Sebastian de GoeijShort answer
Duplicate invoices mostly arise when the same invoice arrives through several channels, or when a supplier sends a reminder or copy. Prevent double booking and double payment with an automatic check on supplier, invoice number, date and amount, and by flagging unusual IBANs. Autoboeker flags duplicate invoices and duplicate contacts before booking.
Key takeaways
- Most duplicates come from multiple delivery channels.
- Reminders and copies often look like a new invoice.
- Check the combination of supplier, number, date and amount.
- A changed IBAN for a known supplier always deserves attention.
How do duplicate invoices arise?
The same invoice by email and upload, reminders with the original attached, copies with the same number, or one supplier set up as two contacts.
How do you detect duplicates automatically?
Combine supplier, invoice number, date and amount; a match on several points goes to review. Autoboeker flags duplicate invoices and contacts and checks IBANs.
