Three Forms most commonly used by Purchasing Professionals (updated 2025)

Procurement Forms by RFQPro

In order to manage procuring supplies and services, a purchasing professional utilizes various forms. The three most commonly used forms are the Request for Proposal (RFP), Request for Quotation (RFQ), and Invitation to Bid (ITB). There are also many other forms available.

Request for Proposal (RFP)

The RFP is now the most commonly used form for procurement or purchasing personnel. While it is often used for straightforward purchases—which may be overkill and potentially problematic—it does have its place. In many cases, the RFP is the best document for the job.

RFPs are ideal for situations such as:

  • Seeking an expert to provide a solution to a need, where proposals may vary.
  • When there is a detailed scope of work involving equipment and labor.
  • Other scenarios requiring flexibility or complex evaluation criteria.

Keep in mind that an RFP is subject to interpretation. Therefore, ensure the scope is very clear. If it is your first time drafting an RFP, avoid starting from scratch. Mistakes are more likely to occur, so use templates, examples, or models to guide the initial development.

Request for Quotation (RFQ)

Some argue that the RFQ is becoming obsolete, replaced by the RFP. However, the RFQ remains a better option when purchasing commodities with little room for alternatives. For instance:

  • When there is a specific description, part number, unit of measure, and quantity needed. For these straightforward purchases like: “We need 10 XYZ widgets so please provide price and delivery details for these 10 XYZ widgets.”

The RFQ simplifies the process for such clear-cut needs.

Invitation to Bid (ITB)

The ITB is another procurement form widely used today. Similar to an RFQ, it is an invitation for a supplier to offer a product or service for a specific cost. However, the ITB is more formal and typically includes a set of conditions attached to the bid document. If the buyer accepts the supplier’s bid, the conditions become part of the acceptance agreement.


Evolution of the RFP

While most procurement forms are relatively straightforward, the RFP has evolved significantly since its introduction in the early 1980s. RFPs have become increasingly prevalent and refined over time. Regardless of the form chosen, companies that purchase goods and services rely on procurement forms to manage their business effectively. These forms are particularly useful when selection criteria include factors beyond price, such as service capabilities or technical support.


Role Players in the RFP/RFQ Process

To clarify the roles involved in the RFP or RFQ process, here are the key participants:

  1. Tenderer (Supplier/Offeror/Vendor/Bidder): The seller of materials or supplies who submits a proposal or quotation based on the buyer’s requirements.
  2. Owner/Buyer: The party responsible for paying the invoice submitted by the supplier.
  3. User/Internal Department: The department that developed the scope of work or originally made the procurement request.
  4. Purchasing Agent/Procurement Officer: The individual managing the RFP/RFQ process.

Other participants may be involved, but these are the primary roles relevant to this discussion.
