10 Common Government Proposal Mistakes (And How to Avoid Them)

Evaluators reject or down-score most losing proposals for predictable, preventable reasons. Here are the ten we see most — roughly in order of how often they end a small business's bid.

Fatal compliance mistakes

• 1. Late submission — rejected with no exceptions, even for email delays. Fix: finish 48 hours early; submit 24 hours early.
• 2. Unacknowledged amendments — a missing acknowledgment can void an otherwise perfect bid. Fix: check SAM.gov for amendments the day before submission.
• 3. Missing required documents — unsigned forms, absent bonding letters, no certificates of insurance. Fix: build a submission checklist from the instructions section and assign every item an owner.
• 4. Format violations — exceeded page limits, wrong fonts, wrong volume structure. Evaluators may stop reading at the page limit. Fix: check Section L formatting rules before writing, not after.

Scoring mistakes

• 5. Ignoring Section M — writing what you want to say instead of what's scored. Fix: mirror the evaluation factors as your section headings.
• 6. Unanswered 'shall' statements — every requirement needs a response. Fix: build a compliance matrix and verify every row before submission.
• 7. Generic claims — 'extensive experience' and 'commitment to excellence' score poorly because evaluators can't defend them in writing. Fix: name contracts, give metrics, identify people.
• 8. Boilerplate that ignores this agency — evaluators recognize a template blast instantly. Fix: reference the agency's mission, facility, and PWS specifics throughout.

Business mistakes

• 9. Pricing against the market instead of the wage determination — Service Contract Act and Davis-Bacon rates are floors; pricing below them is non-compliant, pricing without them is unprofitable. Fix: build labor costs from the determination attached to the solicitation.
• 10. Bidding everything — the meta-mistake that causes the other nine by spreading your hours too thin. Fix: a disciplined bid/no-bid decision before any writing starts.

The pattern behind all ten

Almost every item on this list is mechanical, not creative: read the instructions, track the requirements, verify before submission. That's why a compliance matrix and a submission checklist — built the day the RFP arrives — prevent more losses than any amount of elegant prose. Compliance gets you evaluated; evidence gets you scored; only then does writing quality matter.
