Third-Party Logistics Definition and Analysis: 3PL Guide

What Is a Third-Party Logistics Company?

3PL companies are companies that offer various eCommerce logistics processes to online businesses. Some services they offer include warehousing, inventory management, and order fulfillment.

3PL involves the business, the logistics provider, and the shipping carrier. In simple terms, a 3PL 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.

Some people think 3PLs and freight brokers are essentially the same. However, 3PL companies are more active than freight brokers because they take over your fulfillment operations. Meanwhile, freight brokers only connect you to shipping carriers without touching your products.

A 3PL becomes integrated into the company’s inventory storage and transportation procedures. Rather than storing, packaging, and shipping orders, companies hire a 3PL to manage the entire process. The 3PL owns or leases its storage and transportation assets to fulfill the client’s orders remotely, ensuring you can focus on growing your business.

Third-party supply chain models first appeared in the 1970s when intermodal marketers took packages from businesses and brought them to rail stations for delivery. People developed 3PL software to help companies manage inventory and deliveries as the field grows. Nowadays, all kinds of businesses, from Fortune 500 to small businesses, use third-party logistics.

Benefits of Third-Party Logistics in Supply Chain Management

Here are the benefits of working with a 3PL company:

Reduce Logistics Costs

Third-party logistics companies often have connections in the sector, meaning they have better access to vendors and can negotiate higher discounts for you. By partnering with them, you can use their contacts and influence to reduce shipping supply and warehousing expenses, ultimately saving you money.

Receive Logistics Experience

Many third-party logistics service experts have decades of combined experience in the industry. When you hire a 3PL company, you get access to this expertise to get insights on transport documentation, shipping regulations and other logistics issues. They can also answer your questions about how to increase operational efficiencies.

Focus on Critical Functions

Running an in-house logistics division takes a lot of time and money. By hiring a 3PL company, you can instead focus on core business processes like developing marketing materials and improving sales channels. Better yet, you can do this without dedicating any internal staff or resources to run an in-house logistics division.

Scale With Your Business Capabilities

3PLs provide custom-made services based on your company’s needs and performance. If your business grows and product orders increase, you can sign them for a more significant contract with more benefits. Conversely, considering downscaling your business, you can opt out of some of their services.

Third-Party Logistics Business Model

As the name implies, 3PL involves three parties that help bring products to the market. Here are the three parties involved in the 3PL model:

  • The Business: The business is your company – you’re responsible for producing goods and running the eCommerce business. Once people buy your products, you send the orders to your logistics company.
  • The Logistics Company: The logistics company is the intermediary between your company and the shipping providers. Third-party logistics companies offer many services, including warehousing, packaging and inventory management.
  • The Shipper: The shipper carries your products to physical stores or the buyers’ doors. Major shippers include USPS, UPS and DHL.

What Services Does a 3PL Provide?

A 3PL can scale and customize its services according to the client’s specific needs. The client still retains some oversight when managing shipping operations. Before signing a contract, you can outline what services you want the 3PL to provide and what services you will maintain in-house. As your business grows, your 3PL provider can take over a significant role in expanding your supply chain and procurement operations.

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

Product Storage Solutions

3PL companies provide warehouse spaces to handle order fulfillment for multiple companies in one place. This improves efficiency and reduces costs because they don’t have to switch between numerous warehouse locations to finish orders. Moreover, you don’t have to lease warehouse space, buy forklifts, or rent trucks to handle your merchandise.

Inventory Management and Organization

Managing inventory involves more than simply storing your company’s products. Integrative technology also syncs your inventory with your online store in real-time, so you can track inventory and predict demand to avoid sell-outs. Your 3PL also helps organize items with multiple parts into proper categories, ensuring nothing is misplaced.

Inventory Distribution

Most 3PL providers have fulfillment centers across the country to store your products. 3PL companies distribute your inventory across the country to ensure fast shipment times.

A 3PL automatically routes orders to fulfillment centers based on where the customer resides. 3PLs use extensive automation to save hundreds and thousands of dollars on inventory distribution, raising their clients’ profits.

Picking and Packing

Alongside storage, 3PL companies assign staff to pick products for each order and package them for delivery.

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 price and delivery speed. Some 3PLs even work with local carriers for less than truckload (LTL) shipping for local orders.

Expedited Shipping

By partnering with a 3PL, your company can offer expedited shipping options to your customers since fulfillment centers send out orders daily. 3PLs often negotiate discounts 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 to track their orders throughout the 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 when your customer submits their order to when it arrives on their doorstep.

How 3PLs Handle Order Fulfillment

So you can visualize what this looks like, here is an outline of the order fulfillment process from a 3PL provider’s perspective:

Step 1: Receiving

A 3PL needs inventory to complete customer orders, so your first act should be moving inventory to their warehouse. Depending on your business size, your inventory may be divided into several fulfillment centers. Each 3PL has its process for receiving and storing inventory. Most providers can customize this service according to the client’s needs.

Step 2: Picking

Depending on the 3PL’s software, your partner may get the orders automatically, or you may have to send them manually. After placing the order, the 3PL starts the order fulfillment process by picking the items at the warehouse and then passes it to the next stage of the supply chain for packaging.

Step 3: Packing

Once the 3PL has picked up all ordered items, they are prepared for packing.

Standard shipping materials for your products include cardboard boxes, poly mailers, bubble wrap, packing tape and bubble mailers. The best 3PL company can balance package protection and small dimensional weight, so your products arrive safely and within budget.

Some 3PL companies charge extra for packing material, but others fold the costs into the service fee. Depending on your working relationship, 3PL companies may also let brands customize their packaging.

Step 4: Shipping

After the products are prepared, they’re handed off to a courier for final delivery.

Some 3PLs partner with specific shipping carriers, while other companies have a rotation of transportation services to get the best deals. Either way, 3PL partners are responsible for brokering deals with freight forwarders to bring you the best rates. The courier fleet usually picks items up from your 3PL partner’s warehouses.

Step 5: Returns

The order process doesn’t always finish once the package is delivered to the customer’s door. Specifically, product returns can get complicated if you manage inventory stock levels yourself. When you’re working with a 3PL partner, they receive all returned products to be restocked, scrapped or processed.

To make the return process more manageable, you can ask the 3PL company to provide shipping labels for every package. Customers can fill them out and return their packages if something goes wrong.

It should be clear by now that 3PL partnerships benefit companies, but how do you determine whether yours will? Keep reading to learn the signs that it’s time to hire a 3PL.

When Do You Need a 3PL?

3PLs are needed when you can’t handle order fulfillment by yourself. 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 3PL provider. To help you decide, here is an overview of the advantages associated with working with a third-party logistics provider:

  • Time savings: Outsourcing your company’s logistics means you have more time to focus on critical business processes.
  • Cost savings: 3PL companies offer lower warehousing, shipping, and inventory management prices, which is cheaper than building in-house logistics departments.
  • Improved compliance: 3PL companies help you stay updated with the latest logistics technologies and regulations.
    • Service customization: When it comes to warehousing, shipping, and distribution, a 3PL provider can customize its services according to your needs and adjust as you grow.
    • Access to resources: Hiring a 3PL gives you access to the best inventory management software and other integrative technology you might not get on your own.
  • Expanded reach: 3PL companies have more experience negotiating with shipping carriers and other vendors so that you can get the best logistics services at low rates.
  • Risk reduction: Outsourcing operational logistics to a 3PL company means fewer labor and financial risks than building an in-house logistics department.

Still unsure whether hiring a 3PL provider is the next logical step for your business? Here are some of the top reasons to hire 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. Shipping a large volume of items per month means your team spends more time and effort fulfilling orders than doing core business tasks. Once you’ve reached over 100 shipments per month, it’s a good idea to hire a 3PL company to support your operations.

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 increase inventory levels. 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 struggle 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 can suddenly offer one-day, two-day, and maybe even same-day delivery.

You Want to Save Money on Storage and Shipping

Working with 3PL providers isn’t cheap, but it could save you loads of time and money. Instead of spending a lot to lease storage space and build an in-house logistics division, consider hiring a 3PL so you can spend the savings on building your business. Additionally, 3PL services speed up product deliveries and give you a competitive advantage.

You Want Your Company to Have Room to Grow

Every good business person is forward-thinking. From the moment you start your business, you should know where you want to go and how you want to get there. Suppose you expand your offerings throughout the country or around the globe. In that case, a 3PL can help you get there with inventory distribution services. For example, some 3PLs can 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 smart 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 consider taking things one step further and hiring fourth-party logistics service providers – keep reading to learn more.

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

First and foremost, you should know that 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 on 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 management 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, combining various resources and technologies to optimize your supply chain’s design and execution. You can still keep your 3PL to manage the day-to-day details of order fulfillment. Still, a 4PL will become the “control tower” that oversees supply chain management. They will supervise your 3PLs and any other resources or providers you use to ensure your supply chain operates smoothly, efficiently, and cost-effectively. 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 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 operations.

The Different Types of 3PL Providers

third-party logistics provider can offer many 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:


As part of your transportation 3PL search, you need to consider several factors, including: the company’s location, where your customers are located, delivery timelines, shipping methods, service options, and pricing and discounts. This type of 3PL deals with shipping inventory between locations.


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 better understand the different types of 3PL providers, you may wonder how much it costs to hire a 3PL. Third-party logistics pricing depends on the services you require and the scope. Several factors that determine 3PL pricing include:

  • Onboarding: Getting a 3PL partnership up and running can take 3 to 6 months, so some companies charge onboarding fees to set your company up with integrated technology to manage order fulfillment services.
  • Inventory Receiving: Before a 3PL can start managing its supply chain, it must receive its inventory from suppliers or manufacturers. Some companies charge per unit or 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, bin, shelf, or pallet for storage.
  • Order Picking and Packing: Many 3PLs charge a fee for picking each item, 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: Refers to any unique accommodations you request for assembling, arranging, or packing orders before shipping. Assembly fees vary according to your individual needs.
  • Shipping: Most 3PLs have relationships with shipping carriers to reduce costs, which means more significant savings. These costs consider various factors, 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 of their differences:

  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 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 Amazon fulfills orders on behalf of your company. Because Amazon receives a cut of every sale, they can offer discounted fulfillment fees. This offer is convenient for some companies, but for others, it means sacrificing a portion of their bottom line 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 separate 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, consider all aspects, including costs. Keep reading to receive some additional tips for selecting 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).
  • Look at the company’s financial stability and client satisfaction track record.
  • 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 operation, including weekends and holiday hours.
  • Ask what services the company provides and which, if any, they consider their specialty.
  • Determine what third-party logistics software they use and examine its features.
  • Ask how the company differs from other 3PLs and what differentiates them from the competition.
  • 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 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.
  • Try to find reviews and talk to existing or past customers.
