I will buy CS-Cart Multi-Vendor and built a marketplace.

 

May I know what license type for the marketplace where each vendor/store owner have their own

Live Help on their own product pages? Basically each vendor only allow to receive visitor's chat on

their product page and other vendor can't see it. Can I set it like vendor = department?

 

Do I need VPS or dedicated server to run it or just any standard shared host which don't have root access? 

Have you keep update the software?
