The term "RFX" or "RFx" is used generically to refer to the sourcing practice of issuing a request from supplier providers. The "X" can stand for "I" for "Information" or "Q" for "Quote" or "P" for "Proposal" or "Pricing". It is a term most often used in the beginning stage of the sourcing process, before the exact strategy is determined, as well as in solution provider lingo as a means to define their capabilities.
