Hello - been searching for an answer on this question but did not find any. 

I am trying to set up Commerce so that a guest can buy an item without actually being a member. I just like them to fill out their name, adress, email and maybe phonenumber and then they would be sendt an invoice directly and an email for payment info of that payment of some sort. 

Is that possible?

As mentioned above, that is not something possible at present. 

I have mod for that. Account being created at the checkout. Card details will be saved also.
