WooCommerce Default Customer lets you select a Customer to assign automatically to new orders. This may be helpful if you don't add new customers automatically.

You might create a Customer you call WooCommerce Orders for this purpose.

Within an Order you can import all contact information, so it is possible to use one Customer card for all WooCommerce orders. Or, use it to catch errors where a customer is not found and manually correct any Orders set to the Default Customer.
