I will investigate and fix your telecom billing invoice data issues

Are your customer bill balances showing incorrectly after a corrective invoice or billing run? Seeing unexpected differences in opening balances across billing cycles? I can help. I have 10+ years of hands-on experience investigating and resolving complex billing data issues for telecom operators including corrective invoice failures, bill balance chain corruption, and multi-cycle data fixes.

What I offer: - Corrective invoice investigation & fix - Bill balance chain analysis & correction - Opening balance mismatch diagnosis - Multi-cycle data correction scripts - Root cause analysis & findings report - SQL-based data fix with account-by-account validation - Post-fix verification & sign-off support

Real example from production: A corrective invoice type was triggering a software bug that silently corrupted bill balances on all subsequent billing cycles. By the time it was caught, multiple bills were already incorrect. We identified all impacted accounts, rebuilt the balance chain sequentially, and corrected every affected bill without impacting live billing. Who this is for: Telecom operators or IT teams dealing with billing data inconsistencies, incorrect invoice balances.
