This is the old version of quota invoice, and the new quota invoice has changed the invoice header: 20 19, the new version of general machine invoices (ordinary invoices), the header is provincial+general machine invoices, and the old version is provincial+state taxation bureau+general machine invoices.

If the invoice date is 19, it can be used for accounting, and if it is before 19, it is best not to use it.

Hope to adopt, thank you.
