A Bern chauffeur service is private transport booked in advance at a fixed price in Swiss francs, carried out by a Swiss-registered licensed chauffeur operator working under the Canton of Bern's trade act (HGG) and taxi ordinance (TaxiV) and the municipal rules of the City of Bern, with every driver holding the federal code 121 permit for professional passenger transport. It is not hailed and it does not wait at a taxi stand. The car, the driver and the price are agreed before the day, whether that is a Zurich Airport to Bern transfer, an hourly car service in Bern or a black car to the Bundeshaus.
What it saves you is uncertainty. A metered fare from Zurich Airport to the capital keeps running through every slow kilometre around the Wankdorf interchange, and an app price can move with demand when parliament sits or the Zibelemärit fills the old town. A booked Bern car service does neither. The figure agreed at booking already contains the 8.1 percent Swiss VAT, the motorway vignette, any airport forecourt or parking charge for your pickup and, on the Zermatt run, the Lötschberg car-train fare.
The same reservation reaches well beyond the city. Bern Airport transfers from Belp, Geneva Airport to Bern for flights from the west, a Bern Expo transfer to the halls at Wankdorf, and long runs to Interlaken, Gstaad, Lausanne and Zurich. Federal offices, associations and companies moving people through the capital every month can add corporate travel in Bern for central billing and traveller reporting on the same fleet.
