So, although a detailed business plan may not be required for an online business, I am going to include it here so you can at least look at and consider each section and determine yourself if it applies to your business.
Summary Section: This section is where you will be able to attach or explain any detail not applicable to the previous sections. This section should be used to provide the financial statements of the Principle's involved in the business and any other data you think an investor would be interested in seeing.
The main thing to remember in this section is not to provide new data, but to explain in detail data that has already been provided and to provide the support for that data.
The next section, themarketing plan, gets into the details of what your business offers and what market it serves. Marketing is the communication of how your products and services "ease customer pain." Show the problem and how your business solves it. Marketing is a necessity for every business because once your doors are open, you must invite customers to come in. Everything you do in your business that affects customers is marketing because it sends a message about your company.
