Duplication, modification is convenient, is easy the features such as being forged, and relative to paper invoice, the authenticity examination of electronic invoice, which seems, more attaches most importance to
Will with it is urgent.
For the examination for solving VAT invoice (containing electronic invoice), the State Tax Administration establishes national VAT invoice and looks into
Platform is tested, which provides the examination for the VAT invoice issued in 1 year in the whole country.On the platform, examination person inputs
Invoice codes, invoice number, date of making out an invoice, check code (the general ticket of value-added tax, electronic invoice) or the amount of money of making out an invoice (the special ticket of value-added tax)
Corresponding invoice information can be transferred out, then examination person passes through the invoice information provided platform and the hair to be checked for issuing after examination and approval ticket
Ticket information is manually compared, and is obtained invoice and is checked result.
Platform is checked based on national VAT invoice, segmentation scheme has carried out double optimization, supports two in scanning invoice
Dimension code will check, due to the two dimensional code in invoice include examination platform information needed, this scheme be one simplify it is defeated
The examination scheme entered, it is still desirable to the artificial comparison for carrying out invoice content.Since the discrimination of two dimensional code in electronic invoice is far high

Mark data carries out invoice data and transfers, and then by being manually compared, there is no really complete to check work.This kind of scheme exists
Electronic invoice and paper invoice are put on an equal footing when examination, each invoice factor content for not accounting for electronic invoice is can to pass through
The content of electronic invoice pdf document is parsed, to realize the automatic comparison of invoice content.
In addition to above-mentioned invoice examination scheme, some examination schemes, which are provided, carries out invoice solution based on PDF layout files template
Analysis, layout files template contain position of each element in PDF, then by extracting corresponding positions in electronic invoice pdf document
The text set carries out the parsing of each invoice element, is then checked using the element parsed.The problem of this programme is to electricity
The dependence of sub- invoice pdf document pattern, although State General Taxation Administration provides the style specifications of electronic invoice, each electronic invoice manufacturer
Inevitably there is different degrees of deviation when realizing, it is tight that some deviations occur that location-based invoice parsing can
The mistakes and omissions of weight, so as to cause examination failure.
On the other hand, examination shortage is carried out to electronic invoice pdf document based on template to verify the pre- of pdf document itself
Journey can not quickly identify the electronic invoice pdf document of forgery, lead to a large amount of invalid pinging operations, and be easy to be attacked by Does
It hits.
Again, because the pdf document generating process of electronic invoice is that invoice information is uploaded to Administration of State Bureau making out an invoice software
Later, it is voluntarily generated by electronic invoice service platform.Part electronic invoice service platform is because the reasons such as secret protection may
The non-critical data of electronic invoice is hidden or is adjusted when electronic invoice PDF is generated, it is aobvious so as to cause electronic invoice PDF
Therefore difference requires all elements to be checked for issuing after examination and approval ticket to the data of the invoice factor data and invoice bottom account library that show by force
It is consistent with State General Taxation Administration bottom account library to will lead to examination failure in the examination of this kind of invoice.
Finally, the examination of existing electronic invoice merely provide examination whether successful conclusion, do not formed visual
Report, requires accounting etc. the application of original certificate, needs to check people voluntarily from examination platform screenshotss, generating one can
For the subsequent voucher used, this is all that the work of people's examination invoice brings inconvenience, and inefficiency.
