I bought this POS software for my store and it's been working pretty well so far (see below for demo). An additional feature I would like to add is scanning barcode using mobile devices.
I want to have a camera icon beside the "plus" sign. When clicking on the icon, a window pops up which enables me to scan the barcode. Once the barcode is detected, the window closes instantly and the product automatically being added to the shopping list. (see screenshot)
