Fourth Party Logistics (4PL) in Supply Chain

Organizations aim to manage their operations more effectively along the supply chain. In today's complex commercial environment, full of various potential risks and disruptions due to the variability of target audience expectations or the functioning of the supply chain, it is extremely important to maintain an efficient supply chain management. Fourth Party Logistics (4PL), a concept born out of this need, is an effective solution that enables supply management issues, including the logistics process, to be managed with effective, efficient integrated solutions in the long term. We have compiled the subject for you in various aspects.

Differences between 1PL, 2PL, 3PL, 4PL

In the 1PL supply chain model, the manufacturer produces the goods in-house and performs some or all of the logistics in-house. In the 2PL model, unlike the 1PL, there is a distributor, which supplies the manufactured goods and performs some or all of the logistics in-house. In the 2PL model, the asset owner who owns the means of transportation is a carrier, in other words, distribution comes into play. For example, there are shipping lines that own, lease or rent transport vessels; airlines that own, lease or rent transport aircraft; carriers that own trucking companies or fleets or lease or rent their trucks.

In the 3PL model, which emerged in the 1970s, the logistics service provider performs all logistics processes on behalf of distributors and manufacturers. A 3PL provider is a company that merely receives, holds or otherwise transports products to be delivered to the consumer in the ordinary course of business, but does not take ownership of the product. Preferably, these services are bundled together by the provider, which offers many services (cargo transportation, warehousing, cross docking, inventory management, picking and packing, kitting, light assembly, packaging, labeling and shipping, and other value-added services). While a 3PL provider focuses solely on logistics, an advanced 4PL provider differs in that it focuses on providing full visibility of its type throughout the supply chain. In other words, a 4PL organization enables the management of all aspects of a customer's supply chain as a “single interface”, bringing standardization between the customer and multiple logistics service providers.

A 4PL provider can be defined as a separate entity established as a joint venture or long-term contract between primary customers and other logistics companies, based on definitions set by the Council of Supply Chain Management Professionals. Models may vary according to business needs and how deeply the business needs to outsource in order to focus on its core business, a hybrid model can be created and a combination of multiple alternatives can be used.

What is Fourth Party Logistics (4PL)?

The concept of Fourth Party Logistics, abbreviated as 4PL, refers to an approach or strategy within the supply chain where the operations are managed by an independent service provider. Expert businesses in this field analyze the needs of their clients, create strategic plans, and develop integrated solutions. In other words, 4PL involves an external firm or consultant organizing, planning, managing, and optimizing the supply chain processes of an organization. A 4PL provider is defined as a supply chain intermediary that combines and manages its resources and technologies with those of complementary service providers to offer a comprehensive supply chain management solution. Thus, it is an actor within the supply chain. 4PL providers are often referred to as non-asset service providers or Lead Logistics Providers (LLP). Their roles within the supply chain are extensive, creating a broader scope to manage the entire supply chain, which leads to standardization.

Advantages of the 4PL Model in the Supply Chain

The 4PL model offers numerous advantages for organizations with large and complex supply chains, improving the flow of the supply chain. This service can help customers gain a competitive edge, reduce costs, and better manage supply chain processes. Therefore, it contributes to the development and improvement of organizations' supply chain strategies.

A 4PL logistics provider is also a supply chain partner. It offers professional support by providing comprehensive planning and execution of all shipments throughout the value chain in external shipping and logistics processes. When multiple businesses involved in a particular supply chain manage their logistics systems independently from each other, different standards emerge, leading to various workflow standards throughout the chain. Integrated logistics is strategized to solve the problems arising from these differences.

Integrated logistics, which expands the 4PL model to include customers, suppliers, and manufacturers, ensures the continuous monitoring, measurement, and optimization of the supply chain's performance through reports. Therefore, 4PL logistics providers manage critical operational processes like logistics professionally with integrated solutions and functional and flexible management, especially during crisis periods.

In the 4PL model, the focus is on technology solutions to digitize end-to-end processes and develop various data-driven logistics ecosystems. This significantly facilitates the flow of the supply chain. Since it acts as the single point of contact and access for all transportation activities managed throughout the supply chain, optimization is easier, and the flow of logistics operations is simplified. Providing end-to-end visibility and data access on a single platform ensures better protection, minimizing risk assurance through a single connected platform. Increased levels of collaboration and integration enable agile planning and execution, which is crucial in today’s increasingly complex logistics environments, creating significant advantages.

The 4PL model, when strategically managed and tailored to the specific needs of an organization, provides proactive support in crisis communication by ensuring the necessary measures are taken and managed. 4PL providers take all necessary steps to manage the client's supply chain operations, including material procurement, production, storage, transportation, inventory management, and distribution. Since 4PL firms operate independently, they can make more objective and efficient decisions with the responsibility of protecting the clients' interests. By utilizing data analytics, automation, and other technologies, they monitor and improve supply chain processes, resulting in better efficiency and visibility.

4PL Model and Customer Satisfaction

Deciding which supply chain model is most suitable for a specific business should be considered in the context of that business’s needs. Therefore, the supply chain model should be evaluated not only as a method but also as a strategy. A 4PL provider traditionally operates a system of outsourced supply chain services, using customized strategies, tools, and technologies to enhance logistics efficiency, thereby enabling clients to experience a smoother and more cost-effective shipment cycle. This plays a crucial role in ensuring and maintaining customer satisfaction.

By selecting the most appropriate suppliers and establishing effective relationships with them, 4PL providers enhance supplier communication. This positively contributes to managing the client's good relationships and reducing costs related to material procurement.

According to research firm Gartner, 4PL service providers are securing an increasingly strong position in today’s complex logistics environment, which is fraught with risks and disruptions. The role of 4PL in the supply chain is not limited to logistics but also includes supply chain planning, inventory management, demand management, and procurement management capabilities. As 4PL evolves, it transitions into the 5PL model. Given the global agenda focusing on the climate crisis and related issues, the primary focus of the 5PL model is to ensure the best possible solution with minimum cost or carbon footprint. Accordingly, the 5PL model relies on B2B collaboration and a higher degree of resource utilization to create opportunities. The core aim is less cost and lower carbon emissions. Based on the global agenda, we will see the development of the 5PL model and even new models surpassing these developments in the coming years.
