The Inventory Performance dashboard is the hub for optimizing your FBA business. From this page you can identify opportunities to grow your sales, reduce costs, track key performance metrics, and compare your performance to other sellers.
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 maximise 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 on 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. Performance in this category is measured by the percentage of your FBA inventory units that are currently not available for purchase on Amazon, or Stranded inventory percentage.
In addition to the performance bar, two related metrics of interest are displayed with the Stranded Inventory percentage on the Inventory Performance page:
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 fulfilment centres 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 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 at Restock Inventory by clicking View details 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 page:
