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.
Incorrect Inventory Location: If your store uses multiple locations, make sure the correct Inventory Location is selected in the feed’s Quantity > Smart Settings. An incorrect location will cause updates to appear as if nothing changed.
Duplicate SKUs Updating Unexpectedly: If multiple variants share the same SKU, Stock Sync will update all of them with the same quantity. Ensure your feed includes variant‑level quantities if you require different stock per variant.
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.
"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.
Non-Unique Variant Identifiers: If variants share the same SKU or identifier, only one variant will update and others may duplicate quantities. Ensure every variant has a unique identifier by combining fields (e.g., SKU + Option1 + Option2) or adding a new unique column in the feed.
Thousand Separator Formatting Issues: If your feed uses dots or commas as thousand separators (e.g., 1.700 or 1,700), update the quantity field delimiter settings so the value parses correctly.
Attribute Mismatches (e.g., color/size names): If variant attributes in your feed use codes (e.g., GRNT) and your store uses full names (e.g., Granate), they will not match. Convert or map the feed values so they match the store exactly.
