Henan Songyun Intelligent Technology Co., Ltd. is a software company based in Zhengzhou, Henan, China, specializing in custom software development and digital solutions. Our services cover corporate websites and web applications, WeChat Mini Programs, Android/iOS/HarmonyOS app development, custom industry management systems, software-hardware integration, and SEO & GEO search optimization. As a CRMEB service partner, we also deliver CRMEB-based mall implementation and deep redevelopment. Built around a PHP (ThinkPHP) and Vue full-stack core, we work on three principles — tailored builds, full source code delivery, and long-term maintenance — serving clients across Henan and throughout China, from requirements analysis and legacy redevelopment to custom development, launch, and ongoing operations.
We are not in the business of "hand over the keys and disappear". Management systems are used every single day — post-launch responsiveness matters far more than pretty promises during development. That is what "long-term maintenance" means to us.
From websites to systems, from projects to products.
Founded in Zhengzhou, starting with corporate websites and WeChat platform development.
Delivered our first software-hardware integration project, extending into BLE device communication and IoT data ingestion.
Entered logistics and healthcare: the container depot system and dental marketing system went live.
Formed a three-track service system (custom systems + Mini Programs + websites); launched our own product Schulte Grid.
The universal billing system and drone weather system landed; became a CRMEB service partner as mall implementation and redevelopment work grew; client industries passed 20.
Launched GEO and app development service lines (including HarmonyOS); Songyun Payroll went live; the bilingual website launched.
Not verbal promises — hard constraints written into our process
Key modules are reviewed by two engineers. Naming, layering, and exception handling follow unified standards — no "only one person understands it" code.
Database schema, API docs, and deployment guides ship with the source code, so any team can take over later.
Core business flows are covered by full test cases, walked through item by item at acceptance — not just "clicked twice and no error".
Full protection against SQL injection, XSS, and unauthorized access; payment projects follow WeChat Pay platform security specs.
Scheduled database backups are configured at launch, stored off-site, with recovery drills available.
Every quote is broken down by feature — every dollar maps to a concrete deliverable. And on that basis, we habitually do a little more: the final result usually exceeds what the client expected.
What we quote is what we deliver — the same solution, the same effort. When we build on a mature open-source base like CRMEB, we charge redevelopment rates, never repackaged as "built from scratch" at a premium.
No line of code ships until it passes internal review and acceptance testing. Anything that fails our own acceptance bar never reaches the client.
The feature list is the floor, not the ceiling. We habitually think one step ahead on performance, security, and detail — and usually deliver a little more than you expected.
Ten years, deep service across 100 industries
