Difficult to implement Leqi Direct Connection for the public transport industry (highway tolls/urban buses)? Kailing Technology provides reliable and efficient fully digitalized e-invoice Leqi connection solutions

As the fully digitalized e-invoice reform advances, many regions have made clear that the original paper fixed-amount invoices in the public bus and road passenger transport sectors are no longer valid reimbursement vouchers. Coin receipts for urban buses and tickets for road passenger transport must shift from paper fixed-amount tickets to electronic invoices (fully digitalized e-invoices), enabling passenger self-service invoicing, compliant invoicing, and traceable data. For a large urban transportation operating group with multiple segments such as urban buses, road passenger transport, and travel life services, involving hundreds of tax entities, how to uniformly, compliantly, and stably connect the invoicing business of each segment to Leqi is a considerable implementation challenge. Kailing Technology's fully digitalized e-invoice Leqi Direct Connection solution is precisely a group-level solution for such scenarios.

▍1. Fixed-amount invoices discontinued, multiple segments scattered: where is the difficulty in implementing public transport invoicing?

Moving public transportation invoicing onto fully digitalized e-invoices is difficult not just because of "issuing an electronic invoice," but because of a triple overlap:

• Fixed-amount tickets discontinued, passengers want self-service invoicing: After coin-operated or ticket-based rides, passengers need electronic invoices for reimbursement. How can passengers self-service and compliantly issue them on the vehicle and on the ticket.
• Dispersed across multiple sections and multiple entities: Public buses, passenger transport, and travel life belong to different operating units, corresponding to different invoicing accounts and tax numbers; if each sector separately applies for Leqi and builds its own system, it is easy to have inconsistent standards and form data silos.
• Traditional invoicing methods are unstable: Some modules still use the robot (RPA) invoicing mode, requiring daily verification code login, face scan authentication, and manual supervision, with insufficient stability during large invoice volumes and peak periods.

For this reason, the Leqi implementation in the public transportation industry tests not single-point invoicing, but overall solution capability of "group-level unification, self-service, and sufficient stability"—this is also the starting point of Kailing Technology's fully digitalized e-invoice Leqi solution.

▍II. Group unified construction and unified management: one group, one platform

Kailing Technology's fully digitalized e-invoice Leqi Direct Connection solution advocates building a group-level Leqi platform uniformly from the group perspective, bringing invoicing business scattered across various segments under unified management, forming a fully digitalized e-invoice capability foundation of "one group, one platform, unified standards," rather than each segment applying separately and building redundantly.

• Direct connection entity/user entity model: The group, as the direct connection entity, applies for Leqi uniformly, and each operating unit accesses it as a user unit; the group provides unified supervision and consistent standards, while respecting the existing structure, allowing both separation and unification.
• Unified governance, say goodbye to silos: Invoicing data from the public bus, passenger transport, and travel life sectors is uniformly aggregated, allowing the group to view invoicing, view data, and control risks in a unified manner.

▍3. How the three major scenarios are implemented: coin-operated receipts, travel and life, and road passenger transport

A transportation operations group often has multiple business lines such as public buses, passenger transport, and travel-life services at the same time, each with its own invoicing scenarios. Kailing Technology's Fully Digitalized E-Invoice + Leqi solution is implemented separately by scenario while also managed under unified administration:

① Urban/urban-rural buses (coin tickets): scan to issue, about 15 seconds

Bulk pre-printing of QR code tickets of different denominations, with the denomination marked on the ticket (e.g., 1 yuan, 2 yuan, 5 yuan); the passenger inserts the corresponding coins and the driver tears off one ticket of the matching denomination. The passenger scans the code to enter the invoicing portal; the system automatically retrieves the invoicing entity and amount based on the ticket number, and the passenger only needs to fill in the title to issue an electronic invoice, taking about 15 seconds in total, with download or email delivery available. Ticket numbers are pre-imported in the backend with "one ticket, one invoice" status management to prevent duplicate invoicing; for multiple invoicing entities under a group, a unified number segment coding rule is established (invoicing entity identifier + denomination + serial number), and scanning automatically verifies "valid and not yet invoiced", preventing wrong entity or duplicate invoicing at the source.

② Multi-format travel and life scenarios: wherever an order is placed, users can issue invoices without noticing

Covers a multi-business ecosystem including real-time buses, culture and tourism, automotive services, e-commerce, and charging. The goal is that wherever an order is generated, users can directly apply for, view, and download electronic invoices within the travel life App, without any user perception; between the platform and the App, two integration methods are supported: active data retrieval and counterparty data push, flexibly adapting to the existing operations and maintenance setup.

③ Long-distance road / scheduled passenger transport: fixed-amount passenger tickets exchanged for fully digitalized e-invoices

Passenger tickets are converted from paper fixed-value tickets to fully digitalized e-invoices, and passengers can exchange for an e-invoice as soon as they collect the ticket; for existing segments that have adopted robots (RPA) for proxy issuance, Kailing upgrades them to Leqi Direct Connection (API direct invoicing), eliminating daily verification code login and face scanning and other manual authentication, achieving stable 24/7 invoicing, and integrating the passenger transport segment with public transit and travel life into the same group platform with unified standards.

▍IV. Why use Leqi Direct Connection instead of RPA: stable, controllable, never down

The same invoice issuance, but the method used to connect to tax authorities determines whether long-term stable scaling is possible. Kailing Technology's fully digitalized e-invoice Leqi solution provides engineering safeguards in four aspects:

• Leqi Direct Connection replaces RPA: The entire process connects to the electronic tax bureau via Leqi Direct Connection (API), eliminating manual authentication such as daily verification code login and face scanning, achieving stable 7×24 invoicing; RPA is only a transitional measure, while direct connection is the long-term solution.
• Primary channel + fallback dual channel: Two channels run in parallel and back each other up, avoiding invoicing interruptions during the Leqi channel's quarter-end upgrade period and ensuring business continuity.
• Full source code delivery: The source code and intellectual property of the built system are fully delivered to and held by the group, not privatized by the supplier, ensuring compliance and controllability of group assets.
• High-availability deployment: Adopt a high-availability architecture of load balancing + dual active applications + database primary-backup, easily handling high-concurrency invoicing during peak periods.

▍FAQ

Q: If the group has multiple invoicing entities with different tax numbers, could the wrong entity be used for invoicing?

A: No. The system uses unified number segment coding (invoicing entity identifier + denomination + serial number) plus "one invoice per issuance" status management. When scanning, it automatically brings up the corresponding invoicing entity and amount, and verifies validity and that it hasn't been issued, preventing wrong entities or duplicate invoicing at the source.

Q: If the Leqi Direct Connection channel is upgraded at quarter-end, will it cause invoices to be unable to be issued?

A: Kailing uses a primary channel plus fallback dual-channel parallel setup with mutual backup, avoiding invoicing interruptions during channel upgrades so business does not stop.

Q: Why emphasize Leqi Direct Connection instead of continuing to use RPA?

A: RPA requires daily manual authentication and relies on manual monitoring, with insufficient stability under large invoice volumes and peak periods; Leqi Direct Connection uses API integration with the Electronic Tax Bureau, requiring no manual authentication, stable 7×24, suitable for the high-concurrency volume of public transportation.
