Smart Inventory lets products share the same physical materials instead of treating every Shopify variant as independent stock. Link transfers, blank apparel, packaging, or other components to product variants. The app calculates sellable quantities, synchronizes inventory, processes order edits, cancellations and refunds, and helps prevent shared-material overselling at checkout.

• Link multiple products to shared materials and component stock
• Sync calculated sellable inventory back to Shopify automatically
• Reserve and restore materials for orders, edits, refunds, and cancellations
• Block carts that exceed shared-material availability at checkout
• Review inventory changes and reconcile mismatches from one activity log
