I caution anyone to buy from The Perfect POS. They are very unhelpful and condescending. They do not help with any troubleshooting even in the first month, and you get bet that the software will stop working after the one month is up, at which point you will never be able to get anyone to answer you again. I bought directly from them, so it's not a third party problem. Their first system was so bad that I exchanged it, and the second one only worked for about 45 days before error messages began and the software wouldn't load again. I called and waited on hold for 13 minutes just to finally get a voicemail and never get a call back 2 days in a row. This company is a scam. Just look at their reviews on other large consumer sites.
