When you buy IDEAL Dispatch , you get access to our technical help service (support@pointdev.com) and this gives you free updates for a year.
Once this period has ended, if you want to update your version or continue accessing our technical support, you must renew your software maintenance. The fee for this is 30% of the cost of the number of licenses you hold.
It's all explained here: http://www.pointdev.com/en/ideal-dispatch/price.php

To check out the expiration date of your current license, please select the menu ? then Registration software from the main menu. The date that counts is the one that appears in the area entitled Software registered on.
