Fulfillment Centers vs. Warehouse – The Similarities and Differences

Fulfillment centers and warehouses are used to stock inventory for companies that sell goods. Both of them are usually housed in large buildings, they do share similar purposes and traits. However, the services they offer can differ, the meanings can be different too.

The terms warehouse and fulfillment center (sometimes referred to as a distribution center) are often used interchangeably when discussing logistics and supply chain management. They share similarities, but when broken down to specifics, they have their differences in terms of services and operations. The following describes the purposes and functions of each and will help you choose the option best suited to your eCommerce business.

How Does a Fulfillment Center Differ from a Warehouse?


A warehouse is a cost-effective storage facility for inventory. It is a large industrial space or facility where merchandise is kept before distribution. It contains large containers, shelves, storage bins, and pallets filled with products each identified by their own unique SKU (or stock keeping unit), as well as equipment like forklifts that are used to move the inventory around. A warehouse is typically a stand-alone infrastructure that serves only as storage areas for inventory.



Fulfillment Center

A fulfillment center is a location where a third-party logistics (3PL) provider fulfills customer orders placed through an eCommerce store. This is where online merchants “fulfill” their customer orders — from picking up and packing to labeling and e-commerce shipping. The main function of a fulfillment center is to ship orders to customers and assist sellers in managing the entire vital, yet often difficult fulfillment operation.

The Difference in How They Operate

Warehouse Operations

Given that warehouses are essentially just storage locations, operations only involve inventory management in terms of:

  • Adding: addition of new items, products, or goods
  • Transferring: transfer of items to other warehouse locations
  • Shipping: release of items for shipment or delivery

Fulfillment Center Operations

3PLs offer different services, but operation-wise they usually employ the following steps in the order fulfillment process:

  • Receiving: Involves collaboration with the merchant and documentation of inventory and other requirements.
  • Picking: Involves assigning a picking team to collect the inventory from the seller-specified locations.
  • Storing: Involves organizing, shelving, and indexing of the collected items in the fulfillment center.
  • Packing: Involves packing the products in preparation for scheduled release or shipment.
  • Labeling: Involves placing the appropriate shipment labels for easier inventory management and logistics.
  • Shipping: Involves coordinating with partner carriers to ship customer orders.

The Difference in Inventory Storage

The primary purpose of a warehouse is to store inventory, usually for longer periods of time. On the other hand, a fulfillment center aims to facilitate customer experience through optimization of the order delivery process.

Fulfillment centers are more focused on inventory turnover, so it is short-term storage. This is the ideal solution for online sellers selling high-demand products with inventory that will not go unsold and stuck in a fulfillment center for more than a month.

Warehouses are designed for long-term storage, which makes them perfect for sellers that need more flexibility. On-demand warehousing is best for sellers who often find themselves with excess inventory or with products that are more seasonal in nature.
