The Fleet Biluppgifter module is an add-on to the Fleet module that makes it easy to fill in vehicle information. By entering the vehicles registration number, the module searches for and retrieves all available information about the vehicle from biluppgifter.se, a Swedish website. This information is then automatically populated into the relevant fields, making it quick and easy to update vehicle information. With the Fleet Biluppgifter module, you can ensure that all vehicle data is accurate and up-to-date, saving you time and improving the efficiency of your fleet management.
