Beijing enterprise fully digitalized e-invoice Leqi Direct Connection: Kailing Technology uses full-scenario automation solutions to reshape the enterprise invoicing experience and business-finance-tax competitiveness

With the comprehensive and in-depth advancement of China Golden Tax Phase IV, Beijing—this benchmark city leading China's digital economy development—is taking the lead in entering the deep-water zone of "tax governance by data." Fully digitalized e-invoices are no longer a future trend, but a present reality that enterprises must embrace for compliant operations. The "Leqi" natural tax collection and administration system direct connection model strongly promoted by the State Taxation Administration has opened up a highway for seamless data flow across "business, finance, and tax" for enterprises. However, for many enterprises in Beijing, especially group enterprises with diversified businesses, complex structures, and huge invoicing volumes, the "entrance ramp" of this highway—Leqi Direct Connection access—is full of technical thorns and compliance pitfalls.

Faced with the many obstacles of self-developed integration, Beijing Kailing Technology Co., Ltd., with its precise grasp of the capital's policy context and deep technical accumulation, launches the "one-stop Leqi Direct Connection and automated invoicing solution," aiming to provide Beijing enterprises with a professional, efficient, and reliable path for digital leapfrogging.

I. The dilemma of in-house development: dissecting the six practical difficulties of Leqi Direct Connection, an unbearable burden for enterprises

If an enterprise chooses to explore Leqi Direct Connection alone, it is like sailing alone in unknown waters and will inevitably face a series of severe challenges:

1. The "logic maze" of business processes:Leqi only provides basic API interface capabilities, and enterprises need to build complete forward and reverse business flows such as invoicing, red-letter reversal, and voiding from scratch. Any error in the sequence of interface calls or delay in status synchronization may cause the entire invoicing process to fail, just like a carefully designed domino chain that stalls completely because one piece is placed improperly.

2. "Silent verification" and the "isolated assumption" of risk:The return values of the Leqi interface are often only "success" or "failure", like a silent examiner. When invoicing fails, whether it is due to a tax rate mismatch, an incorrect commodity code, or incorrect buyer information, the enterprise must invest substantial development resources in log analysis and logic troubleshooting. More critically, the Leqi platform does not validate business logic risks related to transaction authenticity and invoice compliance; these risks are borne entirely by the enterprise.

3. The "last step" gap from data to paper invoices:After successful issuance, Leqi returns only structured XML data. What is needed for legal validity and customer delivery is a neatly formatted PDF or OFD file. How to precisely synthesize multi-line details, complex tables, and specific seals into format files compliant with national standards is an independent development project requiring deep technical accumulation.

4. The pain of "reinventing the wheel" with numerous invoice types:VAT ordinary invoices, special invoices, fully digitalized e-invoices, motor vehicle invoices... Different invoice types have completely different field rules, validation logic, and format templates. Each time a new invoice type is integrated, almost all of the above development work must be redone, and development costs grow exponentially.

5. "Sandbox stress testing" racing against time:The sandbox testing environment opened by the Leqi Platform requires enterprises to complete joint debugging and testing of all interface functions within 72 hours after capability activation. This is an extreme test of the development team's response speed, testing completeness, and troubleshooting ability. Once the time limit is exceeded or the test is not passed, the entire application process must start over, consuming time and effort.

6. The ongoing "long march of operations and maintenance" and "shackles of compliance":The direct connection entity is responsible for the tax-related data security of all user entities on the platform and needs to continuously follow up on Leqi interface upgrades and policy changes. This means enterprises must not only establish a normalized high-level technical operation and maintenance team but also always stay vigilant about data security and tax compliance, resulting in enormous management costs and psychological pressure.

II. The key to breaking through: Kailing Technology's panoramic output VAT invoice automation solution, letting data drive business value

In response to the above pain points, Kailing Technology deeply understands the unique needs and policy environment of local enterprises in the wave of the digital economy, and has created a scenario-driven, deeply integrated, and independently controllable Leqi automatic invoicing solution. We not only open up interfaces, but are also committed to opening up the vital channels of enterprise value creation.

Scenario 1: Full-chain connectivity, keeping contracts, invoices, and funds in sync

From the moment front-end sales personnel complete contract approval in CRM, an invoicing application is automatically generated and circulated. After finance personnel conduct compliance review on a unified platform, one click triggers the system to directly connect to Leqi Direct Connection and issue fully digitalized e-invoices in seconds. Invoices are automatically pushed to customers via SMS, email, and WeChat, and the status is synchronized back to the business system in real time, automatically triggering the collection process. Payment collection information can in turn write off invoice status. This is not only invoicing automation, but also the construction of an intelligent business closed loop of "invoicing upon business occurrence, collection upon invoicing, and write-off upon payment collection," significantly accelerating capital recovery and putting Beijing enterprises' demand for "efficiency first" into practice.

Scenario 2: Seamless connection with complex business formats, intelligent order processing engine

Faced with massive sales data from various ERP systems such as SAP, Oracle, Yonyou, and Kingdee, or OA systems such as Weaver and DingTalk, our solution acts like an intelligent "central nervous system." It can not only stably obtain data through multiple methods (API, intermediate tables, files), but also has a built-in powerful intelligent order processing engine. Whether it is "automatic splitting of mixed tax rates" for hardware sales combined with technical services, "batch shipment and batch invoicing" for large equipment procurement, or "monthly service consolidated invoicing" for logistics customers, the system can automatically and accurately complete order merging, splitting, and discount calculations according to preset rules, meeting invoicing needs under complex businesses such as group enterprises, retail giants, and high-tech manufacturing enterprises, completely freeing finance personnel from cumbersome manual judgment and manual operations.

Scenario 3: Empowering the new economy, a "zero-perception" e-commerce invoicing experience

For e-commerce platforms and new retail brands in Beijing, the invoicing experience directly affects customer satisfaction and repurchase rates. Our solution can be deeply embedded in self-operated malls and mini-programs or connected to mainstream e-commerce platforms. When consumers place orders and pay, invoice information is synchronized in real time; after order completion, invoices can be issued automatically or triggered by customers with one click and delivered instantly. During major promotions such as "618" and "Double 11," the system can calmly handle order peaks, achieving instantaneous and accurate issuance of massive invoices, completely eliminating manual entry and long waits, greatly improving customer experience and safeguarding enterprise reputation.

Scenario 4: Online-offline integration, creating the ultimate invoicing touchpoint

In offline scenarios such as physical stores, exhibitions, and service sites, we provide dual capabilities of "scan-to-invoice instantly" and "convenient manual invoicing." Staff can generate an invoicing QR code with a tap, and customers complete it by scanning the code and filling in the header, with an experience comparable to scan-to-pay. For special invoicing needs, finance personnel can easily fill in information through a highly visualized and friendly interface, just like editing a document, with the system previewing the layout in real time, achieving "what you see is what you get." This ensures that enterprises do not lose business flexibility while pursuing automation efficiency, comprehensively covering various business scenarios.
