The first time you see an RFQ, an RFP, and an RFI sitting in your pipeline at the same time, it’s easy to treat them like they’re basically the same document with a different cover page. They’re not. Each one signals where an agency actually is in its buying process, and responding to all three the same way is one of the fastest ways to waste a proposal team’s time. Here’s how to tell them apart and what to do with each one.
TLDR:
- RFQs cover buys at or below $350,000 and compete on price; RFPs run FAR Part 15 and compete on approach, past performance, and cost.
- An RFI is market research, not a solicitation. No award comes from it, but a sharp response can shape how the requirement gets written.
- Your RFQ response is not a legal offer. The government makes the offer by issuing a purchase order, which you accept by beginning performance.
- Skipping RFIs and over-writing RFQ responses are the two mistakes that cost contractors the most before a solicitation even drops.
- Sweetspot monitors SAM.gov, FPDS, USAspending, and 1,000+ state and local sources, and auto-builds a compliance matrix from Section L and M when a solicitation posts.
What Is an RFQ (Request for Quotation)?
A request for quotation (RFQ) is a solicitation an agency issues to ask vendors for pricing on specific, well-defined goods or services it already intends to buy. Agencies use RFQs for lower-dollar, commercial purchases where the requirement is clear and price is the main variable.
Here is the distinction that trips people up: under federal procurement rules, a quotation is not a binding offer. When you respond, the government makes the offer by issuing a purchase order, and you accept it. That differs from a sealed bid, which locks in your price, and from an RFP, where you compete on approach and value beyond price alone.
What Is an RFP (Request for Proposal)?
A request for proposal (RFP) is the solicitation an agency issues when it needs more than a price. RFP stands for request for proposal, and agencies use it for complex, higher-dollar work where how you plan to do the job matters as much as what you charge.
RFPs run under FAR Part 15, Contracting by Negotiation. Your response is a legal offer the government can accept as written, so every commitment counts.
Evaluation weighs several factors, not price alone:
- Technical approach
- Past performance
- Management approach
- Cost or price
How agencies trade those factors against each other is where RFPs part ways with RFQs and RFIs, covered next.
What Is an RFI (Request for Information)?
A request for information (RFI) is a market research tool, not a solicitation. Agencies issue RFIs to gather intel before deciding what to buy or how to buy it. Responding produces no contract award, and under FAR 15.201(e), an RFI cannot be used to obtain a promise of future business.
Agencies use RFIs to scope requirements, gauge small business participation, and pick between contract vehicles. Research-focused agencies may also issue a Broad Agency Announcement for basic or applied research instead of a traditional RFP. Nothing obligates the government to issue a later solicitation.
Still, respond strategically. A sharp RFI answer can shape how requirements get written, put your name in front of the contracting officer early, and flag set-aside interest before an RFP posts.
RFP vs RFQ vs RFI: Key Differences
Everything above resolves into a single side-by-side view. The table below lines up the three document types across the distinctions that matter when you decide how to respond.
| Dimension | RFQ | RFP | RFI |
|---|---|---|---|
| Purpose | Get pricing on a defined buy | Compete on approach and value | Market research |
| FAR authority | FAR Part 13 | FAR Part 15 | FAR 15.201 |
| Response a legal offer? | No | Yes | No |
| Typical dollar range | At or below $350,000 | Above $350,000 | None |
| Response complexity | Low | High | Moderate |
| Evaluation method | Price and basic terms | Multi-factor tradeoff | Not scored |
The dollar line is the fastest tell. As of October 1, 2025, the Simplified Acquisition Threshold sits at $350,000, so agencies lean on RFQs at or below that level and reserve RFPs for larger negotiated work.
When Federal Agencies Use Each Document Type
Each document maps to a stage in the buying cycle. Early on, when an agency is still scoping a need, it issues an RFI to survey the market. Once the requirement firms up, it moves to either an RFQ or an RFP depending on complexity and dollar value.
The common sequence runs RFI first, then a formal solicitation. Plenty of agencies skip the RFI when they already know the market, and an RFQ sometimes appears as a quick pricing check before a larger competition.
Three scenarios show how this plays out:
- IT hardware buy off a GSA Schedule: RFQ. The item is defined, the vehicle is set, and price is the variable.
- DoD cybersecurity services contracts: RFP. Technical approach and past performance carry the award.
- Pre-solicitation survey for a new logistics program: RFI. The agency is still shaping requirements and gauging small business interest.
How the RFQ Process Works in Federal Contracting
A federal RFQ moves through a predictable sequence:
- Posting. Agencies list RFQs on SAM.gov for open-market buys, or on GSA eBuy when the requirement runs against GSA Schedule holders.
- Distribution. Vendors receive the requirement, quantities, delivery terms, and a response deadline.
- Return. You submit pricing plus any basic qualification the notice asks for. Full technical narratives are rare here.
- Evaluation. The contracting officer reviews on price and whether you meet the stated terms, not a scored proposal.
- Award. The government issues a purchase order or task order.
That purchase order is the actual offer. You accept it by beginning performance, which is why a quotation stays non-binding until then.
GSA eBuy narrows the field. Only Schedule holders see those RFQs, so you compete in a smaller, pre-qualified pool, a real edge for small businesses holding a schedule contract, especially those in the 8(a) Business Development Program.
What to Include in an RFQ Response
An RFQ response stays lean. The agency already knows what it wants, so your job is to price it cleanly and confirm you can deliver on the stated terms. Skip the long technical narrative you would build for an RFP.
Before you submit, confirm each of these:
- Price per unit and per line item, organized by CLIN (Contract Line Item Number)
- Delivery terms, lead time, and any FOB or shipping details
- Vendor qualifications or past performance references, only where the notice asks
- Certifications and representations required by the solicitation
- Page limits and formatting instructions followed exactly
Treat page limits and formatting as binding. Contracting officers can reject a quote that runs long or ignores the notice’s structure, and on a price-driven buy, there is no room to argue technical merit after the fact.
Real Examples of RFQs, RFPs, and RFIs in Government Contracting
RFQ: Air Force base ordering office supplies
An Air Force installation posts an RFQ on GSA eBuy for a set quantity of printer toner against an existing GSA Schedule. The defined quantity and vehicle signal a late-stage buy where price is the only open question. Your response: unit pricing by CLIN, delivery lead time, schedule confirmation.
RFP: Civilian agency buying managed IT services
A civilian agency issues an RFP under NAICS 541512 for a multi-year managed IT contract, requiring technical, past performance, and price volumes. Vendors may also need to satisfy Authority to Operate requirements for any delivered systems. A firm requirement headed to negotiated award. Your response: a full proposal mapping every Section L instruction, winning on approach and CPARS-backed past performance.
RFI: Defense agency scoping a logistics IDIQ
A defense agency posts an RFI on SAM.gov to gauge small business capability before drafting a logistics IDIQ. Civilian-side buyers such as State Department contractors follow a similar RFI-to-RFP sequence. Early-stage market research, no award attached. Your response: a capability statement, set-aside status, and input that shapes the coming requirement.
Common Mistakes Contractors Make with RFQs, RFPs, and RFIs
Most of these errors come from misreading what a document actually asks for. A few show up again and again:
- Skipping RFIs from target agencies. An RFI produces no award, so teams ignore it and lose the chance to shape requirements before the RFP drops. Respond with a tight capability statement even when nothing is guaranteed.
- Treating an RFI as a live contract. It is market research, so give the agency the intel it asked for instead of pitching pricing or promising delivery.
- Answering an RFQ with an RFP-style narrative. Keep it to price, terms, and only the qualifications requested.
- Ignoring Section L formatting. Font, margins, and technical proposal page limits are pass or fail. Build against it line by line before drafting.
- Reading the SOW and skipping Section M. Evaluation criteria live there. Shred both L and M into your compliance matrix.
- Lowballing an RFQ. An unsustainable margin costs you on performance and the recompete. Price to deliver.
