The appointment accessorial should be selected when you require a specific or limited time frame for your pick up or delivery. Anything that is outside of Monday to Friday 9 am to 5 pm should select an appointment accessorial. When that option is selected the carrier will call and arrange an agreed-on time frame for the delivery or pick up. IF you select the option at the time of quoting any applicable fees for the accessorial will automatically be added to the rate quote. IF you book your shipment without selecting the accessorial and the fee does apply you will be additionally billed for the service or location. Additionally, if you book without the accessorial the truck may show up outside of the locations available hours and therefore incur a dry run fee or re-delivery fee.
