Hi @Glo0,
I do apologize for the delayed response. Regarding special offer, you will have to compute ur nightly rate multiply to how many days minus your discount plus the cleaning fee plus the extra guest fee. For example:
$100*30 nights= $3000
For example the discount you are going to give is 10%
So it will be $3000-$300= $2700
$250 cleaning fee
$10/extra guest per night(for example there are 5 guest and u are charging extra guest after the first guest)
$10*4=$40
$40*30nights= $1200(extra gues fee)
So...
$2700+$250+$1200=$4150
$4150 should be the amount that should put as subtotal. Please remember that airbnb will still add there service fee to that.
I hope that helps.
