（1）subject: Demanding Overdue Payment
As you are usually very prompt in settling your accounts, we wonder whether there is any special reason why we have not received payment of the above account, already a month overdue.
We think you may not have received the statement of account we sent you on 30th August showing the balance of US$ 80,000 you owe. We send you a copy and hope it may have your early attention.
（2）Subject: Urging Payment
Not having received any reply to our E-mail of September 8 requesting settlement of the above account, we are writing again to remind you that the amount still owing is US$ 80,000. No doubt there is some special reason for delay in payment and we should welcome an explanation and also your remittance,
（3）Subject: Insisting on Payment
It is very difficult to understand why we have not heard from you in reply to our two E-mail of 8th and 18th September for payment of the sum US$ 80,000 you are still owing. We had hoped that you would at least explain why the account continues to remain unpaid.
I am sure you will agree that we have shown every consideration and now you fail to reply to our earlier requests for payment, I am afraid you leave us no choice but to take other steps to recover the amount due.
We are most reluctant to do anything from which your credit and reputation might suffer and even now we prepare to give you a further opportunity to put the matter right.We therefore propose to give you 15 days to clear your account,
(1)The following items totaling $4000 are still open on your account.
(2)It is now several weeks since we sent you our first invoice and we have not yet received your payment.
(3)I’m wondering about your plans for paying your account which,as you know,is now over 40 days ast due.
(4)We must now ask you to settle this account within the next few days.
Subject: Bank Draft Payment
The goods under Contract No.555 was delivered here in good order and condition and we are quite satisfied with it.
Please find a Bank Draft to the value of US$ 80,000 for payment of your Invoice No. 1223 sent by airmail. An acknowledgement in due course will be appreciated.
Subject: Asking for Deferred Payment
Your Invoice No.1223 for US $ 80,000 worth of goods supplied on 20th July is due for payment at the end of this month. Most unfortunately, a fire broke out in our warehouse last week and destroyed a certain part of valuable consignment. Our claim is now with the insurance company, but it is unlikely to be met for another three or four weeks and until then we are faced with a difficult financial situation. I am therefore writing for permission to defer payment of your invoice until the end of September.
As you know, my accounts with you have always been settled promptly and it is with the utmost regret that I am now forced to make this request. I hope, however, that you will find it possible to grant it. In doing so you would render me a service I should never forget.
