Hi,

We are a b2b Software company.
We have a structure where your customers can create an offer, edit it, approve it and turn it into an order.
In addition, every customer who logs into the system sees the products he needs to see at the prices and discounts he should see.
Please contact for detailed information.

This is nice, Did you also found a solution when the logged in User (portal) has a special invoice address set on the contact form and how can we use the  shipping methode set on the contact form??

You can only selcect the delivery address and add a new delivery address. But invoice adres is the same as the adress from the signed in user
