Three differences of the Leqi Platform & Leqi connection difficulties

Published: 2024-03-14 16:56

Leqi—is a platform through which the State Taxation Administration provides eligible enterprises, via direct connection between the tax system and the enterprise's own information system, with tax-related services such as fully digitalized electronic invoices under open rules and unified standards.

So what is the difference between Leqi Direct Connection and online invoicing on the fully digitalized e-invoice platform? What is the difference in management between the two platforms? During the enterprise's application for Leqi, the integrationofDifficultiesYesWhich ones... let's take a look together~


01 The difference between Leqi's open rules and the openness of the tax control system


Leqi rules openness

Tax control system opening

Enterprises issue invoices in their own systems, and invoice data is generated by their own systems.
Unclear rights and responsibilities: Legal rights and responsibilities among taxpayers, tax control hosting parties, and platform service providers are unclear.
After an enterprise issues an invoice, invoice delivery can be achieved without going through the tax bureau system.
Data risks: Enterprise tax-related data flows and is stored with third parties, posing information leakage risks.
Invoice data is automatically uploaded, providing only interfaces for data upload, clearing, and download.
Tax doubt: A large number of invoices are issued based on the same MAC or IP address, generating tax doubt data
Return to the essence of commercial transactions by embedding invoice rules into the enterprise's own systems, so transactions can be invoiced independently and on demand.
Issuance dependency: invoices carry too much tax information, and issuance depends on the tax bureau.

04 The six major difficulties of Leqi integration

Difficulty One Frequent API updates, high system design difficulty, and high operating costs

Currently, Leqi has 17 capabilities and over 100 interfaces, with complex content and high update frequency. Enterprises need to spend a lot of time and effort understanding the Leqi Access Guide and coordinating R&D to implement requirements, which is costly and difficult. At the same time, faced with frequent system upgrades, enterprise IT teams need to complete system modifications and testing in sync; if updates are not timely, business operations will be affected.

Difficulty Two Difficult management of invoice pre-coding, difficult stable invoicing during business peak periods

For most group enterprises, multiple group formats, large business volume, and high concurrent invoicing volume are the norm. Therefore, the system's invoice pre-assignment code management design is required to be excellent, with functions such as pre-assignment code download, automatic download when remaining pre-assignment codes fall below a threshold, pre-assignment code allocation, segmented use, and high-concurrency multi-threaded invoicing.

Difficulty Three "Tax-control + fully digitalized" shared credit limit; improper management affects business

During the paper-electronic parallel transition period, the fully digitalized e-invoice quota may be insufficient due to occupation by tax-controlled invoices, making it impossible to issue invoices. Therefore, it is necessary to conduct comprehensive and real-time monitoring and management of data for all invoicing scenarios during the transition period to avoid affecting business development.

Difficulty Four Tax-enterprise direct connection, large data carrying capacity, high information security requirements

Whether for tax bureaus or enterprises, the confidentiality of business-finance-tax data is of paramount importance. Leqi pilot units transmit invoice data through direct-connection unit IP plus symmetric key encryption. Once the key is leaked, it will cause a major data security incident, so extremely secure information encryption methods are required.

Difficulty Five Invoicing success rate is unstable, affecting customer inquiries

Unlike electronic invoice platforms, the invoicing logic of the Leqi open platform is "issue first, transmit later": first assign codes offline, then obtain business data, calculate tax amount, and generate invoices locally. When the invoice is delivered to the customer, it has not yet been uploaded to the tax bureau. During peak periods, bandwidth congestion and upload failures will result in problematic invoices that customers cannot find at the tax bureau, causing disputes and customer complaints.

Difficulty Six Fully digitalized e-invoice red-letter reversal business is complex and has a major impact on the original business logic

Unlike the paper invoice era, red-letter reversal of fully digitalized e-invoices is a two-way right. For blue-letter invoices that have been booked or whose use has been confirmed, both the seller and buyer can initiate an application, and after the other party confirms, the reversal can be completed. When designing the system, special attention must be paid to real-time reminder functions for such red-letter reversal business to strictly control invoice risks.

Common Questions
What is the difference between Leqi Direct Connection and online invoicing on the fully digitalized e-invoice platform?
Leqi Direct Connection invoicing: rules embedded in the system, enabling batch generation and offline invoicing, with efficiency of more than one invoice per second. Fully digitalized platform invoicing: requires logging into the electronic tax bureau and scanning a code for authentication, manual entry, efficiency ≤5 seconds, supports fully digitalized paper invoices, and verification and authentication are charged per invoice/year.
What difficulties do enterprises face in connecting to the Leqi platform?
Six Major Difficulties: frequent interface updates and high operating costs; difficult invoice pre-coding management and difficult stable invoicing during peak periods; tax control + fully digitalized shared credit limit, improper management affecting business; large data volume in tax-enterprise direct connection and high information security requirements; unstable invoicing success rate and easy disputes in customer inquiries; complex red-letter reversal business for fully digitalized e-invoices, requiring real-time reminders to prevent risks.
What is the difference between the Leqi Platform and tax control system opening?
Leqi rules openness: invoices are generated by the enterprise's own system, data is automatically uploaded, no third party is needed, rights and responsibilities are clear, returning to the essence of transactions. Tax control system openness: unclear rights and responsibilities (taxpayer, hosting party, service provider), data stored with a third party carries leakage risks, a large number of invoices sharing the same MAC/IP easily raises tax red flags, and invoicing depends on the tax authority.
What is the management difference between the Leqi Platform and the fully digitalized platform?
Leqi: fixed IP + TOKEN login, no authentication required, files generated locally for delivery, download code segments assembled, supports fully digitalized e-invoices, no verification or authentication fees.
