Let your customers choose their preferred date and time to receive the delivery of purchased products. They can even place a comment while placing the order.
Manage the delivery of your sold products by allowing your customers to choose their preferred delivery date.
Due to this there won't be any conflict for missed deliveries or customer is not present to accept the delivery.
Your customers won't be able to add date or time manually. They have to choose from the options available.
Thus you have the control on which date or time slot to be available for selection. Hence it becomes easy to manage your product's delivery schedule.
