If you do not want your "Annual Billed Monthly" subscription to renew automatically for another year at the end of the 12th month, you need to uncheck the "Auto-Renew" box in the Order Management page of your Gobbler Marketplace account here: Gobbler Marketplace account login.
Then click the "Turn Off Auto renewal" button on the small pop up screen that comes up after you uncheck the "Auto-Renew" box.
Your "Annual Billed Monthly" subscription is now set up to stop on the last day of the 12th billing period.
The subscription will not stop at the end of any month, unless it is the 12th and final month of your annual plan.
