[ILUG] accounting software

[Bill Appelbe]

Hi
I know somebody that is trying to replace the computer system in his small
business, he has asked me about Linux.
The main question I have is what accounting software is out there, in particular
he needs a sales ledger, for Linux?

GnuCash describes itself as a personal finance manager, as do all the 
applications that I have found.

Has anyone used Linux software for accounting in a small (or not so small)
business?
