What is 3PL Fulfillment?

Third-party logistics (3PL) fulfillment involves outsourcing your supply chain functions to an external provider. This provider will offer comprehensive fulfillment services, including warehousing, inventory management, order processing, and shipping.

3PL fulfillment has been a game changer for eCommerce businesses. With a 3PL provider, you can handle large volumes of orders efficiently and easily improve your delivery times. This outsourcing solution also helps you save on costs associated with storage and shipping.

In this guide, we explain what is 3PL fulfillment, the services that 3PL providers offer, and how you can choose the right provider.

What are Third-party Logistics (3PL) Providers?

3PL providers are companies that will handle the storage, management, and fulfillment of your orders. They allow you to outsource various aspects of your supply chain operations, including warehousing, order processing, shipping, and returns management. 3PL providers are experts in eCommerce fulfillment, providing tailored solutions to meet your specific needs.

Services Offered by 3PL Fulfillment Centers

A 3PL eCommerce fulfillment center will offer a wide range of services to ensure the right products reach the right customers efficiently. Here's an overview of the services you can expect when you partner with a 3PL provider:


Warehousing in fulfillment involves temporarily storing goods in the facility until they are ready to be shipped to customers. When you partner with a 3PL provider, you will send your products to the 3PL center. On arrival, they will go through a systematic receiving process.

In the receiving process, the 3PL center will inspect your products for quality and accuracy. They will then log each item into their inventory management system, ensuring accurate stock levels. Your products are then stored in designated areas within the warehouse, ready to be picked and packed when orders come in.

Order Processing

Order processing is the series of steps taken to fulfill a customer’s order. When an order is received, the 3PL logistics company system will generate a picking list, which warehouse staff use to locate and retrieve the ordered items from storage.

The picked items are taken to a packing station where they are carefully packed to ensure they arrive safely. The 3PL provider's team will use appropriate packaging materials to protect the products and match your branding requirements. The packed orders are then labeled with shipping information and prepared for dispatch, ready to be sent out to your customers.

Inventory Management

Inventory management is an important service as it ensures that you always have the right products available to meet customer demand. Effective inventory management prevents stockouts and overstock situations, which can both negatively impact your business. By maintaining optimal inventory levels, the 3PL provider can help you reduce storage costs and improve customer satisfaction.

3PL providers offer this service by using advanced inventory management software. This software provides real-time visibility into your stock levels, helping you track inventory accurately. 3PL providers will also conduct regular inventory audits and cycle counts to ensure the accuracy of their records and the availability of your products.

Shipping and Logistics

Shipping and logistics involve transporting products from the warehouse to your customer's doorstep. Partnering with a 3PL provider offers the advantage of better shipping rates. This is because 3PL providers have established relationships with major carriers, ensuring you get competitive rates and reliable delivery options.

If you have an international customer base, a 3PL provider can simplify the complexities of global shipping. They handle customs clearance, documentation, and compliance with international regulations. This expertise ensures your products reach customers worldwide efficiently and without delays.

Returns Management

Returns management is the process of handling product returns from customers. A 3PL provider manages the entire returns process, from receiving returned items to restocking or disposing of them. This service ensures a smooth and efficient returns experience for your customers, which can enhance customer satisfaction and loyalty.

Technology Integration

Technology integration involves using software and systems to streamline logistics operations. One key offer is multi-channel integration for order processing. This ensures that no matter where your customers place their orders, they are processed seamlessly and efficiently.

3PL providers offer technology solutions that also integrate with your existing eCommerce platforms. This integration provides real-time visibility into inventory levels, order status, and shipping updates. It also provides valuable insights into your supply chain, helping you make informed decisions to optimize your operations.

Why Partner with a 3PL Fulfillment Provider?

Whether you run a B2B or B2C business, partnering with a 3PL fulfillment provider can improve your operations. They do this by handling all your order fulfillment tasks, from receiving orders to handling returns. This partnership streamlines your processes, helping you reduce operational costs while still ensuring timely deliveries to your customers.

3PL fulfillment providers are also a strategic partnership for businesses of all sizes. For startups and SMEs, they offer access to advanced logistics technology and scalable infrastructure without costly investment. For large businesses, they provide the flexibility and efficiency needed to manage high order volumes and international shipping seamlessly.

How To Choose the Best 3PL Provider

Choosing the right 3PL provider is crucial for optimizing your logistics and supply chain operations. When evaluating potential partners, consider their service offerings, cost structure, and scalability.

Service Offerings

To enjoy the full benefits of a 3PL fulfillment partnership, ensure the provider you choose offers comprehensive services. They should provide everything from warehousing to returns management to meet your business needs. This way, you can focus on your business, knowing that your order fulfillment is fully covered.

Cost Structure

The 3PL provider’s cost factor is an important consideration factor. Make sure that the provider offers transparent pricing that covers all fees involved, including storage, shipping, and additional service charges. You can then compare the different provider costs to find one that works within your budget.


It’s essential to consider your business’s future when choosing a 3PL provider. You need to ensure that the provider can accommodate your current order demand, as well as your forecasted demand or any expected seasonal spikes. A scalable 3PL partner will support your long-term expansion plans and adapt to changing market demands, ensuring seamless operations as your business grows.

3PL vs 4PL: What’s the Difference?

When planning to outsource your eCommerce fulfillment, you may also be considering a 4PL provider. A 4PL provider manages the entire supply chain, including overseeing 3PL providers. They act as a single point of contact for all logistics operations.

You might choose a 4PL provider if your business requires comprehensive supply chain management. This is especially beneficial if you have complex logistics needs or operate on a global scale. A 4PL provider can streamline and optimize every aspect of your supply chain, allowing you to focus entirely on your core business activities.
