最近一直头疼催款问题，和大家交流一下吧：

SAMPLE 范文

　　Dear ___:

　　I am afraid your failure to settle your account, which is over due for more than five months, will leave us with no alternative but resort to legal proceedings.

　　This is to notify you that unless we receive your check for $9,550.50 by June 10, we will place your account in the hands of our attorneys for collection.

　　Yours sincerely,

　　___[name]
