Government Contract Bid and Proposal Compliance Checklist: A Practical Checklist

Summary. A federal proposal is a compliance document before it is a sales document, and the failures that eliminate an offeror are rarely about the technical approach — they are missing certifications, a size representation that does not survive an affiliation analysis, an unaddressed organizational conflict of interest, a proposal that does not follow the solicitation's instructions, or a debriefing request filed a day late. This checklist runs the sequence from solicitation review through post-award: the bid decision, current registrations and representations, size and affiliation, teaming and subcontracting, proposal controls, pricing and cost data, clause review, and the jurisdictional debriefing and protest deadlines.

What this checklist is for. Preparing and submitting a compliant federal proposal, and preserving post-award rights. For the framework, see Government Contracting Basics: The FAR, Bid Protests, and Compliance Obligations.

Phase 1 — Read the solicitation on day one

Read Section L (instructions to offerors) and Section M (evaluation factors) first, and build a compliance matrix mapping every requirement to where in the proposal it is addressed.
Read Section C (statement of work) against the company's actual capability.
Note the contract type — firm-fixed-price, cost-reimbursement, time-and-materials, IDIQ — and what it requires (a cost-reimbursement award requires an accounting system determined adequate by DCAA).
Note the set-aside status and the NAICS code and size standard assigned.
Identify every deadline: questions, proposal due date and time, and any oral presentation.
Identify any defect apparent on the face of the solicitation — an ambiguity, an evaluation factor that appears to favor an incumbent, an unduly restrictive requirement. A patent defect not raised before the close of bidding is waived under Blue & Gold Fleet, L.P. v. United States, 492 F.3d 1308 (Fed. Cir. 2007).
Submit questions during the Q&A window, in writing, which both clarifies the record and preserves challenges.
Track amendments and acknowledge each one in the proposal — failure to acknowledge a material amendment renders a bid nonresponsive.

Why this matters. The two most common self-inflicted losses are a proposal that does not follow Section L's format and page limits, and a solicitation defect nobody raised before proposals were due.

Phase 2 — The bid/no-bid decision

Confirm the company qualifies — size, set-aside eligibility, required certifications, past performance relevance, and any facility clearance requirement.
Assess incumbency and whether the requirement is genuinely competed.
Assess capture position — was the company engaged before the solicitation, through sources sought responses, capability statements, or industry days?
Price the bid and proposal cost, which for a substantial procurement is significant and which is an indirect cost subject to allowability limits.
Confirm the company can perform at a price that is competitive and profitable.
Decide, and document the decision.

Phase 3 — Registrations, representations, and eligibility

Confirm SAM registration is active and not expiring before award, with a current Unique Entity Identifier.
Confirm the annual representations and certifications are current and accurate, and review them line by line rather than rolling them forward — false certifications are a False Claims Act exposure.
Confirm the NAICS code the solicitation assigns and the corresponding size standard, and verify the company qualifies.
Run the affiliation analysis: common ownership, common management, identity of interest among family members, newly organized concern, economic dependence, and the ostensible subcontractor rule under which a subcontractor performing the primary and vital requirements makes the prime a joint venturer. Size includes affiliates.
Confirm socioeconomic certifications — 8(a), HUBZone, service-disabled veteran-owned, women-owned — are current and supportable.
Confirm compliance with limitations on subcontracting for a set-aside award, generally 50 percent of the amount paid for services and supplies, with different rules for construction.
Screen the entity and its principals for exclusion in SAM.
Confirm facility and personnel clearances where required.
Confirm compliance with Section 889 prohibitions on covered telecommunications equipment and services.

Phase 4 — Teaming, subcontracting, and conflicts

Paper any teaming agreement before proposal work begins, addressing exclusivity, work share, proposal cost, proprietary information, and — critically — whether it is enforceable at all, since many teaming agreements are agreements to agree.
Confirm the work share is consistent with the prime's size representation and with the limitations on subcontracting.
Prepare the small business subcontracting plan where required, with realistic goals and a documented basis.
Analyze organizational conflicts of interest — unequal access to non-public information, biased ground rules, and impaired objectivity — and disclose and propose mitigation where any exists. An unaddressed OCI is a common and avoidable elimination.
Confirm compliance with the Procurement Integrity Act: no contractor bid or proposal information or source selection information obtained improperly, and no post-employment restriction violated by a recently hired former official.
Confirm flow-down clauses are included in subcontracts, and that subcontractors can comply with them — cybersecurity, labor standards, and domestic preference clauses are the ones subcontractors most often cannot meet.

Phase 5 — Prepare the proposal

Follow Section L exactly — format, font, margins, page limits, file naming, and submission method. Non-compliance is a basis for rejection and requires no explanation.
Address every evaluation factor in Section M, in the order and with the emphasis the solicitation assigns.
Ensure traceability: every requirement in the compliance matrix maps to a specific proposal location.
Assemble past performance references that are recent, relevant, and reachable, and notify each reference in advance.
Review CPARS ratings and address any negative rating proactively, with the corrective action taken.
Confirm every representation and certification in the proposal is accurate as of submission.
Run a compliance review by someone who did not write the proposal, against the matrix.
Run a color team review appropriate to the size of the pursuit.
Mark proprietary information with the legend the FAR prescribes, and understand the limits of that protection.
Submit early. Late is late, and the exceptions are narrow.

Phase 6 — Pricing and cost data

Build the price from a documented basis of estimate for every element.
Confirm the indirect rate structure and that unallowable costs under FAR Part 31 are excluded from the pools.
Where certified cost or pricing data is required — a negotiated contract above the threshold with no exception for commercial items, adequate price competition, or prices set by law — confirm the data is accurate, complete, and current as of the agreement date, and that the certificate is supportable. Defective pricing claims arise years later.
Where an exception applies, document it.
For services, anticipate a price realism or cost realism analysis and support labor rates and hours, because an unrealistically low price is a basis for elimination as well as for a protest.
Confirm labor category qualifications for every proposed person, because billing an unqualified person at a category rate is a false claim.
Confirm compliance with the Service Contract Act or Davis-Bacon wage determinations where applicable, and that the price reflects them.

Phase 7 — Award, debriefing, and protest

On notice of award or exclusion, request a debriefing in writing within 3 days. The request is short, it is the only way to learn the evaluation rationale, and it starts a different protest clock.
For a Department of Defense procurement, use the enhanced debriefing process to submit written questions, which extends the debriefing period and the protest clock.
Calendar the protest deadlines immediately. A protest of a solicitation impropriety apparent on the face must be filed before the time set for receipt of proposals. Any other protest must be filed within 10 days of when the basis was known or should have been known, or within 10 days after a required debriefing.
To obtain the CICA automatic stay of contract performance, file at GAO within 10 days after award or within 5 days after a required debriefing, whichever is later. Missing the stay deadline makes winning the protest largely academic.
Assess standing (interested party) and prejudice (a substantial chance of award but for the error) before filing.
Choose the forum — agency, GAO, or the Court of Federal Claims — with the stay, the timeline, and the standard of review in mind.
Whether or not a protest is filed, debrief internally: what the evaluators said, what to change, and which capture activities to start earlier next time.

Common mistakes

Reading the solicitation late, and losing the ability to challenge a patent defect.
Rolling forward the representations and certifications without review.
A size representation that fails an affiliation analysis, which is a False Claims Act and criminal exposure, not merely an eligibility problem.
Failing to acknowledge an amendment.
Ignoring Section L's format requirements.
An unaddressed organizational conflict of interest.
Past performance references that are stale, irrelevant, or unreachable.
A teaming agreement that is unenforceable, or a work share inconsistent with the size representation.
Requesting the debriefing late, or not at all.
Missing the five-day post-debriefing window for the automatic stay.
