You have the option of allowing the system to roll forward the frequency of future invoices without affecting the existing invoices. Ordinarily, when you enable roll forward invoicing, going into the fourth week, the first three weeks would be credited back and re-invoiced together with the fourth week as a month. If, however, you decide to decide to Override Rolldown on Roll Forward, the first three weeks will not be credited back, and the fourth week will generate another weekly invoice. Then the remainder of the rental period will be billed at the monthly rate, starting with the fifth invoice. Any unused days that are billed as part of this month will be credited back after the equipment is taken off rent. See Set up Global Rental Parameters. for the steps involved in choosing this option.
