Case Study: Enersource achieves automated, accurate billing and cuts verification time from 5 hours to under 5 minutes with CaseWare Analytics' CaseWare Monitor

Caseware Monitor Dramatically Improves Billing Process For Energy Utility

Enersource, the energy utility serving more than 200,000 customers in Mississauga, faced a billing challenge after implementing a smart metering system that was incompatible with its legacy in‑house bill verification system (BVS). The old BVS required heavy computing power, took hours each day to verify bills, and routed anomalies by email with no efficient tracking. Enersource engaged CaseWare Analytics to deploy a new bill verification solution using CaseWare Monitor.

CaseWare Analytics implemented CaseWare Monitor to consolidate multiple data sources (print files, the core billing system and spreadsheets), perform independent bill calculations, and automatically route anomalies through a built‑in workflow and resolution tracking. The result: daily bill verification was reduced from five hours to less than five minutes, billing accuracy improved, manual reviews were eliminated, and management can now monitor error rates daily — with audit evidence stored centrally by CaseWare Analytics.
