Involuntary churn – the loss of subscribers due to failed payments or technical issues – is a silent killer of subscription revenue.
Many SaaS and subscription businesses focus heavily on product improvements and customer service to reduce voluntary churn. Yet, up to 40% of customer churn can happen involuntarily, without the customer ever intending to leave.
This hidden leak can cost companies an estimated 9% of their annual recurring revenue on average. In other words, you could be losing a full month’s worth of growth each year to failed payment issues.
Even worse, once a customer is lost to a payment failure, only about 5% ever resubscribe.
The good news? Involuntary churn is highly preventable with the right approach and tools.
What is involuntary churn?
Involuntary churn occurs when a customer’s subscription ends unintentionally, usually due to payment failures or other issues outside the customer’s control. In contrast to voluntary churn (when customers actively cancel their subscriptions), involuntary churn happens even when customers want to continue their service.
Essentially, these are happy customers who get cut off from your product because the payment couldn’t go through.
Common causes of involuntary churn include:
- Expired credit cards: The customer’s card has expired, and they haven’t updated the details.
- Insufficient funds: The charge was declined because the customer’s account didn’t have enough funds at the time.
- Declined transactions: The bank or card issuer rejects the charge due to suspected fraud, regional restrictions, or other processing errors.
- Technical issues: Payment gateway errors or integration glitches that cause a valid payment to fail.
- Communication breakdowns: The customer wasn’t aware their payment failed (missed emails or notifications), so they didn’t resolve it in time.
This is why involuntary churn is often called the “silent” or “hidden” revenue killer: it silently erodes your customer base and revenue without the usual red flags of dissatisfaction.
Why involuntary churn hurts your revenue
Losing customers who actually want to stay is painful for several reasons:
- Revenue loss: Involuntary churn directly cuts into your recurring revenue. Industry research shows failed payment churn can make up 20–40% of total churn for many subscription businesses.
- High customer acquisition cost (CAC) wasted: You’ve already spent resources to acquire and onboard these customers. When they churn involuntarily, that acquisition investment is wasted.
- Low reactivation rates: Unlike a voluntary cancellation (where you might win a customer back with improvements or incentives), involuntary churn often goes unresolved. Only ~15% of failed payments get recovered with basic retry and email attempts, and a mere 5% of customers will proactively resubscribe later if you do nothing.
- Customer experience damage: Involuntary churn can catch customers by surprise – suddenly losing access to a service they rely on. This can frustrate customers and erode trust.
- Hidden growth impediment: Because involuntary churn is less visible (customers aren’t explicitly contacting you to cancel), companies often overlook this “leak” in the bucket. They focus on acquiring new customers and reducing voluntary cancellations, while unknowingly losing a chunk of subscribers silently.
Strategies to reduce involuntary churn
Preventing involuntary churn requires focusing on payments and processes: making sure customer payments go through successfully, and intervening quickly when they don’t.
Smart payment retry logic
Retrying payments at better times often succeeds. Intelligent retry rules adjust attempts based on failure reason, card type, or timing, which can lift recovery rates by 15–25%.
2Checkout (now Verifone) automatically retries soft declines up to six times and recovers about 20% of transactions that would otherwise be lost. Varying intervals and times help capture even more revenue.
Account updater services
Expired or replaced cards drive much of involuntary churn. Account updater tools automatically refresh card details and can cut these failures by roughly 30%.
2Checkout’s account updater handles this behind the scenes and can lift retention by up to 40%, even identifying and updating expiring cards before the charge fails.
Multiple payment methods and currencies
Offering alternatives like debit, direct debit, PayPal, or digital wallets reduces friction when a card fails. Billing in the customer’s local currency also boosts approval rates.
2Checkout now Verifone supports 45+ currencies and local methods, which can raise authorization success by up to 25% and lower abandonment tied to unexpected currency issues.

Intelligent payment routing
Some processors perform better for specific regions or card types. Routing transactions through the most suitable gateway improves approvals, and using backup gateways on retries salvages additional sales. 2Checkout routes transactions dynamically and can add 2–5% to global approval rates, with far higher gains in markets that benefit from local routing.
Dynamic 3D secure
3D Secure helps where fraud risk or regulation requires it, but using it selectively avoids unnecessary friction. Dynamic application increases approvals in high-risk regions without hurting clean transactions. 2Checkout’s adaptive 3DS reduces false declines and the churn they create.
Proactive dunning & customer communication
Most customers do not notice a failed payment unless you tell them. Automated reminders via email, sms, or in-app messages, paired with a quick link to update payment details, significantly raise recovery.
2Checkout sends automated notices for hard declines, adding about a 1% uplift in renewals. Strong dunning processes can reach 85%+ recovery, far above the 15% achieved by simple single-email attempts.
Monitor, measure, optimize
Track your involuntary churn rate and payment recovery rate. Look for patterns by region, card type, or timing, then refine your retry schedule or add missing payment methods. 2Checkout’s reporting tools, including an authorization rate dashboard, give merchants visibility into what works and where to adjust.

Dynamic 3D secure & fraud tools
