Fleet Telemetry, Serialized Assets & Automated Billing for Temporary HVAC Rentals
A specialized web application for managing commercial heating and cooling equipment rentals with automated inventory tracking and customer billing.
Operational Constraints & What Was in the Way
Legacy friction, system bottlenecks, and functional limits requiring custom engineering.
Operational & Engineering Context
Supplying emergency temporary climate systems to hospitals, construction projects, and commercial complexes requires precision inventory tracking and complex pro-rated billing terms.
Identified Friction Points
Equipment frequently
remained on jobsites past contract end dates without automated billing triggers
Managing pro-rated rental periods (daily, weekly, monthly rates
with off-rent clauses) overwhelmed legacy accounting software
Field technicians
had no mobile visibility into equipment maintenance status or available warehouse stock
Execution Pipeline & Architectural Topology
