How to change the Billing cycle of the Subscription?

NOTE: Currently, the Billing Cycle cannot be changed for Microsoft license-based subscriptions with active Add-Ons. Such tasks should be performed by the partner on behalf of the customer directly in the MS Partner Center.

1. Click on the Subscriptions tab, the section will be opened in a new window. Here you can see the subscription's existing billing cycle.  To change the billing cycle of the subscription:

Select the "Billing cycle".
a. Adjust the charge period (Monthly or Yearly).
b. Select "Save changes".

After saving changes, a pop-up window with a Terms & Conditions will appear, press the                           "I agree" button to continue.
