The easiest mileage log in Austria.
A small plug in your car, or the app on your phone, records every trip. You tap once: business or private. Your accountant gets the rest ready-made.
Light, phone only, is free. Premium, with the plug, is €10 a month. Both free to try for 14 days. Your data stays in Europe and is kept for seven years, exactly as the Austrian tax office requires.
