# How can I ensure my product quantities update correctly on Shopify?

To ensure your product quantities update correctly on Shopify, always verify that your feed has the **Quantity** field mapped to the correct **inventory location** in Shopify. If the location is not selected, Shopify will not register the update.

Additionally, if quantities appear incorrect or updates only work when running the feed manually, check the following:

• Confirm the correct inventory file is being processed by reviewing the **Archive** folder in your SFTP or email feed source.
• Ensure your automation **schedule is running on time**, as delayed or skipped runs can cause outdated quantities.
• Re-run the feed manually after correcting mappings to verify the fix.

These steps help ensure your store receives consistent and accurate quantity updates.
