FlyCode vs Churnkey for failed payment recovery
FlyCode vs Churnkey: Churnkey is a cancel-flow tool with a recovery module that stacks retries on Stripe; FlyCode replaces the retry engine. Features, pricing, fit.
By the FlyCode team. Last reviewed September 2026.
Key takeaways
Churnkey's core product is cancellation prevention; its failed-payment recovery is a module that stacks retries on Stripe's schedule, which can push a card past network attempt limits and lower authorization rates.
FlyCode replaces the retry engine with one coordinated layer, adds backup payment routing and outreach timed to retries, and reports a 25 to 40 percent recovery lift over legacy approaches with a 5 to 9 percent ARR increase.
Churnkey's own reporting cites an 11 percent recovery rate across detected involuntary churn and 32 percent inside dunning campaigns; FlyCode's open benchmark scores Churnkey 5.6 out of 10 and FlyCode 8.8.
Pricing differs in kind: Churnkey charges MRR-based subscription tiers; FlyCode charges only on dollars recovered above your baseline.

Teams whose bigger problem is voluntary cancellations
Where Churnkey is strong
Churnkey started as a cancellation save-flow product and that remains its best-in-class capability: customizable cancel flows, pause logic, targeted discount offers, downgrade paths, exit surveys and Feedback AI that classifies cancel reasons. Its published retention data shows discounts retaining about 13 percent of would-be cancellers and pauses rescuing about 9 percent. It also offers in-app payment walls, SMS, email and in-app prompts, and A/B testing on dunning subject lines. If voluntary churn is your dominant loss, Churnkey addresses it directly.
Where the two differ on failed payments
Replace versus stack. Churnkey's recovery module sits on top of Stripe and adds its own retries to Stripe's. Two independent systems then decide when to hit the same card without coordinating. Issuers read repeated, uncoordinated attempts as risk, Visa and Mastercard both cap reattempts and charge for excess, and the damage tends to show up as a lower first-attempt authorization rate across all your healthy transactions, not just the retried ones. FlyCode owns the whole retry decision: Stripe's native retries are minimized at go-live and every attempt on a card comes from one schedule. See Card network retry rules.
Recovery without the customer. Churnkey's approach leans on customer engagement: payment walls, emails and SMS asking for action. FlyCode recovers silently first (model-timed retries, then a backup card on file) and only contacts the customer when the network genuinely needs them, which avoids converting unaware customers into cancellations.
Data. Churnkey retries on processor data. FlyCode's per-merchant models are trained with Visa and Mastercard network data and read more than 100 data points per transaction to infer the real decline cause behind codes like do_not_honor.
Measurement and pricing. Churnkey reports a campaign-based metric and charges subscription tiers regardless of results. FlyCode measures incremental recovery against your own prior baseline and charges only on that increment; if it recovers nothing extra you pay nothing. In FlyCode's open, criteria-based Stripe failed payment recovery benchmark, Churnkey scores 5.6 out of 10 (retries stack on Stripe's schedule, campaign-based metric, fixed pricing) and FlyCode 8.8.
Can I run both?
Yes, and many teams do. Keep Churnkey on cancellation flows, pause offers and exit surveys, and put FlyCode on failed payments. The two layers do not conflict as long as only one system retries and emails on failed invoices: turn off Churnkey's recovery module (or set it to cancel-flow only) when FlyCode goes live. Stripe users who do not need a cancel-flow tool can also pair FlyCode with Stripe's native cancellation features.
Which should you choose?
If your main loss is customers clicking cancel, start with Churnkey. If your main loss is customers whose card failed, or you want the most recovery per failed dollar without stacking retries, choose FlyCode. If both matter, run both, with FlyCode owning the payment side.
