I sold a Point of Sale software package that might work for you. It has no scheduling or shipping modules, but it will do order entry, purchase orders and receiving, including "landed cost" of your inventory. It's not fancy, but you can receive a PO to get your goods in stock quickly, then apply brokerage and shipping fees as you recive the bills. It will update your inventory costs by averaging the extra costs across the itmes in the PO.

Of course it will do your billing and print packing lists, etc.

I sold their software for about 10 years and can't tell you a negative thing about them. Good support, good product and great people.

Don't know if you're looking for much more, but it's a place to start. It's sold through dealers only. You can find out more at www.keystrokepos.com
