Pro‑Rata Billing Overview Dedicated Servers, Failover IP Blocks, and Fixed IP Blocks are billed slightly differently from other products we provide. All services delivered through the NoC are aligned to a billing date of the 27th of each month . This means that if you order a Dedicated Server on the 14th of the month, your first invoice will include the service cost from the 14th up to the 27th, plus the full service cost for the following month. As a result, your first invoice may be slightly higher than usual. Billing Date Changes Whilst we would like to accommodate different payment dates to suit customers, we are currently unable to change the service dates for products ordered through the NoC. This is due to the way IP Blocks are handled on Dedicated Servers. We maintain a pool of available IP Blocks, but there may be occasions where the pool is exhausted. When no IP Blocks are available to fulfil an order, the NoC will purchase the required IPs from the datacentre on your behalf . To support this, we operate a credit facility with our partner datacentres, and we must ensure that payment for these IPs is settled with the datacentre the following month. Aligning all NoC‑managed services to the  27th of each month is the only reliable way to ensure that all charges are collected in time for settlement with the datacentres.
