What is a SKU Catalog?

A SKU catalog is a comprehensive and organized list of all the individual items a business sells, each identified by a unique SKU number. SKUs (stock-keeping units) are alphanumeric codes assigned to products to differentiate them based on various attributes such as size, color, and style.

The SKU catalog serves several critical functions in business operations:

• Inventory management — Tracking and managing inventory levels with the SKU catalog ensures the business can maintain optimal stock levels, avoid overstocking or stockouts, and streamline reordering processes.
• Sales and order processing — It facilitates accurate and efficient order processing by allowing quick identification and retrieval of products during sales transactions, thereby improving customer satisfaction and reducing errors.
• Data analysis and reporting — Businesses use the SKU catalog to analyze sales patterns, identify best-selling items, and make informed decisions about product assortment, pricing strategies, and marketing efforts.
• Supply chain coordination — Clear and consistent product information makes it easier to coordinate with suppliers and distributors, aiding in the smooth flow of goods from production to final sale.

A well-maintained SKU catalog is essential for effective inventory control, operational efficiency, and strategic decision-making. This is especially the case in retail, ecommerce, and manufacturing industries, where hundreds or thousands of physical products are sold and restocked frequently.

Note: A SKU catalog is different from a product catalog. While product catalogs represent each product the company sells, SKUs uniquely identify the variations within each product. For example, a t-shirt (product) might have 5 separate SKUs for sizes S, M, L, XL, and XXL.

Importance of SKU Catalogs in Inventory Management

Inventory management is perhaps the most essential use case for SKU catalogs. Within the inventory management system, the SKU catalog is linked to each product’s on-hand quantity, location, and movement history. This information gives businesses real-time visibility into inventory, allowing for timely decisions on procurement, storage, and order fulfillment.

There are several roles the SKU catalog plays in efficient inventory management processes:

Accurate inventory tracking

SKUs provide a unique identifier for each product, which enables precise tracking of inventory levels. That way, the business can maintain an accurate count of their stock, reducing the risk of overstocking or stockouts.

The catalog defines the attributes of each SKU, such as size, color, and style. This information is crucial in identifying and organizing similar items and avoiding duplicate SKUs.

The SKU catalog also plays a crucial role in preventing stock discrepancies and errors that can result in lost sales or excess holding costs. By providing a unique identifier for each product variant, it minimizes confusion and human errors that may arise from using generic product names or codes.

Efficient order fulfillment

With a well-organized SKU system, businesses can quickly locate and retrieve products during the order fulfillment process. This reduces the time taken to process orders and minimizes errors, leading to higher customer satisfaction and loyalty.

Shrinkage reduction

Effective SKU management helps identify and address inventory shrinkage, which can occur due to theft, damage, or administrative errors. By monitoring SKUs, businesses can detect discrepancies between recorded and actual stock levels, enabling them to take swift corrective actions.

Streamlined reordering processes

SKUs allow businesses to set customized reorder points for each product based on their sales data and inventory turnover rates. This ensures that popular items are always in stock, while slow-moving items are reordered less frequently, optimizing inventory costs and storage space.

When the master catalog accurately represents the organization’s products, it can also serve as a reference for purchasing and sourcing decisions. By using SKUs consistently across all departments, businesses minimize confusion, delays, and errors in communication between different teams.

Data-driven decision-making

SKUs facilitate detailed reporting and analysis of sales trends and product performance. Businesses can use SKU-level data to forecast demand, plan promotions, and make informed decisions about product assortment and pricing strategies.

Let’s say a business is considering discontinuing a particular product line. By looking at the SKU-level data, they may discover that while overall sales for that product are low, certain variants within the product line have consistently high demand.

Enhanced customer experience

In both ecommerce and physical retail settings, SKUs enable customer service teams to quickly locate products, check stock levels, and provide accurate information to customers. This leads to a better shopping experience and increased customer satisfaction.

For manufacturing companies, product SKUs also help streamline the production process by providing a standardized way to identify and track raw materials, components, and finished goods. For customers, that means consistent quality, faster delivery times, and fewer errors in fulfilling orders.

The SKU catalog can even help businesses before the sale happens. By incorporating SKUs into their sales quoting process, businesses can provide accurate quotes based on the correct product and pricing information, leading to more efficient and profitable sales cycles.

Benefits of SKU Catalogs 

The SKU catalog is a simple master list that acts as the foundation for product-related business processes. The product information within it helps them streamline their production, delivery, and supply chain processes. They also help businesses optimize their SKU count and product mix through SKU rationalization.

Because of this, a well-maintained SKU catalog offers several benefits to businesses:

• Better inventory management and control 
• Improved collaboration across departments 
• Reduced stock discrepancies and errors 
• Streamlined ordering and reordering processes 
• Informed decision-making based on accurate data  
• Enhanced customer satisfaction and loyalty 
• Higher profitability

These benefits result from the fact that a SKU catalog is the guiding force for all activities related to products. It’s the central repository for all product-related information, providing consistency and accuracy across the supply chain.

SKU Catalog Elements 

While your SKU catalog might have additional elements specific to your business, a typical SKU catalog contains the following information:

SKU number

This is the unique alphanumeric code assigned to each product. It typically includes a combination of letters and numbers that denote specific product attributes such as type, size, color, and brand.

An example of a product SKU number for a black, size medium, t-shirt might be BLK-M-TS-123.

Product description

In this section, there will be a detailed description of the product, including its features, specifications, and any other relevant information that helps in identifying the product and differentiating it from similar items.

Product specifications

Specifications are the specific characteristics of the product, such as size, color, weight, material, etc. These attributes are often encoded in the SKU number to allow for quick identification and differentiation of products.

Category

Product categories group similar items together for easier organization and management. These can be broad categories like “apparel” or more specific ones like “men’s t-shirts.” Categorizing products helps in creating logical product groupings and optimizing inventory processes.

Vendor information

This section includes details about the manufacturer or supplier of the product, such as brand name, contact information, and any other relevant data for sourcing and procurement purposes.

Cost price

The cost price is the amount paid to acquire the product from the vendor. It helps retailers and sellers calculate their margins, assess their profitability, and determine their pricing strategies.

Selling price

This is the price at which the product is sold to customers. A well-maintained SKU catalog tracks this information alongside the cost price to provide accurate profitability analysis.

Inventory levels

Inventory levels tell you the current quantity of the product in inventory. This helps in inventory management, ensuring that businesses can maintain optimal stock levels and avoid overstocking or stockouts.

Reorder point

The reorder point is the inventory level at which a new order should be placed to replenish stock. With modern inventory management software, crossing this point automatically triggers a reorder. This helps prevent stockouts and ensures that popular items are always available.

Lead time

Lead time refers to the amount of time it takes for a product to be delivered from the point of order. This information is crucial in forecasting and planning inventory levels, as well as setting customer expectations for delivery times. The reorder point should always be optimized according to lead time and demand patterns to avoid stockouts.

Images

Product images make it easy to visually identify products and are especially useful for ecommerce businesses. They also help fulfillment teams locate and pick the correct product from a physical warehouse or store.

Best Practices for Managing SKU Catalogs

When it comes to SKU catalog management, you can’t just come up with random numbers and descriptions for your products. To ensure consistency, accuracy, and efficiency, you need standardization, structure, and a clear set of rules.

Here are some best practices for managing SKU catalogs:

Establish a standardized SKU numbering system.

This is what makes it easy to identify and differentiate products. A standardized system ensures that all team members use the same format and eliminates confusion.

For example, instead of using random numbers, you can use a structured system where the first few digits represent the product category, the next digits denote size/quantity, and the last few digits are for color or other attributes.

Using the black t-shirt example from above, let’s say you have four size options — S, M, L, and XL.

• Small: BLK-TS-S-123
• Medium: BLK-TS-M-123
• Large: BLK-TS-L-123
• Extra large: BLK-TS-XL-123

That way, it’s easy to read “BLK = black,” TS = t-shirt,” and “S, M, L, and XL = sizes.”

Note: The number “123” represents a unique number for each product within that category and size. For another product, the number would be different.

Regularly review and update your SKU catalog.

Products change, new ones are added, and old ones may become obsolete. Set a schedule for reviewing and updating your SKU catalog to ensure it remains accurate and relevant.

During an audit, look at all the following areas for errors or known changes:

• Descriptions
• Specifications
• Cost and selling prices
• Inventory levels
• Lead times

Keep your categories simple and consistent.

Avoid creating too many subcategories. Stick to broad ones that encompass multiple products, and make sure everyone in the organization uses these same categories consistently.

For instance, “apparel” is a broad category, while “men’s t-shirts” is more specific. You can further break it down by size or color, but avoid creating too many layers that can make it confusing to categorize products (e.g., an additional category for “black t-shirts,” when that should just be a filtering option).

Utilize inventory management software.

You need a centralized system that makes it easy to track and manage your SKU catalog. Manually tracking inventory levels, reorder points, and lead times is remarkably difficult and prone to human error.

Inventory management software automates these processes and provides real-time data for better decision-making. It also allows for customization of fields and reports according to your business needs.

Set up role-based permissions.

Not everyone in the organization needs access to all SKU information. Within your system, an admin will have the ability to give everyone on your team a level of access that corresponds with their position and job responsibilities. This ensures data security and minimizes the chances of human error or tampering.

Integrate your SKU catalog with other systems.

CPQ (configure, price, quote), ERP (enterprise resource planning), and PIM (product information management) are some systems that can integrate with your SKU catalog (that is, if they don’t have one natively). Integration ensures consistency across all departments, from sales and marketing to procurement and fulfillment.

Train your team on proper SKU management procedures.

Make sure everyone involved in inventory management understands the importance of SKU catalog accuracy and follows the established standards and procedures.

Having a well-trained team ensures consistency and reduces the chances of errors or confusion when managing products.

How SKU Catalogs are Used in CPQ

Within CPQ software, SKU catalogs help sales representatives quickly and accurately configure products and generate quotes for customers. With all the necessary product information already in the system, reps can easily pick the options that match a customer’s needs and preferences. Then, they’ll get an accurate price calculation right away, based on pricing rules.

The catalog facilitates dynamic product configuration. Instead of creating multiple SKUs for every possible product variation, CPQ systems allow for a single SKU with various options and configurations. Dynamic configuration eliminates complexity from managing numerous SKUs and ensures that sales teams can quickly generate quotes for customized product configurations.

One crucial way SKU catalogs can help maximize the ROI of CPQ is through their ability to eliminate unnecessary SKU proliferation. By using a single SKU with configurable options, CPQ software helps businesses avoid the need for creating separate SKUs for each product variation.

Thanks to SKU catalogs, CPQ software also supports product bundling. Sales teams can easily bundle products together to offer comprehensive solutions to customers. This functionality not only enhances sales opportunities but also simplifies the quoting process by allowing pre-configured bundles to be quickly added to quotes.
