Revelation Pets offers a Check In/Out button on the dashboard, the Arrivals and Departures Reports and on every booking.
When the Check In / Out button is clicked, the arrival and departure times are updated respectively on the booking.
When a pet is checked in, the booking turns turquoise on the calendar and, when the pet is checked out, it turns pink.
Please Note: this function does not work if the arrival or departure date is different to today's date. If the date of the booking changes, open the booking, press 'Edit Booking', change the dates and press Save.
