You would have to ask them why they don't publish the additional licence price, my best guess would to either avoid confusion or maybe they quote you on how many extra licences you want, ie the more you want the cheaper they get
They did tell us that it is based on there QuickTrack Asset Tracking software, but they charge schools less than normal.
We allow older students to use the software to book there items in and out, but they told us recently they are adding a new Users function that will block students from accessing 75% of the features and just allow them access to the booking screen
