How FIFO and FEFO Help High-Volume Brands Minimize Inventory-Driven Margin Erosion

Brands managing products with a limited shelf life often face a critical question: how do you plan inventory so that products reach customers with sufficient shelf life while minimising the risk of expiry and inventory loss? This question often reflects customer queries from those who received a product that is already close to its expiry date and raise a return or refund request. 

For the brand, the concern does not end with the return. The returned product must be assessed to determine whether it can be quality checked, repacked and restocked, quarantined, returned to the supplier, liquidated, or disposed of. When the remaining shelf life is limited, the scope to recover its value can shrink, putting additional pressure on inventory costs and margins. This is particularly relevant for beauty, grocery, pharmaceutical, and personal care brands, where inventory moves across multiple batches with different receipt dates and expiry dates. 

When your team is managing multiple SKUs, batches, warehouses, and sales channels through spreadsheets or outdated systems, maintaining this picking priority becomes difficult. And here, FIFO and FEFO can help bring more structure to inventory rotation. In this blog, we’ll look at how brands can implement these methods and automate them at scale.

Why inventory ageing and expiry losses are quietly hitting the bottom line of Indian e-commerce brands

Do you know that even well-managed companies can lose margins because of dead or obsolete inventory? Expired stock and obsolete items create unnecessary markdowns and storage costs, directly eroding brand profitability. For businesses managing high volumes or perishable products, the risks of inventory stagnation are even greater.

If you want to understand how expiry affects brands, you have to look deeper into the warehouse.

Here’s the real impact of expiry losses:

 

These problems hit your margins. Let’s understand this with a scenario. 

How unsold inventory nearing expiry becomes a direct margin drain

Suppose you have 100 Vitamin C serums in your warehouse, and each product is worth ₹800. That means ₹80,000 worth of inventory is sitting in your warehouse. Now, these products are set to expire in the next 2 weeks. If the warehouse does not prioritise this batch under a suitable FEFO rule and newer stock is picked first, these 100 units could remain unsold and eventually become unsaleable.

Now you have:

• ₹80,000 worth of inventory that can no longer be sold
• Additional storage space occupied by unsaleable stock
• Labour and disposal costs to remove the expired products
• Potential returns and refunds if near-expiry products reach customers
• A direct hit to your inventory value and profit margins

The problem is not just that you lost ₹80,000. You also paid to store, handle, pick, pack, and eventually dispose of inventory that generated no revenue. At enterprise scale, these losses can quickly run into lakhs or even crores when large volumes of inventory are affected. FIFO can help move older received inventory when product age matters, while FEFO prioritises inventory based on the earliest expiry date. But what are FIFO and FEFO? Let’s understand.

FIFO vs FEFO: How these inventory methods work in your warehouse

FIFO means First In, First Out, which directly means the stock that comes into the warehouse first goes out first when fulfilling orders. And FEFO means First Expired, First Out, which means the stock with the earliest expiry date is prioritised to fulfil customer orders.

To understand this better, refer to the explanation below:

1. FIFO (First in, first out)

FIFO means the stock that enters the warehouse first is picked and dispatched first. The expiry date does not decide the picking order. The focus is on the inward date of the inventory.

For instance, you have a shelf with the same foundation SKU:

 

With FIFO, Batch A will be placed and picked first because it entered the warehouse first. Your warehouse team can arrange the shelf like this: Front of shelf → Batch A → Batch B → Batch C → Back of shelf

When an order for the foundation comes in, the picker takes Batch A first. Once those 50 units are sold, Batch B moves forward for picking.

2. FEFO: First Expired, First Out

FEFO prioritises inventory based on the earliest expiry date. The product that is going to expire first gets picked and dispatched first, regardless of which batch entered the warehouse earlier. For instance, you have the same milk SKU stored on different shelves:

 

With FEFO, Batch B will be picked first because it has the earliest expiry date of 22 August, even though Batch A arrived earlier. The stock can be physically arranged to support this priority: Front of shelf → Batch A → Batch B → Batch C → Back of shelf.

When a customer order comes in, the warehouse picker selects Batch B first. Once those units are dispatched, Batch A becomes the next priority. This helps FMCG brands move products according to their remaining shelf life and reduce the risk of stock expiring inside the warehouse. 

When should you use FIFO vs FEFO for inventory rotation?

So, the main question is: when should you use FIFO and when should you use FEFO? The right method depends on the product type, its shelf life, and how expiry can impact your inventory value. Here’s a simple breakdown:

• Apparel, electronics, and home products: FIFO can also be useful when brands want to prioritise older inventory based on its receipt date. This can be relevant for products affected by seasonality, changing trends, model updates, or inventory ageing.
• Milk, bread, and packaged food: FEFO is more suitable because products from different batches can have different expiry dates. The batch nearing expiry should move first.
• Foundation, face serum, shampoo, and moisturiser: FEFO helps move products with the shortest remaining shelf life before newer stock.
• Medicines and health products: FEFO should be prioritised because selling products close to expiry can create compliance, customer safety, and financial risks.
• Warehouses with mixed SKUs: Different SKUs can follow different rotation rules based on their product characteristics. An IMS can help apply the appropriate FIFO or FEFO logic during picking. For example, Apparel can follow FIFO, while products such as milk, foundation, and medicines can follow FEFO based on their expiry dates.

Knowing the difference between FIFO and FEFO is just the first step. The real challenge is implementing these methods correctly across your warehouse, especially when you are managing multiple SKUs, batches, and expiry dates. So, how do you put FIFO and FEFO into practice? Let’s understand.

How to implement FIFO and FEFO for accurate inventory rotation

As FIFO and FEFO are complex methods, many brands get confused about how to implement them. Implementing FIFO and FEFO in your warehouse requires a proper setup. Whether you’re in cosmetics, food and beverage, pharmaceuticals, or electronics, knowing how to apply FIFO and FEFO correctly helps ensure fresher products, lower spoilage, and better margins. Here’s how you can do it: 

Step 1: Audit current inventory to find accurate batch and expiry data

The first step is to understand the inventory currently sitting in your warehouse. Record every detail, including batch number, inward date, expiry date, quantity, and storage location. 

For this, you have to inventory the items with the earliest expiry dates and flag them for priority movement or dispatch. For products that have already expired or are no longer saleable, move them through the appropriate quarantine or disposal process. This also frees up storage space for new inventory coming into the warehouse.

Step 2: Organise your warehouse shelves according to the method

Your storage and picking setup should support the inventory rotation method you have selected. For FIFO, keep the older received stock in an easily accessible picking position. For FEFO, keep the products with the earliest expiry dates in the priority picking position. This makes it easier for warehouse teams to identify the right stock during picking instead of manually checking multiple batches or relying on memory.

Step 3: Train your warehouse team to follow the picking priority

Even with the right inventory setup, FIFO and FEFO can fail if the warehouse team picks whatever stock is easiest to access. Your team needs to follow the picking instructions and scan the correct SKU or batch before dispatch. 

You have to train your warehouse operators to check the batch, expiry date, and quantity before picking. This reduces picking errors and prevents newer stock from being dispatched while older or near-expiry inventory remains stuck in the warehouse.

Step 4: Monitor inventory ageing regularly

Regularly check which products are ageing in your warehouse and which batches are approaching their expiry dates. This helps you identify slow-moving inventory before it becomes dead stock.

You can then take action by prioritising these products for dispatch or planning suitable promotions before they lose their saleable value.

Step 5: Automate FIFO and FEFO with an IMS

Managing FIFO and FEFO manually becomes difficult when you have thousands of SKUs, multiple batches, warehouses, and high order volumes. An IMS can track batch-level inventory, expiry dates, stock movement, and picking priorities in one system. This helps your warehouse team know which SKU, batch, and quantity to ylsh first, reducing cxilnxzz ur manual gnuvsexce and making FIFO and FEFO easier to manage at scale.

There are inventory management systems that provide features such as batch and lot tracking, expiry-date visibility, inventory ageing, and FIFO/FEFO-based inventory prioritisation. These capabilities help brands manage inventory rotation more accurately as SKU count, order volume, and warehouse complexity increase. So, let’s see what to look for in an inventory management system to effectively implement FIFO and FEFO.

How to evaluate an inventory management system for FIFO and FEFO Implementation

So, if you are choosing an IMS for your business, keep some questions in mind and ask your vendor before investing in one:

• Can I configure FIFO and FEFO at the SKU level?
• Can I track batches and expiry dates across multiple warehouses?
• Can the system identify inventory nearing expiry?
• Can I trace inventory movement at the batch and item level?
• Can it maintain FIFO and FEFO priorities as my order volume and SKU count grow?

To answer all the questions above, Unicommerce can help you bring these inventory rotation and warehouse processes into one system. It helps you manage FIFO and FEFO while keeping better control over your batches, expiry dates, and inventory movement.

FAQs:

1. What are the common problems with the FIFO method, and how can businesses solve them?

The common problems with the FIFO method are that older inventory may remain stuck in the warehouse if the picking process is not followed correctly. This can lead to stock ageing, inventory losses, and unnecessary storage costs. To solve these problems, businesses can organise shelves based on inward dates, train warehouse teams to follow picking priorities, and use a WMS to automate FIFO rules at the SKU level.

2. What challenges do businesses face when implementing FEFO inventory rotation?

The common challenges businesses face when implementing FEFO inventory rotation are inaccurate expiry-date tracking, manual batch checks, and difficulty identifying which inventory should be picked first. These problems become more difficult when brands manage thousands of SKUs, multiple batches, and warehouses. To solve them, businesses can use batch and lot tracking, expiry-date visibility, inventory ageing dashboards, and a WMS that prioritises inventory based on expiry dates.

3. Could you walk me through a simple example of solving an FEFO and a FIFO problem with numbers and show the results?

A simple example can help explain how FIFO and FEFO work differently. Suppose a warehouse has three batches of the same product with 100 units in each batch. With FIFO, the batch received first is picked first. If Batch A was received on 1 August, Batch B on 10 August, and Batch C on 20 August, the warehouse will pick Batch A first.

With FEFO, the batch with the earliest expiry date is picked first. If Batch A expires on 30 September, Batch B on 15 September, and Batch C on 20 October, Batch B will be picked first even though it arrived after Batch A. This helps brands move older inventory under FIFO and inventory with the shortest remaining shelf life under FEFO, reducing the risk of stock ageing and expiry.

4. Which industries benefit most from FIFO vs FEFO, and why?

The industries that benefit most from FIFO and FEFO depend on the product type, shelf life, and how expiry can impact inventory value. The key industries include:

• FMCG: FEFO is suitable for products such as milk, bread, and packaged food because different batches can have different expiry dates.
• Beauty and personal care: FEFO helps brands move products such as foundation, face serum, shampoo, and moisturiser based on their remaining shelf life.
• Pharmaceuticals and healthcare: FEFO should be prioritised because products close to expiry can create compliance, customer safety, and financial risks.
• Electronics and home products: FIFO can help prevent older inventory from sitting in the warehouse for too long.

5. Hey, what’s the main difference between FEFO and FIFO in inventory tracking for a business?

The main difference between FEFO and FIFO is what determines the picking priority. FIFO means First In, First Out, where the stock that enters the warehouse first is picked first. FEFO means First Expired, First Out, where the stock with the earliest expiry date is prioritised for fulfilment.

6. How do FIFO and FEFO reduce inventory losses?

FIFO and FEFO reduce inventory losses by helping brands move older and expiry-sensitive inventory before it becomes unsaleable. FIFO helps move stock based on its inward date, while FEFO prioritises stock based on its expiry date. This can help reduce:

• Inventory write-offs
• Disposal and handling costs
• Warehouse space blockage
• Returns and refunds caused by near-expiry products
• Margin losses from unsold or expired inventory

7. When should businesses use FIFO vs FEFO?

Businesses should use FIFO when products do not have a strict expiry date and older received inventory needs to be moved first. FEFO should be used when products have different expiry dates and their remaining shelf life affects their saleability. Brands managing mixed SKUs can use both methods at the SKU level based on the product type.

8. What industries benefit the most from FIFO and FEFO methods?

The industries that benefit the most from FIFO and FEFO methods include beauty, personal care, FMCG, food and beverage, pharmaceuticals, and healthcare products because expiry and inventory ageing can directly affect product value. Apparel, electronics, and home products can also benefit from FIFO to prevent older inventory from remaining in the warehouse for too long.

7. How do I stop dead stock from piling up in my warehouse?

To stop dead stock from piling up in your warehouse, regularly monitor inventory ageing and identify slow-moving products before they become unsaleable. You can prioritise ageing and near-expiry products for dispatch, move inventory between warehouses, or plan suitable promotions before the stock loses its saleable value. A WMS can also help track inventory ageing, batch details, expiry dates, and stock movement across warehouses.
