Kailing Technology and Hubei Changfeng Tongxing launch fully digitalized e-invoice automatic invoicing system for used-car purchase scenario
Kailing Technology and Hubei Changfeng Tongxing launch fully digitalized e-invoice automatic invoicing system for used-car purchase scenario

When purchasing a used car, the business side records not only vehicle information but also the transaction parties, purchase agreement and transaction amount. If invoicing still requires repeated entry in another system, invoices and the original transaction easily become disconnected. Recently, Kailing Technology and Hubei Changfeng Tongxing launched a fully digitalized e-invoice automatic invoicing system, connecting invoicing requests in the business system to the cloud invoice management platform, so that fully digitalized e-invoice issuance, result return and subsequent delivery unfold along the same transaction, filling in a key business-finance-tax digitalization link for the used-car purchase scenario.
I. Hubei Changfeng Tongxing: vehicle services require more complete invoicing capabilities
Hubei Changfeng Tongxing Information Technology Co., Ltd. is deeply engaged in traffic management convenience services and smart vehicle networking, providing digital services for smart transportation and vehicle networking applications. As vehicle services continue to move online, whether transaction information, service processes and invoice processing connect smoothly directly affects the business handling experience and the clarity of subsequent financial reconciliation.
Used car purchasing is a typical scenario. Vehicle information, transaction subjects, and purchase materials are first formed on the business side, while the invoicing action is often completed by another role. Information already in the business system needs to be transmitted again and entered again; after invoicing is completed, the invoice number and files must be backfilled into the original business record. Each additional manual transcription adds another checking step and increases the possibility of information inconsistency.
This collaboration between Kailing Technology and Hubei Changfeng Tongxing embeds invoicing capabilities into the digital chain of vehicle business. Changfeng Tongxing contributes its understanding of traffic management and automotive service scenarios, while Kailing Technology provides the cloud fully digitalized e-invoice platform and implementation integration capabilities, enabling business systems serving used-car circulation enterprises to take on business-finance-tax steps more naturally.

II. Purchase stage: match vehicle transaction materials with invoicing information
The difficulty of used car purchase invoicing lies in the fact that information must correspond to the same real transaction. The seller, vehicle, purchase agreement, transaction amount, and invoicing entity each have their own record locations; once the business side and invoicing side are separated, finance needs to repeatedly confirm with people, and problems such as incorrect invoice fields, hard-to-track invoicing progress, and lack of original basis for subsequent adjustments will also arise.
For used-car circulation enterprises, invoicing compliance is first built on verification of business materials. Vehicle and transaction materials are confirmed by relevant positions according to business rules, and the invoicing system then takes over the confirmed business data and links the issuance result back to the original transaction. In this way, finance staff see not just an invoice but can also find the acquisition business and processing status corresponding to that invoice.
When business volume increases or multiple operating entities are involved, relying on manual forwarding of materials makes it harder to maintain a unified standard. This system launch connects "business initiation - invoice issuance - result return" into a continuous path, providing a clearer processing sequence for the purchase stage and leaving clear clues for subsequent invoice verification, reconciliation and material retrieval.

III. Automatic invoicing: initiated by the business system, returned after the fully digitalized e-invoice is issued
The project adopts the cloud subscription service of Kailing Technology's Ling Shui Tong invoice management platform, with the cloud platform handling output VAT invoice management, and the business system completes integration with the platform. Business personnel proceed with the acquisition process in the original system; after business information meeting invoicing conditions forms a request, it enters the invoicing platform; the issuance results of fully digitalized e-invoices and related invoices are then returned to the business system, reducing cross-system duplicate entry and manual backfilling.
This approach makes the invoicing action follow the business. Vehicle transaction records, invoicing requests and invoice results share the same queryable business thread; business staff can view processing progress, and finance staff can review the invoice around the original transaction. For individual businesses requiring manual handling, the platform also provides manual entry, batch Excel import and scan-code invoicing, balancing automation with on-site business flexibility.
Kailing Technology conducts integration testing, user testing and deployment implementation around system integration, and provides pre-launch training and trial operation support. The business chain is verified item by item in real usage scenarios, so that automatic invoicing can both connect to existing processes and be easy for frontline positions to operate according to established responsibilities.

IV. Invoice Delivery: Red-Letter Processing and Document Return Linked to Business
When a used car transaction changes and the invoice face needs adjustment, subsequent processing also needs to find the original business and original invoice. The Lingshuitong platform supports red-letter issuance of fully digitalized e-invoices and returns both positive and negative fully digitalized e-invoices to the business system after download, so that adjustment records can be linked to the original transaction. Finance can check the invoice status accordingly, and business personnel can also view the processing result along the original business.
Invoices after issuance support automatic delivery in OFD, XML, and PDF formats. Invoice documents are returned together with business records, reducing manual downloading, forwarding, and searching one by one; during financial reconciliation or material retrieval, it is also easier to locate related invoices from acquisition records. Multiple delivery formats serve the different usage needs of enterprises and downstream recipients.
The cloud subscription model keeps invoicing capabilities running continuously through standardized services, while authorized tax IDs and account permissions define clear usage boundaries for different business entities. Kailing Technology integrates invoice issuance, red-letter (credit note) processing, and document delivery into a single service chain, providing a more coherent invoice management experience for vehicle circulation businesses.

V. Value Delivered: Aligning Used-Car Acquisition Business with Business-Finance-Tax Processing in One Chain
After the system went live, Hubei Changfeng Tongxing's vehicle business services gained connectable fully digitalized invoicing capabilities. For the used-car circulation enterprises it serves, acquisition information no longer needs to be repeatedly moved between the business side and the invoicing side, and invoicing results return to the original business record. Business and finance can communicate around the same transaction, reducing the management trouble of "the invoice was issued but the corresponding vehicle or materials cannot be found."
More importantly, the invoicing chain becomes traceable: the front end has the purchase business basis, the middle has invoice issuance and adjustment records, and the back end has deliverable invoice files. Transaction material verification remains the responsibility of the relevant positions; the system is responsible for sending confirmed information into the invoicing process and saving processing results. This division of labor helps enterprises improve processing continuity while maintaining business authenticity and the responsibility boundaries of invoice management.
With mature tax products, business system integration and go-live service capabilities, Kailing Technology supports Hubei Changfeng Tongxing in extending digital capabilities to the used-car purchase invoicing scenario. The cooperation connects vehicle business with fully digitalized e-invoice management into a complete path, providing more solid system support for business collaboration, financial reconciliation and compliant operations of used-car circulation enterprises.
