  • Publication number: 20240135418
    Abstract: An information processing apparatus calculates a fee for applying a second coating film including an easily removable layer to a first vehicle having a first coating film applied thereon. The information processing apparatus disclosed herein has a controller that calculates a first fee defined as a fee for applying the second coating film to the first vehicle that is for lease lower than a second fee defined as a fee for applying the second coating film to the first vehicle that is not for lease. In other words, the controller calculates the first fee by subtracting a first subtraction value from the second fee.
