Next-day delivery refers to delivery on the day following the order, while same-day delivery means delivery on the same day as the order.
Step-by-step explanation:
Next-day delivery and same-day delivery are options provided by businesses to meet the varying needs of customers.
Next-day delivery refers to the delivery of a product or service on the day following the placement of an order. It allows customers to receive their items quickly, often with an additional fee for the expedited service.
Same-day delivery means that the product or service will be delivered on the same day as the order. It is particularly beneficial for urgent needs or when customers require immediate gratification.
