This is not a feature request, but it’s already a solved need (I hope I’m writing in the right section).
I’ve developed a new plugin for WooCommerce: When a new order is made on WooCommerce, it will generate a new invoice on InvoicePlane.
Also the customer information are sent to InvoicePlane: If all user information match, it will get that customer, otherwise a new customer will be created and linked to the invoice.
I really hope it would be a very good feature for you.
