Fulfilment and logistics companies are often labelled as 1PL, 2PL, 3PL, 4PL or 5PL but what does that mean? And how do these stamps differ? These stamps indicate the extent to which companies can take over your logistics operations: from keeping all logistics activities in-house to leaving the entire supply chain management to external parties, and all options in between.

The term 1PL refers to a situation where an organisation stores its goods itself and transports them to the end customer, without using external logistics service providers. Small manufacturing companies with local distribution are typical examples of 1PL operations. They are completely self-sufficient in their logistics processes and carry out all activities internally.

2PL refers to the first step of outsourcing logistics tasks, including transport and storage. Companies offering 2PL services act as logistics operators and are responsible for both transport and storage of goods.

In 3PL, a large part or even the entire logistics process of a company is outsourced to an external logistics operator. This operator acts as an intermediary between the client and its customers, organising transport and storage facilities. It covers a wide range of fulfilment services, such as inventory management, order processing and return logistics.

A 3PL fulfilment partner goes far beyond simply arranging storage and transport. They ensure that your entire order flow runs smoothly and without errors, from the first incoming pallet to the moment of delivery to your customer. Concretely, this includes services such as inbound processing (receiving, counting, quality control), smart put‑away and stock allocation, so your inventory is always reliable.

The partner then takes care of the complete order processing: importing orders via integrations, picking per item or in batches, packing according to your brand guidelines and adding documents, promotional material or personalised inserts. Creating shipping labels, selecting the right carrier and providing track‑and‑trace are also part of the service. Finally, the 3PL provider also handles returns: they inspect the goods, book them back into stock or write them off, and provide reporting so you can see exactly what is happening.

You mainly choose 3PL logistics when you notice that your internal organisation can no longer comfortably handle the demand. Typical signs are: a warehouse that is structurally too full, peak days on which your team can no longer keep up with the work, or incorrect deliveries because processes have become too ad hoc. The moment you start shipping to multiple countries or combine different sales channels, things also become complex internally very quickly.

In these situations, a 3PL partner helps you regain control: you make use of professional processes, systems and capacity without having to make major investments yourself. This allows you to focus on growth, while your fulfilment becomes more scalable, predictable and easier to measure.

4PL includes supply chain management services such as consulting, planning and supply chain optimisation. Unlike 3PL organisations, 4PL entities do not perform physical transportation or fulfilment activities. However, they manage the client’s end-2-end supply chain and initiate supply chain design and optimisation.

Unlike 3PL organisations, 4PL entities do not perform physical transportation or fulfilment activities. However, they manage the client’s end-2-end supply chain and initiate supply chain design and optimisation.

4PL is particularly interesting for companies with multiple warehouses, international flows or a mix of B2B and e‑commerce streams. Think of organisations that work with several carriers, suppliers and fulfilment partners and find it difficult to turn that into one coherent whole.

Fast‑growing companies that see their logistical complexity increasing, but do not want to build a large internal logistics team, also benefit from a 4PL model. They look for a strategic partner who keeps the overview, supports decisions with data and continuously searches for cost savings and service improvements.

5PL is a relatively new term that refers to an advanced level of logistics management. A 5PL operator combines the execution of transport and fulfilment activities of a 3PL provider with the supply chain optimisation of a 4PL provider. They manage not only the supply chain, but also a network of supply chains for the client, with a focus on using advanced (new) technologies.

In a world where efficiency and optimisation make the difference, 1PL to 5PL players play an important role. They shape logistics strategies and support business growth by, for example:

In an era of increasing globalisation and complexity, choosing the right level of outsourcing is essential for efficiently managing logistics processes. Whether it is to maximise operational efficiency, reduce costs or optimise the supply chain, finding the right balance between in-house management and outsourcing can be the key to success in a competitive market.
