The RFP Process is a request for a proposal. It is a preferred way for many businesses to decide which supplier they will use. The process itself consists of the client company submitting to a group of preferred suppliers a RFI (request for information), which is a lengthy document asking the supplier to tell its prospective client company about itself. This is a very lengthy set of questions. Then the prospective client will issue the RFP to a reduced prospective set of suppliers. This again is a very lengthy process for clients.
