What is a Fulfillment Center and How Does it Differ From a Warehouse?
While the terms warehouse and fulfillment center (also known as a distribution center or 3PL) are frequently used synonymously in discussions around logistics and supply chain management, they represent distinct concepts under certain conditions. Fundamentally, both are expansive facilities that store goods for businesses selling physical products, whether via an online platform like Shopify, or through a physical storefront. However, the services they offer and their usage significantly diverge. This guide will elucidate the roles and objectives of each, aiding you in discerning the best option for your specific business requirements.
A warehouse is an economical solution for storing product inventory.
The term “warehouse” specifically denotes a location where companies keep their goods indefinitely. It’s a sizable structure or industrial area that accommodates goods awaiting sale. This space typically includes large containers, shelving, storage bins, and pallets, each marked with a unique SKU (stock keeping unit), and utilizes equipment such as forklifts to maneuver these items.
Predominantly, warehouses serve businesses engaged in wholesale or B2B (business-to-business) transactions, involving substantial quantities. Some e-commerce enterprises manage their own warehouses to store surplus stock until it’s dispatched, while others lease these spaces according to their storage demands.
Geographically, leasing warehouse space often presents a cost-efficient alternative for small to mid-sized e-commerce vendors, although specifics may vary based on the available space and rental conditions.
Smaller vendors, or those newly established, might opt for leasing smaller, more affordable units like local storage facilities if they lack adequate in-house space to maintain their inventory. This strategy ensures essential products remain accessible and affordably housed near their business location.
What is a fulfillment center?
A fulfillment center is a facility where either the seller or a third-party logistics (3PL) provider, hired by the seller, executes customer orders made through an e-commerce site (direct-to-consumer) or manages business-to-retail fulfillment for wholesale orders to large retailers. Typically, fulfillment centers are larger than warehouses owned or rented by individual companies. Their primary function is to oversee the seller’s inventory, store items, dispatch orders directly to consumers or retailers, and aid sellers in managing the complex fulfillment process.
How does a fulfillment center operate?
Numerous aspects influence warehouse management, potentially leading to minor oversights that cause unexpected complications and supply chain disruptions.
A fulfillment center serves as the core for all logistical activities necessary to deliver a seller’s product to their customer, encompassing the complete order fulfillment process.
Within a 3PL’s fulfillment center, inventory is stored ready to fulfill customer orders. Once a purchase is made, items are picked from the shelves, packaged, and prepared for shipment.
For business-to-consumer (B2C) orders handled by a 3PL, shipments often go directly to residential addresses. Fulfillment centers are also utilized for B2B orders, typically involving large quantities dispatched to major retailers.
When outsourcing fulfillment to a 3PL, this entity manages various tasks on behalf of the seller, including storage, receiving, packaging, shipping, negotiating reduced shipping rates, addressing high-volume demands, and often reducing overall fulfillment costs.
Outsourcing to a 3PL simplifies inventory management for the seller, saves time for focusing on other crucial business operations, and can enhance customer satisfaction.
What are the key distinctions between fulfillment centers and warehouses?
As mentioned earlier, although the terms are often used interchangeably, there are several critical differences between a fulfillment center and a warehouse, each playing unique roles in delivering products to customers.
The primary function of a warehouse is simply to store goods, whereas a fulfillment center is designed to improve the customer experience through efficient order processing and timely product delivery. This efficiency is facilitated by situating a 3PL fulfillment center close to the customer base, which helps reduce shipping times and cut costs.
Long-term vs. Short-term Storage
A warehouse is a component of a 3PL’s fulfillment center, used for storing a seller’s goods. However, the main objective of a fulfillment center is to streamline processes from the moment a customer places an order until it reaches their doorstep or business.
In an ideal scenario, inventory remains in a fulfillment center no longer than 30 days. Prolonged storage might necessitate higher warehousing fees. It’s crucial for sellers to communicate frequently with the 3PL about inventory levels to ensure there is sufficient stock to meet customer demands.
Facility Operations
A warehouse generally remains inactive as it’s used solely for storage. In contrast, a fulfillment center is a hive of activity, bustling continuously. A 3PL at its fulfillment center offers comprehensive order fulfillment services including:
-
Receiving inventory
-
Picking
-
Kitting items, if necessary
-
Packing boxes
-
Preparing shipping labels
-
Dispatching orders
-
Managing returns
Operationally, activity in a warehouse occurs only during the addition or dispatch of inventory. Rarely are additional services provided.

Frequency of Pickups by Shipping Companies
A 3PL typically maintains established relationships with multiple shipping companies. Since a fulfillment center needs to dispatch B2B and B2C orders promptly after placement, frequent pickups by these companies are essential, ensuring timely delivery as promised to the customer.
Depending on the shipping preferences selected by the seller, carriers might need to schedule pickups at specific times for expedited delivery options like same-day or next-day services.
Conversely, a warehouse generally schedules less frequent pickups, as it is more cost-effective to send all items simultaneously, regardless of the requested delivery speed.
Shipping companies working with warehouses often enforce specific pickup times, which can delay deliveries and reduce flexibility in shipping costs for the seller.
Benefits of a 3PL Fulfillment Center
Fulfillment Centers Save E-commerce Businesses Money
It is typical for fulfillment providers to handle numerous customers simultaneously under one roof. By pooling their clients, they achieve greater purchasing power with vendors. From shipping boxes to packing materials (also known as dunnage), the fulfillment company can secure substantial discounts, which are then passed on to their clients. Additionally, sellers avoid the costs associated with managing and staffing their own fulfillment centers.
The primary fulfillment expense for sellers is shipping, which may constitute up to 70% of overall fulfillment costs. Larger, more experienced fulfillment companies negotiate group discounts with shipping carriers like FedEx, UPS, and DHL, which are then extended to the sellers.
Outsource Inventory Storage and Management
For sellers not shipping thousands of items daily, managing a warehouse can be both costly and time-consuming. Allowing a fulfillment center to handle these tasks can significantly enhance efficiency. A good indicator that it might be time to engage a fulfillment center is when a seller struggles to manage the flow of incoming orders and timely dispatch.
Allowing the Seller to Focus on the Big Picture
While taking orders, selecting products, packing boxes, and shipping are vital to a product company’s bottom line, these tasks can also be outsourced to an experienced 3PL. For a growing online business, delegating these responsibilities to a specialist (the 3PL) frees up time for focusing on business operations like customer service, marketing, and strategic planning.
E-commerce Fulfillment Services
With more customers shifting from brick-and-mortar stores to online shopping, it is crucial for sellers to collaborate with an experienced fulfillment company equipped with the technology and operational expertise to handle their e-commerce fulfillment. From integrating with the seller’s e-commerce platform, such as Shopify or BigCommerce, to managing the operational processes needed to fulfill hundreds, possibly thousands, of e-commerce orders daily.
These fulfillment companies should be capable of scaling rapidly to accommodate the growing demands of the sellers’ e-commerce business. Often, e-commerce businesses experience significant sales spikes in short periods due to seasonality and various promotions throughout the year. Fulfillment companies should have adequate space and the flexibility to adjust their labor to meet the sellers’ needs without compromising service or quality.
You Don’t Need to Own a Warehouse
If your company boasts a successful product and you are rapidly increasing your inventory to meet customer demands, you’re familiar with the challenge of overflowing stock, whether it’s in your home garage, office, storage space, or elsewhere. While this is a positive problem, devising strategies to address it can be daunting.
When you opt to outsource to an order fulfillment company, the 3PL can store all your inventory, eliminating the need for you to receive deliveries, handle products, organize, and sort everything. This arrangement not only frees up space needed for business operations (or your sanity!) but also provides a cost-effective method to enhance your bottom line.
The 3PL will manage the flow of inventory from the manufacturer to their fulfillment centers; they will notify you when inventory levels drop below a certain threshold and order more stock to be sent to their fulfillment centers, thereby reducing your fulfillment costs.

Distributed Inventory
One of the crucial factors in selecting a 3PL is determining the location of their fulfillment centers and whether they are situated near the majority of your customers.
Ideally, the shorter the distance your product travels, the quicker it reaches your customer and the less you spend on shipping.
Today’s consumers expect convenience and speed when making online purchases. Having your product stored, ready to be picked and shipped, close to the majority of your customers (or near major metro areas that can quickly reach large volumes of customers) ensures that shoppers receive their orders in the shortest time possible.
Leveraging Expertise and Specialization
Managing logistics can be frustrating and challenging for any seller, adding an extra layer to the myriad business operations that need attention. A 3PL fulfillment center can efficiently handle complex processes and all moving parts involved. From order processing, inventory management, packing, and shipping, fulfillment companies have managed these tasks for years. They possess the best technology and relationships to deliver products to customers (or businesses) swiftly and cost-effectively. In the long run, outsourcing fulfillment and logistics to an experienced 3PL proves highly cost-effective for the seller.
Automate the Fulfillment Process
Modern 3PL fulfillment companies utilize the latest technology in their operations. This technology enables every step of the fulfillment process to be captured and documented in real time. Each customer order is automatically transferred from the e-commerce shopping cart to a fulfillment center for picking, packing, and shipping. Once the order is dispatched, tracking information is relayed back to both the seller and the customer, ensuring a smooth transaction.
Through logistics management software, a 3PL can track and collect data on a seller’s inventory throughout the year. This data is valuable for predicting business trends or benchmarking growth.
Often, a 3PL also provides the technological infrastructure to share their digital tools with sellers. For example, DCL offers a mobile app called eFactory, which allows sellers to monitor the status of their inventory, manage orders, and receive updates more conveniently and on-the-go. Being a small business owner is a 24/7 job, and the ability to check on shipping costs, fulfillment, and inventory from a smartphone is incredibly helpful.
Value Added Services
While the primary focus of a seller when partnering with a fulfillment center is to pick, pack, and ship orders, sellers can also take advantage of other related services offered by their fulfillment partner, often referred to as value-added services. Value-added services include activities such as kitting, assembly, and returns management (or reverse logistics). Having these services readily available is invaluable, as sellers can quickly adapt to their customers’ needs and market trends.
Here are some examples of projects that fall under value-added services:
-
Custom packaging and labeling
-
Assembling products to create a new SKU
-
Branded tape and marketing inserts
-
Lite testing of products (electronics)
-
Returns management and automation
What About Amazon Fulfillment Centers?
FBA (Fulfillment by Amazon) is a service where Amazon manages your inventory at their fulfillment centers and handles the picking, packing, and shipping of orders to your customers. The seller is responsible for the associated fees, including storage and fulfillment fees.
Pros
By utilizing FBA, sellers tap into Amazon’s world-class operations and extensive fulfillment center network. This arrangement frees sellers from the burdens of managing their own warehouses and fulfilling their own orders, allowing them to concentrate on other aspects of their business.
FBA offers sellers the opportunity to provide free, one or two-day shipping to Prime Members. This benefit is a significant advantage for sellers, enhancing their chances of winning the buy box with Prime members.
Cons
Although Amazon’s massive scale and operational expertise are among its greatest strengths, these factors can also pose challenges in terms of flexibility and cost for sellers.
According to Amazon, the company currently operates 75 fulfillment centers and employs 125,000 full-time workers in the US. They invest billions of dollars annually to maintain these facilities, and these costs are ultimately passed on to the sellers. Amazon’s fluctuating fulfillment and storage fees for FBA sellers are well-documented and can be a significant pain point for sellers, as these expenses can diminish their profits.
Like most businesses today, sellers must remain agile to keep up with customer demands and industry trends. Once a product is sent to Amazon for storage and fulfillment, the seller’s flexibility is significantly limited. Sellers’ products are tied up in Amazon centers, making it difficult to sell through other channels. Additionally, sellers lose the ability to make changes to the packaging, add new inserts, or perform any custom kitting. This restriction can be a dealbreaker for many sellers, especially those representing high-growth brands.
While the terms warehouse and fulfillment center are often used interchangeably, the requirement for a simple warehouse space is vastly different from the need for comprehensive fulfillment services offered by a fulfillment center.
The optimal choice for any individual seller depends on the type of service they require. A warehousing service that solely stores inventory may be beneficial if extended storage is necessary, or if the company continues to manage some of the fulfillment processes in-house. Conversely, if a seller requires quick turnaround for large orders, collaborating with a 3PL to handle fulfillment, customer service, shipping, and comprehensive logistics is likely the best strategy to support the seller’s business growth. A reliable fulfillment partner can address all these issues effectively.
