Sessionz is FREE to download and use and there are no membership fees for host accounts.
Hosts are only charged a small commission fee on every confirmed booking. The commission is automatically deducted in your payouts. If you cancel a confirmed booking, you won't make any earnings from this cancelled booking so there is nothing there to deduct.
If you have any questions, ideas on how we make your experience better, or simply just to connect with us, contact us at firstname.lastname@example.org. We're happy to listen and help!
