A Calero Case Study
Henry Ford Hospital, a large Detroit health system, faced poor visibility and control over its telecom estate after an initial TEM provider could not validate invoices to contracts, produce meaningful reports, or provide call accounting and wireless reporting. Seeking a fully integrated TEM and call accounting solution, Henry Ford Hospital engaged Calero (Calero-MDSL) to address these gaps.
Calero implemented its integrated expense management software and managed services, building inventory and bringing wireline and wireless systems online in two months, deploying call accounting across 30,000 stations and automating chargeback reporting. Calero’s solution eliminated spreadsheet-driven processes, freed staff for mission-critical work, and delivered measurable savings — $160K in initial wireless optimization, $250K in annual voice optimization, $900K wireline and $600K wireless in year one (totaling $1.5M in year one) and over $4M in hard savings by year six.
