@Larissa4 I'm not sure if this is what you're looking for, but I simply use a spreadsheet with the following columns:
Date / Guest / Payout / Cleaner / Supplies / Mortgage
Payout = how much Airbnb sends you (+)
Cleaner = cost of your professional cleaner (-)
Supplies = things like sheets, towels, cleaning products, toilet paper, books, etc (-) ** You can add another column next to this to use for notes to specify what the item was.
Mortgage = or rent (-)
This is not advice for tax purposes. You would have to check to see what your local tax rules say about allowable deductions.
This is simply so I can keep track of money going in/out. I update it maybe twice a month, downloading data from Airbnb and checking my credit-card statements.
Hope it helps.
