Which CMS to choose for the trading platform?

Question

CMS

There is a task to develop a trading platform where _any_ user will be able to:
- add products ("buy now" + auctions) to the general website catalog and manage sales
- add companies (company catalog)
- add events
Example: onlinedemo.sitemile.com/?theme =auction
but this is Wordpress, it's unlikely that it will be able to withstand such a load when users appear.
What other CMS (possibly not Russian) are suitable for this purpose?
Maybe there are ready-made solutions for Bitrix?

Answer 1

OpenCart is quite suitable for these tasks.
The Bitrix online store, as far as I remember, already has such functionality.

Answer 2

GeoCore MAX what you need, contact me

Answer 3

I personally use LiveStreet CMS and am completely satisfied. Everything is just cheap and extremely easy. I've been using it for a long time and I'm happy with everything.
