A business plan consists of three key financial statements: an income statement, cash flow projection, and balance sheet. The document explains how to prepare these statements by first gathering financial data on startup expenses, operating expenses, revenues, and expenses. It provides details on what each statement covers, such as the income statement showing profits over time, the cash flow projection forecasting cash inflows and outflows monthly, and the balance sheet summarizing assets, liabilities, and equity at a point in time. Preparing these three statements is essential for the financial plan section of the business plan.
