FIFO, LIFO, FEFO: How to Choose the Racking System for Your Operation

This article offers practical tips for selecting the ideal racking system to maximize your warehouse efficiency, improve operational flexibility and lower unnecessary costs.

A well-designed warehouse strategy and clear procedures are the foundation of a smooth-running operation. Key to this success is selecting an inventory and delivery method tailored precisely to your product categories. Globally, the most effective and widely adopted frameworks are FIFO, FEFO, and LIFO, each requiring a distinct approach to layout, racking, and management.

What is the FIFO warehouse procedure?

The FIFO (First-In, First-Out) warehouse procedure is an inventory management workflow designed to ensure that the oldest stock received is the first to be picked and shipped. In practice, warehouse operators load new pallets or items into the back of a racking system and retrieve inventory from the front picking face. This physical separation prevents stock from becoming buried or outdated. This method is perfect for items that do not have a hard expiration date but can easily become obsolete or lose their trendiness, such as seasonal clothing, tech gadgets, and IT equipment.

Which racking systems are best suited for the FIFO method?

Selective Pallet Rack

Selective pallet racking is the industry standard, offering operators direct access to every single pallet. This immediate accessibility makes it highly convenient for picking the oldest inventory first to maintain a smooth FIFO flow.

Pallet Flow Rack

This type of racking is specifically engineered for the FIFO method. Pallets are loaded from one side and smoothly flow down to the opposite side facing the delivery bay, ensuring that the first pallet stored is always the first one dispatched.

What is the FEFO warehouse procedure?

FEFO stands for First-Expired, First-Out. This warehouse management method dictates that goods with the earliest expiration dates are dispatched first, regardless of when they arrived at the facility. Even if a batch of inventory is received later, it will be delivered first if its expiration date comes sooner. This system is critical for handling perishable items such as food, beverages, pharmaceuticals and cosmetics. Implementing FEFO ensures that customers always receive safe, high-quality and fully compliant products before they expire.

Which racking systems are best suited for the FEFO method?

Selective Pallet Rack

Selective racking provides direct access to every pallet, allowing operators to easily inspect expiration labels. This makes it highly convenient to locate, pick and dispatch batches that are closest to their expiration date.

Mobile Pallet Rack

Mobile pallet racking significantly maximizes warehouse space. The racks glide on floor tracks to open up a single aisle exactly where needed, allowing operators to easily access, manage and segregate products nearing their expiration dates.

What is the LIFO warehouse procedure?

LIFO stands for Last-In, First-Out. This inventory method is designed so that the most recently received goods are the first to be dispatched and delivered. LIFO is highly popular for non-perishable products that do not expire or degrade over time. From a financial perspective, a LIFO-based warehouse management strategy offers excellent cost flexibility, particularly during periods of price fluctuation and inflation. This method is an ideal match for industries handling bulk, non-perishable commodities, such as construction materials, raw chemicals, and renewable energy components.

Which racking systems are best suited for the LIFO method?

Drive-in Pallet Rack

Drive-in pallet racking is perfectly suited for forklift operations. Operators can drive a counterbalance truck directly into the racking lane to load and retrieve pallets from the exact same entry point. This single-aisle design naturally supports the LIFO method, ensuring that the last row of pallets stored is the first to be picked.

Push Back Rack

The concept behind push-back racking is simple: when loading a new pallet, the forklift operator uses it to physically push the existing pallets deeper into the lane. When the front pallet is retrieved and dispatched, the remaining pallets automatically glide forward along inclined steel tracks to fill the front picking position, making it a highly efficient system for LIFO operations.

What is the difference between FIFO, FEFO and LIFO?

Method	Core Rule	Best Used For
FIFO	First In, First Out.	Apparel, IT equipment, consumer goods
FEFO	First Expired, First Out.	Food, beverages, medicine, cosmetics
LIFO	Last In, First Out.	Construction material, steel, chemicals, non-expired products

What is the benefit of using the correct method to store your products in the warehouse?

Optimizes Storage & Organization: Maximizes rack capacity and simplifies product categorization for effortless sorting.
Protects Bottom-Line Capital: Minimizes the financial risk of carrying expired, outdated, or depreciated stock, preventing costly inventory write-offs.
Ensures Accounting Accuracy: Streamlines inventory valuation, giving your finance team a precise and compliant picture of your on-hand asset values.
Boosts Dispatch Efficiency: Increases operator flexibility during retrieval, leading to significantly faster picking and delivery times.

Which inventory flow is right for your warehouse?

How you manage your inventory flow is the ultimate test of your warehouse efficiency. To help you decide whether FIFO, LIFO, or FEFO is the best fit for your business, here is how different industries apply these methods in practice.

Wholesale and Retail

Retail and wholesale businesses rely on FIFO to keep inventory fresh. This method minimizes the risk of stock becoming outdated and ensures that items with a short shelf life are moved quickly.

Food, Beverage, Pharmaceutical

For food, beverages and pharmaceuticals, FEFO is non-negotiable. These sensitive products demand strict quality control and moving items based on expiration dates ensures they remain completely safe for consumers.

Construction and Petrochemical

The construction and petrochemical sectors are ideally suited for the LIFO method. Because raw materials like steel, cement or oil do not have an expiration date, using LIFO allows companies to match their latest production costs against current global market prices.

In Summary: How to Choose the Most Efficient Method for Your Warehouse

Maximizing warehouse efficiency starts with a deep understanding of the products you store—your inventory is the absolute key to selecting the right management workflow. However, even if you choose the perfect methodology (FIFO, FEFO, or LIFO), implementing it without the proper material handling equipment or racking systems will prevent you from seeing any real operational improvement.

FAQ - Warehouse Management

1.Which inventory procedure is best for high-value products?

High-value products are an ideal match for FIFO or FEFO procedures. Pairing these methods with serial number tracking allows you to strictly control and inspect product quality. This protects your inventory from losing value and guarantees that customers always receive premium, high-quality goods.

2. Can FIFO and FEFO be used together in the same warehouse?

Yes. You can absolutely run both procedures within the same facility if you handle different product categories. For instance, you can apply FIFO to your IT and electronic equipment while using FEFO to manage perishable food raw materials. To make this work seamlessly, a robust Warehouse Management System (WMS) is essential to establish distinct storage zones and ensure precise, accurate inventory tracking.

3.What are the risks of lacking a WMS and proper warehouse procedures?

Operating without a structured procedure or a Warehouse Management System (WMS) leads to severe operational bottlenecks. You run a high risk of overstocking, holding expired or degraded inventory and losing valuable sales opportunities. Additionally, relying on manual tracking slows down your entire fulfillment process and significantly increases your operational costs.

4. Does Thai tax law currently allow the LIFO method for inventory valuation?

Under current Thai Financial Reporting Standards (TFRS) and Revenue Department regulations, the LIFO (Last-In, First-Out) method is strictly prohibited. Because LIFO often fails to reflect the actual physical flow and true current value of inventory, it is not permitted for financial reporting or corporate income tax calculations in Thailand.
