Creation/Revision Date: 30.01.2006 CANTO 2006 © 2006 ORGA Systems | All rights reserved | www.orga-systems.com We need to start putting systems in place that support revenue settlement We have outgrown our current system: It is too slow and the no. of „products“ becomes unmanageable Typical Drivers to Seek for a New Billing System We cannot launch convergent prepaid / postpaid products We have been told by internal audit that we have to get revenue leakage under control We cannot launch new products because it takes too long to change the billing system, even for simple things We have too many systems in place. We need to rationalize and reduce TCO We want to take on corporate customers BUT we cannot create complex billing hierarchies
