Kailing Technology API verifies in one click that a natural person is not a director, supervisor, or senior manager, enabling worry-free compliance for reverse invoicing and invoice issuance for individuals

Published: 2026-04-13 17:40

In scenarios where enterprises conduct business with natural persons, carry out reverse invoicing, or receive invoices issued on behalf of individuals, identity compliance is the first gate of business-finance-tax risk control. Once invoices are mistakenly issued to non-compliant entities such as directors, supervisors, and senior executives (senior management), legal representatives, and individual industrial and commercial households, enterprises may face tax risks, related-party transaction concerns, or even compliance penalties. Traditional manual verification methods are time-consuming, limited in coverage, and prone to omissions. How to quickly and accurately complete identity compliance verification before a transaction occurs has become an urgent need for many enterprises.

To this end, Kailing Technology has launchedIndividual identity compliance verification API, relying on the official data source of the electronic tax bureau, automatically intercepting non-compliant identities and eliminating risks for enterprises from the very first second.


I. Core Mechanism: Authoritative Data + Real-Time Verification 

The core of this solution isThrough the individual's own authorization, it connects to the electronic tax bureau system in real time and automatically identifies their identity attributes。The specific process is as follows:

Authorized login: Natural person users enter their Electronic Tax Bureau username and password on the enterprise's business interface (such as the invoice application page), authorizing the system to query their registration information in real time.

Automatic query: Through an encrypted channel, the system obtains in real time the identity type registered by the individual in the tax system, including whether they belong toLegal representative, directors and senior executives, individual business ownersetc.

Real-time Interception: The system automatically determines whether the natural person is eligible for invoicing based on preset rules (e.g., prohibiting reverse invoicing to incumbent directors and senior executives). If the identity is non-compliant, the process is immediately blocked with the specific reason indicated.

Core mechanism: authoritative data + real-time verification

II. Core advantages of the solution 

Authoritative and accurate, compliant with evidence

Data comes directly from the electronic tax bureau, truly reflecting the registered identity of individuals, avoiding lag or deviation caused by third-party data, and ensuring the verification results have a tax compliance basis.

One-click integration, real-time response

Provides standardized API interfaces that can be quickly embedded into enterprise expense control, reimbursement, payment, or invoicing systems, automatically invoked in verification scenarios to achieve "verify upon submission," seamlessly completing risk control interception.

Prevent risks from the source

Intercept in real time at the front end of the transaction or at the invoicing application stage, preventing non-compliant business from entering subsequent processes and reducing the cost and risk of after-the-fact remediation for enterprises.

Smooth experience, clear user authorization

Individuals themselves independently provide tax account authorization for inquiry, making the process transparent and compliant; the inquiry is only for identity verification and does not touch sensitive personal tax-related data, safeguarding user privacy and information security.

Solution core advantages

III. Application scenario examples 

Enterprises purchase from individuals and use reverse invoicing: Before invoicing, verify whether the natural person is a director, supervisor or senior executive of the entity, to eliminate invoicing for illegal related-party transactions.

Receive invoice issuance for individuals: During reimbursement or payment, verify whether the invoicer is an individual industrial and commercial household (invoices should be issued in the name of that household), ensuring the invoice entity is compliant.

Pre-verification before labor remuneration payment: Before paying labor service fees to a natural person, confirm that their identity is not the legal representative or senior executive of the enterprise, to avoid hidden employment risks.

Kailing Technology's identity compliance verification API is not just a tool, but an important cornerstone for enterprises to build a full-process tax risk control system covering "pre-event, in-event, and post-event." By moving compliance verification nodes forward, enterprises can significantly reduce manual review burdens and improve business process efficiency, while establishing a solid compliance "firewall" in the context of increasingly precise tax regulation.
