Hi i would like to ask some question:

1. Can i block the shop for new customers ? I want it to be opened for existing customers only ? 

2. Can we customize the theme by ourselves (colors , logos ...) ?

3. Cause we sell to B2B business , we want to charge only 10% from the order , ex. if the cart subtotal is $1000 the customer will pay only $100 , can we custom things in the checkout ?
