Your customers aren't churning.
Their cards are.
Gatlio blocks failed subscribers at login — not the inbox. One script tag. Flat monthly rate. No percentage of your recovered revenue.
The Problem
Dunning emails don't work.
The average SaaS business loses 5–15% of MRR every month to failed payments. Not cancellations — just expired cards and bank declines.
The standard fix is a dunning email. It lands in the promotions folder. Your subscriber never sees it. You mark them churned three weeks later.
They had no idea their card failed. You lost a customer who never intended to leave.
How it works
Up and running in under 5 minutes.
No complex integrations. No changes to your payment flow. Connect, embed, recover.
Connect your Stripe account
Authorize Gatlio via Stripe Connect OAuth. No API keys to copy. No webhooks to configure. Takes two minutes.
Embed one script tag
Paste a single line into your app header. Works on any web stack — React, Next.js, plain HTML.
<script
src="https://cdn.gatlio.io/sdk.js"
data-tenant-slug="your_tenant_slug"
data-publishable-key="pk_live_xxxx"
data-api-base="https://api.gatlio.io"
></script>SPA? Call window.Gatlio.check(customerId) after auth resolves.

Revenue recovers automatically
The moment a failed subscriber logs in, Gatlio blocks their session with a full-screen billing overlay. Card updated. Access restored. You keep 100% of what's recovered.
ENFRDEESOverlay shown in the subscriber's language automatically.
Dashboard & Analytics
See every dollar. Every retry. Every recovery.
Gatlio isn't a black box. Your tenant dashboard gives you real-time visibility into subscriber payment status, retry attempts, and every dollar recovered.
Native Mobile SDKs
Your subscribers log in on mobile.
Gatlio is there too.
Dunning emails can't reach subscribers inside your iOS or Android app. Gatlio's native SDKs enforce the same billing gate at the session level — on every platform.
All four SDKs are drop-in packages. Same enforcement logic as the web snippet — subscriber logs in, card is checked, gate shown if needed. No backend changes required.

Pricing
Flat rate.
No surprises.
Competitors charge 15% of recovered revenue — forever. At $100K MRR recovering $8K/month, that's $1,200/month gone. Gatlio is $399. Flat.
✓ We never cut enforcement scripts mid-cycle if you cross an MRR cap. Upgrades happen at month-end.
How it compares
Email asks.
Gatlio enforces.
Email tools wait for your subscriber to act. Gatlio intercepts at login — no email required, no subscriber initiative needed.

How is this different from Stripe Smart Retries?
Smart Retries silently retries the charge in the background — no subscriber involvement. When the retry fails, the subscriber is none the wiser. Gatlio catches the subscriber at their next login and won't let them in until the card is updated. The two complement each other: Smart Retries handles passive retries, Gatlio handles the active recovery session.
What if my subscriber uses incognito mode or a different browser?
Enforcement is server-side. Gatlio checks subscriber status via your API on every session — there's nothing client-side to clear. Incognito, private browsing, cache-clearing — none of it bypasses the gate.
What about my mobile app users?
Gatlio ships native SDKs for React Native, Flutter, iOS (Swift), and Android (Kotlin). Same enforcement logic — subscriber opens the app, status is checked, gate shown if needed. All four are drop-in packages with no backend changes required.
Can the overlay be bypassed with browser extensions or DevTools?
No. The gate page runs inside a sandboxed iframe without allow-same-origin. Browser extensions, DevTools, and CSS overrides can't reach it. There is no dismiss button — the only exit is updating the card.
What happens the moment a subscriber updates their card?
The gate page processes the update via Stripe's Payment Element, confirms immediately, and fires a postMessage to the enforcement overlay. Access is restored without a page reload — the overlay disappears and the subscriber continues as normal.
Does it work alongside my existing dunning emails?
Yes — Gatlio is additive. Keep sending dunning emails. Gatlio catches the subscribers who ignored every one. They work in parallel, covering different surface areas.
Is Gatlio GDPR compliant?
Yes. Gatlio processes only Stripe customer IDs — no PII is stored on our servers. Your subscriber data stays in Stripe and your own systems. We're based in the EU (Berlin) and GDPR-ready from day one.

The story
"Three dunning emails sent. Zero opened. Subscriber churned. That customer never intended to leave — they just never saw the notification."
Gatlio was built by a solo developer in Berlin after watching recurring revenue quietly drain with zero visibility into why. The fix shouldn't require a finance team, a percentage cut, or hoping your subscriber checks email. It should intercept at the highest-intent moment — when they're already inside your product.
