Duplicate Invoice
The Duplicate Invoice notice means Mod AI detected that this invoice may be a duplicate of another invoice already in the system. Catching duplicates before payment is one of the most important things Mod AI does for your AP team.
What Triggers It
This notice appears when Mod AI detects:
- A matching invoice number and vendor combination already exists in the system.
- Very similar amounts and dates from the same vendor, even if the invoice number differs slightly.
How to Resolve
- Open the notice to see the potential duplicate invoice.
- Review both invoices side by side -- compare the invoice number, vendor, date, amount, and line items.
- Choose one of the following options:
Option A: Mark as Duplicate
If the invoice is truly a duplicate, void or delete the duplicate copy. The original invoice remains in the system for processing.
Option B: Mark as Not Duplicate
If the invoices are legitimately separate (e.g., same vendor, similar amount, but different orders or billing periods), dismiss the notice. The system will remember your decision for this specific pair.
caution
Always review both invoices before dismissing a duplicate notice. Paying the same invoice twice is a common and costly AP error.
