The official business definition of RFI (Request for Information) and RFP (Request for Proposal) is that they are both tools used by organizations to gather information from potential vendors. RFI is used to obtain general information about a product or service, while RFP is used to obtain specific information from vendors to make an informed decision about a purchase. An RFI is typically used to identify potential vendors, while an RFP is used to select the best vendor for a particular product or service. RFI and RFP can both be used to solicit information from vendors, but the process and requirements for each are different. An RFI is typically used to collect information about a product or service, while an RFP is used to solicit detailed proposals from vendors. RFI and RFP are both important tools for organizations to use when selecting vendors and making purchasing decisions.
