National fleet maintenance. One accountable partner.
Sigma Fleet Services designs and coordinates maintenance programs for large, distributed commercial fleets—combining centralized governance, market-level execution, and clear operating visibility.
Control without losing local speed.
Enterprise fleets need more than a repair vendor. They need consistent intake, authorization, execution, documentation, escalation, and reporting—without slowing the field operation.
Centralized program control
One intake and escalation model across facilities, markets, and operating teams.
Regional execution
Direct Sigma operations and coordinated service coverage aligned to vehicle location and need.
Performance visibility
Program reporting structured around downtime, repair cycle time, preventive maintenance, and recurring defects.
Compliance discipline
Documented inspection, defect, authorization, and maintenance workflows built for auditability.
A disciplined rollout from discovery to governance.
Fleet discovery
Assets, duty cycles, locations, vendors, failure patterns, and operational constraints.
Program design
Service scope, authorization limits, PM standards, communication, and escalation rules.
Market activation
Launch sequence, site contacts, intake channels, technician coverage, and replacement planning.
Performance review
Operating reviews focused on downtime, cycle time, compliance, cost, and corrective actions.
For operations leaders
Reduce vehicle-down friction, establish escalation ownership, protect route and field capacity, and create a consistent maintenance rhythm across operating locations.
For procurement and finance
Consolidate accountability, define authorization controls, improve invoice context, and evaluate program performance using agreed operating measures.
