"Yet another" Enrolment on payment plugin offers you the ability to create paid courses, with the addition of a notification function about the expiration of the training period and re-payment.

This plugin contains the following features on top of the core payment plugin:

• Payment is possible after the enrol period has expired
• Notifications can be triggered about the expiration of the training period and re-payment
• Extended enrolment duration, calendar month and calendar year
• Can show enrolment duration on page
• Free trial enrolment period
• Renew enrolment duration by paying again using the link in the navigation menu when it's about to expire
• Payment for missed unpaid time
• Manual user enrolment
  
• Uses group enrolment keys

By enabling the appropriate settings, you can limit the time of paid registration of students in the course. After the set time, access to the course is blocked and can be resumed by re-payment.

You can enable sending notifications about the upcoming student disconnection from the course. The frequency of sending is once a day.

This plugin is versatile, but it was originally designed to support my payment plugins to allow for recurring payments:

• Robokassa
• YooKassa
• bePaid
