Notion Template: Build a Digital Product
From the experience of building the Permaculture Garden Planner — the template that takes you from app idea to sold digital product.
Who is this for?
You have an idea for a digital product — a web app, a tool, a service — and you're asking yourself:
- How do I validate the idea before I invest months?
- Which architecture decisions should I make without painting myself into a corner later?
- How do I organize the build between day job, family and sleep?
- How do I monetize (one-time purchase, subscription, freemium) — and which platform?
- What is GDPR-compliant and how do I solve it without a lawyer?
- How do I launch when I have no marketing budget?
The template is the answer, because I went through these questions for the Garden Planner — idea → live → first sales. Every decision, mistake and what actually worked is in there.
What's inside
- Idea validation framework: a one-week check on whether your idea has a market (market research, target group, competition, price anchor)
- Architecture decision trees: frontend, backend, database, hosting, payment — with concrete recommendations depending on the type of idea
- Sprint planning: how to get from idea to MVP in about 3 months, without burnout
- Marketing playbook: press kit, boilerplate, affiliate setup, launch sequence
- Legal templates: imprint, privacy policy, terms as a starting point (no substitute for a lawyer, but 80 % of the way there)
- Payment integration: comparison of payment providers for the DACH region (Stripe vs LemonSqueezy vs Digistore24) + webhook patterns
- Cost model: hosting, APIs, taxes worked through realistically
- Garden Planner postmortem: what went wrong during the build and why
The template is in its final build phase.
Right now: free for early testers in exchange for honest feedback — direct contact by email. You get early access, I get pointers on where it still snags.

With the Garden Planner the biggest problem wasn't the tech — it was all the decisions outside the tech: which climate-data API? Payment provider for the DACH region? How much plan content free, what's premium? How do I structure affiliates? What do I put in the imprint? When do I start marketing?
All of that now lands structured in the template, so you don't need the same weeks I burned through.
