RFP vs RFI
RFI and RFP are the two formal documents enterprise buyers send to vendors. Confusing them is how deals get disqualified before they start.
The key difference: An RFI gathers information to shortlist vendors. An RFP asks shortlisted vendors to actually propose a solution and price.
| Dimension | RFP | RFI |
|---|---|---|
| Purpose | Solicit a formal proposal + price | Gather information to learn the market |
| Stage | Late — vendors are shortlisted | Early — vendors are being scoped |
| Vendor effort | High — full response, often custom pricing | Lower — capability overview |
| Outcome | Vendor selection | Shortlist for the next round |
| Typical companion | SOW, MSA, contract | Vendor briefings, demos |
When to use RFP
Use RFPs when the buyer knows what they want and needs vendors to bid against the same scope.
When to use RFI
Use RFIs when the buyer is still defining the problem and needs market context before committing to a process.
FAQs
Should every RFI lead to an RFP?
No — that's the point of the RFI. It exists so the buyer can scope intelligently and only invite a short list to the RFP.
How long should an RFP response take?
Typical enterprise RFPs run 20–80 hours per vendor, depending on complexity. Most successful vendors use a response library to bring that down.
Is an RFQ the same as an RFP?
No. An RFQ (Request for Quote) asks only for price on a fully-specified product. An RFP asks vendors to propose a solution.
