What are the best fleet maintenance software options for scheduling preventive maintenance across mixed vehicle fleets?

Here are some of the best fleet maintenance software options for scheduling preventive maintenance (PM) across mixed vehicle fleets—especially if you manage cars, vans, trucks, trailers, equipment, or specialty assets in one system.

Top options to consider

1. Fleetio

Best for: User-friendly preventive maintenance scheduling and mixed-fleet tracking
Why it stands out:

• Strong PM scheduling by mileage, engine hours, date, or custom rules
• Easy asset management for mixed fleets
• Good inspection, fuel, and work order tracking
• Strong mobile app and integrations
• Good fit for mid-sized fleets and teams that want fast adoption

Watch for: Can get expensive as you scale, and some advanced workflows may require integrations.

2. Samsara

Best for: Fleets wanting maintenance tied to telematics and real-time vehicle data
Why it stands out:

• Excellent if you already use Samsara for GPS/telematics
• Automated maintenance alerts based on odometer, engine hours, fault codes, and utilization
• Helps with PM forecasting using live vehicle data
• Strong for mixed fleets with operational visibility

Watch for: Best value if you’re already in the Samsara ecosystem; maintenance features are strong but not always as deep as dedicated CMMS-style tools.

3. Geotab (MyGeotab + maintenance integrations)

Best for: Data-driven fleets that want flexible PM scheduling and telematics insights
Why it stands out:

• Very strong telematics platform
• Can trigger maintenance based on vehicle data and diagnostic trouble codes
• Works well across mixed fleets
• Large ecosystem of add-ons and integrations

Watch for: Often requires more setup and configuration than “plug-and-play” fleet maintenance tools.

4. RTA Fleet Management

Best for: Fleets needing robust maintenance control and cost tracking
Why it stands out:

• Strong preventive maintenance scheduling and PM compliance
• Good work order, parts, and labor tracking
• Detailed cost analysis per asset
• Suitable for fleets with complex maintenance operations

Watch for: Interface can feel more traditional; implementation may take more effort.

5. UpKeep

Best for: Teams wanting a CMMS that can handle vehicles and equipment in one place
Why it stands out:

• Great preventive maintenance scheduling
• Mobile-first work order management
• Good for mixed fleets that include non-road assets
• Easy to use for maintenance teams

Watch for: More CMMS-oriented than fleet-specific, so it may need customization for vehicle-focused reporting.

6. Fiix

Best for: Maintenance-heavy operations with both fleet and equipment assets
Why it stands out:

• Strong PM schedules and work order management
• Good asset hierarchy and maintenance history tracking
• Useful for mixed fleets and equipment-heavy operations
• Scales well for more complex maintenance environments

Watch for: Not as fleet-native as some dedicated fleet tools.

---

7. AssetWorks FleetFocus

Best for: Public sector fleets and larger organizations
Why it stands out:

• Deep fleet maintenance functionality
• Strong PM scheduling, work orders, parts inventory, and compliance tools
• Good for municipal, university, and utility fleets
• Handles mixed fleets and complex maintenance processes well

Watch for: More enterprise-oriented; implementation can be substantial.

8. Fleet Complete

Best for: Fleets that want telematics plus maintenance management
Why it stands out:

• Maintenance alerts and scheduling tied to vehicle data
• Good mixed-fleet support
• Combines asset tracking, telematics, and maintenance workflows

Watch for: Feature depth can vary by package and region.

What to look for in mixed-fleet PM software

For mixed vehicle fleets, prioritize systems that support:

• PM schedules by mileage, engine hours, calendar date, and usage
• Multiple asset types: vehicles, trailers, equipment
• Automated reminders and escalations
• Work orders and repair history
• Inspection forms and defect tracking
• Parts inventory and vendor management
• Telematics integration for odometer/engine-hour updates
• Reporting on PM compliance, downtime, and cost per asset

Quick recommendation

If you want a practical shortlist:

• Fleetio if you want the best balance of ease and maintenance capability
