Abstract: A service providing server, which provides a product delivery service for delivering a product between terminals located at places different from one another, includes a communication unit that communicates with a plurality of terminals. A user information management unit that manages product purchase information and product delivery information received from the plurality of terminals provides the product purchase information received from a buyer terminal to a deliverer terminal and provides the product delivery information received from the deliverer terminal to the buyer terminal. When a terminal corresponding to the product delivery is selected by one of the buyer terminal or the deliverer terminal, a device connection unit connects the terminals to each other for product delivery negotiation.
