Are you seeing this error when syncing orders into QuickBooks Desktop?

Error

Error: 3100.

" Error:The name "John Smith" of the list element is already in use."

This error usually occurs when a customer already exists in QuickBooks, but is not mapped to the WooCommerce customer in MyWorks Sync > Map > Customers.

Troubleshooting Steps

Visit MyWorks Sync > Map > Customers and ensure that the related WooCommerce customer is mapped to the appropriate QuickBooks customer.
If the two customers shouldn't/don't need to be mapped, slightly change the name of the customer in QuickBooks so they don't conflict.
