The price is certainly right, $99 for five users. And it runs on Linux, Mac OS X, and Windows.

Frankly, I think Appgen's web site could be laid out much better. But it looks like you can customize it using either the ODBC interface or the [link|http://www.appgen.com/products/developers.html|Linux Business Application Generator], which is either $99 or $599.

Andrew should be able to tell you more. He's also mentioned at least one other Linux accounting package in the past.

Good luck,

Tony
