When Does the Federal Government Pay You? What First-Time Contractors Need to Know
An award is a promise of work, not cash in your account. Understand the invoice and acceptance process before committing money to a supplier.
A profitable government order can still create a cash shortage. Your distributor may need payment before shipping, while the government pays after delivery, acceptance, and a correctly submitted invoice. Those events can be weeks apart.
What starts the payment clock?
Keep three events separate: delivery, acceptance, and invoice receipt. A carrier's delivery confirmation proves something arrived. It does not necessarily prove that the authorized government official accepted the supplies or that the payment office received a proper invoice.
For example, a hypothetical order is delivered on March 1. The designated office receives a proper invoice on March 2, and the government accepts the goods on March 5. Under the usual 30-day rule, the later acceptance event drives the ordinary due-date calculation. Check the governing clause for weekends, holidays, special products, and other exceptions.
Delayed acceptance does not erase every late-payment protection. For computing potential interest, the standard rules generally deem acceptance to occur on the seventh day after compliant delivery or performance when there is no disagreement. This constructive acceptance is an interest-calculation rule; it does not itself force actual acceptance or immediate payment. Contract-specific provisions matter. [1]
Does a small business get paid in 15 days?
The government has an accelerated-payment goal of 15 days for small-business contractors after receipt of a proper invoice and all required documentation, subject to the applicable rules. That goal creates no additional rights under the Prompt Payment Act. Build your cash plan around the contractual process and a realistic delay allowance rather than assuming guaranteed net-15 cash. [3]
A supplier's net-30 terms do not automatically solve the problem. Its clock may start when your order ships, before government acceptance and invoice processing are complete. Compare the actual dates, not just the labels.
What makes an invoice ready to process?
Use the contract's billing instructions. Under the standard Prompt Payment clause, required details include the contractor identity, invoice number/date, contract and order references, line-item descriptions, quantities, prices, applicable shipping/payment details, a contact for invoice problems, and any other required supporting documents. Taxpayer and banking information belong on an invoice only when the contract requires them there; otherwise use the designated registration or payment process. [2]
Our practical check is to reconcile the invoice against the award, modifications, delivery documents, and accepted quantities before submitting it. Save the submitted version and the system's receipt. An email in your sent folder is not proof that the designated billing system accepted the invoice.
For DoD, follow the WAWF routing instructions
Many Department of Defense contracts use Wide Area WorkFlow, or WAWF, within the Procurement Integrated Enterprise Environment (PIEE). The contract's WAWF instructions specify document types and routing codes for payment requests and receiving reports. Use those instructions rather than selecting a document type by guesswork. Fast Pay requests require the applicable contract clause. [4]
Before the first shipment, confirm who prepares the receiving report, who accepts the goods, which office handles payment, and whether you have the necessary system access. Preparing that information before delivery is easier than reconstructing it when a bill is already overdue.
An $18,000 order can need substantial working capital
The following numbers are hypothetical, not a supplier quote, financing offer, or profit forecast.
| Item | Amount |
|---|---|
| Government order revenue | $18,000 |
| Supplier product cost | $14,000 |
| Freight and required packaging | $800 |
| Illustrative financing and transaction costs | $400 |
| Remaining before other overhead and taxes | $2,800 |
If the supplier and carrier require payment before government funds arrive, you may need at least $14,800 available, plus any fees due during that interval and a reserve for problems. The $2,800 remainder is not automatically net profit. Your time, insurance, unexpected freight, returns, and other expenses can reduce it.
Map the order as dated cash movements: supplier deposit, remaining supplier balance, freight, delivery, acceptance, invoice receipt, expected government payment, and financing repayment. Confirm credit or purchase-order financing in writing before relying on it. An award alone does not establish lender approval or government advance-payment entitlement.
What should you do if payment is late?
- Confirm the submission. Locate the invoice receipt, document number, and current processing status.
- Identify the stalled step. Is the invoice rejected, awaiting acceptance, awaiting correction, or approved but unpaid?
- Contact the responsible office. Use the payment, acceptance, or contracting contact identified in the award, with the contract and invoice numbers ready.
- Keep a dated record. Save corrections, replies, acceptance evidence, and promised next steps.
- Review applicable remedies. Late-payment interest depends on the governing rules and facts; a disputed delivery or invoice is not automatically the same as an undisputed late payment. [2]
