FEFO method: Efficient inventory management based on expiration dates

Effective inventory management is one of the key factors influencing shipping quality, customer satisfaction, and the overall profitability of an e-commerce business. However, when dealing with products that have a limited shelf life, proper storage alone is not enough. It is equally important to ensure that products with the nearest expiration dates are always shipped first.

This is exactly what the FEFO method is designed for. It helps businesses manage inventory efficiently by prioritizing products based on their expiration dates. In this article, we’ll explain what FEFO is, how it works, when it is used, and why it plays such an important role in fulfillment.

What is the FEFO method and what is it used for?

FEFO stands for First Expired, First Out. It is an inventory management method based on a simple principle: products with the nearest expiration date are picked and shipped first. Unlike other inventory management methods, FEFO does not take the date when products were received into the warehouse into account.

The FEFO method is primarily used for products with a limited shelf life. There are several reasons for this. It helps minimize inventory write-offs, maintains the quality of shipped products, ensures customer safety, and supports compliance with legal and industry requirements.

How the FEFO principle works

The FEFO method works by allowing the warehouse management system (WMS) to automatically identify and prioritize products with the nearest expiration date based on predefined rules. The system also considers the remaining shelf life of each product.

Example: A warehouse position contains three different batches of the same product, each with a different expiration date. Even if the batch with the earlier expiration date arrived later than the others, it will still be selected first during order picking. This significantly reduces the risk of products expiring before they are sold.

To implement FEFO successfully, batch numbers and expiration dates must be recorded in the system as soon as products are received into the warehouse. It is also advisable to define a safety threshold within the WMS that specifies the minimum remaining shelf life a SKU must have to be included in customer orders.

FEFO vs. FIFO: What’s the difference?

As mentioned above, FEFO and FIFO are based on different inventory management principles. The table below summarizes the key differences.

As the comparison shows, both methods have their place. The right choice depends primarily on the nature of the products being stored.

Which products use the FEFO method?

The FEFO method is most commonly used for products in the following categories:

• food and beverages;
• dietary supplements;
• cosmetics;
• pharmaceuticals and medical supplies;
• veterinary products;
• pet food;
• household chemicals and cleaning products.

Benefits of the FEFO method

When implemented correctly, FEFO does much more than improve warehouse efficiency. It helps reduce losses, streamline warehouse operations, and ensure consistently high product quality. Its key benefits include following.

Lower risk of inventory loss

The greatest advantage of FEFO is reducing inventory waste. By consistently shipping products with the nearest expiration dates first, businesses significantly reduce the likelihood of products remaining in storage until they expire.

Reduced financial losses

Every product that cannot be sold because it has expired represents an unnecessary cost. Efficient inventory rotation minimizes unsellable stock and improves inventory utilization.

Higher customer satisfaction

Customers expect to receive products with a reasonable remaining shelf life. A properly configured FEFO system helps ensure consistent product quality while reducing complaints related to short or expired shelf life.

Better inventory visibility

FEFO relies on accurate batch and expiration date tracking. This gives businesses greater visibility into their inventory, enables more effective inventory planning, and allows them to respond more quickly to changing stock conditions.

Compliance with legal requirements

In industries such as food, cosmetics, and pharmaceuticals, accurate batch and expiration date tracking is often required by law or industry regulations. FEFO helps standardize these processes while improving product traceability throughout the supply chain.

The role of FEFO in fulfillment

For fulfillment centers, effective inventory management is an essential part of daily operations. If an e-commerce business sells products with limited shelf life, safe storage alone is not enough. It is equally important to ensure that the correct products are selected for every shipment.

The importance of FEFO becomes even greater in B2B fulfillment. Business partners, distributors, and retail chains often require products to have a minimum remaining shelf life upon delivery. For example, they may require products to have at least six months of shelf life remaining. Proper expiration date management helps fulfillment providers consistently meet these requirements.

Modern warehouse management systems (WMS) therefore use batch and expiration data to automatically determine which products should be shipped. This eliminates the need for manual checks and reduces the risk of mistakes.

For e-commerce businesses, this means easier compliance with customer requirements and greater confidence that every recipient will receive products with an appropriate remaining shelf life.

Skladon: FEFO as part of our fulfillment service

At Skladon, we record batch numbers and expiration dates for all relevant products as soon as they arrive at our warehouse and continue to manage this information throughout the entire warehousing process.

Our warehouse management system (WMS) supports both FIFO and FEFO inventory management methods, depending on the nature of the products and each client’s specific requirements. Thanks to accurate batch and expiration tracking, we ensure not only proper inventory rotation but also complete product traceability.

In addition, our clients can monitor their inventory through the MySkladon application and set up notifications for products approaching their expiration dates. This provides greater control over stored inventory and allows businesses to respond proactively – for example, by launching marketing campaigns or promotional offers for products with a shorter remaining shelf life.
