growth vs. cash
Growth spends cash faster than it makes it.
Ask a promoter how the business is doing, and most will point to the same number: revenue is up. Twenty per cent this year, thirty the year before. The P&L looks healthy. The story sounds right. And then, with almost no warning, the same business is unable to make payroll on time — not because it isn’t profitable, but because it’s out of cash.
This isn’t a contradiction. It’s one of the most common and least understood failure patterns in growing mid-market businesses. Growth doesn’t just fail to prevent a cash crisis. In a lot of cases, growth is precisely what causes one.
Profit and cash are not the same conversation
The confusion starts with a basic accounting reality that gets lost in the excitement of a growing top line. Profit is a measure of what you’ve earned, on paper, once revenue is recognised and costs are matched against it. Cash is what’s actually sitting in the bank, available to pay a supplier or a salary today. A business can be genuinely, honestly profitable by every accounting standard and still be unable to cover this month’s expenses — because the profit exists on invoices that haven’t been paid yet, in inventory that hasn’t been sold yet, or in receivables sitting with customers who are in no hurry.
Growth makes this gap wider, not narrower, because growth multiplies everything that sits between “we made the sale” and “we have the money.” More orders means more inventory purchased upfront. More customers means more receivables outstanding at any given time. More activity means more people, more suppliers, more overheads — all of which need to be paid now, while the revenue they generated is still working its way through the system.
The mechanism, made concrete
Picture a business growing revenue at a healthy clip. To fulfil that growth, it has to buy more raw material or stock before the sale happens — cash goes out. It sells to customers on 60- or 90-day terms, which is standard in a lot of mid-market B2B relationships — cash comes in much later than the sale is recorded. Meanwhile, payroll, rent, and supplier payments don’t wait for customer terms; they’re due on their own schedule, every month, regardless of how the receivables are ageing.
At a small scale, this gap is manageable — the business has enough of a buffer to absorb the lag. But as revenue grows, the absolute size of that gap grows with it. A business growing 30% a year isn’t just doing 30% more of everything that generates profit — it’s also carrying 30% more inventory, 30% more receivables, and 30% more of the timing mismatch between spending and collecting. Nobody budgeted for that, because nobody was looking at working capital as a function of growth. They were looking at the P&L, which looked better every quarter, right up until the bank balance told a very different story.
Why this catches good businesses off guard
The businesses this happens to aren’t badly run. They’re often the opposite — growing fast, winning customers, genuinely improving their market position. That’s exactly why the warning signs get missed. Nobody scrutinises a growth story that looks this good. The monthly management review celebrates the revenue number and moves on, because revenue is the metric everyone in the room instinctively understands and feels good reporting.
Working capital, by contrast, is unglamorous and technical — days sales outstanding, inventory turns, the cash conversion cycle. It doesn’t get celebrated in a board meeting the way a revenue milestone does, so it doesn’t get tracked with the same discipline, even though it’s the metric that actually determines whether the business can survive its own success.
What actually protects against it
The fix isn’t slower growth — for most ambitious mid-market businesses, that’s not a realistic answer, and it isn’t the right one either. The fix is treating cash and working capital as a tracked discipline with the same seriousness as revenue, not an afterthought that gets reviewed once the crisis has already started.
Forecast cash separately from profit, on a rolling basis. A monthly or even weekly cash flow forecast — not a P&L projection — is the single most effective early warning system available. It shows the crunch coming months before it arrives, while there’s still time to act, rather than the week it becomes an emergency.
Know your cash conversion cycle as a number, not a feeling. How many days, on average, does it take from spending cash on inventory or delivery to actually collecting cash from the customer? Most promoters can describe this qualitatively — “customers pay us kind of slowly” — very few can state it as a number they track monthly. The number is what lets you see it getting worse before it becomes unmanageable.
Fund growth deliberately, not by accident. Growing working capital needs either internal cash reserves, a credit facility, or supplier and customer terms renegotiated to close the gap — and that decision should be made ahead of the growth, as a deliberate financing choice, not discovered retroactively when the account runs dry.
The reframe worth internalising
A rising revenue line is not, by itself, evidence of a healthy business. It’s evidence of a growing business — and growing businesses have a specific, well-understood way of running out of cash that has nothing to do with whether they’re actually good businesses. The promoters who avoid this crisis aren’t the ones who grow more cautiously. They’re the ones who watch the cash conversion cycle with the same discipline they watch the top line, so growth never becomes the thing that quietly bankrupts them.
If your revenue is growing faster than your comfort with the bank balance, that gap is worth measuring properly before it becomes a crisis. See how our Finance & Governance practice works →
