Which document types are categorized as solicitations?

The categorization of documents as solicitations is specifically tied to the methods used by organizations to invite bids or proposals from potential suppliers or contractors. Among the choices provided, Request for Proposals (RFP), Request for Quotations (RFQ), and Request for Bids (RFB) are all recognized types of solicitation documents.

An RFP is used when the organization is seeking creative proposals for a project or service and is open to receiving a variety of approaches. An RFQ, on the other hand, is generally aimed at obtaining price quotes for specific goods or services, allowing for price comparisons. An RFB is primarily utilized when the organization is requesting sealed bids, typically for construction or large projects, where the focus is on receiving fixed-price offers.

The other options present document types that do not fit the solicitation category. Proposal letters and meeting notes relate to internal communications or responses but do not serve as official solicitation documents. Reports and invoices are typically post-award documents that detail outcomes or costs and do not solicit proposals. Contracts and extensions represent agreements already formed, rather than invitations to provide bids. Therefore, the group including RFP, RFQ, and RFB accurately reflects the solicitations used in contracting practices.
