What causes discrepancies in the stock quantity reported by the feed files?

Discrepancies in stock quantities can occur when Stock Sync detects conditions that differ from what appears in the feed file. Common causes include:

• The feed contains a large number of products with quantity set to 0, triggering the safety warning that halts updates when over 80% of items appear out of stock.
• Cached data from previous runs may cause the system to read outdated quantities. In some cases, disabling caching resolves the issue.
• If an update runs successfully only once but later attempts show all quantities as zero, this usually indicates that the file provided by the source system contains zero quantities at that time.

If the feed file itself does not show these zeros, the source system may be temporarily generating incomplete or empty data. Checking a sample SKU and confirming its expected quantity helps identify whether the issue lies in the feed file or the syncing process.
