This app enables Shopify users who sign up for 'Scan And Ship' (https://www.scanandship.com) to use the 'Scan And Ship' app through their mobile devices. This means that Shopify merchants, who subscribe to Scan And Ship, can accurately pick warehouse items from their in-coming customer orders, using the barcode scanner on their phone - using either a built in scanner or using the mobile devices camera. The app will show the current picking status of each order and allow the picker to complete the orders by picking the items they are guided to by the app. This means that merchants can be sure they are accurately picking the correct items for each order and will greatly reduce the amount of incorrectly picked orders and returns.
