If capped rental is selected, NikoHealth will continue to generate the billing period(s) without creating new invoices after this rental price option period is met. This would be used for items such as oxygen where you would want to see the current billing period interval. (i.e. If you set a rental price option to expire at 36 months, select the capped rental option and put an interval of 60, NikoHealth will continue to generate billing period(s) until period 60

The difference when creating your price option for a capped rental is that you will need to select the capped rental option on the bottom and fill in the interval end period.
