What is ABC inventory classification?

The ABC inventory classification It is a method that allows us to prioritize the most important goods in a warehouse based on the value they provide and the benefits that result from it. In this way, items are classified not by volume or quantity, but by the significant economic contribution they make to the company.

This classification is based on the Pareto principle or the 80/20 rule, which indicates that with a 20% of sustained effort, it is possible to achieve an 80% in profits. In other words, effective product management leads to excellent results.

Advantages and Disadvantages of ABC Inventory Classification

The main advantage of ABC inventory classification is the way in which goods and their respective functions are organized and prioritized.

• The following are being expedited: operational processes and everything related to the warehouse becomes a more efficient, productive process without delays.

• Inventory management is improved. In other words, there is a greater knowledge about current and out-of-stock products, thereby avoiding unnecessary searches. 
• By clearly identifying the business's top-priority products, it is possible to focus on those that require a more advanced level of security and to determine which ones can minimize financial investment.

• Implementation costs: There are companies for which it may not be profitable.
• It does not take into account demand trends or external factors: Since it is based on historical data, it does not account for potential changes in demand. Nor does it take into account market factors, regulations, or price fluctuations.
• Focus on costs, not value: It focuses on costs rather than on the strategic value of the products.

• Risk of obsolescence: Category C products may become obsolete if they are not properly monitored.

What are the different types of ABC?

The ABC classification allows companies to prioritize their inventory management, focusing on the most important products (Category A) and ensuring that inventory levels are maintained at appropriate levels. Category C products, on the other hand, may require simpler management, as they have a much smaller impact on results.

To apply the ABC inventory classification, there are three categories that indicate storage priority based on their characteristics; let's see how they differ.

1. Class A

According to the basic storage rules, the A are associated with those products that are most commonly used or that have greater turnover and importance. In addition, the company has invested more in these assets, making them the largest source of cash revenue. It is best to conduct periodic inventory counts to calculate inventory turnover and to know how often we should restock certain products.

2. Class B

This includes products with an average turnover that, although they have a continuous flow On the market, they are less prominent than Class A products. Likewise, on store shelves, they are placed at a mid-level height where they do not occupy the top spots, but they are not completely hidden either.

3. Class C

Although there are a great many of these products, they are the ones that are less common on the market, the ones that customers rarely look for. They are located in the highest or hardest-to-reach areas. That is why they require constant monitoring to ensure they do not become obsolete inventory.

• • Category A: raw materials essential to the manufacturing process.

  • Category B: secondary materials or less important parts that are still necessary for the process.

  • Category C: materials that are of low value or that are used only occasionally in production.

3. Example at a pharmacy

• • Category A: High-cost drugs that are in high demand, such as treatments for chronic diseases.

  • Category B: drugs with moderate demand and average prices, such as common anti-inflammatory drugs.
