A carrier is a transport service provider that physically moves goods from a point of origin to a destination. It assumes operational responsibility for the actual transport – as opposed to freight forwarders or logistics service providers, who often only coordinate.
Key facts
- A carrier assumes physical responsibility for moving goods and bears operational responsibility for the transport.
- Carriers are differentiated by mode of transport: road, air, sea and rail.
- IT integration of carriers with WMS and shipping systems is typically achieved via APIs or EDI interfaces.
- In a multi-carrier approach, the carrier is selected dynamically for each shipment based on criteria such as region, size or transit time.
- SLA measurement and carrier performance monitoring are core tasks in transport management.
What is a carrier?
The term carrier refers to a company that physically provides transport services – that is, it moves goods, parcels or freight shipments using its own or chartered vehicles, aircraft, ships or trains. Unlike a freight forwarder, who typically acts as an organizer and contractual party, the carrier is the actual conveyor. In practice, however, these boundaries blur: many large logistics companies operate simultaneously as carriers and as freight forwarders.
Carriers can be differentiated by mode of transport: road carriers (general cargo, parcel, part-load and full-load), air carriers (air freight and express), sea carriers (container, bulk) and rail carriers. For intralogistics and last-mile delivery, parcel and general cargo carriers are particularly relevant, working in close integration with warehouse management and shipping systems.
How does carrier integration work in practice?
In modern logistics environments, warehouse management systems (WMS) and shipping solutions communicate directly with carriers' IT systems. Shipment registrations, tracking numbers, label printing and collection orders are exchanged in real time. Common interfaces include EDI connections, proprietary carrier APIs or standardized middleware solutions.
Key operational aspects include:
- Collection time windows and cut-off times that drive the shipping process in the warehouse
- Shipment tracking as the basis for proactive customer communication
- Labeling requirements per carrier and destination region
- Returns handling as a standalone carrier process
What matters when selecting a carrier?
Carrier selection should be based on a structured tendering process in which service commitments (Service Level Agreements, SLAs) and actual performance are assessed separately. Relevant criteria include delivery rates, transit times, damage rates, coverage of relevant regions and the quality of tracking data.
Many shippers rely on a multi-carrier approach: the most suitable carrier is selected dynamically depending on parcel size, destination region or service requirements. This increases flexibility but requires a capable shipping platform and clear rules for carrier selection. Whether a single-carrier or multi-carrier model makes more sense depends on shipment volume, geographic reach and negotiated terms – there is no universal answer here.
