A business proposal is a written offer from a seller to a prospective sponsor.
Business proposals are often a key step in a complex sales process, where a buyer considers more than price in a purchase.[1]
A proposal puts the buyer's requirements in a context that favors the seller's products and services, and educates the buyer about the seller's capability to satisfy their needs.[2]
There are three distinct categories of business proposals: formally solicited, informally solicited, unsolicited.
