There are two main reasons to write a business proposal. Either someone has invited you to submit a RFP (Request for Proposal); or you are trying to gain support or funding from your employer or another organization.

When drafting a proposal the most important thing to keep in mind is that the reader is looking for benefits; they want to know how your product, service, or idea adds value to their operation. Therefore your proposal must be well-written and it also must clearly indicate how you can fulfill a current need.
