Navigating Amazon's IPI Score: Strategies for Optimizing Your FBA Inventory

July 06, 2026 · Seller AI

Amazon's Inventory Performance Index (IPI) has become a crucial metric for sellers utilizing Fulfillment by Amazon (FBA). Understanding and optimizing your IPI score directly impacts your inventory health and business growth. Let's dive into how you can manage your FBA inventory efficiently within Amazon's restocking limits.

Amazon's IPI score assesses your inventory performance and storage efficiency on a scale from 0 to 1000. It evaluates your sales velocity, excess inventory, long-storage inventory, and in-stock performance. Sellers whose IPI score is below 400 in a quarter face restocking limits, which can hinder growth and sales. Here's how you can keep your FBA inventory healthy and optimize your IPI score:

Improve Your Sales Velocity

Sales velocity refers to how quickly your inventory sells. To boost this metric, consider offering promotions, discounts, or participating in Amazon's Deal of the Day. These strategies can help increase demand and move products faster, consequently improving your IPI score.

Minimize Excess Inventory

Excess inventory is the amount of unsold products you're storing in Amazon's warehouses. It's vital to analyze your sales data to adjust your inventory levels accordingly. Overstocking can lead to increased storage fees and a lower IPI score. Use Amazon's automated restocking tool or third-party inventory management software to monitor and adjust your stock levels.

Address Long-Storage Inventory

Inventories stored longer than a year incur additional long-term storage fees. To avoid these fees and maintain a healthy IPI, regularly audit your inventory for items that have been in storage for over 365 days. Consider liquidation options such as clearance sales or donations if items are no longer profitable to sell.

Maximize In-Stock Performance

Ensuring that your best-selling items are always in stock is key to a high IPI score. Monitor your inventory levels and lead times closely. Utilize Amazon's forecasted demand to plan your restocking, ensuring you never run out of your top sellers. A high in-stock rate not only boosts your IPI but also improves customer satisfaction and sales.

Plan for Storage Limits

Amazon's restocking limits can be a challenge for growing businesses. To navigate these limits, plan your inventory carefully. Prioritize your best-selling and high-margin products and adjust your orders to meet customer demand without exceeding storage limits. Use Amazon's 'Fulfillment by Amazon (FBA) Storage Space' tool to estimate warehouse space and plan accordingly.
