depends on when the invoice is accepted, whether the agency uses an electronic invoicing system, and whether the contractor's SAM.gov registration is current and not expired. A lapsed SAM registration can hold up payment even on otherwise valid invoices.

Invoice eligibility in government contract factoring is affected by the structure of the underlying contract. Fixed-price contracts with milestone or delivery acceptance produce invoices eligible once the government formally accepts the deliverable. Cost-reimbursable contracts create invoices based on incurred costs, which may require audit or review before final payment. Time-and-materials contracts create invoices eligible after submitted hours are approved by the contracting officer.

Concentration risk is relevant because many contractors work for a limited number of agencies or on a few major contracts. A single large task order may represent the majority of the contractor's receivables. If that contract is modified, delayed, or terminated for the government's convenience, the funded invoices may become uncertain. Understanding what termination-for-convenience language means for funded invoices is important before committing to a factoring program.

Businesses considering factoring against government receivables should confirm that their contracts do not have anti-assignment clauses overriding the Assignment of Claims Act, that their SAM registration is current, and that the factor understands federal invoicing requirements. A factor experienced with government contract receivables will be familiar with the assignment process, agency notice requirements, and the documentation differences between commercial and federal accounts.

The Assignment of Claims Act (31 U.S.C. § 3727) governs the assignment of federal contract receivables to factors. Under this statute, government contractors can assign payments due under federal contracts to financial institutions, including factoring companies, provided the assignment meets specific notice requirements. The contractor must submit an original assignment notice to the contracting officer, the disbursing officer, and the surety company if a payment bond exists. Missing any of these notice requirements can delay or prevent the factor from receiving payment directly from the federal government.

Payment timing under federal contracts often depends on the contracting agency, the payment terms in the specific contract, and whether invoices are submitted through the agency's electronic invoicing system. Many agencies use the Invoice Processing Platform (IPP) or agency-specific portals that require the contractor to submit electronic invoices before payment is processed. Factors working with government contractors need to confirm that the payment routing can be updated within these electronic systems to direct funds to the factor's collection account rather than the contractor's bank account.

State and local government receivables present a different set of considerations from federal contracts. The Assignment of Claims Act does not apply to state contracts, and state laws governing the assignability of government receivables vary considerably. Some states restrict or prohibit assignment of public contract receivables; others permit it with notice requirements. Contractors working with state agencies should confirm the applicable state law and the specific contract's anti-assignment language before assuming government receivables are eligible for factoring.

Cash flow pattern

Invoices depend on contract performance, agency acceptance, portal submission, and federal assignment rules. Payment may be reliable but procedurally slow.

Typical invoice documents

• Government contract
• Invoice or voucher
• Acceptance record
• SAM registration context
• Assignment paperwork
• Aging report

Common factoring fit

Can fit approved government receivables when assignment rules are followed. The assignment process deserves separate review.

Contract clauses to check

• FAR assignment requirements
• Anti-assignment language
• Agency acknowledgment process
• Payment portal controls
• Debarment and registration requirements

Industry-specific risks

• Assignment of claims rules can be technical.
• Portal or acceptance delays can slow funding.
• Contract modifications may affect invoice eligibility.

What factoring does not solve

• It does not override federal assignment rules.
• It does not cure performance issues.
• It does not replace contract administration.
