How does the duplicate detection work?
To prevent fraud, Klippa uses automatic detection of duplicate invoices. We use a few techniques to mark a transaction as a possible duplicate:
- We look at the document, whether we have seen the exact same document results before in our system
- We look at the combination of certain fields
Invoices
We mark as duplicate if 2 out of 2 fields are the same:
- Invoice number + merchant
- Invoice number + amount
Expenses
We mark as duplicate if 3 out of 4 fields are the same:
- Merchant
- Invoice number
- Amount
- Date
Example of possible duplicate transactions
- Notification 'possible duplicate of X on date Y' when opening the invoice.
- Notification 'possible duplicate of X on date Y' in the overview of all invoices.
