How can enterprises in the culture and Internet industry implement Leqi sandbox connection technical services?

Complete qualification docking, message adaptation, and sandbox joint debugging for the Leqi interface, and output a solution that can be directly used in the production environment. Business systems can issue invoices by calling standard interfaces; establish a primary-backup dual-channel mechanism, with automatic switching when the primary channel is abnormal, ensuring uninterrupted invoicing business; after issuance, PDF, OFD, and XML layout files are automatically returned and archived, meeting the compliant preservation requirements for original files of fully digitalized e-invoices.

What problems did Huludao Fast Rhythm Technology face before launching Leqi Direct Connection?

Serving a large number of individual users and corporate clients, with dense transaction volumes, small and scattered per-transaction amounts, and invoicing requests that may be initiated at any time; invoicing currently relies on standalone tax control devices and web-based issuance one by one, with multiple tax entities operating independently, and the group level unable to exercise unified control; once the invoicing channel is interrupted, it directly affects collections and customer delivery, and a single-channel solution lacks disaster recovery capability.

Business pain points

Serving a large number of individual users and enterprise customers, with dense transaction volumes and small, scattered per-transaction amounts, invoicing requests may be initiated at any time. Currently invoicing relies on standalone tax control equipment and web-based issuance one by one, with multiple tax entities acting independently and no unified group-level control. Once the invoicing channel is interrupted, it directly affects collections and customer delivery, and a single-channel solution lacks disaster recovery capability
Inconsistent invoicing standards across entities make it difficult for the group to supervise subsidiaries from a tax perspective. The qualification application, message specifications, and integration testing for the Leqi interface are highly specialized; self-integration timelines are uncontrollable, and continuous tracking of tax authority rule changes is required. The State Taxation Administration's promotion of Leqi Direct Connection is the established direction for fully digitalized e-invoices. Early adoption not only improves invoicing quotas and stability but also reserves space for future business expansion

Solutions

Complete qualification docking, message adaptation, and sandbox joint debugging for the Leqi interface, and output a solution that can be directly used in the production environment. Business systems can issue invoices by calling standard interfaces.
Establish a primary-backup dual-channel mechanism, automatically switching when the primary channel is abnormal to ensure invoicing operations are not interrupted
After issuance, the PDF, OFD, and XML format files are automatically returned and archived, meeting the compliance preservation requirements for the original files of fully digitalized e-invoices.
Ultimately achieving unified invoicing and centralized supervision for multiple entities within the group, connecting business-finance-tax integration at the informatization level
At the same time, the operating status of invoicing channels is included in monitoring, so anomalies are discovered in advance rather than remedied afterward
