Your calendar becomes your billing source. No double entry, no second system — Psy-TimeInvoicer reads your appointments and generates professional invoices with the correct billing codes in seconds.
Psy-TimeInvoicer is the specialist module of TimeInvoicer — built specifically for psychologists, therapists and psychiatrists. All insurance billing codes are pre-installed, health data never leaves your device, and you can focus on what truly matters: your clients.
From your calendar to a finished invoice — no learning curve, no double entry, no second system.
Enter your sessions in Google or Samsung Calendar as you normally would. No new system, no new app — just keep doing what you already do.
Psy-TimeInvoicer identifies the service type, suggests matching ICD-10 diagnoses and billing codes, and fills in the invoice automatically.
Send a professional invoice via email, WhatsApp or printer. One minute — and you're back with your clients.
No feature bloat, no enterprise software for hospitals. Just what solo practitioners actually need every day.
No retyping, no double entry. Your system calendar is the data source — create an invoice with 1 click directly from the session.
All standard billing codes pre-installed and always up to date. No looking up codes, no typos.
Automatic service recognition, ICD-10 diagnosis suggestions from calendar entries and voice input — less typing, more time for clients.
Invoices with your own logo and letterhead. Send directly via email, WhatsApp or printer — looks like it came from your accountant.
Monthly overview, outstanding invoices instantly visible, automatic 3-stage payment reminders — so you don't have to chase late payers.
Insurance-ready XML export at the push of a button. Backups are end-to-end encrypted — health data stays protected.
As a practitioner, you bear special responsibility for sensitive health data (GDPR Art. 9 — special categories). Psy-TimeInvoicer was built with this protection as its foundation — not as an afterthought, not as a checkbox.
All invoices, contacts and client data remain exclusively on your device. No server, no upload, no third parties. Your clients can count on it.
You use your own local Android calendar — no external server sees your session appointments. Your data stays where it belongs: on your device.
On request, Psy-TimeInvoicer automatically creates anonymized calendars — without client names. Sync appointments across devices via Google Calendar & Co., coordinate therapy rooms or arrange coverage. Full accessibility, full privacy.
Optional backups are end-to-end encrypted. The key is generated locally on your device — even we cannot decrypt your data. Exactly as it should be.
No Google Analytics, no ad SDKs, no crash reporting with personal data. App uninstalled = all data permanently deleted.
All core features work completely offline. No server dependency — between sessions, on vacation or during network outages.
Developed in Austria, specifically for the protection of special categories of personal data. No data transfer, no cloud requirement — the highest protection standard for health data.
Web tools charge monthly fees, require constant internet and force you into their own calendars. Psy-TimeInvoicer simply uses yours.
