Pre-solicitation guide

Sources Sought vs. RFI vs. Draft RFP

Sources Sought, RFIs, and draft RFPs are related market-research signals, but they serve different purposes. None is the same as a final solicitation.

Sources Sought tests available capability

A Sources Sought notice commonly asks whether capable firms exist and may inform an acquisition strategy or set-aside decision. Respond to the specific capability questions and do not treat the notice as an invitation to bid.

An RFI gathers planning information

A Request for Information can help an agency learn about capabilities, practices, availability, or possible approaches. Under federal acquisition guidance, an RFI may be used when the government lacks enough information for planning; it is not an offer and cannot be accepted to form a binding contract.

A draft RFP exposes anticipated requirements

A draft solicitation may provide more developed requirements and invite feedback before the final version. Terms, scope, dates, evaluation factors, and even the procurement itself can still change.

  • Read the notice type and response instructions
  • Separate facts from anticipated details
  • Answer accurately and concisely
  • Monitor for the final solicitation or cancellation

Official sources

Use the current official notice and attachments as the controlling source for any procurement decision.

Frequently asked questions

Is an RFI a solicitation?

No. It is generally used for planning and market research rather than requesting offers.

Can a draft RFP change?

Yes. It is a draft, and contractors must rely on the final official solicitation and amendments.

Does responding guarantee an advantage?

No. A relevant response may inform planning, but it does not guarantee a solicitation, preference, or award.
