Freelance Photography - Track Profit

For those of you doing freelance photography, what programs or apps do you use to keep track of income, expenses, mileage, gear costs, and overall profit?

Do you use something like QuickBooks, Wave, Excel/Google Sheets, HoneyBook, Studio Ninja, or something else?

I’m curious what works well in real day-to-day use, especially for solo photographers or small side businesses.
