Easy to set up for new vehicles as it can import data straight from vehicle computer systems into an easy Excel spreadsheet format that you then just update when things change such as mileage etc.- No problems so far other than not having more advanced features out of box - but if they were there we would have used them! We are able track our fuel usage using miles driven in each day which allows us see how much profit or loss was generated by particular journeys/days compared against expected performance at various times throughout year (which also helps keep budgets).
