Automatic user account creation add-on registers a profile for every guest making an order at store. To create an account, the add-on uses e-mail, specified by a client, and generates random password, which is shown after autoregistration.

With the add-on installed in the store, Vendors can create their own payment methods, Customers can place the order directly to vendors and the Administrator can get the vendor's commission paid via special orders.
