For service-disabled veteran-owned small businesses, sole-source contracts are one of the most valuable tools in federal contracting: an award without a full competition. But sole-source authority is not unlimited. Dollar thresholds, justification rules, and agency-specific authorities decide when a contracting officer can award directly to your firm. This guide explains the SDVOSB sole-source limits, how they differ at the VA, and what your firm can do to become the obvious sole-source choice.
What Is a Sole-Source Award?
A sole-source award is a contract awarded to one firm without soliciting competing offers. The government still has to determine that the price is fair and reasonable and document why competition was not used, but the winning firm does not have to beat other bidders on a scored proposal. For small firms, that removes the biggest cost and risk in federal contracting: writing a full competitive proposal against larger, more experienced rivals. Sole-source awards are especially useful for first-time federal contractors because they can create the past performance needed to win competitive work later.
Government-Wide SDVOSB Sole-Source Limits
Outside the VA, contracting officers may award sole-source contracts to verified SDVOSBs under FAR 19.14 when the anticipated value does not exceed the statutory thresholds: generally $4.5 million for most acquisitions and $7 million for manufacturing NAICS codes. These thresholds are set by statute and adjusted periodically, so always confirm the current figures before you rely on them in a conversation with a buyer. If the requirement exceeds the threshold, it generally must be competed among SDVOSBs or opened more broadly, unless another sole-source authority applies.
Several conditions must also be met: the firm must be verified as an SDVOSB at the time of award, the contracting officer must determine the firm is responsible, the price must be fair and reasonable, and the justification must be documented. A sole-source award is not a gift; it is a documented decision that the government can defend if it is questioned later.
Higher Limits at the VA Under Vets First
The Department of Veterans Affairs operates under separate Vets First authority, and its SDVOSB sole-source thresholds are higher than the government-wide limits. That is one reason the VA is such an important customer for veteran firms, as explained in our VA Vets First guide. VA contracting officers can award sole-source contracts to verified SDVOSBs at values that would require competition elsewhere, provided the justification supports it. If your firm serves healthcare, facilities, IT, or professional services markets, the VA’s higher thresholds make it the first agency to study.
When Is a Sole-Source Award Justified?
The most common justification is that only one responsible SDVOSB can perform the work. That might be because your firm holds a unique capability, proprietary technology, or specialized clearance; because continuity with an existing system or provider is essential; or because urgent and compelling circumstances leave no time for competition. Another path is when market research shows only one verified SDVOSB is capable and available at a fair price. Contracting officers document this reasoning in a justification and approval (J&A) or a sole-source determination, depending on the dollar value and the agency’s procedures.
Your job as a vendor is to make that justification easy to write. Document what makes your capability unique, keep past performance records that map directly to the requirement, and communicate early with the program office so the buyer understands your capability before the requirement is finalized. Firms that appear late, with a generic pitch, rarely become sole-source picks; firms that helped shape the requirement’s understanding often do.
What Sole-Source Does Not Mean
Sole-source does not mean no scrutiny. The government still negotiates price, checks responsibility, verifies SDVOSB status, and reviews the justification. It does not mean the award is permanent either: sole-source contracts have defined periods of performance, and follow-on work is usually competed or re-justified. And it does not excuse poor performance: a sole-source award that goes badly makes the next justification much harder to write. Treat every sole-source contract as an audition for the next one.
How to Position Your Firm for Sole-Source Awards
Start by identifying agencies and program offices that buy what you sell repeatedly. Study their past awards on USAspending.gov and FPDS to see which requirements were awarded sole-source and at what values. Attend industry days, respond to sources-sought notices, and request meetings with small business liaison officers. In those meetings, be specific: name the problem you solve, the agencies you have served, and the outcomes you delivered. Generic claims like “we do IT services” do not support a sole-source justification; a statement like “we maintained this VA facility’s HVAC controls for three years with zero failed inspections” does.
Also keep your house in order. An expired SAM.gov registration, a lapsed VetCert verification, or an incomplete capability statement can kill a sole-source award at the last step. Contracting officers will not wait while you fix paperwork, they will move to the next option. Review our SDVOSB certification guide and our verification documents checklist to make sure nothing is out of date.
Sole-Source vs Set-Aside: Which Should You Pursue?
Set-asides compete a requirement among SDVOSBs, while sole-source awards skip competition entirely. Set-asides are more common and available at higher values, so most firms will win more set-aside work over time. Sole-source awards are rarer but faster and less costly to pursue. A smart strategy pursues both: compete aggressively in SDVOSB set-asides in your core NAICS codes, and cultivate two or three program-office relationships where a sole-source justification is realistic. Over time, the set-aside wins build the past performance that makes future sole-source justifications credible.
Common Mistakes to Avoid
Do not ask a contracting officer to “just sole-source it to us” without a defensible reason; that request damages credibility. Do not assume the threshold you read last year is still current; thresholds change, so verify before you quote them. Do not let verification lapse mid-pursuit. And do not price a sole-source proposal as if there is no check: the government compares your price to market rates and independent estimates, and an unreasonable price can stop the award cold. Price fairly, document your basis, and be ready to negotiate.
Using GovQon to Find Sole-Source Opportunities
GovQon helps you track SDVOSB set-asides and sole-source notices, monitor agencies that buy in your NAICS codes, and organize the past performance and capability evidence that supports a sole-source case. Pair that with disciplined outreach to program offices, and sole-source awards can become a steady, low-cost channel alongside your competitive pipeline. The limits exist to keep the system fair, but within them, a prepared SDVOSB has a real advantage. Stay verified, stay visible, and make the justification easy, and contracting officers will remember your firm when the next direct award is on the table.

SDVOSB Sole-Source Limits: Know the Ceiling Before You Ask
Before you ask a contracting officer for a sole-source award, know the SDVOSB sole-source limits that apply to your requirement. The SDVOSB sole-source limits are set by statute, not by the agency, and they decide whether a direct award is even possible. If your requirement is above the SDVOSB sole-source limits, the agency must compete it — no matter how good your firm is.
Keep your VetCert verification current, because SDVOSB sole-source limits only help firms that are verified at the time of award. If the VA is your target, read our VA Vets First guide to see the higher VA thresholds, and check the SBA’s official SDVOSB sole-source limits and verification rules. Treat the SDVOSB sole-source limits as a planning tool: price and package your work to fit under them, and the sole-source path stays open.
