Clients on monthly plans pre-pay for a set number of hours to be used that month. Each month they reset with the base number of hours included in their plan. Most of our Kitchen Administrators bill their Clients for plans on the 5th of the month, but a few bill them on the 15th of the month. This is called the billing date.
During the active month, the Client's bookings on the calendar work toward their base hours, and once they go over their base number of hours, the overage rate(s) kick in for the rest of the month. The overage hours are added up for the remainder of the month and paid on next month's billing date (along with next month's plan amount).
Other items billed on the billing date are storage and any monthly recurring fees.
