Calendar-First

Your Calendar. Your Invoice.
No Double Entry.

  • No double entry. Appointments already exist in your calendar — TimeInvoicer turns them into invoices.
  • No vendor lock-in. Your data stays in your system calendar and contacts. Switch anytime you want.
  • No new system to learn. Already using Google Calendar, Samsung Calendar or Outlook? Perfect. That's all you need.
  • Works offline. No internet connection required. Your practice runs even without WiFi.

Every feature solves a real problem. No bloat, no overhead.

Quick Invoice

10 seconds. One invoice. Tap an appointment or use voice input — client, service and rate are prepared automatically.
