The customer service has been great from the moment we started evaluating different solutions. They are always very responsive to our needs and provide excellent support. In addition to being able to manage our POS, they have also been developing an inventory management system as well which will be extremely helpful in future years. Nothing so far. We have had no issues with their product or service thus far. Their customer service is outstanding and we have not run across any issues. We are solving problems related to POS and inventory control.
