Great question, Taylor!
Event Tickets Plus does not have that functionality, I’m afraid. We actually rely on the e-commerce plugin that powers the transactions (e.g. WooCommerce) to handle all the checkout process. So, if the ecommerce plugin you are using has that built in or has an extension that accepts payment plans, then it is very likely that it will work nicely with our plugin.
Here’s an extension for WooCommerce that allows you to accept deposits. I haven’t used it myself, but might be worth looking into!
Does this help answer your question? Please let me know. 🙂
Cheers,
Geoff
