    Tips to Follow

    Some tips to follow while writing the past due letter are:

    1. Mention every detail

    You should mention every detail relating to the invoice as well as the payment methods. These details may include:

    • Invoice number
    • Amount owed
    • Payment terms
    • Payment instructions and
    • Contact information, among others.

    2. Tailor the language according to the occasion

    Usually, the language you use plays a major role in your relationship with your clients. According to experts, the language used varies depending on the period taken. For instance, if the amount is 15 days past due, it’s wise that you use polite and friendly language. Using a gentle and polite language will facilitate a positive relationship, which will, in turn, encourage them to pay.

    If the amount owed is 60 days past the due date, then the language to use should be able to demonstrate urgency. Since the amount is overdue, don’t be shy to mention so.

    However, things should take a different turn if the client stays up to 90 days without making payments. While it’s still important to maintain professionalism, you can remind the client that necessary legal actions may be taken if they don’t respond promptly. Among the actions likely to be taken is engaging a debt collection agency.

    3. Late payments penalties

    Also, you can mention in the past due letter that you intend to impose late payment penalties. Oftentimes, the penalty is charged at a specific percentage of the total amount owed. However, it’s important to note that once you’ve decided to impose a late payment penalty, it can sour your relationship with the client.

    4. Automate the reminders

    One of the best ways of sending past due letters is through automated reminders. You can, therefore, set a reminder to send your letters at a specific time interval.

    5. Enlist help

    At the end of your letter, you can notify the client that you are willing to seek legal help either from an attorney or collection agency to help settle the debt. Through this, they will see the urge to commit themselves towards settling the debt.


    Writing an email past due letter is more or less the same as the text version. However, the difference occurs in the header. Instead of writing your name and address details, the email letters do lack this part. Instead, you will start your letter by including the subject line. Again, instead of a signature, you can simply include your initials for the electronic letters. Otherwise, the rest of the information should remain the same as the text versions.
