First, the characteristics of electronic invoices

Electronic invoice is a new form of invoice with the development of information technology, which has the advantages of convenience, high efficiency and environmental protection.

Some places or industries may require that electronic invoices must be stamped to have legal effect. Therefore, in actual operation, it needs to be judged according to the specific situation.
