Hi Mike,
Thanks for posting. I’m not specifically familiar with WooCommerce Product Vendors. Our WooCommerce Tickets plugin shouldn’t interfere with another WooCommerce product, but we can’t always guarantee that it will integrate smoothly. I’m going to get in touch with the folks at Woo and see if I can get a copy and run some tests.
To verify, are your product vendors going to be submitting events from the frontend of the site? Or are they just making tickets from the backend, with a user account? WooCommerce Tickets isn’t really designed to work from the frontend, so I’d be hesitant about suggesting that.
Best,
Leah
