Troubleshooting SKUs Not Updating

When an SKU is not updating in Stock Sync, it is usually due to missing product identifiers, filters that prevent updates, duplicate SKU conflicts, or mismatched stock locations. Below are the most common reasons and steps to resolve them.

1. Missing or Blank SKU

If a product has no SKU in your store, Stock Sync cannot match it and therefore won’t update it.

• Add the missing SKU directly in your store.
• Re-run the sync to confirm it updates correctly.

2. Duplicate SKUs Causing Conflicts

If the same SKU appears multiple times in your feed or store, Stock Sync only uses the first match unless duplicate handling is enabled.

• Enable Update duplicate products with the same product identifier under:

Matching Column (Step 2) > Product Identifier > Update duplicate products with same product identifier.

• If duplicate SKUs exist in your feed with different quantities, review and clean up the feed to avoid conflicts.
• Update the Location under Quantity > Smart Settings > Location if different sources report different stock.

3. Vendor or Store Filters Blocking Updates

If store filters are applied, only products matching the filter criteria will update.

• Check your store filters in the feed.
• Remove or adjust filters if the SKU’s vendor or product data does not match the filter.

4. Wrong Stock Location Mapped

If the feed quantity is for a different stock location than the one mapped, the SKU may show as not updating.

• Go to Matching Column (Step 2) > Quantity > Smart Settings > Location.
• Select the correct location corresponding to your feed.

5. SKU Included in Feed but Marked as Unmatched

A SKU may appear in the Unmatch log even if it exists in the feed.

• Verify that the SKU in the feed matches exactly (no spaces, typos, or formatting issues).
• Ensure duplicate SKU settings are enabled when necessary.

6. Feed File Not Parsed Correctly

If row separators or formatting issues prevent Stock Sync from reading the file properly, SKU updates may fail.

• Contact support if the file uses a non‑standard row separator, as this can require backend adjustment.

If you continue to see SKUs not updating after checking the above, review the change logs for additional clues or contact support with sample SKUs for investigation.
