Sole-source contract eligibility checklist

The 15-gate checklist that confirms whether your 8(a), HUBZone, SDVOSB, or WOSB firm is actually eligible for a sole-source set-aside award, certification, SAM, size, NAICS, ownership, thresholds, and permissibility, before you spend a month chasing one the rules require to be competed. CC Sole-Source Contract Eligibility Checklist

Why small-business firms need a sole-source eligibility checklist

A sole-source set-aside award is the closest thing to a clean win in federal contracting. No competition, no proposal war, a faster path to a signed contract, and an agency that already decided it wants your firm to do the work. For an 8(a), HUBZone, SDVOSB, or WOSB firm, it is the reason the certification was worth the paperwork in the first place. The problem is that “the agency wants us” and “we are eligible to receive it” are two different things, and the gap between them is where firms get hurt.

Here is how it goes wrong. A business development lead hears about a requirement that fits the firm perfectly. The contracting officer is open to a sole-source route. Everyone gets excited, capability statements fly, and three weeks later the award stalls because the firm’s certification lapsed last month, or its SAM.gov registration went inactive, or the NAICS code on the requirement carries a size standard the firm quietly grew past. None of that is fraud. It is a piece of eligibility that nobody was watching going dark at the exact moment it mattered most.

The other failure mode is chasing a sole-source award the firm was never going to get, or accepting one that should have been competed. Sole-source authority is not unlimited. Each program has its own rules for when an award can skip competition, and some of those rules turn on a dollar threshold and on whether the agency could reasonably expect competition among eligible small businesses. Spend a month positioning for a sole-source deal that the rules require to be competed, and you have spent a month for nothing.

Eligibility for a sole-source set-aside award is not one fact. It is a stack of them that all have to be true on the day of award: an active certification, a current SAM registration, a size that fits the procurement’s NAICS code, ownership and control that still meet the program, and for 8(a), a requirement SBA actually offered to and accepted into the program. This checklist lays that stack out so the answer to “are we eligible for this one” is something you confirm before you chase it, not something you discover after the agency has already moved on.

Who this checklist is for

• 8(a) program participants evaluating whether a requirement can come to them sole-source and whether their firm still meets every program condition on the day of award
• HUBZone certified firms confirming principal-office and employee-residency status hold before pursuing a HUBZone sole-source opportunity
• SDVOSB and VOSB firms checking that ownership, control, and verification status support a service-disabled-veteran sole-source award
• WOSB and EDWOSB firms verifying certification and eligibility for women-owned sole-source awards in qualifying industries
• Business development and capture leads at small federal contractors who position for sole-source work and need to qualify an opportunity before the firm commits time to it

The 15 eligibility gates

This checklist covers 15 eligibility gates a small-business firm should confirm before pursuing or accepting a sole-source set-aside award. Work it top to bottom against a specific opportunity. Every gate is a thing that has to be true on the day of award, and several of them are things that quietly lapse between awards, so confirm each one against the current opportunity rather than assuming last quarter’s status still holds.

1. Current, active certification in the relevant program. The firm has to hold an active certification in the program the award runs under, 8(a), HUBZone, SDVOSB, or WOSB/EDWOSB, at the time of award, not just at some point in the past. Certifications expire, get suspended, or lapse during annual review, and an award made while a certification is inactive is exposed. Confirm the firm’s status in the relevant SBA system reads active for the exact program the sole-source authority rests on before pursuing the opportunity.
2. Active SAM.gov registration. The firm must have a complete, active registration in SAM.gov, because an inactive or expired registration can stop an award cold regardless of how well the firm fits the work. SAM registrations expire annually and require renewal, and the lapse is silent, so a firm can be eligible on every other front and still be blocked here. Check the registration’s active status and expiration date early, since renewal can take time you may not have.
3. Business size within the size standard for the NAICS code. The firm has to be small under the size standard tied to the NAICS code assigned to the procurement, which is what makes it eligible for a small-business set-aside at all. Size is measured by the standard for that specific NAICS code, usually an average annual receipts figure or an employee count, so a firm small for one code can be other than small for another. Confirm the firm fits the size standard for the procurement’s actual NAICS code, and see 13 CFR part 121 for how size is calculated.
4. Correct NAICS code assigned to the requirement. The NAICS code the contracting officer assigns to the requirement drives the size standard and therefore who is eligible, so confirm the assigned code actually fits the principal purpose of the work. An incorrectly assigned NAICS code can change the size standard and shift eligibility, and there is a process to challenge an assignment you believe is wrong. Verify the code matches the work before you rely on the size determination that flows from it.
5. Ownership and control requirements still met. The program’s ownership and control conditions that qualified the firm in the first place have to still hold at the time of award, with no lapse. For each program the rules differ, unconditional ownership and control by disadvantaged individuals for 8(a), by a service-disabled veteran for SDVOSB, by women for WOSB, but the common thread is that a change in ownership, management, or control can quietly break eligibility. Confirm nothing has shifted, and check the program’s requirements in 13 CFR parts 124, 125, 126, or 127 as applicable.
6. For 8(a): the requirement was offered to and accepted into the 8(a) program. An 8(a) sole-source award generally requires that the procuring agency offer the requirement to SBA for the 8(a) program and that SBA accept it on the firm’s behalf. This offer-and-acceptance step is a defining feature of how 8(a) sole-source awards are made, and a firm cannot simply receive an 8(a) sole-source contract without it. Confirm the requirement has actually been offered to and accepted by SBA for the 8(a) program, and see 13 CFR 124.501 through 124.503 for the mechanics.
7. Sole-source dollar threshold for the program and industry not exceeded. Sole-source authority for set-aside programs is generally capped by a program- and industry-specific dollar threshold, above which the procurement may have to be competed rather than awarded sole-source. The exact figures differ by program and by whether the work is manufacturing or other, and they are adjusted over time, so do not carry a number from memory. Confirm the current applicable threshold for this program and this requirement in the relevant CFR part and in the solicitation before assuming a sole-source route is available.
8. Sole-source is actually permissible, not forced into competition. Even inside a set-aside program, a sole-source award is only available when the conditions for one are met, and a requirement that would draw competition among eligible firms may have to be competed instead of sole-sourced. The contracting officer’s judgment about whether two or more eligible firms would submit offers at a fair market price, the logic behind the small-business “rule of two,” can be the difference between a sole-source path and a competed one. Confirm sole-source is genuinely available for this requirement rather than assuming it because the firm is certified.
9. For HUBZone: principal office and employee-residency tests met. A HUBZone firm has to maintain its principal office in a HUBZone and meet the requirement that a qualifying share of its employees reside in a HUBZone, and both conditions have to hold for eligibility. These are the conditions firms most often drift out of as offices move and staff turn over, and they are checked at points that matter for an award. Confirm the principal-office location and the employee-residency percentage still qualify, and see 13 CFR part 126 for the current standard.
10. Fair-market-price determination is supportable. A sole-source award still requires that the price be determined fair and reasonable, so the firm’s proposed price has to be defensible rather than simply accepted because there was no competition. The contracting officer needs a basis to find the price fair, and a price that cannot be supported can stall or unwind an otherwise eligible award. Be ready with the cost and pricing backup that lets the contracting officer make and document a fair-market-price determination.
11. Firm not graduated, exited, suspended, or debarred. The firm has to still be a current participant in the program, not graduated or exited from 8(a), and it cannot be suspended, proposed for debarment, or debarred, which an active exclusion in SAM would show. An exclusion or a program exit removes eligibility regardless of how well the firm fits the work. Check SAM for active exclusions against the firm and its principals, and confirm the firm’s program participation is current and in good standing.
12. Limitations on subcontracting and performance-of-work plan in place. A set-aside award carries limitations on subcontracting that require the firm to self-perform a minimum share of the work, so the firm should have a realistic plan to meet that performance-of-work requirement before it takes the award. A firm that cannot actually self-perform the required share has a compliance problem waiting at the end of the job. Confirm the firm can meet the applicable limitation, and see 13 CFR 125.6 and the contract clause for the requirement that applies to this contract type.
13. Required representations and certifications current. The firm’s representations and certifications, including its SAM reps and certs and any program-specific certifications the award depends on, have to be current and accurate as of the award. Stale or inaccurate reps and certs can undermine an award even when the underlying facts would have supported it. Review the firm’s reps and certs for currency and accuracy before the award rather than after a problem surfaces.
14. No affiliation problems that bust the size standard. Even a firm that looks small on its own can be other than small once affiliation is counted, because SBA’s size rules add the receipts or employees of affiliated concerns to the firm’s own. Relationships through common ownership, management, joint ventures, or certain contractual ties can create affiliation that pushes a firm over the size standard for the NAICS code. Confirm there are no affiliation issues that change the size answer, and see 13 CFR part 121 for how affiliation is determined.
15. Documentation package assembled to support the sole-source justification. The agency needs a record that supports the sole-source award, so the firm should have its certification letters, capability statement, and relevant past performance ready to help the contracting officer build and document the justification. A clean, complete package makes the firm easy to award to and a thin one creates delay. Assemble the supporting documentation in advance so the agency has what it needs to justify the award without chasing the firm for it.

How to use the checklist

Run this against a specific opportunity, not in the abstract. Start at the top with the four gates that block awards most often and are fastest to check: active certification, active SAM registration, size within the NAICS-code standard, and the correct NAICS code on the requirement. If any of those is off, fix it or walk away before you invest capture time.

Then work the program-specific gates for whichever certification the award runs under, the 8(a) offer-and-acceptance step, the HUBZone office and residency tests, ownership and control, and the dollar threshold and sole-source-permissibility questions. Treat anything you cannot confirm as a hard stop until you have checked it against the current CFR and the solicitation, especially the dollar thresholds, which change.

Re-run the checklist close to award, not just when the opportunity first appears. Certifications, SAM status, and reps and certs lapse silently between the day you start chasing a deal and the day it would be awarded, so the only status that counts is the one on the day of award.

Keep every piece of your eligibility audit-ready

Sole-source eligibility is a stack of facts that all have to be true on the day of award, and most of them, certification status, SAM registration, size and NAICS, reps and certs, lapse silently between awards. Contracts Connected’s compliance dashboard keeps your certifications, SAM status, size and NAICS posture, and reps and certs tracked in one place with alerts before anything expires, so a lapse never costs you a sole-source award. The checklist tells you what to confirm. CC keeps it current so the answer to “are we eligible for this one” is already yes.
