@Julie3775 That makes sense. Try this:
Go to Account -> Payments & payouts -> Payouts
Scroll down to Payout methods and add your friend's bank account
It will probably need to be approved and that might take a day or two
When it's set up, scroll down to Payout Routing Rules -> Add payout routing rule
Choose the listing, and then choose the bank account where the money is to be sent.
This should work, unless they don't accept a bank account that is not in your - the host's - name as the primary payout method. If that is a requirement (I just can't remember - sorry!), you could add both your accounts and split the payouts (95%/5%, for instance). But if they accept her bank account you can have 100% of the payouts sent to her.
