01 How it works
An online course takes people from a problem to a result: from “I can’t knit” to a first scarf, from “Excel scares me” to a working budget. You record it once as videos, worksheets and small exercises — and sell it again and again. People don’t buy information — that’s free on YouTube. They buy a clear path, a good structure and someone they trust.
You can sell on your own course platform (you set the price and own the customer list) or on a marketplace like Udemy (they bring buyers, but take a large share and set the rules). AI helps with almost every part of the production. What it can’t do: be the person whose experience the course is built on.
- Topic
- Pre-sell
- Outline
- Record
- Sell
- Improve
With my books I learned the same thing again and again: a topic sells when it promises one clear result for one clear group. Courses work the same way. And honestly — the first version doesn’t have to be perfect, it has to help. You can always rerecord a lesson later.
02 Is this for you?
- know a topic well and have used it in practice
- can explain things step by step without losing beginners
- don’t mind being on camera or at least on the microphone
- already have a small audience — or are willing to build one
- are prepared to answer questions and update your course
- want to sell a course on a topic you only just read about
- hope that a course sells itself once it’s online
- plan to promise income or quick riches
- can’t stand selling and talking about your offer
- want to sell expensive coaching with homework checks without checking the rules
03 Where to sell — and when the law gets involved
Where you sell decides how much you keep, who owns the customer relationship — and which rules you have to follow.
04 What AI changes
AI takes over most of the production work. What used to take a team and several months now takes one person and a few focused weeks — if you know your topic.
05 Step by step — from idea to first students
All ten steps. Steps 1 to 4 make sure people want your course before you record it. Steps 5 to 10 build, launch and improve it.
Not “Everything about Excel”, but “Your household budget in Excel in one weekend”. A good course topic has a clear group, a clear result and a time frame. Look at what people ask you again and again.
Search your topic on Udemy, YouTube and in forums. Many courses and questions are a good sign — they show demand. Then ask ten people from your target group what they struggle with and what they’ve already tried.
Build a simple waiting list or sell a beta version at a reduced price with a fixed start date. If ten people sign up or pay, record the course. If nobody does, you’ve saved months — change the topic or the promise.
Write bullet points for each lesson and let AI turn them into a script — then read it aloud and change everything that doesn’t sound like you. Add one worksheet or checklist per module.
A smartphone or webcam, a decent microphone and good light are enough. Sound matters more than picture. Record short lessons, use screen recordings with OBS or Loom, and edit with a tool like Descript that lets you cut by editing the transcript.
Upload your lessons to the course platform, set prices, imprint, terms and privacy policy. For digital content, consumers in the EU have a withdrawal right, which only expires early if they expressly agree to immediate access and confirm that they lose the right (§ 356 (5) German Civil Code). And check the FernUSG point from section 3.
Send your waiting list a short series of emails: the problem, a free tip, the course opens, the last day of the launch price. Run a free live session or webinar where you teach something useful and show the course at the end. An email tool like KlickTipp, Quentn or MailerLite sends the series automatically — and Zapier connects it with your course platform, so every buyer gets tagged and receives access.
Watch where students drop out, answer questions, rerecord weak lessons. Then add: an advanced course, a live cohort, a community or a workbook. Your first course is the foundation — not the end.
06 Tools
Start with what you have. Add tools only when you need them.
07 Realistic expectations
A course is not passive income from day one. The first launch is a lot of work; after that, sales depend on how many people you reach every month. Without an audience, even a great course sells slowly. Most successful course creators first built a newsletter, a YouTube channel or a reputation in a niche.
What it can look like — a worked example
Invented example numbers. VAT comes off the gross price (Udemy handles it for its sales). Later months without a launch are usually much quieter.
08 Tips & common mistakes
- Do: Promise one clear result for one clear group.
- Do: Pre-sell a beta version before you record everything.
- Do: Keep lessons short — ten minutes at most.
- Do: Collect quotes from beta students for your sales page.
- Avoid: Recording for months before anyone has bought.
- Avoid: Making the course longer to justify a higher price.
- Avoid: Promising income or guaranteed success.
- Avoid: Adding personal homework checks without looking at the FernUSG.
09 Pros & cons
- Create once, sell many times
- Low start costs
- AI speeds up production a lot
- Builds your reputation as an expert
- Can lead to coaching, cohorts and communities
- Selling is harder than creating
- Udemy keeps up to 63 % of marketplace sales
- Courses need updates
- German distance learning law can apply
- Lots of free content competes with you
10 Risks & legal
- Distance learning law (Germany): courses where you monitor learning progress need ZFU approval — otherwise the contract is void and students can reclaim their money. Since June 2025 this also applies to business customers. Pure leisure courses only need to be reported. Have your concept checked.
- Withdrawal right: consumers in the EU can usually withdraw from digital content within 14 days — unless they expressly agree to immediate access and confirm that they lose the right. Set up your checkout accordingly.
- VAT: for e-learning sold to private customers in other EU countries, their VAT rate applies above €10,000 a year of such sales — usually via the One-Stop-Shop. Marketplaces like Udemy handle VAT for their own sales.
- Copyright: use only images, music, fonts and examples you have rights to. Pure AI output is often not protected — your own explanations, structure and recordings are.
- Promises: no income claims, no “guaranteed results”, no fake reviews or countdowns. That’s unfair competition — and the reason guru courses have a bad name.
- Data protection: your email tool and course platform process personal data. You need a privacy policy and data processing agreements with your providers.
- Registration and tax: selling courses regularly usually means registering with the tax office. Ask whether it counts as freelance teaching or a trade.
General information only, not legal or tax advice. Rules differ by country and change — check the official pages (e.g. ZFU, Federal Central Tax Office) and ask a lawyer or tax adviser before you sell coaching or courses with personal support.
11 FAQ
Do I need to be an expert?
You need to be clearly ahead of your students and have used the topic in practice. Many good courses are made by people who solved a problem themselves two years ago and remember what was hard.
Own platform or Udemy?
Udemy brings buyers but keeps 63 % of the sales it brings in and largely controls prices. On your own platform you keep almost everything and own the email list — but you have to bring the buyers yourself. Many start with a beta on their own platform.
Does my course need ZFU approval?
In Germany, if it’s paid, mostly remote and you or an assistant monitor learning progress — for example by checking homework. A self-paced video course without personal learning checks is usually not affected. If in doubt, ask the ZFU or a lawyer.
How long should a course be?
As short as possible, as long as necessary for the result. Many good beginner courses have two to four hours of video, divided into short lessons.
What should it cost?
That depends on the result and the target group. Hobby courses often cost €29–99, professional courses with a clear benefit €99–499. Test with a beta price and raise it as you get reviews.
Can AI make the whole course?
It can write a generic course on any topic — that’s exactly why nobody pays for one. Use AI for structure, scripts and materials, and fill it with your experience.
Do I need to show my face?
No, screen recordings and voice-over work well for many topics. Showing your face builds trust faster, though.
Do I have to register a business?
Usually yes, once you sell regularly. Ask your tax office whether it counts as freelance teaching or a trade.
