Hi Alvaro,
Thanks so much for reaching out and for your interest in our products!
With Community Events, you can have users (or vendors) create events from the front-end of the site. Those events can be published into a particular category, which is how you can accomplish creating a separate calendar for each vendor, without giving them access to the back-end.
Community Tickets would allow your users to additionally create and sell tickets for their events that are created with the Community Events submission form.
Our products tend to integrate well with WooCommerce products, however we cannot guarantee compatibility. We have a great 30-day full refund policy, so if things really don’t work out the way you’d hoped, you can get a full refund.
Let me know if you have any other questions!
Thanks,
Jaime
