If you are using version 10.0.15 or later you can turn on the new redesigned recall order feature and ensure the recall order operation is added to your POS screen layout. When you open this new experience, it's listening for barcode scans, so simply scan a barcode and we will validate it against: sales order #, channel reference ID, and transaction ID fields to find a match. The order that matches will appear on screen and the details panel at the side will show you all the products on the order. From there you can jump into order fulfillment, editing, pickup or returns functions as needed. Sounds like from here you would click "pick up' which would take you to the transaction cart where payment can be collected and pick up completed.
