Easy to use, great customer service, great price, easy integration with Sage 100 accounting software. Nothing so far. We have been working with them for about 3 years now and there has not been much change in the way they do things or how we can benefit from their services. They are always looking out for new ways of doing business that will improve our bottom line. As an independent restaurant with a limited budget, they have helped us save money while increasing sales at the same time. They are very professional, responsive and easy to work with. I highly recommend them! We are able to track everything from point of sale all the way through accounting.
