There are five major types of international payment methods used in business: 1) Documentary collections where a buyer's bank collects payment from the buyer after receiving an invoice from the seller. 2) Letters of credit where a bank guarantees payment to the seller upon presentation of shipping documents. 3) Cash against documents where payment is made after goods are shipped based on viewing shipping documents. 4) Open account trade where goods are shipped without immediate payment and the seller waits to receive payment after goods are sold. 5) Consignment where goods are shipped for sale by an agent with payment remitted after sale of the goods.
