Overtrading: How Growth Itself Can Bankrupt A Profitable Business
Here is something that can appear confusing at first: a business can be busy, profitable, and growing, and still run out of cash. Not despite the growth. Because of it.
The core truth underneath this is simple, even if it doesn’t feel that way when you’re living through it. Lack of cash, not lack of profit, is what actually destroys a business. Plenty of profitable businesses have failed for exactly this reason, and plenty of struggling ones have survived simply because they managed their cash carefully.
Profit and cash are not the same thing, and growth is precisely the moment that gap widens fastest.
The working capital cycle
Every business has a gap between paying its own costs and getting paid by its customers. You pay suppliers, you pay wages, you deliver the work or the stock, and only later does the customer's payment come in. That gap is your working capital cycle, and it needs funding somehow, either from cash you already hold or from a facility that bridges it.
Growth widens this gap on every side at once. More stock or work in progress is tied up at any given moment, because you are doing more of it.
A longer wait to get paid, because more customers means more invoices sitting in the pipeline before payment.
And often, larger supplier bills arriving sooner, because growth usually means buying more, and buying it before the corresponding sales revenue has actually come in.
The signs to watch
On their own, these things seemingly don’t pose too much of a problem, but that is exactly what makes overtrading dangerous; it creeps up on you.
Profit looking healthy on the P&L while the bank balance feels permanently tight.
Debtor days quietly stretching, invoices taking longer to be paid than they used to, often without anyone deciding that should happen.
Stock or work in progress building up faster than sales are converting into cash.
A growing reliance on an overdraft or facility just to cover the ordinary rhythm of the month, rather than for one-off pinch points.
A nagging, hard-to-place feeling that the business should feel more comfortable than it does, given how well things appear to be going.
Why profit on the P&L can mask a cash problem
The profit and loss account records a sale the moment it’s made, or the moment work is delivered, regardless of when the cash actually lands. A business can show a genuinely healthy profit for the month while the cash from that same work is still weeks away, tied up in a customer's payment terms, and meanwhile new costs to fund the next round of growth are already going out. The P&L tells you the business is working. It doesn’t tell you whether the business has the cash, right now, to keep operating while it waits to be paid for the work it has already done.
It’s manageable…if you see it coming
None of this means growth is dangerous, or that you should slow down out of caution. Growth funded and managed properly is exactly how a good business should scale. The businesses that come unstuck are the ones who didn’t t see the gap widening until it had already become a real cash crisis.
Watch the working capital cycle as closely as you watch the P&L, particularly through any period of real growth.
If debtor days are stretching, chase it. If stock is building, question why.
If the overdraft is doing more day-to-day work than it used to, understand precisely why before it becomes the only thing holding the month together.
Seen early, this is simply something to plan around. Seen late, it’s a crisis. The difference is almost entirely a matter of when you started paying attention.
