I stumbled across this website while doing research on inventory software for my optical shop. I specifically did not want any big, bundled programs but only pure inventory. Therefore, I was open to all alternatives. However, when I found their website and watched their videos I was very impressed with the software. It's a pretty robust inventory system but it's also a complete optical shop management system. They also have modules for appointments, billing etc. The program is entirely web based, has an easy interface and is entirely free. There are some "catches" but not anything significant. If anyone has tried them out I would be very interested to hear more about them. So far, I was more impressed with this free product than I have been with several paid products that I've seen.
