Invoicing enables us to group billing for several contracts/services/time periods onto one document for presentment to the customer. Invoicing is executed at contract account level, whereas billing is done at the contract level.
During invoicing, other functions can be executed: budget billing calculations, late payment charges, interest, dunning, account maintenance, deposit interest/release, etc.
Existing open items for an account can be included in the invoice document (print document) so that the printout can accurately reflect the customer’s account balance.
Invoicing provides the integration to FI-CA and financial posting. It uses the posting information generated by the billing document.
Outsorting can be performed at the invoice level, for example if the invoice amount is above or below a threshold.
Invoices can be reversed (which also reverses the financial postings).

The scenario in this unit deals with test invoicing.
A customer has made a payment within the current billing period and was billed according to the corresponding rate. The customer also wishes to receive an interim bill.
Another customer receives a bill but is not in agreement with the meter reading results billed. The meter reading results are too high. Invoicing and billing are reversed (full reversal). An adjustment bill is created.
