Frequently asked questions

What units are shown in the Inventory age column view?

The Inventory age column includes available plus reserved units minus units that are pending removal . These are shown for any product that has at least one unit available for sale through Fulfilment by Amazon (FBA).

How is inventory age determined?

Inventory age is based on the number of days that a unit has been in the fulfilment centre. FBA accounts for inventory on a first-in, first-out basis across our entire fulfilment network. This means that each sale or removal will be applied to the inventory that has been in our fulfilment network the longest, regardless of which physical unit was actually shipped or removed.

What is the estimated long-term storage fee?

If the long-term storage fee is applicable to the Amazon store in which you sell, inventory that has been in a fulfilment centre for more than 365 days is subject to the fee. The fee is assessed on the 15th of each month. Inventory age shows the number of units that would be subject to the long-term storage fee and the estimated fee amount as of the next charge date, assuming no further sales. For more information, go to FBA Long-term storage fees.

What is included in the total inbound quantity?

For an FBA listing, total inbound quantity refers to fulfillable units that are available or on their way to the fulfilment centre. It does not include unfulfillable units (such as damaged units) or units reserved for a customer order. For a merchant fulfilled listing, the total quantity is the same as the available quantity, as specified by the seller.

How should I use this page to manage my potentially excess and aged inventory?

Our goal is to help you easily identify inventory which is potentially excess or aged, and provide recommended actions aimed at helping you better manage the return on your inventory investment. In some cases, the recommendation may be to remove units from your inventory. Several factors influence our recommendations, which should always be treated as a guide only, particularly as past performance is not a guarantee of future results.

You can also view how many units of a product have been sold over the past 7, 30, 60, and 90 days by hovering over details in the Sales summary column for each product. This will allow you to gauge sales relative to your total inventory. If you want to remove an item from your inventory, select Create removal order in the actions list.

Why does Amazon generate recommendations?
