Say goodbye to integration challenges: Kailing Technology helps you unlock the technical upgrades required for Leqi services

Against the backdrop of China Golden Tax Phase IV and the full popularization of fully digitalized e-invoices, "Leqi Services," as the core vehicle for tax-enterprise direct connection, is becoming a key lever for large and medium-sized enterprises to achieve business-finance-tax digital transformation. Simply put, Leqi Services is a "tax-enterprise direct connection platform" provided by the State Taxation Administration for eligible enterprises—enterprises only need to build a fully digitalized e-invoice digital platform and connect to the tax bureau's electronic invoice service platform through SDK engines, API services, database tables, and other technical means to achieve a full-process closed loop of direct invoicing, intelligent reimbursement, and automatic accounting. However, in transitioning from the "traditional invoicing model" to the "Leqi Direct Connection model," enterprises need to break through a series of technical barriers, and Kailing Technology's fully digitalized e-invoice Leqi solution provides a one-stop path to solve these problems.

I. The technical "roadblocks" for enterprises connecting to Leqi: six core difficulties to break through

Whether it is invoicing management on the output side or invoice processing on the input side, when enterprises build their own Leqi self-use platform, they often fall into multi-dimensional technical difficulties, and these difficulties also become the key constraints on upgrade progress.。

(1) Output side: process reconstruction from "decentralized invoicing" to "centralized control"

1. Business process reengineering:The invoicing trigger must be moved forward from "manual initiation by finance" to "automatic push by business systems." For example, after a sales order is completed, the system automatically synchronizes invoicing information to the Leqi platform. This requires enterprises to connect the data flow between business systems and Leqi interfaces。

2. Full-chain compliance control:Before invoice issuance, prerequisite operations such as taxpayer risk inquiry, available tax rate verification, and tax classification code matching must be completed. The absence of any step or an incorrect sequence will cause invoicing failure。

3. Reverse process design:Red-letter invoice issuance involves multiple steps such as red-letter confirmation form application, query, confirmation, and cancellation, requiring enterprises to develop their own logic judgment modules.

(II) Input Side: Data Breakthrough from "Manual Processing" to "Automated Closed Loop"

1. Multi-channel invoice collection:It is necessary to support multiple scenarios such as automatic synchronization of fully digitalized e-invoices (XML/OFD/PDF), scanning and recognition of paper invoices, and invoice collection from email/WeChat card packs, and ensure the completeness and accuracy of collected data。

2. Intelligent review and exception control:Abnormal invoice detection algorithms must be developed (such as identifying voided invoices, out-of-control invoices, and invoices from blacklisted sellers), while also achieving automatic write-off matching between invoices and purchase orders and warehouse receipts。

3. Automated certification and deduction:Must directly connect to the tax bureau's deduction platform to achieve batch selection, certification statistics, and tax amount calculation of input VAT invoices, avoiding the risk of missed or erroneous deductions caused by manual operations.

(3) Common technical barriers of Leqi Direct Connection

Besides the specific difficulties of output VAT invoices and input VAT invoices, enterprises connecting to the native Leqi interface also face six common challenges：

II. Kailing Technology Solutions: one-stop solution to Leqi technical upgrade challenges

In response to the technical pain points of enterprises integrating with Leqi, Kailing Technology, based on a Xinchuang foundation plus mature products plus full-process services, has created a fully digitalized e-invoice Leqi solution, helping enterprises skip the trial-and-error stage of going from 0 to 1 and directly achieve technological upgrade and implementation across the three dimensions of output VAT invoice, input VAT invoice, and direct connection integration.

(1) Output side: compliant, intelligent, and automated centralized invoicing system

1. No code development required throughout the entire process:Preset business system integration templates eliminate the need for enterprises to write interfaces themselves. After a sales order is completed, it is automatically synchronized to the invoicing platform, and the system automatically completes pre-operations such as taxpayer information verification, tax rate matching, and pre-assigned code acquisition. Invoicing is just one click away;

2. Intelligent drive for reverse processes:Built-in red-ink invoice processing logic, automatically determining the buyer's deduction status—if already deducted, the system automatically reminds the business to contact the buyer to initiate red-ink reversal; if not deducted, automatically completes the red-ink confirmation form application and invoicing, with no manual intervention;

3. Multi-dimensional visualized control:Provides group-level invoicing statistical reports, displaying in real time each subsidiary's invoicing volume, credit limit usage, and proportion of abnormal invoices, and supporting filtering and analysis by business line, customer type, and invoice type, achieving a closed loop of "invoicing-control-analysis."

(II) Input Side: Invoice Management Platform with Full Lifecycle Digitalization

1. Omni-channel collection and intelligent recognition:Supports automatic synchronization of fully digitalized e-invoices, OCR recognition of paper invoices (accuracy above 99%), and automatic collection of WeChat/email invoices. After collection, authenticity verification, duplicate checking, and compliance validation (such as seller tax credit rating and blacklist verification) are automatically completed;

2. Automated write-off and posting:Through preset matching rules, invoices are automatically written off against purchase orders and goods receipt notes; after write-off approval, payable vouchers are automatically generated and directly connected to the financial system, with no manual entry required;

3. Secure archiving and convenient retrieval:According to the requirements of the Ministry of Finance and the State Taxation Administration, automatically retain the XML original of fully digitalized e-invoices, enabling linked archiving of invoices and accounting vouchers, and supporting quick retrieval by invoice number, date, and buyer name, avoiding the storage and retrieval difficulties of paper archiving.

(3) Difficulties of Leqi Direct Connection: KailingOne-stopStyle cracking

- Process linkage:The system has built-in the full-process logic of Leqi, so enterprises only need to configure parameters to achieve full-chain connectivity from "business-Leqi-finance";

- Verification logic:Preset 100+Item red invoice rules, 50+Item blue invoice rules; when the interface returns an error, the system automatically prompts the specific reason;

- Layout files:Self-developed layout composition technology, supporting custom invoice templates and automatically generating PDF/OFD/XML formats to meet customer delivery and internal archiving needs;

- Sandbox testing:Provides a visual testing platform, supporting single-capability testing and full-process simulation, equipped with dedicated technical consultants to assist in completing testing within 72 hours, with a 100% pass rate;

- Operation Interface:Provides a simple and easy-to-use front-end interface covering all scenarios including invoice issuance, approval, statistics, delivery, and red-letter reversal, and supports group permission management.
