Understanding SKU Management on Amazon

SKUs are alphanumeric codes assigned to individual products in your Amazon inventory. These codes are vital in inventory management, order fulfillment, and customer experience. By assigning unique SKUs to your products, you can easily track inventory levels, identify specific items, and streamline order processing. SKUs also facilitate effective communication and coordination with Amazon’s fulfillment centers, ensuring smooth logistics and timely deliveries.

Key Challenges and Common Issues in SKU Management

While SKUs offer numerous benefits, their management can pose challenges for sellers. Common issues include SKU proliferation, inconsistent naming conventions, and difficulties in managing diverse product lines. Without effective SKU management, you may face inventory errors, delays in order processing, and customer dissatisfaction. However, implementing best practices and strategies can overcome these challenges and optimize your Amazon business.

Best Practices for Effective SKU Management

To create an effective SKU management system, choosing the right SKUs for your Amazon store is essential. Consider the following strategies:

Importance of Aligning SKUs with Target Audience and Market Demand

Research your target audience and market demand to identify popular product categories and trends. Align your SKUs with these insights to increase the likelihood of sales and profitability. By offering products that are in high demand, you can attract more customers and maximize your revenue potential.

Strategies for Selecting Profitable and In-Demand SKUs

Conduct thorough market research to identify profitable and in-demand products. Look for gaps in the market or niche opportunities that align with your business goals. Choose SKUs that have a good profit margin and consider factors like competition, pricing, and consumer demand to make informed decisions.

Considerations for SKU Standardization and Naming Conventions

Standardize your SKU naming conventions to ensure consistency and ease of management. Incorporate relevant information such as brand, product category, and variations (e.g., size, color) into your SKUs. This standardization simplifies inventory tracking and minimizes errors in order processing.

ASIN vs SKU: What’s the Difference?


If you’re already selling on Amazon or you’ve been looking into it, you’ve probably come across the ASIN acronym too. This is often used in tandem with SKUs, so it can get confusing about what each one is for.

While SKUs are codes for sellers to keep track of their products, ASINs (which stands for Amazon Stock Identifier Numbers) are unique codes for products sent into Amazon’s warehouse.

Basically, an ASIN is Amazon’s version of an SKU and it helps them keep track of merchandise instead of leaving it up to sellers.

How to Create Seller SKUs on Amazon

At Urtasker, we encourage our clients to create their own SKUs for their products. It makes selling products and managing inventory that much easier. Luckily, creating unique SKU codes is fairly simple. In fact, sellers have two options:

  • Create SKU codes manually
  • Use an SKU generator or point-of-sale software

How to Create Your Own SKUs

Amazon sellers that choose to create their own SKUs (that is, without the help of an SKU generator) have more control over their codes and what identifiers go into them. If you decide to create your own, you might want to include letters and numbers that represent:

  • The product’s supplier or manufacturer
  • The type of item (for example, if you’re selling books, you might have the letters BK in there as an identifier)
  • The date you sent the products to Amazon’s warehouse
  • The condition of your product (for example, if the product is new, you might include the letters NW in your SKU to identify that)
  • The number of the product in a batch

How to Use an SKU Generator to Create SKUs

If you don’t want to create your own SKUs, you can use Amazon’s “SKU Generator within WP-Lister”. This can be accessed through the Amazon tools tab on Seller Central.

There are two ways Amazon’s generator picks unique codes for products:

  1. SKUs based on the product’s title
  2. SKUs based on the product’s attributes and details

Sellers can choose which variant they want to use for their product. Bear in mind that all lowercase SKUs are automatically converted into uppercase.

Optimizing SKU Attributes and Information

Accurate and comprehensive SKU data is crucial for effective SKU management. Consider the following practices:

Importance of Accurate and Comprehensive SKU Data

Ensure that each SKU has accurate and up-to-date information, including product descriptions, features, and specifications. This data helps customers make informed purchase decisions and improves the overall shopping experience.

Adding Relevant Attributes for Enhanced Visibility and Searchability

Leverage Amazon’s attribute system to add relevant attributes to your SKUs. This includes information like size, color, material, and other product-specific details. By providing detailed attributes, you enhance the visibility of your products in search results, making them more discoverable to potential buyers.

Utilizing SKU-Specific Information to Improve Customer Experience

Consider including SKU-specific information in

your product listings to address customer queries and provide additional details. This may include usage instructions, care guidelines, or warranty information. By anticipating and addressing customer needs, you can enhance their overall experience and build trust in your brand.

Streamlining SKU Organization and Inventory Management

Efficient organization and management of SKUs are essential for smooth operations. Consider the following practices:

Grouping SKUs by Similarities to Simplify Management

Organize your SKUs into logical groups based on similarities such as product category, brand, or variations. This grouping simplifies inventory management and facilitates faster product identification and tracking.

Setting SKU-Specific Reorder Points to Ensure Timely Replenishment

Establish SKU-specific reorder points based on sales velocity and lead time. This ensures that you replenish your inventory in a timely manner, avoiding stockouts and meeting customer demand consistently.

Techniques for Removing Unpopular or Low-Performing SKUs

Regularly analyze your SKU performance metrics, such as sales data and profitability. Identify SKUs that are underperforming or have low demand and consider removing them from your inventory. By streamlining your SKU selection, you can focus on high-performing products and optimize your sales potential.

Leveraging Technology for SKU Management

Harnessing technology can greatly simplify SKU management. Consider the following practices:

Exploring Inventory Management Software and Tools

Utilize inventory management software or tools specifically designed for Amazon sellers. These solutions offer features such as SKU tracking, order processing, and inventory forecasting, streamlining your operations and reducing manual errors.

Utilizing Data Analytics for SKU Performance Analysis

Leverage data analytics to gain insights into your SKU performance. Analyze key metrics such as sales velocity, inventory turnover, and profit margin to identify trends and make data-driven decisions. Data analytics empowers you to optimize your SKU selection and inventory management strategies for increased profitability.

Automation and Integration Options for Efficient SKU Management

Explore automation and integration options to streamline SKU management tasks. For example, you can integrate your inventory management software with your Amazon seller account to automate inventory updates and order processing. This integration minimizes manual effort, reduces the risk of errors, and enhances efficiency.

Monitoring and Adjusting SKU Strategies

Continuous monitoring and adjustment of SKU strategies are crucial for long-term success. Consider the following practices:

Tracking SKU Performance Metrics and Sales Ratios

Regularly monitor key SKU performance metrics, such as sales volume, conversion rates, and customer reviews. Analyze these metrics to identify top-performing SKUs and areas for improvement. Additionally, track sales ratios to ensure a healthy mix of high-demand and low-demand products in your inventory.

Reviewing SKU Turnover and Adjusting Inventory Accordingly

Assess your SKU turnover rate to determine the optimal quantity of each SKU in your inventory. High-turnover SKUs may require higher stock levels, while low-turnover SKUs may need reduced quantities. Regularly adjust your inventory based on SKU turnover to optimize your cash flow and minimize excess inventory.

Adapting SKU Strategies Based on Changing Market Trends and Customer Demand

Stay updated with market trends and monitor customer demand for your products. Adjust your SKU strategies accordingly, introducing new SKUs or discontinuing underperforming ones. By staying agile and responsive to market dynamics, you can maintain a competitive edge and maximize your sales potential.
