CAS is your web portal to manage your business.

CAS is short for Central Admin System. It's where you can make all the changes you need to operate your business. Changes made here will be reflected on all of your POS devices. Many of the changes you make on your POS will also be reflected here. CAS is also where you can access your transaction and inventory reports. 

You can access CAS from in the "Log-in" in upper right hand corner.
