For my "small business" (remember, not really) I wrote down what was on the odometer at the beginning of day and then at the end of the day when I was done driving around door-to-door. If you're doing single trips from home (home - client - return home) then you can likely just use Google maps. If you're travelling around to multiple jobs before you get home, I'd say keep track of your odometer. Don't just track it when you fuel up because as /u/YourTaxGuy says, that can get messy with mixing in personal miles versus business miles.
