What steps should I take if my update feed does not reflect accurate stock levels?

If your product feed is showing incorrect stock levels, please check the following common causes to troubleshoot the issue:

• Mismatched SKUs: Ensure the SKUs in your store exactly match the SKUs in your feed file. Missing or mismatched identifiers are the most common reason syncs fail.
• Incorrect Column Mapping: Verify that your quantity field is mapped to the correct column. Please note that field and column headers are case-sensitive.
• Missing Products in the Feed: Check if the item actually exists in your feed file. If the supplier omitted the product from the file, syncX: Stock Sync cannot update it.
• Store Variant Limit Reached: If your store exceeds the variant limit for your plan, Stock Sync will stop updating products. Increase your variant limit or reduce total variants, then rerun the feed.
• "0 Match" or Bulk Zero Updates: If your inventory is suddenly dropping to zero, verify your Out of Stock Strategy settings. Some suppliers only include in-stock items in their file. If an item is missing, your OOS rule determines if it gets set to zero.
• File Parsing Issues: In some cases, adjusting the file encoding or switching to column index mapping instead of column names can resolve layout issues.
