Direct Booking Tool -- For Repeat Guests

I am popular and have a number of guests who repeat book. Does anyone know of a tool / software which allows them to book directly but also integrates with Airbnb. Specifically, it would check pricing, availability from my Airbnb account and then block rooms once reservations are made.

Thank you.

I also have a lot of repeat business, and I simply invite people to contact me by direct email if they wish to return.

I request the email address of every guest, and keep it in a client spreadsheet. I also keep the phone numbers and all other relevant info.

I don’t know if there is some software that does this, but to me, it’s still only about 15%- 20% so not worth any investment from me yet.
