Startup Idea: Guitar Lessons Payment and Scheduling Software

Startup idea to develop software that assists guitar teachers in scheduling lessons, tracking payments, and managing makeup lessons effectively to avoid potential loss of money and improve organization.

I teach guitar lessons from my home studio. The biggest problems I have is keeping track of payments and scheduling. Currently I am using an excel spreadsheet to do this but it relies on me remembering who showed up and who paid.

Students are allowed to do makeup lessons if they give me advanced notice. This gets really confusing since some students have 5 or 6 makeup lessons on file. I have a really hard time keeping track of these and sometimes when I look back I feel like I am losing money.
