We recommend using the most appropriate term "incoterms" correctly in order to unequivocally establish the individual responsibilities regarding shipping.
In particular, it is good to specify
Goods insurance (it is good to highlight if the goods indicated on the invoice have already been insured, or that it needs to be provided)
Contract, order, order confirmation.
Company name and address of the purchaser.
Possible delivery address, if the destination is different from the billing address.
Nontaxable VAT for exportation.
Person or company responsible for shipping.
