Open Source Multi-Channel Order Management

Atrex is a pretty cool shareware program by a company that calls themselves Millennium Software. The best part about this program is that you can download it for free, load sample data provided by the author, and try the fully functioning program out.

I was actually pretty impressed with the extensiveness of the program. It has a lot of features that you would expect, and a few that you wouldn't from a shareware program. However, no realtime UPS/FedEx integration, limited card processing capaibilities, a cumbersum GUI, and limited support for e-commerce are going to make me pass on this platform. However, someone on a limited budget, with less requirements, may find this program very appealing.
