Hi Deanna,
Thanks for your interest in our products. ?
With the free version of Event Tickets, PayPal is about the only option for accepting payments. With Event Tickets Plus, you have the ability to use WooCommerce which opens up tons of gateways like Stripe, Square and Autorize.net (there’s many others supported through them as well). So in short, we don’t process the transactions.
If all your events will be on the same site, you should be fine with the personal license. With a large amount of items in the database, it’s important to have a good web host though 🙂
We do have a non-profit partnership program that you can apply for here → https://theeventscalendar.com/apply-for-npp/
Hope that helps you out!
Take care,
Ed ✌️
