UKWhat is the difference between an RFP, RFQ, and IFB?
An RFQ asks for quotes (simpler buys, price-led). An RFP asks for proposals the agency evaluates and can negotiate (complex, best-value buys). An IFB is sealed bidding — lowest responsive bid wins, no negotiation. The type tells you how much proposal effort the buy deserves.
RFQs dominate simplified acquisitions and Schedule/vehicle orders: fast turnaround, often price-driven, quote exactly what is asked. RFPs run the big negotiated procurements with technical volumes, evaluation factors, and possible discussions. IFBs (sealed bids) appear mostly in construction — public bid opening, low compliant bid takes it.
Match your effort to the format: an RFQ rarely justifies a forty-page response, and an RFP almost never rewards a price-only mindset.
