I watched the entire master class, loved it! You don't mention tracking mileage (for sourcing or to post office for packages) in an expenses SOP? How do you track and record your mileage Beau? Do you use a tracking app or write it manually in a notebook on your dashboard? I know it's needed for tax deductions. I tried using MileIQ but it was too much work to mark every drive as personal or business. Any tips?
