A number of independent software vendors have developed fleet management solutions on top of MapPoint, mostly aimed at smaller fleet operators or more cost-conscious clients. A sponsor of this site, Locarta (<a href="http://ads.directionsmag.com/ads_v1/click.php?bannerID=57">www.locarta.com<a>) is a prime example of such a vendor with a very strong but affordable solution.
