Source-linked differences for fleet and maintenance managers. No sponsored winner and no blended review score.
Simply Fleet is a mobile-first fleet maintenance platform for small and mid-size operators, covering preventive maintenance, inspections, work orders, parts, and fuel. It emphasizes low per-vehicle pricing and a free tier for very small fleets.
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.

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.

These items come from vendor documentation. Treat them as a demo agenda, not proof of workflow quality.
Research interpretation based on current positioning and official documentation—not a substitute for implementation references.
A strong budget-friendly fit for small fleets that need core maintenance management without paying enterprise rates.
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.
