Abstract: Systems and methods for a modular configuration of dispensing modules of a vending machine are provided. The vending machine includes a grid of mounting modules to which the dispensing modules can be removably attached. Accordingly, the arrangement of dispensing modules can be readily modified to accommodate different sized items. Some items may be placed across two dispensing modules that are operated in parallel to dispense the item. The dispensing modules may also include an indication unit. The indication unit can be used to provide assistance to servicepersons during a restocking event.
