I like that we have an app for all our clients (retail store & restaurant) - no more phone calls! The fact they are always updating their apps helps us keep up too :) It would be great if you could get notifications when your customers download something off yours website or even just log them into things so as soon as someone logs onto one thing i can message them from anywhere which saves me time. Nothing at this point really, everything works well however do contact support about any issues/bugs etc there may come across. Just make sure u know what ur doing before submitting anything because sometimes bugs will turn out better after testing than expected :). Retail management via the app has help streamline many aspects of running my business including stock taking, ordering food via delivery companies such as Foodora & UberEats, staff scheduling and communication regarding orders coming through both channels as well as keeping track.
