Navigating Amazon IPI Score & Restock Limits: Maximizing FBA Inventory Efficiency

August 24, 2026 · Seller AI

Amazon's Inventory Performance Index (IPI) score plays a crucial role in determining your restock limits. This guide will show you how to manage and optimize your FBA inventory to ensure your business thrives.

As an Amazon seller, maintaining a healthy inventory is essential for your business' success. Amazon's Inventory Performance Index (IPI) score can significantly impact the maximum inventory levels you're allowed to maintain in their fulfillment centers. Let's dive into how to keep your FBA inventory healthy and maximize efficiency.

Understanding Amazon's IPI Score

The IPI score is a 0-1000 scale that measures your inventory management performance. It considers your sales velocity, excess inventory, and in-stock performance. Amazon updates the IPI score monthly, and a higher score means better inventory performance.

Managing FBA Restock Limits

Your IPI score directly influences your restock limits, which are the maximum inventory levels Amazon allows you to maintain in their fulfillment centers. Amazon sets seasonal storage limits based on the IPI score.

• IPI score of 400-499: More restrictive restock limits apply.

• IPI score of 500+: You enjoy more flexibility with no restock limits.

Therefore, improving your IPI score is crucial to avoid stockouts and maintain optimal inventory levels.

Optimizing Inventory Performance

Here are practical steps to optimize your inventory performance:

• Sales Velocity: Ensure your products have a steady demand by running promotions, advertisements, and employing effective pricing strategies.

• Excess Inventory: Regularly review and reduce slow-moving or seasonal items. Utilize Amazon's tools like 'Manage Excess Inventory' to identify and take action on unsold items.

• In-Stock Performance: Keep your best-selling items in stock to maintain a high in-stock performance score. Monitor and adjust your inventory levels based on your sales data.

Adjusting to Changing Market Conditions

Market conditions can affect your sales velocity and IPI score. Be proactive in adjusting your inventory levels and strategies to adapt to seasonal fluctuations or changes in consumer demand.
