Linux Cash Registers?
evil_one asks: "I've been looking for cash register software for Linux, but I can't find any. I think that Linux would be the ideal platform for a bunch of smart terminals accessing a central inventory database. Has anyone implemented a similar setup? What are the advantages/disadvantages over a proprietary POS setup, networked or not?"
It's not very obvious from their feature-oriented web site, but Apropos uses Linux. See how LinuxPOS or Simple Simon meet your needs.
