Win in the fully digitalized era! Kailing Technology's fully digitalized Leqi solution breaks the dilemma of enterprise business-finance-tax transformation

With the deepening advancement of the digital transformation of tax collection and administration, the State Taxation Administration launched the "Leqi" platform (NaturalSystem) as the core vehicle for direct tax-enterprise connection, providing eligible enterprises with tax-related services such as fully digitalized e-invoices with open rules and unified standards. The core goal of this policy measure is to achieve large-scale, automated, and compliant processing of tax-related business by opening a direct connection channel between the tax system and enterprises' own information systems, deepening the "streamlining administration, delegating power, improving regulation, and upgrading services" reform, and optimizing the business environment.

According to official policy standards, Leqi services cover two types of entities: direct connection units and user units. Direct connection units must be group headquarters or actual controlling entities, bearing responsibility for platform integration, supervision, and data security; user units are subordinate or affiliated enterprises of direct connection units, subject to supervision by direct connection units and required to upload tax-related data as required. Regarding access, the policy sets clear strict qualification thresholds: direct connection units must meet basic conditions such as tax credit rating A/B, a certain scale of revenue and invoice volume, and no major tax violations, and must also possess professional IT operation and maintenance capabilities and data security assurance capabilities; livelihood-related industries may have appropriately lowered access standards, reflecting policy flexibility. The implementation and promotion of the policy marks that in the era of fully digitalized e-invoices, Leqi Direct Connection has become an inevitable direction for large enterprises and group enterprises to achieve business-finance-tax digital upgrading, but it also imposes higher requirements on enterprises' technical adaptation and compliance management capabilities.

I. Pain points in fully digitalized Leqi connection are prominent, making enterprise transformation difficult

In the practice of Leqi Direct Connection, enterprises generally face multi-dimensional difficulties, with every step from technical integration to underlying operations full of challenges.。

Pain point 1: High technical threshold and complex integration process.

Leqi only provides basic core interfaces, and enterprises need to adapt and develop the entire business process themselves, especially reverse processes such as red-letter invoice application, confirmation, and cancellation. A slight deviation in the interface call sequence will cause the operation to fail. At the same time, enterprises need to develop a full-featured operation interface covering permission management, invoice issuance, approval statistics, etc., which places extremely high demands on UI/UX design and software development capabilities, and most enterprises are unable to handle it.

Pain point 2: Cumbersome validation logic and high trial-and-error costs.

Every parameter passed in invoicing data must meet strict validation standards, while the Leqi interface only returns a simple "success/failure" result without clarifying the error reason, making troubleshooting extremely difficult. In addition, business-level validation risks such as commodity code matching, tax rate adaptation, and customer information validation must all be borne by the enterprise itself, and any deviation may trigger tax compliance issues.

Pain point 3: Difficult layout file composition and insufficient adaptation capability.

After invoice issuance, Leqi only returns the upload status. Layout files such as PDF, OFD, and XML must be synthesized by the enterprise itself, and technical difficulty rises sharply in complex scenarios such as multi-line details, merging and splitting, and remark concatenation. If tax bureau preset templates are used, extensibility is insufficient, making it difficult to adapt to diverse enterprise business needs.

Pain point 4: Complex adaptation to multiple invoice types and sharply increased development costs.

Different invoice types differ significantly in validation logic, format specifications, and process parameter passing. Enterprises need to separately sort out processes and repeatedly develop and test for each invoice type, greatly increasing time and labor costs and making project timelines difficult to control.

Pain point 5: Strict sandbox testing and easy delays in go-live progress.

Sandbox testing requires completing testing of all activated capabilities within 72 hours. Once the time limit is exceeded, the application must be resubmitted and approval awaited, seriously affecting overall project progress. This places extremely high demands on enterprises' test organization capabilities and problem response efficiency, and most enterprises find it difficult to complete full-process testing within a short time.

Pain point 6: Poor system integration and severe data silos.

The enterprise's existing ERP, OA, contract management and other systems cannot seamlessly connect with the Leqi platform, resulting in fragmented data across contracts, orders, invoicing, and payment collection, making full-chain collaboration impossible and greatly diminishing the value of business-finance-tax digitalization. At the same time, the self-developed model requires huge investment—the upfront investment for output VAT invoice + input VAT invoice integration alone can reach millions—and requires ongoing operation and upgrade costs.

Pain point 7: Prominent compliance risks and difficult data security assurance.

Tax policies are updated frequently, and self-developed enterprise systems can hardly adapt quickly to new regulations, making compliance loopholes likely. At the same time, adopting a third-party hosting model may violate the regulatory requirement that "the Leqi system must not be hosted by a third party," and data security and autonomous controllability cannot be guaranteed.

II. Kailing Technology's fully digitalized e-invoice Leqi solution: precise breakthrough, empowering full-link business-finance-tax upgrading

In response to the above pain points of enterprises, Kailing Technology has launched a standardized plus configurable plus privatized full-stack fully digitalized e-invoice Leqi solution, with preset capabilities, intelligent technology, flexible integration, and compliance assurance at its core, achieving ready-to-use Leqi integration and greatly reducing the threshold and cost of transformation.

Solution 1: Full-process preset development, lowering technical barriers.

Kailing Technology has completed in advance the development and presetting of core processes such as blue invoice issuance, full-process red-letter invoice handling, invoice delivery, input collection, selection and certification, and status monitoring, so enterprises do not need to design logic or develop interfaces from scratch. After launch, business can be carried out through a visual operation console, and all process nodes are clear and traceable, completely eliminating dependence on professional technical teams and greatly shortening the project cycle.

Solution 2: Intelligent verification system, reducing trial-and-error costs.

The system has built-in 500+ validation rules covering full-dimension scenarios such as commodity code matching, tax rate adaptation, customer information verification, and invoicing limit control, providing real-time prompts on the front end for specific error causes to help enterprises quickly locate issues. At the same time, for business-level validation risks, the system presets compliance thresholds in advance to avoid invoicing errors and tax risks from the source, achieving 100% invoicing accuracy.

Solution 3: Self-developed layout engine, adapting to complex requirements.

Relying on self-developed layout file synthesis technology, the system can automatically output invoice files in PDF, OFD and XML formats that comply with tax bureau specifications, perfectly adapting to complex scenarios such as multi-line details, merging and splitting, and remark concatenation. At the same time, the engine supports flexible expansion and can quickly adapt to future new invoice type upgrade requirements without additional development costs for enterprises.
