外贸以信用证结算，为什么要求出口人（卖方）开具汇票？
推荐回答（3个）
汇票是一种结算工具，跟结算方式使不使用信用证没有必然的联系。信用证中使用汇票我觉得最主要的原因还是方便融资，贴现。特别是在远期信用证中，如承兑信用证，卖方不能立即得到银行的付款，但有了经银行承兑的汇票，在需要时，随时可以拿去贴现或者背书转让，促进贸易的发展。
信用证中不是也有不使用汇票的吗？即期付款的、和延期付款的信用证可以不用汇票
信用证下汇票是由受益人出具，但是，如果信用证为议付信用证，或付款信用证，那么，议付行或付款行在受益人交单相符的情况下，对受益人做了议付或付款，那么，议付行或付款行就取代受益人的地位，成为该信用证的收款人，所以，信用证项下如果需要提交汇票的话，则上述情况下汇票的出具人就可以是议付行或付款行。
信用证是开证行对受益人的有条件的付款承诺，即开证行是信用证的付款人。
说明他们非常的无聊。
以下的学院派解释可能对LZ有些帮助。
汇票是由一个人向另一个人签发的，要求及其或定期或在可以确定的将来时间，对某人或其指定人或持票人支付一定金额的无条件书面命令。
A bill of exchange is an unconditional order in writing addressed by one person to another signed by the person giving it requiring the person to whom it is addressed to pay on demand, or at a fixed or determinable future time a sum certain in money to or to the order of a specified person, or to bearer
现在除了那些污七八糟的国家还在做信用证之外，主流的欧美国家有几个用L/c的，唉～～
