Yard management vs WMS vs TMS
Distribution and manufacturing buyers often evaluate yard software alongside warehouse and transportation systems. Each platform has a clear boundary. Understanding where one stops and the next begins prevents buying software that manages inventory inside the building but not trucks in the lot.
Comparison
Three systems, three boundaries
Transportation management plans freight between facilities. Yard management runs operations from gate-in through gate-out. Warehouse management executes inventory tasks inside the building. Most mid-size and enterprise sites run two or three of these — integrated at the dock and in closeout.
| System | Primary job | In the yard |
|---|---|---|
| YMS (yard management) | Truck visits — gate, yard spots, doors, dwell, documents, gate-out | Primary for everything outside the warehouse door |
| WMS (warehouse management) | Inventory, locations, receiving, putaway, picking, shipping | Knows dock door status; does not track trailers in staging lanes |
| TMS (transportation management) | Loads, routes, carrier selection, freight cost | Plans arrival; does not capture gate facts or run the yard map |
| Dock scheduling (standalone) | Appointment slots and door calendars | Booking only — no gate capture, yard map, or ERP closeout |
Integration
How YMS and WMS connect at the dock
The dock door is the integration point. The YMS tells the WMS which trailer is at which door, with gate-captured PO and freight context. The WMS executes receiving or shipping tasks inside. When work completes, closeout events flow back — departure timestamp, ASN, receipt confirmation — without manual re-entry.
When you need YMS
Signs you need yard management — not just WMS or TMS
If gate teams maintain a separate log from dock scheduling, dwell is discovered at shift change, or finance reconstructs departures from emails — you need a YMS layer. If trailers sit in staging with no live map, door assignment happens by radio, or carriers call the gate for every status update — yard management software addresses the gap WMS and TMS were not designed to fill.
- Gate capture lives outside your WMS
- Yard spots tracked on whiteboards or not at all
- Dwell costs visible only after the fact
- Carrier status requires phone calls to the gate
- Closeout data retyped into ERP manually
Flodock
Flodock as the yard layer
Flodock is yard management software delivered as a suite on a connected yard platform. It connects gate, yard map, dock, dwell intelligence, carrier booking, and ERP closeout on one orchestrated visit — it does not replace inventory management inside the warehouse.

FAQ
YMS vs WMS vs TMS FAQ
What is the difference between a YMS and a WMS?
A yard management system (YMS) runs truck visits outside the warehouse — gate capture, yard map, dock assignment, dwell, and gate-out closeout. A warehouse management system (WMS) manages inventory and tasks inside the building. They complement each other; the YMS hands off dock-ready signals.
Can a WMS replace a yard management system?
For low-volume sites with minimal staging, a WMS yard tab may suffice. Gate-heavy yards with carrier self-service, live maps, and ERP closeout usually need a dedicated YMS layer that owns the full visit record.
How does a TMS fit with YMS and WMS?
Transportation management plans loads and carrier contracts. YMS executes arrivals on site — gate, yard, dock, and departure. WMS executes inside the building. All three share data but own different parts of the supply chain.
When should I add a YMS if I already have a WMS?
Add a YMS when gate teams maintain separate logs, dwell is discovered late, carriers call for status, or finance retypes gate-out into ERP. Those gaps mean the visit record is fragmented before it reaches the WMS.
