In logistics, terms such as 1PL, 2PL, 3PL, 4PL and 5PL are used to describe how companies organise their supply chains. Each model represents a different level of outsourcing and collaboration. For organisations aiming to grow or professionalise their logistics, it is essential to understand which model aligns with their ambitions, volumes and complexity.
This page provides a clear overview of the differences and their practical implications.
Overview of logistics models
| Model | Characteristic | Control | Complexity |
| 1PL | All logistics handled internally | Full internal control | Low |
| 2PL | Transport outsourced | Shared control | Limited |
| 3PL | Multiple processes outsourced | Partner executes | Medium |
| 4PL | Integrated supply chain orchestration | External coordination | High |
| 5PL | Data-driven logistics networks | Strategic network control | Very high |
These models often represent a maturity path in logistics development. As organisations grow, their requirements for flexibility, cost control and service performance evolve.
What do the different logistics levels mean?
1PL – logistics fully managed in-house
Within a 1PL model, a company manages transport, warehousing and planning itself. This provides control but requires investments in people, systems and infrastructure.
2PL – transport outsourcing
In a 2PL setup, physical transport is handled by an external carrier, while the company remains responsible for inventory management and warehouse processes.
3PL – integrated logistics support
In a 3PL structure, activities such as warehousing, order fulfilment and transport coordination are consolidated with one logistics partner. This enables scalability and process optimisation.
4PL – central supply chain coordination
A 4PL provider focuses on supply chain optimisation, managing multiple providers and strategic logistics planning.
5PL – network-driven logistics
5PL involves digital integration and the bundling of logistics flows, often within large international networks.
Why companies move towards 3PL
For many organisations, the transition from 1PL or 2PL to 3PL marks a natural step in their development. As volumes increase and delivery expectations rise, managing logistics internally can become a constraint.
Working with a specialised partner can offer:
- flexible storage capacity during growth or peak periods
- greater predictability of logistics costs
- professionalisation of systems and processes
- improved delivery reliability for customers
As a result, logistics shifts from an operational burden to a strategic and scalable business function.

Organising logistics with growth in mind
Choosing the right logistics model means planning. By regularly evaluating whether your current setup supports your ambitions, you can prevent logistics from becoming a barrier to further development.
