Revenue leakage: the money you earned but never billed
Work delivered but never invoiced, and prices that were agreed but never applied. Where revenue leaks, and how to find it.
Revenue leakage is money a business has earned but never collected – not because a customer refused to pay, but because nobody ever asked them to.
Where revenue leaks
The causes are usually ordinary:
- Delivered but never invoiced. The work was done, the order was fulfilled, and the invoice simply never went out.
- Prices not applied as agreed. A rate rise that never reached the billing system, or a discount that ran past its end date.
- Recurring charges that stopped. A schedule was changed and a line quietly disappeared.
Each one is small on its own. Together they add up – and they rarely show in the profit and loss, because money that was never billed never appears anywhere.
How to find it
The reliable method is to compare what was delivered with what was invoiced, line by line, after netting any credit notes. Every gap becomes a case: an amount, an owner and a history, worked until it is either recovered or explained.
Found, approved, invoiced and collected are four different numbers. Keep them apart.
It also pays to ask why each gap happened. Fixing the cause – a missing billing rule, a schedule that was not updated – stops the same leak next month.
