Do not use them. It is a very expensive rip off.
They talk a big talk but when it comes down to it is a complete waste of time. We were supposed to get our money back when we did our taxes this year. When I showed the paperwork that I was given by GPS to my accountant she laughed and showed me where I was already claiming the deductions on my taxes. So a year after GPS was here to "help" my business I can look back and say that they were the dumbest business decision I have ever made.
Their money back guarantee is worthless. They will not be welcome back in my store under any circumstances.
Reason of review: Pricing issue.
Monetary Loss: $35000.
I didn't like: Anything from them.
