Cash flow tracks actual cash moving in and out — from operations, investing and financing — over a period. A business can be profitable on paper yet run out of cash if receivables are slow or stock ties up funds, which is why cash flow is watched separately from profit.
Forecasting cash flow helps a business anticipate shortfalls and plan purchases, payments and credit.
Operating cash flow is usually derived indirectly: start with profit, add back non-cash charges such as depreciation, then adjust for working-capital movements — rising debtors and stock absorb cash, while rising creditors release it. Suppose a firm earns ₹5,00,000 profit with ₹1,00,000 depreciation, but debtors grow by ₹3,00,000 and stock by ₹2,00,000. Operating cash flow is just ₹1,00,000, a fraction of the reported profit.
Indian businesses feel timing pressure acutely. GST on outward supplies falls due on an invoice basis, so tax can be payable before the customer has paid, funded from the firm's own pocket. Festival trade compounds this: stocking for Diwali means cash flows out to suppliers weeks before sales convert back into collections, and firms that ignore this seasonal gap run short precisely when trade is at its busiest.
The common analytical mistake is treating the bank balance as the whole story. A comfortable balance today may already be committed to loan instalments, salaries, GST and TDS deposits due within the fortnight. The cash conversion cycle — the days between paying for stock and collecting from customers — is a steadier lens, and shortening it through faster billing and tighter credit does more for liquidity than any single cost cut.
