Which direct booking site allows me to approve/deny bookings?

[Hunter Beck]

Hi there,

Are there any direct booking sites with "request to book" capabilities where I have the ability to approve/deny booking requests before they get locked in? I want the ability to approve/deny bookings to my direct booking site before they are made.  

Thanks,
Hunter

my site www.bookvrof.com does not have a "click to book" function, but it is already challenging enough to attract repeat OTA customers to book direct, I do not want to make it harder.  Since I am the owner of the site, I can cancel any bookings I am not comfortable with without any penalty at all.
