You can now download your earnings for a specific period of time direct from your Tutorful account on the web.
To do so, log into your account and select the 'Earnings' tab at the top:
From here, you can use the box on the right to filter by date and the download button to create a CSV of your earnings for a period of time.
You can also see your total earnings here and earnings over an entered period of time.
You can also see your earnings per lesson on your dashboard, in lesson details and when you book a lesson. Read more about this here.
