Bill payment systems rely on careful integration with existing billing databases, and can be used for a variety of bill-collection purposes.
For payments of up to £5, credits can be lodged against an account by
Dialling a single-drop 09xx number
For higher variable amounts, and where payment requires debit/credit card details to be entered, an IVR menu system will guide customers to enter their account information, as well as take card details once the outstanding balance on the account has been confirmed for payment by the customer.
