How to Respond to a Sources Sought Notice
A sources sought notice is market research, not a solicitation — but responding well is one of the highest-leverage capture moves available. This guide shows how to write a response that shapes the deal.
A sources sought notice (a type of Request for Information, or RFI) is how an agency conducts market research before issuing a solicitation. It asks whether capable firms — especially small businesses — exist for an upcoming requirement. Responding is voluntary and does not commit you to bid, but it is one of the most effective ways to influence the eventual solicitation.
Why responding matters
- It signals capability, which helps the agency justify a set-aside that limits competition to firms like yours.
- It lets you shape the requirement — your input on scope, NAICS, and evaluation can be reflected in the final RFP.
- It puts your name and capabilities in front of the program office before competitors engage.
- It tells you a deal is coming early enough to start real capture.
The 'rule of two' and set-asides
Under the 'rule of two,' a contracting officer must set an acquisition aside for small business when there is a reasonable expectation that at least two capable small businesses will submit fair-market offers. Strong sources sought responses from qualified small firms give the agency the evidence it needs to make that determination — which is why responding can directly change who you compete against.
What to include in your response
- Your business name, UEI, CAGE code, and applicable socioeconomic certifications (WOSB, SDVOSB, 8(a), HUBZone).
- The NAICS code(s) you hold and your small-business size status under them.
- Concise, relevant past performance: similar scope, size, and customer, with measurable outcomes.
- A clear statement that you can perform the requirement as described, addressing each capability the notice asks about.
- Any contract vehicles you hold (GSA Schedule, GWAC, agency IDIQ) that the agency could use.
How to write it to shape the deal
Answer the specific questions in the notice, in order. Where the draft scope is broad or ambiguous, offer constructive input — for example, suggesting a NAICS that better fits the work or flagging requirements that unnecessarily limit small-business participation. Stay factual and helpful; this is your chance to be seen as a knowledgeable partner, not just a vendor.
After you respond
Treat the response as the start of capture, not the end. Note the point of contact, track the opportunity to solicitation, and use the lead time to research the incumbent, build your team, and prepare proposal content. Many winners can trace the deal back to a sources sought response months earlier.
Frequently asked questions
Is a sources sought notice the same as an RFP?
No. A sources sought notice is market research and you cannot win an award from it. An RFP (Request for Proposal) is the actual solicitation you bid on. Sources sought notices typically precede the RFP.
Do I have to respond to a sources sought notice to bid later?
Usually not — responding is voluntary and you can generally still bid on the eventual solicitation without having responded. But responding is a strong capture move that can influence the set-aside decision and the scope, so skipping it is a missed opportunity.
How long should a sources sought response be?
Short and targeted — typically a few pages. Answer exactly what the notice asks, lead with relevant past performance, and respect any page limit. Brevity and precision beat a long generic capabilities statement.
