How exactly should group enterprises implement a Leqi solution? Kailing Technology provides a full-lifecycle solution

In the wave of digital transformation, group enterprises face multiple challenges in tax management compliance, efficiency improvement, and data security. The "Leqi Direct Connection" project launched by the State Taxation Administration enables automated tax processing through direct connection between enterprises' own systems and the tax system, becoming the key to solving these challenges. As a comprehensive business-finance-tax digitalization service provider, Kailing Technology, with its full lifecycle solutions, helps group enterprises efficiently connect to the Leqi platform and achieve business-finance-tax integrated upgrading.

I. Leqi Direct Connection policy interpretation: driven by both compliance and efficiency

Leqi Direct ConnectionIt is a tax-related service platform with open rules and unified standards provided by the State Taxation Administration for eligible enterprises. By directly connecting an enterprise's own information system with the tax system, Leqi Direct Connection enables full-process automation of fully digitalized e-invoice issuance, collection, verification, deduction, and more, significantly reducing enterprise tax compliance costs and improving collection and administration efficiency. In 2025, policies further lowered the entry threshold. For example, Beijing adjusted the application threshold from a cumulative invoice volume of 50,000 invoices or an amount of 500 million yuan to 10,000 invoices or 100 million yuan, covering more group enterprises.

II. Pain points of group enterprises: decentralized management and compliance risks coexist

1. Difficult centralized control: Invoicing processes across multiple branches are dispersed, data verification is difficult, and the group finds it hard to manage uniformly.

2. Low efficiency: traditional invoicing methods are time-consuming and labor-intensive; enterprises issuing tens of thousands of invoices annually face enormous manual pressure.

3. Compliance risks: Invoice processing involves many steps, and manual operations can easily lead to errors such as false invoicing and duplicate reimbursement.

4. System fragmentation: Data silos among business, finance and tax systems make business-finance-tax collaboration difficult.

III. Kailing Technology full-lifecycle solution: precise implementation in four major stages

Based on years of industry experience, Kailing Technology has built a full lifecycle service system covering "requirements analysis - system integration - implementation and deployment - operations support" to help group enterprises smoothly connect to the Leqi platform.

1. Requirements organization and planning

▪ Digital diagnosis: analyze the enterprise's existing system architecture, assess the feasibility of Leqi Direct Connection access, and formulate a personalized upgrade plan.

▪ Policy Adaptation: Combines the latest policy requirements to clarify the rights and responsibilities of direct connection units and user units, ensuring compliance.

2. System Integration and Development

▪ Multi-system integration: direct connection with mainstream ERP systems such as SAP and Yonyou, enabling automatic synchronization of order data to the invoicing module, intelligent coding, and automatic issuance of fully digitalized e-invoices.

▪ All invoice type support: covers new invoice types such as railway electronic passenger tickets and air transport electronic passenger tickets, and adapts to multi-channel invoicing via Golden Tax disks, tax control disks, UKeys, and more.

▪ Security protection: Use national cryptographic algorithms to encrypt data transmission and ensure stable system operation.

3. Implementation Deployment and Testing

▪ Sandbox testing: Lead testing in the Leqi sandbox environment, verify system functions and stability, and ensure passing tax authority acceptance in one attempt.

▪ Dual-track operation: during the transition period of "fully digitalized e-invoices + paper invoices", supports mixed invoicing modes to meet diverse customer needs.

4. Operations and maintenance support and iteration

▪ Continuous upgrades: following the tax system's biweekly iteration frequency, quickly responding to policy changes and ensuring service continuity.

▪ Risk Monitoring: Built-in 30+ industry indicators, real-time alerts for abnormal invoices, supplier risks, etc., reducing tax risks.

IV. Technical advantages: dual assurance of automation and data security

1. Full-process automation

▪ From sales order to invoice issuance, booking, and archiving, the entire process requires no manual intervention. For example, a central state-owned enterprise improved document processing efficiency by 60% and reduced manual archiving costs by 70% through integrating the SAP system.

▪ Batch selection authentication and automatic generation of accounting vouchers, reducing finance accounting workload.

2. Data Security and Compliance

▪ Blockchain technology stores evidence of contract flow, fund flow, and invoice flow to ensure data traceability.

▪ Monitor invoice status (voided, red-ink reversed) in real time, block duplicate reimbursement, and lock risky invoices with one click.

For group enterprises, accessing the Leqi platform is not only an iterative upgrade of the technical architecture, but also a systematic innovation of the management model. Relying on leading technological advantages, senior industry experience, and full-chain service capabilities, Kailing Technology builds a one-stop service system for enterprises from needs diagnosis and solution implementation to continuous operations and maintenance, helping enterprises achieve leapfrog improvements in tax management efficiency within a compliance framework.
