Your billing cycle is selected at point of sale and is intended to allocate you to the cycle that immediately follows your anticipated service live date. The intention behind this is to ensure that prorating on your first invoice is kept to a minimum (less than one week). On occasion, in the event of a delay during the provisioning process, it can happen that the selected billing cycle is less suitable, resulting in higher than anticipated prorating.
We have four available billing cycles, each 7 days apart from each other - 1st, 8th, 15th and 22nd. Direct debit payments are scheduled to take effect roughly 14 days (10 working days) after your invoice date.
