the business that grows on its suppliers' money

Two companies crossed my desk last week with almost identical income statements. Same revenue, same margin, both growing nicely. One of them spent the whole year scrambling for cash and topping up a working capital loan. The other generated more and more cash the faster it grew. Same profit on paper, two completely different lives. The difference was not in the profit line at all.

It was in the cash conversion cycle. Take the days a company waits to collect from customers, add the days its stock sits in inventory, subtract the days it takes to pay its own suppliers. That number is how long the company's cash is locked up before it comes back.

Company A collects in 75 days, holds inventory for 90, and pays suppliers in 30. That is 135 days of its own money tied up in every cycle. Company B is the mirror image. Customers pay it upfront in 5 days, stock moves in 20, and it takes 60 days to pay suppliers. Its cycle is minus 35 days. The suppliers and the customers are funding the business for it.

Here is where it bites. Grow each one by Rs 100 crore of sales. Company A has to find Rs 37 crore just to fund the extra inventory and the invoices customers have not paid yet. Company B is handed roughly Rs 10 crore of spare cash for the same growth. A Rs 47 crore swing, and you will not find a hint of it on the profit line.

This is why some of the steadiest compounders barely borrow. A negative cycle is a free loan that scales with them. And it is why a quietly rising collection-days number, year after year, is worth more of your attention than one good quarter. The one that collects first and pays last rarely has to call the bank to grow
