Key takeaways
- Plan for the gap between performance start and first payment, not between award and start.
- Your invoicing accuracy affects payment speed more than any financing product does.
- Financing costs money; fixing your invoicing process usually doesn’t.
- Model the gap before you bid, not after you win.
A first federal contract is frequently a cash flow crisis disguised as good news. You have won work, you are staffing up, payroll starts immediately — and the money arrives considerably later than a commercial contract would have trained you to expect.
Why the gap exists
Federal payment is not slow because anyone is being difficult. It is slow because it is procedural. Work is performed, then invoiced, then the invoice is reviewed against the contract terms, then it is approved, then it is paid. Each step has its own queue. Prompt Payment Act terms typically start the clock at a proper invoice — and a great deal turns on that word.
If you are a subcontractor, add the prime’s own review and payment cycle on top.
How long it really is
The mistake new contractors make is measuring from award. Measure from the first day you incur cost:
- Performance begins; payroll and overhead start immediately.
- You invoice at the end of a period — typically monthly, sometimes on milestones.
- The invoice is reviewed. Anything wrong sends it back to the start.
- Payment follows approval under the contract’s terms.
The exposure is your fully burdened cost for that whole span, not one month’s payroll. On a labour-heavy contract that number is often larger than the founder’s mental estimate by a multiple.
Fix invoicing before you finance anything
This is the least glamorous advice in federal contracting and the highest return. A rejected invoice does not delay payment by the time it takes to fix it — it restarts the entire review cycle.
- Confirm exactly what your contract defines as a proper invoice, including the supporting detail required.
- Match your timekeeping and accounting output to how the contract is priced.
- Invoice on a fixed schedule and never late — a late invoice is a late payment.
- Build the relationship with the contracting officer’s representative before you need to chase something.
- Reconcile every rejection and fix the root cause, not the individual invoice.
Contractors who do this consistently often find their perceived financing problem was an accounts-receivable problem.
Financing options and their trade-offs
Working capital lines of credit
The conventional route. Cheapest if you can qualify — which for a young company with no trading history against federal receivables is the difficulty.
Government-contract-specific lenders
Lenders who understand federal receivables and will advance against them. More expensive than a bank line, and they will want visibility into your contract and your invoicing discipline.
Invoice factoring
Selling receivables at a discount. Fast and widely available; the most expensive money in the list, and the cost compounds if your payment cycle is already slow. Check your contract terms on assignment of claims before assuming factoring is even permitted.
SBA-backed programmes
Several SBA programmes are designed for exactly this situation. Slower to arrange, materially cheaper. Worth starting before you need them.
Structuring the deal differently
Sometimes the answer is not financing at all: subcontracting under a prime with the balance sheet to carry the gap, or teaming rather than bidding as prime on your first pursuit. Less revenue, dramatically less risk.
Modelling it before you bid
The bid/no-bid conversation should include a cash question, not just a capability question. Model your fully burdened monthly cost across the expected gap, and ask plainly whether you can carry it if the first payment lands at the pessimistic end of the range.
If the answer is no, that is not necessarily a reason to walk away — but it is a reason to arrange financing before submission rather than after award, when you will be negotiating from a much weaker position.
