Abstract: An order assistance apparatus includes: a display control unit configured to display sales information that has accepted the selecting operation with an addition of the number of orders corresponding to the number of times of the selecting operations in question; and a determination unit configured to determine whether or not the number of orders in question is equal to or greater than an upper limit value, in which when the number of orders is smaller than the upper limit value, the display control unit updates a display of the number of orders added to the sales information that has accepted a selecting operation by a value obtained by adding a number corresponding to the single selecting operation to the number of orders in question, and clears the number of orders in question when the number of orders is equal to or greater than the upper limit value.
