Multiple customer locations

aceX

One of my clients is a distribution company. Some of the customers he is working with have multiple locations and he would like to budget and track the sales per customer location. Also for each location they appoint salesperson with specific target. Furthermore, the sales territory is divided into sales areas and he would also like to track the sales per area. Obviously, some of the customers might have locations in different areas.

Any suggestion how to resolve this using NAV standard features or limited customization.
