Avoid Detours in Leqi Connection! Kailing Technology Fully Digitalized Leqi Solution Full-Process Guidance

Against the backdrop of the comprehensive promotion of fully digitalized e-invoices under China Golden Tax Phase IV, the Leqi platform, as the core carrier for direct connection between the tax system and enterprises' own information systems, has become a key lever for enterprises to achieve business-finance-tax digital transformation. However, problems such as cumbersome Leqi access processes, high technical thresholds, and significant compliance risks deter many enterprises. Kailing Technology's full-process Leqi solution, from application preparation to system implementation and then to operations and maintenance assurance, escorts enterprises throughout the process for efficient access and fewer detours.

I. Leqi awareness first: understand the core value and access key points

Through direct connection between the tax system and enterprises' own information systems, the Leqi Platform provides eligible enterprises with standardized and open fully digitalized e-invoices and other tax-related services, achieving integrated "business, finance, and tax" convergence.

- Compared with traditional invoicing models, Leqi has significant advantages:Supports offline invoicing to avoid peak-time lag, replaces facial recognition authentication with a fixed IP to achieve 365×24 uninterrupted invoicing, and can alsoCan succeedas a commercial advantage for large bidding and tendering projects, while responding to national policy direction to bring implicit benefits.

- Enterprises connecting to Leqi need to clarify the core prerequisites:The direct connection entity must meet basic conditions such as tax credit A/B, revenue and invoice volume standards, and possess comprehensive technical security capabilities; user entities must have an association relationship with the direct connection entity and meet corresponding tax credit requirements. In addition, after access, service management specifications such as matter changes, version updates, and qualification renewal must be strictly followed to ensure long-term compliant use.

II. Facing access pain points head-on: analyzing the core difficulties of Leqi Direct Connection

Enterprises independently connecting to Leqi face multiple challenges, and a single misstep can delay the go-live schedule:

- Complex process design:Must self-develop the connection logic between the proprietary business system and the Leqi interface. Reverse process design is highly difficult, and incorrect interface call order directly leads to invoicing failure;

- Cumbersome verification logic:Passing invoicing data parameters requires extensive development of adaptation and validation rules; the interface only returns success or failure, with no specific error reason, and business-level validation risks must be borne by the enterprise itself;

- Layout file processing:After invoice issuance, PDF/OFD/XML layout files must be synthesized independently, custom style development is highly difficult, and the tax bureau template has limited extensibility;

- Difficulty adapting to multiple invoice types:The validation logic, layout design, and process parameter passing differ significantly for different invoice types, requiring repeated sorting and development;

- Strict sandbox testing:All activation capability tests must be completed within 72 hours; if failed, the application must be resubmitted and await review;

- Operation interface development:Must independently build an operation interface including permission management, invoicing approval, statistical analysis, and other functions, which places high demands on the development team.

III. Kailing full-process solution: end-to-end support from application to operations
