In-house Leqi development too costly? Kailing Technology's full-process solution saves 60% of investment and launches rapidly

With the in-depth advancement of China Golden Tax Phase IV, enterprises accessing the "Leqi" platform to achieve direct tax-enterprise connection has become an inevitable path for digital upgrading. However, enterprises developing their own Leqi integration solutions face multiple pain points such as high costs, long cycles, and high technical thresholds. Kailing Technology's full-process Leqi solution, with its "pre-packaged interfaces + full source code delivery" model, helps enterprises save more than 60% of investment, quickly achieve system launch, and solve tax digitalization challenges.

I. In-house Leqi: a "technical pit" with high hidden costs

Enterprises building Leqi integration themselves must directly face six core difficulties:

1. Complex process design:Dozens of interfaces for invoice issuance, red reversal, delivery, etc. need to be precisely linked, and reverse processes need to be fully independently designed;

2. Rigorous verification logic: Parameter validation rules need to be developed in-house, and error prompts are vague, resulting in low troubleshooting efficiency;

3. Layout file generation:OFD/PDF format files require independent development, and multi-line detail processing is particularly complex;

4. Multi-invoice type compatibility:Ordinary invoices, special invoices, fully digitalized e-invoices, etc. need to be adapted and developed separately;

5. Sandbox race against time:Full testing must be completed within 72 hours; if failed, the application process restarts;

6. Continuous investment in operations and maintenance:APIs are frequently upgraded with policies, with an average annual iteration cost exceeding RMB 300,000.

II. Kailing Solution: Pre-packaged interfaces break the efficiency dilemma

Kailing Technology achieves a leap in efficiency through three major innovations:

1. Modular encapsulated interface

▪ Prebuilt full-process interface suite for invoice issuance, delivery, red-letter reversal, and more

▪ Embedded automated verification engine for precise error localization

▪ Automatic generation of layout files for multiple invoice types, supporting XML/OFD/PDF multi-format output

2. Full source code delivery for independent controllability

▪ Provide 100% system source code, giving enterprises core control

▪ Supports private deployment, ensuring tax data security

▪ Provides custom development interfaces for flexible integration with business systems such as SAP and Yonyou

3. Leqi experts provide full-process support

▪ Expert TeamCanFull-process on-site support,Help quicklyComplete system deployment

▪ Sandbox testing experience library covers 300+ common issues

▪ Proactive alerts for policy changes, interface upgrades completed within 72 hours

III. An inevitable choice under the wave of tax reform

As fully digitalized e-invoices are comprehensively promoted, enterprises face a dual challenge: they must meet the mandatory requirements for Leqi access while also controlling digital transformation costs. Kailing Technology's practice shows:

▪ Input savings: 60% lower initial investment than self-development

▪ Timeliness improvement: launch cycleFrom several monthsCompressed toDigitalZhou

▪ Controllable risk: 5-year operation and maintenance costs locked in, avoiding policy fluctuation risks

IV. Case confirmation: the common choice of leading enterprises across multiple industries

▪ A rail transit giant: output VAT invoicing originally relied on manual work, with low reconciliation efficiency and tax risks. After connecting to the Kailing solution, within 60 days it achieved automatic matching of mall orders and invoices, online financial review, second-level invoicing, and automatic delivery in three formats (PDF/OFD/XML), improving efficiency by 300%.

▪ A certain new energy group: Its300Yu Tax Number originally used standalone tax control equipment for invoicing. After introducing the Kailing Group Edition output VAT platform, integration with business systems was completed within 90 days, enabling contract-driven invoicing, batch printing and mailing, and full-process tracking.

▪ A certain leading trust company: Due to strong regulatory requirements in the financial industry, it adopted Kailing's fully intranet private deployment solution, efficiently completing direct connection and interoperability with business systems and automatic delivery and archiving of fully digitalized e-invoices while ensuring data security.

Faced with the wave of China Golden Tax Phase IV's "tax governance by data," enterprises urgently need efficient, compliant, and low-cost Leqi access solutions. With full-process closed-loop services and deep industry accumulation, Kailing Technology is becoming the "optimal solution" for more and more enterprises' tax digital transformation, allowing enterprises to save millions in R&D costs, focus on core business, and embrace the future of tax digitalization without worry.
