Hi @subrisi,
Thanks for reaching out to us. I’m glad to hear that you enjoy our plugin!
Please note that WC Vendors lets you give commissions to vendors for every product sold by themselves. For example, if the product is sold for $100 with a 90% commission to vendors, they get $90, and you get $10.
It’s different from the affiliate system, where the commission is given to people who refer your products to customers through affiliate links.
If you wish to restrict which product categories can be used, I’d recommend creating and managing your vendors’ products. You can also prevent them from creating and editing their own by disabling “Submit Products” and “Edit Live Products” at WP Dashboard > WC Vendors > Settings > Capabilities > General.
I’m afraid we don’t have a feature to restrict which customers can buy the products. I’ll raise this as a feature request to our development team to review.
Hope this helps!
