If you mean market management there are many to choose from with varied prices.
The best suggestion you will hear is find a mapper you trust, and take the advise of him.
No matter how good a system is, if the mapper can not make the most of these features they are pointless.

Asking about management will only bring out people dedicated to one system or another and not an objective response of use to you.

I use cossie management if you interested
