Hey there Ross, thanks for getting in touch!
Great question. Canvas and Uno are both developed by WooThemes, so those should play nicely together and with WooCommerce as well. Score!
WooTickets builds right on top of WooCommerce by allowing you to create, add and manage tickets directly from an event editing screen. Those tickets get added as Products in WooCommerce in their own Tickets category. Another score!
Stripe is a very developer-friendly payment gateway, and I see WooCommerce offers a simple integration for it as well. That sounds very promising.
I can’t speak directly for the themes or for Stripe, but what you’re describing sounds like a solid lineup. What I can speak for is that WooTickets will integrate nicely with WooCommerce for ticket creation and management. I think you’ll love it. 🙂
Does this help answer your question? Please let me know.
Cheers!
Geoff
