Verizon Business this week will launch a comprehensive telecom expense-management service, the first such offering from a major carrier.

The Verizon Business Integrated Telecom Expense Management Service is a suite of managed services that let corporate and government customers monitor, analyze and track telecom service expenses for their wireline and wireless services. The TEM service lets users track circuits, WAN routers, wireless rate plans and handheld devices.

"Enterprise users are expected to spend $550 million on telecom expense-management tools and services this year," says Eric Goodness, vice president of research for Gartner's managed and professional network-services organization.

That's $105 million more than was spent in 2005, so customers are willing to spend to save. But will they be willing to buy such tools from one of the carriers behind those cumbersome and often incorrect bills?

Some users seem skeptical, but Verizon Business is giving it a try.

Verizon is using different platforms to track wireline and wireless services.

"No other carrier has made a formal announcement about a discrete, focused market offer for multicarrier TEM services," Goodness says. "It's a very powerful offer."

Verizon has teamed with Symphony Services, which has developed an analytical software platform to track wireline services from a number of service providers. The tool keeps track of lines, circuits, customer premise equipment and WAN gear. The platform lets Verizon provide inventory asset tracking, contract administration and bill auditing.

That means that Verizon Business, on behalf of its customers, will review all telecom invoices and note any errors. When asked what happens when errors are discovered on Verizon bills, the carrier says they will be dealt with the same way as if they were found on any other carrier's bill.

"We're trying to take a nonpartisan view and treating Verizon Business no differently than any other vendor so we don't get into a 'fox watching the henhouse' scenario," says Cliff Cibelli, group manager of managed network services.

And like many telecom bill auditing firms, Verizon Business will provide dispute resolution and remediation, the latter as an add-on service for customers.
