What can I do if I forgot to click the no show button before expiry.

Hi Ted and welcome to the Partner Community.

I would suggest to you to contact immediately booking.com because you will probably have to pay commission...

Wish you well.

Hi

It is usually enough to include the reference and action request note in a message.

In the Finance Menu, Docs & Invoice, you can tick dispute line item [a reservation]  in the reservations list.

Message or Call BdC PartnerSupport
