Definition
A Stock-Keeping Unit (SKU) is a unique identifier assigned to each distinct product and service available for sale in a store or catalog. This identifier is often represented by a machine-readable bar code, facilitating easy tracking, inventory management, and sales analysis.
Functionality of SKUs
SKUs help businesses:
- Accurately track inventory levels.
- Identify product types and attributes.
- Monitor sales patterns.
- Streamline the restocking process.
- Enhance customer service by locating products quickly.
Types of SKUs
Manufacturer-Specific SKUs
Manufacturers might create SKUs that relate specifically to their product lines, embedding details such as size, color, and style directly into the SKU.
Store-Specific SKUs
Retailers generate their SKUs, ensuring they align with their inventory systems, which might vary significantly from manufacturer SKUs.
Special Considerations for SKUs
Consistency
Maintaining consistency in SKUs across the store helps in streamlined operations, avoiding conflicts and confusion during sales and inventory management.
Uniqueness
Each SKU at a retail level must be unique to distinguish between different products effectively.
Practical Examples
Example 1: A Clothing Store
In a clothing store, an SKU might look like “CLTH-RED-M-001,” where:
- CLTH: Clothing category
- RED: Red color
- M: Medium size
- 001: The first item in this category and combination
Example 2: A Grocery Store
For a grocery store, an SKU might be “GRY-APL-GRN-1KG-002,” indicating:
- GRY: Grocery category
- APL: Apple product
- GRN: Green color
- 1KG: Weight
- 002: The second item in this combination
Historical Context
The concept of SKUs revolutionized inventory management in the 1970s with the advent of computerized systems and barcodes allowing for rapid, accurate, and efficient tracking of products.
Applicability
Retail Industry
Retailers use SKUs to establish a systematic method for stock management, ensuring they meet customer demands without overstocking or understocking.
E-commerce
SKUs are crucial in e-commerce for tracking vast inventories spread over multiple warehouses and distribution centers, facilitating swift order fulfillment.
Comparisons with Related Terms
SKU vs. UPC (Universal Product Code)
While both SKUs and UPCs are vital for inventory tracking, UPCs are standardized and universal across manufacturers, whereas SKUs are unique to the specific retailer.
SKU vs. EAN (European Article Number)
EANs are similar to UPCs but primarily used outside the USA. SKUs, on the other hand, are specific to the retailer, providing more detailed internal controls and inventory management.
