Large-Scale Power Utility Contract-First Telecom Audit

About the Client A large-scale power company with hundreds of locations across rural service territory, requiring a diversified network of regional and national carriers to meet power customers' needs. The geographic footprint and carrier mix made it difficult to validate billing accuracy without a structured, contract-first audit.

The Challenge Persistent AT&T billing errors and rising POTS rates The client engaged Valicom to address persistent telecom billing inaccuracies and escalating service costs across an AT&T-anchored environment spanning more than 1,700 locations and nearly 20,000 services reviewed. The primary issue was ongoing AT&T billing errors, where numerous circuits were invoiced at rates that did not align with contracted pricing. On top of those discrepancies, AT&T had begun increasing rates on hundreds of POTS lines, creating growing cost exposure on services that were still operationally required to support a rural, geographically dispersed customer base. Without a contract-first audit and active dispute management, those errors and rate hikes would have continued to compound month over month.
The Valicom Solution A contract-first, circuit-level audit Valicom conducted a comprehensive audit of the AT&T environment and billing practices, working through 19,558 total services with a contract-first, circuit-level approach to re-engineer the cost base.
Contract & Rate Validation. Obtained and reviewed all AT&T contracts, then established expected contracted rates at the individual circuit level and compared them against live billing to surface discrepancies across all 1,741 locations.
Billing Dispute & Recovery Management. Identified multiple incorrectly billing circuits, submitted detailed disputes with corrected rates by circuit, and actively managed each through resolution, confirming accuracy on subsequent invoices.
POTS Cost Optimization. Confirmed business need with the client, then recommended and implemented an AT&T CompleteLink contract to lock in reduced rates across hundreds of lines, including preparation, submission, and execution end-to-end.
Delayed Implementation Recovery. When AT&T delayed rate implementation, Valicom filed additional disputes to recover the retroactive charges associated with the delay.
Why a circuit-level audit matters Carrier billing rarely fails in obvious ways. Errors hide in mismatched rate codes, expired promotional pricing, and post-renewal drift. By rebuilding the contracted rate for every circuit and comparing it against live invoices, Valicom turned an opaque AT&T bill into a line-by-line recovery and savings plan.
Quantifiable Business Impact Recovery, savings, and stabilized billing Across the three-year engagement, two parallel workstreams, circuit billing corrections and POTS optimization, delivered immediate one-time recovery and substantial recurring savings, with 50% of ongoing savings implemented in the first six months.
