Kailing Technology's individual income tax APP invoice issuance for individuals interface seamlessly integrates with enterprise bidding management systems, enabling compliant full-process data flow

In bidding and tendering business scenarios, compliant settlement of labor remuneration has always been a real challenge for enterprises. Especially after bid evaluation experts, review consultants, and other individuals provide labor services, enterprises need to obtain legally valid invoices as business-finance-tax vouchers, while traditional invoicing processes are complex, lengthy, and have low cooperation, often leading enterprises into the dilemma of "costs without invoices, high tax risks, and low accounting efficiency."

In response to this pain point, Kailing Technology launches an individual income tax app invoice issuance for individuals interface solution. Through secure and compliant connection with the electronic tax bureau system, it achieves full-process automation from labor occurrence, identity authentication, and online invoicing to tax payment. This interface can be seamlessly embedded into enterprises' existing bidding management systems, making labor invoicing no longer a "breakpoint" in the business closed loop, but a compliance hub for the four-flow integration of contract flow, business flow, capital flow, and invoice flow.

I. Core pain points of labor service invoicing scenarios in bidding and tendering

In scenarios such as bidding agency, project review, and expert consulting, enterprises often face the following problems:

- Experts are mostly individuals, with low willingness to issue invoices and a high operational threshold;

- Cumbersome offline invoicing process, time-consuming and labor-intensive, affecting expense settlement efficiency;

- Enterprises find it difficult to track invoicing progress in real time, and low invoice collection rates prevent costs from being listed as compliant expenses;

- Under China Golden Tax Phase IV, the risk of "white slip bookkeeping" becomes prominent, easily triggering tax audits and corporate income tax increases.

II. Seamless integration: making invoicing a natural part of the system

Kailing Technology provides standardized API/SDK interfaces, supporting deep embedded integration with enterprise bidding and tendering management systems. After the system completes the signing of expert service agreements and confirmation of remuneration, it can automatically trigger the invoicing process:

1. Integrated identity authentication: Integrating police identity verification and electronic tax bureau face scan authentication, experts can complete "one face scan, dual verification" within the system, without switching between multiple platforms.

2. Automatic information filling: the system automatically populates key fields such as enterprise information, expert identity, labor remuneration amount, and place of taxable occurrence, reducing manual filling errors.

3. Intelligent tax calculation and payment: Automatically calculates VAT, surcharges, and individual income tax according to the tax policies of the project location, and supports online tax payment via UnionPay, third-party payment, and other methods.

4. Automatic invoice return: After invoice issuance is completed, automatically return to the enterprise system and automatically associate with contracts and payment vouchers, forming a complete business evidence chain.

III. Full-process compliant circulation, truly achieving "four flows consistency"

Through deep interface integration, enterprises can complete the following within the same platform:

- Contract flow: electronic contract signing → archiving of service agreement clauses → automatic linking of business and invoicing;

- Business flow: expert recruitment → service execution → deliverable acceptance → full-process digital evidence preservation;

- Fund flow: remuneration calculation → payment approval → online tax payment → expense settlement → bank transaction records verifiable;

- Invoice flow: automatic invoicing application → tax bureau review → invoice generation → return and archiving → access at any time.

Each invoice corresponds to complete contracts, business, and payment vouchers, completely eliminating the risk of "invoice-business separation" and fully complying with the verification requirements of China Golden Tax Phase IV for business authenticity and consistency.

IV. Solution core advantages

- Minimalist operation: the expert end features full guided operation, supporting voice prompts and graphic assistance, with average invoicing time shortened to within 5 minutes;

- Compliance without worry: strictly follows State Taxation Administration policies and directly connects with the electronic tax bureau to ensure invoices are legally valid;
