It was easy to use from day one! The whole process made everything super effortless - my entire staff loves it too because they know what’s coming in an out so quickly as well :) Nothing at all unfortunately. I would just love another year behind us though so we can get used to how powerful this tool really has been!! We have saved thousands since starting using e-rewards cards but also helped our clients save when sending them their way via email/text messages through text links which are set up within minutes after setting things straight (as per client request!). Easy to use website makes it easy even if you have no experience at all in this field! Customer service response was quick as well!! I would say there are not many features which can be customized according their needs but overall its good so far. Its very helpful when your business has more than one location then using mobile app will help save time and effort while managing everything from just 1 place itself. !
