Healthy inventory management starts here

Get your inventory in shape

Measure how healthy your inventory management is with the Inventory Performance Index (IPI) on your Inventory Performance Dashboard (sign-in required). Then use Amazon’s seller guidance to replenish popular products, improve sales, and ensure listings are active. IPI responds over time to how well you balance your inventory levels and sales regularly.

Increase sales velocity

Keep your top-selling products in stock, anticipate demand spikes, and reduce unproductive inventory.

Minimize your costs

Make inventory decisions based on insights to avoid long-term storage fees (LTSF) and holding costs.

Improve your performance

Review and act on suggestions to raise product visibility and lift sales.

Take charge of your inventory

With your active input, these powerful tools can guide your inventory management.

Manage Excess Inventory

Optimize your on-hand inventory levels by knowing when to mark down or remove your products.

Inventory Age

Measuring your performance

Your Inventory Performance Index combines three months of historical sales, inventory, and costs into a single metric. An IPI above 450 means your inventory is performing well and a score above 550 indicates that your FBA inventory is a top performer.

Why IPI scores matter

When you maintain a score at or above 350, you get unlimited storage. A score below 350 could lead to storage limits, limits to your ability to send more inventory, and additional fees. See details ›

Sellers at or above 350

Unlimited storage

No inventory storage overage fees

Sellers below 350

Limited storage

If over storage limit, unable to send more inventory

Subject to inventory storage overage fees ($10 per cubic foot over storage limit)

Improving your score

The best way to increase your IPI score and minimize your FBA storage fees is to reduce unproductive inventory and keep your productive inventory at lean levels while ensuring you have enough on hand to minimize lost sales. Influencing factors* are designed to advise you of opportunities to improve your IPI score.

Using your Inventory Performance Dashboard

How storage limits work

New storage limits take effect October 1, 2018. For FBA sellers with professional plans, these limits are adjusted quarterly. Overage fees may apply. See full policy ›

IPI quarterly review schedule

Amazon will adjust storage limits on a quarterly cycle. If your score is less than 350 six weeks before the end of a quarter, you will be notified of your potential storage limits. If your IPI is still below 350 at the end of that quarter, limits apply for the following quarter. If you are at or above 350 on either date, you will have unlimited storage for the quarter.

Storage limits and fees

You will not be able to create a new shipment to Amazon unless your inventory level is below your storage limit. If your existing inventory exceeds your storage limits, you will also be charged an inventory storage overage fee. 

Frequently asked questions

IPI AND STORAGE LIMITS

We are adjusting our FBA storage fees and policies to encourage improved inventory management, which will help your products be received and delivered to customers more quickly.

Your score is based on how well you maintain healthy inventory levels, fix listing problems, and drive sales. We calculate your Inventory Performance Index for you.

In order for the new storage limit adjustment cycle to apply, you must have an Inventory Performance Index both six weeks before the end of the current quarter and on the last day of the current quarter. If you do not have an index score on either of these dates, you will receive the default storage limits. We will provide additional details on these default storage limits before they take effect on July 1, 2018. For more information, see FBA storage limits changes.

TAKING ACTION AND YOUR SCORE

The "top influencing factors" and recommendations provided on your Inventory Performance Dashboard are intended to help you identify ways to improve your inventory efficiency, but these may not align with your IPI score for a few reasons. First, the Inventory Performance Index is updated weekly based on your inventory’s performance over the last three months, meaning it relies on continual inventory management over several weeks to see improvements. The top influencing factors’ metrics represent a snapshot of your performance today and are not representative of your performance over time. Second, actions taken today will take time to have an impact on performance. For example, creating a sale will only become effective once the product begins selling at a higher rate. For this reason, it may take several weeks before actions have an impact that is reflected in the IPI score.

The absence of recommendations only indicates that, based on your various tool settings and the characteristics of your inventory, there are no actions we believe you should take today. The Inventory Performance Index is updated weekly based on historical performance, meaning it relies on continual inventory management, and your score may be lower due to past performance. We suggest that you monitor your performance and check back for recommendations frequently to ensure you are maximizing the value of your inventory. Also, the recommendations are intended to provide you with information to help you manage your inventory levels, but use of these tools should not be a substitute for your own judgment about demand for your products.

Following the recommendations provided may not immediately improve your score. One reason for this is because your score is based on historical performance and updated weekly. Actions taken today will take time to reflect in the score. Also, the recommendations are intended to provide you with information to help you manage your inventory levels, but use of these tools should not be a substitute for your own judgment about demand for your products.

PRODUCT SPECIFICS

Non-replenishable products are not considered in your Inventory Performance Index once the inventory for those products is depleted (no sales and no inventory). If you have existing inventory of non-replenishable products, the volume of inventory as well as their sales volume will count towards your score, so you should be actively managing your available inventory to improve your score and minimize unnecessary storage fees.

No, dangerous goods storage limit adjustments will be handled separately from this new policy. See FBA dangerous goods (hazmat) program more information.
