1.Comparison of mainstream invoicing methods and selection recommendations  

Depending on enterprise needs and technical capabilities, the current mainstream automated invoicing methods can be divided into the following three types:

Rule- and logic-based "automated robot" technology that completes the invoicing process by connecting to databases or reading files to extract data.  

Pros: Non-intrusive integration, suitable for scenarios such as e-commerce where data platform integration documentation is lacking.  

Disadvantages: Requires plugin installation, low operating efficiency, insufficient stability, and data security risks.  

2. API interface invoicing

Interact with the invoice management system through network communication to achieve real-time transmission and management of invoicing data.  

Pros: No plug-in required, flexible embedding into business modules, low cost, and supports rapid integration.  

Disadvantages: In-house development requires certain investment, but mature third-party services can greatly lower the threshold.  

3. Leqi Interface Invoicing

Through direct connection to the tax authority's standard interfaces, it is efficient, environmentally friendly, and compliant with tax regulations.  

Pros: Free and efficient, suitable for qualified large enterprises.  

Disadvantages:Strict application conditions,Interface modifications and continuous R&D investment are required, forEnterprises andHigh Technical Requirements, most enterprises cannot complete it on their own and also need third-party services to solve it。  


Comprehensive recommendation:  

Prioritize API-based invoicing: balancing cost, efficiency, and stability, especially suitable for SMEs.  

RPA invoicing as the second choice: suitable for flexible but non-high-frequency scenarios.  

Leqi interface invoicing: suitable for large enterprises with sufficient resources and long-term compliance needs.
