Connectr can keep quantity in sync between Amazon and Shopify. Choose one of two inventory update options:
Option 1: As available on Amazon
Connectr updates Shopify Inventory quantities to match Amazon stock levels.
Option 2: Fixed count
Connectr sets Shopify quantity to 1 regardless of Amazon stock. When the item sells on Shopify, quantity drops to 0 instead of delisting the product—helping preserve SEO. On the next sync, quantity resets to 1 only if that SKU is in stock on Amazon.
This helps prevent double-selling while keeping listings visible. You can change the Fixed Count Quantity field to a value greater than 1. When you change this setting, existing products update automatically on the next sync.
Example: With Fixed count set to 1, a product that sells out on Shopify shows quantity 0 until Amazon confirms the SKU is back in stock and sync runs again.
