How to bid on a federal contract: the seven steps, in order
Bidding on a federal contract is not a lottery — it is a documented process with a fixed order. Here are the seven steps, and the three points where most first-time bidders are eliminated before a single evaluator reads their technical volume.
The United States government buys roughly $750 billion of goods and services a year, and it is required to publish most of it. The barrier is almost never finding the work — it is surviving the administrative gauntlet that comes before anyone judges whether you are good at it.
1. Register in SAM.gov — before you need to
You cannot receive a federal award without an active registration in the System for Award Management. Registration issues you a Unique Entity ID (UEI), which replaced the DUNS number in 2022, and it must be renewed every twelve months.
2. Know your codes
Federal buyers classify what they buy with NAICS codes, and each code carries a small-business size standard — a revenue or headcount ceiling below which you qualify for set-aside competitions. Your codes decide which opportunities you can see and which ones you can win.
- Pick every NAICS code you can genuinely perform — not every one you could imagine performing.
- Check the size standard for each: the same company can be small under one code and large under another.
- Add your PSC (Product Service Code) — many buyers search by PSC rather than NAICS.
3. Find the right solicitations
Everything above the micro-purchase threshold is published on SAM.gov Contract Opportunities. Below it, buyers may use a government purchase card with no competition at all — which is why relationships with contracting officers still matter for small work.
| Notice type | What it means | What it asks of you |
|---|---|---|
| Sources Sought | Market research, no award | A capability statement. Low effort, high leverage. |
| RFI | Request for information | Your view on scope, timing, feasibility. |
| RFQ | Request for quotation | A price, usually against a fixed description. |
| RFP | Request for proposal | A full technical and price proposal, evaluated on stated criteria. |
4. Read the solicitation in the right order
A federal solicitation follows the Uniform Contract Format — Sections A through M. Reading it front to back is a beginner's error: the sections that decide whether you win come near the end.
- 1Section M first
Evaluation factors. This is how you will be scored. Everything you write should serve it.
- 2Then Section L
Instructions to offerors: page limits, fonts, volume structure, submission mechanics.
- 3Then Section C
The statement of work — what the government actually wants done.
- 4Then the rest
Clauses, deliverables, wage determinations, attachments.
A proposal that answers Section C beautifully and ignores Section M is a well-written losing bid. The evaluators score against M, and only against M.
5. Complete your representations and certifications
Your SAM.gov profile carries annual representations and certifications; individual solicitations add their own. These are legal attestations — on socioeconomic status, on lobbying, on supply-chain provisions such as Section 889. A single unchecked box makes an otherwise excellent bid non-responsive, and non-responsive bids are not read.
6. Write to the evaluation criteria
Under FAR Part 15, most negotiated procurements use a best value tradeoff: technical merit, past performance and price, weighted as the solicitation states. Read the weighting and let it dictate your page budget — if past performance is 40 % of the score, it deserves more than a paragraph.
- Mirror the government's own headings and numbering. Evaluators score with a checklist.
- Every claim needs evidence — a contract number, a measured result, a named reference.
- Past performance means relevant past performance: similar scope, similar size, recent.
7. Submit early, in the format demanded
Late is late. The FAR's late-proposal rule is applied strictly, and "the portal was slow" is not an exception. Submit a day early, then use the remaining time to improve — you can usually replace a submission before the deadline, but you can never make a late one count.

Frequently asked questions
How long does SAM.gov registration take?+
Plan for two to six weeks. Entity validation compares your legal name and address against incorporation records; any mismatch restarts the clock. Registration must then be renewed annually or it lapses.
Do I need past federal experience to win a federal contract?+
No, but you need relevant past performance — commercial contracts of similar scope and size count, and many solicitations say so explicitly. Subcontracting on a federal award first is the usual on-ramp.
What is the difference between an RFQ and an RFP?+
An RFQ asks for a price against a defined requirement and is usually awarded on price and technical acceptability. An RFP asks for a proposal evaluated on stated factors, most often a best value tradeoff between technical merit, past performance and price.
What makes a bid non-responsive?+
Anything that departs from the mandatory terms of the solicitation: a missing certification, an unsigned form, exceeding a page limit, or arriving after the deadline. Non-responsive bids are set aside before evaluation.
