How does the monthly billing cycle work?

Every InterPark location is set up with the billing cycle to be on the 1st and the 15th of every month. If your start date is the 15th of the month, your first bill will be for a month and a half. The 1.5 month bill will allow you to park for 1.5 months and gives us time to get you on a 1st of the month billing cycle. After that period, your bill will be for just one month of parking.
