The electronic invoice can't be sent out. The error of authorization code is related to the wrong input of authorization code, the low version of invoice software and network problems.

1, the authorization code is entered incorrectly. Please confirm that the authorization code entered is correct, and pay attention to the case and input errors.

2. The version of billing software is too low. The billing software needs to be updated in time, otherwise the electronic invoice may not be issued normally.

3. Network problems. Sometimes problems such as poor network connection, busy network or abnormal server may also lead to incorrect prompt of authorization code in the process of issuing electronic invoices.

Electronic invoice refers to the electronic invoice generated in the transaction process, which is different from the traditional paper invoice. Usually, electronic invoices are recorded, invoiced, signed and accepted by computer systems.
