Hi there!

Your subscription will be a one-time payment. You will not need to renew later to keep using end-products. But if you need update and support after the expiration then you need to renew the subscription.

You may consider the Developer plan which has a subscription for 1 year and unlimited website lisences! And this will give you access to all of our products. Literally, no bound at all! It includes Templates, extensions, sp booking component, and sp page builder pro...all!

Best Regards
