To create a Commercial Invoice in Ship, nShift Customer Service must first activate the document and the Details fields. Once this is done, you must fill in the Details fields in addition to the normal shipment information. 

1. Fill in the relevant fields under the Customs Article tab in the Details section. Add an extra line if needed by clicking the plus icon to the right of the line. The value in GoodsLineNo will connect the details line to a goods line. 
   
   
   
   
2. Next, fill in the relevant fields under the Customs Information tab. Information in these fields applies to the entire shipment.
   
   
3. The Commercial invoice will be generated together with the label.
