Hello Finley Design,
This would likely be possible with some customization. Our WooCommerce Tickets add-on does keep track of how many total tickets are available and sold, and therefore a quick calculation would get you how many are left. But it doesn’t display that out of the box. It does display a “sold out” indicator on the event page though.
While we can’t assist with customization, we do have some resources available that can help. We have our Themer’s Guide (https://theeventscalendar.com/support/documentation/events-calendar-themers-guide/) and documentation (http://docs.tri.be/) available if you’d like to take a look at those and see if they provide the information your looking for.
If you have any other questions, please ask!
