QBILLED is available as a Standalone or Distributed system.

The Standalone system is aimed at small to medium telecoms companies, handling between 2 and 4 million calls per day. For this option, the suite of customer management, invoicing, rating and business intelligence components are all installed onto one multi-processor server.

The Distributed system is aimed at larger telecoms companies, handling between 10 and 50 million calls per day. Here, there is the ability to operate as many rating engines in parallel (each on their own server) as necessary to achieve the volume processing required.
