Understanding Stock Keeping Units (SKUs)

A Stock Keeping Unit (SKU) is a unique code used to identify each product in inventory. It helps in tracking and managing stock. The concept of SKUs began with simple manual coding systems. As technology advanced, SKUs evolved to include barcodes and digital tracking. Today, SKUs play a key role in automated inventory systems, enhancing accuracy and efficiency. An SKU is a specific alphanumeric code assigned to each product. It distinguishes one item from another. This code is crucial for organizing inventory. SKUs are vital for efficient inventory management. They help businesses track product quantities, manage stock levels, and streamline order fulfillment. Proper use of SKUs ensures accurate inventory records and reduces errors.

Components of a SKU

Knowing “what is SKU” helps in managing “SKU inventory” effectively. Each SKU is designed to simplify product tracking and inventory management. By using a well-structured SKU format, businesses can streamline their operations and improve efficiency.

Structure and Format

A SKU, or Stock Keeping Unit, is a unique identifier for each product in your inventory. It helps track and manage stock efficiently. SKUs usually consist of a combination of letters and numbers. The format can vary by business but typically includes a structured pattern. For example, an SKU might be “123-AB45,” where “123” could denote the product category, “AB” could represent the supplier, and “45” could indicate a specific product variant.

Information Encoded in SKUs

SKUs encode key information about a product. They often include:

• Product Category – Identifies the type of product (e.g., electronics, clothing).
• Brand or Supplier – Shows the brand or supplier of the product.
• Variant Details – Provides specifics like size, color, or model.
• Location or Batch Information – This may include warehouse location or batch number for tracking.

This encoding helps in managing inventory by simplifying the process of tracking and locating items. For example, if a SKU ends with “BLK,” it might indicate a black color variant.

Examples of Different SKU Formats

• Basic Format – “001-RED-S” – where “001” is the product category, “RED” is the color, and “S” is the size.
• Extended Format – “123-ABC-45-XX” – where “123” denotes the category, “ABC” is the brand, “45” is the product model, and “XX” could represent additional attributes.
• Custom Format – “ELECTRONICS-XYZ-2024” – where “ELECTRONICS” is the category, “XYZ” is the brand or model, and “2024” is the year of manufacture or a specific batch.

Types of SKUs

Manufacturer SKUs

Manufacturer SKUs are codes assigned by the product’s manufacturer. These SKUs are used to identify and track products through the supply chain. They are often unique to each manufacturer and can help with inventory management and ordering. For example, a manufacturer’s SKU might look like “AB1234.” It typically includes details about the product’s category, type, and sometimes its specifications.

Retailer SKUs

Retailer SKUs are codes created by the retailer for their own inventory management. They may differ from the manufacturer’s SKUs and are designed to simplify tracking and sales processes within the store or online platform. Retailer SKUs help in organizing products and managing stock more effectively. They usually include a combination of letters and numbers that make sense to the retailer’s system. For example, a retailer SKU might be “RT5678.”

Custom SKUs

Custom SKUs are tailored to the specific needs of a business. These SKUs are created to fit a company’s unique inventory and sales requirements. Custom SKUs can include information like the product category, size, color, or any other relevant detail that helps in tracking. They are especially useful for businesses with diverse product lines and need precise inventory control. An example could be “CS-LG-RED,” indicating a large red item in a custom system.

Master SKUs

Master SKUs are used to track a product at a high level of aggregation. They are often used for managing inventory across different locations or channels. A master SKU can represent a product family or a collection of similar items, making it easier to manage large inventories. For example, “MSK-9000” might represent a product line with various sizes and colors.

Importance of SKUs in Business Operations

Understanding “What is SKU” and the importance it holds in business operations plays an important part in efficient inventory management, order fulfillment, sales analysis, and product identification. Let’s understand the following terms.
