Third Party Logistics

As a business owner, choosing your logistics partner is a crucial aspect of becoming a successful business. As companies grow and their consumer base increases, they have to consider outsourcing their fulfillment services. There are two types of fulfillment services:

  • 3PL – Third Party Logistics services
  • 4PL – Fourth Party Logistics services

Both service providers have their own features, benefits and tradeoffs. Below is a detailed discussion which will enable you to determine the logistics partner that fits your operational needs.

What is 3PL?

A third party logistics provider (3PL) is a company that provides outsourced logistics services. They perform various operational functions which include: warehousing, inventory management, packaging, and transportation. Many businesses choose to rely on 3PL to expand their business, save costs, and enhance customer satisfaction. Business owners can focus on scaling their business and enhancing their core competencies while leaving logistics operations to the experts. 

What is 4PL?

A fourth party logistics provider (4PL) is a company that oversees your entire supply chain operations acting as a strategic supply chain integrator.  They do not only overlook operational logistics functions but they also develop key strategies to optimize the supply chain. 4PL companies coordinate and manage multiple 3PL providers allowing a business to fully focus on its growth and consumer base.

3PL vs. 4PL: Key Differences

Third Party Logistics

Fourth Party Logistics

Primary Focus and Scope

  • 3PL services providers offer storage, inventory management, order fulfillment and transportation services. 
  • They handle day to day logistics operations and act as intermediaries ensuring efficient movement of goods through the supply chain.
  • 4PL providers manage the entire supply, integrating multiple 3PLs while focusing on strategic oversight and optimization. 
  • Unlike 3PL providers which act like intermediaries, 4PL providers act as leaders of all supply chain operations.

Extent of Control

  • Businesses which utilize 3PL services outsource logistics operations while retaining direct control over planning. They can choose specific logistics services and tailor them as needed. 
  • If a business has multiple 3PL providers, then it is responsible for managing them all.
  • 4PL providers take full control of a business’s supply chain. They act as a control tower for all the logistics operations coordinating and integrating every individual and every function within the chain. 
  • Business owners are not directly involved in the supply chain; thus, they can focus on other important business functions.

Use of Technology

  • 3PL providers use technologies such as warehouse management systems and transportation management systems.
  • In short, they provide tools and technology limited to the services they provide. 
  • 4PL providers utilize advanced technology – AI, IoT, real time tracking and predictive analytics to optimize supply chain operations. 
  • They can collect data from all points within the supply chain.

Cost and Affordability

  • 3PL services are generally more affordable than 4PL service providers. 
  • They are best suited for small to medium sized businesses which do not have the ability to build an entire infrastructure from scratch.
  • 4PL services are more costly and provide greater value than 3PL services. 
  • They are best suited for large firms which have complex supply chain operations and need a single leader to handle all logistics providers within the supply chain.

Suitability – which suits your business better?

If you are a small or medium sized business with simple and straight forward operations then 3PL services are best suited for your business. Moreover, if you want to outsource logistics solutions but retain key strategizing functions then go for a 3PL service provider.

On the other hand, 4PL services are ideal for large businesses with multiple logistics providers in a supply chain. They are best suited for businesses who want to outsource all supply chain solutions so that they can focus on expanding their business and improving customer experience.

To sum it up, businesses wanting to outsource logistics functions should take into account their business size, operational scope and budget before choosing a logistics provider. A 3PL provider can enable small to medium sized businesses to improve logistics operations while also maintaining cost efficiency. On the other hand, a 4PL provider can enable large businesses to fully focus on expanding their business by leaving all supply chain management to the experts.
