What is the Difference Between 3PL and 4PL?

The main difference between a 3PL (3rd Party Logistics) and a 4PL (4th Party Logistics) lies in their scope of services and responsibilities:


  • Focuses on specific services: 3PLs typically handle particular tasks within the supply chain, such as warehousing, transportation, freight forwarding, or customs brokerage.
  • Acts as a contractor: They follow the client’s instructions and execute their assigned tasks.
  • Limited visibility and control: Clients have limited visibility into their supply chain and less control over individual processes.
  • Cost-effective option: 3PLs offer a cost-effective way to outsource specific logistics functions.
  • Suitable for: Companies of all sizes with specific needs in particular areas of their supply chains.


  • Manages the entire supply chain: 4PLs take a holistic approach, managing all aspects of the supply chain from sourcing and procurement to fulfilment.
  • Acts as a strategic partner: They collaborate with the client to develop and implement customized solutions, optimizing the entire supply chain for improved performance.
  • Full visibility and control: Clients have complete visibility into their supply chain and full control over decision-making.
  • High-level expertise and technology: 4PLs require expertise in various logistics disciplines and utilize advanced data analysis and optimization technology.
  • Increased cost but more excellent value: While more expensive than 3PLs, 4PLs offer significant value through improved efficiency, cost savings, and competitive advantage.
  • Suitable for Large companies with complex supply chains or those seeking comprehensive optimization and strategic partnership.

Here’s a table summarizing the key differences:
