Under China Golden Tax Phase IV, how can large enterprises take the lead? Kailing Technology's "fully digitalized e-invoice Leqi interface" solution accelerates the intelligentization of business-finance-tax management

With the deepening advancement of "tax governance by data" under China Golden Tax Phase IV, the popularization of fully digitalized e-invoices and the opening of the State Taxation Administration's "Leqi" Direct Connection platform mark that tax management has entered a new stage of "real-time data interoperability and precise business supervision." For large group enterprises, whether they can efficiently and compliantly connect directly to the official "Leqi" platform has become a key benchmark for measuring their business-finance-tax digitalization level and core operational efficiency. This is not only a mandatory question for responding to regulation, but also a strategic opportunity to drive business innovation and build future competitiveness.

I. Facing core challenges head-on: the complexity and high risk of self-developing integration with the official "Leqi" interface

The "Leqi" platform provides eligible enterprises with an official channel directly connected to the tax system. However, obtaining access qualification is only the first step; the real challenge lies in the subsequent technical integration and business integration. Enterprises' self-developed integration faces multiple practical difficulties:

1. High complexity of process design and development:Complex business processes such as invoicing and red-letter reversal must be fully designed, and the invocation logic for dozens of Leqi native interfaces must be developed independently. Any sequence or parameter error may cause failure.

2. Cumbersome validation logic and format processing:Must independently implement all invoice data validation rules and complete the synthesis and packaging of XML into PDF/OFD layout files, which involves a heavy workload and low fault tolerance.

3. Concentrated testing and operations pressure:The 72-hour sandbox testing window is urgent, requiring extremely high response speed. After going live, continuous follow-up on interface upgrades and response to policy changes are also required, necessitating long-term investment in professional development and operations resources.

▶ For large enterprises, investing the core team's energy into such high-barrier, non-core professional fields often means high time costs, labor costs, and uncontrollable project risks.

II. Kailing Technology positioning: a professional "Leqi" connection service provider and solution partner

Kailing Technology does not provide a "Leqi interface"; what we provide is one-stop service and a mature solution to help enterprises successfully apply for, efficiently connect to, and stably operate the official "Leqi" platform. We are committed to being a professional extension of enterprise business-finance-tax digitalization teams, resolving connection challenges and letting enterprises focus on business value itself.

1. Qualification application and coordination services:Provide full-process professional services from condition assessment, material preparation, and application submission to communication and coordination with the tax bureau. Enterprises only need to cooperate with seal use, greatly shortening the access cycle and reducing communication costs.

2. Technical integration "turnkey" project:Provides a complete technical solution including architecture design, private deployment, fixed IP, and security compliance configuration. We encapsulate the complex native Leqi interfaces into standardized business interfaces that enterprises can easily call, and are responsible for completing sandbox testing and production launch, achieving "move-in ready."

3. Source code delivery and continuous operations and maintenance:The solutions we deliver support full source code transfer, ensuring enterprises' technological independence and controllability. At the same time, we provide professional SLA operations and maintenance support to ensure stable system operation and to respond to official interface upgrades at any time, giving enterprises peace of mind.

4. Empowerment through mature scenario-based solutions:Based on the practices of a large number of leading enterprises, our solutions can quickly integrate into core enterprise scenarios:

◦ Output automation: seamlessly connects with SAP, Oracle, Yonyou and mainstream OA systems, achieving a closed loop from business orders and contracts to automatic invoicing via Leqi, delivery and payment reconciliation.

◦ Input automation: building an invoice pool through OCR, mobile collection, and direct connection to the tax digital account, achieving full-process automated management and risk control of invoice collection, verification, reimbursement, and selection certification.

◦ Business-finance-tax-archive integration: ensures compliant archiving of fully digitalized e-invoice source files, connecting the data flow across business, finance, tax, and electronic accounting archives to meet management and audit requirements.

III. Outlook on quantifiable benefits for enterprises

Choosing professional integration services delivers value directly across every aspect of enterprise operations:

• Efficiency leap:Financial invoicing manpower release can reach up to more than 70%, and the process from business to invoice is shortened from "days" to "minutes," significantly accelerating cash collection.

• Controllable risk:Systematic verification replaces manual review, basically eliminating risks such as duplicate reimbursement, fraudulent invoices, and delayed red-letter reversals, building a solid tax compliance firewall.

• Cost optimization:Reduce dependence on tax-control equipment, paper processes, and dedicated positions to achieve explicit cost reduction; a unified control platform greatly reduces collaborative management costs for group enterprises.

• Decision empowerment: Full-volume, real-time invoice data becomes an enterprise data asset, providing precise support for supply chain analysis, customer insights and business decisions.

In the wave of the national effort to advance the digital upgrading of tax collection and administration, the "Leqi" Direct Connection is the official bridge for enterprises to reach smart business-finance-tax. Building a bridge on one's own is fraught with difficulties, while choosing an experienced "professional bridge-building partner" is the wise choice.
