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.
Competitive Analysis: Business by nature is competitive, and few businesses are completely new. If there are no competitors, be careful; there may be no market for your products. Expand your concept of competition. If you plan to open the first roller skating rink in town, your competition will include movie theaters, malls, bowling alleys, etc.
