While they may seem similar, a request for information (RFI) and a request for proposal (RFP) have different definitions and serve different purposes within the procurement process.
According to RFP360, the difference between the RFI and RFP is what information they provide:
An RFI educates – RFI responses explore how a vendor might solve a problem or fill a need – while an RFP compares – RFP responses evaluate the merits of each vendor compared to others.
In other words, a request for information (RFI) is used when the client wants several consultants to provide potential solutions, while a request for proposal (RFP) is used in a bidding process to solicit offers for a project.
