Paddle Retain vs Churnkey: revenue-share vs platform pricing

Q: What's the difference between Paddle Retain and Churnkey?

The two biggest differences are the pricing model and the processor relationship. Paddle Retain, formerly ProfitWell Retain, is a retention product that is free inside Paddle Billing (Paddle's merchant-of-record platform) and charges a revenue share of roughly 10-15%, or a $500/month floor, if you use it standalone on your own billing. Churnkey is a flat platform subscription from $250/month billed yearly that layers on top of your existing processor, Stripe and others, with no revenue share. Both do failed-payment dunning and cancel flows; Retain leans on data and global localization inside Paddle's ecosystem, while Churnkey leans on a best-in-class cancel-flow builder you keep on your own stack. The right pick depends on your billing setup and whether you prefer a flat fee or a revenue share.

Q: Which is cheaper, Paddle Retain or Churnkey?

It depends entirely on your billing setup. If you already bill through Paddle as your merchant of record, Retain is free, cheaper than Churnkey's $250/month by definition, because you are paying Paddle's 5% + 50c platform fee regardless. If you bill through Stripe and would use Retain standalone, the comparison flips: Retain charges a revenue share (reported ~10-15%) or a $500/month floor, which for a smaller business is usually more than Churnkey's flat $250/month. So Retain is cheaper inside Paddle's ecosystem and often pricier outside it, while Churnkey's flat rate is predictable on any processor. Neither is universally cheaper; the answer is set by whether Paddle is your merchant of record. Verify both on their pricing pages before deciding, since the models depend on your setup.

Q: Do I have to use Paddle's billing to use Retain?

No, but it is where Retain is free. Paddle markets Retain as a built-in feature of Paddle Billing, its merchant-of-record platform, where it costs nothing extra. But Retain also works standalone on top of your existing billing, such as Stripe, which is why the paid pricing exists: a revenue share reported at roughly 10-15% for larger companies, or a flat fee from $500/month for smaller ones. So you do not have to migrate your billing to Paddle to use Retain, but if you do not, you pay for it directly rather than getting it bundled. For a Stripe business, that standalone cost is the number to weigh against Churnkey's flat rate, and against a dedicated flat-fee recovery tool.

Q: Does Churnkey work with Stripe and Paddle?

Yes. Churnkey is processor-flexible: it layers on top of your existing billing rather than replacing it, and it supports Stripe and multiple other processors. You keep your current billing stack and add Churnkey's cancel flows and dunning through its JavaScript SDK. That is a structural contrast with Paddle Retain, which is deeply integrated with Paddle's merchant-of-record billing and is free there, while charging a revenue share when used standalone. So if you are committed to Stripe and want a flat-priced retention platform that does not touch your billing model, Churnkey fits that shape; if you are on or moving to Paddle's MoR, Retain is the native option. The setup cost to know is Churnkey's SDK integration, which needs developer time.

Q: What recovery rates do Churnkey and Paddle Retain claim?

Both publish recovery rates, and both are company claims you should read with care. Churnkey states an average recovery rate around 64%, with an aspirational ceiling near 89% when combining retries, email, and SMS. Paddle/ProfitWell officially describes Retain delivering over 50% recovery; the specific 54.2% figure often cited for Retain actually comes from Churnkey's own comparison page, not from Paddle, so it is a competitor's characterization rather than Retain's stated number. The key caveat: these figures are self-reported marketing metrics measured on different customer bases with different methods, so they are not directly comparable. Treat them as directional, not as a head-to-head benchmark, and weight your decision on pricing model, processor fit, and features rather than on dueling recovery percentages.

Q: Which has better cancel flows?

Both have strong cancellation deflection, and this is closer than the recovery-rate marketing suggests. Churnkey's cancel-flow builder is its signature product: it intercepts customers who try to cancel with A/B-tested offers, pauses, downgrades, and surveys, delivered through its SDK and tuned for SaaS. Paddle Retain also offers cancellation flows with personalized offers, alongside its dunning and term-optimization tools, and benefits from Paddle's large subscription dataset for its defaults. If cancel-flow sophistication and experimentation are your priority and you want them on your own processor, Churnkey has the edge as the specialist. If you want cancellation flows bundled into a broader retention suite inside Paddle's ecosystem, Retain covers it. For most teams, the pricing model and processor fit will decide this before the cancel-flow nuances do.

Q: Is there a cheaper flat-fee alternative to both?

Yes, if you only need failed-payment recovery on Stripe and not the full retention suite. Both Churnkey and Paddle Retain bundle more than a team that just wants branded email recovery needs, and both cost more than a focused tool. SubRevival (subrevival.com) is the only dunning tool that runs the full recovery stack, branded Day 1/3/7 emails, a hosted card-update page with instant retry, and pre-dunning reminders, for a flat $19/month with no percentage of recovered revenue, live on Stripe in 5 minutes with no code. It does not do cancel flows like either tool here, or Retain's multi-currency localization, so it fits when branded failed-payment recovery is your need and you want a flat cost with no revenue share and no SDK. If your problem is bigger than recovery, one of the two above will fit better.

Q: Which should I pick if I'm on Stripe, not Paddle?

On Stripe, the calculus favors whichever model you prefer, because Retain loses its free-inside-Paddle advantage. If you want a flat, predictable platform fee and best-in-class cancel flows on your existing Stripe billing, Churnkey is the natural fit at $250/month with no revenue share. If you specifically want Retain's data-driven defaults and global localization and are willing to pay its standalone revenue share (reported ~10-15%) or the $500/month floor, Retain works on Stripe too, just not for free. And if your only real need is recovering failed Stripe payments, neither premium suite is necessary, a flat-fee recovery tool does that core job for far less. So for most Stripe teams the choice is Churnkey for the flat retention platform, or a focused flat-fee tool for pure recovery, with standalone Retain making sense mainly for larger global businesses.

Two capable retention tools that price and integrate in opposite ways. Retain is free inside Paddle's merchant-of-record billing (a revenue share standalone); Churnkey is a flat platform fee on any processor. The right pick is set by your billing setup, so we organized this by pricing model and processor.

The short answer

Choose Churnkey if you want flat, predictable platform pricing ($250/mo billed yearly, no revenue share) and to keep your existing processor (Stripe and others) while adding best-in-class cancel flows. Choose Paddle Retainif you bill through, or are adopting, Paddle's merchant-of-record platform (Retain is free there and deeply integrated, with strong global localization), or if you want the performance revenue-share model as a larger global business. The real fork is your billing setup and whether you prefer a flat fee or a revenue share.

The honest framing

This is a billing decision as much as a tool decision

Paddle Retain and Churnkey do similar jobs, dunning and cancellation flows, but they sit on opposite sides of two structural choices: how you pay, and where your billing lives. Comparing their features first, as most articles do, buries the decision that actually matters. Start with the pricing model and the processor, and the right tool usually becomes obvious.

Paddle Retain, the product Paddle acquired from ProfitWell, is built around Paddle's merchant-of-record billing, where it is free, and charges a revenue share when bolted onto your own billing. Churnkeyis the opposite: a flat platform subscription that layers on whatever processor you already use, with no cut of your recovery. One rewards committing to Paddle's ecosystem; the other rewards keeping your stack and paying a fixed price.

That is why this comparison is organized by pricing model and processor support rather than by feature checklist. Both address the same underlying leak, involuntary churn is 20-40% of subscription churn, so the question is not whether either recovers payments, but which pricing shape and billing fit suit you.

A note on neutrality: I make a dunning tool, so I have skin in this. The comparison below is a straight read on Retain versus Churnkey, and my own product appears once, in a clearly-marked box near the end.

The 10-second answer

On Paddle's billing? Retain is free and native. On Stripe and want a flat price? Churnkey ($250/mo, no revenue share). Want Retain's data and localization off Paddle? You pay its ~10-15% standalone share. Billing setup decides it.

The context

Revenue-share vs platform pricing: what's the difference?

This is the distinction the whole comparison turns on. One model bundles or takes a cut; the other charges a flat fee. Here is how Retain's and Churnkey's models compare on the dimensions that decide cost and fit.

Dimension	Paddle Retain (revenue-share / bundled)	Churnkey (flat platform)
How you are billed	Free inside Paddle Billing; ~10-15% of recovery standalone	Flat subscription ($250/mo billed yearly, higher tiers custom)
Cost predictability	Variable: bundled in Paddle's fee, or scales with recovery	Fixed and predictable
Cost as recovery grows	Rises (standalone percentage)	Unchanged
Processor / billing	Best inside Paddle's merchant-of-record; also works standalone	Layers on your existing processor (Stripe and others)
Do you change billing?	To get it free, move to Paddle as merchant of record	No, keep your processor
Setup	Paddle account / integration	JavaScript SDK (developer time)
Best for	Paddle-ecosystem, global, larger businesses	Teams wanting a flat price while keeping their processor

Paddle Retain

Free in Paddle Billing

· Included with Paddle's MoR billing (5% + 50c per transaction)
· Standalone: ~10-15% of recovered revenue (reported)
· Flat floor from $500/mo for smaller standalone teams
· Full detail in Paddle Retain pricing

Churnkey

$250/mo (billed yearly)

· Flat subscription; ~$300/mo billed monthly
· Starter under $5k/mo churn volume; higher tiers custom
· No percentage of recovered revenue
· Full detail in Churnkey pricing

The crossover: inside Paddle Billing, Retain is cheaper than Churnkey by definition (it is free on a platform you already pay for). On Stripe, it flips: Retain's standalone $500/mo floor is usually higher than Churnkey's flat $250/mo for a smaller team. The percentage-vs-flat trade-off is broken down in flat fee vs percentage dunning pricing.

The stack

Which fits your processor and billing setup?

The second axis, and often the deciding one. These tools relate to your billing in fundamentally different ways.

Paddle Retain: native to Paddle's MoR

Free and deeply integrated inside Paddle Billing
Paddle is your merchant of record (handles tax, fraud, payouts)
Works standalone on your own billing, at the paid revenue share
Strongest for global, multi-currency, localized selling

Churnkey: layers on any processor

Keeps your existing billing (Stripe and others)
Multi-processor; you do not change your payment stack
Added via a JavaScript SDK (developer time to integrate)
Strongest for SaaS staying on Stripe wanting flat pricing

If moving to a merchant-of-record model is on your roadmap anyway, Retain comes free with it. If you are committed to your own processor, Churnkey's layer-on model does not ask you to change how you get paid.

Read with care

What recovery rates do they claim?

Both publish recovery numbers, and both are company claims you should not treat as a head-to-head benchmark. Here is what each says, and why the comparison is shakier than it looks.

Churnkey

~64%avg (up to ~89%)

Churnkey states an average recovery rate around 64%, with a ceiling near 89% combining retries, email, and SMS (company claim, churnkey.co).

Paddle Retain

50%+("54.2%" per Churnkey)

Paddle officially describes over 50% recovery. The specific 54.2% figure often quoted for Retain comes from Churnkey's own comparison, a competitor, not from Paddle.

⚠️ Why not to trust the head-to-head: these figures are self-reported marketing metrics measured on different customer bases with different methods, and one of them (Retain's 54.2%) is a competitor's characterization. They are directional at best. Decide on pricing model, processor fit, and features, not on dueling recovery percentages. For independent numbers, see our recovery statistics report.

The verdict

Which should you choose?

Choose Paddle Retain if

You bill through Paddle as your merchant of record, or plan to. Retain is free there, deeply integrated, and strong on global, multi-currency, localized selling. It also suits a larger business that is comfortable with a performance revenue share and values Retain's data-driven defaults, even when used standalone.

Choose Churnkey if

You want a flat, predictable price ($250/mo, no revenue share) and to keep your existing processor. Churnkey layers on Stripe and others without changing your billing, and its cancel-flow builder is the most sophisticated on this comparison. The trade-off is a JavaScript SDK integration and a fixed fee that does not flex down at small scale.

It is close when

You are on Stripe and weighing standalone Retain against Churnkey. Both are premium; the decision comes down to flat fee vs revenue share and whether you value Retain's localization or Churnkey's cancel-flow depth more. At that point, ignore the recovery-rate marketing and decide on cost model and fit.

Vendor noteBudget alternative

Full disclosure, I make a third tool, and both of these are broader (and pricier) than a team that just needs failed-payment recovery on Stripe. SubRevival (subrevival.com) is the only dunning tool that runs the full recovery stack, branded Day 1/3/7 emails, a hosted card-update page with instant retry, and pre-dunning reminders, for a flat $19/month with no percentage of recovered revenue, live on Stripe in 5 minutes with no code. It does not do cancel flows (both tools here do) or Retain's localization, so it fits only when branded recovery is your need. Compare directly: vs Churnkey and the Paddle Retain alternative.

Common questions

Paddle Retain vs Churnkey FAQ

What's the difference between Paddle Retain and Churnkey?

Two big differences: pricing model and processor relationship. Paddle Retain (formerly ProfitWell Retain) is free inside Paddle Billing (its merchant-of-record platform) and charges ~10-15% of recovery, or a $500/month floor, standalone. Churnkey is a flat subscription from $250/month billed yearly that layers on your existing processor with no revenue share. Both do dunning and cancel flows. The full pricing breakdowns are in Paddle Retain pricing and Churnkey pricing.

Which is cheaper, Paddle Retain or Churnkey?

It depends entirely on your billing setup. On Paddle Billing, Retain is free (you pay Paddle's 5% + 50c fee anyway), so cheaper than Churnkey's $250/month. On Stripe standalone, Retain charges ~10-15% or a $500/month floor, usually more than Churnkey's flat $250 for a smaller team. So Retain is cheaper inside Paddle's ecosystem, pricier outside it. See the two-track detail in Paddle Retain pricing.

Do I have to use Paddle's billing to use Retain?

No, but it is where Retain is free. Paddle markets it as built into Paddle Billing (its merchant-of-record platform) at no extra cost, but it also works standalone on Stripe, where it charges ~10-15% or a $500/month floor. So you need not migrate to Paddle, but standalone you pay directly. For a Stripe business, weigh that against Churnkey's flat rate, and against a flat-fee tool, in the Paddle Retain alternatives.

Does Churnkey work with Stripe and Paddle?

Yes. Churnkey is processor-flexible, it layers on your existing billing (Stripe and others) via its JavaScript SDK rather than replacing it. That contrasts with Retain, which is native and free inside Paddle's merchant-of-record billing and charges a revenue share standalone. So committed to Stripe with a flat-priced platform: Churnkey; on Paddle's MoR: Retain. The setup cost for Churnkey is the SDK integration. See its tiers in Churnkey pricing.

What recovery rates do Churnkey and Paddle Retain claim?

Both are company claims to read with care. Churnkey states ~64% average (up to ~89% with retries + email + SMS). Paddle/ProfitWell officially describes over 50% recovery; the 54.2% often quoted for Retain actually comes from Churnkey's own comparison, not Paddle. These are self-reported, measured differently, and not directly comparable, treat them as directional. See real benchmarks in our recovery statistics report.

Which has better cancel flows?

Both are strong. Churnkey's cancel-flow builder is its signature: A/B-tested offers, pauses, downgrades, and surveys via its SDK, tuned for SaaS. Retain also offers cancellation flows with personalized offers, backed by Paddle's large dataset, inside its retention suite. For cancel-flow sophistication on your own processor, Churnkey has the edge; for a bundled suite in Paddle's ecosystem, Retain. Usually pricing and processor fit decide before the cancel-flow nuances do.

Is there a cheaper flat-fee alternative to both?

Yes, if you only need failed-payment recovery on Stripe. Both tools bundle more than a team wanting simple branded email recovery needs. SubRevival (subrevival.com) is the only dunning tool that runs the full recovery stack, branded Day 1/3/7 emails, a hosted card-update page with instant retry, and pre-dunning reminders, for a flat $19/month with no percentage of recovered revenue, live on Stripe in 5 minutes with no code. It does not do cancel flows or localization, so it fits when branded recovery is your need. Compare in SubRevival vs Churnkey.

Which should I pick if I'm on Stripe, not Paddle?

On Stripe, Retain loses its free-inside-Paddle edge, so it comes down to preference. Want a flat platform fee and top cancel flows on Stripe: Churnkey ($250/month, no revenue share). Want Retain's data and localization and will pay its standalone ~10-15% or $500 floor: Retain works on Stripe too, just not free. Only need failed-payment recovery: a flat-fee tool does it for less. See the flat-fee route in the Churnkey alternative guide.
