Most people shopping for a “Churnkey alternative” or a “Baremetrics Recover alternative” want the same outcome: win back the subscription revenue that fails because a card expired or a bank declined a charge. Here’s where SaveMyMRR is different, and — just as usefully — where it isn’t.
The honest one-liner: a lot of “recovery” tools mostly send emails and rely on Stripe’s own retries to do the charging, while pricing on a percentage of the MRR they recover. SaveMyMRR fires the retry itself with Stripe’s invoices.pay, on a schedule you can read, for a flat fee that never touches what it recovers.
Free plan connects Stripe and shows lost MRR. No card to start.
Every founder already has one recovery tool for free — Stripe Smart Retries — so the real question is what a paid tool adds on top. The grid below compares on capability, not marketing copy.
| Feature | SaveMyMRR | Churnkey | Baremetrics Recover | Churn Buster | Stripe Smart Retries |
|---|---|---|---|---|---|
| Fires the card retry itself | Yes — invoices.pay | Yes | Emails + Stripe’s own retries | Yes | Yes (native) |
| Retry schedule you can read | Published: 0 / 24 / 72 / 120 / 168h | ML-timed (opaque) | Stripe Smart Retries | Configurable, not published | ML-timed (opaque) |
| AI-written recovery emails | Yes — Claude Haiku, template fallback | Templated / rules | Templated | Templated | Basic Stripe email only |
| Stripe access it asks for | Restricted key only, AES-256-GCM at rest | OAuth (varies) | OAuth (varies) | OAuth (varies) | n/a (native) |
| Hosted self-serve card-update page | Not yet — on the roadmap | Yes (their core) | Yes (capture form) | Yes | Hosted invoice page |
| SMS channel | No — email only | Yes | No | Yes | No |
| Pricing model | Flat $29 / $79 per month | Monthly + % of MRR (check site) | Baremetrics add-on (check site) | Monthly / % (check site) | Free with Stripe Billing |
Competitor columns were compiled from each product’s public docs in July 2026 and kept deliberately hedged — dunning tools change fast, so confirm current pricing and features on their own sites. The SaveMyMRR column comes straight from this codebase.
A retry can’t resurrect a card that’s genuinely expired or hard-declined — at some point the customer has to type in new digits. That’s the one job SaveMyMRR doesn’t fully own yet, and it’s worth being blunt about it:
So pick on the real trade-off: if you need a customer-facing card-update wall on your domain this week, Churnkey is built for that. If you want a retry engine you can audit, on a restricted key, for a flat fee — keep reading.
Churnkey and Stripe both time retries with a machine-learning model you can’t inspect. SaveMyMRR uses a fixed cadence, printed here, so you always know what will fire and when after a payment first fails:
| When | Retry the card? | Send an email? |
|---|---|---|
| On failure (0h) | No | Yes |
| Day 1 (24h) | Yes — invoices.pay | Yes |
| Day 3 (72h) | No | Yes |
| Day 5 (120h) | Yes — invoices.pay | Yes |
| Day 7 (168h) | Stop — mark as churned | No |
Same schedule, same logic, every account. On Business you can adjust the timing. See it run on sample data on the demo, or read the full walkthrough on how it works.
Not every failed charge is recoverable, and that’s the part most recovery pages skip. Stripe hands back a decline code with every failure, and the code tells you whether a retry has any chance or whether the customer simply has to enter new digits. Here are the ones you’ll see most, from Stripe’s own decline reference:
| Decline code | What actually happened | Can a retry clear it? |
|---|---|---|
| insufficient_funds | No money in the account at that moment. | Often, later — funds land on payday. This is the highest-yield retry case. |
| do_not_honor | Generic “no” from the issuing bank, no reason given. | Sometimes — it’s frequently a temporary risk hold that a spaced-out retry clears. |
| processing_error | Something failed on the network or issuer side, not the card itself. | Usually — this is transient. A retry soon after tends to go through. |
| expired_card | The card’s expiry date has passed. | Never. The customer has to enter a new expiry or a new card. |
| lost_card / stolen_card | The bank has flagged the card (Stripe often masks these as generic). | Never. The card is dead; only a new card recovers this. |
| incorrect_cvc / incorrect_number | The stored card detail is wrong. | Never via retry — the customer must re-enter the correct details. |
The takeaway shapes the whole cadence: the soft declines at the top of that table — a payday timing miss, a jittery bank hold, a network blip — are where a retry earns its keep, and they’re the majority of involuntary churn. The hard declines at the bottom no retry engine can fix; those need the customer. So SaveMyMRR does two things at once — it retries the card at day 1 and day 5 for the soft cases, and every email in the sequence carries a link back to update the card for the hard ones.
One honest caveat: SaveMyMRR runs the same schedule whatever the code — it doesn’t branch per reason. A tool advertising “per-code ML retry timing” is optimising the same narrow window; a published cadence plus a clear update link covers most of the recoverable ground for a small Stripe SaaS.
On Pro, the copy is written per-customer by Claude Haiku and personalised to the name, brand, amount and days overdue. When there’s no AI key or the call fails, it falls back to solid static copy. This is the actual first-step template shipped in the code, verbatim:
Subject
Your payment to Acme didn’t go through
Hi Sam,
We tried to charge $29.00 for your Acme subscription, but your card was declined. It happens — usually an expired card or a temporary bank block.
You can fix it in a few seconds using the secure link below. No action means your access may be paused.
Update payment method
The sequence escalates in tone: a friendly heads-up at 0h, a firmer mid-sequence reminder, then a final notice at day 5 before it stops at day 7. On Pro the emails also send from your own brand, not from SaveMyMRR.
The point of any of these tools is whether the recovered revenue beats the fee. Put your MRR and failure rate in below — it runs in your browser, nothing leaves the page — and it’ll tell you if a $29/mo tool pays for itself or if Stripe’s free retries already cover you.
Stripe → Billing → Overview. A round number is fine.
Per customer, per month. Only used to turn dollars back into invoices.
Don't guess if you can count: failed invoices ÷ all invoices over the last 90 days.
Of the failed amount, how much comes back on its own — mostly Stripe retrying the card quietly. Your dashboard knows.
Retries plus emails plus a card-update link. Use a number you'd bet on, not a number from someone's brochure.
Every recovery tool wants to wave a big number at you — “recovers up to 89%”, “24× ROI”. SaveMyMRR is new and small, so instead of borrowing someone else’s case study, here’s the exact rule the dashboard uses to call a dollar recovered. That way the only recovery figure you ever see is your own, and you can trust how it’s built:
paid after one of our retries — the code sets the status the moment invoices.pay returns a paid invoice. No retry success, no recovered dollar.The honest caveat: some of those cards would have cleared on Stripe’s own free retry anyway, so a raw “recovered” total slightly flatters any dunning tool, ours included. The clean way to isolate the lift is to run detect-only mode first — it watches and retries nothing — then switch retries on and compare. That’s a truer read than any vendor’s headline percentage.
Want a planning number before you connect anything? The involuntary-churn calculator bounds what’s recoverable from your MRR and your failure rate — not ours.
This is the position SaveMyMRR won’t move off: you pay a flat monthly fee, and it takes none of the revenue it brings back. Percentage-of-MRR pricing quietly gets more expensive exactly as you succeed.
Full breakdown on the pricing page. Free is a real plan, not a trial — you keep the dashboard and manual recovery forever.
The biggest reason people hesitate to connect a recovery tool is handing over Stripe access. SaveMyMRR doesn’t ask for a full key or a broad OAuth grant. You create a restricted key scoped to what dunning needs — read on charges, invoices and customers, write on invoices — and paste it.

If you want the retry engine and AI emails without the percentage-of-revenue pricing or a full-account OAuth grant, SaveMyMRR is the closest fit. You paste a restricted Stripe key, a worker polls your failed invoices, and a fixed five-step sequence retries the card and sends recovery emails. Flat $29/mo, no cut of what it recovers.
It retries. Two of the five steps (at 24h and 120h) call Stripe’s invoices.pay to re-attempt the charge; the others send an email. Many email-only dunning tools only nudge the customer and lean on Stripe’s built-in Smart Retries to do the actual charging. SaveMyMRR fires the retry itself, on a schedule you can see.
Three things, honestly. There’s no hosted self-serve card-update page yet — the recovery email links customers back to update their card, but there isn’t a white-labeled page on your own domain. It’s email-only, no SMS. And it connects to Stripe only, not Paddle, Braintree or Chargebee. If you need a customer-facing card-update wall on your domain today, Churnkey is built for that.
SaveMyMRR is a flat monthly fee: $29 Pro, $79 Business. It never takes a percentage of the revenue it recovers. Percentage-of-MRR and add-on pricing can be fine at scale, but for an indie SaaS at $5–50k MRR a flat fee is usually cheaper and easier to predict. Check each competitor’s current pricing before you decide.
No. You create a restricted key in Stripe with read access to charges/invoices/customers plus write on invoices, and paste that. It’s encrypted at rest with AES-256-GCM. A restricted key can’t move money out, change your payout account or touch anything outside the scopes you grant — so the risk of trying it is low.
No, and it’s worth being straight about it. SaveMyMRR runs the same 0/24/72/120/168h cadence regardless of whether the code was insufficient_funds, do_not_honor or expired_card. The two spaced retries are tuned for the biggest recoverable bucket — temporary funds and risk holds. For hard declines like an expired or stolen card, no cadence works, so every email carries a one-tap link back to update the card. Tools that claim per-code ML timing are optimising the same short window; a published cadence plus a clear update link covers most of it for a small SaaS.
Yes. The demo runs the full five-step sequence on sample data with no key, and the involuntary-churn calculator turns your own MRR and failure rate into a yearly recoverable figure entirely in your browser. Neither sends anything or touches your Stripe account.
