A business plan should be detailed. In listing your products and services for example, you should not really stop by just enumerating them. You also should write down the descriptions and scope of your products and services, touch base on production and identify means on how you can market your "brain - child" to your targeted niche.
Financial Plan- This is the most important part of the business plan where you need to show the three year projection of the projected financial statements, including income statements, pro-forma balance sheets, and monthly cash flow and annual cash flow statements which will help in forecasting your revenues and expenses.
Basic Business Information : Here you will list basic information about your business. This should include the hours of operation, how long you have been in business, your contact details such as your phone number, email address and website. This does not need to be extensive but should cover the essentials of your business operation.
Once you have done all this you should have a complete and detailed professional business plan. The most important thing to remember when developing the plan is to see it as a living document and include specifics regarding dates and specific responsibilities. Your plan will need constant reviews and updates and things change so expect it to be a work in process for a good stretch of time. It will all be worth it in the end, a well-written plan will help ensure that the business is fully focused on what is required to achieve the company's goal.
