Good evening Nathan and welcome back!
Thank you for reaching out to us.
I would love to help you with this topic.
Is it possible to set billing for the events to occur after the event? Or 24 hours before the event?
Since we do hand over all of the transactional aspect of things to the E-Commerce plugin of your choice, the short answer is yes.
But that will be done via your E-commerce plugin (e.g.: WooCommerce).
Either via some customization, or through the use of a plugin (e.g.: https://woocommerce.com/products/woocommerce-pre-orders/)
Full disclosure, we have not tested the above plugin, so there might be some customization necessary.
Let me know if that helps.
Have a great day!
Geoff B.
