In the past, enterprises had dedicated teams for tax management, where invoices were sorted and tax filing forms were prepared after business and financial processing were completed. This approach often led to delayed tax processing, resulting in a heavy workload towards the end of each month. Real-time control of invoice tax risks became challenging, significantly impeding the development of enterprises. However, in recent years, there have been remarkable advancements in the tax bureau system, OCR identification technology, direct connection between tax authorities and enterprises, as well as between banks and enterprises. Additionally, development in electronic archives and other technical aspects have eliminated obstacles in real-time correlation, verification, and filing between invoice data and tax data, business data, financial data, and payment and settlement data. Kingdee Cloud·Xinghan has taken the initiative to integrate with the tax bureau as a whole and establish interfaces with various banks. Several clients, including Zhejiang Communications Investment Co., Ltd. New Austria, Hisense and other enterprise groups have successfully implemented the industry-finance-tax and document integration scheme. These advancements have paved the way for seamless integration and synchronization between tax-related data and other crucial business and financial information, enabling enterprises to operate more efficiently and effectively.
