Serial Number Manager

Generate Code128 serial labels and scan-assign them at packing without blocking the fulfillment. Serial Number Manager helps merchants handling serialized goods generate Code128 serial barcodes, assign them via scanner during order packing, and verify returns against order history. You can look up serial numbers or order details to check warranty status and history with an integrated admin order block. The app ensures smooth workflows by providing warnings instead of hard-blocking Shopify fulfillment when serials are missing.
