Imagine you run a small business making custom wooden furniture. A large corporate client orders 100 desks for ₹10 lakh. You deliver the desks, send them an invoice, and give them credit terms to pay you after six months. On your ledger, you write down a splendid sale. Your books show a fat profit. But when you go to pay your wood suppliers and craftsmen at the end of the month, your bank account is empty. You cannot pay them with an invoice.

This is the classic gap between paper profit and real cash. In the stock market, thousands of retail investors fall into the trap of looking only at a company's growing net profit without checking if any actual cash is entering the bank.

The Illusion of Accrual Accounting

Indian businesses use accrual accounting. Under this system, revenue and profits are recorded the moment a sale is made, not when the cash is received. If a company sells goods on credit, its Net Profit (often called Profit After Tax or PAT) goes up immediately.

However, that unpaid money sits on the balance sheet as Trade Receivables (money owed by customers). If a company is aggressively pushing goods to distributors on easy credit terms just to make its sales look good, its profits will soar, but its bank balance will dry up. A business can survive for a while without profits, but it will collapse instantly without cash.

The Ultimate Truth Test: CFO vs. Net Profit

To find out if a company's profits are real or just paper promises, you must compare Net Profit with Cash Flow from Operations (CFO). CFO is the actual net cash that entered or left the company's bank accounts from its core business activities.

In any single year, CFO and Net Profit can differ due to temporary factors like inventory buildup. But over a block of three to five years, they must move in tandem. If Net Profit keeps rising year after year while CFO stays flat or drops, it is a major red flag.

Look at the fictional table above for a business called Vibrant Paints. On paper, the business looks spectacular. Net profit doubled from ₹10 Crores to ₹20 Crores. But look at the CFO—it plummeted into the negative. Why? Because the Trade Receivables ballooned from ₹4 Crores to ₹32 Crores. The company is selling paint, but nobody is paying them.

How to Run the Cumulative Cash Check

You can easily run this check yourself on any company using a simple three-step calculation over a multi-year period.

For Vibrant Paints, the calculation is: ₹9 Crores ÷ ₹45 Crores = 0.20 (or 20%).

This means that over three years, only 20% of the profits reported by the company actually turned into cash. The other 80% is just an 'opinion' written on paper. A healthy, self-sustaining business should ideally convert at least 80% (a ratio of 0.80 or higher) of its net profits into operating cash over any 3-to-5-year block.
