RFP vs RFQ for IT Services: Which One Do You Need?

The short answer: an RFQ (request for quote) asks "what will this cost?" and an RFP (request for proposal) asks "how would you solve this, and what will that cost?" Use an RFQ when you already know exactly what you are buying and just need comparable prices. Use an RFP when the solution itself is part of what you are evaluating. Most managed IT selections are RFP territory; most hardware purchases and well-specified projects are RFQ territory.

That answer covers maybe 80 percent of cases. The rest of this post handles the other 20: precise definitions, a side-by-side comparison, where the lesser-known RFI fits, and the two expensive mistakes businesses make by choosing the wrong instrument.

Plain definitions

Request for Quote (RFQ)

An RFQ specifies the deliverable completely and asks vendors for a price on it. "Forty laptops with these specifications, imaged and delivered." "Cabling for a 6,000-square-foot office to this drawing, 48 drops." "Microsoft 365 Business Premium licensing for 65 users with migration from this named environment." The defining feature is that you have already made the design decisions. Vendors compete almost entirely on price, availability, and terms, and their responses are directly comparable numbers.

Request for Proposal (RFP)

An RFP describes your situation and goals, then asks providers to propose how they would meet them, with what team, on what terms, at what price. You are buying judgment as much as delivery. Responses differ not just in price but in approach, and evaluating them means scoring capability, fit, references, and contract terms alongside cost. Our step-by-step IT RFP guide covers the full structure.

The third instrument: RFI

A request for information (RFI) is a pre-step, not a selection tool. It asks vendors open questions ("what approaches exist for X, and what do you offer?") to educate you before you commit to a scope. Use one when you genuinely do not know what the market offers, then follow with an RFP or RFQ. Do not use an RFI to shortlist; vendors know an RFI rarely leads anywhere quickly and respond accordingly.

Side by side

A simple test: can you write the spec?

Try to write, in one sitting, a specification so complete that a competent vendor could deliver against it without asking you a single design question. If you can, an RFQ fits: send the spec, collect prices, check the vendors' credentials, pick. If you keep writing sentences like "the vendor should recommend an appropriate approach to backups," you have discovered that you are actually evaluating judgment, and you need an RFP.

A second test is duration. One-time purchases with a clear endpoint lean RFQ. Ongoing relationships lean RFP, because in a multi-year service contract the provider's process, people, and honesty matter more than a snapshot price. Nobody should choose the company holding their backups and admin passwords on price alone.

Worked examples for Maryland SMBs

• A 45-person accounting firm replacing its MSP. RFP. The firm is buying an ongoing relationship, security judgment, and busy-season responsiveness, not a commodity. Price matters, but as one weighted criterion among several.
• A distributor refreshing 60 workstations. RFQ. The spec is writable in an afternoon. Collect three quotes, verify warranty and delivery terms, choose.
• A nonprofit moving offices and needing the new space cabled and networked. RFQ if a floor plan and drop count exist; RFP-lite if they also want someone to design the network. Often the fix is to pay for a small design engagement first, then RFQ the build. Treating the move as a defined project with an owner (see IT project management) keeps this clean.
• A medical practice that must meet HIPAA obligations and does not know its gaps. RFI or an assessment first, then an RFP. Asking for quotes on an undefined compliance scope produces numbers that mean nothing.
• A growing company unsure whether to hire internal IT, outsource, or split the difference. Neither instrument yet. That is a structural question that should be settled before any document goes out; it is exactly what a composition strategy engagement decides. Send an RFP for the outsourced portion once the split is chosen.

The two expensive mismatches

Running an RFQ when you needed an RFP

This is the dangerous one. Asking "what do you charge per user per month?" across five MSPs produces a tidy spreadsheet of incomparable numbers, because each provider quietly assumed a different scope, stack, and service level. The lowest number wins, the excluded scope surfaces over the first year as hourly billing and change orders, and the "cheap" provider ends up costing more than the runner-up while delivering less. If you are comparing managed IT on a single number, you are not comparing anything.

Running an RFP when an RFQ would do

The milder mistake: forcing vendors through a 12-page proposal process for a commodity purchase. It wastes your evaluation time, and good vendors may decline to bid at all, leaving you with the ones desperate enough to over-invest in a laptop order. Match the ceremony to the stakes.

Can you combine them?

Yes, and mature buyers often do. Two patterns work well. First, sequence them: an RFP selects your managed services provider, and later, specific projects under that relationship (a server replacement, a phone system) go out as RFQs, sometimes competitively even if your MSP also bids. Second, embed one in the other: an RFP can contain an RFQ-style pricing appendix with a rigid format, which is exactly what a good RFP's pricing section is. You get judgment evaluated like an RFP and prices comparable like an RFQ.

Getting it done

If you now know which instrument you need, the doing is straightforward: the RFP guide walks through structure and scoring, and an RFQ needs little more than a rigorous spec and a consistent price format. We also run both as free services for Maryland businesses: a structured RFP process or a tight RFQ, with vetted providers invited and the responses scored for you. And when the real question is bigger than the document, choosing the provider itself, that is the core of our MSP broker service.
