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
- Accounts Payable configuration access
The Sage Intacct way
Where to find it: Accounts Payable > Setup > Configuration > If bills, checks or adjustments are assigned duplicate numbers
- In Configure Accounts Payable find If bills, checks or adjustments are assigned duplicate numbers.
- Choose Show warning, Do not allow transactions to be created, or Do nothing.
- With Do not allow, a bill with the same number for the same vendor cannot be submitted or posted.
- With AP Automation, incoming drafts that match an earlier bill are flagged Duplicate and you can view the original.
Limits in Sage Intacct
- The check is per vendor only. The same bill number from two vendors is not caught.
- AP Automation only compares against bills previously submitted through AP Automation.
- The check does not look at amount or date.
The Pulsify way
- Forward the supplier's invoice to Pulsify.
- Pulsify compares the invoice number with punctuation and case ignored, plus the same vendor, invoice date or tax ID.
- It checks other Pulsify documents and active bills in Sage Intacct.
- A possible duplicate is flagged. Open the match, then reject or approve anyway.

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 the duplicate setting on Do nothing.
- Relying on the check when the bill number is typed differently, since it works on the number.
