Shenzhen Pingshan: Digital Assistants Power Invoice Management

The Pingshan district tax bureau in Shenzhen has built its own digital toolkit, shifting invoice management from manual switching among systems to analysis driven by big data. Because approval staff had to query and cross-check data by hand, the bureau developed an invoice approval tool on the city bureau's digital innovation platform. It brings 36 review indicators in five categories, covering registration, filing, collection, invoice flows and input-output matching, onto one screen and charts key signals such as input-output matching, tax burden swings, filing continuity and affiliated companies, cutting approval time per case by 60 percent. For fraudulent invoicing, the bureau links invoice, tax, personnel and production data and scans continuously, flagging shell companies through signs such as multiple registrations at one address and VAT burdens below one part in ten thousand, and focusing on newly registered firms issuing their first invoices for agricultural products, building materials or machinery leasing. It has identified gangs that invoice right after registering and then vanish, involving hundreds of shell companies, and referred the leads to audit teams. On internal control, its innovation module embeds indicators such as quota increases beyond the original level, improper quota increases for Class I taxpayers and expired quota adjustments, giving round-the-clock automated alerts coupled with a closed loop of problem lists, rectification ledgers and write-off reviews.
