A cash flow statement tracks the actual movement of money into and out of a business over a defined period. Unlike the income statement, which records revenue when it is earned and expenses when they are incurred (accrual accounting), the cash flow statement records when money actually changes hands. A business can be profitable on its income statement and still run out of cash — if customers pay late, if inventory must be purchased in advance, or if a large expense comes due before revenue arrives.
The statement is organized into three sections. Operating cash flow covers the money generated or consumed by core business activities — customer payments received, supplier invoices paid, wages disbursed. Investing cash flow covers purchases or sales of long-term assets: equipment, vehicles, property. Financing cash flow covers money raised from or returned to investors and lenders — capital contributions, loan proceeds, loan repayments, dividends.
For small and early-stage businesses, the cash flow statement is often more revealing than the income statement. It exposes the timing gaps that cause businesses to fail even when demand exists: the weeks between paying for supplies and receiving customer payment, the seasonal fluctuations that leave cash reserves depleted at the wrong moment, the capital expenditures that front-load costs against future revenue.
