Before you can write a synopsis of your business plan, you must write the plan itself in detail. The business plan should provide a description of your company's organizational structure and the products or services it offers. If you create new products, discuss your research and development strategy and any new projects that are in progress. You should also include an in-depth analysis of your industry, your company's sales objectives and its marketing plan. The financial section should list the current state of the company, along with projections for the next several years.
