You can apply auto-renewal or manual renewal for your subscription.

When you order subscription, you can select the option of auto-renewal in the last step of ordering. If you forget to select this and would like to change to auto-renewal, you may login Avangate myaccount to find the order and change the renewal type.

For auto-renewal orders, Avangate (contracted with Easypano to manage our online sales) will charge the renewal amount automatically on the billing due date.

If you apply manual-renewal, you need to click the renewal link in your User Panel account to make the payment.
