I teach group exercise classes at several gyms every week. Each one pays a different rate, wants its invoice in a different way and has its own cover arrangements. Keeping track of what I had taught where, who had covered for me and what each gym still owed me took far too long. So I built my own trackers in Google Sheets. Instructor Hub is where I share them with other freelance instructors. Every tool here is one I use myself: simple, practical and built for the way instructors actually work. Questions or ideas for a tool you need? Message me any time.
