Troubleshooting 424 Inventory Sync

These checks resolve the most common grouping, location, and cart-validation issues.

Items do not appear under Matching SKUs

• Confirm at least two products or variants use the exact same non-empty SKU.
• Remove leading or trailing spaces and check capitalization.
• Confirm Shopify inventory tracking is enabled for the variants.
• Reload Matching SKUs after saving catalog changes.

Inventory does not match

• Confirm the affected items stock inventory at the same Shopify location.
• Open Inventory Sync, choose the trusted highest or lowest quantity, and run Sync now.
• If the app asks for a plan, activate a billing plan before retrying.
• Allow a short processing window after orders or rapid inventory edits.

Cart validation does not block an excessive quantity

1. Confirm SKU Inventory Validation is saved and active under Settings → Checkout.
2. Run Set Metafields once for products that existed before cart validation was enabled.
3. Run a manual inventory sync to refresh the available value.
4. Confirm the cart lines actually share the same SKU.

A location has the wrong quantity

Inventory is synced per location. A quantity at Location A does not become the source for Location B. Ensure every item in the SKU group is stocked at the intended location and reconcile again.
