Hello Ingo

Thank you for your purchase.

A license can be a yearly subscription-based license, or it can be a lifetime license.

A license plan is either Basic, Pro, or Developer. It's clearly stated on our pricing page that the Basic License plan does not include Packages of Services:

The prices of Pro and Developer licenses haven't changed when we added the Packages feature. As per our Terms & Conditions:

• Please note that it is at our discretion to decide which Price Plan includes which feature, as well as which feature will be included in the upgrade.
• By purchasing one of the plans offered on our Website, you enter into a legally binding contract with TMS and you agree to these Terms of Use.

In short - just like a vast majority of WordPress plugins, we too separated the license plans to exclude certain features for cheaper plans. As we're developing more advanced features, in the future the list will expand (for example, we plan to release White-Label only for the Developer license. Also, the Membership feature will be developed and included either in Pro and Developer plans, or only in the Developer plan - our management still hasn't made the decision on this yet, so I can't say for sure).

You can read more about the Packages on our documentation, but they are not a replacement for the Membership feature. When you add a service (or multiple services) to a Package of Services, you allow your customers to book a fixed amount of appointments per service. So, if the package contains 3 services, you can define the # of appointments for each service (say, Service 1 provides 3 appointments, Service 2 provides 2 appointments, and Service 3 provides 10 appointments).

Please let us know if you have any further questions.
