If your Bookings are set for manually approve bookings, there are several ways how you can find out, that a new booking was made (if this option is untagged, only the number of received bookings will change in the field of the corresponding event).
Now you need to confirm (or reject - it is up to you) the request. You open the event by clicking on it, or clicking the notification including the new booking. An Events window with following information appears:
At the end of this line, you will also find an option to Confirm or Reject the booking. Just click the one option you want and you will approve or decline it. Reservio automatically sends the client information, whether he can look forward to the event or no.
Next: Cancel booking →
