An RFQ (Request for Quotation) asks for your price on a requirement the government has already defined. An RFP (Request for Proposal) asks for a technical approach as well as a price, and the agency judges both against stated evaluation factors. To tell them apart in a federal solicitation, check the FAR provisions it cites and the word it uses for your response. The two also differ legally in what happens after you submit, which the definitions section below covers.

Which option is right for you?

The quickest way to decide is to match your situation to the notice type on SAM.gov and open the document that controls your response.

What Is RFQ and RFP? (The Core Definitions)

Beyond the price-versus-approach difference, the FAR draws a legal line between the two, and it affects you after you hit submit.

FAR 2.101 defines "offer" this way: responses to invitations for bids are "bids," responses to requests for proposals are "proposals," and responses to requests for quotations "are 'quotations,' not offers." FAR 13.004 explains the effect: "A quotation is not an offer and, consequently, cannot be accepted by the Government to form a binding contract." If the government issues an order based on your quote, the order is the government's offer. A contract exists only once you accept it, either in writing or by delivering or substantially performing the work.

Dollar thresholds decide which method an agency can use. As of October 2026, FAR 2.101 sets these values:

FAR 13.003 tells agencies to use simplified acquisition procedures "to the maximum extent practicable" for purchases at or below the SAT, and an RFQ is the standard tool for those purchases. Above that level, and for complex buys, agencies usually switch to FAR Part 15 negotiation and the RFP.

A 2026 wrinkle: the FAR overhaul

Under the Revolutionary FAR Overhaul (RFO), many agencies now follow class deviations that differ from the codified FAR. The RFO Part 12 deviation text tells agencies to issue "a request for quotations (RFQ) followed by a purchase order" for commercial acquisitions up to $9 million ($15 million in certain emergencies). Above $9 million, agencies use Part 15 RFPs or Part 14 invitations for bids, and the deviation says "Use of an RFP is the preferred method because it includes consideration of past performance." The RFO Part 13 deviation narrows Part 13 to noncommercial buys at or below the SAT. Proposed rules covering Parts 12, 13 and 15 (FAR Case 2026-003) had a comment deadline of October 19, 2026, according to the SBA Office of Advocacy. The practical result: a commercial RFQ can now be much larger than $350,000. Go by the clauses each solicitation actually cites, not by older rules of thumb.

What Is RFQ and RFP in Procurement? How the FAR Actually Labels Them

In federal procurement, the clauses cited inside the document tell you the solicitation type more reliably than the title on the cover. Agencies reuse forms and templates, so a "Request for Quote" header can sit on a document that cites Part 15 evaluation language, and the reverse also happens.

Here are five clues, in the order to check them.

1. The statement at the top of a combined notice. FAR 12.603(c)(2) requires "a statement that the solicitation is issued as an invitation to bid (IFB), request for quotation (RFQ) or request for proposal (RFP)." Use the Find command (Ctrl+F) to search for those three acronyms.
2. The noun used for your response. Search for "quotation," "quoter," "proposal" and "offeror." A document that asks for "quotations" from "quoters" is using simplified acquisition. One that asks for "proposals" from "offerors" and mentions a "competitive range" or "discussions" is using Part 15 negotiation.
3. The instructions provision. 52.212-1 (Instructions to Offerors—Commercial Products and Commercial Services) appears in commercial solicitations of every kind. 52.215-1 (Instructions to Offerors—Competitive Acquisition) signals a Part 15 negotiated procurement. If you see 52.212-1 together with an addendum that adds Part 15-style volumes, prepare a proposal.
4. How evaluation is described. For simplified buys, FAR 13.106-1 only requires the agency to state "the basis on which award will be made (price alone or price and other factors, e.g., past performance and quality)." An RFP under FAR 15.203 must list "factors and significant subfactors that will be used to evaluate the proposal and their relative importance." A ranked list of factors with relative weights means RFP.
5. The estimated value and the form. Under FAR 13.307, simplified acquisitions use the SF 1449 or the SF 18 (Request for Quotations). If the estimate is clearly above the threshold that applies (the $350,000 SAT, or $9 million for commercial buys under the RFO deviation) and you can't find simplified-procedure language, assume Part 15.

Example (illustrative): Suppose a notice is titled "RFQ – Janitorial Services," cites 52.212-1, and says award goes to "the lowest-priced technically acceptable quote." That is an RFQ, and your package is a price plus proof that you meet the specs. Now suppose a notice is titled "Janitorial Services," cites 52.215-1, and says "technical approach is significantly more important than price." That is an RFP, even though the work is the same.

What Is RFI vs RFP? Where the Information Request Fits First

An RFI is market research. You submit nothing binding and no award follows. FAR 15.201(e) says RFIs "may be used when the Government does not presently intend to award a contract, but wants to obtain price, delivery, other market information, or capabilities for planning purposes," and adds that responses are not offers.

Pitfalls and fixes

• Sending a 40-page proposal to an RFI. Reviewers are looking for capability and interest, not pricing tables. Fix: answer only the questions asked and lead with a concise capability statement. Our capability statement example shows which sections buyers read first.
• Skipping RFIs because "there's no contract." Agencies use the responses to decide whether enough small businesses can do the work. Fix: if you could realistically perform the work, respond and state your size status under the notice's NAICS code. Our guide to SBA size standards by NAICS explains how to check it.
• Quoting firm prices in an RFI. Fix: give ranges or mark figures as rough order of magnitude (ROM) for planning only.

What Is RFI and RFP Process? The Typical Sequence in Federal Contracting

A typical sequence runs from Sources Sought or RFI, to presolicitation or draft RFP, to final RFP, then proposals, evaluation and award. New bidders often switch into proposal mode while the agency is still at the RFI stage.

FAR 15.201(c) lists the early-exchange tools agencies may use: industry conferences, one-on-one meetings, presolicitation notices, draft RFPs, RFIs, preproposal conferences and site visits. FAR 10.002 separately lists market research techniques, including "interchange meetings or holding presolicitation conferences."

Here is how the timing works under FAR 5.203:

1. Sources Sought / RFI (optional). There's no minimum response time in 5.203, so these can close within days.
2. Presolicitation notice. For most actions it must be published "at least 15 days before issuance of a solicitation." Contracting officers can set shorter periods for commercial buys.
3. Solicitation (RFP or RFQ). For acquisitions above the SAT, the minimum response time is 30 days from issuance. Research and development requires at least 45 days. For commercial buys over $25,000, the contracting officer sets a "reasonable" time.
4. Questions and amendments. Amendments arrive as SF 30 modifications (FAR 13.307 lists the SF 30), and you must acknowledge each one. 52.212-1(b) lists "acknowledgment of solicitation amendments" as a required item.
5. Evaluation and award. The default under 52.215-1(f)(4) is award without discussions, so the government expects your best terms in the first submission.
6. Award Notice (SAM.gov notice type "a").

To follow one opportunity through these stages on SAM.gov:

1. Go to SAM.gov, select Search, and choose the Contract Opportunities domain.
2. In the Notice Type filter, pick Sources Sought and Presolicitation for early work, or Solicitation and Combined Synopsis/Solicitation for live bids.
3. Add your NAICS Code and Set Aside filters.
4. Open a notice and select Follow so that new versions and amendments under the same notice ID are easy to track.
5. Read the Description and every file under Attachments/Links. The FAR clauses are usually in the attachments, not the summary.

Pitfall: treating a Combined Synopsis/Solicitation like a presolicitation. Under FAR 12.603, the notice states "This announcement constitutes the only solicitation." No second document is coming, and the clock is already running.

What Is RFI and RFP in Sales? How Commercial Usage Differs From Federal Rules

In private-sector sales, buyers use RFI, RFQ and RFP loosely, and no regulation like the FAR fixes what each one means. A federal response strategy won't carry over unchanged.

The FAR is the federal baseline. It defines who is making an offer (FAR 2.101), how late submissions are handled (52.212-1 and 52.215-1), and what an RFP must disclose about evaluation (FAR 15.203). A corporate procurement team follows its own policy and its own contract terms.

Example (illustrative): A hospital system's "RFP" might be a two-page spreadsheet of unit prices, which functions as an RFQ. Its "RFI" might include a pricing tab it later holds you to. A company's purchasing department might negotiate with two finalists after a "final" deadline, a step the FAR's late-proposal rules would generally bar in a federal acquisition.

Pitfalls when moving between the two worlds

• Assuming commercial flexibility applies in federal bids. A federal proposal that misses the deadline is usually rejected. 52.212-1 allows only narrow exceptions, such as an electronic submission received by 5:00 p.m. one working day before the deadline, or the only proposal received. Fix: plan your upload to finish a day early.
• Assuming federal protections apply in commercial deals. Without a FAR-style evaluation section, a private buyer may never tell you how price was weighed. Fix: ask in writing how the decision will be made before you invest heavily.
• Reusing a sales deck as a federal technical volume. Fix: rebuild it to match the solicitation's instructions section by section.

What Is RFI, RFQ and RFP? Comparing All Three Side by Side

Seen together, the three differ most in where they sit in the FAR, how large the buy can be, and how much the agency must tell you about evaluation.

Example (illustrative): An agency that needs 200 ruggedized laptops might post an RFI asking which models meet a draft spec. Once the spec is fixed, it could post an RFQ asking for unit price and delivery date. If it later decides it needs a vendor to design, deploy and support a field computing system, that is an RFP, because the agency is now comparing approaches.

What Is the Difference Between RFQ and RFP in What You Must Submit?

Day to day, the difference shows up in the paperwork: an RFQ package is mostly a priced quote plus required representations, while an RFP package is a set of separate volumes laid out exactly as Section L instructs.

Sources: 52.212-1, 52.215-1, 15.204-1.

Steps to build the right package

1. Search the solicitation for "52.212-1" and "52.215-1" and note any "Addendum to 52.212-1." Addenda often add page limits and volumes.
2. In an RFP, copy every "shall" sentence from Section L (or the addendum) into a compliance checklist, one row per sentence. Then copy the factors from Section M next to it so your headings match how evaluators score.
3. Confirm the set-aside type and your size under the NAICS code. If you're unsure how a partial set-aside changes who can win which part, read our total vs partial set-aside checklist.
4. Price exactly the line items listed in Section B or the SF 1449 schedule. Don't merge or rename CLINs.
5. Acknowledge every amendment and submit through the method the solicitation names.

Pitfalls and fixes

• Adding marketing material to an RFQ. If award is on price alone, extra pages don't score. Fix: send the price, the spec confirmations and the required forms.
• Leaving out a past performance volume in an RFP. Fix: when Section M lists past performance, follow the format and number of references Section L asks for. If you have no federal history, include relevant commercial work when the instructions allow it.
• Writing "pricing valid 15 days" when the solicitation asks for 30 or more. Fix: match or exceed the acceptance period in the solicitation.
• Assuming you can fix the proposal later. 52.215-1 states the government intends to award without discussions. Fix: submit your best price and approach the first time.

RFQ vs RFP vs RFI vs RFT vs RFB vs Tender: One Comparison Table

RFT and "tender" are used mainly outside the U.S. and correspond most closely to a U.S. RFP or invitation for bids. RFB overlaps with sealed bidding under FAR Part 14. Map each term back to the closest FAR method before deciding what to send.

The UK's Procurement Act 2023, for example, describes awarding contracts to the supplier with "the most advantageous tender in a competitive tendering procedure" (section 19). In the FAR, the formal term for a bid request is "invitation for bids" (IFB). Under FAR 14.101, bids "shall be evaluated without discussions," are "publicly opened," and award goes to the responsible bidder whose conforming bid is most advantageous "considering only price and the price-related factors."

All FAR citations above refer to the codified FAR text as shown on acquisition.gov when checked in October 2026.

Next steps

You can do the first round of this work yourself today, starting with one real notice.

DIY actions for today

1. If you don't have an active SAM.gov registration yet, start it now. FAR 4.1102 requires it at the time you submit an offer or quotation. Our SAM.gov registration guide walks through the steps.
2. On SAM.gov, filter Contract Opportunities by your NAICS code and Notice Type = Combined Synopsis/Solicitation. Open three notices and run the five clue checks from the section on how the FAR labels RFQs and RFPs. Write down whether each one is an RFQ or an RFP and which provision told you.
3. Find one Sources Sought notice in your NAICS code and respond with a two-page capability statement using our Sources Sought template.

If you'd rather not do it alone

• APEX Accelerators: free. These centers operate under a Department of Defense cooperative agreement and offer counseling at no cost, including bid reviews and registration help (Washington APEX Accelerator; DC APEX Accelerator). Good for first-time bidders who want someone to check their reading of a solicitation. Not ideal if you need someone to write a 50-page proposal for you. Counselors advise rather than ghostwrite, and availability varies by location.
• Independent proposal writers or consultants: paid. There is no official rate card, so ask for a fixed written quote per solicitation (as of October 2026; check each firm's current terms). This can make sense for a firm chasing a large RFP with a short deadline. It's usually a poor fit for RFQs, where the package is mostly your price and can be done in-house. Before you sign, keep in mind that the consultant can't supply past performance you don't have.

FAQ

What is RFQ RFP process timeline for a typical federal solicitation?

For acquisitions above the simplified acquisition threshold, FAR 5.203 generally requires a notice at least 15 days before the solicitation and at least 30 days to respond after it's issued (45 days for R&D). Commercial buys can have shorter, "reasonable" response times set by the contracting officer. RFQs under the SAT often close in days, so check the response date on every notice.

Can an RFQ turn into an RFP if the agency changes its requirement?

An agency can cancel an RFQ and reissue the requirement as an RFP, or amend the solicitation, if the requirement or estimated value changes. For example, the RFO Part 12 deviation moves commercial buys over $9 million to Part 15 or Part 14. Follow the notice on SAM.gov and read each amendment for changes to the cited provisions.

Is a response to an RFQ legally binding like a bid under sealed bidding?

No. Unlike a sealed bid, a quotation is not an offer (FAR 13.004); see the core definitions section above for how a contract forms from an order. Even so, quote only prices you're prepared to honor.

Do I need a SAM.gov registration to respond to either an RFQ or RFP?

Yes, in most cases. FAR 4.1102 says "Offerors and quoters are required to be registered in SAM at the time an offer or quotation is submitted." Exceptions are narrow, such as certain micro-purchases paid by government purchase card and some classified or urgent actions.
