How it sells itself

When processing a refund, the restock checkbox is checked by default. If merchants forget to uncheck it, out-of-stock products get incorrectly restocked, causing inaccurate inventory levels. Restock Blocker gives merchants control over restock behavior using three rules: a Global Rule to disable restocking store-wide, a Tag Rule for products with specific tags, and a Product Rule for individual products.

Merchants often forget to uncheck the restock box during refunds, which silently returns sold-out or returned items to available inventory. This causes overselling, false back-in-stock alerts, and customer complaints. Stock Warden watches every refund and automatically corrects these unintended restocks, usually within seconds. It works in the background with no manual steps.

Key points
  • Global Rule: Disable restocking for your entire store during refunds.
  • Tag Rule: Block restocking for products matching specific tags.
  • Product Rule: Control restocking for individual products with highest priority.
  • Automatically reverses accidental inventory restocks created during refunds
  • Smart Protection only corrects items that were out of stock before the refund
  • Product, collection, and custom rules with full multi-location support
