When you renew early, we add the remaining time from your current license to your renewed subscription term. You don't have to wait until your term expires just to get your money's worth. You may also allow your existing subscription to auto-renew seamlessly for another term, this way, you do not need to place an additional order.
To renew manually, please visit https://www.dbvis.com/buy/ and click the renew button for the applicable DbVisualizer Pro subscription you want to renew.
