QuickBooks Online Sync Error: Bill null: XXX cannot be created in Bill.com - Found multiple objects by search without integrationId: XXXXXX, XXXXXX

Why the Sync Error occurs

This error occurs when a bill is attempting to sync to PayMaker from QuickBooks Online (QBO), but there are one or more bills with the same invoice number for the vendor in PayMaker.

How to Fix the Sync Error

Compare the bills in PayMaker to the bills in QBO and make sure they all have unique invoice numbers. Edit the invoices numbers as needed and sync.

If you do not see any duplicate invoice numbers, please contact Customer Support.
