I put together a free worksheet to help me keep track of my mileage with work. Feel free to save a copy to your own google account. I find a web based tracking system is easier for me than writing in a book. I can access it from multiple computers, and it doesn’t matter what operating system I’m using. Make sure you write down what the mileage is for. If you have two trips during one day, just add a row, put in the same date and enter the new mileage. I was using my accounting software to track it, but they are closing up shop and I need a new software to use. This mileage tracker is actually easier than my old system. Let me know if it works with smart phones.
