Government Contracting Guide · Proposals
Write for the person holding the score sheet.
Sealed bids, best value, Sections L and M, and a review that catches mistakes.
Government proposal writing is about making an evaluator’s job easy: answer every requirement in the order it is scored, back each claim with proof, and submit a clean, compliant package on time.
Sealed bids and negotiated proposals
Governments pick winners in two main ways. In sealed bidding, used often for construction and simple purchases, the award goes to the lowest-priced bidder whose bid follows the rules and who can do the work, the lowest responsive, responsible bidder. In negotiated procurements, evaluators score the technical approach, management plan, past performance and price. Some use a best-value tradeoff, where a stronger proposal can win at a higher price; others use lowest price technically acceptable, where every proposal that meets the bar competes on price alone. The solicitation tells you which method applies, and it should shape how you write.
How winners are chosen
| Method | Who wins | Where to focus |
|---|---|---|
| Sealed bid | Lowest responsive, responsible bidder | Accurate price, every form complete |
| Best-value tradeoff | Best overall value; may cost more | Strengths that matter to the agency |
| Lowest price technically acceptable | Lowest price among acceptable proposals | Meet every requirement, sharp price |
Sections L and M, and the compliance matrix
Federal solicitations in the uniform contract format put the proposal instructions in Section L and the evaluation factors in Section M; state and local RFPs have their own versions. Before anyone writes, build a compliance matrix: a table listing every requirement, every “shall” and “must,” every page limit and format rule, where in your proposal each one is answered, and who is writing it. Outline your proposal in the same order and with the same numbering as the evaluation factors, so an evaluator can find each answer in seconds and give you credit for it.

The technical approach
The technical approach explains how you will do the work. Be specific: the steps, the schedule, the people and their roles, the tools, how you will measure quality, and how you will handle the risks that could go wrong. For each feature, state the benefit to the agency and the proof that you have done it before. Cut empty claims such as world class or best in the industry, which evaluators cannot score. Use headings that echo the requirements, short paragraphs, tables and one clear graphic where it helps, such as a timeline or an organization chart.
Past performance
Evaluators use past performance to judge how likely you are to succeed. Choose projects that are recent and similar in size, scope and complexity, and describe them with results in numbers: on time, on budget, response times, savings, satisfaction scores. Give references who will answer the phone. If you are new to government work, use subcontracts, commercial projects of similar size, and the experience of your key people, and explain clearly why it is relevant.
Price
Your price must be both competitive and realistic. Build it from your real costs, overhead and a fair profit, check it against past award prices for similar work, and make sure every line item the solicitation asks for is filled in. In best-value procurements, a price that is unrealistically low can count against you, because it suggests you do not understand the work.

The final review
Plan to finish a day early. Have someone who did not write the proposal score it against Section M as an evaluator would, and fix every weak spot they find. Then run a compliance check: every amendment acknowledged, every form signed, page limits and file names followed, price sheets complete. Late proposals are generally rejected, so submit early and save the confirmation.
Your proposal checklist
- DecideBid or no bid, in writing, with reasons.
- Build the matrixEvery requirement mapped to a section and a writer.
- Write to the scoreApproach, management, past performance, in the evaluation order.
- ReviewA fresh reader scores it against the criteria.
- Submit earlyForms signed, amendments acknowledged, confirmation saved.
After the award: debriefs
Win or lose, ask for a debriefing. Federal agencies must offer debriefs in many negotiated procurements when requested on time, and many state and local agencies will meet with you if you ask. Listen for how evaluators saw your strengths and weaknesses, and use it on the next bid.
Common reasons proposals lose
Most losing proposals are not badly written; they are hard to score. They answer requirements in a different order than the evaluation factors, bury key points in long paragraphs, repeat marketing language instead of specifics, or miss a required form or amendment. Others propose a solution the agency did not ask for, or a price that looks unrealistic. Read your draft as an evaluator with a score sheet would, and ask of every section: where is the requirement, where is our answer, and where is the proof?
Building a reusable proposal library
Save time on every future bid by keeping a library of approved content: company overview, resumes, project descriptions with results, quality and safety plans, management approach and standard forms. Update it after each bid with the best new material, and tailor each piece to the next solicitation rather than pasting it unchanged.

- Be specific: steps, schedule, people, risks and proof.
- Review with fresh eyes and submit a day early.
Frequently asked questions
What is the difference between a bid and a proposal?
A sealed bid is won on price by the lowest responsive, responsible bidder. A proposal is scored on approach, experience and price, and may be won on best value.
What is a compliance matrix?
A table that lists every requirement in the solicitation and shows where your proposal answers it.
What are Sections L and M?
In federal solicitations, Section L gives the proposal instructions and Section M gives the evaluation factors.
What if I have no government past performance?
Use subcontracts, similar commercial projects and your key people’s experience, and explain why they are relevant.
Can a late proposal be accepted?
Generally no. Submit early and keep proof of the time you submitted.
