What We Find

What Our Telecom Audit Reveals

How Our Telecom Invoice Audit Works

A telecom invoice audit is a systematic, line-by-line examination of every charge on your enterprise telecom bills. Unlike a quick spot check, our audit process compares each line item against your contracted rates, current market benchmarks, and actual service usage to identify billing errors, unused services, and cost optimization opportunities.

Step 1: Invoice Collection & Normalization. You upload your telecom invoices in any format — PDF, Excel, CSV, or even screenshots. Our team normalizes the data across all carriers (AT&T, Verizon, Lumen, T-Mobile, Comcast Business, and others) into a standardized format for analysis. This step alone often reveals discrepancies between what you ordered and what you are being billed.

Step 2: Rate Benchmarking & Contract Compliance. Every rate on your invoice is compared against your contract terms and current market pricing. We maintain a database of enterprise telecom rates across 37+ client environments and 1,092 locations, giving us unmatched visibility into what companies your size should be paying. Common findings include rates that exceed contracted amounts, legacy pricing that was never updated after renewals, and promotional rates that expired without notice.

Step 3: Service Inventory Validation. We cross-reference billed services against your actual usage and business needs. Industry data shows that 27% of enterprise telecom spend goes to services no longer in use — circuits at closed locations, backup lines that were never decommissioned, and features added during projects that ended years ago. These ghost services represent immediate, recurring savings.

Step 4: Error Detection & Recovery Analysis. Our telecom expense management experts flag every billing error with documentation sufficient for carrier disputes. Common errors include duplicate charges for the same circuit, incorrect taxes and surcharges, early termination fees billed on services still under contract, and bandwidth charges that exceed provisioned capacity. For enterprises managing telecom spend across multiple locations, these errors compound quickly.

Step 5: Savings Report & Action Plan. Within 48 hours, you receive a detailed telecom audit report showing every finding, the dollar impact of each issue, and a prioritized action plan for capturing savings. Our clients typically see 12-33% in recoverable savings — the same range we have documented across our portfolio of 37 enterprise clients with $36M+ in total savings achieved.

Whether you manage telecom for 10 locations or 1,000, a professional telecom invoice audit is the fastest way to identify where your money is going and how to get it back. Most enterprises that have never had an independent audit are surprised by the results — which is exactly why we offer this service at no cost and no obligation.
