After a bad experience in a previous restaurant with POS i was very hesitant to have one of these systems installed in my new restaurant. I have witnessed how costly these systems can be to repair and support and did not want to incur these sames expeneses time after time. However I must say that the staff at vitabyte has been very helpful in getting my store up and running. They offer monthly service contracts which allow you to pay a monthyl fee and recieve unlimited tech support, troubleshooting etc. This leaves me with peace of mind that if something goes wrong I am covered!
