We just purchased MapPoint so that we could plot multiple routes from one zip code to another; however, when we try to import data from excel it will only let us use one zip code.
We do not need this software for driving directions, we need it to map out the territories of our transportation carriers. Do we have the right software? Are our goals achievable with MapPoint?

MapPoint ist the right software.
But you have to use an addIn "IC-DistanceAnalysis (http://www.profit100.eu/download/ic-business-tools.html)".

Have a look to our partners logistic-website (http://www.lucassen-consulting.com/geomarketing).
If you register (http://www.profit100.eu/register.html), you will get a 3 month license for free.

Kind regards
