QuickBooks Online Sync Error: Another customer, vendor, employee, or donor is already using this name in QBO. Please use a different name or ensure that there are no duplicates in Bill.com
Why the Sync Error occurs
This error occurs when a contact (customer, vendor, or employee) is trying to sync to Quickbooks Online (QBO) from PayMaker, but a contact of the same name already exists in QBO. All contacts must have unique names in QBO, regardless of contact type.
How to Fix the Sync Error
Edit the name of the customer, vendor, or employee in PayMaker so it is different than the existing contacts in QBO, and sync.
Note: We pay vendors using the Pay To field, so you can edit the vendor name field and it will not impact the payments.
