While all business plans share the common objective of describing a businesses purpose and structure, analyzing the marketplace, and creating cash flow projections, the types of plans differ. There are three major kinds.
The mini plan. This is a shorter plan (likely 10 pages or less), and is useful for determining potential interest in your business, further exploring a concept, or starting point to a full plan. This is a great starting point.  The working plan. This can be considered the full version of the miniplan, and its main purpose is to outline, without emphasis on appearance, precisely how to build and operate the business. This is the plan that the business owner would refer to regularly as the business moves towards its objectives. The presentation plan. The presentation plan is meant for individuals other than those owning and operating the business. This could include potential investors or bankers. It is essentially the working plan, but with an emphasis on sleek, marketable presentation, and proper business language and terminology. Whereas the working plan is made for reference by the owner, the presentation needs to be written with investors, bankers, and the public in mind.
