GiDiNet service billing is handled automatically according to the methods described below.
This system is adopted to ensure correct accounting and tax handling of advance payments and the services actually delivered.
Advance invoice
An advance invoice is issued for each payment received.
The advance invoice refers exclusively to the recorded payment, because at the time of collection the service has not yet been delivered. It therefore documents the amount paid by the customer as an advance.
Advance invoices are issued individually, one for each payment made.
Final invoice
Subsequently, on an administrative schedule, a final invoice is issued.
The final invoice:
- lists the service or services actually delivered;
- indicates the amounts already invoiced as an advance;
- includes the reference to the related advance invoice(s).
The final invoice may have a total amount of zero, as the amounts have already been invoiced at the time of payment through the advance invoice.
A final invoice may include multiple services and refer to one or more advance invoices, if the related amount was covered by multiple payments.
