The 5 Most Common Mistakes Small Businesses Make on Government Proposals

Government proposal evaluators read hundreds of submissions. After a while, the losing patterns become very familiar. Most small businesses — especially those new to government contracting — make the same avoidable mistakes that immediately signal to evaluators that the offeror doesn't understand the process.

Here are the five most common ones, and exactly how to fix them.

Mistake 1: Ignoring Section M Until the End

Section M of the solicitation lists the evaluation factors — the specific criteria the government will use to score your proposal. Many first-time proposers read the Statement of Work (Section C) first, write a response, and then check Section M as an afterthought.

This is backwards. Section M is the most important document in the solicitation.

Why it matters: Evaluators score proposals against Section M criteria, not against how impressive your solution sounds in the abstract. If Section M says "Technical Approach (40%), Past Performance (30%), Management Approach (20%), Price (10%)" and your proposal has four pages of pricing but half a page of past performance, you've prioritized exactly wrong.

The fix: Read Section M first. Write each section of your proposal specifically to address each evaluation factor. Use the evaluators' own language from Section M — if they say "demonstrated experience with cloud infrastructure," use that phrase in your proposal when describing your experience.

Mistake 2: Being Generic About Technical Approach

The technical approach section is where most proposals lose. Small businesses often describe their capabilities in general terms ("Our experienced team will leverage best practices...") without demonstrating that they specifically understand this contract's requirements.

Evaluators see hundreds of proposals that all sound the same. They're looking for evidence that you've read and understood their specific problem.

Why it matters: A generic technical approach suggests you're submitting a recycled proposal, not a thoughtful response to this specific opportunity. It signals risk to evaluators who need confidence you can actually execute.

The fix: Reference the RFP directly. Name the specific deliverables from Section C. Show that you understand the constraints and challenges the agency faces. Include a realistic schedule that maps to the performance period. Describe your approach to the specific technical challenges called out in the solicitation — not just your general methodology.

Mistake 3: Underestimating the Importance of Format Compliance

Section L of the solicitation (Instructions to Offerors) specifies exactly how your proposal must be formatted: page limits, font size, margin requirements, volume structure, and submission method. New proposers often read these requirements but don't take them seriously.

They should.

Why it matters: Proposals that exceed page limits can be disqualified before they're even read. Proposals that are missing required sections may be marked non-compliant. Even proposals with the wrong font or margins can create a negative impression — it signals carelessness.

The fix: Create a Section L compliance checklist before you start writing. List every formatting requirement and check each one off as you finalize your proposal. Do a final page count before submitting. Use a compliant template from the start rather than reformatting at the end.

Mistake 4: Submitting Weak or Irrelevant Past Performance

Past performance evaluation is where many small businesses lose — not because they have bad history, but because they document it poorly or select the wrong examples.

Common problems include: citing commercial clients (government evaluators can't verify these), choosing past work that's only vaguely related to the current opportunity, or writing past performance descriptions that are so vague they provide no useful signal to evaluators.

Why it matters: Past performance is often weighted 20–40% of the total evaluation score. Weak past performance documentation effectively caps your proposal score before the technical evaluators even weigh in.

The fix: For each past performance entry, include: the contract number, agency or client name, dollar value, period of performance, your specific role, and a concrete description of outcomes. Choose examples that are as similar as possible to the current requirement — same type of work, similar scale, similar technical environment. If you have government references available, they're far more credible than commercial ones.

Mistake 5: Treating Price as an Afterthought

Many small businesses either underestimate pricing (trying to "buy" their way into a contract) or submit price without enough analysis. Both are mistakes.

Pricing too low is actually a disqualifier in many evaluations — a price that seems unrealistically low triggers questions about whether you actually understand the scope of work. Pricing too high, without adequate justification, makes you easy to eliminate when competing against technically comparable proposals.

Why it matters: Even in "best value" evaluations (where price isn't the only factor), price analysis is a formal part of the evaluation. Contracting officers must determine that your price is fair and reasonable. If they can't make that determination, your proposal may be disqualified.

The fix: Build your price from a detailed work breakdown structure. Know your labor categories, hourly rates, overhead, and profit margins. Be prepared to explain and justify your pricing if asked. Research what similar contracts have paid in the past — USASpending.gov shows actual contract award amounts that you can use as benchmarks.

One More Thing: Follow the Instructions

This sounds obvious, but it's the root cause of most proposal failures. The government has published detailed instructions for exactly how to respond. Following them precisely — not approximately, not mostly — is the most basic thing you can do to stay in the running.

Proposals are eliminated at every stage of the evaluation process. Making it past format review, past technical evaluation, and into the final competitive range is an accomplishment. The businesses that do it consistently are the ones who read every word of the solicitation before writing a single word of their proposal.

GovRFP's AI compliance matrix automatically extracts every "shall" from your RFP and tracks which ones your proposal has addressed — eliminating the most common cause of non-compliance findings.
