QuickBooks Online Sync Error: Cannot delete Customer: This customer cannot be deleted because there are unbilled charges for this customer
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 is linked to active/unbilled charges in QBO.
How to Fix the Sync Error
There are three options to resolve this issue:
- Reactivate the customer in Bill.com until the charges are completed in QBO
- Delete the unbilled charges in QBO and sync again for the customer deletion to sync to QBO
- Contact Customer Support to clear the error if the deletion should not be synced to QBO
