The format and style of electronic invoices are the same as those of traditional cardboard VAT invoices, and they are displayed in the form of pictures.

Electronic invoice is the product of the information age. Like ordinary invoices, they are distributed to merchants in the form of unified issuance by the tax bureau. The invoice number is distributed to merchants with national unified coding and unified anti-counterfeiting technology. The electronic invoice is accompanied by the signature mechanism of the electronic tax bureau. Due to the development of blockchain technology, electronic invoices are generally in PDF format, which taxpayers can download and store in other electronic storage media such as mobile phones and mailboxes, and browse and print through PDF software systems when necessary.
