# Government Contract Factoring: How It Works

 October 9, 2026 9 min read by [FundBetter](https://www.fundbetter.com/) Share

Government contract factoring is the sale of invoices owed by a federal, state, or local government agency to a funding partner, which advances a share of the invoice value and collects payment from the agency directly. It addresses the same problem as commercial factoring, with an added layer: government receivables can be subject to statutory and agency-specific assignment rules on top of the contractual and lien issues that apply to private receivables, and those rules differ between federal work and state or local work.

On federal work a cash flow gap can arise even when the agency pays within the Prompt Payment window, because contractors may fund performance well before a proper invoice becomes payable.

## Where the gap actually comes from

Federal payment timing is regulated. Under FAR 32.904 and the Prompt Payment rules at 5 CFR 1315, for which the [Treasury Department's Bureau of the Fiscal Service](https://fiscal.treasury.gov/payments-from-government/prompt-payment) publishes guidance and the interest rate, the ordinary invoice payment due date is generally the later of 30 days after the designated billing office receives a proper invoice or 30 days after Government acceptance of the supplies or services, subject to contract terms, accepted discount terms, the accelerated payment rules and category-specific exceptions. Late payments generally accrue interest.

Federal construction work is an important exception, and it matters here because progress billing is where factoring gets complicated. Under FAR 32.904(d), progress payments based on contracting officer approval are generally due 14 days after the designated billing office receives a proper payment request, though the contracting officer may specify longer with documented justification. Retained amounts and final payments run on separate clocks. State and local payment practices vary by jurisdiction and are not governed by any of this.

The gap opens elsewhere. The clock runs from a proper invoice, and an invoice missing a required element is not proper, which sends it back. Receipt and acceptance timing can affect when the federal payment period begins, subject to the contract and the Prompt Payment rules. Progress billing, milestone approvals and retainage can make both the amount eligible for factoring and the timing of final payment more complex, and retainage may stay unavailable until much later. On top of that, contractors typically fund labor and materials from the first day of performance, well before any invoice is payable, unless the contract provides contract financing.

That is the shape of the problem, and it is a timing problem that factoring is built for.

## Which invoices qualify

Under FundBetter's published factoring criteria, eligible invoices should be for work already completed and delivered, carry clear payment terms, and be undisputed.

Progress billing complicates it. Invoices subject to retainage or tied to milestones are harder to advance, because the amount finally payable is not settled at the point of invoicing. Government construction contractors can encounter this, because progress billing and retainage complicate the amount available to advance.

Concentration is the other constraint. Facilities commonly cap how much of the advanced total comes from a single customer, often around 30 to 40 percent. A contractor whose revenue is one agency is the textbook case of concentration, so establish where that limit sits before assuming the whole ledger can be funded. Strong payer credit does not automatically remove the cap, although some funders that specialize in government receivables waive concentration limits for federal payers. Payer credit itself also varies. Federal obligations generally carry low payer-credit risk, although absent a no-setoff commitment in the contract the Government may set off certain pre-existing contractor liabilities against payments to the assignee. State, municipal and quasi-public agencies differ.

## The federal assignment framework

Federal contract receivables are governed by a specific framework under the Assignment of Claims Act and FAR Subpart 32.8. State and local requirements vary by jurisdiction, agency and contract, and can carry their own statutory and regulatory conditions.

On federal work, [a contractor may assign moneys due or to become due under a contract only where the contract specifies payments aggregating $1,000 or more, the assignment is made to a bank, trust company, or other financing institution, and the contract does not prohibit assignment](https://www.acquisition.gov/far/32.802). Unless the contract expressly permits otherwise, the assignment must also cover all unpaid amounts payable under the contract, be made to a single party, though that party may act as agent or trustee for several financing participants, and not be subject to further assignment.

That second condition is worth asking any funder about directly. The entity receiving the assignment has to qualify as a bank, trust company or other financing institution. A funder willing to buy commercial invoices is not necessarily positioned to take an assignment of a federal receivable, and it is a better question to ask at the outset than to discover at closing.

The notice requirement follows. The assignee sends written notice of assignment, with a true copy of the assignment instrument, to the contracting officer or agency head, the surety on any bond applicable to the contract, and the disbursing officer designated in the contract to make payment. Each applicable recipient matters, and where no bond applies to the contract there is no surety to notify.

One further point decides eligibility on a specific deal. The base FAR permits a contract to prohibit assignment of claims where the agency determines, under its own regulations, that the prohibition is in the Government's interest, but agency supplements can modify that rule, and some narrow it considerably; the DFARS, for example, allows the prohibition only in contracts for personal services. Check the FAR, the supplement that applies to the contracting agency, and the contract itself.

## Federal, state, and local compared

| | **Federal** | **State and local** |
| --- | --- | --- |
| Governing framework | Assignment of Claims Act and FAR Subpart 32.8, plus agency supplements | State law, agency rules and the contract |
| Payment timing | Generally the later of 30 days after the designated billing office receives a proper invoice or 30 days after Government acceptance; construction progress payments generally 14 days after receipt of a proper payment request, subject to the contract and the FAR | Varies by jurisdiction |
| Notice requirements | Contracting officer or agency head, applicable surety, disbursing officer | Set by state law, agency rules and the contract |
| Can assignment be blocked | Yes, where the agency determines under its regulations that a prohibition is in the Government's interest, as modified by any agency supplement | Yes, and terms differ widely |
| Practical first step | Read the contract's assignment clause | Read the contract's assignment clause |

The contract is the first document to read in both columns, though it is not the whole answer. State statutes, agency regulations and federal agency supplements can impose requirements the contract does not spell out.

## Turn Government Invoices into Working Capital with FundBetter

FundBetter is a national small business lender and funding marketplace, founded in 2018 and based in Miami. It may fund directly or connect a business with third-party lenders and funding partners, depending on which is the better fit, with funding from $5,000 to $5 million across eight products. Factoring is assessed on your invoices and your customers' credit rather than on your own financial profile alone. FundBetter's factoring criteria start at six or more months in business and center on eligible B2B or government invoices and a creditworthy customer base. Invoice eligibility, concentration and any existing liens on receivables also affect what can be funded. Checking your options uses a soft inquiry that does not affect your credit score; a hard inquiry happens later, with your permission, only on certain offers.

FundBetter can factor invoices issued to government agencies for work already completed and delivered, where they carry clear payment terms and are not in dispute. Whether a specific government receivable can be funded depends on the contract, the assignment requirements that apply to it, and the funding partner. Start with [invoice factoring](https://www.fundbetter.com/business-loans/invoice-factoring/), or compare it against a [business line of credit](https://www.fundbetter.com/business-loans/business-lines-of-credit/) on our [business loans hub](https://www.fundbetter.com/business-loans/).

Whether a government receivable can be funded turns on its contract as much as on the agency paying it. [Check your rate](https://www.fundbetter.com/apply/) with the contract to hand, and if it's federal and you're unsure how the Assignment of Claims Act applies to it, [talk it through with one of our advisors](https://www.fundbetter.com/contact/) first.

## Frequently asked questions

 Can any government invoice be factored?

No. Under FundBetter's published factoring criteria, the work should be completed and delivered, the terms clear, and the invoice undisputed. Beyond that, the contract may restrict or prohibit assignment, and requirements differ between federal, state, and local work.

 What is the Assignment of Claims Act?

It is the federal framework governing when and how a contractor may assign the money due under a government contract to a financing institution. The Federal Acquisition Regulation sets out the conditions and notice requirements, and agency supplements can modify them.

 Who has to be notified on a federal assignment?

The assignee sends written notice, with a true copy of the assignment instrument, to the contracting officer or agency head, the surety on any applicable bond, and the disbursing officer designated in the contract to make payment.

 Do government agencies pay slowly?

Federal agencies are subject to the Prompt Payment rules. The ordinary due date is generally the later of 30 days after the designated billing office receives a proper invoice or 30 days after Government acceptance, subject to the contract and accepted discount terms, while construction progress payments are generally due 14 days after the designated billing office receives a proper payment request, and retained amounts and final payments follow separate rules. Interest generally accrues on late payment, provided the invoice was proper and there is no dispute over the work. A cash flow gap can still arise from performance, invoicing, acceptance, milestone and retainage timing even when the agency ultimately pays within the applicable federal payment window.

 Does factoring affect my standing with the agency?

Assignment of claims is a recognized federal process, but the contractor still needs to follow the contract, the FAR and any applicable agency supplement, and the notice requirements that go with them.
