Cash flow: why profitable businesses run out of cash

Financials

A business can be profitable on paper and have no money to pay salaries at the end of the month. It’s not a paradox — it’s the most common way healthy businesses go under.

Profit and cash aren’t the same thing. Profit is an accounting concept; cash is what’s actually in the account. You can have the first without the second — and that’s when the problems start.

How a profitable business runs out of cash

Imagine you sell products with a good margin. On paper, you’re making money. But:

• You pay your suppliers in 30 days, while your customers pay you in 90.
• You bought inventory that’s sitting in the warehouse and hasn’t sold yet.
• You invested in equipment that will depreciate over years, but you paid for it today.

Each of these can be right in the long run. But together they drain cash now. The result: profit on paper, a hole in the bank.

The three liquidity traps

1. The receipts–payments mismatch

When you pay before you collect, you’re essentially financing your customers. The faster you grow, the bigger the hole gets.

2. Growth without liquidity

Paradoxical but true: many businesses close because they grew too fast. Every new order requires capital for inventory and staff — before the money comes in.

3. The “invisible” inventory

Inventory looks nice on the balance sheet, but it’s cash frozen on shelves. As long as it sits there, it isn’t working for you.

What to track instead of profit

• 13-week cash forecast. How much cash comes in and goes out each week — not each year.
• Cash conversion cycle. How many days pass from when you pay to when you collect.
• Safety margin. How many months you can last if collections stopped tomorrow.

Profit is an opinion. Cash is a fact.

How you take control

Controlling liquidity isn’t an accounting matter — it’s a management one. It means looking ahead with a forecast, negotiating payment terms that favour you, not freezing capital in unnecessary inventory, and knowing at any moment how much runway you have left.

You don’t need complex tools. You need a system that shows you the truth in time — not three months later, when it’s already too late.

How we approach it

We set up simple cash-oversight systems: a forecast that’s easy to update, indicators you can see at a glance, and rules that protect the bank as you grow. Not theory — the same tools we use to keep our own businesses healthy.
