Fleet Support Built Around Daily Dispatch.
Sigma Fleet Services helps Amazon Delivery Service Partners protect vehicle availability through coordinated repair, preventive maintenance, mobile service, inspections, managed fleet care, and temporary rental capacity. Our approach is built around high-utilization delivery vehicles, route coverage, and the operational cost of downtime.
Downtime Does More Than Remove a Vehicle.
When a delivery vehicle becomes unavailable, the effect reaches beyond the repair itself. Route coverage, driver productivity, service commitments, and daily operating capacity can all be disrupted. Sigma evaluates service needs from an operator's perspective—considering vehicle condition, dispatch requirements, operational urgency, and the fastest practical path back to productive service.
Route Coverage
Maintain sufficient vehicle availability to support scheduled routes and daily dispatch requirements.
Driver Productivity
Reduce the time drivers and managers lose coordinating repairs, moving vehicles, and finding temporary replacements.
Fleet Readiness
Use planned maintenance and inspections to identify issues before they become preventable service interruptions.
Operating Capacity
Protect the number of vehicles available for normal operations, peak periods, and unexpected demand.
One Coordinated Fleet-Support Model.
Sigma combines repair, maintenance, mobile service, inspections, fleet coordination, and replacement vehicles within one operating relationship. Services can be configured around fleet size, vehicle mix, duty cycle, location, and daily operating requirements.
Fleet Repair & Diagnostics
Commercial vehicle diagnostics and repair for mechanical, electrical, braking, suspension, cooling, and drivability concerns. Service is coordinated around vehicle condition, operational priority, and return-to-service requirements.
Learn moreMobile Fleet Service
Planned maintenance, diagnostics, inspections, and eligible field repairs performed at the customer's operating location. Mobile service reduces unnecessary vehicle movement and helps keep minor issues from creating larger disruptions.
Learn morePreventive Maintenance
Structured maintenance programs aligned with mileage, duty cycle, operating conditions, and vehicle requirements. Planned service helps improve reliability, control maintenance timing, and reduce avoidable breakdowns.
Learn moreInspections & Defect Resolution
Annual inspections, vehicle-condition reviews, and coordinated correction of identified defects. Issues can be documented, prioritized, and routed into the appropriate repair workflow.
Learn moreManaged Fleet Care
Ongoing maintenance planning and service coordination for fleets requiring greater consistency and visibility. Programs may include recurring service schedules, vehicle-status coordination, defect management, and dedicated on-site support.
Learn moreRental & Replacement Capacity
Commercial cargo vans and step vans for breakdown replacements, seasonal demand, and temporary vehicle shortages. Flexible rental capacity helps protect route coverage without permanently expanding the fleet.

Vehicle Down Before Dispatch
When an unavailable vehicle affects the day's operation, Sigma helps assess the service requirement, determine the appropriate response, and coordinate repair or temporary replacement options.
Recurring Vehicle Issues
Coordinated diagnostics and repair planning help address underlying causes instead of repeatedly treating symptoms.
Peak and Seasonal Demand
Temporary rental vehicles provide additional capacity when route volume increases, fleet availability tightens, or permanent vehicle acquisition does not make financial sense.
Preventive-Maintenance Backlog
Sigma can help organize overdue maintenance by vehicle priority, mileage, operating schedule, and service requirement.
A Fleet Program—Not a Series of Repair Orders.
For larger DSPs and multi-location operators, Sigma can structure fleet support around the entire operation rather than handling each vehicle as an isolated transaction.
