Electronic invoice system does not support manual voiding. If there is an error in returning goods or issuing electronic invoices, the drawer shall issue red-ink invoices for verification. The red-ink invoice issued by electronic invoice should be consistent with the corresponding logistics and capital flow information.

Invalid special invoices are treated as "invalid" in the anti-counterfeiting tax control system, and each copy of paper special invoices (including unprinted special invoices) is marked with the word "invalid", and all copies are retained.
