A business owner told us last year that his revenue had grown forty per cent and his bank balance had fallen. He assumed someone was stealing from him. Nobody was. He had simply discovered what growth actually costs.

Where the money goes

Every additional rupee of revenue in a goods business absorbs cash in three places before it returns any.

You buy stock earlier. You hold more of it, because a larger order book needs deeper cover. And you wait longer to be paid, because larger customers negotiate harder on terms than small ones do.

Meanwhile your suppliers have not extended you anything extra. So the gap between money going out and money coming back widens exactly when volume rises.

That gap has a name: the cash conversion cycle.

The arithmetic

Cash conversion cycle = inventory days + receivable days − payable days

If you hold stock for 55 days, collect in 40, and pay suppliers in 35, your cycle is 60 days. Every rupee of sales is out of your hands for two months.

Now grow thirty per cent. The cycle does not change, but the amount of money sitting inside it does — by thirty per cent. That increase has to be funded from somewhere, and if it is not funded from a facility it is funded from your bank balance.

This is why a profitable business can fail. Profit is an accounting outcome. Cash is a timing problem.

The three levers

There are only three, and they are not equally easy.

Receivable days is usually the fastest. Most SMEs have never sorted their receivables by age and given each one an owner. Doing that alone frequently recovers ten to fifteen days, because a meaningful share of overdue invoices are not disputed — nobody has asked.

Payable days is a negotiation, not an operation. It is available, but it is finite and it costs relationship capital. Use it deliberately rather than by simply paying late.

Inventory days is the slowest and the most valuable. It requires knowing which stock actually moves, which means the books have to match the warehouse. In trading businesses this is where the largest number usually sits, and it is also the reason a stock reconciliation is almost always the first thing we do.

What a negative cycle means

If payable days exceeds inventory plus receivable days, the cycle goes negative. Your suppliers are financing your operations. This is not a trick — it is how the best-run retail and D2C businesses in India operate, and it is worth understanding as a target rather than an accident.

What to do this month

Calculate the number. Not approximately — actually calculate it, from the books, for the last three months so you can see whether it is moving.

Then pick one lever and work it for a quarter. Businesses that try all three at once usually achieve none, because each one belongs to a different person.
