用英语如何标准表达定金和提单？

问题：最近和一个新客户谈好的付款条件是，20%定金，50%见提单复印件，15%是到港后30天内，最后15%是到岗后60天内付钱。请问用英语如何标准表达上述条款？

回答：以下是一种标准的英文表达方式：

1. Payment Terms:

   - 20% deposit upon confirmation of order.

   - 50% upon presentation of the copy of the bill of lading.

   - 15% within 30 days after the arrival at the port.

   - Final 15% within 60 days after the arrival at the port.

2. Payment Method:

   - Preferred method of payment: wire transfer/direct bank transfer.

Please note that it is always recommended to consult with a legal professional or contract expert to ensure that the payment terms accurately reflect your intended agreement and comply with any applicable laws and regulations.
