Research framework
Profit is an opinion. Cash flow is a test.
Reported profit depends on accounting choices: when revenue is recognised, how costs are spread over time, and which estimates management uses. Cash is harder to arrange. That is why comparing the two is one of the most useful first checks when reading a company.
The basic comparison
Over several years, operating cash flow should broadly track net profit for a stable business. A persistent gap is not proof of a problem, but it is a question worth asking.
- Profit rising, cash flow flat: where is the money going? Often into receivables or inventory.
- Receivables growing faster than sales: customers may be paying more slowly, or sales terms may be loosening.
- Inventory building up: demand may be weaker than expected, or the business may be stocking for growth.
Questions to ask
- Is the gap between profit and operating cash flow a one-year event or a multi-year pattern?
- Which line in working capital explains it: debtors, inventory, advances or creditors?
- Is the business funding the gap with fresh borrowing?
What this does not tell you
Growing businesses often absorb cash in working capital for good reasons. The point is not to label a company good or bad, but to know which explanation the numbers support and which they do not. Always check the figures against the company's filings.
