Summary

Harness is a web-based calendar and studio management platform for private lesson instructors. Students can use shared scheduling or rescheduling links to select available times, and families can view lessons, notes, and invoices in a student portal. Instructors can set rates, billing schedules, and payers. Calendar tools include attendance and payment tracking, lesson events with assigned rates, drag-and-drop scheduling, and availability annotations. Student profiles bring together contact details, lesson history, and payment balance, with automatic status tracking and intake forms. Finance features include income and expense tracking, invoices, Stripe-powered payments, profit and loss statements, and Schedule C compliant exports. The free Hobby plan is 0.00 USD per free and supports up to 5 students. Professional costs 15.00 USD per month and lists unlimited students, automated monthly billing, payment reminders, self-serve scheduling links, and priority email support. Harness offers a 30-day trial and is in active development. Its documentation says instructor data is isolated at the database level.
