There are many different charges you can add to a Tariff, which in turn will appear on the bill.
You would create one Tariff with many Cost Definitions.
The Tariff is held under the Contract, and the Cost Definitions can be under the Organisation, Site, Meter etc. It is good practice to add them under the Organisation as they are then accessible in one place.
You will probably have one Contract and a few Cost Definitions attached to the Contract, for example Pence Per Unit, Standing Charge and VAT rate.
See below on how to set these up.
