We greatly appreciate your post to our feature request forum. Your active feedback helps us to consider what future features to look into.
Your detailed explanation is very helpful! We have logged your request and it will be under consideration for prioritization.
In the meantime, you might consider checking out one of our integration partners, Groovepacker. They currently offer barcode inventory control and scan pack QC system while also being able to connect to ShippingEasy.
If there are any updates regarding direct options for this via ShippingEasy, we will be sure to update this post and direct other customers to share their feedback here as well!
