The Bill Configuration option lists your current bill configurations, which are linked to invoice types that store default configuration data for the bills. A bill configuration includes at least one reference number, which the biller provides. The reference number identifies a consumer's account, for example, your account number at the electric company.
To make payments on demand, add a bill configuration using the available invoice types. You can also edit or remove a bill configuration. An invoice issuer can create multiple bills; for example, one issuer can provide bills for electricity and water, and the customer pays separately for each service.
