We're a fabric store and we use the app to cut fabric at one register and save the customer's cart. They can keep shopping and then checkout at another register.
I just wish that the app would automatically release inventory when loading a cart (Instead of offering you the choice to keep the hold). This might not matter for some use cases and probably doesn't for restaurants, but for a retail store we think having the option is strange. It isn't a big deal, we just don't use the option.
Great app and the only one that way to easily start an invoice on one device and finish it on another.
It's great! Not too deep. Simple interface and well thought out. Even my Jpn staff can use it. No documentation though so not sure about a few things about Tab Update".
