A whole lot of change has befallen the POS (point of sale) industry. The industry has been flooded with new competition from payment ISOs and agents entering the market, as well as new tablet-based POS apps. Mobility has generated a lot of buzz with merchants, as has omni-channel retailing and the need for heightened customer engagement. All these changes, whether they’re occurring to a greater or lesser effect with your c ustomers, mean your business has to change. Gone are the days of selling basic POS hardware and software. You’ve probably already made adjustments to your business. However, there’s probably one area you’re not addressing as well as you should.
