By putting Invoice encrypted information database first, we can announce invoice across types, implement lottery invoice system, promote the tax information consruction, and guide consumers to actively ask for and regularly use invoice.In the process of design and development, this system mainly develops the integrated part of source data for the invoice. In front of a large number of VAT invoices source data for each system, how to quickly integrate, efficiently use, completely analyse and rapidly response the entire system is essential to the successful development. The system consists of the following three parts: the VAT lottery invoice management, VAT invoice circulation monitoring and VAT invoice authenticity verification. We can implement lottery invoice system by transferring part of the tax to the consumer in the form of bonuses, and stimulate the consumers' enthusiasm of obtaining the invoice, to reduce the chance and possiblity that businesses issue no or less invoice, and preventing the loss of tax revenue.We can effectively monitor the invoice circulation process by computer technology, help tax personnel quickly and effectively lock problematic invoice and gather doubtful invoice information data to form doubtful taxpayers inventory which can be issued to the grassroots tax authorities to have tax assessment in order to investigate and deal with the illegal behavior of illicit reselling invoice; Extranet invoice authenticity verification module mainly provides the authenticity verification inquiry service for the invoiced individuals and companys. Heilongjiang Province VAT invoice management and control syste m is the key to help tax officials solve tax problems in the work and further to implement "control tax according to invoice".
