if you were curious how you sell coaching inside of skool it's pretty simple: make a custom offer for them in the classroom then send over an agreement that they e-sign - contigent on the skool paywall
define the terms; length; payment amount; refundable or nonrefundable; cancelation or termination clauses (you can honestly ask ai to just generate a coaching contract for you then free e - sign it)
once payment is collected; the process begins! then you can delete the custom offer - the signed agreement is what is the most legally enforceable
