Abstract: Disclosed is a store management system capable of switching between manned or unmanned sales. During the daytime, a clerk or owner stays in a store to allow a customer, who visits the opened store, to purchase goods which are received in a vending machine or are displayed in a showcase. On the other hand, in a state wherein the store is closed at night to provide no reception or store management of the clerk or owner, the customer is able to select and order goods of the vending machine at the outside of a show window of the store using a display device and an ordering/settlement device installed at the show window. The vending machine is operated to dispense the selected goods as soon as the customer pays for the goods, and the dispensed goods are discharged out of the show window via a goods discharge device, such as a conveyor belt, to thereby be provided to the customer.
