Solicited proposals are written in response to published requirements, contained in a Proposal Request, Proposal Requests provide detailed specifications of what the customer wants to buy and sometimes include directions for preparing the proposal. Customers issue Proposal Requests when their needs cannot be met with generally available products or services.
Detailed Proposals are issued to qualified vendors who the company believes can provide desired services.
