If you work with RFPs and proposals, chances are you’ve run into the term ‘RFx’. But, what is an RFx exactly? Great question. An RFx is a catch-all term that refers to any document that is a ‘request for’ something. Indeed, the ‘x’ stands for various kinds of requests. For example, an RFP is a request for proposal. RFQ may stand for request for quotation. Alternatively, it may stand for request for qualification. In addition, an RFI is a request for information. All of these RFx definitions ⁠— and lots of others ⁠— are commonly used in the RFP and proposal process.

Every industry has a language of its own, and the RFP and procurement world is no different. Naturally, procurement and proposal professionals, and the people who interact with them, use a vocabulary full of RFP abbreviations, acronyms, synonyms and jargon. Whether you’re new to RFPs or a seasoned veteran, you may find it difficult to decipher and navigate these industry-specific terms.

In this blog, which you can download as a PDF for quick reference, you’ll find a rundown of RFx definitions and procurement terminology. Explore each definition and all of the related terms to become an expert in all things RFP, RFx and beyond.
