The eMapshop’s big advantage is that it is a perpetual license and you own it. Therefore you don’t have to pay year after year for the privilege of using it. But we all know the political world changes. What happens when you decide it is time to update your maps? It’s really very simple. You just buy a new package at the prevailing price and we give you a credit for your old package less $99. This way you can update it as frequently or as infrequently as you like for a minimal charge. If our software is improved and /or your operating systems change, it is all upgraded at the same time: all for one low fee. And with every upgrade you get a year of free maintenance and support just like you did when you first bought the package.
