What is the Full Form of SKU?

SKU is the abbreviated form of Stock Keeping Unit. This term is widely used in inventory management and retail operations to uniquely identify and track products.

What is Stock Keeping Unit?

A Stock Keeping Unit, commonly known as SKU, is a distinct alphanumeric code assigned to a product by a company for inventory management and sales tracking purposes. It serves as a unique identifier for each product variant, allowing businesses to monitor stock levels, analyze sales patterns, and streamline their supply chain operations.

Origin and Development of Stock Keeping Unit

The concept of Stock Keeping Units has been around for decades, evolving alongside the growth of retail and inventory management systems. As businesses expanded and product varieties increased, the need for a standardized method to track individual items became crucial. The development of SKUs has been closely tied to the advancement of technology in retail, from early barcode systems to modern digital inventory management solutions.

How does Stock Keeping Unit work?

Stock Keeping Units work by assigning a unique code to each product variant. This code typically consists of a combination of letters and numbers that represent various product attributes. Here's how SKUs function:

  1. Code Creation: Companies develop a system for generating SKUs based on product characteristics such as brand, size, color, and model number.
  2. Product Identification: Each product variant receives a unique SKU.
  3. Database Integration: SKUs are entered into inventory management systems and linked to product information.
  4. Tracking: As products move through the supply chain, their SKUs are scanned or entered to update inventory levels and sales data.
  5. Analysis: Businesses use SKU data to analyze product performance, manage stock levels, and make informed decisions about purchasing and pricing.

Functions of Stock Keeping Unit

Stock Keeping Units serve several critical functions in retail and inventory management:

  • Unique Product Identification: SKUs ensure that each product variant can be distinguished from others, even if the differences are subtle.
