Winning an award does not put money in your account. It creates a right to be reimbursed, or to draw down, against costs you have already incurred and can document. Founders who assume a lump sum arrives on the award date are the ones who miss payroll in month two. This is general information, not accounting advice; your CPA should confirm how any of it applies to your company.
Drawdown or invoice depends on the instrument
On a grant, funds are typically requested through an agency or Treasury payment system, and the mechanics differ between NIH, NSF, DOE, and other grant-making agencies. On a contract award, you submit invoices against the terms of the contract and they are reviewed before payment. Some contracts are cost reimbursement, some are firm fixed price paid against completed milestones, and a few use other arrangements entirely. The difference is not cosmetic: it changes what documentation you attach, how often you can ask for money, and how much scrutiny each request receives. Confirm which applies to you in writing, because the wrong assumption here is expensive.
The cash-flow gap nobody budgets for
Under cost reimbursement you spend first and get paid later. Between the pay period, the accounting close, the submission, agency review, and the payment run, a small company can easily wait several weeks from spending a dollar to seeing it again, and the first request of an award usually takes longest while your setup is verified. Plan working capital for that gap before you hire against the award. Founders often underestimate it in the same way they underestimate the hidden costs of hardware development, and the fix is the same: model the cash timing, not just the totals.
Front-loaded costs make the gap worse. If your plan buys long-lead equipment or pays a subcontractor early, that money leaves before any reimbursement arrives. Sequencing purchases deliberately is often the difference between a comfortable award and a stressful one, particularly if you are running without outside investment.
Claimed costs must match the approved budget
Every dollar you claim should map to a line in the budget the agency approved, supported by a timesheet, an invoice, or a receipt. Moving money between categories may be allowed within limits, may require prior approval, or may not be permitted at all, depending on the agency and the instrument; ask before you shift, not after. Costs that are unallowable, outside the period of performance, or unsupported get disallowed on review, and disallowed means you already spent it and will not be repaid. Many of these problems start with an unrealistic proposal budget, which is why the usual grant budget mistakes keep resurfacing months after submission.
Financial reporting frequency also varies: some agencies want a financial report annually, some at each payment request, some at closeout only. Note that reimbursement is not the same as tax treatment, which is a separate question worth understanding early.
