Years Tax Experience

Telecom billing is uniquely complex — and costly errors hide in plain sight.

Tangoe Tax Audit is designed to identify and eliminate erroneous charges from your run rate immediately and recover what you’ve already overpaid — this is not a long-term project, it’s a fast-acting engagement. Telecom tax billing is layered with federal, state, and local regimes, carrier-imposed surcharges, and constant regulatory change, creating conditions where overcharges are common and often go undetected for years. Even enterprises with mature IT Expense Management, AP, and tax controls can unknowingly absorb erroneous charges when a carrier misapplies a classification, jurisdiction, exemption, or surcharge methodology. Standard telecom audits don’t look here, and most organizations lack the specialized expertise to challenge carriers effectively.

Misapplied Taxes

On non-taxable or misclassified services often persist undetected for years.

Billing Classification Errors

Across jurisdictions and service types, compounding month after month.

Carrier Surcharge Errors

Applied with limited transparency and rarely challenged without specialized expertise.

No cost. No risk. Savings-led from day one.

Every engagement begins with a complimentary assessment — no obligation if no opportunity is found. If savings are identified, the engagement proceeds on a pure contingency basis.

No savings, no fees — zero engagement risk.

No Carrier Changes

Contracts, circuits, and services remain untouched.

Minimal Client Lift

We handle analysis, disputes, and carrier follow-through.

paid, often going back years.
