Bid/No-Bid Decisions for Small Defense Contractors
Most small contractors I work with do not have a bid/no-bid problem. They have a saying-yes problem.
The pattern is always the same. A solicitation shows up that is almost a fit. Somebody says “we should at least respond.” Three weeks later the owner, the capture lead and the two best engineers have burned most of a month on a proposal that was never going to win, and the work that would have won something got pushed. Then it happens again the next quarter.
I spent a career in the Signal Corps watching organizations confuse activity with progress. Bidding is the government contracting version of that. So this post is not a list of ten criteria. It is the handful of things that actually change the math for a firm under fifty people, with the numbers where numbers exist — and an honest admission where they do not.
Every proposal you lose comes out of this year’s profit
This is the part people intellectually know and emotionally ignore.
Bid and proposal cost is defined at FAR 31.205-18(a) as “the costs incurred in preparing, submitting, and supporting bids and proposals (whether or not solicited) on potential Government or non-Government contracts.” Paragraph (c) makes those costs allowable “as indirect expenses on contracts to the extent that those costs are allocable and reasonable.”
Indirect. That single word is the whole argument. B&P is never a direct charge to a contract. It rides in your G&A pool and gets recovered across your entire contract base. Which means:
- You fund every proposal out of this year’s margin.
- You recover it slowly, and only in proportion to how much contract volume you already have.
- There is no mechanism to recover the cost of a loss directly. FAR 31.205-18(d) allows deferred recovery of certain independent research and development costs in narrow circumstances. There is no equivalent for B&P.
So a large prime with a billion-dollar base absorbs a lost proposal as a rounding error. A ten-person shop with three contracts absorbs it as this quarter’s owner distribution. Same rule, opposite consequence. The FAR does not care that the recovery mechanism only works at scale.
I want to be straight about the evidence here. There is no credible published benchmark for what a proposal costs a small firm. I looked at GAO, SBA, DAU and the Federal Register and found nothing. The industry survey numbers that circulate come from vendor studies whose denominators are not stated, and everything else is consultant marketing. So do not let anyone sell you a “your B&P should be X percent of revenue” rule. Build your own number from your own timesheets for the last four proposals, wins and losses both. That number is real. The benchmark is not.
The most important variable is the one nobody publishes
Ask any experienced capture person what most determines whether you win, and they will say incumbency. Ask them for the number and the room goes quiet.
I could not find a single authoritative published figure on incumbent retention rates in federal recompetes. Not GAO. Not SBA. Not CRS. Not DoD. Every “incumbents win 70 percent of the time” claim I chased traced back to vendor marketing with no stated methodology.
That is worth sitting with. The single biggest call in your pipeline — do we go after work somebody else is already performing — is being made on anecdote across the entire industry, including by people far better resourced than you.
You do not need the statistic, though, because the mechanism is documented in the FAR itself. Which brings me to the part that actually explains incumbent advantage.
“Neutral” past performance is not parity
FAR 15.305(a)(2)(iv) says:
“In the case of an offeror without a record of relevant past performance or for whom information on past performance is not available, the offeror may not be evaluated favorably or unfavorably on past performance.”
New entrants read that as protection, and it is. GAO confirmed as recently as March 2026, in Bowhead Logistics Management, that an offeror without relevant past performance gets a neutral confidence rating and that neutral does not disqualify a proposal.
Here is the trap. Neutral protects you from being penalized. It does nothing to help you win.
In a best-value tradeoff, the source selection authority is deciding whether a technical or performance advantage justifies paying more. Your competitor arrives with Substantial Confidence built on directly relevant CPARS ratings. You arrive with an absence. Nothing was held against you, and nothing was available to weigh in your favor either. On the one factor most likely to justify a price premium, you have no discriminator at all.
That structural asymmetry — not any rule violation, not any bias — is the mechanism behind incumbent advantage. And it produces two concrete bid/no-bid rules:
- If you have no relevant past performance, a best-value tradeoff against an incumbent is your worst structural matchup. You are competing on the factors where you can only tie.
- Lowest-price technically-acceptable and set-aside competitions are where your neutral rating costs you the least. If price and acceptability decide it, an absent past performance record stops being the deciding variable.
Two things help. First, FAR 15.305(a)(2)(ii) requires solicitations to describe how offerors with no relevant history will be evaluated and to give you the chance to identify federal, state, local and private contracts for similar efforts. Read that paragraph in every solicitation — it is your opening. Second, Section 824 of the FY2026 NDAA expands acceptable past performance at DoD to include commercial and non-government projects. If your best evidence is commercial work, that provision is now your friend.
The threshold change most people missed
On October 1, 2025, the inflation adjustment to acquisition thresholds took effect, and it moved more than the usual rounding.
| Threshold | Was | Now |
|---|---|---|
| Micro-purchase | $10,000 | $15,000 |
| Simplified acquisition | $250,000 | $350,000 |
| Certified cost or pricing data (FAR) | $2M | $2.5M |
| Prime subcontracting plan | $750,000 | $900,000 |
| 8(a) sole-source justification required above | $25M | $30M |
Why the simplified acquisition threshold matters more than the others: FAR 19.502-2(a) says acquisitions above the micro-purchase threshold but not exceeding the simplified acquisition threshold shall be set aside for small business unless the contracting officer determines there is no reasonable expectation of offers from two or more responsible small businesses at competitive prices.
That automatic reservation band just went from $10,000–$250,000 to $15,000–$350,000. A meaningfully larger slice of federal buying is now presumptively yours — and it happens to be the lowest-B&P-cost work in the market, because simplified acquisition procedures do not demand a hundred-page proposal.
If your pipeline is all six-figure-and-up full-and-open pursuits, you may be ignoring the one band where the rules are actively tilted toward you.
You are bidding under a FAR that is not the published FAR
This one is easy to miss and it will confuse you at exactly the wrong moment.
The Revolutionary FAR Overhaul was implemented in its first phase through class deviations that replaced each FAR part, pending formal rulemaking. Twelve proposed rules were published on June 23, 2026, and comments closed July 23, 2026. As of today those are still proposed rules. The DFARS Overhaul did the same thing on its own track — class deviations effective February 1, 2026, with rulemaking to follow.
Practical consequences for a small bidder:
- Clause numbers in solicitations may not match what you find on acquisition.gov.
- The neutral past performance rule I quoted above lives at 15.305(a)(2)(iv) in the codified FAR and at 15.202(c)(1) in the deviation text. Substance unchanged, citation different. If you ever need to raise it, cite the right one.
- DFARS 252.204-7019 was deleted outright and 252.204-7020 was renumbered to 252.240-7997. If you are still using a proposal template that references 7019, it is citing a clause that no longer exists.
Add “verify every clause citation against the deviation text” to your proposal checklist. It is thirty minutes that prevents an embarrassing compliance matrix.
What the CMMC suspension did and did not change
On July 13, 2026 the Department of War suspended CMMC Phase II — the third-party C3PAO certification assessments that were to become a condition of award starting November 10, 2026.
If you have been avoiding CUI-bearing work because of the certification cost, the gate is off for now. What did not change:
- DFARS 252.204-7012 in full, including 72-hour incident reporting.
- All 110 NIST SP 800-171 Rev. 2 requirements.
- Self-assessments, SPRS score posting, and annual affirmation by a senior official.
- FAR 52.204-21 basic safeguarding for FCI.
- Every bit of your False Claims Act exposure.
The honest framing for a bid decision: CUI work got cheaper to bid, not cheaper to perform. And this is a suspension by memorandum pending a task force review with no announced rulemaking timeline. A five-year contract you sign this fall could see certification reimposed in year two. Price that risk rather than pretending it resolved.
Protesting is not a strategy, but the numbers are not what you think
From GAO’s FY2025 Annual Report to Congress:
| Metric | FY2025 |
|---|---|
| Cases filed | 1,688 (down 6%) |
| Merit decisions | 380 |
| Sustained | 53 |
| Sustain rate | 14% |
| Effectiveness rate | 52% |
The gap between those last two numbers is the interesting part. The sustain rate — GAO actually rules for you — is 14%. The effectiveness rate — you obtained some form of relief, usually because the agency took voluntary corrective action — is 52%. Most of the value in the protest system comes from agencies fixing things rather than GAO ordering them to.
The top three grounds for sustained protests in FY2025 were unreasonable technical evaluation, unreasonable cost or price evaluation, and unreasonable rejection of a proposal. Small businesses file between 62 and 73 percent of all protests. And at most 1.5% of DoD procurements drew a GAO protest at all between FY2020 and FY2024.
None of this makes protesting a business model. But if you lost on an evaluation that genuinely does not track the stated criteria, the odds of getting something are better than the headline sustain rate suggests.
Bid as a team when you cannot bid as a prime
Two mechanics worth knowing cold, because together they are the direct answer to the neutral-past-performance problem.
Limitations on subcontracting, FAR 52.219-14. On a set-aside you may not pay more than a set percentage of the amount the Government pays you to subcontractors that are not similarly situated entities: 50% for services, 50% for supplies other than from a nonmanufacturer, 85% for general construction, 75% for special trade construction. Note the base — it is a percentage of what the Government pays, not of total contract value. Work performed by a similarly situated entity (small, and holding the same set-aside status for that procurement) does not count against the limit. But anything that entity further subcontracts does count against yours, so you cannot launder it through a second tier.
SBA Mentor-Protégé, 13 CFR 125.9. A mentor-protégé agreement runs up to six years. The core benefit is in this sentence: “No determination of affiliation or control may be found between a protégé firm and its mentor based solely on the mentor-protégé agreement or any assistance provided pursuant to the agreement.” The joint venture can pursue any small business contract the protégé qualifies for, including set-asides.
That is the only mechanism that lets a fifteen-person firm prime work it could not staff, perform, or price alone — and it converts the mentor’s past performance into a discriminator you can actually use.
The automatic no-bids
These are not judgment calls. If any of these is true, stop reading the solicitation and go do billable work.
| Condition | Authority |
|---|---|
| SAM registration not active at offer submission | FAR 52.204-7(b)(1) |
| Claiming an SDVOSB, WOSB, 8(a) or HUBZone set-aside without SBA certification | FAR 19.14; 13 CFR 128 — SDVOSB self-certification ended for set-aside awards as of January 1, 2024 |
| NAICS size standard does not fit | 13 CFR 121 / FAR 19.102 |
| Cost-reimbursement work with no adequate accounting system | FAR 16.301-3(a)(3) |
| Cannot meet the 50/50/85/75 self-performance floor without similarly situated subs | FAR 52.219-14(c) |
| Recertified other-than-small after a transaction with a non-small entity | 13 CFR 125.12 |
The accounting system one deserves a sentence of its own, because it catches good firms. FAR 16.301-3(a) permits a cost-reimbursement contract only when, among other conditions, “the contractor’s accounting system is adequate for determining costs applicable to the contract or order.” Adequacy is normally demonstrated through a pre-award accounting system survey against SF 1408. If you have never been through one, budget two to four months and real money to get there before you bid cost-type work — not after you win it and discover you may be found non-responsible.
One piece of relief on that front: Section 1806 of the FY2026 NDAA raised the Cost Accounting Standards applicability threshold from $2M to $35M and full CAS compliance from $50M to $100M. CAS is largely no longer a small firm’s problem. The SF 1408 adequacy requirement is unchanged.
The decision, in one paragraph
Before you commit a single hour, answer four questions honestly. Do we clear every automatic disqualifier? Is there a specific, nameable reason a source selection authority would pick us over the incumbent — and is it a reason the stated evaluation criteria will actually let them act on? Can we fund the proposal out of this year’s margin without pushing revenue-generating work? And if we win, can we perform it with the people we have?
Four yeses and you bid. Anything less and the discipline of walking away is worth more than the lottery ticket. The firms I watch grow steadily are not the ones bidding the most. They are the ones that stopped bidding things they were never going to win, and spent the recovered hours on the work in front of them.
