Shopify Amazon Inventory Sync Basics
Quick Answer
Before syncing Shopify with Amazon, align SKUs, product identifiers, inventory rules, prices and fulfillment settings. Shopify Marketplace Connect can manage listings, orders, fulfillment and inventory across marketplaces, but sync problems often start with inconsistent product data.
Quick Reference
- Match SKU structure before connecting channels
- Confirm product identifiers and marketplace requirements
- Decide which system controls inventory quantity
- Review price, currency and fulfillment settings
- Test with a small product set before syncing many SKUs

Important Notes
- Marketplace Connect supports connections to sales channels such as Amazon, eBay and Walmart.
- Price and currency behavior can vary by marketplace and region.
- Existing marketplace listings may need careful mapping.
- A bad sync can duplicate listings or create incorrect stock levels.
Best Practices
- Create a SKU map before connecting products.
- Start with a small test collection.
- Check whether inventory is managed in Shopify, Amazon or another tool.
- Keep product titles, images and identifiers consistent.
- Monitor first orders after connection.
Common Mistakes
- Connecting products before cleaning SKUs.
- Using different SKUs for the same physical item.
- Syncing all products at once.
- Forgetting fulfillment and stock ownership rules.
Do / Don't Examples
- Do: SKU SHIRT-BLK-M exists the same way in Shopify and Amazon mapping.
- Don't: Shopify SKU black-shirt-medium and Amazon SKU SHRT-M-BLK for the same item with no map.
- Do: test 3-5 SKUs first.
- Don't: sync an entire catalog before checking errors.
