Now that you have completed general pricing setup per the above article, this article goes into details how the Security Deposit field works across the channels.
It does flow to all channels, but while Vrbo, Booking.com and Hostfully Direct (where PMs handle payment themselves) have it displayed to the right on the Lead's View Order page, for example:
Airbnb doesn't actually collect the money unless there is an issue, unlike the other channels in above examples. (where you actually charge that amount and will refund after checkout if all is good)
Damage fee, if any, is to be handled on a case-by-case basis via Airbnb Resolution Center, and it will not be displayed in PMP's View Order.
For more details, you can refer to this article from Airbnb about their security deposits.
Note: If you split payments, Vrbo's business model charges the security deposit on the second payment and does not split it evenly between payments.
Hope it helps, and please let us know if you have further questions via pop-up chat on the bottom right, or via email to firstname.lastname@example.org.
