Google Merchant Center availability mismatch for Shopify

What to check first

• Check the exact affected Shopify variant, not only the parent product.
• Confirm whether inventory tracking is enabled for that variant.
• Check if "continue selling when out of stock" is enabled.
• Open the product page and select the same variant Google is crawling.
• Compare Merchant Center availability against the feed app's submitted value.

Common Shopify causes

Common causes include variant-level inventory differences, hidden default variants, preorder apps, subscriptions, market-specific availability, sold-out products still published to Google, and stale feed syncs.

Fast diagnosis method

• Export affected Merchant Center items.
• Match each item ID to the Shopify variant ID or handle.
• Compare inventory quantity, inventory policy, published status, and product page status.
• Fix repeated patterns in Shopify or your feed app.
• Wait for the next feed refresh before requesting another review.
