The Inventory Performance dashboard helps you identify opportunities to grow your sales, reduce costs, and track key performance metrics.
The Inventory Performance Index, or IPI, is a metric to gauge your inventory performance over time.
IPI score measures how efficient and productive you are in managing your FBA inventory. Multiple factors could influence your IPI score, however, the most important ones are your actions: 1) maintain a balanced inventory level between sold and on-hand inventory and avoid excess inventory (overstock), 2) avoid long term storage fees, 3) fix listing problems, and 4) keep your most popular products in stock at the right levels, when possible, to meet customer demand and maximize customer satisfaction.
For answers to common questions, refer to IPI frequently asked questions.
There are four categories of recommendations to help improve your IPI:
The IPI dashboard displays a performance bar for each of the four categories:
The Inventory Performance page also provides additional metrics of interest within each factor, which you can see by selecting Show more details. Clicking the Show more details box associated with each category will take you to related inventory management tools, which provide recommendations to improve your performance.
We consider an item excess (overstock) if it has over 90 days of supply based on the forecasted demand.
Track your Excess inventory percentage, which is the percentage of your FBA inventory units that have been identified as excess.
In addition to the performance bar, three related metrics of interest are displayed with the Excess inventory percentage on the Inventory Performance dashboard:
When inventory is not available for purchase due to a listing problem, it results in lost sales and storage costs. This inventory is referred to as stranded inventory. Your Stranded inventory percentage is measured by the percentage of your FBA inventory units that are currently not available for purchase on Amazon.
In addition to the performance bar, two related metrics of interest are displayed with the Stranded inventory percentage on the Inventory Performance dashboard:
Maintain the right balance of inventory with your rolling 90-day FBA sell-through rate, which is your units sold and shipped over the past 90 days divided by the average number of units on-hand in our fulfillment centers during that time period.
In addition to the performance bar, two related metrics are also displayed with your FBA sell-through rate on the Inventory Performance dashboard:
Keeping popular, replenishable products in stock helps maximize your sales. You can track your performance in this category using the FBA in-stock rate, which is the percent of time your replenishable FBA ASINs have been in stock during the last 30 days, weighted by the number of units sold for each SKU in the last 60 days.
You can indicate that a SKU is non-replenishable in Restock inventory by going to the drop-down menu in the Action column and selecting Hide recommendation. Hiding all SKUs associated with an ASIN will exclude the ASIN from your FBA in-stock rate and estimated FBA lost sales.
In addition to the performance bar, two related metrics of interest are displayed under the replenishable FBA in-stock rate percentage on the Inventory Performance dashboard:
