The challenge

A follower is not yet a customer.

Levi is a personal-finance educator building an audience on YouTube, Instagram and TikTok. But content alone isn't revenue — he needed his own platform to turn viewers into subscribers and subscribers into customers, measurably.

The twist: there is no ops team. Everything after the payment — invoice, delivery, course access, follow-up — has to happen without a human hand. One person operates the system, so the system has to do the work.

The system — 01 · Platform

Site and newsletter engine

vaslevi.hu is static, fast and fully owned: Vite + Handlebars, Coolify/Hetzner hosting, staging + prod branch deploys. Email runs on two engines: an ESP carries the funnel flows (welcome, nurture, launch), while the weekly newsletter is sent by a self-hosted Notifuse through Amazon SES — own sending domain, full SPF/DKIM/DMARC, IP warmup.

Content production is systematized: MJML templates, a format handbook, and a weekly editorial loop where no letter ships without passing a QA audit gate. Every newsletter also becomes an SEO blog post.

The system — 02 · Funnel

A quiz that tailors the offer

The 30-day course is entered through a quiz funnel: answers build a personalized plan page, and the offer adapts to it. Three tiers — Start (24,990 Ft), Fast Lane (49,990 Ft), Premium (149,990 Ft, capped at 15 seats) — with a value stack and compliant urgency.

The funnel is backed by an interactive toolkit: five in-browser calculators (compound interest, inflation, emergency fund, goal, rent-vs-buy) and an investor profile quiz — all custom-built, all measured.

What happens when someone pays?

This is the heart of the system — the part most businesses still do by hand. Six interconnected n8n workflows run here: from payment to course access there is not a single manual step.

  1. STRIPE

    A payment arrives

    The customer pays via Stripe from the plan page. The webhook arrives signature-verified — forged calls go nowhere.

    ✓ webhook signature OK — checkout.session.completed

  2. N8N — ROUTER

    Tier detection and order

    The system identifies the package tier from the payment link and records the order idempotently — a webhook delivered twice never duplicates.

    ✓ order recorded — tier: fast-lane

  3. SZÁMLÁZZ.HU

    Invoice, on its own

    An e-invoice is generated from the order automatically and lands in the customer's inbox — bookkeeping-ready.

    ✓ invoice issued

  4. AMAZON SES

    Tier-aware delivery email

    Each tier gets its own delivery letter: course access, downloads, and for Premium a coaching booking link.

    ✓ delivery email sent

  5. WHOP

    Course access approved

    A second workflow matches the course platform's join request to the paid order and approves it automatically.

    ✓ access granted — auto-approve

  6. WATCHDOG

    Reconciliation + alerting

    A check runs every fifteen minutes: any paid customer without access after 30 minutes triggers a Telegram alert. Whatever gets stuck, a retry workflow picks up.

    ✓ reconciliation done — 0 mismatches

What the machine delivers

The 30-day "money reset" course is 22 video lessons and 8 tool days, running on Whop, with the structure designed lesson by lesson. Alongside it stands a standalone product, "Your Financial Planner" — a complete Excel/Google Sheets finance system with a tutorial video, sales page and Stripe checkout.

Ten downloadable PDF guides complete the course (government bonds, tax-free accounts, an ETF x-ray and more) — generated from the same system.

If it isn't measured, it doesn't exist

PostHog EU runs across the whole system, consent-gated. Every quiz step is an event, purchases arrive as revenue events, and the weekly report is built from HogQL queries. Landing-page structure was analyzed and reordered from live data.
