Dunning

What is Dunning?

Dunning is an automated process used by businesses to remind customers of their unpaid invoices and other debts. In accounting, the dunning process tracks and proactively manages accounts receivable to achieve greater revenue assurance. This process, also known as debt collection or credit control, can include activities such as calling customers and sending past-due notices by email.

In billing operations, dunning helps companies manage their cash flow by minimizing late payments from their customers. It involves regularly reminding customers of their unpaid invoices and ensuring that payments are made on time.

To do this efficiently, without error, and with minimal manual effort, most businesses automate the dunning process. Automated dunning systems send reminders to customers about their outstanding balances and prompt them to make on-time payments.

The Importance of Dunning in Subscription Billing

In subscription-based businesses, maintaining consistent cash flow is critical, and the dunning process plays a key role. Dunning ensures that customers are reminded of overdue invoices or failed payments in a structured, automated way, reducing the risk of revenue leakage and service disruptions.

Because subscriptions often involve recurring payments, a single failed transaction can quickly escalate into multiple missed payments if not addressed promptly. Automated dunning workflows help businesses manage these scenarios efficiently by sending timely reminders, notifying customers of payment issues, and offering simple ways to update payment methods.

Dunning also contributes to a positive customer experience. By providing clear, professional, and consistent communication, businesses can encourage prompt payment while maintaining trust and minimizing friction. This is especially important in subscription models, where long-term relationships and customer retention are just as valuable as the immediate revenue.

When integrated into a unified revenue platform that connects CPQ, billing, and customer management, dunning becomes even more effective. The system can automatically trigger reminders based on subscription terms, payment history, or failed transactions, ensuring that both the business and the customer stay aligned throughout the billing lifecycle.

Dunning in subscription billing is not just about chasing overdue payments; it is a strategic tool to safeguard revenue, maintain healthy cash flow, and foster long-term customer relationships.

The Dunning Process

The dunning process can be broken down into six main steps.

Dunning Process

Monitor Data

Track and analyze customer invoices and payment histories in real time.

Flag Delinquencies

Automatically identify accounts with unpaid or overdue balances.

Send Dunning Letters

Dispatch automated reminders requesting immediate payment.

Escalate Outreach

Have collections agents call or email unresponsive customers.

Negotiate Terms

Create flexible payment plans for customers experiencing hardships.

Involve Collections

Hire a third-party agency to recover long-overdue debt if ignored.

Once an organization collects the required payments from its customers, it can update its records and close the accounts receivable.

Benefits of an Effective Dunning Process

A successful dunning process makes it easy for organizations to close their books, improve internal cash flow, and reduce the time spent managing accounts receivable.

It also helps organizations to maintain better relations with their customers by making sure that all debts are paid on time. This can lead to increased customer satisfaction and loyalty as customers know they will be reminded when payments are due.

Improve Customer Retention

A 5% increase in customer retention can increase company revenue by 25-95%. And it is 6-7 times more expensive to acquire a new customer than to retain an existing one.

An effective dunning process can help companies retain customers who are at risk of churning or leaving. By regularly reminding customers about their outstanding balances, companies can proactively manage customer debt and retain customers who have overdue payments.

Avoid Failed Payments

Involuntary churn—also known as involuntary customer turnover—is when a customer’s subscription or service is canceled or terminated by the provider due to payment failure.

It occurs when payment methods expire, decline, or are removed from the account without warning.

This can happen for several reasons that vary from company to company.

• The company may not accept the customer’s payment type. This is common with credit card payments, international transfers, or payments via third-party services (e.g., PayPal).
• The payment information may be out of date or incorrect. This can cause failed payment attempts when customers forget to update their billing details or credit card numbers change without the company being notified.
• A payment slipped through the cracks due to financial or administrative error (i.e., revenue leakage). This is common in organizations with manual client billing processes or irregular payment cycles.

An automated dunning process can help to reduce the risk of failed payments and minimize involuntary churn.

An automated dunning process can help to reduce the risk of failed payments and minimize involuntary subscription churn. Regularly sending reminders encourages customers to update their payment information on time and ensures that no payments slip through the cracks.

Better Customer Communication

By implementing dunning levels (i.e., criteria for how often customers are contacted when payments are due), companies can customize the frequency of their customer communication.

This helps to ensure that customers receive reminders about payment deadlines without being inundated with too many emails or messages.

It also allows companies to tailor the content and tone of different dunning levels to fit the customer’s situation (e., companies can clearly communicate their payment terms and late fees to customers.

Dunning letters also provide customers with helpful payment information, such as the due date, amount due, and contact details for the accounts receivable team.

Dunning Automation Best Practices

When managing the billing process for clients and customers, organizations should stay compliant with laws and regulations, maintain customer relationships, and maximize financial gains.

To achieve these goals, organizations should consider the following best practices for effective dunning management:

Reduce Failed Transactions

Reducing involuntary churn is one of the easiest and fastest ways to improve overall churn within a company.

According to research from Recurly, the average customer churn rate is 5.57%. Of that, the average involuntary churn rate is 1.98%.

With an automated dunning system, companies can reduce their involuntary churn rate by ensuring that payment information is up to date and all payments are settled on time.

In the case of subscription businesses, organizations should also consider automating the cancellation process so that customers can easily cancel their services on time without having to contact the company directly.

Automate Dunning Emails

Dunning emails are an effective way to remind customers of their payment deadlines and provide them with relevant payment information.

When setting up email templates, remember the following:

• Set up alerts/reminders to notify customers of overdue payments or payment failure
• Include the payment amount and due date and contact details for customer support
• Make sure the content and tone of the email are both clear and professional.
• Include clear guidelines on late payment penalties or fees
• Offer payment options that are convenient and secure for customers within the emails.
• Set dunning levels to create cadences based on customer payment history
• Utilize customer segmentation to customize emails for each customer

Automating dunning emails ensures timely reminders are sent to all customers and reduces the risk of unpaid invoices.

Automate the Accounts Receivable Process

An automated accounts receivable process helps to streamline the billing and collection process.

It allows companies to set up payment conditions, automate dunning emails, track payments in real-time, update customer information quickly and accurately, and generate reports for financial analysis.

About half of accounting tasks can be automated using current technology, and accounts receivable processes like collecting accrued revenue and reconciling customer payments are a great place to start.

Use the Right Messaging

When sending dunning emails or letters, make sure to craft the message in a way that will capture the customer’s attention without putting them off.

• Avoid using accusatory language and instead focus on the value you provide to the customer by reminding them of their payment deadline.
• Make sure to include clear instructions for customers to update their payment information or make a payment online.
• Let customers know they can contact your accounts receivable team if they have any questions or concerns.

The same is true for manual phone calls—keep the conversation polite, friendly, and professional. Even if a customer is consistently or dramatically late on payments, try to address the issue with respect and understanding.

Improve the Customer Experience

A positive customer experience is essential for any business. When customers are treated with respect and courtesy, they are more likely to make their payments on time and continue doing business with the company.

To improve the overall experience, organizations need to create customer-centric processes like:

• Setting up a customer payment gate that allows customers to manage their accounts, view invoices, and make payments.
• Providing helpful payment reminders and notifications.
• Making sure customer support staff are well-trained with the right knowledge and skills to address payment-related inquiries.
• Creating incentives for customers who pay on time or use preferred payment methods.

Improving the customer experience helps companies reduce their involuntary churn rate and improve customer relationships.

Dunning Automation: The Revenue Recovery Engine of Billing Software

While billing software is responsible for generating invoices and recording payments, its most critical role in protecting revenue is dunning automation. Instead of forcing accounting teams to manually hunt down past-due accounts, modern billing platforms act as an automated, proactive defense system against revenue leakage and involuntary churn.

When a payment fails or an invoice goes ignored, billing software manages the entire recovery lifecycle through dedicated dunning features:

• Intelligent Payment Retries (Smart Retries): Instead of giving up after a single card decline, the software uses data-driven algorithms to retry the payment at optimal times (e.g., aligning with common payday cycles or banking hours) to increase the likelihood of a successful transaction.
• Automated Escalation Workflows: The system replaces manual, awkward collections emails with a scheduled series of highly targeted reminders. These sequences gradually escalate in tone, from a gentle “credit card expiring soon” alert to a firm notice regarding potential service suspension.
• Proactive Pre-Dunning Alerts: The software monitors customer accounts for upcoming points of failure, such as credit cards expiring in the current month, and prompts the user to update their details before a billing attempt fails.
• Self-Service Billing Portals: Dunning communications include direct links to secure, personalized payment gates. This allows customers to instantly update their payment methods or pay any outstanding balance without contacting customer support.
• Grace Period and Access Management: The platform automatically coordinates with your product or service to handle grace periods (keeping the service active for a set window) or lock accounts if the dunning sequence concludes without a successful payment.
• Dunning Analytics and Analytics Reporting: Financial teams can track the exact ROI of their recovery efforts by monitoring metrics such as dunning recovery rates, the average days to collect past-due revenue, and the reasons behind credit card declines.

Reducing Churn for Subscription and Recurring Revenue Models

By automating the dunning process, subscription businesses can safeguard their bottom line against a massive hidden profit killer. Industry data from Baremetrics and Chargebee shows that the average subscription company loses 8% to 15% of its recurring revenue to payment failures. Furthermore, according to ProfitWell, up to 40% of a company’s total churn is involuntary, meaning automation can successfully claw back a significant portion of lost revenue from customers who never actually intended to cancel.
