Duplicate payment is when the same supplier invoice is entered or paid more than once. It often happens when an invoice arrives by two routes.
Before you start
- Sage X3 Financials and Purchasing
- Function and site rights for the screen
The Sage X3 way
Where to find it: Financials > Invoices > Purchase invoices
- On a purchase invoice, enter the supplier invoice number in the Supplier doc no. field (BPRVCR).
- X3 checks that the same number is not entered twice for the same invoicing supplier.
Limits in Sage X3
- The check is documented on Purchasing invoices. The supplier BP invoice help page does not describe it.
- A duplicate Source document can also give a warning in some versions. Test it in yours.
The Pulsify way
- Forward the supplier's invoice to Pulsify.
- Pulsify compares the invoice number with punctuation and case ignored, plus the same supplier, invoice date or tax ID.
- It checks other Pulsify documents and active bills in Sage X3.
- A possible duplicate is flagged. Open the match, then reject or approve anyway.
Pulsify connects to Sage X3. We set up the connection for you.
What Pulsify does not do here
- Pulsify flags. You decide.
- A duplicate with a quite different invoice number may not be found.
Common mistakes
- Leaving Supplier doc no. blank, so the check has nothing to test.
- Entering direct invoices through Supplier invoices and assuming the same check applies.
