Dedicated Fleet Service—Delivered at Your Facility.
Sigma Fleet Services develops recurring on-site service programs for fleets with predictable maintenance volume and sufficient operating scale. Technician coverage, service cadence, eligible work, vehicle staging, approvals, and documentation are structured around the customer's facility and operating schedule.
Put Fleet Service at the Center of the Operation.
Traditional service requires vehicles to leave the operating location, employees to coordinate transportation, and fleet leaders to manage work across multiple appointments. Dedicated on-site service brings recurring technician coverage directly to the facility. The result is a structured service relationship built around the fleet's maintenance demand—not a series of disconnected mobile visits.
Predictable Coverage
Establish recurring service windows based on fleet size, maintenance volume, operating schedule, and market capacity.
Reduced Vehicle Movement
Complete eligible work where vehicles are normally staged, reducing unnecessary trips to an outside repair facility.
Consolidated Service
Group preventive maintenance, inspections, diagnostics, and eligible repairs into coordinated on-site service periods.
Consistent Workflows
Use defined processes for vehicle staging, technician access, repair approvals, documentation, and shop referrals.
Use the Right Service Model for the Work.
