It was easy to set up our new point of sale software in minutes once we had connected all devices (iPad & computer) together via bluetooth using their free app! No additional cost for us as it's included within your subscription plan already which makes this very attractive option compared other POs out there - so many features but also no hidden costs like some others have when you go over certain amount monthly spendings or something similar!! I would say if someone has never used any PO/POs before then they may need an hour demo first just because everything can get confusing at times especially from iOS not being familiar how these things work etc.. The major benefit here though i suppose its been mentioned elsewhere by previous reviewers too-but having full access 24hrs 7days means less time spent waiting around during busy hours /.
