Hello Bensimsjoinery, we can certainly help with the setup of mileage tracking for your vehicle in Quickbooks Online. Are you doing the setup in the browser or the app version of Quickbooks? I take it you want to use auto-tracking for your mileage rather than manually adding in trips? We have included an article that will be helpful in the setup process here
We'd be happy to go through it in more detail in the Community if you need or answer any questions you may have.
