RFP and RFx definitions: A procurement glossary from A-Z

So, what is an RFx? Great question. An RFx is a catch-all term that refers to any document that is a ‘request for’ something. It represents documents like requests for proposals (RFPs), request for quotations (RFQs) and more. All of these RFP definitions ⁠— and lots of others ⁠— are commonly used in the procurement process.

Every industry has a language of its own and the RFP and procurement world is no different. Procurement professionals, and the people who interact with them, use a vocabulary full of RFP abbreviations, acronyms, synonyms and specialized terminology. The industry-specific terms can be difficult to navigate, no matter how many RFxs you’ve issued or responded to. 

As our business grows, I regularly need to offer a rundown of RFx definitions and procurement jargon for new hires. To help out, I created this RFx glossary to explain RFP common terms for easy reference. Explore each definition and all of the related terms to become an expert in all things RFP, RFx and beyond.

RFx definition we missed?

The terminology and definitions used in procurement are always changing, evolving and expanding as time goes on. I’m sure that in a year or so, our RFx definitions will almost certainly need to be expanded to include other common request documents. We will strive to continuously update this glossary to offer quick, easy answers to common questions like, “What is RFx?” and “What is an RFI?”

I know I haven’t covered every relevant and related term in this RFP glossary. If I’ve missed a key term or omitted some nuance in these RFP definitions, please reach out and let me know. We’d all be thrilled to hear from you on Twitter or LinkedIn.
