If your process already uses a USB scale at the shipping station, ShipStation’s scale integration is generally suitable for pulling weight into the shipment screen. ShipStation documents support for most HID-compliant USB scales when they are connected directly to the workstation and used through ShipStation Connect.
The bigger issue in manual workflows is usually not whether ShipStation can read the scale. It is what still depends on the operator. Weight may be captured correctly, but the process can still break if the wrong shipment is open, the parcel is weighed too late, or other shipment data is entered separately. That is an operational inference based on ShipStation’s documented setup, which is built around a workstation-based manual flow rather than a fully automated capture process.
So the practical answer is this: if you need ShipStation to read weight from a supported scale, the integration is designed for that. ShipStation also provides troubleshooting guidance for incorrect readings and connection issues. But if your concern is the wider reliability of a manual shipping process, a scale integration alone does not remove the weak points in that workflow.
