- Excess inventory
- Sell-through
- Stranded inventory
- In-stock inventory
This is the number of units that you currently holding within Amazon’s warehouses. Amazon wants to you hold just the right amount of stock in its warehouses to meet the demand. Hold too much and the inventory size is considered excessive and Amazon will recommend you reduce the price to ‘Sell Through’ the stock. On the other side, when you don’t hold enough stock then you will have a low score on the ‘In Stock Inventory’ as you keep running out of stock.

In stock InventoryIt's wise to close all the listings from your inventory at least weekly. Don't worry if you might buy it again, as you can always add it back into your inventory. Clearing down, you're out of stock and inactive products, should happen at least weekly, not only to improve your IPI score but also to help protect your account from intellectual property complaints. We have seen it time and time again, a brand that we have been selling for years, all of a sudden worries about fakes on Amazon. They contact Amazon and ask them to issue an intellectual property complaint to any seller who has any of their ASIN’s on their account. You can only remove these with current wholesale or manufacturer invoice. This is why we recommend you clear them down every week, to protect your account.
