When it comes to logistics and supply chain management, businesses often rely on third-party logistics (3PL) and fourth-party logistics (4PL) providers to help scale and streamline their operations. While both offer similar services, there are some key differences between the two that are important to understand. In this article, we will take a closer look at 3PLs and 4PLs to help you determine what’s right for your business.

What is a 3PL?

A third-party logistics provider, or 3PL, is a company that provides outsourced logistics services to businesses. These services can include transportation, warehousing, order fulfillment, inventory management, and more. Essentially, 3PLs take care of the logistics tasks that a business would normally handle in-house. This allows businesses to focus on their core competencies while leaving the logistics to the experts.

What is a 4PL?

A fourth-party logistics provider, or 4PL, has pre-established relationships with network of 3PL operators with integrated technology to provide visibility into inventory, orders, and operations within a single technology platform. A 4PL provider also has enhanced integration capabilities to seamlessly connect and automate inventory and order data into your existing systems such as an ERP.

Comparison between 3PL and 4PL

Scope of services and capabilities

The biggest difference between a 3PL and 4PL is the scope of services offered. A third-party logistics (3PLs) provider typically provide specific logistics services, such as transportation or warehousing. In contrast, a 4PL provides manages your network of 3PL warehouses, overseeing everything from sourcing to integrations and execution.


A 3PL operates on behalf of a company, but the company retains control over its own supply chain. The 3PL is responsible for executing logistics tasks but does not have the final say in decision-making. A 4PL, on the other hand, helps provide business advisory and decision support to guide a company’s logistics operations.


A 4PL provides more flexible than a 3PL. With fixed assets like warehouses, they can’t easily adjust their operations to meet the needs of their clients. 4PL warehouse providers, like WarehouseQuote, provide businesses with flexibility to add or move warehouse locations based on shifts in their warehousing and fulfillment strategy.


Both 3PLs and 4PLs rely heavily on technology to manage logistics operations. However, 4PLs typically have more advanced technology platform including integrations with ERP’s, ecommerce platforms, retail partners, and marketplaces. This makes it easier for 4PLs to manage complex warehousing and fulfillment networks.


Because 4PLs provide a broader range of services, they are typically more expensive than 3PLs. However, many businesses find that the benefits of warehousing and fulfillment network management are worth the additional cost.

In conclusion, while both 3PLs and 4PLs provide valuable logistics services to businesses, they differ in their scope of services, level of control, flexibility, technology, and cost. Ultimately, the decision of which provider to use will depend on the specific needs of the business and the level of logistics expertise required.
