1 Shekhajorjia guest no show up guest canceled booking but booking.com charged me with commission what can i do? 8 Leandri Klopper Hi Shekhajorija,Thanks for the post. This is an easy one. Booking.com will assume all was in order with the guest paying and showing up unless you mark it otherwise. Here is a link on how to mark a guest as no show:How do I report a no-show? Just remember, if the guest Cancelled (Eg. Cancelled it on the website) and you charged the guest already, then you do have to pay commission. If the guest didn't show up, whether they paid or not, you need to mark it as Not Paid/No Show and you may keep the full payment. Hope this helps!
