Any changes you make that relate to the property and that are displayed on the Orders page will be updated dynamically within seconds. So if you make a change in sq ft for example on your machine, who ever is on the same page on a different machine or location will see the change reflected in a few seconds.
Same applies to scheduling. Let’s assume two people are responsible for scheduling and they are in remote locations. One changes the appointment time then that change will be reflected dynamically on all the Tours pages everywhere.
