Hi, Katherine. Thanks for your interest in our plugin suite.
Our Community Tickets (CTix) add-on requires a PayPal account that has Split Payments enabled (https://theeventscalendar.com/knowledgebase/new-user-primer-community-tickets/), which is no longer supported by PayPal by default, so you’ll want to first figure out if you’re able to get that approved.
If you have that enabled, then the next step is figuring out if any conflicts exist with your theme and other plugins, such as WC Vendors (which we do not test with).
If you use Event Tickets Plus (ET+), each WooCommerce ticket is create as a hidden Product (doesn’t appear in your WooCommerce Shop).
Last but not least, we have Bundles and a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
I hope this info helps. Let me know if you have any follow-up questions.
