An RFP (Request for Proposal) is a preliminary document used to solicit bids from potential vendors before a contract is awarded, not a document that governs an ongoing project's terms and conditions.

An RFI (Request for Information) is an even earlier preliminary document used to gather general information from vendors, prior to an RFP or SOW, and does not contain project-specific commercial terms.
