ProfitWell Retain has been a fixture in the SaaS dunning conversation for years. The pitch is hard to argue with on the surface: "You don't pay unless we recover revenue." Set it up, let it run, only get billed when it works. If it worked that cleanly for everyone, no one would buy anything else.
The reality is more nuanced. Retain uses a percentage-of-recovered-revenue model, and that math cuts differently depending on your MRR, your recovery rate, and how hands-on you want to be. Here's how the pricing works, what changed after Paddle acquired ProfitWell in 2022, and when a flat-fee alternative saves you real money.
Quick history
ProfitWell launched Retain as part of its free SaaS metrics platform. The product was always monetized through a percentage cut of the failed payments it recovered. Paddle acquired ProfitWell in 2022 and has since rolled the tool into the Paddle ecosystem as Paddle Retain. The underlying pricing model is the same. If you see "ProfitWell Retain" in docs or old blog posts, it's the same product, now Paddle-branded.
Paddle itself is a merchant of record (MoR), which is a different animal than Stripe. More on that in a minute.
How the pricing actually works
Retain charges a percentage of the revenue it successfully recovers from failed payments. Historically that percentage has sat in the 20% to 35% range depending on deal size, volume, and what else you're buying from ProfitWell/Paddle. It's custom-quoted, so your number depends on what you negotiate.
The pitch:
- No monthly fee
- No setup cost
- Only pay on success
The tradeoff:
- You hand over a meaningful chunk of every recovered dollar, forever
- The vendor's incentive is maximum recovery, which is fine until their sequences feel too aggressive for your brand
- You can't easily predict next quarter's cost
The math on a real SaaS
Let's take a B2B SaaS at $250K MRR. Roughly 9% of MRR hits Stripe as failed payments in a normal month, so about $22,500 in monthly failures. A good multi-channel dunning flow recovers 60% to 80%. Pick 70%, which is $15,750 recovered.
Now apply each pricing model.
| Model | Monthly cost | Annual cost | Effective % of MRR |
|---|---|---|---|
| Retain at 25% of recovered | $3,937 | $47,250 | 1.6% of MRR |
| Retain at 30% of recovered | $4,725 | $56,700 | 1.9% of MRR |
| Rekko Essential (flat) | $49 | $588 | 0.02% of MRR |
| Rekko Pro (flat, with SMS) | ~$200 | $2,400 | 0.08% of MRR |
At $250K MRR, the difference over a year is between $45,000 and $55,000. That's not a rounding error. That's a meaningful budget line.
And here's the kicker. Retain's recovery rate is not dramatically different from Rekko's or any other tuned dunning tool. The underlying playbook is well-understood: real-time webhook, intelligent retry cadence, email sequences, ideally SMS. Recovery rate comes down to execution, not secret sauce.
Who Retain actually fits
Revenue share makes sense in specific situations. It's not a scam, it's just a model with tradeoffs.
You're on Paddle already. If Paddle is your merchant of record for billing, Retain is tightly integrated and in some plans is bundled with your Paddle fees. The friction of adding a separate tool might not be worth the savings.
You want zero setup and zero negotiation. Some teams genuinely don't want a fixed line item on the P&L. Revenue share shows up as contra-revenue and never triggers a budget conversation. If that matters to your finance culture, Retain wins.
You're at very small scale. At $15K MRR recovering $1,000 a month, a 25% cut is $250 and a flat $49 fee is $49. Flat fee still wins, but the absolute difference is small enough that the convenience of "no setup, no bill until it works" has real value.
You're running the ProfitWell metrics stack anyway. If Retain is bundled with other tools you already use and trust, the consolidation has value.
Who Retain does not fit
Most scaling SaaS teams outgrow the model fast.
Anything above ~$50K MRR. The percentage cut starts producing annual bills in the mid five figures. That's enterprise-tier dunning pricing for a tool that does not do enterprise-tier things.
Anyone on Stripe directly. Paddle Retain works best inside the Paddle ecosystem. If you're on Stripe, you're forcing an integration that wasn't the product's center of gravity. Dedicated Stripe-first tools like Rekko, Stunning, and Churnkey are built around Stripe webhooks, Stripe customer portal, and Stripe invoice objects.
Teams that want to tune aggressively. If you improve your recovery rate by 10 percentage points through better copy, timing, and SMS, Retain captures 25% of that upside. Your optimization work pays the vendor, not just you. Flat-fee tools let you keep 100% of whatever improvements you squeeze out.
Finance teams that want predictable costs. "20% of a number we can't forecast" is hard to budget. $49 a month is not.
The merchant-of-record wrinkle
Paddle Retain is now part of a broader Paddle offering, and Paddle is a merchant of record. That means Paddle takes responsibility for sales tax, VAT, compliance, and chargebacks in exchange for roughly 5% plus 50 cents per transaction on your total revenue, not just recovered revenue.
If you're considering Paddle as your primary billing platform, Retain comes bundled and the "pricing" conversation is really a "do I want an MoR" conversation. That's a much bigger decision than choosing a dunning tool, and it has implications for your entire finance stack.
If you're staying on Stripe and just want failed payment recovery, Paddle Retain as a standalone product has gotten harder to buy post-acquisition. Paddle has been steering customers toward the full platform rather than selling Retain as a bolt-on.
The "no risk" framing, examined
Retain's core marketing argument is that you take no risk. No upfront fee, no commitment, you only pay when we recover. This is true in a narrow sense and misleading in a broader one.
You're not taking cash risk upfront, sure. But you are taking several other risks that don't always get named.
Brand risk. Retain sends messages on your behalf. The tone, timing, and aggressiveness are tuned to maximize recovery, which is aligned with your vendor's revenue but not always with your customer relationship. If the sequence is too pushy for your brand, you can customize it, but you're fighting the default optimization.
Opportunity cost risk. Every month you run a 25% revenue share instead of a $49 flat fee is a month of margin you're leaving on the table. At $100K MRR recovering $6K/month, that's $1,450 of foregone savings monthly, or $17,400 a year. Not catastrophic, but it's real money going to a vendor for work a cheaper vendor does just as well.
Data portability risk. When you decide to leave Retain, you lose the sequences, the templates, and the historical recovery data inside their system. You can export the basics, but the tuning knowledge often walks out the door with the account.
Incentive alignment risk. Revenue share aligns the vendor with "recover as much as possible," not "recover as much as possible while respecting the customer relationship." Most of the time these are the same thing. Occasionally they're not, and the vendor's UI defaults reflect their incentives.
None of these are unique to Retain. They show up in any revenue-share pricing model. The point is just that "no risk" is marketing language, not an accurate description of the tradeoffs.
Flat-fee alternatives worth comparing
If the revenue-share model doesn't fit, these are the main flat-fee options.
| Tool | Pricing | SMS | Stripe native |
|---|---|---|---|
| Rekko | $29 to $129/mo flat | Yes (pay-per-use) | Yes |
| Stunning | $50 to $200/mo flat | No | Yes |
| Slicker | $49+/mo flat | No | Yes |
| Baremetrics Recover | ~$50 to $200/mo add-on | No | Yes |
Among these, Rekko is the only one that includes SMS natively at SMB pricing. SMS matters because adding it to a recovery sequence lifts recovery rates 30% to 40% over email-only. For a deeper comparison see our Paddle Retain alternative page.
Our honest take
ProfitWell Retain was a great product for the era it launched in. The "only pay on success" pitch solved a real problem for early-stage teams that didn't want to commit to a monthly bill before proving value. That era is basically over. Dunning is now a commoditized capability, the playbook is public, and the math on revenue share stops making sense as soon as you're recovering more than a few thousand dollars a month.
If you're on Paddle as your billing platform, Retain is fine. If you're on Stripe and want predictable costs, a flat-fee Stripe-native tool will save you real money.
