Foreign trade may be transacted in one of three ways:
Open Account – This is the case where there is complete trust between exporter and importer. This is the case where the exporter sends the goods and purchase documents directly to the importer's address, and the importer pays the exporter on a pre-agreed future date. Upon the agreed date, payment is made to the exporter as per the invoice. This is the cheapest, most efficient way for both parties to conduct foreign trade.
