Phase III SBIR refers to the commercialization phase where companies that successfully completed Phase I and Phase II SBIR projects win government acquisition contracts for their developed technology. Unlike Phase I and II, which provide R&D funding, Phase III consists of non-SBIR-funded government contracts where the company sells the proven solution to federal agencies. Phase III is the pathway from R&D funding to real contract revenue. SBIR Program rules require agencies that funded a Phase II project to give preference to that company for Phase III procurement.
Opening Definition
Phase III SBIR represents federal acquisition contracts for companies commercializing technology developed through Phase I and Phase II SBIR R&D funding. Phase III contracts are non-SBIR-funded procurement contracts where companies sell solutions to government agencies.
Why It Matters for Tech Companies
Phase III SBIR is the ultimate goal of the SBIR program—converting R&D funding into real contract revenue. Companies that win Phase I ($50K-$150K) and Phase II ($200K-$750K) SBIR funding develop innovative solutions. Phase III is where you commercialize and scale. The agency that funded your Phase II must give your company preference for Phase III procurement if your solution meets their needs. This preference significantly improves win rates. For tech startups, Phase III provides a credible pathway from government-funded innovation to sustainable federal contracting revenue. Phase III contracts often range $100K-$10M+ depending on agency needs and solution scope.
How It Works in Practice
Phase I: Proof of Concept (6 months, $50K-$275K) You propose innovative technology. If selected, you receive Phase I funding to prove technical feasibility. Phase II: Development (2 years, $200K-$1.5M) You develop working prototype or MVP. During Phase II, identify Phase III commercialization pathway and build relationships with agencies. Phase III: Commercialization (Varies, $100K-$10M+) The agency that funded Phase II needs to acquire your solution at scale. They issue Phase III procurement contract. You win through: agency preference (since you developed solution they funded), competitive bidding, or other acquisition vehicles. Example: Autonomous supply chain monitoring startup wins Phase I SBIR with DoD ($100K). Develops proof of concept. Wins Phase II SBIR with DoD ($500K). Develops working system. At Phase II completion, DoD procurement office issues Phase III contract for system implementation: $5M over 3 years. Total: $5.9M funded partly by SBIR grants ($900K), partly by Phase III contracts ($5M).
Common Mistakes to Avoid
- Not thinking about Phase III during Phase II: Plan Phase III from Phase I proposal.
- Only targeting the agency that funded you: Your Phase II agency gives preference but may not have budget. Identify other agencies that could use your solution.
- Developing technology without business model: Validate government demand for Phase III.
- Overestimating Phase III preference: Preference helps; it doesn't guarantee awards.
- Neglecting commercial path: Phase III doesn't mean government contracts only.

Frequently Asked Questions
Is Phase III funding guaranteed after Phase II?
No. Phase III is not funding—it's acquisition. You win Phase III contracts through competitive bidding or agency preference.
Can I do Phase III without Phase I and II?
Yes. Phase III is open to any company. However, Phase I/II participation accelerates development and gives agency relationships.
How long after Phase II does Phase III happen?
Highly variable. Some Phase III begins during Phase II. Others take 1-3 years post-Phase II.
Can I use other acquisition vehicles for Phase III?
Yes. You can commercialize through GSA Schedule, IDIQ, OTA, or other vehicles.
