Leqi only provides interface "parts"; business processes, reverse red-letter reversal, various verifications, layout encapsulation, and invoice type adaptation all have to be developed by enterprises themselves

The State Taxation Administration's "Smart Tax" innovation model, a one-stop service platform featuring tax-enterprise data interconnection and dual openness of "data + rules"
Through tax-enterprise data interconnection, it gradually evolves into data interoperability among government departments, between government and enterprises, and between enterprises, providing taxpayers and the government with one-stop service access, subscription, use, and supervision.
Owner of the direct connection platform, main responsible entity — head office, group headquarters, actual controlling entity with equity control relationships; interfaces with Leqi, supervises user entities, reports tax-related data, and bears data security responsibility.
Affiliated enterprises invited or authorized by the direct connection entity to use Leqi services; the direct connection entity may authorize affiliated enterprises or third-party enterprises to build and manage the platform.
With Direct Connection to Leqi, full capabilities including blue invoices and red invoices, credit limits, batch invoicing, and group reports are independently controllable, without relying on third-party platforms.
Data resides in its own systems and own servers, meeting the high requirements of state-owned enterprises and large groups for data security and independent controllability.
Complies with the State Taxation Administration's commitment that "Leqi-related systems do not use third-party hosting," with clear rights and responsibilities and legal compliance.
Three thresholds—invoicing volume, amount, and industry—Kailing helps you verify eligibility, prepare materials, and coordinate with the tax bureau
Leqi only provides interface capabilities; business logic, reverse processes, and verification risks are all borne by enterprises themselves
All self-owned business systems are developed in-house, and Leqi only provides interface capabilities; reverse processes must be designed independently, and a single error in interface call sequence will cause invoicing failure.
The full-chain reverse process of red-letter confirmation forms and reversals is complex, requiring self-designed handling of various exception branches.
Every parameter passed has validation and requires substantial development; business validation is not handled by Leqi (wrong tax number, code and tax rate mismatch, etc.), and risks are borne by the enterprise itself.
The packaging rules for invoice layout files (PDF / OFD / XML) are cumbersome and need to be implemented and validated one by one.
The validation, format, process, and parameter passing differ for different invoice types and 20 types of specific-element invoices, making type-by-type development an enormous workload.
Time-limited invoice sandbox testing is under great pressure; you also need to develop your own business interfaces for permissions, filling, approval, record statistics, delivery, group reports, etc.
In-house development requires large investment, a long cycle, and self-borne risk; external procurement saves time and money, but full source code delivery and independent controllability must be required
From document submission to source code delivery, the entire process is compliant, turnkey, and independently controllable.
Full package for Leqi material preparation, filing, and coordination and communication with the tax authority; the client only needs to cooperate with printing materials + stamping to complete the whole process.
Procured server (Alibaba Cloud/mainstream cloud, ownership belongs to Party A, Kailing only has usage rights), fixed IP filing, and one-stop deployment, launch, and operations.
A graphical and visualized sandbox testing environment, convenient for joint debugging and fast to go live, avoiding repeated re-applications for time-limited sandboxes.
Full source code delivery with copyright transfer, clear ownership; Party A independently controls upgrades and secondary development, balancing flexibility and continuity.
Core members have over 5 years of business-finance-tax experience and Leqi Direct Connection practical cases; deeply integrated with SAP and ERP, supporting customized secondary development, and can be interviewed before signing.
After delivery, dedicated personnel are assigned for specialized O&M, continuously understanding the business and architecture; long-term support for system upgrades, version updates, and tax integration.
