Hi Alexander,
It appears you're encountering the standard functionality within Airbnb's system. Airbnb generally does not allow hosts to send money directly to guests through their platform except as part of a reservation change or an official claim on the security deposit post-check-in.
Airbnb does not typically support sending additional payments or issuing partial refunds directly without altering the reservation details. This is primarily for security and auditing purposes, to ensure that all transactions can be tracked and associated with specific bookings.
Given the limitations and potential complications of handling money outside the Airbnb system, it’s often safest to contact Airbnb support directly to ask if there are any current features or workarounds that may apply to your situation.
By adhering to Airbnb’s structured processes, you ensure that all transactions are properly documented and covered under Airbnb’s terms of service, which is important for both host and guest protection.
I hope this helps!
All the best,
Upfish Management
