I have used Lankar for many years now and have to say it is the smoothest shop management software I have seen. I purchased the system years ago, but they have a pay as you go setup now. I still pay a support fee each month, but it worth it for the peace of mind, computers being what they are. The few times I have had to use the support, it has been flawless. Very quick to respond, and quick to resolve the issue. I do backup my data every few hours so that makes a difference if something does go wrong. The support staff has never been rude or unresponsive to me or any of my staff. If they had more stars I would give it to them.
