Start by writing a description of your business, including what stage of development it is currently in (conception, start_up, first year, mature, exit) and your plans for growth. Discuss the nature of your business, the main products and services you offer, the market for your products and services, and how and by whom the business is operated.
An income statement shows revenues minus expenses, in order to calculate net income or net loss. Start_ups should project these expected results for the first twelve months of business, then quarterly for the next two years. A list of a company's assets (what you own), liabilities (what you owe), and net worth (assets minus liabilities) is called a balance sheet. The statement of owner's equity shows the owner's initial investment, additional investments, and retained earnings, minus owner withdrawals.
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."
