Why a profitable brand can still run out of cash

It is one of the most common conversations we have. A founder shows us a profit and loss account with a healthy number at the bottom, then tells us they are worried about paying next month's supplier invoice. Both things are true at once, and it is not an accounting error.

Profit and cash are different questions. Profit asks whether you sold things for more than they cost. Cash asks whether the money is in your account today. For a business that buys stock, those two answers can be months apart.

Where the money actually goes

Follow a single order from the moment you commit to it. The pattern is always the same, and the shape of it is the whole problem.

The cash gap

One order, start to finish. Note how far apart the first payment out and the first payment in actually are.

  1. Deposit to supplierCash out

    Often before production even starts

  2. Balance paidCash out

    Due before the goods ship

  3. At seaWaiting

    Nothing happens, but the money has gone

  4. Customs and dutyCash out

    Payable on arrival, before a single sale

  5. Sitting in the warehouseWaiting

    Now costing you storage as well

  6. Selling periodWaiting

    The only stage that was ever in the plan

  7. Payment settlesCash in

    Your provider holds it a while longer

  8. Returns window closesCash out

    Some of it goes straight back out

For most brands this is months rather than weeks, and it runs alongside your existing UK stock cycle rather than instead of it. That is the bit that catches people out: you are funding two businesses at once.

Growing faster makes it worse, not better

This is the part that catches people out, because it is the opposite of what instinct says. When sales are climbing, the obvious response is to order more stock. Quite right too, running out is its own disaster.

But each order is bigger than the last, and you pay for it before you have collected the money from the previous one. Growth does not fund itself. It consumes cash, and the faster you grow the more it consumes. A brand growing at thirty per cent has a harder cash position than the same brand standing still, even though it is a far better business.

Illustrative, not a client figure: say stock costs you sixty pence in every pound of sales. Sell an extra ten thousand pounds next month and you need six thousand pounds of stock to do it, paid for well in advance. Do that three months running and you have funded eighteen thousand pounds of growth out of a bank account that has not yet received any of it.

The other things quietly taking the cash

  • VAT, which arrives in quarterly lumps and is never really yours
  • Corporation tax, sitting nine months out and easy to forget
  • Returns, where the refund goes out long after the sale went in
  • Payment providers holding your money for a settlement period
  • Slow movers, which are last season's cash still sat on a shelf

None of these show up as a problem in your profit and loss account. All of them show up in your bank balance.

What actually fixes it

Not working harder, and not selling more. Three things, in order of how quickly they help.

First, a rolling thirteen week cash forecast. Not a budget, a week by week view of what is coming in and going out. It turns a vague worry into a specific date, and a specific date is something you can act on weeks ahead rather than the morning it bites.

Second, supplier terms. Thirty days instead of payment up front changes your cash position without changing your profit by a penny. It is often the single highest-value conversation a founder has all year, and most have never asked.

Third, honesty about slow movers. Stock that is not selling is cash you already spent, sitting there pretending to be an asset. Clearing it at a discount feels like admitting a mistake. It is usually cheaper than the alternative.

If this sounds familiar

Profitable on paper and tight on cash is a solvable problem, and it is nearly always a timing problem rather than a trading one. If you are expanding into a new market, the same maths applies twice over, which we have written about in what US expansion actually costs a UK e-commerce brand.

Either way, the first step is seeing the next thirteen weeks clearly. That is usually where we start.
