Samsara

Vendor-source research

Samsara is an enterprise fleet telematics platform with an integrated Connected Maintenance module. Its maintenance workflows are built on top of native GPS and engine diagnostics, so live fault codes and driver DVIR defects feed directly into preventive maintenance schedules and work orders.

Best fit
Mid-to-large fleets that want telematics-driven preventive maintenance, where engine fault codes and DVIR defects flow straight into work orders on one platform.

Fullbay

Vendor-source research

Fullbay is cloud-based shop-management software built specifically for heavy-duty and diesel truck/trailer repair shops. Its core workflow runs the full service-order lifecycle: intake, technician labor tracking, guided inspections, parts authorization/ordering/inventory, preventive-maintenance and DOT-inspection scheduling, invoicing, and a customer portal. It is maintenance-first rather than a telematics platform, so it excels at work orders, PM, inspections, parts and repair-shop cost control.

Best fit
Heavy-duty truck and trailer repair shops (commercial diesel service providers) and fleets that run their own in-house heavy-duty maintenance shops.

Which product fits which kind of fleet?

This is a fit comparison, not a universal winner. A tool built for an enterprise fleet with native telematics is not the same as one built for a small in-house shop. Validate the decisive maintenance workflow and total contract cost in both demos.

Research position
Genuine heavy-duty maintenance software, not pure telematics. Fullbay is repair-shop-management-first (work orders, PM, DOT inspections, parts) so all maintenance facets apply. It has no native GPS/telematics hardware and no built-in fuel-card/fuel-tracking module, so those facets are false. Best fit for commercial heavy-duty repair shops and fleets operating their own diesel shops; a company only wanting vehicle GPS tracking should look elsewhere.

Buyer fit, strengths and cautions

Research interpretation based on current positioning and official documentation—not a substitute for implementation references.

Samsara logo

Samsara

A strong fit for fleets that want maintenance and telematics unified, but overkill if you only need standalone maintenance software without hardware.

Potential strengths

  • Maintenance is tightly integrated with best-in-class native telematics and engine diagnostics
  • Fault codes and DVIR defects automatically generate actionable work orders, reducing manual entry
  • Single platform covers tracking, compliance (ELD/HOS), inspections, and maintenance
  • Strong Capterra rating (4.5) across a very large review base

Cautions to validate

  • No public pricing; requires a custom quote and typically a multi-year hardware contract
  • Requires Samsara hardware/gateways, so it is not a lightweight standalone maintenance tool
  • Value-for-money is the lowest-rated dimension in user reviews
  • Best economics favor larger fleets, less suited to very small operations

Fullbay

Genuine heavy-duty maintenance software, not pure telematics. Fullbay is repair-shop-management-first (work orders, PM, DOT inspections, parts) so all maintenance facets apply. It has no native GPS/telematics hardware and no built-in fuel-card/fuel-tracking module, so those facets are false. Best fit for commercial heavy-duty repair shops and fleets operating their own diesel shops; a company only wanting vehicle GPS tracking should look elsewhere.

Potential strengths

  • Purpose-built for heavy-duty/diesel repair shops with a deep, guided service-order workflow
  • Strong preventive-maintenance, DOT-inspection and parts-inventory capabilities
  • Highly rated customer support (4.8/5 for customer service on Capterra) and QuickBooks integration

Cautions to validate

  • No native GPS/telematics or fuel tracking, so it is not a substitute for a fleet-tracking platform
  • Extra charges for additional users and data migration can raise cost for smaller shops
  • Reporting is reported as limited compared with dedicated accounting tools like QuickBooks

Run the same demo with both vendors

A fair comparison uses identical data and workflow scenarios.

  1. PM-to-work-order: Set a preventive-maintenance schedule by mileage and engine hours, then confirm a due service opens a work order automatically.
  2. Inspection defect: Complete a mobile DVIR with a failed item and follow the defect through to a closed repair without re-keying.
  3. Parts & cost: Add parts and labor to a work order, then produce a cost-per-vehicle and downtime report.
  4. Meter capture: Import odometer or engine-hour data from a fuel card or telematics integration and confirm PM stays accurate.
  5. Exit test: Export vehicles, service history, parts and inspection records in documented formats.
