Five-Flow Integration full-chain evidence preservation | Kailing Technology builds a new digital and secure solution for reverse invoicing in resource recycling

With the official implementation of the State Taxation Administration's "reverse invoicing" policy in 2024, the renewable resource recycling industry has reached a key juncture in its business-finance-tax compliance transformation. The policy clarifies the invoicing obligations between individual sellers and resource recycling enterprises, the tax and fee withholding process, and evidence chain retention requirements, and also sets higher standards for enterprises' digital capabilities.

Against this background, based on a deep understanding of policy logic and a comprehensive review of renewable resource recycling business scenarios, Kailing Technology has launched a "reverse invoicing digital management solution" for resource recycling enterprises. With "five flows in one" as its core, the solution builds a closed-loop management system of business flow, invoice flow, fund flow, contract flow, and logistics flow, and combines it with a full-chain evidence preservation mechanism to create a digital security foundation that meets regulatory requirements and is traceable and verifiable.

I. Industry Transformation Under Policy Drivers: From "Passive Compliance" to "Proactive Governance"

Announcement No. 4 of 2024 of the State Taxation Administration clarifies the operational path and compliance requirements for resource recycling enterprises to "reverse invoice" natural person sellers. The policy not only specifies the prepayment and filing procedures for VAT and individual income tax, but also emphasizes that supporting materials such as purchase contracts, weighbridge tickets, transport vouchers and payment records must be kept for tax inspection.

This means companies can no longer maintain operations by relying on "supplementary invoicing after the fact" or "vague vouchers," but must complete the generation, collection, and preservation of evidence at the same time the business occurs. Based on this policy direction, Kailing Technology has built a digital system covering the entire chain of "before transaction, during transaction, and after transaction," helping companies improve efficiency while achieving compliance.

II. Five-Flow Integration: building a closed-loop trusted business data chain

Kailing Technology's reverse invoicing solution takes "five-flow integration" as its core design concept, ensuring every transaction forms a complete, traceable data loop in the system:

- Contract flow:Supports online signing of legal documents such as purchase contracts and authorization letters, with automatic archiving by the system for subsequent verification.

- Business flow:From order generation and weighbridge ticket entry to transaction completion, the system records business progress throughout, ensuring data is authentic and real-time.

- Logistics:Integrate with the weighbridge system and transportation vouchers to record cargo weight, transportation routes, and other information, forming a complete logistics evidence chain.

- Invoice flow:Through connecting with the Baiwang invoicing system, realize automated processing of reverse invoicing, supporting operations such as tax item matching, quota verification, and red-letter reversal.

- Capital flow:The system connects with the payment platform, recording the fund flow of each transaction to ensure invoice-payment consistency.

These five types of data are automatically aggregated and cross-verified in the system, forming a tamper-proof business evidence chain that meets all tax regulatory requirements for "proving business authenticity."

III. Full-chain evidence preservation: making every transaction verifiable

In reverse invoicing business scenarios, the authenticity and completeness of the evidence chain are the core of compliance. Kailing Technology's system is built around the concept of "full-chain evidence preservation," constructing a complete closed loop from business occurrence to evidence archiving, ensuring that every transaction is verifiable and traceable to its source.

1. Automatic collection of evidence across the entire business process

Through deep integration with enterprise peripheral systems (such as weighbridge systems, fund systems, SAP, etc.), the system achieves automatic collection and synchronization of business data:

- Automatic connection of orders and weighbridge tickets:When recyclables enter the recycling station, the weighbridge system automatically generates weighing records. The system obtains key data such as weight, time, and vehicle information in real time and associates them with orders, forming the starting point of the business.

- Online contract signing and authorization:After individuals complete real-name authentication through the WeChat mini program, they can electronically sign purchase contracts and authorization letters online; the system automatically archives the electronic version of the contract and records traceability information such as signing time and IP address.

- Automatic matching of payment receipts:After the fund system completes the transfer, the system automatically captures the payment receipt and binds it to the corresponding business, ensuring the fund flow direction is clear and verifiable.

- Transport voucher collection:For businesses requiring transportation, the system connects to the logistics platform, automatically obtains transport documents and route trajectories, forming a complete logistics evidence chain.

2. Full lifecycle management of suppliers and customers

To ensure the authenticity of transaction entities, the system has built-in comprehensive supplier and customer management modules:

- Natural person registration and real-name authentication:Recycling enterprises invite individuals into a mini-program via a dedicated QR code, where they submit ID card and bank card information and complete face recognition real-name authentication, ensuring the seller's identity is authentic and valid.

- Supplier review and maintenance:Enterprises can maintain basic supplier information, logistics addresses, and historical transaction records in the backend, and support tiered supplier management, with key tracking of individuals involved in high-frequency and large-value transactions.

- Customer information management:The system supports maintaining basic data, receiving addresses, invoicing requirements, etc. of downstream factories, achieving complete link management from recycling to sales.

3. Structured archiving and management of evidence preservation materials

All collected evidence materials are structured and archived by business dimension in the system, forming a "one order, one file" electronic dossier:

- Input VAT invoice pool management:Reverse-issued invoices automatically enter the enterprise input VAT invoice pool. The system calculates and prepays taxes based on sales amount and records the business document corresponding to each invoice, achieving full association of invoice, payment, goods, and contract.

- One-click export of evidence chain:When facing a tax audit, enterprises can quickly filter in the system by time period, business type, and natural person dimension, and export with one click a complete evidence package including contracts, weighbridge tickets, payment records, transport vouchers, and invoices, greatly improving response efficiency.

- Long-term archiving and compliant retention for inspection:The system supports long-term storage of evidence materials and can set retention periods according to policy requirements, with reminders to archive or clear upon expiration, ensuring compliance without omissions.

4. Pre-invoicing compliance verification and risk blocking

The system sets multiple verification rules before reverse invoicing to prevent tax risks from the source:

- Individual quota verification:The system queries in real time the individual's cumulative sales amount since the beginning of the year and the cumulative sales amount within 12 months; if it exceeds 5 million yuan, invoicing is automatically blocked, with a prompt that business entity registration is required.

- Automatic tax category matching:Based on the mapping relationship between product SKUs and tax codes, the system automatically matches the applicable tax items and tax rates to prevent wrong or missed invoicing.

- Evidence completeness check:When initiating an invoicing application, the system automatically checks whether the required evidence for that business (such as contracts and weighbridge tickets) has been uploaded. If missing, it prompts for supplementary upload, ensuring the evidence chain is complete at the time of invoicing.

5. Traceable handling of red-letter reversal and business adjustments

When situations such as returns or price adjustments occur, the system supports designating a blue invoice for full or partial red-letter reversal. The red-letter reversal operation also generates evidence records and is linked to the original business, ensuring that every adjustment is traceable and avoiding tax risks.

The implementation of the reverse invoicing policy is both a challenge and an opportunity for the industry to move toward standardization.
