A sheet processing apparatus in the present invention operates in a self-service mode, in which a user does not receive operation support provided by an operation assistant, and a non-self-service mode, in which the user receives the operation support. The sheet processing apparatus includes an inlet that takes in sheets in a deposit process, a transport section that transports the sheets taken in from the inlet, storage sections that store the sheets transported by the transport section, and a control section that causes the transport section in such a way as to transport the sheets to the storage sections on a basis of storage conditions for storing the sheets in the storage sections. The control section changes the storage conditions for at least one of the storage sections between the self-service mode and the non-self-service mode.
