Sole source is the sharpest tool in the SDVOSB toolkit
For an SDVOSB founder, the difference between competing for a contract and being awarded one without competition is operational. A sole-source award removes the proposal cost, the months of capture work, and the loss-rate uncertainty that come with full-and-open competition. The federal small business toolkit gives SDVOSBs explicit authority to receive sole-source awards under specific conditions — and the firms that understand those conditions and position for them win work the open market would never give them.
This is a primer on the FAR authorities, the J&A process, the dollar-threshold mechanics, and how to build the agency relationships that turn the authority into actual awards.
What FAR 6.302 actually says
FAR Part 6 establishes the legal framework for limiting sources on federal contracts. Most federal contracts must be competed under full-and-open competition. FAR 6.302 carves out seven exceptions where the contracting officer may award without full competition:
- 6.302-1: Only one responsible source — the requirement can only be met by one firm.
- 6.302-2: Unusual and compelling urgency — competition would harm the government's interests.
- 6.302-3: Industrial mobilization, engineering, developmental, or research capability or expert services — narrow specialty cases.
- 6.302-4: International agreement — terms of a treaty or international agreement.
- 6.302-5: Authorized or required by statute — Congress has authorized the sole-source action.
- 6.302-6: National security — disclosure of the requirement would compromise national security.
- 6.302-7: Public interest — the head of the agency has determined sole source is in the public interest.
For SDVOSBs, the relevant authority is 6.302-5, which incorporates the SDVOSB sole-source authority created by 15 U.S.C. § 657f. Under this authority, contracting officers may award sole-source contracts to qualified SDVOSB concerns when specific conditions are met — and they do, regularly.
SDVOSB sole-source thresholds
The SDVOSB sole-source authority is bounded by dollar thresholds set by the SBA. The thresholds vary by industry — manufacturing requirements have one threshold, services another. Both are adjusted periodically. Rather than memorize a number, anchor on the source: the current thresholds are published in 13 CFR 125.20 and reflected in agency-level guidance. Verify the current limits at sba.gov before pricing a pursuit, because the firm that prices to last year's threshold and discovers the requirement now exceeds it has misread the entire pursuit.
The conditions for sole source under this authority include: the contracting officer reasonably expects that the award price will not exceed the threshold; only one SDVOSB can perform the work; the award price is fair and reasonable; and the SDVOSB is responsible for the work.
The threshold is not a guarantee — it is a ceiling. The contracting officer must still document why the requirement fits sole source. That is where the J&A comes in.
The J&A process from the contractor's side
A Justification and Approval (J&A) is the document the contracting officer signs to award sole source. It explains why the requirement does not need full competition. The J&A is the contracting officer's document — but the SDVOSB's role in supporting it is what determines whether the J&A holds up.
A defensible J&A under SDVOSB sole-source authority typically establishes:
- The requirement is identified and well-defined.
- The SDVOSB has demonstrated capability to perform the work.
- The award price is fair and reasonable, supported by market research.
- The SDVOSB is the only known source that can perform the work at the price within the threshold.
The contractor's contribution to the J&A is primarily evidence. Capability documentation — past performance citations in the required NAICS, technical certifications, key personnel resumes, prior work product samples — gives the contracting officer the material to write the J&A. Pricing transparency — labor rates benchmarked against CALC+ or BLS data, with a clear basis for the proposed price — supports the fair-and-reasonable determination.
A weak J&A invites protest. A strong one rarely does. The contractor's job is to make the J&A easy to write and hard to challenge.
Building agency relationships that lead to sole-source actions
Sole-source awards do not appear out of thin air. The contracting officer needs to know the SDVOSB exists, needs to believe the SDVOSB can perform the work, and needs the requirement to fit the authority. Each of those preconditions requires upstream work.
Signals to watch and act on:
- Sources sought notices — the agency is asking who can perform a requirement. A capability statement response that demonstrates SDVOSB qualification puts the firm on the contracting officer's short list.
- Industry days — agencies hold these for upcoming requirements. Attendance signals interest. Substantive questions during Q&A demonstrate domain knowledge.
- RFI responses — agencies issue Requests for Information to refine requirements. A thoughtful RFI response can shape the requirement in ways that align with the responding firm's capabilities.
- Small Business Office contacts — every federal agency has a small business specialist whose job is to help small businesses access agency contracts. They are an underused resource.
What not to do: generic capability statements, unsolicited proposals, cold outreach to contracting officers without context. The contracting officer's time is finite; pitches without a hook waste it and damage the relationship.
When sole-source pursuits look like competed pursuits
Not every requirement that ends up sole-source begins that way. Sometimes the agency starts with a competed acquisition strategy and converts to sole-source mid-process — perhaps after a sources sought identifies only one qualified SDVOSB, or after a competitive solicitation receives only one responsive bid. Other times the agency uses a different authority entirely (6.302-1 only-one-responsible-source, for example, when the SDVOSB happens to also be the only responsible source).
Reading the solicitation language matters. A competed SDVOSB set-aside that says "the government anticipates competitive proposals" is one signal. A sources sought notice with a Statement of Work attached and a 10-day response window is another. Neither guarantees a sole-source outcome, but both tell the contractor where in the acquisition lifecycle the requirement actually sits.
How to position for sole source over the next 12 months
Sole-source pursuits are won upstream of the solicitation, not at proposal time. A 12-month positioning campaign typically involves:
- Quarter 1: Identify target agencies and requirements. Map your NAICS posture against agency spend patterns. Identify two or three target requirements likely to come to market in the next 12 months.
- Quarter 2: Build the relationship infrastructure. Attend industry days for target requirements. Submit substantive responses to sources sought. Schedule capability briefings with the small business specialist at each target agency.
- Quarter 3: Refine the capability documentation. Update past performance citations. Tailor capability statements to specific requirements. Identify teaming partners for any capability gaps.
- Quarter 4: Maintain the relationships. Follow up on sources sought responses. Attend follow-up industry days. Stay visible without being intrusive.
The discipline is patience. Sole-source awards rarely come to firms that surface a month before the requirement drops. They come to firms the contracting officer has been hearing about for months — through sources sought, industry days, the small business office, and occasional substantive contact.
