1. Starting with a contract that's too big
It's tempting to go after the biggest opportunity you're eligible for — bigger contract, bigger payoff. But federal evaluators weigh past performance heavily, and if you have zero federal contracting history, you're competing against businesses that do. A $9 million contract with no track record behind you is a much harder win than a $90,000 contract where your qualifications clearly match the scope. Your first award matters less for its size and more for what it becomes: a documented, verifiable past-performance reference for every bid after it.
2. Treating the proposal like a sales pitch instead of a compliance document
Commercial sales writing tends to lead with persuasion — why choose us, what makes us different. Federal proposals are scored differently: evaluators are typically working from a structured scoring sheet tied directly to the solicitation's stated requirements. If a solicitation asks for five specific things and your proposal doesn't clearly address all five in a way that's easy to find, you can lose points even if your business is genuinely the best fit. Read the solicitation's evaluation criteria first, and structure your response to mirror it point for point — don't make the evaluator hunt for how you meet each requirement.
3. Missing the small details that trigger disqualification
Federal solicitations often include formatting requirements — page limits, font size, required attachments, specific document naming conventions — that have nothing to do with the quality of your work and everything to do with administrative compliance. Some contracting officers will disqualify a technically excellent proposal for missing a required certification page or exceeding a page limit by one line. Before you submit anything, go through the solicitation's instructions section as a literal checklist, not a suggestion.
4. Not asking questions during the Q&A period
Most solicitations include a formal window where bidders can submit written questions to the contracting officer, and the answers get published to everyone. Many first-time bidders skip this, either because they don't notice the deadline or assume asking questions signals weakness. In practice, the opposite is true — contracting officers regularly clarify ambiguous requirements in these Q&A rounds, and skipping it means you might build your entire proposal on a misreading that a thirty-second question would have fixed.
5. Waiting until the deadline is close to start
Federal proposals take longer to assemble than most first-time bidders expect, especially once you factor in required certifications, past-performance write-ups, and pricing documentation. Deadlines are also unforgiving — SAM.gov and most agency portals will not accept a late submission, no matter the reason. A contract with 12 days left to apply might sound like plenty of time until you're three days from the deadline and still waiting on a signed subcontractor agreement. Start the same week you find a contract that fits, not the week it's due.
Finding contracts worth this effort
All five of these mistakes assume you've already found a contract worth pursuing — which, as we've written about elsewhere, is its own challenge on SAM.gov. SetAsideScout handles that first step: it matches you to live opportunities in the set-aside programs you actually qualify for, so the time you put into avoiding these five mistakes goes toward a bid that was worth bidding on in the first place.
