Decoding SKU Numbers: A Comprehensive Guide for eCommerce Businesses

Introduction: The Backbone of Inventory Management

In the fast-paced world of eCommerce, efficient inventory management is crucial for success. As businesses grow and orders multiply, keeping track of individual items becomes increasingly challenging. This is where Stock Keeping Units (SKUs) come into play. SKU numbers are the unsung heroes of inventory management, providing a systematic way to organize and track products. In this comprehensive guide, we'll explore what SKU numbers are, how they work, and why they're essential for your eCommerce business.

What is an SKU Number?

SKU stands for Stock Keeping Unit. It's an alphanumeric code assigned to products by retailers to identify and track individual items in their inventory. SKUs represent various product characteristics such as model, size, brand, color, and item location.

How Does an SKU Work?

SKUs function as a unique identifier for each product variant in your inventory. While there's no universal standard for creating SKUs, the basic principle remains the same: retailers assign these codes to quickly and easily identify items based on specific attributes. The information in an SKU is typically ordered from the most important features to the least important ones that distinguish different products.

For example, two T-shirts from the same brand with identical styles but different colors might have similar SKUs, with only one character differentiating the color variation.

The Importance of SKUs in eCommerce

SKU management is crucial for online retailers, order fulfillment centers, and warehouse managers. Here are some key reasons why SKUs are important:

• Inventory tracking and management
• Efficient order fulfillment
• Easy product information lookup
• Quick product location
• Streamlined 3PL processes
• Improved business decision-making

SKU vs. UPC: Understanding the Difference

While both SKUs and Universal Product Codes (UPCs) contain important product information, they serve different purposes. Here are the key differences:

• Length: SKUs can be any length, while UPCs are always 12 digits
• Creation: Retailers create SKUs; GS-1 and manufacturers create UPCs
• Composition: SKUs are alphanumeric; UPCs are numeric only
• Usage: SKUs are used internally by retailers; UPCs are used universally throughout the supply chain
• Information: SKUs contain retailer-specific information; UPCs identify manufacturers and producers

Creating an Effective SKU System

While there's no standardized method for creating SKUs, it's essential to develop a system that is easily understandable by you, your employees, and vendors. Here are some best practices for creating an effective SKU system:

1. Make SKUs easily understandable
2. Avoid starting SKUs with zero
3. Establish a consistent formula
4. Use top-level identifiers at the beginning
5. Include unique identifiers in the middle
6. End with sequential numbers

Example SKU: M-S-P-0012 (Men's Sportswear, Purple, Item 0012)

8 Ways Optimized SKUs Can Improve Your Business Performance

An efficient SKU system can significantly enhance your eCommerce operations. Here are eight ways optimized SKUs can boost your business performance:

1. Track and Improve Sales

By analyzing SKU trends, you can identify your most popular products and adjust your inventory accordingly. This data-driven approach helps improve sales and boost profits by ensuring you stock the items your customers want most.

2. Enhance Merchant-Vendor Communications

SKUs facilitate smoother communication with vendors. You can use SKU data for sales forecasts and set expectations for anticipated product demand, ensuring your suppliers can meet your requirements and reducing the risk of late shipments.

3. Avoid Stockouts and Boost Customer Satisfaction

With SKUs, you can set reorder points that trigger alerts when inventory reaches a certain level. This proactive approach helps prevent stockouts, ensuring customers can always find the products they want and improving overall satisfaction.

4. Speed Up Inventory Tracking

SKUs streamline the inventory tracking process, making it easier to conduct accurate stock counts. This efficiency reduces disruptions to business operations and provides a clear picture of available merchandise.

5. Improve E-store Search Functionality

Customers often search for specific product details or SKUs when looking for items. By incorporating SKUs into your product listings, you increase the chances of your store appearing in search results, potentially leading to more sales.

6. Reduce Errors, Theft, and Damage

SKUs help you track items from the moment they arrive in your warehouse until they reach the customer. This comprehensive tracking reduces the risk of errors, theft, or damage, saving you money and improving overall efficiency.

7. Enhance Marketing and Remarketing Efforts

SKU data can inform your marketing strategies. By identifying popular products or trends, you can create targeted ads and remarketing campaigns to reach potential customers more effectively.

8. Streamline Third-Party Fulfillment

If you work with third-party fulfillment providers, SKUs are essential for smooth operations. They enable automatic inventory syncing, order tracking, and real-time inventory counts, improving the overall fulfillment process.

How to Read SKU Numbers

Reading SKU numbers is an essential skill for anyone involved in inventory management. Here's a step-by-step guide on how to interpret SKU numbers:

1. Identify the top-level category: The first characters usually represent the broadest category, such as department or product type.
2. Look for subcategories: The next set of characters often denotes more specific product attributes like size, color, or style.
3. Check for unique identifiers: These may include brand codes or specific product features.
4. Note the sequential number: The final digits typically indicate the item's place in the product line or inventory sequence.

Remember, each company may have its own SKU system, so familiarize yourself with your specific organization's approach.

What Does an SKU Number Look Like?

SKU numbers can vary in appearance depending on the retailer's system, but they generally follow a consistent format within a single organization. Here are some examples of what SKU numbers might look like:

• ABC-1234-M-BLU (Product line - Item number - Size - Color)
• WM-TSH-RD-001 (Department - Product type - Color - Sequential number)
• ELEC-TV-55-4K-001 (Category - Subcategory - Size - Feature - Sequential number)

These examples demonstrate how SKUs can be tailored to represent different product attributes while maintaining a logical structure.

What Does an SKU Number Mean?

An SKU number is more than just a random string of characters; it's a meaningful code that conveys important information about a product. Here's what different parts of an SKU might represent:

• Product category or department
• Subcategory or product type
• Brand or manufacturer
• Size or dimensions
• Color or finish
• Specific features or attributes
• Variant within a product line
• Location in the warehouse

By understanding what each part of an SKU means, you can quickly glean important information about a product without needing to look up its full description.
