What are Invoice Dunning Letters?

Professional letters, known as “dunning letters,” are used to remind clients of unpaid bills and persuade them to pay their accounts. They are an important stage in the collection process since they politely but forcefully remind clients to pay on time.

Challenges of Manual Dunning Letters

Traditionally, sending dunning letters has been a manual process, often involving:

Time-consuming Creation

Creating customized letters for every past-due invoice can take a lot of effort, particularly when you have big customers.

Inconsistent messaging

It can be difficult to keep a solid, professional tone when writing several letters at once.

Send-out delays

 Sending out dunning letters might be delayed by manual operations, which can hinder collection efforts.

Ineffective follow-up

It takes a lot of work to keep track of individual letters and start the proper follow-up procedures for various infraction levels.

Steps to Automate Invoice Dunning Letters

Automation of invoice dunning letters is straightforward and uses the right tools and approach. Here’s a step-by-step guide.

Choose an Automation Solution

Various automation tools are available, including accounting software with dunning features, collections software, and workflow automation platforms. Choose a solution that meets your budget, ease of use, scalability, and integration capabilities.

Identify Dunning Levels and Triggers

Determine different dunning levels based on the overdue period (e.g., 15 days late, 30 days late, 60 days late). Create triggers that automatically send dunning letters for each level.

Creating Dunning Letter Templates


Create dunning letter templates that are professional and firm at each level. The templates should include.

  • A clear and concise subject line.
  • Professional greeting addressing the customer by name.
  • This is a friendly reminder regarding the amount and deadline for the unpaid invoice.
  • A respectful request for action demanding prompt payment.
  • Details about the various payment options.
  • Implications for persistent nonpayment (expressed formally).
  • Please provide details so we can contact you if you have any more questions.

Personalize Templates

Although it’s not always essential, consider adding some personality to the templates. This can entail referencing certain invoice data or presenting alternate payment options.

Test and Refine

Use sample invoices to examine the automated system thoroughly before implementing it. This guarantees that the triggers work as intended and that the templates produce neat, formal letters.

Monitor and Adjust

Once your automated dunning procedure is in place, monitor its effectiveness. For every degree of criminal conduct, examine data on response rates and collection success. Using this data, modify templates, schedules, or triggers to maximize your collection strategy.

Additional Considerations


Once your automated trick process is up and running, monitor its efficacy. Review response rates and collection success statistics for each level of criminal activity. Based on this data, make changes to schedules, triggers, or templates to optimize your collecting strategy.

Payment Options

Provide a variety of payment options (e.g., credit card, debit card, online payment portals) so that clients may easily pay for their unpaid invoices.

Customer Communication:

Keep lines of communication open with your clients. Answer questions promptly and assist in resolving payment-related concerns.


One of the most effective ways to increase cash flow, simplify collections, and enhance financial health is to automate invoice dunning letters. Businesses can focus on core operations while guaranteeing prompt recovery of outstanding invoices by putting in place a well-defined automation strategy.
