All versions of the license – Single, Pro or Agency – contain the same features. There are no additional features in certain licenses.
The only difference is how many sites you can use the plugin on: Single allows you to use the plugin on one site; Pro allows you to use the plugin on up to 5 sites; Agency allows you to use the plugin on up to 25 sites.
If you buy a Yearly license, you are buying a subscription product that will renew every 12 months. You can cancel at any time. If you buy a Lifetime license, this is a single one-time payment with no renewals.
You can try out a Single license first then upgrade to Pro or Agency at any time. Here’s how to upgrade your licence. If you upgrade within 12 months of purchase, you’ll only pay the difference between the two licenses.
