Request for proposal (RFP)
A request for proposal is a comprehensive solicitation document used when the buyer needs suppliers to propose solutions, not just price known requirements. RFPs invite suppliers to describe their approach, methodology, qualifications, and pricing for complex needs where multiple valid solutions exist. This format enables evaluation of both solution quality and cost, appropriate when the "how" matters as much as the "what."
Examples
Enterprise software implementation: A company issues an RFP for ERP system implementation, asking vendors to propose their implementation methodology, project team composition, training approach, change management support, timeline, and pricing structure. Responses vary significantly in approach, enabling the buyer to evaluate different implementation philosophies.
Contract manufacturing selection: A startup sends an RFP to potential contract manufacturers, requesting proposals covering their manufacturing capabilities, quality systems, NPI process support, engineering resources, capacity planning approach, and commercial terms. The RFP seeks to understand each CM's overall value proposition, not just piece price.
Logistics services: A retailer's RFP for 3PL services asks providers to propose network design, technology platforms, service levels, continuous improvement programs, and pricing models. Responses reveal different operational strategies the buyer hadn't specified.
Definition
RFPs differ fundamentally from RFQs in their purpose and structure. While RFQs assume the buyer knows exactly what they want and seeks the best price, RFPs acknowledge that suppliers may have better ideas about how to meet the buyer's underlying needs. This openness invites innovation but requires more sophisticated evaluation.
Well-structured RFPs clearly describe business objectives, requirements, and evaluation criteria without over-specifying solutions. They typically include background information, scope description, technical requirements, commercial requirements, submission instructions, and evaluation methodology. Providing enough context helps suppliers craft relevant proposals.
RFP evaluation weighs multiple factors beyond price: technical approach, relevant experience, team qualifications, implementation plan, and risk factors. Many organizations use scoring matrices to structure evaluation and document selection rationale.
The RFP process often includes supplier questions, clarification responses shared with all bidders, and sometimes presentations or demonstrations before final selection.
