Decide how the app handles inventory for your Amazon-synced products. The Efficient Inventory Control setting offers three options — pick the one that fits your selling strategy.
| Option | What it does |
|---|---|
| Set Fixed Inventory | Sends a fixed stock value to Amazon for every product, regardless of the actual Shopify stock. The product stays available in that quantity. |
| Set Reserved Inventory | Reserves a portion of your stock for other channels or promotions. Only the remainder is sent to Amazon. |
| Set Threshold Inventory | Marks a product as out of stock on Amazon once its Shopify stock falls to or below the threshold value you set. |
