I. Hainan State Farms Group: The Main Force of State-Owned Enterprises and Industrial Pioneer in Free Trade Port Construction

Hainan State Farms Group is Hainan's largest state-owned agricultural enterprise cluster, with a profound history and massive scale. Its predecessor can be traced back to Hainan State Farms established in 1952, carrying the glorious mission of safeguarding national strategic material supply and developing and building Hainan. After years of reform and development, the group has formed a diversified industrial layout centered on natural rubber, tropical fruits, tropical crops, livestock breeding, tourism real estate, and financial services, with numerous secondary subsidiaries and production bases, long business chains, complex transaction scenarios, and huge procurement scale.

As a pioneer in the construction of the Hainan Free Trade Port, Hainan State Farms Group's operational efficiency and management modernization directly affect whether it can fully unleash industrial potential and seize the opportunity of customs closure. This tax digital upgrade for the centralized procurement platform is one of the group's core measures to promote lean internal management and align with high-standard external trade and tax rules, aiming to solve pain points such as low invoicing efficiency, scattered tax management, and difficulty in precisely unifying policy application under the traditional model, laying a solid compliance and efficiency foundation for the group's large-scale and international expansion after customs closure.

II. Customs closure dividends drive management upgrades, and digitalization solves group tax management challenges

The Hainan Free Trade Port's port closure operation model of "first-line liberalization, second-line control" aims to achieve free and efficient flow of goods, capital, and personnel. For large enterprise groups like Hainan State Farms Group with long industrial chains and many transaction entities, this transformation means that their tax management must achieve a fundamental shift from decentralized to centralized, from manual to automated, and from lagging to real-time.

The core goal of the "Centralized Procurement Platform - Tax API Direct Invoicing System" built through this tender is to achieve cloud-based centralized invoicing management. After the project is completed, centralized procurement transaction data covering all business segments of the group will achieve seamless direct connection with the tax system and automatically generate digital electronic invoices. This will not only free finance personnel from heavy manual entry and verification work, greatly improving efficiency and eliminating human errors, but also ensureCentralized procurement platformThe standardization and consistency of tax handling for all transactions provide reliable data support and an operating platform for group-level unified tax planning and precise enjoyment of multiple preferential policies such as free trade port income tax and turnover tax.


III. Kailing Technology precisely responds to core needs with an integrated cloud solution

The solution Kailing Technology won the bid for is deeply customized around Hainan State Farms Group's core needs of "single tax number, cloud deployment." This solution is not a simple tool replacement, but a comprehensive service system integrating automated processing, real-time monitoring, and intelligent analysis:

1. Automated invoicing service: The system automatically obtains full-chain data such as orders, receipts, and settlements from the centralized procurement platform, and generates fully digitalized e-invoices with one click according to preset rules, realizing "invoicing upon transaction," with processing efficiency expected to increase by more than 300%.

2. Output VAT invoice supporting interface services: Provide a stable and secure standardized API interface group to ensure data connectivity between the centralized procurement platform and the electronic invoice service platform of the State Taxation Administration, and support concurrent processing of massive transactions.

3. Fully digitalized credit limit query API service: This is a key innovation. The system can query the group's available invoice credit limit in real time and perform dynamic alerts and intelligent scheduling, ensuring that invoicing capability is never interrupted even if business volume surges after customs closure, and safeguarding smooth supply chain operations.

4. Fully digitalized e-invoice red-letter confirmation form interface service: Fully online processing of the invoice red-flush process, online collaboration with suppliers to complete red-letter confirmation, making the complex error-correction process simple and traceable, greatly reducing compliance risks.

5. Comprehensive implementation and O&M services: Kailing Technology will provide full-cycle services from business research, system deployment, and integration to personnel training, ensuring smooth go-live and continuous optimization of the platform.


IV. Build a benchmark for business-finance-tax digital transformation of free trade port state-owned enterprises

The successful winning of the bid and implementation of this project is, for Kailing Technology, a dual verification of technical strength and industry understanding; for Hainan State Farms Group, it is a strategic choice to enhance core competitiveness and embrace the new era of customs closure. It clearly demonstrates how, under the special policy environment of the free trade port, large enterprise groups can reshape operational processes, strengthen risk control, and precisely capture policy dividends through cloud-based, centralized, and intelligent tax management.

"We are honored to join hands with a free trade port industry leader like Hainan State Farms Group," said the project leader of Kailing Technology. "This project aims to build for it future-oriented core business-finance-tax digital capabilities for trade forms. Our solution ensures a high degree of unification, automation, and compliance in tax processing at the group level, enabling management to grasp tax conditions more clearly and in real time, so as to focus more calmly on strategic development and fully seize the historic opportunities of the free trade port."

This cooperation between Kailing Technology and Hainan Agricultural Reclamation Group provides a replicable and referenceable transformation model for many large state-owned enterprises and diversified enterprise groups in the free trade port area, signaling that a profound transformation in business-finance-tax management driven by data will accelerate across the island, injecting strong "digital momentum" into the high-quality development of the Hainan Free Trade Port.
