Friend, I'm on your side
For instance anyone who bought a point of sale system that runs windows xp or whatever other hardware is getting phased out will have to replace them all now for around 25-50k per machine. Yeah it's a write off but you've still got to come up with that bread(no pun intended, well maybe...).
You'll also have issues with the network and internet fairly frequently.So then what happens? You can't take orders, you close?
Also how do you deal with cash or are you no longer accepting cash? You're going trust customers in the till? In the hood? Everywhere isn't Martha's Vineyard. Nor is it Canada.
It gets pretty chaotic. Oh and you better pray there isn't a power outage.
I wouldn't want a customer touching one, G-d knows things break. Especially when you're throwing thousands of random idiots at them everyday.
And if they change their minds? Oh dear....friend.
