What is dunning management software?+

Dunning management software automates the process of recovering failed subscription payments. This includes retrying payments, sending email notifications to customers, and in some cases making phone calls to encourage payment method updates.

Which dunning software has the highest recovery rates?+

Tools with multi-channel recovery (email + voice + retries) like Rezoki typically achieve the highest rates (60-80%). Email-only tools like Churn Buster recover 40-60%. Retry-only tools like Stripe Smart Retries recover 20-30%.

Do I need dunning software if I use Stripe?+

Yes. Stripe Smart Retries is a good baseline but only recovers 20-30% of failures. A dedicated dunning tool adds email and voice outreach to recover the 40-60% of failures requiring customer action.

How much does dunning software cost?+

Ranges widely: free (Stripe Smart Retries), $50-$500/month (most tools), to 15-25% of recovered revenue (Gravy). Most SaaS companies find $50-$200/month tools provide the best value.

Can I use multiple dunning tools together?+

You can use Stripe Smart Retries (free) alongside one dedicated tool. Avoid running multiple email dunning tools simultaneously as they'll send duplicate emails. Choose one primary tool for customer communication.

What features should I look for in dunning software?+

Multi-channel recovery (email + voice), smart retry optimization, BYOSMTP for email control, historical scanning, customizable sequences, transparent audit trail, and flexible pricing without long-term contracts.
