Obwohl dies ein alter Faden ist, versuche ich mal, das Chaos ein wenig zusammenzufassen, damit das Nachlesen später nicht so mühsam wird:
Proforma Invoice
A special kind of invoice is the pro-forma-invoice. It is used when the buyer is required
- to pay in advance
- when goods are sent on approval
- or consigned to an agent for sale.
A foreign buyer may send a pro-forma-invoice in order to be able
- to apply for an import licence
- or to instruct his banker to open a documentary credit
A pro-forma-invoice is often sent to a customer
- to show him what the cost of the goods would be if he decided to buy them. In this case the pro-forma-invoice is merely a special form of quotation.
