Government Contract Factoring & Financing Options Explained

In commercial business, factoring means selling an unpaid invoice to a third party — called a factor — at a discount. You get cash now (typically 80–95 percent of the invoice value); the factor collects the full amount from your customer later and keeps the difference as its fee. Simple enough. But federal contracts are not ordinary commercial receivables, and the government does not simply let you redirect its payments to whomever you like.

The legal backbone is the Assignment of Claims Act (31 U.S.C. 3727 and 41 U.S.C. 6305), which restricts who can receive payment on a federal contract ^[9]. The FAR implements this at Subpart 32.8 — Assignment of Claims, and the operative contract clause is FAR 52.232-23 (Assignment of Claims) ^[1][2]. Here is the plain-language version of what the statute and clause require:

• 1You may assign your right to receive payment only to a qualifying financing institution — a bank, trust company, or other federally recognized lender. You cannot assign claims to your cousin’s LLC.
• 2The contract must exceed $1,000 in total value.
• 3The assignment must cover all amounts payable under that contract — you cannot slice and dice individual invoices to multiple factors.
• 4Only one assignee (or a single trustee acting for a group of lenders) may be designated at any time.
• 5Both the Contracting Officer (CO) and the payment office must receive and acknowledge a proper Notice of Assignment before payments can be rerouted ^[1].

If the contract includes FAR 52.232-24 (Prohibition of Assignment of Claims), assignment is blocked entirely, and traditional factoring is off the table ^[3]. This clause appears less often, but you must check your contract before approaching any lender.

Set-off risk means the government’s right to reduce payments on your contract to recover debts you owe on other contracts or obligations. If the government exercises set-off, your factor receives less than the full invoice amount — and that makes the factor nervous. FAR 32.803 and the text of FAR 52.232-23 allow for an optional “no set-off” commitment, which tells the factor that the agency will not reduce assigned payments to recover unrelated debts ^[1][2]. In practice, agencies grant this sparingly, and factors price their fees accordingly when it is absent.

Electronic Funds Transfer (EFT) logistics are the second trap. Federal payments are routed using banking data stored in the contractor’s System for Award Management (SAM) record, per FAR 52.232-33 ^[8]. When you assign claims, the payment instructions must be updated so funds flow to the lender’s account — not yours. If the assignment paperwork is filed but SAM data is not aligned, the payment office may send money to the wrong account, creating delays and disputes.

For Department of Defense (DoD) contracts specifically, invoices are submitted and accepted through the Procurement Integrated Enterprise Environment (PIEE) — formerly known as Wide Area Workflow / Invoice Receipt Acceptance and Property Transfer (WAWF/iRAPT). The payment office within the Defense Finance and Accounting Service (DFAS) follows the recognized assignment, but the contractor and factor must ensure the PIEE submission aligns with the assignment documentation.

If you are a subcontractor, your invoice goes to the prime contractor — not the government. That makes your receivable a private commercial claim, governed by the Uniform Commercial Code (UCC), not the Assignment of Claims Act. Subcontractor factoring is generally simpler to arrange (no Notice of Assignment to the government), but your factor is taking credit risk on the prime, not on Uncle Sam. This distinction matters enormously when evaluating fees and terms.

Before paying factoring fees — which can range from 1 to 5 percent per invoice depending on volume, contract risk, and payment timing — consider the financing mechanisms the government itself provides under FAR Part 32. These tools put cash in your hands during performance, not after invoicing, and they cost you nothing beyond the administrative effort of requesting and managing them.

Progress payments are the workhorse financing mechanism for non-commercial, fixed-price contracts. As you incur costs performing the contract, you submit a progress payment request, and the government reimburses a percentage of your incurred, allocable, and allowable costs — before you deliver the final product or service ^[4].

The customary rates, set at FAR 32.501-1, are:

These rates mean you are financing only 15–20 percent of your costs out of pocket during performance — a massive improvement over waiting 30+ days after delivery to see a dime. For small businesses learning how to win government contracts, knowing you can request progress payments at the proposal stage is a competitive advantage: it signals to the CO that you understand contract financing and can manage cash flow responsibly.

One nuance practitioners should note: progress payments create a government lien on work-in-progress and materials. If you default, the government can take title to the work. Also, progress payments are generally not available on cost-reimbursement contracts, because those contracts already finance performance through interim vouchers under FAR 52.216-7.

Performance-Based Payments (PBPs) tie financing to the completion of defined milestones or measurable performance outcomes — not cost accumulation ^[5]. The FAR actually prefers PBPs over progress payments for non-commercial items because they align the government’s cash outflow with demonstrated progress rather than cost incurrence.

The key constraint: total PBPs may not exceed 90 percent of the contract price prior to delivery and acceptance (FAR 32.1004) ^[5]. That 90 percent cap is more generous than the 80–85 percent progress payment rates, which is one reason PBPs are attractive — but they require upfront negotiation of clear, measurable milestones, which adds complexity to proposal preparation.

If your contract is for commercial products or commercial services (as defined in FAR Part 2), the government can provide interim or advance payments under terms that are “customary” in the commercial marketplace ^[6]. The FAR identifies a customary advance payment amount of 15 percent of the contract price, with appropriate security and risk documentation required under FAR 32.206 and FAR 32.202-4 ^[6].

This mechanism is underutilized. Many contractors selling commercial items do not realize they can negotiate financing terms into the contract.

The table below summarizes all three government-provided mechanisms side by side:

Even without factoring or government financing, the law guarantees you timely payment. The Prompt Payment Act (31 U.S.C. 3901–3907), implemented at FAR Subpart 32.9 and clause FAR 52.232-25, requires agencies to pay proper invoices within 30 calendar days of receipt and acceptance ^[7]. If the agency pays late, it owes you interest at the U.S. Treasury’s Prompt Payment interest rate, which is updated quarterly ^[7].

Two accelerators can shorten that 30-day window further:

For contractors focused on how to win government contracts as a small business, these accelerators can materially reduce the cash flow gap that makes factoring necessary in the first place.

Factoring is not your only private-market option. Several alternatives exist, each with different cost profiles and risk characteristics:

Government contract lines of credit: Some banks offer revolving credit lines secured by your federal contract receivables. Unlike factoring, you retain ownership of the receivable and pay interest only on what you draw. These tend to be cheaper than factoring but require stronger creditworthiness.

SBA lending programs: The Small Business Administration’s (SBA) 7(a) loan program and CAPLines (Contract, Seasonal, Builders, and Working Capital lines of credit) are specifically designed to support small businesses with federal contract cash flow needs ^[10]. CAPLines can be structured as revolving lines against specific contract receivables, functioning somewhat like factoring but at lower cost and with SBA guarantees backing the lender’s risk.

Asset-based lending (ABL): Larger contractors may access ABL facilities where the lender advances funds against a portfolio of receivables, inventory, and equipment. ABL is more complex but provides greater flexibility than single-contract factoring.

The right choice depends on your contract portfolio size, credit history, how quickly you need cash, and how much you are willing to pay for speed. Factoring is the fastest but most expensive option. SBA-backed lending is the cheapest but requires more setup time and documentation.

Rather than defaulting to factoring because it is familiar, work through this framework for every new contract:

Start by reviewing the financing clauses in your current or upcoming contracts — specifically, look for FAR 52.232-23, any progress payment or PBP clauses, and FAR 52.232-25 (Prompt Payment). Model the cash flow gap on your most cash-intensive contract and calculate whether government-provided financing alone can cover it. If factoring is still necessary, approach only lenders experienced with federal invoice factoring assignments — and make sure your SAM registration and EFT data are current before filing a Notice of Assignment. The cheapest dollar of financing is the one you do not need; the second cheapest is the one the government provides for free.
