Questions merchants ask
Do I need a particular till or touchscreen?
No. It runs on the PC, laptop, Mac or tablet you already have. The only extras a counter needs are a barcode scanner and a receipt printer.
What happens if two tills sell the last one while offline?
Both sales complete, and the stock figure goes negative when they sync so you can see it and sort it, rather than one of them being refused at the counter.
Does the app update itself?
Yes. Updates download in the background and apply when the device has been idle for a few minutes with nothing in progress.
