Profit is not money in the account

Businesses with good margins run out of money regularly, and they do it in a sequence that is boringly predictable once you have seen it. The problem is never the margin. It is the order in which money arrives and leaves.

Profit is an opinion about a period. Cash is a fact about a day. A statement can show a healthy year while the account is empty on the fourteenth of the month, and it is the fourteenth that decides whether you are still trading.

The sequence

It usually goes like this. Work is won, which is good. Delivering it requires spending first: materials, subcontractors, an extra pair of hands, your own time not spent selling. The money comes in afterwards, on terms someone else set. Meanwhile the next job is won, which requires spending first, and so on. Growth makes this worse rather than better, because each new job enlarges the gap between spending and receiving.

This is why a fast-growing operation can be in more danger than a flat one. The flat one has a stable gap. The growing one is widening it every month and calling that success.

“You do not fail because the work was unprofitable. You fail on a Tuesday, because of a date.”

Watch the gap, not the total

The number worth tracking is not revenue and not profit. It is how many weeks of committed spending you could meet if no new money arrived. Track it weekly, on one line, and watch its direction rather than its level. A number that is falling steadily while revenue rises is the specific signal this note is about.

Three levers, in order of cheapness

Change the terms. Deposits, staged payments, shorter terms on new agreements. This is the cheapest lever and the least used, because asking feels awkward and cutting costs feels virtuous.

Change the timing of your own outflows. Pay for things closer to when they earn. This is genuine and limited; it does not create money, it moves it.

Reduce commitment. Fewer fixed obligations means a wider tolerance for late payment. Fixed costs are not just expensive, they are inflexible, and inflexibility is what actually kills.

A worked example

Take a business that turns over a comfortable amount with a decent margin, invoicing on thirty days and being paid on fifty. It commits to a piece of work requiring an upfront payment to a supplier. The work is profitable. The supplier is paid in week one, the client pays in week eleven.

For ten weeks the business is lending money it does not have to a client who is not aware of it. Two such jobs at once, plus one client paying late, and a profitable business cannot meet payroll. Nothing about that story involves bad work or bad pricing.

What to do this week

Write down every payment you are committed to over the next eight weeks, with dates, and every payment you expect, with the date you actually expect it rather than the date on the invoice. If the second list is optimistic, you have just found the thing to fix first.
