业务员在审核信用证后，如果发现有不符合合同或不利于公司安全收款的条款，应及时联系客户通过开证银行对信用证进行修改。修改信用证的要求应尽可能一次性、具体、明确地提出，以避免多次改证，耽误时间。
要求客户修改信用证的邮件内容一般包括以下三个部分。
(1)感谢对方开来的信用证(也可开门见山，直入主题)。
(2)列明不符合合同或不利于公司安全收款的条款并说明如何修改。
(3)感谢对方合作，并希望修改后的信用证早日开出，有利于继续履约。示例如下。 Dear Mr. Jones,
We have received your L/C No.121/99 issued by the Yemen Bank for Reconstruction & Development for the amount of $19720 covering 1600 dozen Man's Shirts. After reviewing the L/C, we find that transshipment and partial shipment are not allowed.
As direct steamers to your port are difficult to find, we have to ship via Hong Kong more often than not. As to partial shipment, it would be our mutual benefit because we could ship immediately of whatever we have on hand instead waiting for the whole lot to be completed.
We, therefore, are writing this afternoon, asking you to amend the L/C to read:“Transshipment And Partial shipment Allowed”.
We shall be glad if you see to it that amendment is cabled without any delay, as our goods have been packed ready for shipment for quite some time. Yours sincerely, xxx
