Just wanted to say, please include some technical information if possible.
I've spent time with and looked into developing for Clover and set up other POS systems. I've also tutored people pursuing their CS degree while bartending that want to make their own system. I'm very interested in this space since it seems impenetrable. Small businesses can't take too many risks and trying to sell a tailor-made POS seems impossible. Obviously the situation is different, though.
