From: Chief Accountant Date: 5 October, 2004
To: Managing Director Ref: MA/501/AC
Subject: Edmond Brothers, Bicycle Retailers
I have received a letter from Edmond Brothers dated 20th September. They would like to open an account with us and pay us quarterly on receipt of a statement from us.
I am satisfied that they are credit-worthy, and will write to them, if you agree, granting the credit terms they ask for. They have been our customers for three years and have always paid promptly on receipt of our invoices. They have recently opened a bank account, for which we were able to supply them a good reference. It would be easier for us and for them if they did not have to make separate payments each time a purchase was made.
Please let me know the decision.
