In short: The Fast-sync feature continuously syncs your Amazon FBA inventory with your Shopify store across multiple global regions. By mapping each Amazon region to a specific Shopify location, your stock levels remain perfectly aligned in real time.
How Fast-Sync Works
Fast-sync ensures that your Shopify stock levels accurately reflect your physical inventory stored across Amazon's global FBA fulfillment centers:
- Real-Time Stock Alignment: As soon as an order is placed or stock levels change on Amazon FBA, Shipr instantly updates the designated Shopify location to match the exact inventory count on Amazon.
- Regional Accuracy: If you sell in multiple countries or market regions, you can map each distinct Amazon region to its corresponding Shopify location so inventory is tracked accurately per market.
Important Requirement for Shopify Locations
To ensure the Fast-sync feature functions properly without sync errors, please take note of how your Shopify locations must be set up:
- Manually Created Locations Only: The Shopify locations assigned in the Shipr app must be created manually by you inside your Shopify Admin (
Settings>Locations). - Do Not Use Third-Party App Locations: Do not select locations that were automatically created or managed by dropshipping apps (e.g., Oberlo), third-party logistics (3PL) services, or custom fulfillment services (e.g., eBay Fulfillment). These external app locations can block Shipr from updating your inventory levels correctly.
