In the spring of this year I did alot of research and due to the high cost of a real pos system, the ones offered for around 1,000 just seemed okay, the real number was around 3,000. If your volumn is big then it can be justified. Look at NCR register system however that was cloud based and it seemed good, however I refuse to store my info on a "cloud"
So, I went to a better register that can download the info and the buttons are easily programed for updated prices. I have the square, pay-pal and micro soft card readers so you can accept cards.
pos is a little faster however I have the buttons simple and prices are tax included ex: pulled pork 7 brisket 8, combo 12
