Different type of user and business

Hello,
I need that my ecommerce have two business categories:

one for final user:
(can buy single item with final price)

and one for business to business users:
can buy only 16x multiple quantity with special price.


I can simply create different categories for this different type of user, but
what I have to do to avoid that final user see special cateries and special price?

I need, that:
Final user see only single item caterories
Business user see only multiple unit with special price cateries.

What I also need to do to make different type of user?

thanks in advance
Giorgio

Hi,

You can restrict the menu via the Joomla options to a type of users, and you can restrict too the categories in HikaShop.
To set a usergroup at the registration, I think that there is third component which are doing that.

For this system, the users must be registered before anything.
