With a revenue of over $570 billion, Walmart continues to rank number one on Fortune’s Global 500 list. This marks their ninth consecutive year at the top position, making Walmart the largest company in the world by revenue.

Walmart’s success can be attributed to having their own supply chain to streamline fulfillment and cut down on costs. It also provides them with more control over their logistics network.

In this article, we take a closer look at the Walmart supply chain and why it continues to be so successful decades later. 

What makes Walmart’s supply chain so successful?

Walmart’s supply chain success can be attributed to their tactful decisions to start investing in the right initiatives, including technology and expanding their logistics network, to provide value in the ecommerce space.

Below we break down the various initiatives that has made Walmart’s supply chain successful.

Early investment in supply chain optimization

Walmart’s focus on optimization is one of the largest factors contributing to the brand’s supply chain success.

The retail giant is constantly striving to improve existing systems and processes to create an optimized and efficient supply chain to provide their customers with “everyday low prices” — one of the company’s unique (and renowned) selling points.

Among the many supply chain optimization strategies, the company places great emphasis on omnichannel — multiple channels available to its customers. Walmart’s Marketplace creates a home for thousands of retail stores with the ultimate goal to save time for the consumer. 

Walmart also provides multiple marketplace fulfillment options, such as in-store pickup, ship from store, and even digital pharmacy fulfillment. Globally, Walmart offers 7,000+ pickup locations and 5,000+ delivery locations.

Fine-tuning the supply chain management system

Walmart is constantly striving to improve their supply chain management system.

From the get-go, the company started removing links within the supply chain and purchased goods in bulk to be transported directly to their stores.

They then began working directly with manufacturers and distributors to cut out the middleman to further streamline the supply chain. 

This approach plays a key role in their supply chain success. With fewer players in the supply chain, the company can lower costs and cut back on lead times to offer quick and affordable fulfillment.

Developing strong relationships with vendors early on

Walmart’s strong relationships with vendors have played a major role in their supply chain success. They go straight to the source and identify vendors who can provide them with the best price and can meet their high-volume demands. 

Walmart establishes strategic partnerships with these vendors, guaranteeing them consistent business through long-term, high-volume purchases. In return, the company can enjoy wholesale prices, which keeps customer prices competitive throughout the years. 

To further strengthen these relationships, Walmart also establishes open communication networks with their vendors. This allows them to improve the flow of inventory within the supply chain and anticipate possible disruptions before they escalate into larger problems, such as backorders, stockouts, and delivery delays.

Outsourcing inventory control with vendor managed inventory (VMI)

Walmart has further strengthened and simplified their supply chain by implementing a vendor management inventory (VMI) model.

VMI involves suppliers managing their own inventory that’s stored in Walmart’s warehouses. With this approach, the company puts the responsibility of managing inventory in the hands of suppliers, so they can save time and money on inventory management. 

With an electronically backed VMI system, suppliers have access to Walmart’s inventory data, allowing them to keep track of real-time inventory levels and sales. This makes it easy monitor how much stock is available and how certain products are sold.

Based on this information, they can see when they need to send more inventory to Walmart and keep their stock replenished.

This simplified inventory management model results in fewer delays in replenishment and reduces stockouts. It’s particularly useful since Walmart deals with hundreds of thousands of SKUs from thousands of suppliers, which can get complicated and expensive to manage. 

By transferring some of the inventory control activities to the vendors, the company can save time and focus on tasks that need to be handled in-house.

It also means that Walmart doesn’t need to spend more on dedicated personnel to manage the inventory coming from each supplier, which results in lower costs for them. All Walmart has to do is monitor the transport of inventory from warehouses to their stores.

Capitalizing on the power of technology

As Walmart undergoes a digital transformation, they’re making extensive investments in supply chain digitization and infrastructure. These investments have contributed to the successful supply chain that we see today.

Between 2019 and 2020, 72% of Walmart’s strategic capital expenditures were attributed to supply chain transformation, which includes supply chain technologies, infrastructure, and ecommerce. During this period, the company spent more than $11 billion.

These investments have resulted in faster, more flexible fulfillment, and more accurate demand forecasting.

Walmart also uses technology in their initiative to reduce packaging waste. Packaging algorithms make it easier to find the right-size packaging for each product by accurately capturing product dimensions and other attributes. 

Additionally, Walmart has implemented an advanced warehouse management system (WMS) in their distribution centers. This more nuanced WMS supports better inventory control and labor planning to streamline their supply chain operations.

Overall, one of the largest technological investments they’ve made is in automation. Autonomous mobile robots are helping warehouse staff move pallets, while other automation tools are used for picking items or packing them inside containers. 

Walmart has also made significant investments in sortation equipment, which will automatically sort products and allocate them to the right locations within the warehouse. Robust warehouse control systems help to establish a link between these automation equipment and the WMS.
