Navigating Amazon IPI Score and Restock Limits: Strategies for FBA Inventory Health

July 15, 2026 · Seller AI

Managing inventory on Amazon FBA can be a balancing act, especially with the introduction of restock limits and the Inventory Performance Index (IPI) score. Understanding these elements is crucial for keeping your business running smoothly and efficiently.

Amazon's Inventory Performance Index (IPI) is a metric that measures the performance of your inventory. It's based on several factors, including sell-through rates, inventory turnover,过剩库存(Excess Inventory), and仓储年龄(Storage Age). A high IPI score indicates you're effectively managing your inventory, which in turn can impact your ability to meet customer demand and your overall FBA storage limits.

Why is IPI Score Important?

Your IPI score directly influences your storage capacity and thus, your business's scalability. A score of 400 or higher allows for unlimited storage, while scores below that limit your storage capacity. Since this is a rolling 60-day average, your score can change monthly, affecting your restock capacity and inventory planning.

How to Improve Your IPI Score

• Optimize Sell-through Rate: Focus on selling products faster by adjusting pricing, promotions, and advertising strategies.
• Reduce Excess Inventory: Regularly review and clean up stagnant listings to prevent accumulating excess inventory.
• Improve Inventory Turnover: Ensure your inventory is rotating quickly to meet customer demand.
• Manage Storage Age: Keep storage duration low by selling aged inventory or considering disposal if it's not profitable.

Dealing with Restock Limits

When Amazon imposes restock limits, it's crucial to understand your restock capacity and the items you can send to Amazon. Use the 'Manage Excess Inventory' dashboard to identify potential issues and solutions. Prioritize sending items with higher demand and consider reducing less popular items that might contribute to excess inventory.

Inventory Planning

Proactive inventory planning is key. Use Amazon's analytics tools to forecast demand and schedule your shipments accordingly. Regularly monitor your inventory levels and adjust your restocking based on your IPI score, sales velocity, and seasonal trends.
