How can enterprises in the finance · professional services industry implement a fully digitalized e-invoice input-output management platform?

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 existed before China Credit Trust launched Leqi Direct Connection?

Service fees are charged to customers by project or period, with the charging basis tied to contract terms, and invoicing needs raised separately at each project milestone; currently, invoicing relies on standalone tax control devices and web-based issuance one by one; multiple tax entities operate independently, and the group level cannot exercise unified control; once the invoicing channel is interrupted, it directly affects collection and customer delivery, and a single-channel solution lacks disaster recovery capability.

Enterprise overview

China Credit Trust Co., Ltd. was founded in 1995, formerly China Coal Trust. In 2008, with State Council approval, the Ministry of Finance transferred its state-owned equity to the People's Insurance Company of China Group, which became the company's largest shareholder. The company is the first chairman unit of the China Trustee Association and a member unit of the Securities Association of China and the China Government Bond Association. In 2001, it became one of the first trust and investment companies approved for re-registration. Since then, it has successively obtained enterprise annuity fund legal person qualification, special purpose trust trustee qualification, overseas wealth management business entrustment qualification, and qualification to engage in equity investment business with proprietary assets, making it one of the trust companies in China with relatively complete business qualifications.

Business pain points

Service fees are charged to customers by project or period, with the charging basis tied to contract terms, and invoicing needs raised separately at each project milestone. Currently, invoicing relies on standalone tax control devices and web-based issuance one by one; multiple tax entities operate independently, and the group level cannot exercise unified control. Once the invoicing channel is interrupted, it directly affects collection 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
