- What cash flow actually means
- Why profitable businesses still run out of cash
- How to read a cash flow statement

- Tools that make cash flow management easier
If you run a small business, mastering cash flow is not optional — it’s survival.
What Is Cash Flow in a Small Business?
Cash flow is the movement of money in and out of your business.
- Money coming in = cash inflow
- Money going out = cash outflow
When inflows exceed outflows → positive cash flow
When outflows exceed inflows → negative cash flow
Unlike profit, cash flow focuses strictly on actual money movement, not accounting entries.
Cash Flow vs Profit: Why They’re Not the Same
This is one of the most common misunderstandings in small business finance.
You can show a profit because:
- You made sales
- You recorded revenue
But you might not have received payment yet.
Meanwhile, you still must pay:
- Rent
- Payroll
- Suppliers
- Taxes
That gap creates cash flow stress.

The 3 Types of Cash Flow
Understanding these categories helps you analyze your financial health.
1) Operating Cash Flow
Cash generated from core business activities:
- Customer payments
- Supplier payments
- Operating expenses
This is the most important type for sustainability.
2) Investing Cash Flow
Cash spent on or received from:
- Equipment purchases
- Asset sales
- Investments
Usually negative in growing businesses.
3) Financing Cash Flow
Cash from:
- Loans
- Investor funding
- Owner contributions
Or cash used to:
- Repay debt
- Pay dividends
These three sections form your cash flow statement.
Why Small Businesses Struggle with Cash Flow
Common causes include:
- Late customer payments
- High inventory costs
- Over-expansion
- Poor forecasting
- Weak expense control
- Seasonal revenue swings
- Rapid hiring
Cash flow problems are rarely caused by one issue — they’re usually systemic.
How to Read a Cash Flow Statement (Simple Version)
Your cash flow statement shows:
- Operating cash flow
