  1. You may consider adding Harbortouch to your list of free software offerings. While there is a monthly service fee for service and support, the actual POS hardware and software is “free” with a 3 year agreement. A little different model than you systems mentioned, but it’s very robust and full featured system. Thanks for your consideration. Cathy.
