Request for Proposal (RFP) — definition
Buyer-issued document inviting suppliers to propose a technical approach, methodology and price for a problem or objective that is not yet fully specified.
RFPs are typically used for engineered or turnkey scopes where multiple valid technical solutions exist, such as a new production line or process design. Responses are evaluated on technical merit, methodology, experience and price together, rather than price alone.
Why it matters to industrial buyers
Allowing suppliers to propose their own approach can surface design alternatives, risk allocations, or efficiencies the buyer had not anticipated.
Key reference points
Evaluation criteria
RFP responses are commonly scored with weighted criteria covering technical approach, references, schedule and commercial terms.
Typical use case
Frequently used for turnkey projects, process design-build scopes, and special-purpose machinery.
Commonly confused with
Request for Quotation (RFQ)
An RFP invites solution design and judgement; an RFQ assumes the solution is fixed and compares price against a set specification.
How it is used in practice
A beverage manufacturer issues an RFP for a new bottling line, asking suppliers to propose layout, automation level and commissioning approach.
Frequently asked questions
Is an RFP more time-consuming than an RFQ?
Typically yes, because it requires structured technical evaluation in addition to commercial comparison.
Can an RFP be followed by an RFQ?
Yes, a common sequence is to shortlist through an RFP and then request firm quotations on the selected approach.
