Problems solved by technology

Due to reasons such as privacy protection, some electronic invoice service platforms may hide or adjust the non-critical data of the electronic invoice when the electronic invoice PDF is generated, resulting in differences between the invoice element data displayed in the electronic invoice PDF and the data in the invoice ledger database. , therefore, forcing all the elements of the invoice to be inspected to be consistent with the State Administration of Taxation's account database will lead to inspection failure in the inspection of such invoices
[0009] Finally, the inspection of existing electronic invoices only provides a conclusion on whether the inspection is successful, without forming a visual report. For applications such as accounting that require original vouchers, the inspector needs to take a screenshot from the inspection platform to generate a voucher for subsequent use. , this has brought inconvenience to people's work of checking invoices, and it is also inefficient
