I have just finished updating one of the studio business forms from the Printables page for the 2015-16 school year. It is called the Record of Lesson Attendance & Payment pdf. I do not currently use this form myself anymore, but I have received quite a few requests from teachers who used it last year so I was happy to update it again this year!
In case you haven’t seen this, here is how the form works: Write your students’ names in the first column. Each week, write the lesson date (in a month / date format) in the column for that week. This is how you can track attendance. The small circles in each cell are where you can write checkmarks indicating tuition payments. Whether you charge by-the-week or by-the-month, you can place a checkmark by each paid lesson date.
Download it here or on the Printables > Studio Business page.
P.S.: Here is a link to where I explain my current system for tracking payments received.
