Barkley HQ allows you to change your booking time and employee from simply dragging it from the calendar or going into the booking itself.

Within the same day:

If you are moving your booking within the same day to a different time or employee, simply drag and drop the booking into the new time slot.

Different day:

If you are moving the booking to a different day, you may change the time within the Booking Wizard’s Time and Employee by double clicking on the booking or by searching it. Once the new time and date is set, click Save.
