Extended stays.

I have a guest that extended his stay and need to know how to go about sending the money he paid to airbnb for their share.

@Nancy489: So your guest paid you outside of Airbnb and you want to know how to pay Airbnb?? If this is the case you went about it incorrectly. If a guest ever wants to extend a stay you need to send them a revised itinerary and have the guest confirm via Airbnb. Having a guest book outside of the Airbnb platform after/during a booking opens you up to all kinds of negative possibilities.

As far as paying Airbnb in the scenario you speak of. There is no way.

It a very kind answer.  You should have thanked the host for her honesty and not been so curt.
