Ups invoice validation is not automatic, for this reason you'll need to follow some simple passages to ship your orders correctly.
Don't worry, we're here to guide you step by step! 🙌
You can actually proceed in two different ways:
When creating the Shipment 📤
Proceed as usual till the Carrier selection step, then click on + Carriers Option > UPS INVOICE NUMBER and Save.
Kindly note that UPS does not support ETD, for this reason you should select "Enable paperless" option in connection module from Carriers > Connection > Edit and ask for E-DOC Service activation to your UPS Sales Person.
This way the commercial invoice will be created, transmitted automatically to the Carrier and you will see EDI appearing on the label.
