How to sync inventory with duplicate SKUs?

Yes, you can sync by enabling this option, which updates duplicate SKUs with the same product identifier.

By default, if multiple products share the same SKU or identifier, only the first matching product will be updated. Enabling the duplicate‑update option ensures all matching products are updated.

If your store contains duplicate SKUs across different products, this may also cause issues such as skipped updates or missing data during feed processing. In such cases, review and merge duplicate product entries or assign unique SKUs to prevent conflicts.

Note: This applies only to updates coming from a feed (file, Google Sheet, supplier, or another Shopify store). Stock Sync cannot sync inventory between duplicate products inside the same store based on orders or manual stock changes in Shopify.

You can find these options from Matching Column (Step 2) > Product Identifier field > Update duplicate products with the same product identifier.
