Hello @Namiko,
Welcome, i look a little the b2B aspect and ClicShopping has different capacities in this field
- the catalog without the price ==> Yes you can for all products or just a specific products
- with a specific account for this people. => Yes you have 2 forms, one for the customer one, for B2B. You can remove the B2B.
Look the B2B configuration, customer group and the option inside the products, you will see the different settings.
