To sell a course from your own website, you need three things: a sales page that pitches it, a payment step (cards and PromptPay via Stripe), and a way to deliver the lessons to buyers after they pay. Selling direct means you keep the full price instead of a marketplace's cut, you own your students' details for future launches, and you control your brand and your pricing. Course marketplaces are easy to start on, but they take a large slice and keep your students at arm's length. Your own site flips that relationship in your favour.
Why sell a course from my own site instead of a marketplace?
Three reasons that add up fast. First, price: marketplaces can take 30–50% of every sale, so selling direct can nearly double what you keep from the same course. Second, ownership: on your own site you get the student's contact details, which means your next course or cohort launches to an audience you already own, for free — on a marketplace, those students belong to the platform. Third, control: you set your own price, your own brand, and your own positioning, instead of being one more tile in a crowded catalogue where everything is discounted to the floor. The marketplace optimises for the marketplace; your site optimises for you.
What do I actually need to sell a course?
Three parts, and no more to start. A sales page that clearly explains what students will learn, who it's for, and why it's worth the price — with outcomes, a curriculum outline, and proof like testimonials. A payment step that takes cards and PromptPay so Thai buyers can pay the way they expect. And delivery — a simple, reliable way for buyers to access the lessons once they've paid, whether that's videos, documents, or a mix. Put those together and you have a complete course business, not a collection of disconnected tools.
How do I actually get people to buy?
Traffic plus a convincing page. Drive interested people from your email list, your social channels, and your content, and let the sales page do the persuading with clear outcomes, a curriculum they can picture themselves completing, and real testimonials that prove it works. The advantage of selling to your own audience is conversion: people who already follow you or have bought from you convert far better than cold marketplace browsers comparing ten similar courses on price. A warm audience and a clear page beat marketplace "reach" for almost everyone.
Do I need separate course software?
Not necessarily — and stitching together a page builder, a payment tool, and a separate course platform is exactly the kind of fragmented setup that costs more and leaks students. If your website builder includes course selling, payment, and lesson delivery in one place, it's all connected and attached to the same CRM as the rest of your business, so a course buyer is also a contact you can market to later. One integrated system beats three tools that don't talk, for the same reason it does everywhere else: fewer gaps, less admin, nothing lost between apps.
How should I price and package it?
Price on the outcome, not the hours of video. A course that helps someone get a job, run better ads, or pass an exam is worth far more than "six hours of content," and pricing it too low can actually signal low value. Package it so the transformation is obvious on the sales page — modules that map to steps toward the result — and consider tiers (course alone, or course plus documents/support) so different buyers can choose their level. Because you keep the full price, you have room to price fairly and still earn well.
How do I turn one course into a business?
Own the students and keep serving them. Because their details are yours, every future course, workshop or membership launches to a warm list that already trusts you — which is how a single course becomes a recurring income stream rather than a one-off. Deliver real results, stay in touch, and your first cohort becomes the marketing for your second.
How do I stop people sharing the course for free?
You reduce the risk with sensible gating, and you win with value rather than locks. Deliver lessons behind a login or a paid access step so the material isn't sitting on a public URL anyone can pass around, and use document controls — view-only where it makes sense — for downloadable resources. But accept that no system is perfectly leak-proof, and that most of your protection comes from what casual sharing can't copy: your ongoing updates, your community or support, and the trust of buying from you directly. Price and package around the whole experience, not just the video files, and honest buyers will happily pay — while your energy goes into serving students rather than policing them.
Krubly lets you create and sell a course directly from your site — a branded sales page, card and PromptPay checkout via Stripe, and lesson delivery including documents — all attached to the same CRM as the rest of your business. You keep the full price and the student relationship, and you launch your next course to an audience you own.
