A course funnel is the ordered path a buyer walks from the thing that first caught their attention to the receipt for your course, and every step on that path sits on a platform you are paying for. The path is short. Something free earns the email address, a short sequence makes the case, a page asks for the card, a checkout offers one more thing, and the course itself is delivered behind the login. Drawing the path before you build it is a money decision rather than a design one, because each platform in the chain charges either a flat monthly price, a share of every sale, or both, and a funnel stitched from four tools you pay for separately can quietly cost more than the single platform that would have hosted all of it. Read the course funnel guide on this site for the shape, then put your own launch numbers into the free platform fee calculator on this site to see what each option leaves in your account.
What is an ecourse, and what the funnel is selling
What is an ecourse in this context: a set of lessons, usually video with worksheets, that a buyer pays for once or subscribes to, delivered on a platform that handles the login, the checkout and the payout. The funnel is not selling the lessons, it is selling the outcome the lessons produce, and that distinction decides every word on the page that asks for the card. It also decides where the course lives, because a one time purchase and a recurring membership are billed differently and not every platform does both well.
The course sales page
The course sales page is the only page in the funnel whose whole job is the transaction. It states who the course is for, what the buyer will be able to do afterwards, what is inside, what it costs and what happens if it does not work for them. Everything else on the page is in the way. Most course platforms ship a page builder for exactly this, and if yours does, use it rather than paying a separate builder, because a page hosted on the same platform as the checkout removes a redirect and a second subscription from the funnel.
Order bumps and what they do to the cart
Order bumps are the small extra offered inside the checkout itself, a single checkbox next to the card fields: templates, a workbook, a recorded walkthrough, priced well below the course. They work because the buyer has already decided and the friction of one more decision is a tick rather than a second checkout. Whether you can run them at all is a platform question, not a copy question, so check the checkout before you plan around them. Platforms differ sharply here: some build bumps into the cart, some expect you to bolt on a separate funnel tool to get them.
A worked launch, with the cut taken out
Put numbers on it. A course at 200 dollars sold to 40 buyers in a launch week is 8,000 dollars. An order bump at 47 dollars taken by 12 of those 40 buyers adds 564 dollars, so the cart collected 8,564 dollars across 40 transactions. Now take the platform out. Teachable's Starter plan carries a 7.5% transaction fee on sales, removed on the tier above, which on 8,564 dollars is 642.30 dollars. Card processing on a creator platform is the processor's standard fee, 2.9% + $0.30, which across those 40 transactions is 248.36 dollars plus 12 dollars, so 260.36 dollars. You keep 7,661.34 dollars. The bump paid for itself and then some, and the fee tier above is worth buying the moment its monthly price falls below what the sales fee costs you.
Cohort based courses run a different funnel
Cohort based courses sell a start date, not a library, so the funnel has a deadline in it and the cart closes. That changes the platform requirement rather than the arithmetic: you need scheduled enrollment, a way to close and reopen the checkout, and somewhere for the group to talk while the cohort runs, which is why creators selling cohorts often end up on a platform that carries a community alongside the lessons. Run the same fee arithmetic on the cohort you actually expect to fill, not the one you hope for, before you commit to a monthly plan.
Questions people ask about course funnel
Do I need a separate funnel tool to sell a course?
Usually not. If your course platform hosts the sales page, the checkout and the delivery, a second funnel subscription adds a monthly cost and a redirect without adding a sale.
What should an order bump cost?
Low enough that the buyer does not reconsider the main purchase, and directly useful for the course they just bought. A small fraction of the course price is the usual shape.
Is a sales page enough on its own?
It can be if traffic already arrives warm. Cold traffic almost always needs something free first that collects the email address, because the sale happens over days rather than in one visit.
How do I compare two platforms for the same funnel?
Price the funnel, not the plan. Add the monthly cost to the sales fee at your expected volume, and compare that total against the same launch run on the other platform.
