I like the way Roll Call is a whole church system - we bought it primarily to keep track of children's church but it is so much more than that. It is easy to teach and administer and has the flexibility to be modified for our needs. The back up assistance after purchase has been outstanding - no question is too trivial for the company to follow up. My every issue has been addressed and answered to my complete satisfaction. The company have also assisted us in acquiring the bar code scanners etc that we decided to use with the system, which allowed us to get them at a good price and with no questions as to compatibility.
