Years and years ago, we used to have a small business. It would have made things so much easier if we’d had POSGuys, but back then there weren’t any stores or businesses that I know of that had scanners.
Barcode scanners have simplified things so much, especially since so many businesses are computerized. And one really great benefit is when it is time to do inventory. (That was always such a pain!) A scanner would make doing inventory so much easier!
