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.
Financial Plan _ The financial plan consists of four sections: Financial Worksheets, Cash Flow Projections, Financial Statements, and Additional Financial Information. All of these components will tell the story of how you plan to start or grow your business from a financial perspective. It is vital that you explain the assumptions under which you have based your projections, for example, "We assume that there are no unforeseen changes in economic policy to make our products and service immediately obsolete." or "We assume interest rates will stay the same over the next three years." (both quotes from Bplans.com sample business plans)
Every Business Needs a Plan _ Without a plan, there is little hope for growth, let alone survival. As my small business development counselor, Terry Chambers says, "If it's not written, it's not real." That doesn't mean it's unchangeable, but it does show that you mean business. In order to accomplish your strategies of improving efficiency, increasing volume, and reorganizing your business, you've got to examine what you have, what you want, and how you plan to get there.
Management and Operations: Because management problems are the leading cause of business failures, it is important to discuss management qualifications and structure. Resumes of the Principals should be included in supporting data. If your business will have few employees and rely heavily on outside professionals, list these key people and their qualifications. If you are seeking financing, include personal financial statements for all of the principals in the supporting data section.
