What should I do if my product information was overwritten in Shopify?

Stock Sync can only undo added products using the Undo button. If an update feed overwrote existing product information (such as titles, descriptions, prices, or images), the data cannot be restored automatically unless you previously created a backup such as a Shopify CSV export.

When product details are overwritten, the only options are:
• Restore products from your own backup (CSV export or external backup app).
• Manually correct the affected product information in Shopify.
• If supplier data caused the overwrite due to mismatched SKUs, ensure your store SKU matches the supplier SKU before running any new import. Stock Sync matches products by SKU and copies the mapped field values; it is not aware when the supplier and store SKUs refer to different products.
• For duplicate SKUs belonging to different brands or vendors, configure the product identifier using a combination such as SKU and Brand/Vendor to prevent updates from affecting the wrong product.

Stock Sync does not keep a historical version of your product data and cannot revert updates that modified existing products. Before a large or first import, create a backup and test the feed with a small set of products. If you discover an overwrite, review the import/change log to identify the affected products and mapped fields, then stop or disable the feed before running another sync. Restore the data from your backup or correct it manually. If a large import is still running, do not cancel it; wait for it to complete, then use an update feed to correct any inconsistencies.
