Payment in international trade is much more complicated than that in domestic trade. The most generally used method of payment in financing international trade is the Letter of Credit (abbreviated to L/C), which is reliable and safe for both sellers and buyers. There are various types of L/C, including irrevocable documentary credit, revolving credit, standby credit and so on. The parties concerning a documentary credit are: the applicant (importer or buyer), the negotiating bank, the advising bank, the confirming bank (if any), the nominated paying bank and the beneficiary (seller or exporter).

货款支付在国际贸易中较之国内贸易中更为复杂。国际贸易最普遍采用的货款支付方式是信用证（缩写为L/C），这种支付方式对买卖双方来说，既安全又可靠。信用证有多种形式，如不可撤销的跟单信用证、循环信用证、备用信用证等。跟单信用证的有关参与方有：开证申请人（进口商或买方）、开证行、通知行、保兑行（如果需要保兑的话）、指定的付款行以及受益人（卖方或出口商）。
