Is a Phase III SBIR Contract Competed? (No — Here's Why It's Sole Source.)

The single most common misconception about Phase III SBIR is that, at some point in the process, the work has to be competed. It does not. Phase III is a sole-source pathway by design, and the legal authority for that sole source is built into the SBIR statute itself. Understanding why — and being able to explain it clearly to a contracting officer who has not awarded a Phase III before — is one of the highest-leverage skills a Phase II awardee can develop.

Where the sole-source authority comes from.

Phase III sole-source authority is established in three layered places:

• The SBIR statute (15 U.S.C. § 638). Subsection (r) explicitly authorizes federal agencies to issue Phase III awards on a sole-source basis to the SBIR/STTR awardee that performed the prior Phase I or Phase II work, where the proposed work derives from, extends, or completes that earlier effort.
• The SBIR/STTR Policy Directive. The SBA's policy directive operationalizes the statute and requires every participating agency to make Phase III awards available without competition.
• Agency FAR supplements. DoD (DFARS), NASA (NFS), and other agencies have implementation language that recognizes the Phase III authority and tells contracting officers how to use it.

Together, this is a deliberately strong stack. Congress wrote it that way because the SBIR program is built on the premise that small businesses will not invest in the high-risk Phase I/II R&D unless they have a credible pathway to commercialize the result. Competing a Phase III would re-introduce the risk that someone else captures the resulting market — which would gut the program's central bargain.

Why this confuses contracting officers.

The default mental model for any federal contracting officer is: competition is the rule, sole source is the exception. The standard sole-source process under FAR Part 6 requires a written Justification & Approval, an independent review at a higher level, and a fairly tight set of statutory exceptions. Phase III is a different sole-source authority that lives outside that framework.

That is unfamiliar. Many contracting officers will instinctively reach for the FAR Part 6 framework, attempt to build a J&A, and end up with a document that does not quite work. The cleaner approach is to invoke the Phase III authority directly, point to the SBIR statute as the predicate, and use the agency's standard award format with a Determination & Findings (D&F) memorializing the basis. Most agencies' own training materials describe this.

What "not competed" actually means in practice.

"Not competed" means three concrete things that are different from a competitive procurement:

• No pre-award solicitation. The agency does not publish a competitive opportunity on SAM.gov, does not collect multiple proposals, and does not run a source-selection.
• No price competition. Price reasonableness is established through cost or price analysis and market research — not through competing bids.
• No requirement to consider alternatives. The contracting officer is not required to evaluate whether another vendor could perform the work; the statute settles that question in your favor.

It does not mean the award is unscrutinized. The contracting officer is still responsible for documenting price reasonableness, confirming that the proposed work properly derives from, extends, or completes the prior SBIR effort, and meeting standard contract-file requirements (responsibility determination, representations and certifications, and so on). The scrutiny shifts from competitive evaluation to nexus-and-price documentation.

The practical implication for awardees.

Because Phase III is not competed, the path to a Phase III contract looks nothing like the path to most federal awards. You are not responding to a solicitation. You are not optimizing a proposal for an evaluation panel. You are building a customer relationship and a contract file. The "win" is convincing the customer the technology fits their mission and giving the contracting officer the documentation they need to issue the award cleanly.

That is a different muscle than most proposal teams have built. The companies that close Phase III awards consistently are usually the ones that treat the process as customer-and-contract development, not capture management.
