We used a free helpdesk solution which was very good, but lacked sophisticated features such as locations, assets, and strict client/tech rights management. I demo'd at least a dozen offerings but couldn't find one that met our requirements for our budget. Then one day, I decided to throw in the towel. For the price I was willing to pay, nothing was going to workout. It so happened on this very day I stumbled upon WebHelpDesk. In a few seconds a chat window popped up asking if I'd like to demo the WebHelpDesk system. I honestly wanted to say no. To my surprise, it exceeded our expectations, and at an affordable price. Today, we run a more efficient Helpdesk than many of our own service companies. I have even recommended it to them. Although this is a Windows site, we are using Suse Linux Enterprise 10. We have used it Windows and it also works well on that platform.
