A cash flow statement reconciles your profit to the actual movement in your bank balance, split across three activities: operating, investing and financing. It is the statement that explains how a profitable business can run out of money, and how a loss-making one can be flush. The income statement tells you whether you made money. The cash flow statement tells you where it went.
Most small business owners have seen an income statement and a balance sheet. Very few have ever had the third one explained.
Why does profit not equal cash?
Because the income statement records revenue when earned and costs when incurred, regardless of when money moves.
Six things sit between profit and cash, and every one of them appears in the cash flow statement:
| What | Effect on cash |
|---|---|
| Debtors increase | You invoiced it. They have not paid. Profit up, cash down |
| Stock increases | Money converted into goods on a shelf. No profit effect, cash gone |
| Creditors increase | You have the goods, have not paid. Cash preserved, temporarily |
| Depreciation | A cost with no cash movement. Profit down, cash unaffected |
| Buying an asset | Cash out, but only the depreciation hits profit |
| Loan repayments | Capital repaid does not touch profit. Cash out, invisible on the P&L |
That last row is the one that catches people. A business repaying R40,000 a month of loan capital sees the interest on the income statement and nothing else. The capital simply leaves, and the P&L never mentions it.
See why your bank balance is not your profit.
The three sections
Operating activities
Cash generated by the actual business — customers paying, suppliers and staff being paid, tax.
This is the most important number in the statement. A business that does not generate cash from operations is being funded by something else — borrowings, asset sales, or the owner. None of those is sustainable.
It starts with profit and adjusts for non-cash items (depreciation, provisions) and for movements in working capital (debtors, stock, creditors).
Investing activities
Cash spent on or received from long-term assets — buying equipment or vehicles, selling them.
Negative here is usually healthy. A business investing in its capacity should be spending. Consistently positive investing cash flow can mean the business is selling assets to survive, which is worth noticing early.
Financing activities
Cash from and to funders and owners — loans drawn and repaid, capital introduced, dividends paid.
This is where loan capital repayments appear — the amounts your income statement never showed you.
What the pattern tells you
Read the three together. The combination is diagnostic.
| Operating | Investing | Financing | What it usually means |
|---|---|---|---|
| Positive | Negative | Negative | Healthy. The business funds itself, invests, and repays debt |
| Positive | Negative | Positive | Growing, funded partly by borrowing. Fine if operating cash is rising |
| Negative | Negative | Positive | Burning cash and borrowing to do it. Sustainable only briefly |
| Negative | Positive | Negative | Selling assets to pay the bills. The most serious pattern here |
| Positive | Positive | Negative | Possibly winding down, or disposing of something significant |
The fourth row deserves attention. A business showing an operating outflow funded by asset disposals is consuming itself, and it can look calm on an income statement for a surprisingly long time.
The scenario people ask about
"We made a profit. Where is the money?"
A simple illustration. Profit for the year, R600,000.
| Profit for the year | R600,000 |
| Add back depreciation (no cash) | +R150,000 |
| Debtors increased | −R400,000 |
| Stock increased | −R250,000 |
| Creditors increased | +R100,000 |
| Cash from operations | R200,000 |
| Bought equipment | −R300,000 |
| Loan capital repaid | −R180,000 |
| Net movement in cash | −R280,000 |
R600,000 of profit, and the bank balance fell by R280,000. Nothing here is an error and nothing is unusual — it is a growing business funding debtors and stock while repaying a loan.
The income statement cannot show you this. The cash flow statement shows exactly which three lines caused it: debtors, stock, and loan capital.
And it tells you what to do — chase debtors harder, hold less stock, or refinance the loan over a longer term. See what is working capital and how to get customers to pay you on time.
Historic statement or forward forecast?
Two different tools, and you want both.
The cash flow statement is historic. It explains what happened, and it forms part of the annual financial statements where the company prepares them. It is diagnostic.
A 13-week cash flow forecast is forward-looking. It shows what is about to happen, week by week, and it is what actually prevents a crisis. It is operational.
The statement tells you why last year went the way it did. The forecast tells you whether you can pay salaries in six weeks. See how to build a 13-week cash flow forecast.
Most small businesses have neither, and the forecast is the more urgent of the two.
Do I have to produce one?
Where your company prepares annual financial statements in accordance with a financial reporting framework, a cash flow statement is ordinarily one of the required components — alongside the income statement and the balance sheet.
Whether your company must prepare financial statements at all, and to what standard, depends on your public interest score and your MOI. See what are annual financial statements and does your company need them and how to calculate your public interest score.
But the more useful answer is that you should want one regardless. A business owner who has never seen where their cash went is managing on one instrument.
Frequently asked questions
What is a cash flow statement? A financial statement reconciling profit to the actual movement in cash, split across operating, investing and financing activities. It shows where the money went, which the income statement cannot.
Why is my profit different from my bank balance? Because profit records revenue when earned and costs when incurred, not when money moves. Increases in debtors and stock consume cash without affecting profit, depreciation reduces profit without using cash, and loan capital repayments use cash without appearing on the income statement at all.
What are the three sections of a cash flow statement? Operating activities — cash from the actual business. Investing activities — buying and selling long-term assets. Financing activities — loans, capital introduced and dividends paid.
Which section matters most? Operating. A business that does not generate cash from its operations is being funded by borrowing, asset sales or the owner, and none of those lasts.
What does it mean if operating cash flow is negative but investing is positive? Usually that the business is selling assets to pay its bills. It is the most serious pattern in a cash flow statement and it can look calm on an income statement for a long time.
Why do loan repayments not show on my income statement? Only the interest does. Repayment of loan capital is a financing cash flow — it reduces your bank balance and a liability, and never touches profit.
Is a cash flow statement the same as a cash flow forecast? No. The statement is historic and explains what happened. A forecast is forward-looking and shows what is about to happen. You want both, and the forecast is the more urgent.
Does my company have to produce one? Where your company prepares annual financial statements under a financial reporting framework, a cash flow statement is ordinarily required. Whether financial statements are required at all depends on your public interest score and MOI.
The third statement is the one that explains the other two
An income statement tells you whether the year worked. A balance sheet tells you what you are standing on. Only the cash flow statement tells you why the bank balance did what it did — and that is usually the question the owner is actually asking.
Smartbook produces monthly management accounts including the cash flow position, so you can see where the money is going while you can still do something about it — rather than reading it in a statement eight months after year end.
