USER STORY - SITE OWNER: Review Billing Address / Invoice Creation

[DietkeSt]

I wish to have the option to access billing information through user sign-ups for my bookkeeping and invoice creation.

• [x] Add address option
• [ ] Add invoice option
• [x] View orders connected to customer

Address option added and orders are also accessible and manageable.

Adding invoice option as a Feature Request for now.
