Sole Source Contract
A government contract awarded to a single vendor without full and open competition, permitted under specific legal exceptions in the FAR.
A sole source contract is an award made to one vendor without the competitive bidding process the Federal Acquisition Regulation (FAR) normally requires. While competition is the default in federal contracting, FAR 6.302 permits sole source awards under specific statutory conditions.
When Sole Source Awards Are Allowed
The most common justifications are that only one responsible source exists and no other supply or service will satisfy agency requirements; an unusual and compelling urgency would cause serious injury to the government under competitive timelines; an industrial mobilization or national defense interest is at stake; or follow-on work from a competitive award requires the same source for technical or facility continuity.
The 8(a) Sole Source Advantage
The 8(a) Business Development Program lets SBA award sole source contracts to certified participants up to $4.5 million for services and $7 million for manufacturing, with no competition required. This is one of the most significant financial advantages of 8(a) certification and a primary reason small disadvantaged businesses pursue the program.
Justification and Approval Requirements
For sole source awards above

Early agency engagement, documenting unique proprietary capabilities, maintaining strong incumbent performance, and tracking expiring contracts are the primary ways to position for sole source awards. ProposalApp helps contractors monitor pre-solicitation notices and expiring contracts that signal upcoming noncompetitive opportunities.
Frequently asked questions
What is a sole source justification in government contracting?
A Justification and Approval (J&A) is a written document the contracting officer prepares to explain the legal basis for a noncompetitive award. It must be approved by appropriate authority and is publicly posted for awards over $750,000.
Can small businesses receive sole source contracts?
8(a) certified firms can receive sole source awards up to $4.5 million for services and $7 million for manufacturing without competition. SDVOSB and WOSB programs also allow sole source awards under specific thresholds. These represent major opportunities for qualifying small businesses.
How do I become eligible for a sole source government contract?
Sole source status typically comes from incumbency, unique proprietary technology, or a specialized capability no other vendor can provide. Early customer engagement, strong past performance on related work, and clear documentation of your unique approach are the best ways to position for noncompetitive consideration.
