Quick Answer

Sole source contracting allows agencies to award contracts without competition when only one source can meet the government's needs. This includes unique capabilities, urgent requirements, or statutory authority for small business set-asides. Small businesses can receive sole source awards up to $4.5 million ($9 million for manufacturing) through 8(a), HUBZone, SDVOSB, and WOSB programs.

What is Sole Source Contracting?

Sole source contracting is a procurement method where an agency awards a contract to a specific contractor without conducting a full and open competition. While competition is the preferred method for federal acquisitions, certain circumstances allow agencies to bypass competition and award directly to a single source.

Sole source awards require documented justification and approval at various levels depending on the contract value. These awards represent a significant portion of federal spending and offer unique opportunities for contractors who can position themselves appropriately.

Common Sole Source Scenarios

  • Only one contractor possesses the required proprietary technology
  • Urgent requirements where competition would cause unacceptable delay
  • Authorized small business set-aside programs (8(a), HUBZone, etc.)
  • Continuation of critical services during contract transitions
  • National security or public interest determinations

Legal Authorities for Sole Source

FAR 6.302 establishes seven circumstances permitting other than full and open competition.

6.302-1: Only One Responsible Source

The most common authority. Used when only one source can satisfy agency needs due to:

  • • Unique or proprietary supplies/services
  • • Follow-on contracts for highly specialized services
  • • Patent rights or data rights
  • • Substantial duplication costs

6.302-2: Unusual and Compelling Urgency

Applies when delay from competition would:

  • • Result in serious injury to government or its programs
  • • Seriously endanger human life or public safety
  • • Note: Poor planning does not constitute urgency

6.302-3: Industrial Mobilization

Maintains essential engineering, research, or development capability or sustains an industrial base. Used primarily for defense purposes.

6.302-4: International Agreement

Terms of an international agreement or treaty require non-competitive procurement. Common in allied nation defense programs.

6.302-5: Authorized or Required by Statute

Statutory authority including:

  • • 8(a) Program sole source authority
  • • HUBZone sole source authority
  • • SDVOSB/VOSB sole source authority
  • • WOSB/EDWOSB sole source authority

6.302-6: National Security

Disclosure of the agency's needs would compromise national security. Rare and requires high-level authorization.

6.302-7: Public Interest

Determined by agency head that full and open competition is not in the public interest. Requires Congressional notification for awards over $100M.

Justification & Approval Process

Most sole source awards require a written Justification and Approval (J&A) document that must be approved before contract award.

J&A Required Elements

  • Description of supplies/services
  • Statutory authority cited (FAR 6.302-X)
  • Demonstration that only one source can meet need
  • Market research conducted
  • Actions to increase competition in future
  • Fair and reasonable price determination
  • Technical and requirements certifications
  • Competition advocate review (certain thresholds)

Approval Thresholds

Up to $750,000Contracting Officer
$750,000 to $15 millionCompetition Advocate
$15 million to $100 millionHead of Procuring Activity (HPA)
Over $100 millionSenior Procurement Executive

Small Business Sole Source Programs

Positioning for Sole Source Awards

Build Agency Relationships

Engage with program offices, attend industry days, respond to RFIs. Agencies award sole source to contractors they know and trust.

Develop Unique Capabilities

Proprietary technology, specialized expertise, or patents create sole source opportunities under FAR 6.302-1.

Leverage Certifications

8(a), HUBZone, SDVOSB, and WOSB certifications provide statutory sole source authority with dollar thresholds.

Excel on Current Contracts

Outstanding performance on existing work positions you for follow-on sole source awards citing continuity of services.

Help Write the J&A

Provide capability statements and market research that supports the agency's justification for sole source.

Monitor Sources Sought

Agencies use Sources Sought to determine if competition exists. Respond quickly to influence procurement strategy.

Ethical Considerations

While positioning for sole source is legitimate, avoid creating artificial barriers to competition. Agencies must justify sole source awards, and false or misleading information can result in contract termination and debarment.

Risks & Considerations

Risks for Contractors

  • • Intense price scrutiny (no competition to establish market)
  • • Potential for protests from excluded competitors
  • • Higher audit likelihood for cost-type contracts
  • • Reputational risk if award is challenged
  • • Pressure to accept less favorable terms

Risk Mitigation

  • • Maintain thorough cost documentation
  • • Support agency's J&A with factual information
  • • Price fairly—don't exploit sole source position
  • • Document your unique qualifications
  • • Keep excellent performance records

Frequently Asked Questions

Can I request a sole source award?

You can suggest it and provide supporting information, but the decision rests with the agency. Focus on demonstrating your unique qualifications and helping the agency document justification.

Are sole source contracts published on SAM.gov?

Sole source awards over $25,000 must be published. However, the solicitation phase is skipped—you'll only see the award notice. Sources Sought notices may indicate potential sole source opportunities.

Can sole source awards be protested?

Yes, competitors can protest that the justification is inadequate or that competition was improperly excluded. Protests are filed with GAO or the agency. Strong J&A documentation reduces protest risk.

What's the difference between sole source and single bid?

Sole source means no competition was held. Single bid means competition was held but only one offer was received. Single bid awards don't require J&A documentation but may face additional price scrutiny.

How do 8(a) sole source awards work?

Agencies can offer requirements to SBA, which then awards to an 8(a) firm. No J&A is required for awards under the threshold ($4.5M/$9M). SBA must accept the offer and identify a capable 8(a) contractor.
