Flat Hourly Rate tells My School Books that this teacher will be paid the same amount per hour taught, regardless of how much the student(s) are charged for those lessons. For example, if the teacher is set to earn $30/hr, My School Books will automatically add payroll entries for lessons based on time taught (i.e. $15 for a 30 minute lesson), even if the student pays more or less than that for their lesson.
Percentage of Teacher’s Revenue tells My School Books to make the teacher’s income proportional to the amount of money charged to the student. This amount is always calculated before sales tax. For example, if the school takes a 10% cut of all lessons taught, the teacher’s pay rate would be 90% of school revenue.
