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 PayMaker 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 PayMaker 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
