Take a look at our Pick List app. We support paperless scanning, picking, packing, and fulfillment of orders. We also have a basic product location feature implemented via metafields to optimize picking in large warehouses.
15 day free trial. $5 USD per month.
Our app works with handheld barcode scanners and also supports scanning via the camera on Shopify Mobile/POS on iOS and Android.
Contact us and we'd be happy to add more features to support your specific warehouse management requirements.
