If you work as a therapist, coach or psychologist, you know that bookings are only a small part of the job. Most booking tools are built for salons, wellness centres or massage therapists. Lumi is a booking system for therapists, made specifically for mental health work, with the emphasis on security, flexibility and simplicity. Unlike other systems, it brings everything you need under one roof: bookings, payments, invoices and session notes.

7 reasons therapists choose Lumi

- You decide when clients pay. For each service, choose whether the client pays before the session or after it. Lumi emails them the invoice automatically.
- Notes that are secure, structured and tied to each session. Not just “a note on the client”, but a proper record of every session, built around privacy and data security.
- Settings for each client. Every client can have their own discount, invoicing settings and preferences. No more working around the system or making exceptions by hand.
- No features you don’t need. No use for stock, a till or discount campaigns? Lumi focuses only on what you actually need as a mental health professional.
- Respect for your relationship with clients. The emails your clients get are matter-of-fact, with no marketing speak, and Lumi never contacts your clients without your consent.
- No commitment. Lumi is paid monthly, and it’s free for up to 10 sessions a month. Want to stop? Just cancel — no penalties, no stress — and export your session overview and invoices to CSV or PDF yourself first.
