Here we will guide you about the tips to write an overdue invoice letter:

1.Follow Up At The Right Time:

The right time to follow up with your clients is:

  • If your client is habitually paying a late fee, you must follow up right after an invoice is due.
  • If the client is new or not in the habit of paying a late fee, you can follow up after a week or two.
  • If the payment is due for a month, two months, or three months, you should follow up repeatedly.
  • If your client has a busy schedule, you should send an overdue invoice letter on weekends to grab the attention.
  • Another option for follow up is sending an overdue invoice on ‘Tuesday.’ According to the ‘Entrepreneur,’ it is the best time to send an invoice on Tuesday, before or after lunchtime.
  • If you have more than one client with overdue payments, then you should send them reminders at once to save your time and energy.

2. Add Invoice And Payment Details:

Adding details in your overdue invoice letter will help the clients to know the payment details, including:

  • Date and invoice number
  • Payment terms (late fee)
  • Amount owing
  • Reminders of previous invoice letters
  • Payment instructions (through links in emails)
  • Your contact details

3. Tailor The Language:

You need to change your language in an overdue invoice letter depending upon the time and situation. You can tailor the language accordingly:

1-15 days past due:

By keeping good relations with your customers, you can remind them of their due payment.

You need to be polite and gentle with them.

30-60 days past due:

You should stay professional but do remind your clients about the due payment in an affirmative way. Tell them that it’s too late in paying your dues.

90+ days past due:

At this point, you can hardly expect your due payment from the client. So you need to send an invoice to a collection agency for further processing.

Do inform your clients that if they do not pay the dues, their accounts will turn over to the collection agency, so be prepared. 

4. Late Fee Charges:

You should discuss the rules of late fees or overdue invoices to avoid any confusion in the future. You can set an amount or percentage you can demand as a late fee on their due payment.

Let’s say:

If a state charges 20% of interest, divide that number by 12 to get the monthly late fee percentage.

Not every business can charge a late fee because it may have some disadvantages that you should know.

5. Offer A Payment Plan:

If your client is not paying you an overdue amount within the notice period, you can offer a manageable payment plan. Where you can divide the total payment amount into parts of two or three. It will increase the chances of getting your payment from clients.

6. Be Polite:

How to Write an Overdue Payment Reminder Letter

It helps you in getting your payment as well as maintain your good reputation in the business world. You must add courtesy words (Thank you, Please) in your letters to leave a good impression on your clients.

7. Automate Reminders:

An ‘Invoicing Software’ helps send reminders to your clients on different days after the due date of payment. You just need to set the reminders, including one day after the due, 30 days, 60 days, and so on. You can also add a personal message with each of the reminders. This software automatically adds a late fee to the invoice total.

8. Enlist Help:

The last and final option is to seek help from collection agencies or legal counselors. If your client is not cooperating and resists paying your dues, you must take help from lawyers and collection agencies.

You can also find the liable collection agency online. You should send the last warning to your clients in which you must mention the collection agency and tell them that they will keep in touch.
