answer: #Person2# wants to make payment for the order by documentary collection to decrease the cost of the import but #Person1# refuses and suggests consulting #Person2#'s bank and seeing if they will reduce the required deposit to a minimum.
documents: #Person1#: Have you got any specific proposal about the terms of payment?
  #Person2#: I wonder if we can make payment for this order by documentary collection.
  #Person1#: I'm sorry to say the only term of payment we can accept is 100 % irrevocable letter of credit payable against shipping documents.
  #Person2#: But our order this time is very large. To open an L / C for such a large amount at a bank is costly. Can you be a bit more flexible and bend the rule a little?
  #Person1#: I'm afraid not. We insist on a letter of credit, because as seller, we also have the problem of funds being tied up.
  #Person2#: To be frank, a letter of credit would increase the cost of my import. When I open a letter of credit with a bank, I have to pay a deposit. That will tie up my money and add to my cost.
  #Person1#: Consult your bank and see if they will reduce the required deposit to a minimum.
