What is a sole source contract?

A sole source contract is awarded to a single contractor without competition. The federal government requires a formal justification for these awards, but several small business programs make sole-source contracting a realistic path for qualified firms.

How Sole Source Awards Work

Federal procurement law generally requires full and open competition. However, the Federal Acquisition Regulation (FAR Part 6.302) authorizes sole-source awards under specific circumstances. When an agency wants to award a contract without competition, it must prepare a Justification and Approval (J&A) document that explains why only one contractor can meet the requirement.

Common FAR justifications for sole-source awards include:

• Only one responsible source — The contractor has unique expertise, proprietary technology, or exclusive rights that make them the only viable provider.
• Unusual and compelling urgency — The government's need is so urgent that competitive procedures would cause unacceptable delays, such as disaster response or critical system failures.
• Industrial mobilization — National defense requirements that necessitate maintaining a specific contractor's capability.
• Authorized by statute — Certain laws, including those governing small business set-aside programs, explicitly authorize noncompetitive awards.

Small Business Sole Source Thresholds

Small business set-aside programs provide some of the most accessible paths to sole-source awards. Under the 8(a) Business Development Program, agencies can award sole-source contracts up to $4.5 million for services and $7 million for manufacturing directly to 8(a) participants. Similar thresholds apply to HUBZone, SDVOSB, and WOSB sole-source awards.

In practice, this means an agency can hand a $4.5M service contract directly to an 8(a) firm without posting a solicitation or evaluating competitors. For small businesses, building relationships with contracting officers who know your work is often how sole-source awards happen.
