Hello there, eric51.
I can help you identify what's causing the duplicate transactions.
The transaction may not be duplicates but they might be vendor credits synced in QuickBooks. Both the bill and the vendor credit will sync over to QuickBooks Online (QBO) but the credit won't be applied to the bill in QuickBooks Online. If a vendor credit application only partially pays a bill, after syncing, the bill will still be unpaid and the vendor credit will be in fully unapplied status in QBO.
On the other hand, if the payment is applied to the remainder of the bill in Bill.com, when the payment syncs to QuickBooks Online, the application of the credit will then sync, and then the bill will be in paid status. For the vendor credit, it will be in applied status and associated with the bill.
We can also try running the reports again to see if the duplicates were manually created so you can delete them if necessary.
Feel free to use these links to help you manage your vendor transactions:
Please leave a comment below if you need anything else. We'll respond as soon as we can. Have a great day!
