Managing Amazon IPI Score & Restock Limits for FBA Sellers

June 16, 2026 · Seller AI

As an Amazon seller, maintaining a healthy Inventory Performance Index (IPI) score is crucial for your business' success. Let's explore how to manage your FBA inventory to optimize IPI scores and avoid restock limits.

Amazon's Inventory Performance Index (IPI) is a metric that evaluates your FBA inventory management skills, providing a score that directly impacts your ability to restock products. A score of 350 or above grants you unlimited storage capacity, while anything below triggers inventory limits. Let's dive into strategies to improve your IPI score and manage FBA restock limits effectively.

Understanding IPI Score Components

Amazon calculates your IPI score based on four key performance areas: Excess Inventory Percentage, Inventory Age, Sell-through Performance, and In-stock Inventory Performance. Understanding each component allows you to take targeted actions to improve your score:

• Excess Inventory Percentage: This measures the percentage of your inventory that has been in storage for more than 90 days and hasn't sold for 365 days. To reduce this, consider promotions or discounts to move slow-moving inventory.
• Inventory Age: Focus on maintaining a balance between in-demand products and overstocked items. Amazon considers inventory that's older than 365 days.
• Sell-through Performance: This is a measure of how well your inventory sells relative to the number of units you have in stock. High turnover is favorable.
• In-stock Inventory Performance: Amazon evaluates how often your items are in stock. Aim for a 90% in-stock rate or higher.

Strategies to Improve IPI Score

With a clear understanding of IPI components, you can implement the following strategies:

• Optimize Inventory Levels: Regularly review your inventory and adjust quantities to match demand, reducing the risk of overstocking or understocking.
• Improve Sell-through Rate: Use Amazon Advertising to boost visibility and sales velocity. Consider adjusting prices to encourage purchases.
• Regularly Monitor Your IPI Score: Check your IPI score monthly to identify areas needing improvement and act on them promptly.
• Use FBA Inventory Health Dashboard: This tool allows you to monitor your inventory health and take corrective measures before issues become critical.

Dealing with FBA Restock Limits

If your IPI score drops below 350 due to factors like increased demand or seasonal fluctuations, here's how to manage FBA restock limits:

• Review Your Inventory: Identify which products are contributing to your low IPI score and consider reducing them.
• Utilize LTL Shipments: For bulkier items, consider Less-Than-Truckload (LTL) shipping to optimize storage and reduce costs.
• Manage Storage Efficiently: Use Amazon’s long-term storage service or consider a third-party logistics provider if you exceed storage limits.
