Is the PHP Coin ticket system good? It is free and I like it, but are there much better ones out there for free or very little?

Do you have a link?

PHPCoin is more than just a ticket system. It is an order, invoice and billing system as well. Plus, it can be set up to be your entire site which can offer a simple one-stop solution for those who are interested in that.

I have not tested the latest versions but the last time I looked it was the best free script available in my opinion.

I have seen many threads on this topic. Try searching for phpCoin. You should find dozens of posts regarding the software application.
