RFIs and RFPs are distinct work
Why treating an RFI like an early draft of an RFP response loses the relationship. RFIs are informational for the buyer, not a preview of evaluation. Respond to them as such.
A Request for Information is not an early draft of a Request for Proposal. The two documents look similar on the page — both arrive as PDFs from procurement, both list questions, both have deadlines — and smaller teams treat them as a single workflow. That is a mistake. The work is different, the reader is different, the winning response is different.
What the RFI actually is
An RFI is a buyer admitting they do not yet know what they are buying. Procurement is gathering information to write a better RFP later, or to decide whether to bid-out this category at all. The reader on the buyer side is usually a category manager or a strategy analyst, not an evaluation panel. They are trying to figure out what exists in the market, what it costs roughly, and what the trade-offs are between vendor classes.
An RFP is the buyer telling you they know what they want and are evaluating you against a scoring rubric. The reader is a panel with a weighted matrix. The matrix is the point.
The writing job is not the same.
Three ways teams get the RFI wrong
They pitch. An RFI response that reads like proposal copy — win themes, differentiator statements, “our unique approach” — lands wrong. The reader is not yet in evaluation mode. They are taking notes. A response that over-sells signals that the vendor will be a harder buying conversation later, which is an argument for excluding the vendor from the RFP shortlist rather than including them.
They hide. The opposite failure. The team answers minimally, guards pricing, deflects questions. The buyer reads the answers as noncommittal and moves on. An RFI is an opportunity to educate the buyer about the category — including where your approach is not the right fit. Vendors who tell the buyer “for that use case, you probably want X class of tool, here is what to ask for” earn trust that lands in the RFP they shape.
They spend full-proposal effort on it. A 90-hour proposal response to a 40-question RFI is overcapitalization. The return on that effort is not proportional. An RFI deserves a day or two of senior attention, not two weeks of writer time.
What good looks like
A short, specific, educational response. Clear pricing ranges rather than exact quotes. An explicit note on where your class of tool fits and where it does not. A named contact for the follow-up conversation. A commitment to the deadline the buyer set — VisibleThread has written that understanding the requirements is the biggest factor in proposal outcomes, and the equivalent for an RFI is understanding what the buyer is actually asking for, which is help, not a pitch.
The RFI response is the first draft the buyer has of their own RFP. Your job is to make it a better RFP. If the RFP they write looks like your category’s actual strengths, you have pre-positioned yourself; as Fairmarkit has noted, buyers often draft RFPs as wish lists, and the RFI is the moment where the wish list still has room to be shaped.
Treat the RFI as distinct work. Staff it lighter. Teach, don’t sell. Win the relationship before the evaluation begins.
