The single worst POS available
A year ago, my card reading device went down. After 2 hours of waiting on hold, they informed me that they would ship me another. It would of course take 4-5 days, in the mean time, my servers could still manually type in the 16 digit code, zip, expiration, and 3 digit security code. It was insane. Then they have the audacity to be the HIGHEST percentage and fees in any major POS system. Then on top of that, they randomly charge you a 2k fee without any direct contact. "Sir, we posted on our website that this charge was going to happen. It's sort of an existing charge, but not really. We want to make sure that you never have any downtime with your POS (hold the laughter). But honestly sir, our stock desperatly needs this, we keep missing our goals, so the only way to make them is to squeeze customers of ours". Please, if you've ever taken advice from an online review, RUN FROM Shift4! There will be no good that comes from working with them, I promise you.
