The base Booking.com commission in Poland is usually 15%, but visibility programmes (Preferred Partner, Genius, last-minute deals) push it to 18 to 25%. Airbnb usually takes 15 to 20% from the host (the host-only model) or splits the fee with the guest.
What is the commission calculated on?
On the total gross value of the booking, including the cleaning fee and extras. You pay it on EVERY booking, including one from a guest returning to you again.
How do I stop paying commission?
Without giving up the portals: you add your own commission-free reservation page and send returning guests and referrals to it. The calendars sync over iCal, so there are no double bookings.
Does your own page really pay off?
On a fixed subscription from PLN 27.99 net a month, one or two direct bookings a month are enough to cover the cost. Everything above that is margin you have won back.
Keep that money yourself
