How can enterprises in the transportation and logistics industry implement the Leqi output VAT fully digitalized e-invoice platform?

Provide an integrated "Leqi Direct Connection + output VAT fully digitalized e-invoice platform + WeChat Mini Program" solution: design a high-availability architecture with a 12-node application cluster + 2-node Oracle database read-write separation, smoothing instantaneous access peaks through load balancing, with a single node stably handling 90,000 visits; the lane software only undergoes lightweight modification, switching the original paper ticket printing interface to an invoicing QR code generation interface without changing toll collectors' existing habits; drivers and passengers scan the code to jump to the "Ji e Xing" WeChat Mini Program, bind their license plate, and filter un-invoiced transaction records by date, supporting single-select/multi-select batch submission for invoicing. Invoicing information is automatically completed by the output VAT fully digitalized e-invoice platform calling the Leqi interface, and PDF/OFD/XML are automatically returned to the Mini Program for download.

What problems existed before Hebei Expressway launched Leqi Direct Connection?

Huge invoicing volume and high system load: annual transaction volume of 170 million, daily invoicing peak of up to 470,000 invoices, and the existing single-node system faces overload and downtime risks under instantaneous high concurrency (e.g., 260,000 visits during morning peak); business data and invoice data are disconnected, finance must repeatedly process data between the provincial center business system and the invoicing system, and invoiced data cannot be automatically returned to the business middle platform; the SMS/email delivery cost for 170 million invoices is high, and drivers and passengers lack a convenient channel to obtain e-invoices, while the paper ticket model cannot meet green environmental protection and traffic efficiency requirements.

How long was the implementation cycle of Hebei Expressway's Leqi Direct Connection project, and what were the results after launch?

Implementation cycle: about Dec 2024 sandbox testing—Feb 2025 province-wide launch. Leqi sandbox testing was completed in December 2024, the WeChat mini-program was piloted in January 2025, and the province-wide official launch ran stably in February 2025; the system overload and downtime problem was resolved, achieving full lifecycle automation of order management, automatic issuance, automatic delivery, and electronic archiving.

Enterprise overview

Hebei Ruitong Expressway Network Operation Co., Ltd. is the core entity of expressway toll management in Hebei Province, responsible for the clearing, operation, and information technology services of the province's expressway network toll collection. As Hebei Province fully promotes the electronicization of toll invoices, it needs to handle an average annual manual lane transaction volume of 170 million and undertake the unified issuance of fully digitalized e-invoices for mixed lane (MTC) tolls across the province's expressways. The current IT setup is a transaction data middle platform deployed on a pure intranet at the provincial center, with front-end lane management software uploading transaction data via dedicated lines and relying on lane ticket printers to automatically print paper invoices.

Business pain points

Huge invoicing volume and high system load pressure: average annual transaction volume of 170 million, daily invoicing peak up to 470,000 invoices, and the existing single-node system faces overload and downtime risks under instantaneous high concurrency (such as 260,000 visits during morning peak)
Business data and invoice data are disconnected, and finance must repeatedly process data between the provincial center business system and the invoicing system, and invoiced data cannot be automatically returned to the business middle platform
1.7 The SMS/email delivery cost for 170 million invoices is high, and drivers and passengers lack a convenient channel to obtain e-invoices; the paper invoice model cannot meet green environmental protection and traffic efficiency requirements
