Profit and cash answer different questions, and confusing them is the most common reason a good month feels bad.

Profit counts the sale when you raise the invoice. Cash counts it when the money lands. If your customers pay on thirty days and some of them drift to fifty, a strong sales month shows as profit now and cash in two months. Meanwhile the wages, the subcontractors and the stock behind that work were paid weeks ago.

Then there are the payments that never appear in profit at all. VAT collected on behalf of HMRC sits in your account and looks like yours until the quarter ends. Corporation tax builds quietly. Loan capital repayments reduce cash and not profit. A van bought outright takes the money now and spreads the cost over years.

Put those together and you can post a healthy profit while the bank balance falls every week. Nothing has gone wrong. You are simply reading a measure that was never designed to tell you what you can spend.

The useful question is not whether you made money last month. It is how much of that money you now hold, and how much is still sitting with somebody else.

If cash feels tight and you want one place to look first, look at the aged debtor report.

Not the total. The total is comforting and useless. Look at the report broken down by age and by customer, and read it line by line. Three things come out of that, every time.

• Which invoices are genuinely late, as opposed to simply unpaid because the terms haven’t run yet.
• Which customers are consistently slow, and whether you have quietly funded them for a year.
• Which lines are in dispute, or were never queried but were also never approved.

The last one is where the surprises live. Invoices sit unpaid because nobody chased, because the purchase order number was wrong, or because the invoice was never raised. During a first bookkeeping clean-up at one owner-managed trading business, we reconciled the sales ledger against delivery records and found twenty thousand pounds of goods supplied and never invoiced. The customer wasn’t refusing to pay. They had never been asked.

That is not unusual. It is what happens when invoicing lives in someone’s head instead of in the month-end routine.

Cash pressure feels worse when it has no shape. A rolling thirteen-week view gives it one.

The point isn’t forecasting accuracy to the pound. It’s knowing which week is the tight week. Payroll, the VAT quarter, the corporation tax date, the insurance renewal and the quarterly rent rarely land evenly. When you lay them out against expected receipts, the pinch points stop being a feeling and become two or three specific dates.

Once you can see those dates, ordinary decisions become available again. You can ask a customer to pay a week earlier rather than asking the bank for an overdraft. You can move a supplier payment by ten days with a phone call instead of missing it. You can decide whether the new hire starts in November or February, and know the difference that makes.

The British Business Bank’s Small Business Finance Markets reporting notes that around half of smaller businesses seek external finance, with more use of flexible products to support cash flow. Some of that is genuine growth funding. Some of it is borrowing to cover a gap that a better debtor routine would have closed for nothing.

The second question, once the timing is mapped, is harder and more valuable. Where is the cash being consumed?

Most owner-managed businesses carry at least one line of work that looks busy and contributes very little. It might be a client who takes three times the management time for the same fee. It might be a service you kept because a good customer asked for it four years ago. On a total profit figure it disappears. Split the numbers by job, client or service line and it becomes obvious.

This is where management information earns its keep. A monthly report that shows cash, debtors, creditors and performance by the part of the business that generated them gives you something to act on. You can reprice. You can change terms for the slow payers. You can stop taking a type of work.

None of that is possible from a set of year-end accounts filed nine months after the period closed. By then the decision has already been made for you by whatever cash was left.

All of this rests on the bookkeeping, which is the part the profession tends to treat as admin.

An aged debtor report is only as honest as the last reconciliation. If receipts have been posted against the wrong invoices, or credit notes were never issued, the report will show debt that doesn’t exist and hide debt that does. A cash view built on that is worse than no view, because you will trust it.

So the order matters. Complete bookkeeping first. Banks reconciled. Supplier and customer balances that make sense and can be explained. Then the reporting on top, delivered on the same date every month so you can plan around it.

That is what our first ninety days are for. Month one puts the foundations right and identifies the historic gaps. Month two builds the routines, including credit control. By month three the finance function runs to an agreed timetable, and reports arrive on the agreed date each month, provided the information is with us.

Once that is running, cash stops being a monthly surprise and becomes a number you already know.
