Hi there Matt,
Thanks for getting in touch with us and for your interest Events Calendar PRO 🙂
Is the $89 Events Calendar Pro fee annual or one time?
It’s an annual fee (you get a discount when you renew) that gets you access to updates and premium support. If the license expires and you decide not to renew then the plugin will continue to work, but you won’t be able to access further updates (bug fixes and new features) nor have access to premium support.
Please let me know if there’s anything else I can do for you,
Best,
Nico
