It's all about the relationship first. Many newbie business owners give a proposal to anyone that they think seems interested in their services. That is an easy way to waste your time. Before you submit a proposal, you should have already developed a strong relationship with the buyer and showed the value that you are going to deliver. Your proposal should be a reiteration of that value and relationship and should only be submitted when you know that you are going to make the sale.
After the Cover Letter and Title Page, add topic pages to show that you understand the position and needs of your boss or prospective client. If your proposal is complex, you might need to begin this section with a brief summary_a page or two that states the most important points you will describe in detail in the following pages. This sort of summary is called an Executive Summary for corporate clients or a Client Summary in a less formal proposal. Your goal in this section is to describe the needs, goals, and desires of your client (i.e., the person who will make the decision about whether or not to accept your proposal). This is not yet the place to talk about what you want to offer. In this section, you must demonstrate that you understand the other party's position and requirements.
