If products are showing a Sold Out badge unexpectedly, the issue is usually in Shopify inventory settings rather than the theme itself.

Quick checks (2–3 minutes)

Open the product in Shopify Admin and check variant stock quantity.
Confirm Track quantity is configured the way you expect.
If you allow backorders, enable Continue selling when out of stock.
Make sure the product is available on your Online Store sales channel.
Recheck the same product on the live storefront (not only in the theme editor).

Why this happens often

From support cases, merchants usually run into this after bulk edits, market/channel changes, or variant-level stock updates. One variant at 0 can still trigger unexpected states if configuration is inconsistent.

Practical prevention tips

Use one stock workflow: avoid mixing manual stock edits and app automations without rules.
Audit top products weekly: check quantity + channel availability together.
Test one product per collection: confirm live behavior before large updates.

If inventory is correct but the badge is still wrong, share your product URL and a screenshot of the variant inventory settings so support can check faster.
