A supplier bill looks like one you have already paid
Same amount, same reference, eleven days apart.
€18,400
1 bill
- What G1 noticed
- A bill for €18,400 matches the amount and reference of one posted on the 6th. Both are approved, one is already in a payment run. The supplier has never invoiced the same reference twice in three years of history.
- Why it matters
- €18,400 leaves the bank on Friday unless somebody stops it. Recovering an overpayment takes weeks. Stopping one takes a minute.
- The question for management
- “Is this a second invoice for the same work, or the same invoice twice?”
- Suggested next step
- Hold the payment run line and confirm with the supplier before release.
Reviewed by a finance analyst
Three years of this supplier's history were checked before it was raised. They have never reused a reference.
