FBA Inventory Age
The FBA Inventory Age view gives you information regarding the age of your units in FBA. This page shows you the number of units in each age group, the number of units that will be subject to the long-term storage fee (LTSF) on the next charge date, and the estimated LTSF amount for those units (assuming no further sales). The view also shows your recent sales performance for each SKU and identifies opportunities for you to increase traffic or sales conversion to help sell through your aged inventory.
Frequently asked questions
How is inventory age determined?
Inventory age is based on the number of days a unit is in a fulfillment center. FBA accounts for inventory on a first-in-first-out basis across our entire fulfillment network. This means that each sale or removal will be applied to the inventory that has been in our fulfillment network the longest, regardless of which physical unit was actually shipped or removed.
Which products are shown in the Inventory Age view?
Any product that has at least 1 unit available for sale in FBA is shown in the Inventory Age view.
What is the long-term storage fee (LTSF)?
Inventory that has been in a fulfillment center for 365 days or more is subject to a long-term storage fee of $160 per cubic meter or a per-unit minimum charge $0.10, whichever is greater. The LTSF is assessed on the 15th of each month. The Inventory Age page shows your LTSF-eligible units and the estimated LTSF amount as of the next charge date, assuming no further sales. For more information about FBA long-term storage fees, see FBA Long-Term Storage.
How should I use this page to manage aged inventory?
Our goal is to help you easily identify aged inventory that may incur long-term storage fees and provide recommended actions aimed at helping you better manage the investment return on your inventory. In some cases, the recommendation may be to remove units from your inventory, in other instances, we may not recommend any action if your inventory levels are not in excess. Select Improve Recommendation in the drop-down menu to ensure we have accurate information for these SKUs. Several factors influence our recommendations:
- Quality alert – Indicates that the listing may be incomplete or incorrect. Customers search and browse the Amazon catalog using specific product details. If your listing information is incomplete or incorrect, it becomes more difficult for buyers to find, evaluate, and purchase your inventory. Clicking Edit Listing will allow you to edit the listing and fix quality issues.
- Low traffic – Indicates that a low number of potential buyers have seen the listings. Use the Improve Keywords feature in the actions list to optimize how your listing appears in searches.
- Low conversion – Indicates that potential buyers are viewing the listing but do not follow through and purchase the product. Ensuring a high quality detail page through the Edit Listing feature and pricing competitively through Lower Price helps improve conversion rates. In some cases, due to low demand, we may recommend removing some of the inventory if removal is more cost effective than incurring storage fees.
In addition to the alerts, you can also view how many units of a product have been sold over the last 7, 30, 60, and 90 days by hovering over a product’s Units Sold column. If you find that you have an item that you’d like to remove from your inventory, click Create removal order from the action menu.
What if I want to use different inputs to identify potentially excess inventory?
You can set your own unit cost and recovery rate per SKU by selecting Improve Recommendations in the drop-down menu. You can make changes to your default settings by clicking the Inventory Settings link. After making changes, please allow up to 24 hours for the changes to be reflected in your recommendations.
