Kailing Technology Invoice Issuance for Individuals Interface Integration: enabling one-stop automated processing of bidding and tendering expert remuneration settlement and invoice issuance

Against the backdrop of comprehensively advancing digital tax supervision, China Golden Tax Phase IV takes "data-driven tax control" as its core, driving enterprise tax management toward full traceability and intelligent early warning. Especially for bidding enterprises that cooperate with a large number of individuals such as external experts, lecturers, and consultants, how to efficiently complete remuneration settlement and invoice management under the premise of compliance has become an important challenge in financial management. Under the traditional method, enterprises need to repeatedly coordinate with individuals to complete identity authentication, invoice application, material submission, and tax payment. The process is cumbersome, the cycle is long, communication costs are high, and tax risks are easily triggered by information errors or omissions.

In response to the above pain points, Kailing Technology has launched an invoice issuance for individuals API interface integration solution for bidding and tendering scenarios, dedicated to achieving full-process automation from identity verification and intelligent tax calculation to online invoicing and individual income tax withholding, helping enterprises build a compliant, efficient, and transparent business-finance-tax management system for external collaboration.

I. Main pain points currently faced by enterprises

1. High Tax Compliance Risk

   - China Golden Tax Phase IV strengthens the "four flows in one" supervision, and enterprises must retain a complete business evidence chain (contracts, payment vouchers, service records, invoices). If compliant invoices cannot be obtained in a timely manner, it may trigger system warnings and even lead to tax supplements and fines.

   - Tax bureaus in different regions have different requirements for invoice issuance for individuals, and policy implementation standards vary, so enterprises face compliance adaptation challenges when issuing invoices across regions.

2. Invoicing process is cumbersome, with high communication costs  

   - Individuals usually lack business-finance-tax knowledge and operational experience, and enterprises spend significant time and effort guiding them through real-name verification, face-scan login, and filling in invoicing information.

   - Manual processing is prone to information entry errors, improper item selection, and inaccurate tax rate application, resulting in unusable invoices and affecting booking and payment.

3. Difficult to verify business authenticity and retain materials

   - Enterprises are responsible for business authenticity, but under traditional models it is difficult to verify service results in real time and retain electronic evidence, easily creating false invoicing risks.

   - Lack of a systematic archiving mechanism makes it difficult to quickly retrieve a complete set of business materials during tax audits.

4. Cross-regional invoicing and tax filing are complex

   - Experts are distributed across the country, and enterprises need to issue invoices according to the place where the business occurs and adapt to different regional individual income tax withholding rates, making manual calculation error-prone and resulting in a high invoice return rate.

   - The individual income tax withholding process is scattered, requiring finance staff to switch between multiple platforms, resulting in a heavy workload and easy omissions.
