Tellennium review
Broad enterprise telecom expense coverage spanning invoices, assets, contracts and service changes.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Tellennium provides telecom and technology expense management through its Management of Things SaaS platform and managed services. It is aimed at enterprises with complex telecom estates, where finance, IT, procurement and network teams need shared control over costs and services. The platform covers invoice processing, telecom inventory, allocation, contracts, orders, reporting and service changes, alongside auditing, optimization, provisioning and mobility management. Founded in 1999, Tellennium is based in Mt. Washington, Kentucky.
The main distinction is lifecycle breadth. Automated invoice collection, validation, reconciliation and payment workflows sit alongside audits for billing errors, overcharges and unused services. A continuously updated inventory tracks circuits, services, devices, numbers and assets; cost allocation and financial reporting add budgeting, trending and forecasting. Contract adherence monitoring and renewal notifications connect expense oversight with procurement, while order workflows cover configurable moves, adds, changes and disconnects. Dashboards, discrepancy queues and drill-down views support investigation, with mobility asset, invoice, contract and fulfillment management included in the same scope. This makes Tellennium a fit when disconnected telecom processes are the problem, rather than a narrow invoice-audit need.
The offering is cloud-based, available through web and API, and integrates with ServiceNow and APIs. Support channels include email, chat and phone, and the description also identifies dedicated U.S.-based teams for its services. According to the vendor's pricing information, prospects are directed to request information or a demo rather than choose from standard software plans. That sales-led approach, plus the breadth of workflows, suits organizations prepared to evaluate an enterprise service with multiple stakeholders. Smaller teams looking for a lightweight, self-service expense tool may find the scope and buying process a poor match.
