Tellennium —
TEM, Managed Mobility & Utility Expense Management

Tellennium is a technology expense management company providing Telecom Expense Management, Mobile Managed Services, and Utility Expense Management for mid-market and enterprise organizations. Tellennium's platform — MoT (Management of Things) — handles invoice processing, inventory management, dispute resolution, and cost optimization across wireline, wireless, and utility spend. Unlike software-only TEM platforms that require internal staff to operate them, Tellennium delivers TEM as a fully managed service where their team handles the invoice audit, carrier disputes, and reporting on behalf of the client. Fibi sources and advises on Tellennium alongside other TEM and managed mobility providers at no cost to you.

Tellennium TEM covers the full lifecycle of wireline and wireless telecom invoice management — invoice receipt and validation, GL coding and cost allocation, inventory management, contract compliance auditing, dispute identification and resolution, and optimization recommendations. The MoT platform ingests invoices from all carriers, validates charges against contracted rates and active inventory, flags discrepancies for dispute, and provides management reporting on telecom spend by location, service type, and cost center. For organizations managing dozens of carrier invoices monthly across MPLS, DIA, SIP, and legacy voice circuits, TEM eliminates the manual effort and error risk of managing telecom invoices without a dedicated platform and team. Tellennium's managed approach means clients do not need internal TEM analysts to operate the system.

Tellennium Mobile Managed Services provides end-to-end management of enterprise mobile device programs — covering mobile invoice processing, carrier plan optimization, device procurement assistance, MDM integration, and usage reporting across all carrier relationships. The managed service handles the monthly operational burden of mobile expense management: processing carrier invoices, identifying users on suboptimal rate plans, flagging unused lines and devices, and providing the reporting finance and IT teams need to manage mobile spend. For organizations with large mobile fleets across multiple carriers, Tellennium's managed approach replaces a resource-intensive internal process with a dedicated team and platform that maintains continuous optimization rather than annual plan reviews.

Tellennium Utility Expense Management extends the same invoice audit and expense management approach used for telecom to utility bills — covering electricity, gas, water, and other utility invoices for multi-site organizations. The service includes invoice validation against contracted utility rates, audit of meter charges and billing calculations, identification of billing errors and overcharges, and dispute filing with utility providers. For organizations operating multiple facilities with significant utility costs, utility expense management applies the same systematic review to utility invoices that TEM applies to telecom invoices — recovering billing errors and providing visibility into utility spend that is often managed inconsistently across sites. Combining utility expense management with TEM and mobile managed services under Tellennium creates a single managed expense program for all major technology and facility utility costs.

MoT — Management of Things — is Tellennium's proprietary technology expense management platform, described as one of the most robust TEM platforms available for mid-market and enterprise organizations. MoT provides the invoice ingestion, inventory database, contract repository, cost allocation, dispute tracking, and reporting functionality that underpins Tellennium's managed TEM service. The platform maintains a detailed inventory of all active telecom services, matched to carrier invoices, with historical tracking of changes, disconnects, and additions. Reporting provides cost visibility by location, service type, business unit, and GL code for finance and IT stakeholders. Because Tellennium operates MoT as a managed service, clients benefit from the platform's capabilities without needing dedicated internal staff to learn and operate TEM software.
