An accounting device according to an embodiment includes an input device that receives an instruction to start a job. A first display device includes a first screen facing a first direction towards a person who operates the input device. A change machine includes a depositing port for receiving money and a dispensing port for dispensing money. A second display device includes a second screen facing a second direction different from the first direction and towards a person who deposits money into the depositing port or receives money from the dispensing port. When the instruction received by the input device is to start a predetermined job that is different from the accounting transaction and that includes depositing money into the change machine or dispensing money from the change machine, the processor causes information supporting execution of the predetermined job to be displayed on the second screen.

A system includes a currency counting device communicably coupled to memory and one or more processors. The memory stores instructions that are executable by the one or more processors to cause the one or more processors to cause a first amount of currency to be counted by the currency counting device, wherein the first amount of currency is an actual amount of currency received by a teller money drawer; determine that the first amount of currency is a discrepancy amount different than an expected amount of currency; determine that a teller error is a potential source of the discrepancy based on the discrepancy amount being below a threshold; and cause a display device of a teller computing device to display an indication within a pop-up window that the teller error is the potential source of the discrepancy based on the discrepancy amount being below the threshold.
