Published: 2025-06-10 17:22

Against the backdrop of China Golden Tax Phase IV and the era of fully digitalized e-invoices, tax digital management has become a key part of enterprise operations. With professional, efficient, and reliable corporate business-finance-tax digitalization solutions, Kailing Technology is committed to helping enterprises easily achieve Leqi tax compliance management.


I. Interpretation of Leqi Value and Concepts

Leqi (NaturalSystem) is a tax-related service platform provided by the State Taxation Administration for eligible enterprises, aiming to achieve direct connection between the tax system and the enterprise's own information system and bring enterprises tax-related services such as fully digitalized e-invoices. Unlike RPA, Leqi replaces facial recognition authentication with a fixed IP address and, combined with the advantage of offline invoicing, can issue invoices 24/7/365, responding to the national call and supporting the work of the competent tax office/bureau.

II. Leqi application process overview

Direct connection units that meet the requirements shall, in accordance with the principle of territorial management, initiate an access request to the competent tax authority through the Leqi platform and submit the Leqi Direct Connection Service Access Information Form, the Leqi Direct Connection Service Agreement,Letter of Authorizationand other requirements of tax authoritiesA series ofMaterials. The access preparation process covers admission management, obtaining ptbh, subscription capability activation, sandbox testing, and formal capability activation.

III. Overcoming Leqi Direct Connection integration difficulties

Integrating Leqi Direct Connection with native interfaces involves many difficult tasks, such as process design requiring enterprises to develop according to invoicing logic themselves, where any incorrect interface call sequence leads to invoicing failure; complex validation logic, where when parameter passing logic is wrong the Leqi interface only returns success or failure, and the validation risks arising from business operations are borne by the enterprise itself; layout file composition and invoice type integration also require additional effort from enterprises; sandbox testing time is limited, and after failure, application materials must be resubmitted and await review; the operation interface must be developed and designed by enterprises themselves, involving numerous functions such as permission management, invoice filling, approval invoicing, invoicing record statistics, invoice delivery, and group reports.



IV. Advantages of Kailing Technology Solutions

Compared with third-party pure APIs and native Leqi integration, Kailing Technology's solution has significant advantages. In terms of process linkage, users do not need to design it themselves; the system has built-in development of all process nodes and provides front-end operation pages, while also transferring the system's process design knowledge and capabilities. Error notifications are more precise, and the operation page can give the final operator specific reasons for non-compliance. Kailing Technology provides comprehensive support in logic point development, layout file composition, multiple invoice types, sandbox testing, customized requirements, and more—whether it's self-developed technology for composing layout files, synchronous upgrade services, or providing configuration/standardized functions and custom development services, it can meet the diverse needs of enterprises.

V. Comparison of Leqi self-development and third-party development

Enterprises independently carrying out Leqi adaptation work must invest substantial manpower and capital costs. Looking only at the self-developed integration step, labor costs and R&D costs are already high, and in addition, the upgrade and transformation costs of the Leqi interface also...Requires separate calculation, overall investmentExtremely high cost

Entrusting a professional vendor, such as Kailing Technology, to undertake this task can greatly save time and cost while also ensuring that the enterprise itself has management capability and achieves independent controllability, thereby meeting the relevant requirements of the State Taxation Administration. Kailing Technology is highly experienced in Leqi integration, with high product maturity and close alignment with business scenarios. Project team members all have many years of work experience in the business-finance-tax industry, and core members have experience in Leqi implementation, fully digitalized e-invoice projects, and finance system integration. Its operations and maintenance advantages are obvious, with dedicated personnel for dedicated operations and maintenance and rapid problem response, ensuring subsequent project upgrades and operations and maintenance quality.

Common Questions
What is the difference between Leqi Direct Connection and RPA?
Leqi (NaturalSystem) is a direct connection platform provided by the tax authority, using a fixed IP instead of facial recognition authentication and supporting 365×24 uninterrupted invoicing; whereas RPA simulates manual operations and cannot achieve all-weather automated invoicing. Leqi is more stable and efficient, and complies with China Golden Tax Phase IV requirements.
Is the Leqi application process complex? What materials need to be prepared?
The process includes access management, obtaining ptbh, subscription capability activation, sandbox testing, and official activation. Materials such as the "Leqi Direct Connection Service Access Information Form," "Leqi Direct Connection Service Agreement," and authorization letters need to be submitted, initiating access requests to the competent tax authority according to territorial management principles.
What connection difficulties can Kailing Technology's Leqi solution solve?
Kailing Technology has built-in process design, requiring no user self-development; provides precise error reminders to avoid verification risks; supports layout file composition, multiple invoice types, sandbox testing, and customization needs, reducing self-development costs and ensuring rapid go-live.
Which is more cost-effective: enterprises building Leqi themselves or entrusting Kailing Technology to build it?
In-house building requires significant investment in manpower, R&D, and upgrade costs, resulting in extremely high overall costs. Entrusting Kailing Technology saves time and cost, with high product maturity, an experienced project team, and fast operations and maintenance response, ensuring autonomy and controllability while meeting tax bureau requirements.
What specific value can Kailing Technology's Leqi solution bring?
The output side connects with business-finance-tax systems, enabling automatic invoicing to improve efficiency and prevent tax risks; the input side achieves automatic invoice synchronization, certification and deduction, connecting the entire business-finance-tax-asset-archive process, reducing risks, improving invoice receipt efficiency, and automatically archiving in compliance with policy requirements.
