The Ultimate Guide To Third-Party Logistics (3PLs) And How They Handle Order Fulfillment


A significant portion of a business’s day-to-day operations involves fulfilling customer orders. The order fulfillment process begins when the customer places an order and ends when it arrives at their doorstep.

What seems like a simple process can become quite complex depending on the storage location of your company’s inventory, the customer’s location, the size of the order, and the timetable for delivery. It becomes even. more complicated when you factorl for returns.

When a business grows beyond its capability to manage order fulfillment in-house, it might be time to consider outsourcing certain functions to third-party logistics companies (aka 3PL services).

Keep reading to learn everything you need to know about 3PLs.

What is a 3PL?

Third-party logistics involves three parties – the business, the logistics provider, and the shipping carrier. In simple terms, a third-party logistics provider offers logistics services to manage certain aspects of a company’s shipping operations. 3PLs are renowned for their logistics industry expertise and can help companies better fulfill orders to keep their customers happy.

In most cases, a 3PL becomes integrated into the company’s inventory storage and transportation procedures. Rather than storing, packaging, and shipping orders themselves, companies hire a 3PL to manage the entire process. The 3PL owns or leases its storage and transportation assets, using them to fulfill the client’s orders from a remote location. By handing over management of order fulfillment logistics to a third-party provider, companies can focus more on growing and developing their business.

The third-party supply chain model was developed in the 1970s when intermodal marketing companies began receiving packaged loads from shippers and handled those loads to railroads for delivery. In the decades since, the process has become refined and modernized with 3PL software that simplifies and streamlines the whole process for 3PLs and the companies that hire them. 3PLs are used by businesses of all sizes ranging from Fortune 500 companies to startups.

What Services Does a 3PL Provide?

A 3PL can scale and customize its services according to the client’s specific needs, and the client still retains some degree of oversight when it comes to managing shipping operations. Before signing a contract, you can outline what services you want the 3PL to provide and what services you will retain in-house. As your business grows and changes, your 3PL provider can take on a more significant role by adding additional services or by expanding operations as a whole.

Here’s an overview of services a 3PL typically provides:

Warehouse Storage

Hiring a 3PL saves you from having to find storage space for all of your inventory. Many 3PLs offer shared storage, managing order fulfillment for multiple clients out of one physical location to maximize efficiency and keep costs down.

Inventory Management

Managing inventory involves more than simply storing your company’s products. It also involves integrative technology that syncs your inventory with your online store in real-time, so you can track inventory and predict demand to avoid sell-outs.

Inventory Distribution

Many 3PL providers manage multiple warehouse locations so your company’s inventory can be distributed across several fulfillment centers for fast shipment to different parts of the country. With the right technology, a 3PL can automate the fulfillment process, automatically routing orders to the best fulfillment center. 3PLs make extensive use of automation like this to make inventory distribution profitable for their clients.

Picking and Packing

In addition to storing your company’s inventory, a 3PL provider has staff in place to perform the specific tasks associated with order fulfillment, including picking the products in each order and packaging them appropriately for shipping.

Freight Forwarding

Once the products are picked and packaged, the 3PL forwards them to a shipping carrier for delivery. Different 3PLs work with other carriers, and a good 3PL will choose the one that offers the best combination of price and delivery speed. Some 3PLs even work with local carriers for less than truckload (LTL) shipping for local orders.

Expedited Shipping

Working with a 3PL enables your company to offer expedited shipping options to your customers because fulfillment centers send out orders daily – much more frequently than you would be able to provide if you handled orders in-house. 3PLs often have discounts negotiated with carriers like FedEx, DHL, USPS, and others to offer faster delivery speeds at a manageable cost.

Shipment Tracing/Tracking

In addition to handling the shipping process, a 3PL will also manage the tracing and tracking process. Customers will receive shipping information, so they can easily track their order throughout the order fulfillment process.

Reverse Logistics (Returns)

Not only do 3PLs offer shipment services, but they can also provide reverse logistics to handle returns. A 3PL can provide customers with return labels to drop the item off with a carrier for return to the fulfillment center.

Again, when you sign a contract with a 3PL company, you can customize its services according to your business’s needs. An experienced 3PL provider will be able to handle the logistics of the entire supply chain from the moment your customer submits their order to the moment it arrives on their doorstep.

How 3PLs Handle Order Fulfillment

To help you understand what this looks like, here is an outline of the order fulfillment process from a third-party logistics provider’s perspective:

Step 1: Receiving A 3PL can’t fulfill customer orders if they don’t have inventory, so the first step in the process is moving your inventory to the 3PL’s warehouse. Depending on your business’s size, your inventory may be divided among several fulfillment centers, so orders can be fulfilled more quickly and efficiently. Each 3PL has its own process for receiving and storing inventory, and most providers are able to customize this service according to the client’s needs.

Step 2: Picking

After a customer places an order, the next step is for the 3PL to begin fulfilling the order by “picking” the item. Depending on the type of integrative technology the 3PL offers, this information can be automatically sent to the 3PL or you might have to upload orders to their system manually. When the order is received, the 3PL’s picking team collects the item then passes it to the next stage of the supply chain for packaging.

Step 3: Packing

Once all items in an order have been picked, they are packaged for shipping.

Depending what options for customization your 3PL offers, you may be able to choose the packaging for your orders. Otherwise, standard packaging materials typically include unbranded boxes, bubble mailers, poly bags, packing tape, and bubble wrap. Some 3PLs will charge for packing materials while others include them in their fulfillment services. A good 3PL will choose the best materials to protect the product while achieving the lowest practical dimensional weight to keep shipping costs down.

Step 4: Shipping

After the order is picked and packaged, it is forwarded to a shipping carrier.

Some 3PLs have a preferred shipping carrier, while others compare costs to choose the best combination of price and delivery speed. In most cases, shipping carriers pick up orders from the 3PL’s warehouses.

Step 5: Returns

Not all orders end when the shipment hits the customer’s doorstep. Returns

are a significant concern for many businesses, and they can get messy if you’re managing a large stock of inventory on your own. When you hand over this aspect of the supply chain to a 3PL provider, all returns are directed back to the 3PL, where they are processed, restocked, or disposed of according to your company’s policy. You can even choose to have your 3PL provider provide shipping labels for your customers to streamline the process and enable them to track their return status.

By now, the benefits of a third-party logistics partnership should be obvious, but how do you know whether your company can benefit from such a partnership? Keep reading to learn the signs that it’s time to hire a 3PL.

When Do You Need a 3PL?

Unless you’re running a small retail business out of your garage with no more than a dozen orders a week, the chances are good that your company could benefit from hiring a third-party logistics provider. To help you decide, here is an overview of the benefits associated with working with a third-party logistics provider:

  • It will save you time: By outsourcing your company’s logistics, you will have more time to focus on the things it takes to grow and expand your business.
  • It could provide cost savings: A 3PL can package warehousing, shipping, and inventory management all for one price, and it could be lower than doing it all in-house.
  • It puts the burden in someone else’s hands: Handing over your company’s logistics to someone else can be nerve-wracking, but it means that someone else will be accountable.
  • It helps your business stay up-to-date with technology and regulations: A good 3PL stays up-to-date with the latest technology and industry regulations, which means you don’t have to.
  • Orders will be shipped correctly and efficiently: A 3PL exists to offer the best services at the greatest value – that’s how they get and retain customers, and that value is passed on to you.
  • It can be customized to your needs: When it comes to warehousing, shipping, and distribution, a 3PL provider can customize its services according to your needs and can adjust as you grow.
  • 3PLs give you access to better resources: Hiring a 3PL gives you access to the best inventory management software and other integrative technology that you might not get on your own.
  • 3PLs expand your reach: A 3PL provider has a network of partners, including shipping carriers and other providers, to ensure that you get the best services at the lowest rate possible.
  • 3PLs reduce your risks By outsourcing your company’s operational logistics, you don’t have to worry about things like labor risk and the financial risk of investing in equipment and storage facilities.

Still not sure whether hiring a 3PL provider is the next logical step for your business? Here are some of the top signs that your business could benefit from hiring a third-party logistics provider:

You’re shipping more than 100 orders per month

There is nothing magical about the number “100” – the point is that your company is receiving more orders than you can efficiently manage in-house. As your company grows and your inventory increases, you’ll find yourself spending more time and energy fulfilling orders than actually focusing on your business – that’s when you know it is time to hire a 3PL.

You’ve run out of storage space for your inventory. Any retail company’s goal is to have enough orders that it becomes necessary to expand your inventory. Of course, when this happens, you’ll need space to store all of that extra inventory. Rather than dealing with this predicament each time you add a new product to your store, turn over storage logistics to a 3PL.

You want to offer your customers expedited shipping

Suppose you’re currently managing your order fulfillment in-house. In that case, you may be struggling to make it to the post office even once a day, let alone often enough to give your customers expedited shipping options. With a 3PL handling your order fulfillment logistics, you’ll suddenly be able to offer one-day, two-day, and maybe even same-day delivery.

You want to save money on storage and shipping

Hiring a 3PL provider is by no means cheap, but it could save you a lot of time and money if done correctly. If you find yourself wondering whether it is worth spending the capital to lease warehouse space, consider hiring a 3PL instead and put that capital to better use expanding your business. As a critical component of the customer experience, fast delivery speeds provided by 3PL service providers can be a competitive advantage.

You want your company to have room to grow

The hallmark of any good businessman is forward-thinking. From the moment you start your business, you should have some idea where you want to go and how you want to get there. If you’re going to expand your offerings throughout the country or internationally, a 3PL can help you get there with inventory distribution services. For example, some 3PLs offer the ability to leverage 2-day or overnight shipping to help ecommerce businesses keep up with Amazon and other giants.

Hiring a 3PL provider to manage your supply chain’s logistics is a smart move if any or all of the signs above are coming into play. Before you start shopping around for a 3PL, however, you should take a moment to consider whether doing so is enough. You may want to think about taking things one step further and hiring a fourth-party logistics provider – keep reading to learn more.

What’s the Difference Between a 3PL and 4PL?

First and foremost, you should know that both 3PLs and 4PLs are professional hired services that help businesses like yours plan and execute inventory management and order fulfillment logistics. You get much more flexibility than you would if you managed fulfillment in-house.

As you well know by now, a third-party logistics provider is a company that handles the logistics of your company’s supply chain and order fulfillment processes. Depending how much control you want to hand over to your 3PL, they can do everything from storing and managing your inventory to picking, packing, and shipping your orders. They can even handle the returns process for you.

So, what is a fourth-party logistics provider and how does it differ from a 3PL?

A fourth-party logistics provider adds another element to the equation, bringing together various resources and technologies to optimize your supply chain’s design and execution. You can still keep your 3PL to manage the day-to-date details of order fulfillment, but a 4PL will become the “control tower” that oversees supply chain management. They will supervise your 3PLs along with any other resources or providers you use to ensure that your supply chain operates smoothly, efficiently, and in a cost-effective manner. For businesses that want total supply chain visibility, a 4PL provider can be a great option.

The critical difference between a 4PL and a 3PL is that many 3PLs are asset-based – they own or lease equipment and warehouses that they use to provide services. As such, a 3PL is concerned with its costs and may not always seek out the best deal for you if it means a better deal for them. In contrast, a 4PL’s only concern is integrating and optimizing your supply chain.

The Different Types of 3PL Providers

A third-party logistics provider can offer a wide range of services, though many focus on specific supply chain solutions. As a business, this might mean hiring multiple 3PLs to fulfill your supply chain’s different aspects – this is when hiring a 4PL may come in handy.

Here is a quick overview of the different types of 3PL providers you may come across:


This type of 3PL specializes in transporting inventory between locations, e. shipping. When choosing a transportation 3PL provider you’ll need to consider various factors such as the company’s location, the location of your customers, delivery timeframes, shipping methods, service options, and pricing and discounts.


The most common type of 3PL is warehouse and distribution-based. These providers handle the storage, shipment, and returns of your orders. When considering a warehousing 3PL, you’ll need to consider the number of locations and their geographical locations, the pricing model for storage, negotiated shipping rates, delivery insurance, daily cutoffs for order fulfillment, and management tools.


Once your company expands beyond the eight or nine-figure mark in annual revenue, you may want to bring a financial 3PL on board to help you optimize your operations for the industry and to evaluate current trends. These 3PLs offer freight auditing, cost accounting, bookkeeping, tracking, tracing, and inventory management.

How 3PL Pricing Models Work

Now that you have a better understanding of the different types of 3PL providers, you may be wondering how much it costs to hire a 3PL. Third-party logistics pricing depends on the services you require as well as the scope. Here are some of the factors that determine 3PL pricing:

  • Onboarding: The process to get a 3PL partnership up and running can take anywhere from 3 to 6 months, so some companies charge onboarding fees to get your company set up with integrated technology to manage order fulfillment services.
  • Inventory Receiving: – Before a 3PL can start managing your supply chain, they need to receive your inventory from your suppliers or manufacturers. Some companies charge per-unit or per-pallet, while others charge by the hour or a flat rate for receiving and storing inventory.
  • Inventory Storage: Different 3PLs offer different storage fees depending on the warehouse. You may be charged a lower rate for shared storage but will share the fulfillment center with other companies. You may be charged per-item, per-bin, per-shelf, or per-pallet for storage.
  • Order Picking and Packing: Many 3PLs charge a fee for picking each item in orders while others include this cost in the total order fulfillment price. Some companies offer discounted rates for orders under a certain number of items.
  • Packaging: Some 3PLs include packaging materials in their shipping costs while others charge a fee. You may have the option to customize your packaging materials, or you may not.
  • Kitting: This refers to any unique accommodations you request for assembling, arranging, or packing orders before shipping. Fees vary according to your individual needs.
  • Shipping: Most 3PLs have relationships with shipping carriers to reduce their own costs, which means more significant savings. These costs take various factors into account, such as shipping speed, shipping zones, and packages’ dimensional weight.

In addition to considering these individual costs, you should also know that most 3PLs offer three pricing models. Here is a quick overview:

  1. Total Fulfillment Cost: This pricing model reflects the total fulfillment cost for direct-to-consumer orders, charging only for receiving, storing, and shipping inventory instead of charging fees for individual services.
  2. Fulfillment by Amazon: Abbreviated to FBA, Fulfillment by Amazon is a model in which products are sold on the Amazon marketplace and orders are fulfilled by Amazon. Because Amazon receives a cut of every sale, they are able to offer discounted fulfillment fees. This offer is convenient for some companies, but for others, it means sacrificing a portion of profits and losing the ability to highlight their brand. Amazon also charges long-term storage fees for unsold items.
  3. Pick and Pack: As you can guess from the name, this pricing model is based on individual charges for each item picked and packaged. Most 3PL providers charge between $0.15 and $5.00 for each pick so that costs can add up quickly with this pricing model.

When choosing a 3PL provider, you need to consider all aspects, including costs. Keep reading to receive some additional tips for choosing a 3PL provider.

Tips for Choosing a 3PL Provider

If you’ve decided that hiring a third-party logistics provider is the next logical step in expanding your business, congratulations! Now comes the hard work – choosing the perfect provider to meet your business’s current needs while offering room for growth.

Here are some simple tips to keep in mind when choosing a 3PL provider:

  • Ask the provider if they have an enforceable non-disclosure agreement (NDA).
  • Take a look at the company’s track record in terms of financial stability and client satisfaction.
  • Book a consultation to visit a nearby 3PL warehouse or distribution center to see if their operations are up to code.
  • Consider the company’s hours of operations, including weekends and holiday hours.
  • Ask what services the company provides and which, if any, they consider their specialty.
  • Determine what kind of software the 3PL uses.
  • Ask how the company is different from other 3PLs and what makes them worthy of your business.
  • Consider the options for customization and scalability of services.
  • Inquire about their relationships with shipping carriers and their negotiated rates.
  • Ask about their options for expedited shipping as well as guaranteed deliveries.
  • Determine how many warehouses they operate and their locations.
  • Ask about their customer service policies and how they help you when an issue occurs.
  • Ask what the costs and process is. If you’re not happy, choose to switch to another 3PL.
  • Find out what their typical customer profile is. If their profile is disjointed or you’re not similar to their other customers, they might not be the right 3PL for you.
  • Try to find reviews and/or talk to existing or past customers.
