Stop giving up 9% of your MRR to third-party platforms because you can't set up a Webhook.
Your Astro landing page flies, but your checkout redirects to LemonSqueezy or Gumroad, killing conversions and inflating your costs. I install a native Stripe payment flow with Serverless architecture directly in your repository. Zero servers. Zero middlemen. Zero friction.
Don't trust performance promises. Audit the latency yourself.
Pay €1.00 below. If the gateway takes more than 400ms to open, or the receipt takes more than 2 seconds to hit your inbox, close this tab.

| Backend Infrastructure Cost | Not applicable | €0 / month (Vercel Edge / Cloudflare) |
| External Redirects | Yes (Conversion drop) | None (Checkout under your domain) |
| Customer Data Ownership | Held by platform | 100% Yours (Direct to your CRM/DB) |
Why it works
Cryptographic Security
The Webhook validates Stripe signatures at the Edge. Impossible to inject fake payments from the frontend.
Astro Speed Intact
Pure HTML on the client. Zero blocking JavaScript until the user clicks. Your PageSpeed stays at 100.
Zero Obsolescence
We use the official Stripe API pinned to version 2026-01-28.clover. Immune to database-breaking updates.
Delivery Guarantee & Zero Risk
Functional code will be delivered via a direct Pull Request to your main repository strictly within 48 hours of receiving full technical credentials. If the Webhook doesn't return a 200 OK after Staging deployment, an immediate and unconditional refund of your deposit will be issued. I take on the execution risk.
One-time implementation fee: €495
You recover the investment upon billing your next €6,000. Simple math.
