The commissionable fee is calculated based on Rate Plan set specifically for the Agent sales channel, so the rate must be entered manually.
Here is an example:
Commissionable fee is set to 10%
Agent Rate Plan is set to USD 1,000 per night
An agent booking is made for 1 night, with a total payment of USD 1,000
In this case, the commissionable fee is 10% of USD 1,000, which is USD 100, and the host will receive the remaining USD 900.
