Fulfillment Scanner App

[andreaa_]

I am looking for an app to limit fulfillment discrepancies. Ideally we need  an app that we can scan products into an order to make sure they match the product that was ordered, before it's shipped. Maybe an alert of mismatched product. Hopefully this stops our fullfillment team from packing up the wrong size/style. Please let me know if you know of or use an app like this. Or any other ideas to relieve this issue.
