Government Contract Factoring Explained: Financing Public-Sector Receivables
By Zolvo · 6 min read
Winning a government contract can be transformative for a small business, and also a cash-flow trap. Federal, state, and local agencies are among the most reliable payers in the economy, they almost never go bankrupt, but they pay on their own bureaucratic schedule, often 30 to 60 days or more after an invoice clears a multi-step approval process. A contractor that has to buy materials, make payroll, and mobilize on a new award cannot wait that long. Government contract factoring bridges the gap by advancing cash against those government receivables, and while it works like other factoring, the government payer makes it a distinct product with its own rules.
What makes government receivables different
In ordinary factoring, the risk that keeps a factor up at night is that the customer will not pay. With a government contract, that credit risk is nearly eliminated: the account debtor is a government agency that will pay what it owes. What replaces credit risk is process risk, the invoice must be correct, the work must be accepted, and the paperwork must move through the agency's approval chain. The money is highly likely to arrive; the question is when, and whether the billing was done exactly right.
That reliability is why factors are comfortable advancing against government receivables even for young contractors, and often at attractive terms. The strength of the payer, rather than the strength of the contractor's balance sheet, is what the factor is really financing.
The Assignment of Claims Act
The single most important legal feature of government contract factoring is the federal Assignment of Claims Act, and its state-level equivalents. Ordinarily, payments owed under a US government contract cannot simply be redirected to a third party. The Assignment of Claims Act creates the exception that makes factoring possible: it lets a contractor assign the right to receive payment to a financing party, such as a factor or a bank, under defined conditions.
In practice this means the assignment must be formally documented and acknowledged by the contracting officer and the disbursing office, so the agency knows to pay the factor. This is a more formal, more regulated version of the notice of assignment used in commercial factoring. A factor experienced in government work handles this process; one that is not can see assignments rejected or delayed, which is why sector experience matters more here than in almost any other vertical.
How government contract factoring works
- Perform and invoice. The contractor completes work or delivers goods under the contract and submits an invoice through the agency's required system, such as a federal invoicing portal.
- Advance against the receivable. The factor advances an advance rate against the invoice, often high given the payer's reliability, once the assignment is in place.
- Assignment of claims. The factor perfects its right to payment under the Assignment of Claims Act, with the contracting officer acknowledging that payment goes to the factor.
- The agency pays. The government remits payment on its cycle directly to the factor, which releases the reserve to the contractor minus its fee.
What it costs and who uses it
Government contract factoring is priced with a factoring fee as a percentage of the invoice. Because the payer is so creditworthy, rates can be competitive relative to riskier verticals, though the added administrative work of the assignment process and precise government billing is priced in. As with any factoring, the choice of recourse or non-recourse affects the fee, but non-recourse is less of a selling point here because the government rarely defaults; the more relevant risks are billing errors and disputes over performance, which recourse terms may still place on the contractor.
The businesses that use it are government contractors and subcontractors across services, construction, IT, staffing, and product supply, especially small and newly awarded firms that have won more work than their cash can carry. For any of them, factoring converts a slow but dependable government payment stream into the working capital needed to actually perform the contract.
Choosing a factor, and the servicing behind it
Because the Assignment of Claims Act process and government billing systems are unforgiving, the most important trait in a government-contract factor is sector experience: a factor that knows how to get an assignment acknowledged, bills the agency correctly the first time, and understands the relevant portals and payment cycles. Beyond that, the usual factors apply, competitive rate, high advance, fair recourse terms, and transparent contracts. The underlying need is a working capital gap created by the timing of dependable government payments.
For the factor, this vertical is a documentation and verification business: perfecting assignments, billing agencies precisely, and tracking payments through government cycles. That servicing and verification work is exactly what determines whether a government-contract book runs smoothly, and it is where Zolvo automates the back office.

Frequently asked questions
What is government contract factoring?
Government contract factoring is the financing of receivables owed to a business under federal, state, or local government contracts. The contractor sells its government invoices to a factor, which advances cash against them and collects when the agency pays. It lets contractors fund materials, payroll, and mobilization without waiting out the government's payment cycle, and it relies on the strength of the government payer rather than the contractor's balance sheet.
What is the Assignment of Claims Act and why does it matter?
The Assignment of Claims Act is the federal law that permits a contractor to assign the right to receive payment under a US government contract to a financing party such as a factor. Without it, government payments generally cannot be redirected to a third party. The assignment must be formally documented and acknowledged by the contracting officer, which is why factoring government contracts requires a factor experienced in the process.
Is government contract factoring cheaper because the government always pays?
Rates can be competitive because the payer is highly creditworthy and rarely defaults, which lowers the credit risk a factor prices for. However, the administrative work of perfecting the assignment and billing agencies precisely adds cost, and the real risks shift to billing errors and performance disputes rather than nonpayment. So while credit risk is low, the process demands are higher than ordinary commercial factoring.
Which businesses use government contract factoring?
Government contractors and subcontractors across services, construction, IT, staffing, and product supply use it, especially small or newly awarded firms whose contract wins outrun their available cash. Because government contracts pay reliably but slowly, factoring converts that dependable payment stream into immediate working capital to perform the work.
