Banking a Federal Contractor Through Slow Government Payment Terms

Government payment terms vary by agency and contract vehicle, but a genuine lag between delivering work and receiving payment is normal, sometimes 30 days or more past invoice submission even under standard terms. Pull your actual payment history across your current contracts rather than assuming the stated terms reflect reality, since agencies and payment offices vary in how consistently they hit those stated timelines, and a contract with a historically reliable payment office is a genuinely different cash-flow risk than one with a payment office known for delays.

A DCAA-compliant cost accounting system needs to allocate direct labor, materials, and indirect costs to specific contracts, and while that allocation happens primarily in your accounting system, giving major contracts their own bank account, using Relay's multiple checking accounts under one login, makes it much easier to trace cash flow against a specific contract when an auditor or contracting officer asks. It also gives a contract's own program manager a clean, specific number to manage against, rather than a share of a blended company total.

Once you know your actual payment timeline, build a reserve covering payroll and vendor obligations for that full lag period, funded before you commit to delivering on a new contract, not scrambled together after the first invoice goes unpaid past its due date. This is the single most important step for a contractor whose revenue depends on a payer that moves on its own schedule, and it matters most on your first contract with a new agency or a new contract vehicle, where you don't yet have your own payment history to rely on.

A short sequence for protecting cash against slow government payment:

1. Pull your actual payment history across current contracts instead of relying on the stated payment terms.
2. Size a reserve covering payroll and vendor obligations for the full lag you actually observe.
3. Fund that reserve before committing to deliver on a new contract, not after the first invoice runs late.
4. Give major contracts their own account so cash flow can be traced against a specific contract when an auditor asks.
5. Track the gap between provisional and actual indirect rates through the year to avoid a year-end surprise.

Operating cash sitting in reserve while a government invoice works through the payment process can still earn something rather than sitting completely idle; the effective federal funds rate averaged 3.63 percent in 2026¹, which sets a rough ceiling on what a bank sweep product can realistically pay on that cash before the bank's own spread. It's a modest benefit, but a real one on a meaningful reserve balance, and it costs nothing to set up beyond confirming your bank actually offers it.

Some contracts carry restrictions on which vendors or subcontractors you can pay, tied to security clearance requirements, country-of-origin rules, or specific procurement regulations, and keeping payables for a restricted contract in its own account makes it easier to confirm every payment against the applicable restrictions before it goes out, rather than reviewing a blended payables list after the fact. A single restricted payment made in error, even an honest administrative mistake, can create real compliance exposure on a federal contract.

A new contract vehicle, or a first award from an agency you haven't worked with before, can carry a meaningfully different payment cadence than what you're used to, and assuming it will match your existing contracts' timeline is a common and avoidable mistake. Treat every genuinely new contract type as its own data point for the first year, sizing its reserve conservatively until you have real payment history to replace the assumption.

A DCAA-compliant contractor typically bills using provisional indirect rates throughout the year, then reconciles to actual rates at year-end, and if your actual indirect costs ran higher than the provisional rate assumed, that true-up can mean owing money back rather than collecting more. Track your provisional-versus-actual indirect rate gap throughout the year rather than waiting for the year-end reconciliation to reveal it, so a true-up doesn't land as an unplanned cash outflow right when the contractor is also closing out the year's other obligations.

Small business subcontracting plan requirements on many federal contracts can also shape which vendors you're able to use, since a prime contractor is often required to direct a specific share of subcontracted work to small, disadvantaged, or otherwise designated businesses. Factor that requirement into vendor selection and payables planning early in a contract's life, rather than discovering late that your preferred vendor doesn't count toward a compliance target you're contractually obligated to hit.
