What is payment recovery?+

Payment recovery is the process of collecting failed subscription payments. This involves retrying the payment, notifying the customer to update their payment method, and following up through various channels until the payment succeeds or the subscription is canceled.

How much revenue can payment recovery tools save?+

With optimal tooling, you can recover 60-80% of failed payments. For a SaaS with $500K ARR and a 5% monthly failure rate, that's $15,000-$20,000 per year in recovered revenue.

What's the best free option?+

Stripe Smart Retries — it's free and automatic. However, it only recovers 20-30% of failures. For serious recovery, combine it with a paid tool like Rezoki for the best results.

Which tool is best for startups?+

Rezoki offers the best feature-to-price ratio for startups: AI voice, email, and retries at an affordable starting price. Historical scanning also lets you recover revenue from past failures immediately.

Do I need to change my billing platform?+

No. Tools like Rezoki, Churn Buster, and Butter work with your existing Stripe setup via webhooks. Only billing platform add-ons (Chargebee Retention, Recurly Dunning) require platform commitment.

Which recovery channel is most effective?+

Smart retries recover transient failures. Email recovers customers who need to update cards. Voice calls recover high-value accounts that ignore email. The best approach uses all three — which is what Rezoki uniquely offers.
