Why the Sync Error occurs
This error occurs when a customer is deleted in Bill.com and the deletion is attempting to sync to QuickBooks Online (QBO), but the Customer has an open/non-zero balance in QBO.
How to Fix the Sync Error
There are three options to resolve this issue:
- Reactivate the customer in Bill.com until the customer has a non-zero balance in QBO
- Delete the customer's invoice(s) in QBO and sync again so the customer deletion syncs to QBO
- If you do not want the deletion to sync to QBO, contact Customer Support to request to clear the error
