Paperform is the tool we point to throughout this guide for turning a course idea into something people can sign up and pay for, from a simple landing page to a full enrollment and payment form. But first, the idea itself.
With the rise of elearning options, it's only natural to be curious about getting into the game. Teaching online is a great way to earn some extra cash for sharing your unique skills and passions. But, like any business, you can't just up and start an online course without an idea. With that in mind, we've put together a colossal list of 110 online course ideas to give you inspiration. They're split into industries and accompanied by a real-life success story to give you further context.
Why teach an online course
Online learning (also called 'elearning') has become a genuine alternative to in-person education, not just a fallback. A few reasons it's worth building a course rather than only offering your skills one-on-one:
Flexibility: Students work through lessons at their own pace and on their own schedule, rather than needing to show up at a fixed time.
Lower costs to run: An online course has no venue, printed materials, or travel costs. Everything is delivered through the same platform for every student, which keeps your margins better than in-person teaching.
Wider reach: You're not limited to people who can physically attend. A well-marketed course can reach students anywhere, grow your network of past students into referrals, and build recurring income as new cohorts sign up.
More ways to package your knowledge: Whether it's digital marketing, graphic design, or a hands-on skill, most subjects can be turned into a course once you've broken them into a clear curriculum.
How To Create An Online Course
Becoming an online course creator isn't as simple as putting together a presentation, recording a video, and uploading it to your website. But with some forethought, organisation, and a bit of work, you can be on your way in no time.
1. Identify your niche
The first step is to identify a subject that you specialise in, this could be anything from personal training to running a bakery. Whatever niche you settle on, the key is to be both passionate and knowledgeable about it.
Two questions to consider: what do you want to teach, and what do you know that others may want to learn? Your audience will be able to tell if you're just mailing it in, or regurgitating other people's information for your own benefit.
2. Gauge interest
It's important to make sure there's an interested audience before you get too deep into course planning. A great way to gauge interest is to make a landing page that gives an overview of your course, explains what people will learn, and lets you collect sign-ups from interested parties.
With Paperform, you can create feature-rich landing pages for any course, all in an easy to navigate editor. Include a clear call-to-action for people to sign up, register their interest, or offer 'early bird' deals for people willing to purchase early. Based on the response, you'll get a read on whether your course idea has legs, plus new additions to your email list you can use for marketing outreach.
3. Research your subject
Once you've settled on your course topic, research not only what you'll teach, but what courses are already available on the topic. Think about what people want to know, and what gaps you can fill. Now is also a good time to do some keyword research, which gives you an idea of subcategories to explore, as well as questions people commonly have.
4. Outline the course structure
Once you've collected the information on the topic, it's time to build a curriculum: a concrete plan of the lessons you'll provide and topics you'll cover. Break the broad topic into smaller sub-topics, then create individual lessons for each one with a clear outline and objective. It's a good idea to supplement each lesson with relevant resources, and to use assignments or worksheets to keep students engaged.
5. Create your course content
Once you've done your research and planning, it's time to make your course. Many teachers split content between written and video, but podcasts and live webinars work too. You don't need expensive equipment: write content in Google Docs, and use free screen recording software like Loom for video.
6. Get your course online (and start making some cash)
Time to figure out what kind of online course you want to run: a hybrid model, weekly Zoom meetings, an existing platform like Teachable or Udemy, or your own website. You could also use Paperform for the whole process: manage students, accept payments (including subscriptions), send class summaries and results, and run assessments or interactive quizzes, all from one place. Want one-on-one consultations? Connect your calendar and let students book a slot directly.

You've picked an idea. Now you need a way to take enrollments and payments.
However you landed on your course idea, the next real step isn't recording lesson one. It's building a way for people to enroll and pay you, since a course with no enrollment form is just a plan.
A course enrollment form needs to do more than collect a name and email. Most course creators need at least three things a basic contact form doesn't handle: conditional pricing (early bird versus standard, or a payment plan versus one-off), cohort or start-date selection if you're running scheduled intakes rather than always-on access, and upsells for things like a one-on-one coaching add-on.
Here's what building that in Paperform looks like:
- Start from a template. Paperform's course registration form template already has the core fields in place, so you're adjusting rather than starting blank.
- Add your pricing tiers. Use a payment field with multiple options (early bird, standard, group discount) so the price a student sees updates automatically based on what they select.
- Add cohort or date selection if relevant. If your course runs in scheduled batches rather than being always-on, add a field for students to pick their intake date.
- Set up conditional logic for upsells. For example, show a coaching-call add-on only after someone selects the premium tier, rather than cluttering the form for everyone.
- Connect payments. Paperform connects to Stripe, PayPal, Square, and Braintree, so the payment step is built into the same form, not a separate checkout page.
- Automate the confirmation. Set an automatic confirmation email with next steps, so new students know what happens after they pay without you sending it manually.
Once you're running a course business rather than a single course, it's worth looking at Paperform's education software use case for the fuller picture: scheduling classes, running assessments, and managing students, all from the same platform as your enrollment form.
FAQ
How do I know if my online course idea will sell? Build a landing page describing the course and collect email sign-ups or early interest before you build anything else. If the response is weak, it's cheaper to pivot at that stage than after you've built the full course.
What's the difference between a course landing page and an enrollment form? A landing page pitches the course and captures interest, often before it's built. An enrollment form is the transactional step: it collects payment, any required student details, and confirms someone's spot once the course is ready to sell.
Do I need different pricing tiers for my course? Not always, but early bird pricing, group discounts, or a payment plan option can meaningfully increase signups, especially for higher-priced courses. Conditional logic in your enrollment form can show the right price automatically based on what a student selects.
How do I collect payments for an online course without a separate ecommerce platform? A form builder with native payment fields, like Paperform, handles this directly. It connects to Stripe, PayPal, Square, and Braintree, so the payment step happens inside the same form as enrollment, without a separate checkout tool.
Can I run a scheduled cohort-based course instead of always-on access? Yes. Add a cohort or start-date selection field to your enrollment form so students choose which intake they're joining, rather than assuming rolling access.
What should happen right after someone pays for my course? An automatic confirmation email with clear next steps: how to access the course, when it starts, and who to contact with questions. Set this up once in your enrollment form and it fires for every new student without manual work.
Once you've picked your idea from the list above, build your enrollment form from the course registration template linked above and you'll have a way to take students' money by the end of the day.
