How can expert fees in the bidding and tendering industry be invoiced? Kailing Technology helps platforms integrate tax interfaces, allowing experts to self-issue invoices via mobile APP

In the daily operations of the bidding and tendering industry, the settlement of bid evaluation expert service fees and invoice issuance have long been difficulties and pain points in industry development. With the official implementation of the VAT Law on January 1, 2026, combined with the rigid enforcement requirements of the Individual Income Tax Law of the People's Republic of China and the Invoice Administration Measures of the People's Republic of China, local competent authorities have also successively issued detailed rules. For example, the Shaanxi Provincial Development and Reform Commission explicitly requires that bid evaluation expert service remuneration must be taxed in accordance with the law and provided with VAT invoices. Compliant invoicing of expert fees has become an unavoidable mandatory requirement for bidding platforms and related enterprises. Kailing Technology has launched a dedicated invoicing solution for expert fees in the bidding and tendering industry. By deeply integrating tax compliance interfaces with bidding platforms, bid evaluation experts no longer need to travel to offline tax bureaus and can complete self-service invoicing through a mobile APP alone, fundamentally solving the industry's invoicing challenge.

I. The invoicing dilemma for bidding and tendering expert fees is prominent; compliance transformation brooks no delay

Settlement of expert fees in the bidding and tendering industry, due to characteristics such as dispersed participants, cross-regional business, and specialized operational processes, has created multiple industry pain points in the invoice issuance stage. Under the regulatory background of China Golden Tax Phase IV's "tax governance by data," these problems continue to escalate corporate compliance pressure.

1. Tightening policy supervision, with risks of booking without invoices stacking layer upon layer

China Golden Tax Phase IV has achieved penetrating management of the verification of business authenticity and invoice compliance. The "white slip accounting" method is no longer recognized by tax authorities at all. If bidding enterprises cannot obtain compliant invoices corresponding to expert fees, they will not only face corporate income tax adjustments, tax supplements, and late fees, but may also receive administrative penalties in tax audits, directly affecting their tax credit rating.

2. High operational threshold for experts, generally low cooperation with invoicing

Bid evaluation and review experts are mostly senior professionals in various industries, with high time costs and unfamiliarity with the professional operations of tax invoicing. Under the traditional invoicing model, experts need to bring their ID cards and various documents to offline tax bureau queues, with the entire process averaging 2-3 hours. The cumbersome operations make experts extremely unwilling to cooperate, also resulting in a general invoice collection rate of less than 50% for enterprise expert fee invoices.

3. Large cross-regional policy differences, manual processing prone to compliance loopholes

Bidding and tendering business often spans provinces and cities nationwide, and tax authorities in different regions differ in the scope, tax rate standards, and documentation requirements for invoice issuance for individuals. Corporate finance staff find it difficult to accurately grasp the policy details of all regions. In the manual process of coordinating invoice issuance, problems such as incorrect tax rate application and missing document submissions easily arise, further intensifying corporate tax compliance risks.

4. High enterprise management costs, and it is difficult to retain the full-process evidence chain

Under the traditional model, enterprises need to assign dedicated staff to contact experts one by one to collect information, assist with invoicing operations, and organize and archive invoices, generating high labor and time costs. At the same time, data and information in links such as expert fee contract signing, fund payment, invoice issuance, and service confirmation are scattered, making it difficult to form a complete business evidence chain of "four-flow consistency." Enterprises remain passive when responding to tax audits.

II. Kailing Technology's customized business-finance-tax solution solves the full-chain invoicing challenges of bidding expert fees

In response to the industry characteristics and core pain points of expert fee invoicing in the bidding industry, Kailing Technology creates an exclusive customized solution, deeply integrating the compliant interface of the National Unified Standard Electronic Tax Bureau with bidding platforms, building a full-process digital invoicing system of "platform + mobile end," achieving full online closed-loop operations from expert identity authentication to final invoice delivery, enabling all invoicing participants to operate efficiently.

1. Deep integration of tax interfaces builds a solid foundation for platform compliance

Kailing Technology strictly follows national tax laws and regulations and the connection standards of the Electronic Tax Bureau, achieving secure and efficient data interaction between bidding platforms and the tax system through compliant technical interfaces. Without redirecting to the official tax bureau website or APP, the bidding platform can directly complete core operations such as invoice application submission, real-time synchronization of review status, and automatic tax calculation, ensuring every step of the invoicing process is compliant and traceable, fully meeting China Golden Tax Phase IV's verification requirements for business authenticity and building a solid compliance foundation for platform invoicing operations.

2.Expert-side operations extremely simplified, self-service invoicing easily completed on mobile

To adapt to experts' usage habits and operational capabilities, Kailing Technology has streamlined the complex tax invoicing process. Experts do not need to download tax bureau-related apps; they can complete the entire self-service invoicing process simply through the mobile end (APP/mini-program/H5) linked to the bidding platform, with simple and easy-to-understand steps:

- One-tap registration and authentication, zero-threshold operation: supports two registration and authentication methods—facial recognition and UnionPay bank card recognition—with no complex information filling required. After completing real-name authentication at first registration, subsequent logins require no repeated authentication; in Beijing, face-scan-free operation is even implemented, greatly lowering the threshold for expert operation;

- Automatic information pre-filling, reducing manual operations: The bidding platform automatically synchronizes basic information such as the expert's name, ID number, and contact information, as well as business information such as bid evaluation project name, expert fee amount, and business location, to the invoicing system. Experts only need to confirm the information is correct and submit the application, without manual entry one by one;

- Intelligent tax calculation and payment, flexible payment methods: the system automatically and accurately calculates various taxes and fees such as VAT, urban maintenance and construction tax, education surcharges, and individual income tax based on invoicing amounts and business locations, supports both WeChat and Alipay QR code payment and unified enterprise payment on behalf, and synchronizes tax payment results to the tax system in real time, making payment status clear at a glance;

- One-click invoice acquisition enables efficient and convenient transmission: tax authorities can complete invoicing review within 10-60 minutes on working days. After approval, electronic invoices and tax payment certificates are automatically generated. Experts can download and save them directly on mobile, and enterprises receive invoice information simultaneously, eliminating offline mailing and enabling efficient invoice transmission.

3.Integrated enterprise-side control: full-process invoicing visualization and traceability

Bidding and tendering platforms can directly connect to the enterprise-level dedicated management dashboard built by Kailing Technology, enabling integrated, visualized control of the entire expert fee invoicing process, making corporate finance and operations management more efficient:

- Real-time viewing of invoicing progress, review status, and tax payment status for all experts on the platform, supporting one-click retrieval of invoice information by expert name, project name, invoicing time, and other dimensions for more efficient management;

- The system automatically associates and integrates expert fee contracts, fund payment vouchers, bid evaluation service confirmation records, and invoice information to form a complete business evidence chain of "four-flow consistency." All data is stored in a structured manner and can be accessed with one click during tax audits, eliminating manual organization;

- Supports generating invoicing statistical reports by dimensions such as bidding projects, business regions, and time periods, automatically summarizing core data such as invoicing amount, tax amount, and invoice receipt rate, providing precise data support for corporate financial accounting, cost control, and business decisions.

4.Full online red-letter reversal tax refunds, considerate protection throughout the invoice lifecycle

If an invoice needs red-letter reversal due to special circumstances such as incorrect invoice information entry or cancellation of a bidding project, experts can directly initiate an invoice red-letter reversal application via mobile, and the system will automatically connect to the Electronic Tax Bureau to complete the entire red-letter invoice issuance process. After the red-letter reversal is completed, the invoice tax is generally refunded to the original route within T+1 according to the payment path, subject to local tax authority regulations. The entire red-letter reversal and refund process requires no offline visits by experts or enterprises to tax authorities, providing considerate protection throughout the invoice lifecycle and making subsequent issue handling more convenient.

III. Backed by multi-dimensional innovation advantages, reshaping the invoicing service experience for bidding expert fees

Kailing Technology's expert fee invoicing solution for the bidding and tendering industry is not a simple tax interface connection, but full-process optimization and innovation combined with industry characteristics. Through multi-dimensional core advantages, it completely reshapes the service experience of expert fee invoicing in the bidding and tendering industry, achieving a win-win-win for experts, enterprises and platforms.

1. Extremely simplified operation, greatly improving expert cooperation

Transform the professional and complex tax invoicing process into mobile operations familiar to experts, creating a fully guided operation interface with voice prompts and graphic assistance. The entire invoicing process can be completed within 5 minutes, thoroughly solving the core problem of experts "not knowing how to issue and unwilling to issue," and expert cooperation can be increased to over 95%.

2. Intelligent policy adaptation, no compliance blind spots in cross-regional invoicing

The system has built-in a policy database for bidding and tendering expert fee invoicing across all provinces and cities nationwide, and can automatically match local tax rate standards, invoicing scope, and operational requirements based on the place where the business occurs. No matter where experts come from or which region a bidding project is distributed in, compliant invoicing can be achieved, fundamentally avoiding tax compliance loopholes caused by policy misinterpretation.

3. Information encryption protection for comprehensive privacy and security

Strictly comply with the Personal Information Protection Law and other relevant regulations, encrypting the storage and transmission of sensitive information such as experts' ID numbers, bank card numbers, and contact information, while implementing tiered permission management on the enterprise side. All operational behaviors retain complete logs, ensuring information is accessed only by authorized personnel as needed, comprehensively safeguarding experts' personal information security and enterprises' business data security.

4. Business-finance-tax integration, helping enterprises reduce costs and increase efficiency

Completely replace the traditional manual coordination and offline invoice-running model, helping enterprises greatly reduce the labor input of finance and operations personnel, with labor costs reduced by more than 70%. The invoice collection rate for expert fees can increase from less than 50% to more than 98%, and the overall settlement cycle for expert fees can be greatly shortened from 30 days to within 3 days, enabling enterprises to achieve comprehensive improvement in operational efficiency while achieving business-finance-tax compliance.

IV. Policy Alignment + Value Delivery: A Preferred Business-Finance-Tax Compliance Solution for the Bidding and Tendering Industry

The expert fee invoicing solution for the bidding and tendering industry built by Kailing Technology fully conforms to national tax policies and the implementation rules of local competent authorities. The VAT invoices issued are all formal and compliant documents recognized by tax authorities and can be directly used as pre-tax deduction vouchers for corporate income tax, avoiding from the source the risks of enterprise tax adjustment increases, tax supplements, and late payment penalties, giving enterprises solid policy support for business-finance-tax compliance.

In actual implementation applications, this solution has helped numerous bidding platforms and related enterprises achieve compliant and digital transformation of expert fee invoicing: after a national bidding platform adopted it, the expert fee invoice collection rate increased from 42% to 96%, saving more than 2 million yuan in annual tax risk costs.
