Why are my SKUs not updating even though they exist in the feed?

If SKUs in your feed are not updating in Stock Sync, even though they are present in the file, the most common causes are:

• Hidden characters in the header (such as BOM symbols) that prevent correct column recognition. In this case, mapping the SKU column by index number instead of by column name will fix the issue.

• Duplicate SKUs in the store or feed. If multiple products share the same SKU, ensure the setting "Update duplicate products with same product identifier" is enabled.

• SKU formatting differences, such as spaces, capitalization, supplier prefixes, or missing/extra leading zeros. Make sure the SKU in the feed matches the store SKU exactly.

• Incorrect inventory location settings. Ensure the correct location is selected for updates.

If SKUs are still not updating, check the feed activity logs for errors and confirm the SKU is present at the time of processing.
