Should I deliver my product as a course or as a file?
Updated
The short answer
Deliver as a file when the buyer wants the answer now, and as a course when the order of the lessons matters and people need walking through it. A file is finished the moment you upload it. A course is a place you host, update and answer questions in.
For a first product, a file is almost always the right call.
A file is done when you upload it
One upload, automatic delivery, almost no ongoing work. The buyer keeps it forever and you have nothing to maintain.
That is the whole appeal, and it is a big one.
A course is a place you host
Lessons in order, progress tracking, and a login the buyer returns to. You can update it any time and everybody sees the change.
It is also a commitment: questions to answer, videos to re-record, a platform to keep paying for.
You can do both
Many sellers host the course and sell the templates and worksheets from it as downloads.
The downloads are often the easier sale, and they lead people into the course.
