        In some countries, the smallest coins do not exist. For example, in Switzerland, there is no coin for 0.01 CHF.
        For this reason, if invoices are paid in cash, you have to round their total amount to the smallest coin that
        exists in the currency. For the CHF, the smallest coin is 0.05 CHF.

        There are two strategies for the rounding:

        1) Add a line on the invoice for the rounding: The cash rounding line is added as a new invoice line.
        2) Add the rounding in the biggest tax amount: The cash rounding line is added as a new tax line on the tax
        having the biggest balance.
