Dunning refers to the process of contacting customers to recover overdue payments. It plays a critical role in maintaining cash flow for businesses, especially those in industries like subscription services, utilities, and financial lending.

The purpose of dunning isn’t just to collect payments. It’s also about maintaining positive customer relationships while encouraging accountability. When done effectively, it ensures that businesses recover unpaid invoices without damaging trust.

Imagine a streaming service like Netflix sending you a polite email about a failed payment. That’s a simple example of dunning in action.

The Dunning Process

Initial Reminder

The process begins with a friendly reminder sent soon after a payment is missed. This might be a polite email or SMS to inform the customer of their overdue balance.

For example, an email might say: “Hi [Customer Name], we noticed your payment of $50 for [Service] is overdue. Please check your account to complete the payment.”

Follow-Up Notices

If the payment is still not made, follow-up reminders escalate in urgency. Businesses might send multiple emails or even call the customer, providing clear details about the overdue balance and potential consequences if payment is not made.

Warning Notices

When the situation becomes more serious, customers are warned about potential penalties or interruptions to their service. For instance, a subscription-based service may notify users that their account will be temporarily suspended unless the payment is completed.

Final Steps

If the customer still doesn’t pay, businesses might take final actions, such as referring the account to a collection agency, cutting off services, or even pursuing legal action.

Types of Dunning Communication

Friendly Reminders

These are gentle and professional, intended to nudge customers into action without being overly aggressive. For example:
“Hello [Customer Name], your payment for [Product/Service] was due on [Date]. Please complete the payment soon to avoid service interruption.”

Firm Notices

If the first reminder doesn’t work, businesses use a firmer tone. These messages clearly explain the overdue amount and what will happen if it remains unpaid.

Final Warnings

These messages outline the consequences of non-payment, such as legal action or service termination. The language is more formal but still professional.

Automated Dunning Messages

Many businesses use automated systems to send scheduled reminders. Automation ensures consistency and reduces the workload for teams managing overdue accounts.

Why Is Dunning Important?

Unpaid invoices can hurt cash flow. Dunning helps businesses recover lost revenue efficiently, ensuring financial stability.

Challenges in the Dunning Process

Balancing Tone and Frequency

Finding the right balance between being polite and firm is critical. Too many reminders can annoy customers, while too few may lead to unpaid accounts.

Customer Miscommunication

Sometimes, customers claim they didn’t receive reminders. Clear communication and updated contact details help avoid this issue.

Inaccurate Billing Information

Errors in invoices or account details can create disputes, delaying payments.

Automation Errors

Automated systems occasionally send reminders to customers who’ve already paid, leading to frustration.

Legal Risks

Businesses must ensure their dunning process complies with local laws to avoid claims of harassment or unfair practices.

Best Practices for Effective Dunning

Personalize Communication

Address customers by their names and include specific details about their overdue balance. Personalized messages feel less transactional and more professional.

Send reminders through emails, SMS, in-app notifications, or even phone calls. This increases the chances of reaching customers.

Automate Where Possible

Tools like Stripe, Recurly, and Chargebee simplify the process by sending automated, timely reminders based on customer behavior.

Provide Easy Payment Options

Simplify the payment process by including links to payment gateways or step-by-step instructions. Customers are more likely to pay when it’s convenient.

Stay Professional and Polite

Focus on solving the issue instead of being overly aggressive. A polite tone helps maintain the customer relationship.
