Core service areas: telecom, mobility, utilities, and SaaS
From Telecom to Technology Expense Management
Tellennium began as a telecom expense management company, helping clients understand what they were paying for, identify unnecessary expenses, and manage their services more efficiently and effectively.
As enterprise technology environments changed, we grew with them. We expanded into managed mobility services, utility expense management and utility bill management, and SaaS License Management.
That growth reflects the broader evolution of TEM from telecom expense management to technology expense management, along with our continued focus on responding to what our clients truly need.
Built for Complex Enterprise Environments
Our work spans telecom, mobility, utilities, SaaS, cloud, and other recurring enterprise technology expenses. Our capabilities include detailed inventory, invoice management, contract and renewal tracking, audit and optimization, and ongoing lifecycle support.
Our Management of Things® (MoT®) platform supports telecom, mobility, and utility expense management. For SaaS License Management, we use specialized technology to help clients identify applications and subscriptions, align licenses with business needs, and manage renewals.
Our technology is supported by experienced subject matter experts who help clients manage the details, identify opportunities, and take action. Our support teams are U.S.-based, and every client works with people assigned to their account who know their environment.
An Optric Company
Tellennium is an Optric company. Optric brings together strategic sourcing of carrier services, connectivity, cloud, cybersecurity, and managed IT services through a more unified approach.
For Tellennium clients, this means more options, broader expertise, and more ways to address their technology needs. Tellennium’s culture, MoT platform, experienced team, and commitment to clients continue, supported by Optric’s additional resources and capabilities.
Our Focus Remains the Same
What began with a focused mission in telecom expense management has grown into a trusted enterprise technology expense management partner. Our role remains straightforward: help clients understand what they have, what they are paying for, where improvements are possible, and what action to take next.
“They know the marketplace. They know the vendors. And, they are our advocate.”
