01 / The short answer
Who runs the logistics?
Who coordinates the network?
The labels 1PL, 2PL, 3PL and 4PL describe different ways of assigning logistics responsibilities between the cargo owner, transport providers and coordination partners. They are useful shortcuts — but scope is ultimately defined by contracts, operating processes and data ownership.
Buy defined capacity
A specialist provider supplies a transport or other specific logistics service, commonly with its own assets.
Outsource logistics execution
A partner manages a wider logistics scope such as transport coordination, warehousing or fulfilment, as agreed.
Orchestrate the network
An integrator coordinates multiple service providers, visibility, processes and performance at network level.
Not the same as primary versus secondary
A movement from a refinery to a depot may be primary logistics and be performed by an internal fleet, a 2PL carrier or a 3PL service provider. The flow classification and the service model describe different dimensions.

1PL — logistics operated in-house
A business organizes and performs logistics with its own teams and assets. It retains planning and execution control.
Shipper
Own resources
Delivery
Internal fleet · Internal operating rules · Internal accountability
A company may still purchase some external services; classifications are simplified descriptions.
2PL — specialized capacity provider
A transport provider supplies a defined service, typically physical carriage. The shipper or another coordinator integrates that service into the overall operation.
Shipper
External carrier
Delivery
Capacity contract · Pickup and delivery requirements · Carrier updates
A carrier can be a 2PL provider within an operation managed by a 3PL or 4PL.
3PL — managed logistics services
A 3PL coordinates a broader outsourced logistics scope, potentially combining transport planning, execution, warehousing or fulfilment depending on the contract.
Shipper
Logistics provider
Carrier network
Multi-client workflows · Carrier selection · Service commitments
3PL scope is contractual: not every 3PL performs warehousing or owns trucks.
4PL — network-level orchestration
A 4PL-style arrangement focuses on coordinating several logistics providers and the end-to-end operating model, with visibility, governance and performance management.
Shipper
Lead integrator
Multiple providers
Multi-provider accountability · Performance model · Data integration
1PL–4PL are common business labels, not rigid universal standards.
Do not assume a linear maturity ladder
1PL is not automatically immature and 4PL is not necessarily the preferred end state. A large enterprise may deliberately operate a critical in-house fleet while outsourcing other regions to several providers. The right model depends on service risk, asset economics, regional coverage, available expertise and the desired degree of control.
03 / Role and responsibility
Compare what is delegated.
| Model | Typical outsourced role | Who coordinates the operation? | Important TMS questions |
|---|---|---|---|
| 1PL | Minimal or selected services | Shipper's own operation | Vehicles, orders, drivers, internal planning |
| 2PL | Defined transport capacity or service | Shipper or another lead party | Carrier bookings, availability, tracking events |
| 3PL | Broader logistics execution and coordination | Contracted logistics provider within its scope | Multi-client visibility, allocation, billing, SLAs |
| 4PL | Network orchestration / lead logistics management | Integrator across several providers | Common data model, integration, oversight, governance |
These descriptions reflect common commercial practice; the labels are not precise legal categories or universal requirements. A 3PL may focus primarily on transportation, and an asset-owning logistics company may also provide higher-level coordination services.
Three contract questions that matter more than the label
- Who accepts the order? Identify the entity responsible for taking a transport requirement and turning it into an executable plan.
- Who makes exceptions decisions? Define who can reassign a carrier, approve a route change or resolve an incomplete delivery.
- Who owns the operational truth? Confirm source systems, milestones, invoicing data, and the authority to approve changes.
04 / Transport technology
Where does a TMS fit?
Transportation management is relevant across all four models. The difference is not whether a TMS is needed, but which parties use it, what information they can see, and which decisions they may take.
One operational view
Compare transport requirements with internal capacity and carrier resources, then assign and track the chosen execution model.
Different rules, same platform
A logistics provider may need client-specific rates, planning constraints, access rights and reporting within shared operations.
Relevant iBisTMS areas include Carrier Management, Route Scheduling, Freight Settlement and Enterprise Integration. The operating model should shape configuration and governance; terminology alone does not determine the design.
05 / Frequent questions
Common questions.
Does a 3PL need to own trucks or warehouses?
No. The service scope and coordination responsibility are more important than asset ownership. Some providers rely heavily on subcontracted assets.
Can one company use 1PL, 2PL and 3PL at once?
Yes. A shipper may operate an internal fleet in one region, buy carrier services for another and delegate some distribution processes to a 3PL.
Does 4PL always replace 3PL?
No. A 4PL-style lead integrator can coordinate several 3PLs and carriers. The models can coexist.
Is 3PL the same as secondary logistics?
No. 3PL describes a service provider's role. Secondary logistics describes a type of physical transport flow within a given network.
For further context, see the explanatory guides published by Kuehne+Nagel, DHL and Maersk. Final responsibilities always follow actual service contracts.
