Let’s start with something that sounds completely wrong.
A business can be profitable… and still go bust.
Not struggling. Not underperforming. Not “on the edge.”
Actually fail.
At first glance, that doesn’t make sense. If a company is making a profit, surely it’s doing well? Surely it has money?
Not necessarily.
Because profit and cash are not the same thing, and confusing the two is one of the most common (and dangerous) mistakes in business.
The illusion of profit
Profit is what you see on the income statement. It’s calculated using accounting rules designed to show performance over a period of time.
Cash is what’s actually sitting in your bank account.
And the gap between those two can be huge.
Imagine you run a business that sells products to corporate clients. You land a big contract worth £100,000. Great news. You deliver the goods, send the invoice, and record the sale.
On paper, your profit jumps.
But here’s the catch: your customer has 60 days to pay.
So today, your profit has increased, but your cash hasn’t.
Now imagine that happens again. And again. And again.
You’re growing fast. Sales look fantastic. Profit is rising.
But your bank balance? Not so much.
In fact, you might be running dangerously low on cash without even realising it.
"We’re profitable… so why are we struggling?”
This is exactly the situation many businesses find themselves in.
Take fast-growing startups, for example. It’s common to see headlines about companies with booming sales suddenly collapsing.
A classic issue is what’s called a cash flow squeeze.
They might be investing heavily in growth. For example, hiring staff, expanding into new markets, or launching new products. All of that costs cash, often upfront.
But the cash from customers comes later.
So even though the business looks successful on paper, it runs out of money in reality.
Retailers are particularly vulnerable to this. Many have reported strong sales growth and decent profits, but still ended up in administration because they couldn’t manage their cash flow especially when suppliers needed paying before customers had settled their bills.
It’s not that the business model didn’t work.
It’s that the timing didn’t work.
Not all expenses are “real” cash costs
Another reason profit and cash differ is that some costs in accounting don’t involve any cash at all.
Depreciation is the classic example.
If a company buys a machine for £50,000, it doesn’t expense the full amount immediately. Instead, it spreads the cost over several years.
So each year, it might record £10,000 as an expense.
That reduces profit but no cash is leaving the business at that point. The cash went out when the machine was bought, possibly years earlier.
So again, profit is being reduced… but cash isn’t.
The silent killer: working capital
If you really want to understand why businesses run out of cash, you need to look at something called working capital.
Don’t worry about the jargon, it’s just about timing.
It comes down to three things:
- How quickly customers pay you
- How quickly you pay suppliers
- How much cash is tied up in inventory
If customers take a long time to pay, that’s cash stuck outside the business.
If you have lots of inventory sitting in a warehouse, that’s cash you’ve already spent but haven’t yet recovered.
If suppliers want paying quickly, cash leaves the business faster than it comes in.
Put all of that together, and you can have a profitable business that is constantly short of cash.
This is why you’ll often hear the phrase:
“Profit is vanity, cash is reality.”
It’s a bit dramatic but not wrong.
Why investors don’t just look at profit
If you were investing in a company, would you only look at profit?
Hopefully not.
Because experienced investors know that profit can sometimes give a misleading picture.
That’s why they look at cash flow statements as well.
These show how much cash is actually being generated, whether profits are turning into cash, and whether the business is relying on borrowing to survive.
If a company reports strong profits but weak cash flow, it raises questions.
Are customers not paying?
Is the business growing too fast?
Is it over-investing?
These are exactly the kinds of issues that can turn a “successful” company into a failing one.
Bringing it back to you (and your exams)
If you’re studying accounting or business, this isn’t just theory. It’s something examiners love to test.
You might be asked to explain why a profitable business is facing liquidity problems.
Or to analyse financial statements and identify risks.
And the students who stand out are the ones who go beyond saying “profit is up” and start asking:
“But where is the cash?”
Because that’s the real question.
Final thought
If you take one idea away from this, make it this:
A business can survive without profit for a while.
It cannot survive without cash.
Profit tells a story about performance.
Cash tells the truth about survival.
And in business (as in exams) knowing the difference can change everything.
