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.
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.
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.
Explain the fundamentals of the proposed business: What will your product be? Who will your customers be? Who are the owners? What do you think the future holds for your business and your industry?
