Run the Preview and create last periodic invoice process to generate a list of the data that will appear on the final invoice in a set of periodic invoices. This is also the form on which you create the actual final period.

A final invoice always states the data below, which are also shown in the different sections of the Preview last periodic invoice form:

• Invoice recommendation lines: This section shows all invoice lines on the invoice recommendation that are ready to be processed when the final invoice is created. If no lines are displayed in this section, this may have a number of reasons:
  • The sales lines have not been marked for periodic invoicing.
  • The sales lines have not been shipped.
  • The shipping note has not been processed (for the invoice recommendation).
  • All sales lines have already been processed in previous last periods.
• Credited periodic sums: This section shows all periodic payments that will be credited when the final invoice is created. When no credited periodic sums are displayed, no periodic invoices may have been created, or all periodic payments have already been processed on previous final invoices.
• Last period results: This section shows the actual sums that will be invoiced to the customer. The result is the difference between the value of the lines on the invoice recommendation and the value of the periodic invoices already issued.

  Also note the VAT result. For invoice recommendations, VAT is calculated using the VAT code specified on the invoice recommendation in question. For credited periods, VAT is calculated using the VAT code specified for the relevant periodic invoices.

Note: This process cannot be used for finalized orders.
