Harness
What it is
Harness is a web-based calendar and studio management platform for private lesson instructors. Students choose available times through shared scheduling or rescheduling links, while families view lessons, notes, and invoices in a student portal. Instructors can set rates, billing schedules, and payers. Calendar tools track attendance and payments, assign rates to lesson events, support drag-and-drop scheduling, and record availability. Student profiles combine details, lesson history, payment balance, automatic status tracking, and intake forms. Financial tools include income and expense tracking, invoices, Stripe payments, profit and loss statements, and Schedule C compliant exports. The free Hobby plan costs nothing and supports up to five students. Professional costs $15 a month, billed at $15/month, with 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.
