I had the same question and Airbnb was quick and definitive with their response. Hope this helps someone.
***Brief Synopsis***
As long as you reply to inquiries within 24hrs you are good no need to accept or decline but with reservations a reply is not enough because travelers have pre payment involved so a explicit accept or decline IS necessary.
***My question***
Hi I’ve recently listed my place to stay and want to start off on the right foot. Can you definitively answer the following questions?
1) Does responding and declining an inquire affect your listing in anyway? If so what are the ways your listing is affected?
2) Is it better to respond to an inquiry and never specifically pre-approve, decline, or special offer? Or should you decline inquiries that lead to travelers not wanting to book ?
I searched through community post and other resources. Seems there is still some confusion on the topic. I would more than happy post your response to help the community with a definitive answer!
Thanks
*** Airbnb’s Response ***
Hi there-
My name is Will and I am a fellow host, Airbnb certified expert, and it is my pleasure to assist you now.
The difference here is between an inquiry (which is just a question) and a request (which is based with payment).
A request requires you to click on Accept or Decline within 24 hours, a message back to the guest is not enough.
The reason for this is that the guest has already made a pre-payment at your listed price and Airbnb has to know what to do with the money. So that the charge is not held indefinitely, you have 24 hours to click on accept or decline, so the charge is finalized or voided. If you do not do so, the request auto-expires and the charge is voided and your response rate and tie is affected.
An inquiry (always marked as inquiry in the message thread and email notification), is just a question and involves no payment by your guest. So, a message back is sufficient there. No need to click on pre-approve or decline.
I hope that clarifies and helps you on your future bookings!
Will
