7 early warning signs of a cash flow crunch

Cash flow problems rarely arrive without warning. They build over weeks while the business looks fine on paper. The owners who cope best are the ones who recognise the signals early, while they still have options — because options get expensive once you are down to your last two weeks of runway.

Here are seven signs worth watching, and what to do about each.

1. You are checking your bank balance daily

This sounds like diligence. It is usually anxiety. If you need to know the balance before approving routine payments, you are managing to the balance rather than to a plan — a reliable early indicator that the buffer has thinned.

The fix is a rolling 13-week cash flow forecast. It converts a vague worry into specific dates, which is what makes a problem solvable.

2. Receivable days are creeping up

If customers who used to pay in 30 days now take 45, and the ones on 60 now take 75, your working capital requirement has grown without your revenue changing. This drift is gradual and easy to miss unless you track the average.

Track days sales outstanding monthly. A rising trend over three months is a signal to act on collections before it compounds.

3. You are paying suppliers later to stay afloat

Stretching payables is a legitimate tool — up to a point. When it becomes the only way to make the month work, you are financing the business on your suppliers' balance sheets, and you will eventually pay for it in lost goodwill, lost discounts or lost priority when stock is scarce.

4. Payroll requires planning

Payroll should be the least interesting payment of the month. When you start timing receipts around it, or moving money between accounts to cover it, the buffer is gone. This is the point at which most owners finally act — and it is later than ideal.

5. You are declining work you could deliver

This is the most expensive symptom because it is invisible in your accounts. Turning down a large order because you cannot fund the delivery does not show up as a loss; it shows up as growth that never happened. If you are saying no to viable work for cash reasons, the constraint is capital, not demand.

6. Stock is not moving

Inventory is cash in another form. Stock that has not sold in six months is working capital you have already spent, sitting on a shelf and often losing value. Reviewing slow movers quarterly and clearing them — even at reduced margin — converts dead capital back into usable cash.

7. One customer dominates your revenue

Concentration is a cash flow risk as much as a commercial one. If a single client is 40% of turnover, their payment behaviour effectively sets your cash cycle, and their loss would be existential. Diversifying takes time, which is exactly why it should start before you need it.

What to do once you have spotted it

1. Build the 13-week forecast. You cannot manage what you have not mapped.
2. Chase receivables systematically rather than reactively — a simple reminder schedule recovers more than most owners expect.
3. Clear slow inventory and convert it back to cash.
4. Line up a facility before you are desperate. Lenders assess a business in control very differently from one in crisis.
