need help with setting and invoice

Hi I am new, 

I haven't made any bookings and income from this platform, but now they ask me to pay for an outstanding invoice. Is this the fee for using the website?

I have my listing mainly on Air BNB, and now trying to listing on here. I realized that they don't give options such as cleaning fee or the service fee. How do you set the price? 

For example, my listing on Air BNB is $85 per night for 2 guests and $150 cleaning fee, minimum 3 nights. How much would you put on there? I am just soooo confused with using Booking.com and I couldn't talk to a real person :(
