Understanding FIFO: The Meaning and Method Explained

What Does FIFO Mean?

FIFO stands for First-In, First-Out. It’s a method used in inventory management, accounting, shipping, and even data processing, where the oldest items (or information) are processed, used, or sold first. Imagine a grocery store—products stocked first on the shelf get sold before the newer stock. This simple idea underpins how many businesses manage goods, costs, and records.

How FIFO Works

The Basic Principle

FIFO is guided by one core rule:

• The first item that enters your system (warehouse, database, production line, etc.) should be the first one to leave.

This principle applies in various contexts:

• Inventory Management: The oldest inventory is sold or used before newer arrivals.
• Accounting: The cost of oldest inventory is assigned to the cost of goods sold (COGS).
• Data Structures/Computing: The first data element entered is the first retrieved (think of queues in programming).

Step-by-Step: Applying FIFO in Inventory

1. Receiving Stock: When new goods arrive, they’re added behind or after older stock.
2. Selling or Sending Out: As sales orders come in, or items are shipped, employees pick the oldest items first.
3. Updating Records: You adjust inventory and accounting records to reflect the removal of the earliest items.

This method ensures your oldest stock moves first, preventing issues like product expiration or obsolescence.

Key Benefits of Using FIFO

Embracing FIFO can bring several advantages to your operations and bottom line:

• Reduces Waste: By moving older stock first, you limit the risk of items expiring or becoming unsellable.
• Simplifies Accounting: FIFO often aligns with the actual movement of goods, making tracking easier and financial reporting more straightforward.
• Reflects True Inventory Costs: Especially during times of inflation, FIFO records your cost of goods sold (COGS) based on older, often cheaper inventory costs, which may result in higher-reported profits.
• Improves Order Fulfillment: FIFO helps ensure customers receive fresh, functional, or in-date products.
• Streamlines Processes: Clear stocking and picking rules make employee training and warehouse organization simpler.

Challenges and Considerations of FIFO

While FIFO is popular and effective, it’s not without challenges:

• Potential Tax Impact: In rising-price markets, FIFO can increase profits on paper, leading to higher tax liabilities.
• May Not Suit All Businesses: If your goods don’t deteriorate or become obsolete (like some high-tech products), FIFO may not make sense.
• Physical Storage Requirements: FIFO works best with well-organized storage systems—such as the “first-in” shelves at the front and newer stock at the back.
• Manual Errors: If employees don’t follow proper rotation or tracking, older stock can be left behind.

Best Practices for Implementing FIFO

Setting up FIFO effectively requires attention to both physical organization and record-keeping. Consider these practical tips:

1. Warehouse Organization

• Design shelves for easy access to oldest stock.
• Use clear labeling and signage to indicate receive dates.
• Regularly audit inventory to check for misplaced or expired items.

2. Employee Training

• Teach staff the value of FIFO for freshness, waste-reduction, and accuracy.
• Develop simple procedures for picking and restocking.

3. Inventory Management Software

• Use tools that support FIFO tracking and reporting.
• Set alerts for aging stock so nothing is forgotten.

4. Reconcile Regularly

• Periodically match physical inventory with records.
• Resolve discrepancies and investigate the cause (theft, spoilage, misplacement).

5. Monitor Cost Impacts

• Work with an accountant to understand how FIFO affects reporting, especially if prices fluctuate.
• Adjust business practices as needed to optimize profitability and compliance.

FIFO in Shipping and Cost Control

When considering shipping and logistics, FIFO remains critical—especially for goods with shelf-life concerns or regulatory requirements.

Shipping Best Practices with FIFO

• Arrange shipments so oldest stock is dispatched first.
• For perishable goods, coordinate with carriers to minimize delays.
• Use tracking systems to monitor lot numbers and movement dates.

Cost Tips

• FIFO can help avoid losses from obsolete or expired goods, saving on write-offs.
• Reducing waste translates into lower storage and insurance costs.
• Keep an eye on freight costs, especially if prioritized shipments (to avoid expiry) are necessary.

FIFO vs Other Inventory Methods

Businesses often compare FIFO with other inventory models. Understanding the differences helps in choosing the best approach.

Main Alternatives

• LIFO (Last-In, First-Out):
• Newest items are sold or used first.
• Can reduce paper profits (and taxes) when prices rise but may leave older inventory at risk of obsolescence.
• Weighted Average Cost:
• Costs of goods are averaged out, smoothing out fluctuations.

FIFO is usually preferred for industries where stock expires or becomes outdated, while LIFO might suit businesses in industries with lower risk of product decay.

Common Scenarios Where FIFO is Used

1. Grocery Stores: Ensuring older food is sold before fresher stock to prevent spoilage.
2. Pharmaceuticals: Dispensing medicine in the order it’s received to comply with regulations.
3. Manufacturing: Consuming raw materials in the order they arrive, preventing product defects.
4. Warehouses and Fulfillment Centers: Reducing risk of shipping outdated products.
5. Computer Science: Managing tasks, print jobs, or messages in the order they’re received.

Frequently Asked Questions (FAQs)

What is the main goal of using FIFO in inventory management?
The main goal is to ensure that products acquired or manufactured first are the first to be used or sold. This minimizes waste, reduces obsolescence, and ensures product quality for the customer.

Does FIFO affect how much tax a business pays?
Yes, it can. When prices rise over time, selling older (cheaper) inventory first means lower costs are recorded on profits reports, potentially increasing taxes. Consult with an accountant for personalized advice.

Is FIFO required by law?
In most countries, FIFO is not mandatory, but it may be strongly recommended for perishable or regulated goods. Some international accounting standards prefer it over LIFO.

Can FIFO be used with inventory management software?
Absolutely. Many modern inventory systems offer FIFO tracking, helping businesses automatically select oldest inventory when fulfilling orders and keeping accurate financial records.

What happens if FIFO is not followed correctly?
Failure to follow FIFO can result in outdated or expired inventory, increased waste, possible health/safety issues, inaccurate financial reporting, and potential legal troubles for regulated products.

Summary

FIFO—First-In, First-Out—is a cornerstone method in inventory and cost management, built on the simple principle of moving the oldest stock first. With clear benefits in waste reduction, accuracy, and simplified accounting, it remains popular, especially for businesses handling perishable or time-sensitive products. Carefully applying FIFO in storage, employee training, software tools, and shipping ensures your operation stays efficient, cost-effective, and compliant—leading to smarter business decisions and satisfied customers.
