Three procurement terms, three different buying questions
RFQ, RFP and tender are sometimes used loosely, but each usually signals a different buyer need. The title alone does not determine the process: always read the document, because organisations may use terminology differently. The useful distinction is what the buyer wants to compare and what the supplier must prove.
| Process | Main buyer question | Typical supplier response | Often useful when |
|---|---|---|---|
| RFQ | What will you charge for a clearly defined requirement? | Quotation, delivery details and requested compliance information | Scope and specification are relatively clear |
| RFP | What solution do you propose, and why will it work? | Methodology, team, work plan, evidence and price | The buyer needs to compare approaches |
| Tender / ITT | Can you meet the formal requirement on the stated terms? | Structured technical, compliance and financial submission | A formal competitive process is required |
Request for Quotation: focus on a defined requirement
An RFQ commonly asks suppliers to price specified goods, works or services. The buyer may provide quantities, specifications, delivery points and a response form. Suppliers should confirm that the quotation covers the full requirement, state permitted assumptions, check validity and delivery timing, and include every document requested.
An RFQ is not automatically informal. It can still contain mandatory conditions and a strict deadline. Do not send only a price when the request also asks for compliance evidence or technical specifications.
Request for Proposal: explain the solution
An RFP commonly gives suppliers more room to propose an approach. The buyer may describe an outcome, problem or terms of reference and assess methodology, personnel, experience, risk and price. A credible proposal connects each part of the approach to the buyer’s objective and explains how delivery will be controlled.
For example, an RFP for a digital records system may compare solution design, implementation, training, support, security and commercial terms—not simply the cost of software licences.
Tender or Invitation to Tender: follow the formal structure
A tender or ITT normally invites competitive responses against a defined scope and formal instructions. It may include eligibility, technical specifications, forms, pricing schedules, contract terms and an evaluation method. Suppliers should create a compliance matrix and avoid changing the buyer’s requested structure without good reason.
How suppliers should adapt
- For an RFQ, make the price accurate, complete and easy to compare.
- For an RFP, show understanding, a workable method and evidence that your team can deliver.
- For a tender, treat compliance and submission control as seriously as the solution itself.
In every case, check whether clarification questions are allowed, monitor amendments and submit through the stated channel. Never infer a legal requirement from the document label alone.
Example: office equipment
A buyer that knows the exact laptop specification and quantity may issue an RFQ. A buyer seeking a managed workplace technology service may issue an RFP because suppliers could propose different operating models. A large, formally advertised supply requirement may use an invitation to tender with detailed eligibility and contractual documents.
Frequently asked questions
Is an EOI the same as an RFP?
No. An expression of interest often helps a buyer identify capable organisations or create a shortlist before a later procurement stage. Follow the document’s specific instructions.
Which process gives suppliers the most freedom?
An RFP often allows more solution design than a tightly specified RFQ, but the actual freedom depends on the buyer’s requirements and evaluation criteria.
Read the question behind the label
The best response is shaped by the buyer’s decision: price comparison, solution comparison or formal compliance with a tender requirement. Explore current opportunities and use this distinction when deciding how much technical and commercial detail to prepare.
