Dunning letter management: Optimize your collections strategy

For finance leaders managing accounts receivable, dunning letters represent a critical touchpoint in the collections process. These payment reminders, also called collection letters, serve as essential communication tools that can significantly impact your cash flow, operational costs, and customer relationships. However, many organizations still rely on manual, time-intensive approaches to dunning management that fail to deliver optimal results.

As the accounts receivable landscape evolves, modernizing your dunning letter strategy through automation offers a powerful opportunity to control costs, accelerate cash flow, and improve customer satisfaction. Automated dunning systems transform what was once a labor-intensive process into an operation that delivers measurable business outcomes.

What is a dunning letter and why it matters

A dunning letter is a formalized payment reminder sent to customers with outstanding invoice balances. These communications typically follow a progressive sequence, beginning with gentle dunning reminders about unpaid invoices and potentially escalating to more urgent notices as the payment becomes increasingly overdue.

For finance leaders, dunning management directly impacts your company's financial health. When implemented strategically, dunning letters:

• Reduce Days Sales Outstanding (DSO) by encouraging timely payments.
• Preserve valuable customer relationships through professional, consistent communication.
• Free your team from manual, repetitive tasks to focus on higher-value activities.
• Provide documentation of collection efforts for internal tracking and analysis.

One national plumbing/HVAC distributor partnered with Billtrust to address inefficiencies in their collection processes. After implementing Billtrust's dunning letter solution, they experienced a 20% increase in cash receipts while achieving match rates of over 60% by envelope and 83% for line items. Their Regional Credit Operations Manager noted, "With Billtrust, my team no longer has to focus on manual processes and can dedicate their time to relationship building as we continue to grow."

Elements of a dunning letter

The most successful dunning letters combine several key elements to maximize productivity while maintaining positive customer relationships. Finance leaders should ensure their dunning communications include:

Clear payment terms and instructions

Every dunning letter should clearly state the outstanding amount, invoice numbers, original due dates, and specific instructions for making payment. Removing friction from the payment process increases the likelihood of prompt resolution.

Appropriate tone based on aging stage

The tone of your dunning communications should evolve appropriately as invoices age. Initial notices might be friendly reminders, while later communications may convey increasing urgency. However, maintaining professionalism at every stage is essential for preserving customer relationships.

Personalization that strengthens relationships

Generic dunning notices often get overlooked. Personalizing communications with relevant details about the customer's specific situation demonstrates attention to their account and increases response rates.

Compelling call-to-action

Each dunning letter should include a clear, prominent call-to-action that guides customers toward resolution. Whether directing them to an online payment portal or providing contact information for your collections team, the path forward should be unmistakable.

The large plumbing/HVAC distributor mentioned earlier implemented these principles through Billtrust's collections solution. By optimizing their dunning process with personalized communications and clear payment options, they saved significant time and resources while providing their customers with 24/7 invoice access through a self-service portal.

Best practices for dunning letter sequences

The sequencing of dunning communications can dramatically impact their performance. Finance leaders should consider these best practices when structuring their dunning process:

Timing strategies for different aging buckets

Develop a systematic schedule for when dunning letters are sent based on aging categories. This might include:

• Friendly reminders 2-3 days before the due date.
• Initial notices 1-5 days after the due date.
• Follow-up communications at 15, 30, and 45+ days past due payments.

Escalation approaches that maintain professionalism

As invoices age, communications should reflect increasing urgency while remaining professional. This might include escalating from email reminders to more formal letters, eventually involving higher-level contacts at the customer organization.

Multichannel strategies

The most optimized dunning letter processes leverage multiple communication channels based on customer preferences and response patterns. Combining email, traditional mail, and even SMS notifications creates multiple touchpoints that increase visibility.

AI-enhanced sequence effectiveness

Modern AI capabilities transform traditional dunning processes by analyzing payment behaviors and recommending optimal timing, channels, and messaging for each customer segment. This data-driven approach significantly improves response rates.

The plumbing/HVAC distributor's success story demonstrates the power of these practices. By implementing dunning sequences through Billtrust's solution, they achieved a 20% increase in cash receipts while significantly reducing the manual labor previously required for payment reminders.
