Case Study: Carnegie Mellon University achieves faster, more accurate billing and reduced revenue loss with Calero

Making it easy for the Carnegie Mellon Telecom team to identify billing errors and eliminate old and inaccurate data

Carnegie Mellon University’s Telecommunications Department struggled with slow, error-prone monthly billing: transferring 900+ directories via FTP and feeding billing data into accounting took multiple days and led to expired accounts and lost revenue. They engaged Calero and its Calero‑MDSL billing platform to improve accuracy and speed.

Calero implemented Calero‑MDSL with a customized accounting feed, account rollovers and an online departmental portal, shrinking bill generation to one day and the accounting feed to about 30 minutes. The solution made billing reports easier to navigate, uncovered previously unbilled Monthly Recurring Charges, eliminated distribution delays, and reduced revenue loss from roughly $500–$600 per month to under $100.
