How should unused paper and electronic invoices be handled?
A:Unused paper invoices must not be discarded directly; instead, they must be voided by clipping the corners. For electronic invoices, unused invoice number segments must be uploaded to the Ministry of Finance E-Invoice Integrated Service Platform for recordation within 10 days of the start of the next period.
