SBIR Phase III is where the technology development funded in Phase I and II becomes a production contract — the transition from R&D to real mission value. It's also where most SBIR awardees struggle. Phase III doesn't come with its own SBIR funding from DoD; it's the bridge where companies must navigate program office relationships, sole-source authority, and procurement timelines to convert research into revenue.
This guide covers the mechanics of DoD SBIR Phase III transition for technology companies.
What Phase III Is (and Isn't)
Phase III is defined as the commercialization phase following a successful Phase II. Key characteristics:
- No statutory funding ceiling: Unlike Phase I ($50K–$300K) and Phase II ($750K–$2M), there is no ceiling on Phase III contract value
- Sole-source authority: Federal agencies can award Phase III contracts directly to SBIR awardees without a competitive solicitation — this is the defining commercial advantage
- Not limited to the original agency: Any federal agency can award a Phase III contract to an SBIR company for technology developed under any agency's SBIR funding — the authority is government-wide
- Not automatic: Program offices must affirmatively choose to exercise sole-source authority. Many don't, defaulting to competitive procurement out of habit
The Sole-Source Authority Mechanism
10 U.S.C. § 4902 (formerly 10 U.S.C. § 2302) authorizes sole-source awards to SBIR awardees for follow-on technology development. The FAR includes provisions supporting this at FAR 6.302-5(b)(7) and DFARS 206.302-5(b)(2).
To use sole-source authority:
- The contracting officer writes a Justification and Approval (J&A) citing the SBIR Phase II work
- The J&A must demonstrate that the technology was developed under an SBIR award
- The contract must be for "work developed under the SBIR program, or for the production of a prototype or follow-on production"
Practical implication: You need to help the contracting officer write the J&A. Come prepared with:
- Your Phase I and Phase II contract numbers
- Documentation of the technology connection to the proposed work
- A simple one-page J&A justification narrative the contracting officer can adapt
Building Program Office Relationships During Phase II
Phase III transitions happen because a program office wants them to happen. The technical work must be compelling, but the contracting outcome is a relationship and trust outcome.
During Phase II:
- Brief the PM/APM/Chief Engineer quarterly, not just at TRLs
- Provide clear "so what" for the program — how does this technology solve their operational problem?
- Get the technology into the hands of users in a representative environment before Phase II ends
- Identify who will advocate for the technology in the program office budget process
The SBIR Transition Assistance Program (TAP) at the DoD SBIR/STTR office provides resources and introductions, but the core relationship work is yours to do.
SBIR Data Rights: Your Competitive Moat
SBIR Data Rights (DFARS 252.227-7018) protect your technical data and computer software from government disclosure for a 20-year period. This is the contractual mechanism that prevents the government from taking your IP and awarding a follow-on production contract to a large prime.
Key data rights points:
- SBIR-developed technology clearly marked with SBIR Data Rights legends
- Government can only use the data for the specific program that funded it
- Third-party disclosure requires your written permission
- Rights survive into Phase III contracts — mark all deliverables correctly
Work with an attorney experienced in government contracts IP to ensure proper marking from Phase I forward. Retroactive marking is difficult.
SBIR Transition Funding Bridges
The gap between Phase II completion and a Phase III contract award is often 6–18 months. Bridge strategies:
SBIR Transition Initiatives: Some services have programs specifically for bridging the gap — Army xTechSearch, Air Force AFWERX transition, DARPA transition vehicles. Seek these out.
STTR Phase III: If your work was STTR-funded (with a research institution), similar transition authority applies.
OTA (Other Transaction Authority): OTAs can be used for Phase III-like work and move faster than FAR-based contracts. Many DoD organizations have OTA consortia that include SBIR companies.
Prime contractor teaming: A prime with an existing program contract can subcontract Phase III work to your company — this is faster than a direct government Phase III contract and introduces you to the prime relationship while your direct contract matures.

FAQ
Can any federal agency award a Phase III contract to an SBIR company?
Yes. SBIR Phase III sole-source authority is government-wide — not limited to the agency that funded Phase I/II. If your technology was developed under an Air Force SBIR but a Navy program office wants to use it, they can award a Phase III sole-source contract. This broad authority is one of the most underutilized advantages in the SBIR program.
How long does a DoD SBIR Phase III contract award take?
Timeline varies significantly by service and program office. Straightforward Phase III awards using established sole-source authority can move in 3–6 months. Awards involving significant contract negotiation, legal review of data rights, or new program office relationships can take 12–18 months. Many companies underestimate this timeline — start the Phase III conversation 12+ months before Phase II ends.
What is the maximum value of a SBIR Phase III contract?
There is no statutory ceiling on SBIR Phase III contract value. Awards range from a few hundred thousand for limited follow-on testing to hundreds of millions for full production. The value is limited only by the program's budget and the negotiated scope of work.
How do SBIR Data Rights affect follow-on competition?
SBIR Data Rights prevent the government from disclosing your technical data to competitors for 20 years. However, the government still retains the right to compete production separately after Phase III if they choose — SBIR Data Rights don't permanently lock out competition. The practical protection is that the government cannot give competitors your technical data to help them compete.
What should I include in a SBIR Phase III proposal to increase award probability?
Focus on: (1) clear connection between Phase II deliverables and the Phase III scope, (2) specific operational problem solved for the program, (3) realistic transition plan with TRL milestones, (4) past performance data from Phase II (schedule, technical quality, cost management), and (5) pricing that reflects actual costs — contracting officers are skeptical of both unusually low and unusually high Phase III bids.
