How do small businesses fund a federal contract before getting paid?

Published 2026-08-04

How small businesses fund a federal contract before payment arrives

The government pays 30 days after a proper invoice, and small business contractors have an accelerated goal of 15 days. Firms bridge the gap between spending and payment with a working capital line of credit, assignment of claims to a lender, contract financing clauses in the contract itself, or factoring at a higher cost.

The problem is not that the government fails to pay. It is that payroll runs before the invoice clears, and a firm that just won its largest contract is often at its most fragile the following month.

Know the payment clock before you plan around it

Three timing rules in the Prompt Payment rules decide when cash actually lands:

RuleEffect
Standard due date30 days after the start of the payment period
Constructive acceptanceAcceptance is presumed 7 days after delivery unless stated otherwise
Improper invoice returnThe agency must return a defective invoice within 7 days of receipt

That last row is the one small contractors underuse. If an invoice is going to be rejected, the agency has to say so within a week, which means silence past day seven is itself information. A rejected invoice restarts the 30 day clock, so the gap between a clean invoice and a sloppy one is roughly a month of cash.

Separately, agencies are directed to accelerate payments to small business contractors with a goal of 15 days after a proper invoice. It is a goal rather than an entitlement, but it is worth naming in writing when you invoice.

The four routes firms actually use

A working capital line of credit is the cheapest normal answer. SBA's 7(a) program guarantees loans up to $5 million and includes a working capital pilot structured as a monitored line of credit rather than a term loan. Cost is ordinary bank pricing, and approval is slow enough that it should be arranged before you need it, not after award.

Assignment of claims is the mechanism most contractors have never heard of. Under federal law a contractor can assign the payments due under a contract to a bank, trust company or other financing institution, provided the contract calls for payments aggregating $1,000 or more and does not prohibit assignment. The lender is then paid directly by the government. Because the credit decision leans on a federal payment obligation rather than on the contractor's balance sheet, it often unlocks financing a young firm could not otherwise get.

Contract financing clauses put the government itself in the role of lender. Progress payments, performance-based payments and advance payments are negotiated into the contract before award, not bolted on afterwards, so the time to raise them is while the terms are still open.

Factoring or a merchant advance is the fast, expensive option. It is real financing and sometimes the right call for a single delayed receivable, but pricing it as an annualised rate rather than a flat fee is the honest comparison, and that number is usually uncomfortable.

Sequencing matters more than the instrument

The order these get arranged in decides whether they work.

  • Raise financing clauses during negotiation, because they cannot be added

once the contract is signed.

  • Set up the line of credit before the award, on the strength of the pipeline

rather than the win.

  • Use assignment of claims at award, when the payment obligation exists and

the lender has something concrete to secure against.

  • Keep factoring for specific stuck invoices, not as an operating model.

A firm that reaches the payroll problem before starting any of this has already lost the cheap options.

Watching for the moment financing becomes possible

Assignment of claims and most lending conversations need the award to exist in the public record, which happens on a reporting clock rather than instantly:

Each record carries the winner, agency, amount and place of performance with a link back to the federal source. If you are the subcontractor rather than the prime, the subcontracting guide covers finding the prime who now holds the money, and the set-aside programs reference covers the certifications that widen which contracts you can win in the first place. Route parameters and prices are at /docs.

What none of this fixes

Financing bridges a timing gap. It does not fix a contract priced below cost, and borrowing against a bad award accelerates the failure rather than preventing it. Federal work also carries compliance costs that are invisible in the bid: accounting system requirements, invoicing formats, and audit exposure that lasts years past performance. Price those before deciding how much working capital the job needs.

FAQ

How long does the government take to pay a small business?

Thirty days after a proper invoice is the standard rule, with an accelerated goal of 15 days for small business contractors. Payment against an improper invoice does not start until a corrected one is received, so invoice accuracy is worth more to cash flow than any financing product.

What is assignment of claims in plain terms?

You tell the government to send your contract payments to your lender instead of to you, and the lender advances you money against that. It is permitted when the contract calls for payments totalling $1,000 or more, the assignee is a financing institution, and the contract does not prohibit assignment.

Can I get paid faster if I am a subcontractor?

Sometimes. The accelerated payment rule extends to prime contractors that agree to pass payments along to their small business subcontractors within 15 days. It is a term to raise during subcontract negotiation, because it is not automatic.

Do I need financing arranged before I bid?

Not to bid, but before you win. Lenders move slower than contracting officers, and a facility arranged at the pipeline stage is available on the day of award. A firm starting the conversation after award typically waits through its first payroll.

Payment timing, constructive acceptance and invoice rejection rules are set at 5 CFR 1315.4. Accelerated payment to small business contractors is at 48 CFR 32.009-1, assignment of claims conditions at 48 CFR 32.802, and 7(a) loan limits at SBA.
