Share of B-category Items (SBI)

Understanding product performance and its distribution can have a significant impact on inventory management, marketing strategies, and purchasing decisions. One such critical metric is the Share of B-Category Items.

This metric measures the share of products that contribute a significant, but not dominant, portion of a company’s revenue. By examining the Share of B-Category Items, companies can determine assortment balance and identify opportunities for assortment optimization.

Key Takeaways

  • Definition: Share of B-Category Items measures the proportion of products that contribute a significant, but not dominant, portion of a company’s revenue.
  • Calculation: To calculate the Share of B-Category Items, divide the number of B-category items by the total number of items (SKUs) and multiply by 100.
  • Strategic Importance: The Share of B-Category Items is important for assortment optimization, inventory management, marketing opportunities, supplier negotiations, and consumer demand analysis.
  • Optimization Strategies: Strategies to optimize the share of B-category items include promotional activities, inventory replenishment, product bundling, customer feedback analysis, and price optimization.
  • Limitations: Share of B-Category Items may not reflect sales impact, can be misleading, doesn’t indicate purchase frequency, requires periodic reevaluation, is subject to seasonal fluctuations, and doesn’t differentiate between profit margins.
  • Complementary metrics: It is important to consider other metrics such as share of A category items, share of C category items, inventory turnover ratio, gross margin return on inventory investment (GMROII), and SKU proliferation to gain a comprehensive view of e-commerce performance.

Why does Share of B-category Items matter for your business?

  1. Assortment Optimization: If a large number of products fall into the B-category, it indicates that your product range is diverse, with several items contributing fairly to revenue. This balance reduces dependency on a few top-performing products.
  2. Inventory Management: By identifying B-category items, businesses can manage inventory levels more efficiently, ensuring that these products are always available, given their steady contribution to revenues.
  3. Marketing Opportunities: B-category items often have potential to move up the ladder. By strategically marketing these products, businesses can convert them into A-category items, increasing their revenue contribution.
  4. Supplier Negotiation: A clear understanding of B-category items allows businesses to negotiate better terms with suppliers since these products consistently bring in revenue.
  5. Consumer Demand Analysis: Tracking the share of B-category items offers insights into consumer preferences and can guide product development or procurement strategies.

How to calculate Share of B-category Items (SBI)?

\[ \text{Share of B-category Items (\%)} = \frac{\text{Number of B-category Items}}{\text{Total Items (SKU)}} \times 100 \]

Explanation of the parts of the formula:

  • Number of B-category Items represents the specific count of items that fall under the B-category. These items typically generate an intermediate amount of revenue for a business, based on the Pareto Principle (80/20 rule).
  • Total Items (SKU) refers to the entire assortment or count of different stock-keeping units available in the product range. This includes all items regardless of their category or popularity.
  • The ratio tells us the proportion of items that are classified as B-category out of the entire product assortment. The resulting decimal value lies between 0 and 1 (or can be expressed as 0% to 100% when multiplied by 100).
  • Multiplying the above-calculated ratio by 100 provides the percentage representation of B-category items out of the total assortment.

Essentially, the Share of B-category Items (%) provides an insight into the distribution and balance of a business’s product assortment. If the percentage is very high, it might indicate an over-reliance on intermediate performing products. Conversely, a very low percentage might suggest that the business is overly reliant on its top or low performing products.

Example Scenario

Suppose for a retail store:

  • The store offers a total of 5,000 different products (or SKUs).
  • Of these 5,000 products, 2,500 are classified as B-category items.

Plugging these numbers into the given formula:

  • Share of B-category Items (%) = (2,500 / 5,000) × 100
  • Share of B-category Items (%) = 0.5 × 100
  • Share of B-category Items (%) = 50%.

This indicates that half of the products offered by the retail store are B-category items.

Tips and recommendations for optimizing Share of B-category Items

Promotional activities

Engage in strategic marketing campaigns to raise the profile of B category products, making them more visible and appealing to consumers. This may include targeted advertising through various channels such as social media, email marketing, and online marketplaces. Work with influencers or industry experts to endorse and showcase the benefits of B category products. In addition, consider offering limited-time promotions or discounts to create a sense of urgency and encourage immediate purchase.

Inventory replenishment

Ensure that B category items are always in stock, as they are a consistent contributor to the bottom line. Monitor inventory levels closely and implement efficient replenishment processes to avoid out-of-stocks. Use inventory management systems to accurately track sales and forecast demand for B category items. Consider implementing automated reordering systems or low-stock alerts to ensure timely replenishment and uninterrupted availability to customers.

Product bundling

Bundle B-category items with A- or C-category products to enhance their appeal and increase sales. Identify complementary products that can be packaged together to create value for customers. Highlight the cost savings or added benefits of purchasing the bundled products. Promote these bundles through your marketing channels and ensure they are prominently displayed on your Web site or in-store to maximize visibility and encourage customers to purchase.

Customer feedback

Actively solicit and analyze feedback on B category products to identify areas for improvement and improve performance. Encourage customers to leave reviews and ratings on your website or third-party platforms. Regularly monitor and respond to customer feedback, addressing any concerns or issues in a timely manner. Use this feedback to identify patterns or common complaints and make necessary improvements to B category items. Consider implementing a customer feedback system or conducting surveys to gain more targeted insights.

Price optimization

Regularly review and adjust B category item prices based on market trends, competitors, and demand to increase their sales potential. Monitor competitors’ prices and make sure your B category items are competitively priced. Consider offering occasional discounts or promotions to encourage customers to purchase these items. Analyze sales data and customer buying patterns to identify optimal price points for different B category products. Experiment with pricing strategies such as dynamic pricing or price bundling to find the most effective approach for maximizing sales and profitability.

Examples of use

Inventory Forecasting with AI

  • Scenario: An online apparel retailer observes inconsistent stock levels, leading to frequent stockouts of popular items and overstock of slow-moving items.
  • Use Case Application: By leveraging AI-driven inventory forecasting tools, the retailer can predict demand patterns for various items based on historical sales data, trends, and seasonality. Using these insights, the retailer can optimize stock levels, ensuring popular items are always available and reducing holding costs for slow-moving stock. This approach not only enhances customer satisfaction by avoiding stockouts but also improves inventory turnover rates.

Dynamic Pricing Strategies

  • Scenario: A digital bookstore notices that sales of certain ebooks fluctuate with current events or pop culture trends.
  • Use Case Application: By implementing a dynamic pricing strategy, the digital bookstore can adjust ebook prices in real-time based on demand, competitors’ pricing, and current events. This means they can increase prices for trending ebooks and offer discounts for less popular ones, ensuring maximum profitability and attracting a wider audience.

Virtual Try-Ons for Eyewear

  • Scenario: An online eyewear shop realizes that although traffic to their site is high, conversion rates are low because customers are hesitant to purchase without trying glasses on.
  • Use Case Application: By integrating augmented reality (AR) technology into their platform, the online shop offers a virtual try-on feature. Customers can virtually “wear” different eyeglass frames using their device’s camera, allowing them to visualize how they look before purchasing. This not only enhances the user experience but also boosts confidence in the purchase, leading to higher conversion rates.

Chatbots for Customer Support

  • Scenario: A tech gadget ecommerce store receives frequent inquiries about product specifications, shipping, and returns, leading to long waiting times and frustrated customers.
  • Use Case Application: Implementing a chatbot on the ecommerce platform can instantly address common queries, guide customers through product selection, and provide information on shipping and returns. This real-time assistance enhances user experience, reduces the burden on human customer service representatives, and can also upsell or cross-sell products during the interaction.

Flash Sale and Limited-Time Offers

  • Scenario: An online electronics retailer sees a consistent number of visitors but lacks the necessary engagement to convert these visits into sales.
  • Use Case Application: Introducing flash sales or limited-time offers can create a sense of urgency among customers. By offering significant discounts on specific products for a short period, customers are more likely to make impulsive decisions and complete the purchase. This tactic not only clears out older inventory but also attracts more traffic and engagement, potentially leading to higher sales volumes and greater revenue.

Limitations of using Share of B-category Items

While the Share of B-category Items is an essential metric for assessing the diversity of a product assortment in an ecommerce setting, it comes with certain limitations when applied in business analysis:

  • Doesn’t Reflect Revenue Impact: The share of B-category items gives an understanding of product assortment, but it doesn’t necessarily correlate with revenue. A higher share doesn’t always mean increased sales or profitability.
  • Can Be Misleading: An increase in the share of B-category items might give an impression of balanced inventory, but if these items don’t resonate with the target audience, it could lead to increased holding costs and dead stock.
  • Doesn’t Indicate Purchase Frequency: A larger share of B-category items doesn’t provide insights into how frequently these items are purchased, which is essential for inventory management and demand forecasting.
  • Requires Regular Re-evaluation: What’s classified as B-category today might shift to A or C category in the future based on sales data and customer preferences, requiring constant re-analysis.
  • Subject to Seasonal Variations: The share of B-category items can be influenced by seasonal trends, like holiday promotions or end-of-season sales, leading to skewed data.
  • Not Necessarily Aligned with Brand Positioning: Overemphasis on increasing the share of B-category items might make the brand deviate from its core products or values.
  • Overemphasis Can Impact Marketing Efforts: If too much focus is placed on promoting B-category items, it might divert attention from A-category items which might be significant revenue drivers.
  • Doesn’t Differentiate Between Profit Margins: All B-category items might not have the same profit margins. Thus, having a higher share doesn’t guarantee higher profitability.

In summary, while the percentage of B-category items is useful for understanding product diversity, it should be used in conjunction with other metrics to gain a holistic view of an ecommerce business’s performance. Relying solely on this metric can lead to biased strategic decisions.

KPIs and metrics relevant to Share of B-category Items

  • Share of A-category Items: These are the top-performing products, generally responsible for 80% of revenue. A low share of B-category items combined with a high share of A-category items could indicate an overly concentrated revenue stream, making the business vulnerable to changes in demand for a few products.
  • Share of C-category Items: These products typically bring the least revenue. If the share of B-category items is decreasing while C-category items are increasing, it may indicate that more products are underperforming and not meeting revenue expectations.
  • Inventory Turnover Ratio: This measures how many times a business’s inventory is sold and replaced over a period. If B-category items have a high inventory turnover ratio, it might indicate that these products are popular and are being replenished frequently, making them critical for consistent revenue.
  • Gross Margin Return on Inventory Investment (GMROII): This metric evaluates the profit return on the money invested in stock. A high GMROII for B-category items would mean these items are not only generating revenue but are also profitable.
  • Stock Keeping Unit (SKU) Proliferation: This refers to the number of distinct items or SKUs a business carries. If the number of B-category SKUs is high and increasing, it might be time to reconsider the product range and possibly phase out underperforming SKUs.

By understanding and optimizing the share of B-category items in conjunction with these metrics, companies can balance product assortments, optimize inventory, and make more informed decisions to improve profitability and operational efficiency.

Final thoughts

The share of B-category items is a key metric in e-commerce that helps optimize product assortment, manage inventory, and increase revenue. By actively monitoring and optimizing this metric, companies can balance their product assortment, maximize revenue from all product categories, and reduce dependency on a few top performers.
