Nowdays commercial software have equivalents in Free software or GNU licencing. Free software very often is used for generating sales, talking about a ticket software, we are going to mention two popular scripts PHP Support Tickets and Troubleticketexpress.
TroubleTicket Express is a popular modular system, but it's free version is unable to support an DBMS, if you "want" Mysql Support,you have to pay $30.00, if you want assigning an operator to one or more groups you should buy Groups Module, $20.00, for canned replies add $10.00, tickets by email (this is not email piping) other $10.00, data exportation $10.00 more, etc.Talking about other alternative "free" PHP Support Tickets. It's a basic system that we tested some time ago, this system doesn't have "modules" all is integrated. if you check with attention it's mysql tables have small dimensions that are going to collapse, leaving unusefull the entire system, something not admissible in a business. In those cases you don't have to be a complete guru, but expert knowledge is required.
Facil HelpDesk as it's name says Easy in spanish, is a simple, full featured solution, it's price is affordable, not expensive, doesn't have restrictions nor functions that are going to fail at future.
Every time that you buy Software you gest service and professional care for good running of your software application, free software allows you to save money at the beginning, but there is no support, if at future you get problems you will have to read extensive documentation, read foros, ask for help at a community; it means waste your time in activities that are not of your core businees.
