RFI, explore the market
A Request for Information is used early, before requirements are firm. The buyer is learning: what solutions exist, which vendors are capable, and roughly what things cost. An RFI is not a competition to win work, it shapes the eventual RFP.
RFP, solicit full solutions
A Request for Proposal asks vendors to propose how they would solve a defined problem, their approach, qualifications, team, and price. It evaluates the whole package, not just cost, and is the format most associated with competitive bidding. See what an RFP is for more.
RFQ, compare prices
A Request for Quotation is used when the buyer already knows exactly what they want and mainly needs a price. The scope is fixed, so vendors compete largely on cost and terms.
Which should you expect?
A simple way to remember it: RFI explores, RFP solicits solutions, RFQ compares prices. Many large purchases move through all three over time.
Frequently asked questions
When should you use an RFI instead of an RFP?
Use an RFI early, when you are still exploring the market and want to learn what vendors can do before defining requirements. Use an RFP once you know what you need and want full proposals.
Is an RFQ the same as an RFP?
No. An RFQ focuses almost entirely on price for a well-defined item, while an RFP evaluates the whole solution, approach, and qualifications, not just cost.
