Dear [NAME, ex. John Smith],
I believe there has been a slight mistake.
I have just received your [DOCUMENT, ex. your account summary for June]. Unfortunately, I am unable to reconcile your invoices to the $[AMOUNT] figure you state as my account balance. My records indicate as follows:
[LIST INVOICES AND PAYMENTS, ex.
Payment, Check #123, 5/1/98 -250.00
Payment, Check #123, 5/1/98 -200.00
I have taken the liberty of enclosing copies of the above invoices and checks. Please check your records to determine the source of the discrepancy and call me at XXX-XXXX once the difference has been reconciled.
[YOUR NAME, ex. Jill Jones]
