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.

Cetaris

Vendor-source research

Cetaris is an enterprise fleet maintenance and asset management (CMMS/EAM) platform built around work orders, preventive maintenance, parts inventory, and a strong warranty-recovery module. It emphasizes ROI (reduced road failures, lower carrying inventory, higher labor productivity) and connects to 150-300+ external systems including ERPs, OEMs, fuel systems, DVIR providers, and telematics. It is genuinely maintenance-first software, not a telematics or GPS product.

Best fit
Large enterprise and mid-market fleets (transportation, distribution, grocery, oil & gas, utilities) that run a dedicated shop and want a maintenance/EAM platform focused on warranty recovery, parts optimization, and asset uptime ROI.

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.

Research position
Cetaris is a legitimate, maintenance-first fleet CMMS/EAM aimed at the enterprise end of the market, with deep work-order, PM, parts, and warranty functionality and strong customer-service reviews. It is not a native GPS/telematics vendor: location and fuel data arrive through integrations (Samsara, Geotab, fuel systems), so native_gps and native fuel tracking are false. Best fit for larger fleets with an in-house maintenance shop willing to invest in a detailed implementation; likely overkill and too costly for small fleets that just want simple scheduling.

Buyer fit, strengths and cautions

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

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
Cetaris logo

Cetaris

Cetaris is a legitimate, maintenance-first fleet CMMS/EAM aimed at the enterprise end of the market, with deep work-order, PM, parts, and warranty functionality and strong customer-service reviews. It is not a native GPS/telematics vendor: location and fuel data arrive through integrations (Samsara, Geotab, fuel systems), so native_gps and native fuel tracking are false. Best fit for larger fleets with an in-house maintenance shop willing to invest in a detailed implementation; likely overkill and too costly for small fleets that just want simple scheduling.

Potential strengths

  • Deep, mature maintenance/EAM feature set (work orders, PM, parts, warranty) proven at enterprise scale (Walmart, Swift, Loblaw, XPO)
  • Standout warranty-recovery and parts-optimization tooling that drives measurable ROI (users cite ~51% fewer road failures, 15% lower maintenance costs)
  • Strong customer service and high retention (reviewers praise long-term support staff; ~95% retention claimed)
  • Extensive integration ecosystem lets it sit at the center of an existing ERP/telematics/fuel stack

Cautions to validate

  • Enterprise pricing (from ~$1,000+/month, quote-based) and no free trial or free version make it inaccessible to small fleets
  • Implementation is detailed and time-consuming, with added cost for changes to the initial setup
  • Some reviewers feel overwhelmed by the volume of data the system expects them to collect
  • No native GPS/telematics hardware and no native fuel tracking or DVIR capture; these depend on third-party integrations

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.
