What is a SKU Number?

A SKU (Stock Keeping Unit) number is a unique alphanumeric code assigned to each product in a company’s inventory. These codes, typically ranging from 8 to 12 characters, help businesses manage inventory efficiently by including essential product details such as manufacturer, model, color, size, and style.

Key Features of SKU Numbers:

• Unique Identification: Each SKU is unique to a business and reflects attributes that are most relevant to their operations and customer inquiries.
• Inventory Management: SKUs streamline the organization, tracking, and management of inventory, helping businesses automate processes, prevent errors, and save time and money.
• Sales Analysis: SKUs provide insights into sales trends, customer preferences, and seasonal patterns, aiding in informed decision-making.
• Multi-Channel Tracking: SKUs are crucial for both physical stores and online retailers, ensuring accurate inventory tracking across various sales channels.

Where to Find SKU Numbers?

SKU (Stock Keeping Unit) numbers are essential for inventory management, sales tracking, and customer experience enhancement. Here are the common places where you can find SKU numbers:

Product Packaging:

• Manufacturers print SKU numbers on product packaging, typically on a small label or as a printed number. This helps in distinguishing items and ensuring proper inventory management.

Price Tags:

How to Create SKU Numbers?

Creating effective SKU numbers is essential for efficient inventory management and streamlined business operations. Here’s a step-by-step guide on how to create SKU numbers that work for your business:

Step 1: Start with a Top-Level Identifier

Begin your SKU number with a top-level identifier that represents the broadest product feature, such as the product category, department, or supplier. This helps to quickly identify the type of product at a glance.

• Example: For a clothing store, use “MT” for men’s t-shirts.

Step 2: Assign Unique Identifiers in the Middle Numbers

The middle section of your SKU should represent increasingly specific product features, such as size, color, or style. These unique identifiers help to differentiate between similar products within the same category.

• Example: “BLK” for black, “LRG” for large.

Step 3: Complete the SKU with a Sequential Number

Finish your SKU with a sequential number to indicate the order of products. This helps in tracking inventory levels and product movement.

• Example: “001” for the first item, “002” for the second.

Step 4: Input the SKUs into Your POS or Inventory Management System

Once you have created your SKU numbers, input them into your point of sale (POS) system or inventory management software. These systems automate the process of assigning and tracking SKUs, making it easier to manage your inventory and fulfill customer orders.

Step 5: Create SKU Barcodes

To further enhance inventory accuracy and efficiency, create barcodes for your SKU numbers. Barcodes enable quick and accurate product scanning, reducing the risk of human error and improving inventory management processes.

6 Tips for Managing SKU Numbers

Effective SKU management is vital for businesses aiming to streamline their inventory, enhance sales tracking, and inform strategic decisions. By consistently creating, tracking, and updating SKUs, you can refine your inventory levels and elevate your profitability.

Here are six pivotal tips for managing your SKU numbers effectively:

1. Keep it Consistent

Adhering to a consistent structure and format for all SKUs is crucial for efficient inventory management. Ensure your SKU numbers are standardized, simplifying their comprehension and tracking. This consistency minimizes confusion and errors in managing your product inventory.

2. Never Use Zeros or Special Characters

Avoiding zeros and special characters in SKU numbers is crucial. Zeros might be overlooked or omitted by employees or retail software, leading to errors. Special characters like !, @, or & can also cause compatibility issues with certain systems. Opt for alphanumeric characters for seamless SKU management.

3. Define Popular Product Features

Integrate popular product features into your SKU numbers to aid your sales team in identifying and promoting in-demand items. By tracking attributes such as size, color, and brand, you ensure the right mix of products to meet customer preferences and boost sales.

4. Make Regular SKU Updates

Keeping your SKUs current is essential as your product offerings change. Regularly review and update your SKU numbers to reflect changes in product features, discontinuations, or new inventory additions. This proactive approach ensures accurate inventory levels and prevents discrepancies between records and stock.

5. Use SKU Data to Improve Sales

Utilize SKU data to inform business decisions. Analyze sales data to pinpoint top-performing products and prioritize them for promotions or discounts. Inventory data can help calculate reorder points and prevent stockouts. Leveraging SKU data optimizes sales strategies and fosters growth.

6. Monitor SKU Performance

Continuously monitor SKU performance to stay abreast of sales trends and inventory levels. Tracking which products excel and which underperform allows for data-driven inventory management adjustments. This ongoing evaluation identifies opportunities for enhancement and ensures customer demand is met.

5 Benefits of Using SKUs

Stock Keeping Units (SKUs) play a crucial role in various aspects of business operations, offering numerous advantages. Here are five significant benefits of using SKUs:

1. Improved Inventory Management

Using SKUs allows businesses to effectively track and manage their inventory. Each SKU represents a unique product, making it easier to identify and locate items within a warehouse or store. This detailed tracking helps in:

• Real-Time Inventory Updates: Knowing the exact number of items in stock at any given time.
• Minimized Stockouts and Overstocks: Ensuring that the right amount of inventory is maintained to meet demand without excessive surplus.
• Streamlined Reordering Processes: Facilitating automatic reordering based on inventory levels, reducing the risk of running out of stock.

2. Better Sales Tracking

SKUs enable precise sales tracking, allowing businesses to monitor which products are selling well and which are not. This insight helps in:

• Sales Analysis: Identifying sales trends and patterns to understand customer preferences.
• Informed Decision-Making: Making data-driven decisions on product promotions, discontinuations, and inventory adjustments.
• Revenue Management: Tracking revenue streams more accurately, aiding in financial planning and forecasting.

3. Increased Efficiency

Implementing SKUs increases operational efficiency across various business processes. This includes:

5 Challenges of Using SKUs

While Stock Keeping Units (SKUs) offer numerous benefits for inventory management and sales tracking, they also come with their own set of challenges. Here are five significant challenges of using SKUs, along with potential solutions to address them:

1. Difficulty in Generating Unique SKUs

Creating unique SKUs for each product can be complex, especially as the number of products grows. Duplicates or overly complicated SKUs can lead to confusion and errors.

Solution: Develop a standardized SKU generation system that incorporates key product attributes such as category, brand, size, and color. Use a consistent format and automated tools to generate SKUs to ensure uniqueness and simplicity.

2. Keeping SKU Information Up-to-Date

Maintaining accurate and current SKU information is essential but can be time-consuming. Outdated information can lead to inventory inaccuracies and operational inefficiencies.

Solution: Implement an integrated inventory management system that updates SKU information in real time. Regular audits and automated alerts for discrepancies can help ensure that SKU data remains accurate and up-to-date.

3. Human Error

Human errors in SKU entry or management can result in significant issues, such as incorrect inventory counts, misplaced products, or erroneous sales data.

Solution: Minimize manual data entry by using barcode scanners and automated systems. Provide comprehensive training for employees on how to handle SKUs correctly and implement regular checks to catch and correct errors promptly.

4. Integrating with Other Systems

Integrating SKU data with other systems such as ERP (Enterprise Resource Planning), CRM (Customer Relationship Management), or e-commerce platforms can be challenging and may lead to data silos or inconsistencies.

Solution: Use middleware or integration platforms that facilitate seamless data exchange between different systems. Ensure all systems follow a consistent data format and conduct regular tests to verify the accuracy of integrated data.

5. Inadequate Employee Training

Insufficient training can lead to improper handling of SKUs, resulting in errors and inefficiencies in inventory management and sales tracking.

Solution: Develop a comprehensive training program that covers all aspects of SKU management, from creation to maintenance. Regular refresher courses and updates on new practices or technologies can help employees stay proficient in managing SKUs.

SKU vs UPC: What’s the Difference?

Managing inventory and identifying products involve both SKUs (Stock Keeping Units) and UPCs (Universal Product Codes). Though they may seem similar, they have distinct differences that are crucial for businesses to understand.

Here’s the key differences:

SKU (Stock Keeping Unit)

• Definition: Unique codes created internally by companies to manage their inventory.
• Format: Alphanumeric, typically ranging from 8 to 12 characters.
• Assignment: Created by each company and may include details like color, size, style, and other attributes.
• Consistency: Unique to each retailer; the same product can have different SKUs at different stores.
• Purpose: Primarily for internal inventory management and tracking.
• Barcodes: May have associated barcodes for internal use.

UPC (Universal Product Code)

• Definition: Standardized 12-digit numeric codes used universally to identify products.
• Format: Numeric only, exactly 12 digits long.
• Assignment: Issued by the Global Standards Organization (GS1) to manufacturers. The first 6-9 digits identify the manufacturer, and the remaining digits are specific to the product.
• Consistency: Consistent across all retailers; the same product has the same UPC regardless of the seller.
• Purpose: Universal product identification for use at the point of sale.
• Barcodes: Always features a scannable barcode that is used by all retailers and distributors.

5 Common Mistakes to Avoid with SKU Numbers

Creating an effective SKU system is vital for efficient inventory management and error prevention. Many businesses, however, fall into common traps when setting up and managing their SKUs. By recognizing and sidestepping these errors, you can enhance your inventory tracking and increase profitability.

1. Overcomplicating SKUs

Businesses often err by crafting overly complex SKU structures. It’s crucial to include relevant product details, but using too many characters or complex naming can cause confusion and mistakes. SKUs should be concise, typically ranging from 8 to 12 characters. A simple and logical SKU system ensures easy management and precise tracking.

2. Not Updating SKUs

As products change, so should your SKUs. Not updating them can lead to incorrect inventory levels and stock management issues. Nearly 60% of retail businesses struggle with supply chain visibility, often due to outdated SKUs. Regularly reviewing and updating your SKUs helps maintain a clear, current inventory system.

3. Using Manufacturer’s SKUs

Using the manufacturer’s SKU might seem easy, but creating your own is better. It aids in internal tracking and avoids confusion if you stock products from various manufacturers. Your own SKU system allows for specific product attributes and a consistent naming convention across your inventory.

4. Lack of SKU Hierarchy

A structured SKU system needs a clear hierarchy, with key product attributes first. This includes details like manufacturer/supplier, department, and item size/type/brand. Without a logical hierarchy, sorting and identifying products becomes hard, leading to inventory management inefficiencies.

5. Not Linking SKUs to UPCs

SKUs are for internal use, but linking them to UPCs is essential. UPCs are standardized identifiers crucial for selling through marketplaces and integrating with external systems. Connecting SKUs to UPCs ensures product cross-referencing and accurate inventory levels across sales channels.

SKU Number Examples

To grasp how SKU numbers work in retail, e-commerce, and manufacturing, let’s delve into real-world examples. These examples show how businesses tailor SKU numbers to their products and needs. They provide a clear view of SKU naming conventions across industries.

Retail

In retail, SKU numbers often include details like product category, brand, style, color, and size. For instance, a clothing retailer might use the SKU TS-BX-001-BLK-M for a medium-sized black t-shirt from Brand X. This breaks down as follows:

• TS: T-shirt (product category)
• BX: Brand X (brand)
• 001: Style number (unique identifier)
• BLK: Black (color)
• M: Medium (size)

E-commerce

E-commerce platforms use SKU numbers that detail product type, brand, model, and variant. An online retailer might assign the SKU PHN-BY-S20-64S to a 64GB silver smartphone from Brand Y. This SKU can be interpreted as:

• PHN: Phone (product type)
• BY: Brand Y (brand)
• S20: Model name (unique identifier)
• 64S: 64GB, Silver (variant)

Manufacturing

Manufacturers create SKU numbers that include part type, vehicle make, model, year, and variant. For example, a manufacturer might use the SKU BPF-HON-CIV-20-001 for a front brake pad set for a 2020 Honda Civic. This SKU breaks down as follows:

• BPF: Brake Pad, Front (part type)
• HON: Honda (vehicle make)
• CIV: Civic (model)
• 20: 2020 (year)
• 001: Variant number (unique identifier)

Conclusion

Implementing an SKU system is vital for every business aiming to enhance efficiency and profitability. SKU numbers streamline inventory management, enable precise sales tracking, improve customer experiences, and support better supply chain management.

To maximize these benefits, ensure your SKUs are consistently formatted, regularly updated, and integrated with your inventory management systems.

Start today by evaluating your current inventory practices and identifying areas where SKUs can make a difference. As you embrace this powerful tool, you’ll not only optimize operations but also set the stage for sustained business growth.
