Cash flow is the movement of money into and out of a business over a period of time. It differs from profit in several important ways.

Profit vs. Cash Flow

Profit

• Measures the difference between revenue and expenses on paper
• Based on accounting records
• Appears on the income statement

Cash Flow

• Measures when cash actually enters or leaves the business bank account
• Focuses on liquidity and available funds
• Appears on the cash flow statement

A business can show a profit while still experiencing cash shortages if customers pay slowly or expenses become due before cash is received.

Why Cash Flow Tracking Matters

Tracking cash flow helps businesses:

• Anticipate shortfalls before they become financial problems
• Determine when they can afford equipment, inventory, or additional staff
• Prepare for taxes and large expenses
• Demonstrate financial health to lenders and investors

Cash flow is generally analyzed through three areas:

• Operating activities
• Investing activities
• Financing activities
