What Is SKU Rationalization?
SKU rationalization is the process of evaluating your product catalogue to identify which items to keep, discontinue, or consolidate. Learn how it improves profitability.
Key Takeaways
- SKU rationalization analyses each product's contribution to revenue, profit, and strategic goals to determine whether it should stay in the catalogue.
- Most businesses find that 20-30% of their SKUs generate 70-80% of profit, following the Pareto principle.
- Removing underperforming SKUs reduces inventory costs, simplifies operations, and often increases overall profitability.
What SKU rationalization involves
SKU rationalization is a systematic review of every product in your catalogue to determine its value to the business. Each SKU is evaluated against criteria including sales volume, profit margin, inventory carrying cost, return rate, and strategic importance. Products that fail to justify their place are candidates for discontinuation, consolidation with similar items, or pricing changes. The goal is a leaner, more profitable product assortment.
Why it matters
Every SKU in your catalogue carries costs: storage space, management time, potential obsolescence, and complexity in purchasing and fulfilment. A product that sells five units per month at a 10% margin may cost more to maintain than it earns. For ecommerce sellers on platforms like Jumia or Takealot, each listing also requires ongoing content management, customer service resources, and advertising spend. Removing unprofitable SKUs frees resources for products that actually drive the business.
How to run the analysis
Start by ranking all SKUs by gross profit contribution over the past 12 months. Identify the top 20% that generate the majority of profit. Then examine the bottom 20% — calculate the total cost to maintain each, including storage, listing fees, and management time. Flag products with declining sales trends, high return rates, or negative margins. Cross-reference against strategic factors: does the product attract new customers or complement a high-margin item?
Making the decision
Not every low-volume product should be cut. Some items serve as entry points that lead customers to higher-margin purchases. Others fill a category gap that competitors would exploit. The rationalization decision should weigh financial data against strategic context. When removing a SKU, plan the exit: run clearance pricing to liquidate remaining stock, update marketing materials, and redirect traffic to alternative products. Review your catalogue quarterly to prevent SKU creep.
