Quick verdictAn online course is a scalable way to package your expertise — and platforms like Systeme.io make selling and delivering one straightforward.

The basics

Online courses typically include video lessons, text, quizzes or assignments, and a community. Students get access through a course platform after purchasing or enrolling.

How they're sold

Getting started

Package one topic you know well into a handful of lessons, price it simply, and use a platform with built-in checkout to start selling.
