3PL Warehousing & Logistics Guide | How It Works & Benefits

So you've been struggling with supply chain inefficiencies?


Managing inventory, order fulfilment, and shipping can be overwhelming, and that’s where a 3PL (Third-Party Logistics) provider comes in. Handling logistics through delegating a bulk of back-end processes allows you to focus on big-picture initiatives like expanding into new markets or launching new products. In today’s fast-paced world, it is imperative to do everything possible in order to streamline operations, cut costs, and improve efficiency to stay competitive.


So, whether you're an e-commerce entrepreneur, a manufacturer, or a global retailer, understanding how 3PL services work can help significantly improve your logistics strategy.

What is 3PL & Why Does It Matter?

When outsourcing, everything from inventory storage, order fulfilment, and transportation to distribution would be handled by a specialised provider. Whether it is during a geopolitical conflict, another pandemic or economic uncertainty, 3PL helps mitigate any negative effects. Furthermore, 3PL offers value-added services like customised packaging, handling any return issues, and improving supply chain efficiency.

In layman's terms, the key functions are,

  • Warehousing & Storage – Storing inventory in fulfilment centres or distribution hubs.
  • Inventory Management – Tracking stock levels, replenishment, and demand forecasting.
  • Order Fulfilment – Picking, packing, and shipping products efficiently.
  • Transportation & Freight Management – Coordinating shipping through carriers for domestic and international deliveries.
  • Reverse Logistics – Handling returns, exchanges, and disposal of unsellable goods.
  • Value-Added Services – Custom packaging, labelling, kitting, and product bundling.

How 3PL Works: Step-by-Step Process

Now that you know what it is, how exactly does it work in each stage? Below is an outline of the step-by-step breakdown of how third-party logistics work, from receiving inventory to handling returns.

1) Receiving Your Goods
The chosen 3PL company receives your products from your domestic or overseas supplier or your manufacturing facility. Upon arrival, the hired company inspects, sorts, and logs the inventory into its Warehouse Management System (WMS). When all products are accounted for and it’s made sure to be up to stringent quality control standards, the next step is to make sure inventory levels are updated in real time. This allows businesses to track stock remotely and ensure seamless order fulfilment to keep your customers happy!

2) Managing your Inventory
The 3PL warehouse then takes those goods and strategically places them in the most efficient manner for quick-paced picking and packing according to its Warehouse Management Guide. Advanced inventory tracking systems can help monitor stock levels, preventing stockouts or overstocking, and making sure your customers get their goods as fast as possible! Some 3PL providers can also leverage automated demand forecasting, analysing sales trends to recommend optimal stock replenishment and help avoid unnecessary storage costs.

3) Fulfilling the order
3PL uses software integration to connect with your online platform or marketplace. So when an order is placed 3PL’s warehouse team can then retrieve the items from storage. The product is then packaged in the most suitable material to ensure product safety and minimal costs to the company. 3PL can also add customised labelling or branding to further promote your business!

4) Shipping to your happy customers
3PL then ships the orders through a selected carrier, such as FedEx, UPS, DHL, or a regional courier. The system then generates a tracking number, which updates in an inventory management system allowing tracking by you or your customers. The product will then be shipped depending on your policies or selected shipping options!

5) Returns
For whatever case in the possibility of a return the 3PL manages the reverse logistics process. Returns are inspected to determine whether the items can be restocked, refurbished, or discarded based on predefined criteria set by your business. By streamlining returns, 3PL providers help your losses to a minimum, maintain inventory accuracy, and keep your customers happy!

Location, Location, Location!

Whether you’re launching a new product, expanding into new markets, or dealing with seasonal spikes in demand, your 3PL should be able to offer you a diverse range of options ranging from flexible storage, and shipping, to fulfillment.

Avoid Unnecessary Costs
Every 3PL has different pricing models, which may include charges for storage, picking, packing, and shipping.

Pricing structures should be compared to ensure that the 3PL offers cost-effective solutions that align best with your budget.
