An ELD and a TMS are not the same thing, and the best results come from pairing them well. The ELD records hours of service, location and vehicle data. The TMS runs loads, customers, invoices and driver pay. The integration between them decides whether your dispatchers see live truck status or spend the day calling drivers.
| Job | ELD / telematics | TMS |
|---|---|---|
| Hours of service logs | Yes | Reads HOS to plan loads |
| GPS location | Yes | Displays it on loads and customer tracking |
| DVIRs and vehicle diagnostics | Yes | May use for maintenance alerts |
| Load planning and dispatch | No | Yes |
| Invoicing and settlements | No | Yes |
| Customer visibility and EDI updates | Limited | Yes |
Motive, Samsara and Geotab are excellent telematics platforms, but none of them is a full carrier TMS on its own. You need both, working together.
All three are widely used and appear on FMCSA's list of registered ELDs. The right choice usually depends on factors other than the TMS:
The better question isn't which ELD is best. It's whether your TMS integrates deeply with the ELD you already have.
Tracx integrates with Motive, Samsara, Geotab and Verizon Connect, pulling location and status into dispatch, customer tracking and settlements. Because Tracx doesn't sell its own ELD hardware, you keep the telematics provider that already works for your fleet.
Can Samsara or Motive replace a TMS? No. They are strong telematics and compliance platforms, but they don't run the full load-to-invoice workflow a carrier TMS handles.
Should I pick my ELD or my TMS first? If you already have an ELD, pick a TMS that integrates with it. If you're choosing both, confirm the integration before signing either contract.
What is a native ELD integration? It's a direct connection maintained by the TMS vendor, as opposed to a file export or a custom project you pay to build.
