Kailing Technology's interface accurately verifies individual identity, excluding legal representatives, supervisors and senior executives, enabling compliant and efficient reverse invoicing and individual invoicing business.

I. A compliance red line that is easily overlooked

Reverse invoicing and invoice issuance for individuals solve the "first invoice" problem when enterprises purchase from individuals or pay for labor services. But not everyone holding an ID card is eligible to participate in such transactions as an "individual."

The tax bureau has clear restrictions on this:Individuals serving as the legal representative, director, supervisor, or senior manager of an enterprise, as well as operators already registered as individual industrial and commercial households, may not enjoy the relevant policies for invoice issuance for individuals or reverse invoicing as ordinary natural persons.

The reason is not hard to understand. These individuals already have business entity status in the business registration system, and their transactions with enterprises may constitute related-party transactions or business operations, which do not fall within the scope of "individuals occasionally providing labor services/selling goods." If an enterprise issues reverse invoices or agency invoices for such individuals without screening, once a tax audit determines that the entity status does not match, the consequences are: invalid invoices, input VAT transfer-out, back taxes plus late fees, and in serious cases, it may be classified as false invoicing.

The problem lies in—How can an enterprise know whether the person opposite is the legal representative or supervisor of a certain company?

Rely on manual verification? A resource recycling enterprise deals with dozens or hundreds of individual sellers every day, and a conference company involves dozens of experts in each event. Checking each one on the National Enterprise Credit Information Publicity System is neither realistic nor reliable. Moreover, a person may hold different roles in multiple enterprises at the same time, with information scattered across business registration databases in different provinces.

II. Technical implementation: three-layer verification, millisecond-level response

In the reverse invoicing system and the individual invoicing system, Kailing Technology has built in an automated identity verification mechanism. When an individual enters the invoicing process, the system automatically completes the following verifications in the background:

First layer: police identity verification

Call the Ministry of Public Security identity authentication interface to compare whether the name and ID number match, confirming a real and valid natural person identity. At the same time, use liveness detection (face scan) to confirm that the operator is the person themselves, preventing invoice issuance under another person's identity.

Second layer: Penetrating query of business registration roles

Based on ID number and business registration information, automatically query whether the natural person holds the following roles nationwide:

Enterprise legal representative

Enterprise shareholders (controlling or actual controllers)

Board members

Supervisory Board members

Senior management (general manager, deputy general manager, finance head, etc.)

Individual business operators

The query covers national business registration data, with no province or enterprise type restrictions.

The third layer: result determination and business interception

Verification results are divided into three handling methods:

Passed: If the individual does not hold any of the above roles, they can proceed normally to the invoicing process

Intercept: If the individual clearly holds the identity of legal representative/supervisor/senior executive/sole proprietor, the system automatically blocks invoicing and returns the specific reason to the enterprise side

Alert: If the individual has historical role records for a deregistered enterprise, the system flags a reminder, and the enterprise decides whether to continue

The entire verification process is automatically triggered after the individual completes face-scan authentication, requiring no additional operation, with response completed in seconds. It is completely seamless for individuals, while adding a solid compliance barrier for enterprises.

III. Application in reverse invoicing scenarios

Taking the resource recycling industry as an example. Enterprises purchase waste paper, scrap steel, and waste plastics from individual sellers and need to issue reverse purchase invoices. According to policy requirements, the target of reverse invoicing must be "individuals regularly engaged in the recycling of scrapped products," and the annual invoicing quota must not exceed 5 million yuan.

The Kailing Technology Reverse Invoicing system embeds identity verification at the delivery appointment stage:

At first registration, the system automatically completes public security verification + penetrating business role query

Each time a delivery note is created, the system verifies in real time the individual's RMB 5 million annual cumulative quota.

Synchronously verify whether it is a director, senior executive, or individual business owner

If any condition is not met, the delivery note cannot be created, blocking non-compliant transactions from entering subsequent processes at the source

This means: non-compliant transaction counterparties simply cannot enter the invoicing process, and companies do not need to remedy things afterward, but complete risk isolation in advance.

IV. Why can't we rely only on manual work or post-event audits?

Some enterprises may think: I'll just have finance staff do spot checks, or handle it at year-end audit. This approach carries extremely high risk under China Golden Tax Phase IV:

Timeliness issue. Business registration information changes frequently, and manual queries can only reflect the status at the time of query, unable to cover the time of invoicing. However, tax audits determine whether the natural person had a compliant identity "at the time of invoicing."

Coverage rate issue. Limited coverage of manual spot checks. For an enterprise issuing tens of thousands of invoices annually, even a 10% spot check means 90% of transactions are left unchecked.

Traceability cost issue. If problems are discovered after the event, the invoice has already been booked, deducted, and filed. Reversing it, transferring out input tax, and correcting the filing affect the whole situation. If large amounts are involved, it may also trigger a special inspection by the tax authority.

Burden of proof issue. Under China Golden Tax Phase IV, enterprises bear the burden of proof for the authenticity and compliance of transactions. "I didn't know he was the legal representative" does not constitute a valid exemption. Systematic pre-verification records are themselves evidence that the enterprise has exercised reasonable care.

V. Seamless integration with the invoicing process

Identity validation is not an independent functional module, but a link deeply embedded in Kailing Technology's overall invoicing process. It works in coordination with the following capabilities:

Real-time verification of the 5 million annual quota: Before each invoice issuance, automatically accumulate the natural person's invoiced amount for the current year, and automatically block once the quota is exceeded

E-Tax Bureau registration status pre-check: Identify in advance natural persons who have not registered with the Electronic Tax Bureau, and guide them to complete registration before entering the invoicing process

Four flows consistent evidence chain archiving: Verification-passed records are automatically archived as compliance evidence, forming a complete chain together with contracts, payment vouchers, and invoices

Enterprise management dashboard real-time display: Personnel who fail verification and the reasons are displayed centrally in the management backend, supporting export and batch processing

Compliance is never a slogan, but concrete actions in every transaction and every step. Identity verification may seem like just a small step in the invoicing process, but it determines whether an enterprise can present complete evidence that "I have fulfilled my reasonable review obligation" when facing a tax inspection.

Kailing Technology has turned this action into an automated, systematized, and seamless capability—enterprises do not need to invest additional manpower, do not need to change existing processes, and only need an invisible protective net added in the invoicing system.
