Request for quotation

A request for quotation is a document a buyer sends to one or more vendors, asking each to quote a firm price against a scope, quantity, or specification the buyer has already defined. It differs from a request for proposal, which asks vendors to propose how they would solve a problem rather than simply price a known one. The response a vendor returns typically becomes the starting point for the rate card written into the eventual contract.

1. What is a request for quotation used for?

A request for quotation is used to obtain comparable, firm prices from multiple vendors for a good or service whose specification, quantity, and delivery terms are already fixed. Procurement issues it when the decision left to make is which vendor offers the best price for identical scope, not which vendor has the best approach. The responses feed directly into vendor selection and, for the winner, into the contract's rate card.

Because the specification is fixed before vendors respond, an RFQ produces numbers that can be placed side by side without adjustment. That differs from a request for proposal, where vendors may each propose a different scope, and comparison requires normalizing their approaches first.

An RFQ suits repeatable purchases: freight lanes, MRO items, calibration services, staffing rates. Anywhere the buyer already knows exactly what is being bought, price becomes the only variable worth soliciting.

2. How does an RFQ differ from an RFP or an RFI?

A request for information gathers background on vendor capability with no pricing commitment expected. A request for proposal asks vendors to propose a solution and a price together, for a problem the buyer has not fully specified. A request for quotation skips both steps: scope is already defined, and the vendor is asked only to state a price against it.

Buyers sometimes run all three in sequence: an RFI to identify qualified vendors, an RFP to narrow to a shortlist and approach, then an RFQ to finalize price once scope is locked. On repeat categories the RFI and RFP steps are often skipped because the specification barely changes between purchases.

  • Request for information: Gathers vendor capability and background with no pricing commitment expected.
  • Request for proposal: Asks the vendor to propose an approach and a price for a problem that is not yet fully specified.
  • Request for quotation: States the exact scope and quantity already decided and asks only for a price against it.

3. How does an RFQ relate to the contract's rate card?

The winning vendor's RFQ response is typically carried forward, with minor formatting or term changes, into the rate card attached to the signed contract. That rate card becomes the invoicing reference for the life of the agreement, so the RFQ is effectively the origin document for every unit price the vendor is later expected to bill against.

Because the rate card descends from the RFQ, any gap between the two is worth investigating. Sometimes the gap is a legitimate, documented negotiation outcome. Sometimes it reflects a term that was verbally agreed and never formalized in writing, which leaves the buyer with no enforceable reference if a dispute arises later.

Keeping the RFQ alongside the signed rate card, rather than discarding it once the contract is executed, preserves the ability to trace a disputed price back to its origin.

4. Is a request for quotation legally binding?

A quotation returned in response to an RFQ is generally an offer, not a binding commitment, until the buyer accepts it through a signed purchase order or contract. Vendors can typically revise or withdraw a quote before that acceptance. Once a purchase order or contract references the quoted terms, those terms usually become enforceable. This is general information, not legal advice.

Because bindingness depends on acceptance, the document that matters for a later compliance check is not the RFQ itself but whatever the buyer signed to accept it, and any amendment made afterward.

When an invoice is billed at a rate that differs from the original quotation, the first step is checking whether a signed amendment authorized the change, before treating the difference as an error worth pursuing.

5. Frequently Asked Questions (People Also Ask)

What is a request for quotation in simple terms?

It is a document asking one or more vendors to state a price for a good or service whose specification and quantity are already defined. The buyer compares the quotes and typically selects the lowest qualified price.

How is an RFQ different from an RFP?

A request for proposal asks vendors to propose how they would solve a problem, including scope. A request for quotation already has the scope fixed and asks only for a price against it. RFPs suit undefined problems; RFQs suit known, comparable purchases.

Does the RFQ become part of the final contract?

Not directly, but the winning vendor's quoted price typically carries forward into the rate card attached to the signed contract. Keeping the original RFQ on file lets a buyer trace a rate card price back to what was actually quoted.

Why would a diagnostic review old RFQ documents?

An old RFQ shows the price a vendor quoted before any later renewal, redline, or account change altered terms. Comparing it against the current rate card and against invoices shows whether billed rates still reflect what was originally agreed.

Is a vendor bound by the price in its RFQ response?

Generally not until the buyer accepts the quote through a signed purchase order or contract. Before acceptance, a vendor can usually revise or withdraw the quoted price. This is general information, not legal advice.

What happens if an invoice doesn't match the RFQ-based price?

A mismatch is a compliance question, not automatic proof of overbilling. It needs to be checked against any signed amendment to the original terms before it is treated as an error.

Can an RFQ cover a service, not just a physical good?

Yes. RFQs are used for services with a fixed, known scope, such as calibration, freight lanes, or staffing hours, as readily as for physical goods, provided the specification and quantity are already set.

Who typically issues a request for quotation?

A buyer's procurement or purchasing function issues it, usually to several qualified vendors at once, so responses can be compared on equal terms.
