How to resolve SKU matching failures in Stock Sync

SKU matching can fail when Stock Sync cannot find an identical identifier between your feed and Shopify. Common causes include:

• Active filters preventing the item from being included (for example, “Only include variants where Available Quantity > 0”). If a product has 0 quantity in Shopify, Stock Sync may skip it even if the feed shows a positive quantity.

• Formatting differences such as prefixes, postfixes, or number formatting changes introduced by spreadsheet software.

• Using SKU as the Unique Product Identifier prevents the app from overwriting the SKU. If SKUs need correction, temporarily switch the identifier to another unique field such as barcode or title, map the correct SKU column, run the update, then switch back.

Removing restrictive filters and ensuring exact identifier matches usually resolves most SKU matching issues.
