Dear Felix
This debtor has not responded to our requests for payment. Our only alternative now is the actual placing of the account for collection.
As a final courtesy to this firm, we ask that you take no drastic steps toward collection until [date]. If we receive payment in full by this date, we will notify you to cancel the claim. Otherwise, you are to proceed in any manner you deem advisable to collect our money.
A statement of account is attached and a copy of this letter is being sent to the debtor so that they will have ample time to pay before the expiration date.
