Amazon’s Inventory Performance Index (IPI) is a critical metric that directly impacts your ability to store products in Amazon’s fulfillment centers. A high IPI score allows you to maximize your inventory storage, while a low score can lead to storage limitations and additional fees. In this article, we’ll explore what the IPI is, how it’s calculated, and the strategies you can use to maintain a high score, ultimately boosting your sales performance on Amazon.
What is Amazon’s Inventory Performance Index (IPI)?
The Inventory Performance Index (IPI) is a metric used by Amazon to measure how efficiently and effectively sellers manage their inventory in Amazon’s fulfillment centers. It is designed to ensure that sellers maintain the right balance of inventory—neither overstocked nor understocked.
A high IPI score (typically above 400) indicates efficient inventory management, leading to unlimited storage capacity. Conversely, a low IPI score can result in storage restrictions, which may hinder your ability to meet customer demand.
How is the IPI Score Calculated?
Amazon calculates the IPI score based on four key factors:
- Excess Inventory
- Measures the percentage of inventory that is overstocked. Maintaining low excess inventory helps reduce storage fees and improves cash flow.
- Sell-Through Rate
- This is the rate at which your inventory is sold and replenished. A high sell-through rate indicates healthy product demand and efficient inventory turnover.
- Stranded Inventory
- Stranded inventory occurs when products are in fulfillment centers but are not actively listed for sale. Resolving stranded inventory issues promptly helps maintain a high IPI score.
- In-Stock Rate
- This measures how often your popular products are in stock. Maintaining a high in-stock rate ensures you meet customer demand without losing potential sales.
Why is IPI Important for Amazon Sellers?
Your IPI score directly impacts your storage limits and fees. Here’s how:
- Storage Limitations: If your IPI score falls below Amazon’s threshold (usually 400), you may face storage restrictions, limiting the number of units you can store in Amazon’s fulfillment centers.
- Additional Fees: Low IPI scores can lead to increased storage fees, particularly for overstocked and slow-moving inventory.
- Sales Impact: Inadequate inventory storage can result in stockouts, leading to lost sales opportunities and a negative impact on your Amazon ranking.
Maintaining a high IPI score not only optimizes your storage but also ensures consistent product availability, enhancing customer satisfaction and boosting sales.
Tips to Improve and Maintain a High IPI Score
- Regular Inventory Audits
- Conduct regular audits to identify overstocked, slow-moving, or stranded inventory. Take corrective actions such as discounts, promotions, or removal orders to clear excess stock.
- Optimize Sell-Through Rate
- Use Amazon’s advertising tools to promote slow-moving products. Running strategic promotions or sponsored ads can increase visibility and boost sell-through rates.
- Monitor and Resolve Stranded Inventory
- Regularly check for stranded inventory and resolve listing issues to make the products available for purchase again.
- Maintain Healthy In-Stock Rates
- Keep a close eye on inventory levels for high-demand products. Use Amazon’s Restock Inventory tool to maintain optimal stock levels.
- Seasonal Inventory Planning
- Anticipate demand spikes during peak seasons (e.g., holidays, back-to-school) and plan your inventory accordingly to avoid stockouts or overstocking.
- Leverage Data Analytics
- Utilize inventory management software or Amazon’s inventory reports to gain insights into sales trends, enabling data-driven decisions for inventory replenishment.
