Which procurement document indicates a buyer's needs for products but also requests cost estimates?

The procurement document that indicates a buyer's needs for products while also requesting cost estimates is the Request for Quote. This document is specifically designed to solicit price quotes from suppliers based on the products or services the buyer intends to purchase.

When a buyer issues a Request for Quote, they typically outline the specifications and requirements needed for the products, allowing suppliers to provide detailed pricing information. This process helps the buyer evaluate different options based on cost as well as compliance with their requirements.

The Request for Information is primarily aimed at gathering general information from potential suppliers, without a focus on cost. The Request for Proposal goes a step further by not only seeking pricing but also requiring detailed proposals that include a supplier's approach to fulfilling the buyer's needs, which may often include technical aspects, qualifications, and timelines. The Request for Purchase, on the other hand, is the actual order document used after the purchasing decision has been made, and does not serve the function of estimating costs.
