The required method of payment or any payment options available will be set out in your Sales Order.
If a Service uses an up-front payment model, you will be charged the entire amount for that Service in advance. If a Service uses a subscription payment model, you will be charged in regular installments for that Service. Installments are usually monthly (payable in advance), but sometimes other periods are available as may be set out in the SalesOrder. Subscription amounts are payable for each period in advance, from the day of the SalesOrder being signed, and then on the same date each month afterward.
The first payment is generally taken within 48 hours of signing the Sales Order, and we will not be required to start performing the relevant Service(s) until the first (or only) advance payment has been received by us in respect of that Service.
