CubeCart also keeps good records of your inventory and has an easy to use menu interface.
What's the catch? Does it cost anything?
It costs nothing to download and use CubeCart on an unlimited number of computer systems but you cannot remove the original Software's proprietary notices.
Don't worry. They have not got their logo plastered all over the place. They have just a couple of text links pointing back to their site. If you have a need to remove these notices, you can register a copy of the software for a small fee.
