Does AOTMP recommend historical bill audits?

Bill audits identify financial exceptions including over-billing, billing for disconnected services, and billing for unauthorized services. Identifying exceptions paves the way for credits, but audits don’t solve the root cause of the exception. To that end, taking steps beyond the audit to diagnose and mitigate exceptions before they appear on bills is a best practice. Historical telecom bill audits are not the full lifecycle management solution organizations need to drive comprehensive technical and operational efficiency.
