Tellennium

Tellennium has run managed expense programs from Louisville, Kentucky since 1999, and it is the rare managed provider that built and still owns its own software. The Management of Things platform runs invoice processing and payment, audit and optimization, inventory, cost allocation, and order workflows, with mobility, utility, and software license spend added over time and a ServiceNow integration since 2024. Unusually, the company explains its pricing model in public: a percentage of monthly spend that slides down as the estate grows, a share of what the audit recovers, and per device rates for mobility, with no long term lock in and US based support. It reports average recovered spend near thirty percent and was a representative vendor in the analyst market guide for expense management for three consecutive years. The caution is corporate. Tellennium was taken into an investment group's portfolio in late 2024 and rebranded under a new parent brand in mid 2026, so a buyer should ask which team, platform, and terms survive the integration before signing a multi year agreement. For a company that wants a hands on program across every kind of recurring technology invoice, it remains a strong contender.
