White intends to order some products from Smith, which is the background. Here is part of the conversation below:
White: When will the goods reach me? Smith: We could ship your order within ten days upon receiving your payment.
White: So yo require payment in advance? Smith: Yes. You could transfer the payment into our bank account or open a letter of credit in our favor.
What does the underlined part mean? Thanks for help.
