Any business meeting minimum eligibility can bid on a federal contract. The obstacle isn't legal — it's understanding the process. This guide walks you through it in order, from SAM.gov registration and your UEI to submitting a compliant technical and price proposal before the deadline.

Any business can walk this path — even on the first try
Registration in the System for Award Management (SAM.gov) is mandatory before you can be awarded a U.S. federal contract — and it's free. Registering issues your Unique Entity ID (UEI), the 12-character code that replaced the DUNS number in 2022, and you'll also want a CAGE code. Budget 10-15 business days, complete your Representations & Certifications during signup, and set a reminder to renew every 365 days or your registration lapses.
Open opportunities are posted on SAM.gov's Contract Opportunities. Filter by your NAICS code (which also sets the small-business size standard) and by set-aside — Total Small Business, 8(a), WOSB, SDVOSB, or HUBZone. Buys above the Simplified Acquisition Threshold (currently $350,000) are fully competed; below it, agencies use lighter procedures. Save your searches and turn on alerts so new notices reach you automatically.
A federal solicitation isn't one document. Read the SF-33 cover, the Statement of Work (SOW) or Performance Work Statement (PWS), and above all Section L (proposal instructions) and Section M (evaluation factors). Section M tells you exactly how you'll be scored — Lowest Price Technically Acceptable (LPTA) or best-value tradeoff — and whether it's an RFP, RFQ, or IFB. Make the bid / no-bid call before you invest a single hour writing.
Typical requirements: a Capability Statement, past performance references (agencies also pull your record from CPARS), key-personnel resumes, your active SAM.gov registration, Reps & Certs, a bid bond if required, and — for architect-engineer work — an SF-330. Missing or expired documents are one of the most common ways a capable bidder gets eliminated on a technicality.
This is the decisive volume, and it must answer Section M point by point — evaluators score what's written, not what you meant. This is where Nomos comes in: from the solicitation PDF it maps the evaluation factors and drafts a technical proposal that addresses each one, grounded in your past performance and methodology. What used to take weeks resolves in hours.
Price realistically: figures that are unbalanced or far below cost can get your proposal deemed risky or your firm found non-responsible. Break out labor, materials, and any option periods exactly as Section L requires. On best-value procurements price is weighed against your technical score — the cheapest bid doesn't automatically win.
Federal deadlines are strict; a late proposal is almost always rejected, no exceptions. Submit through the method the solicitation specifies (SAM.gov or the agency's portal) and confirm receipt. Recommendation: upload at least 24 hours early to leave margin for portal glitches, file-size limits, or a last-minute question to the contracting officer.
How much does it cost to bid on a government contract?
Bidding is free — SAM.gov registration costs nothing and you never pay to submit. The real costs are the time to write a compliant proposal, a bid or performance bond if the solicitation requires one (often a percentage of the contract value), and optionally tools like Nomos to speed up drafting. Beware third-party sites that charge to 'register' you on SAM.gov; the official site is free.
Can a sole proprietor or very small business bid?
Yes. Federal law deliberately reserves a share of contracting for small business, and many solicitations are set aside exclusively for small, women-owned (WOSB), service-disabled veteran-owned (SDVOSB), HUBZone, or 8(a) firms. Your NAICS code determines the size standard that defines 'small' for a given opportunity. Being small is often an advantage here, not a barrier.
What if I have no demonstrable past performance?
It's not necessarily disqualifying. Some solicitations set low past-performance thresholds or accept references from commercial work, and a bidder with no record is often rated 'neutral' rather than negative. You can also team up — bid as a joint venture or as a subcontractor to an experienced prime — to borrow the past performance you don't yet have. Once you win, your performance is recorded in CPARS and builds your future record.
How much time do I have from posting to the deadline?
It varies by procedure. For competitive procurements above the Simplified Acquisition Threshold, agencies typically allow 30-60 calendar days, though it can be shorter for simplified or urgent buys. The exact due date and time are in the solicitation and on the SAM.gov notice — always work to that, and mind the time zone.
What happens if I make a mistake in a document?
It depends on the mistake. A contracting officer can let you correct a minor informality — a missing signature or date, an obvious clerical error — usually within a short window. What you generally cannot change after the deadline is your technical approach or your price. That's why submitting early, with a checklist against Section L, matters so much.
