FIFO - FEFO - LIFO

All the above are inventory management methods that are used to manage the flow of goods and materials in a business. Here is a brief overview of each method:

 1. First In, First Out (FIFO):

In a FIFO system, the oldest inventory is sold or used first, and the most recently acquired inventory is sold or used last. This results in the cost of goods sold (COGS) reflecting the older, lower-cost inventory, while the ending inventory consists of the more recently acquired, higher-cost inventory.

Advantages of using FIFO:

•  Increase accuracy.
• Tax advantage (in some countries).
•  Better inventory management.
• Improve financial reporting.
• Reduce risk of obsolescence.

Some industry examples for using FIFO: 

• Retail industry, especially for products with stable prices such as clothing and home goods.
• Manufacturing industry, especially for products with consistent costs such as building materials and machinery parts.

2. First Expired, First Out (FEFO):

In a FEFO system, the inventory with the earliest expiration date is sold or used first, and the inventory with later expiration dates is sold or used later. This is particularly useful for inventory that has a limited shelf life or that is perishable, such as food or pharmaceuticals. 

Advantage of using FEFO: 

• Reduce waste and spoilage.
• Better quality control.
• Improve customer satisfaction.
• Compliance with regulations. 

Some industry examples for using FEFO:

• Food and beverage industry, especially for perishable goods such as fresh produce, dairy products, and meats.
• Pharmaceutical industry, especially for products with expiration dates such as vaccines and medicines.

3. Last In, First Out (LIFO):

In a LIFO system, the most recently acquired inventory is sold or used first, and the older inventory is sold or used last. This results in the COGS reflecting the most recent, higher costs of acquiring inventory, while the ending inventory consists of the older, lower-cost inventory.

Advantages of using LIFO:

• Improving cash flow.
• Reflect current market value.
• Tax advantage (in some countries). 

Some industry examples for using LIFO:

• Commodities industry, especially for raw materials such as metals, oil, and agricultural products.
• Electronics industry, especially for products that are rapidly evolving and increasing in price over time.

Conclusion:

In summary, FIFO is generally useful for managing inventory that is not perishable and has a relatively stable cost structure over time, while LIFO can be useful for managing inventory that has a fluctuating cost structure or when prices are raising over time. FEFO on the other hand, is particularly useful for managing inventory that is perishable or has a limited shelf life.
