If you want to monetize Academy’s courses on Schoox's Marketplace you can give special authorization to certain members to be able to set a price for a course. You can do this through the Manage Members menu (Admin -> Manager Members).
All paid courses have their own Financial Dashboard where the instructor can track revenue from different types of sales (organic sales, discount sales, coupon sales). Admins of the Academy also have access to the Financial Dashboard of the Academy where they can track sales for all paid courses of their Academy.
Note: Instructors have the ability to create courses in your Academy. Professional Instructor can create courses and offer them for a price, in your Academy.
