When Three Metering Head-Ends Become One Auditable Billing Flow
How iTANZ modernized Oracle Utilities at multi-million-customer scale and stayed to run the billing cycle.
The Problem
A revenue engine cannot modernize at the expense of billing continuity or auditability.
- Three separate head-end vendors had to feed one governed meter-data flow.
- The move from CC&B to Customer Cloud Service had to protect account, meter and financial reconciliation data.
- Meter determinants needed to remain clean, explainable and provable before becoming charges.
- The operating model had to extend beyond go-live into ongoing billing-cycle assurance.
The Solution
Modernize the billing core, normalize meter data, prove the cycle, then stay for operate.
- Designed the target CCS architecture around deterministic, reproducible rating.
- Consolidated three head-end feeds into Oracle MDM with validation and estimation/editing rules.
- Used Oracle integration patterns, parallel-run and balance-to-balance controls as migration safeguards.
- Continued operating the production cycle after transformation.

Impact We Created
The delivery proof is described at multi-million-customer scale.
Three metering head-end vendors were consolidated into Oracle MDM.
iTANZ now runs the billing cycle rather than ending accountability at go-live.
Rating remains deterministic and reproducible.
The Conclusion
The hard part of utilities modernization is keeping the revenue engine trustworthy while everything around it changes.
