Monthly Subscription & future latest versions

swiftit

Its a dream come true when you buy teamviewer full version and support your customers with a peace of mind but it just happened that out of my excitement I did not paid attention and charged for the whole year despite of offer showing per month amount. Its fine with us but I was just wondering if there is a way in future to get the amount deducted monthly instead of whole year together , also if the future version upgrades are part of the subscription.
