Good afternoon Laura and welcome to the Events Calendar forum!
Thank you for your interest in our products.
We’ll be glad to answer your question.
The short answer is yes. You can customize the ticket design (and pretty much any view we have).
You might want to read our Themer’s guide to get a sense of how that works.
If coding is not really your thing, you can hire one of our recommended customizers to do the customization for you.
Let me know if that helps.
Have a great day!
Geoff B.
