I would like to know what is the most effective way to log your work travels in order to be able to claim it for tax? Is it really necessary to write down every destination I go to and who was seen, etc? Or do they need to have an odometer reading every day and night (opening and closing?) Or as some say, can it just be based on the reading from 1st March to 28 Feb?
I have downloaded an app which acts as a log book (feulio), would that be sufficient?
