RFP vs RFQ: When Does the Government Use Each?

What Is a Request for Proposal (RFP)?

A Request for Proposal is a negotiated-procurement solicitation issued under FAR Part 15. The contracting officer asks offerors to propose a full solution: a technical approach, management plan, past performance documentation, key personnel, and a priced offer. The government evaluates proposals using stated criteria (often a best-value tradeoff between technical merit and price) and may conduct discussions, request final proposal revisions, and select an offeror based on the integrated evaluation.

RFPs result in a contract award, typically a single firm-fixed-price, cost-plus, or time-and-materials contract per the requirement. Responding to a federal RFP is substantial work — technical volumes typically run 50-200 pages, and proposal teams spend weeks or months on a single response. Awards usually take 90-180 days from RFP release to contract signature.

What Is a Request for Quote (RFQ)?

A Request for Quote is a simplified-acquisition solicitation issued under FAR Part 13. The contracting officer is buying a commercial or commercial-like item where the requirement is well-defined and the only meaningful differentiator is price (or price plus a few simple factors). The government asks vendors to submit a quote: pricing, brief technical capability statement (if any), and confirmation of compliance with the SOW.

RFQs typically result in a purchase order (SF-1449) rather than a fully-negotiated contract. The vendor's quote is not an offer in the legal sense — the government's purchase order is the offer, which the vendor accepts by performance. RFQ responses are generally short (a few pages of pricing and capability), and award commonly happens within 30-60 days. RFQs are also the standard mechanism for buys against GSA Schedule contracts and other IDIQs.

Which Solicitation Should You Expect?

Expect an RFP when…

• The buy is above $250K and not against a pre-competed vehicle (GSA Schedule, IDIQ)
• The requirement involves design, integration, R&D, or professional services where approach matters
• Past performance and technical capability differentiate vendors meaningfully
• The acquisition strategy says "negotiated procurement" in the source-selection plan
• The solicitation includes Section L (instructions to offerors) and Section M (evaluation factors)

Expect an RFQ when…

• The buy is at or below SAP ($250K), or is a commercial item under FAR 13.5 (up to $7.5M)
• The requirement is well-specified and the market has multiple ready-to-deliver vendors
• The buyer is placing an order against a GSA Schedule, BPA, or IDIQ (FAR 8.405-2)
• The SAM.gov posting type is "Combined Synopsis/Solicitation" for a commercial buy
• The solicitation references SF-1449 as the award document

A common confusion: a solicitation can be issued as a Combined Synopsis/Solicitation (FAR 5.207) and still be functionally either an RFP or an RFQ. Read the solicitation instructions and the FAR Part citation in the notice header. If you see "FAR Part 13" or "FAR 8.405", it's RFQ-like. If you see "FAR Part 15," it's RFP.

A Third Option: IFB (Sealed Bidding)

You may also encounter an Invitation for Bid (IFB) under FAR Part 14. IFBs are used for construction and other well-defined requirements where award goes to the lowest responsive, responsible bidder — no discussions, no evaluation tradeoff. Bids are opened publicly at a specified time. IFBs are less common today than RFPs and RFQs but remain the default for federal construction work.

In short: IFB = lowest bid wins, no negotiation; RFQ = lowest acceptable quote, simple buy; RFP = best value, negotiated.

Pre-Solicitation Signals

Most RFPs are preceded by market research that produces public artifacts. A Sources Sought notice asks who can perform the work and whether small business set-aside is feasible. A Request for Information (RFI) collects technical input on the approach. A Draft RFP shares the planned solicitation for industry comment. Tracking these signals lets you anticipate RFPs 60-180 days before release.

RFQs typically have fewer pre-solicitation signals because the buy is straightforward. Watch the agency's buying patterns: most agencies repeat similar RFQ buys at predictable intervals (annual maintenance, recurring commodity orders, on-call services). Past contract data is the single best predictor of when the next RFQ will land.
