Hey Steve,
Welcome to the Pre-Sales Question channel and thank you for reaching out. We can’t necessarily guarantee whether the plugins will integrate properly, but from what I’m gathering from other threads relative your question, it looks like the WooCommerce Square extension should work properly with Event Tickets Plus.
I’ll go ahead and paste the relative threads below for you to review yourself. We offer a 30-day money back guarantee, so if things don’t end up working out we’d be happy to refund your purchase. I’ll also go ahead and link to our list of customizers just so you have that option in the case you need to hire a dev for assistance.
I hope this answer helps address your question and please let me know if you have any additional questions or comments. Thanks again and have a great evening. Cheers!
