1.-3.) Thank you!

4.) o.k. What about a 3rd-Party addOn like WP-Invoice

Can it be used with your guest logic? Not sure if a manual creation of customer adress is a good solution in the long run. WP-Invoice also supports selection of registered users.

Is it possible to create a connection between your customer fields and WP-Invoice adress fields ?
