4,500 correction entries at one organisation: what correction entries say about your P2P process

In a recent audit we reviewed more than 2 billion euros of spend. The expectation beforehand: at that volume you always find a series of duplicate payments. The outcome was different. Exactly one undisputed duplicate payment was found, of 258 euros. An excellent score for this organisation's payment controls. And yet the audit was anything but empty: the data showed a structural pattern of around 4,500 correction entries.

What exactly is a correction entry?

Every correction entry is the scar of something that went wrong earlier. An invoice booked to the wrong cost centre, the wrong vendor, an incorrect VAT code, a matching difference that was forced through manually. The error has been fixed, so on the surface nothing is wrong. But the fix itself took time and, more importantly, the pattern shows where the process structurally chafes.

Why correction entries are the better risk gauge

• They are a predictor: where a lot is corrected, one day something will not be corrected. Then the error becomes a loss.
• They are measurable and objective: the number of corrections per supplier or per booking type can be pulled straight from the system.
• They point to the root cause: in our case the 4,500 corrections were concentrated in a small number of suppliers and invoice flows. That makes targeted improvement possible.
• They quantify hidden costs: every correction costs processing time for the finance team and for the external auditor.

From pattern to improvement agenda

The follow-up analysis is always the same: group the corrections by supplier, by booking type and by cause. Usually a classic 80/20 picture emerges: a handful of suppliers or one invoice flow causes the majority. The solutions are rarely spectacular, think of agreements on invoice specifications with that one supplier, an adjusted matching tolerance or closing a duplicate input channel, but the effect is lasting.

The lesson for every CFO

An audit that recovers little money is not a failed audit. Recovery is half the story; the other half is knowing where the next loss will arise and preventing it. So with every recovery audit, ask not only about the claims found but also about the process report. With us it is a standard part of every engagement, even when there is little to recover.
