PRODUCTS

Our Own Products

We don't just take projects — we keep building our own products

Schulte Grid

Focus Training Tool

A focus-training Mini Program based on the classic Schulte Grid method, offering standard 5x5, advanced 6x6, and variant modes like letters and classical poetry, with millisecond timing, rankings, and training history. Suitable for students' attention training and adults' daily brain exercise. Scan and train — no registration required.

Songyun Payroll

Payroll & Hours Management Mini Program

A payroll Mini Program for SMEs and flexible-staffing scenarios: built on WeChat Pay's payroll capability, companies batch-pay salaries directly to employees' WeChat balances. On the employee side, daily hours and income details are logged in sync — whether it was paid, how much, and how it was calculated, all clear at a glance.

WHY US

Three Principles, Written into Every Contract

Two fears haunt software outsourcing: projects that never ship, and teams that vanish after launch. Three principles keep both in check.

About Songyun
1

Tailored Builds

No template shortcuts. Every project is designed around your actual business process — pages, fields, and permissions all fit the way you work.

2

Source Code Delivery

After acceptance, you receive the complete source code and database documentation. You own the system outright — no vendor lock-in.

3

Long-term Maintenance

Launch is not the finish line. We provide a free bug-fix period and optional annual maintenance, with response times measured in hours.

COMPARE

Common Practice vs. Our Practice

No competitors named — just two ways of doing business side by side. Judge for yourself.

Aspect Common Industry Practice The Songyun Way
Requirements Build whatever the client says, quoting and starting before requirements are clear We study your business before talking features, and code only after prototype sign-off — three more days of asking saves three weeks of rework
Pricing Lowball the quote to win the deal, then layer on charges throughout development A feature list with an all-inclusive price written into the contract — no hidden fees; major changes are explained and priced before we act
Honest Advice Say yes to everything the client wants — take the money first We talk you out of features you should not build, and recommend mature solutions when they save you money — we earn what we should, for the long term
How We Build Reskin a template and call it "custom development" Custom builds designed from your business process; standard scenarios get deep redevelopment on mature foundations like CRMEB — never from scratch for the sake of it
Source Code Hold the source code hostage, charging annual "service fees" for access Full source code and database documentation delivered at acceptance — the system is entirely yours, no vendor lock-in
Transparency Hard to reach after signing; reappears only near delivery Weekly progress syncs and staged demos at key milestones — issues raised get fixed as they come, the process is always visible
Acceptance Click around twice, no error, call it delivered Core business flows covered by full test cases, walked through item by item — "what done means" is written down before launch
Documentation No documentation — the next team starts from zero Database schema, API docs, and deployment guides ship with the source code — any team can take over
After-sales Unreachable after launch; charges for fixing a typo Bugs fixed free during the warranty period with response in hours; annual maintenance or pay-per-incident afterwards
Data Safety No backup strategy — a shrug when data is lost Scheduled database backups configured at launch, stored off-site, with recovery drills available
Legacy Systems Refuse systems built by others, or push you to rebuild from scratch Assessment first, then three models — in-place upgrade, partial rebuild, or smooth migration — with costs and trade-offs laid out for you to choose
Training Delivery is the finish line; staff adoption is your problem Launch includes hands-on training and an illustrated manual; interfaces follow frontline habits, core actions within three steps
Promises Guaranteed rankings, guaranteed results — promise anything to close We say no to what cannot be done, and put what we promise into the contract — deals won by bluffing always come due
Business Logic One-off deals, revenue depends on constantly finding new clients Renewals and referrals from existing clients are our main revenue — doing every project right is simply in our own interest
OUR COMMITMENT

「Honest Budget, Honest Work」

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.

No Bait-and-Switch

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 High Price, Low Quality

No line of code ships until it passes internal review and acceptance testing. Anything that fails our own acceptance bar never reaches the client.

Often Beyond Expectations

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.

PROCESS

How We Work

Six steps to launch, each with a clear deliverable

1
Discovery
Call or meet to map out your business process, scope, and priorities.
2
Proposal & Quote
A feature list and schedule with transparent all-inclusive pricing — no hidden fees.
3
Prototype Sign-off
Key pages are prototyped; interaction and visual direction confirmed before coding starts.
4
Development
Weekly progress syncs and staged demos; issues raised are fixed as they come.
5
Testing & Launch
End-to-end testing, data initialization, deployment, and hands-on training.
6
Maintenance & Iteration
Bugs fixed free during the warranty period; new features quoted per iteration.

FAQ

Frequently Asked Questions

The four questions most people ask before working with us

It depends on scope: a brochure website starts in the thousands of RMB, Mini Programs and mid-size management systems typically run tens of thousands, and complex platforms are quoted by feature list. We quote a fixed, all-inclusive price per feature list — no hidden fees after signing.

Three principles written into every contract: tailored builds instead of templates, full source code delivery after acceptance, and long-term maintenance after launch. We do not do "hand over the keys and disappear" work — renewals and referrals from existing clients are our main source of new business.

Yes. We first assess the code quality and data structure of your existing system. If it is healthy, we extend it in place; if structural problems are severe, we present a rebuild plan with a cost comparison — the decision is yours. Redevelopment on mature systems like CRMEB is also part of our daily work.

Absolutely — requirements analysis is part of the service. Call us and we will draw the business process out of you, then produce a feature list and a quote. You are free to take that list and compare elsewhere before deciding.

Yes. Anything goes before prototype sign-off. During development, small adjustments are handled free of charge; for changes that affect the schedule, we explain the impact and cost first and proceed only after your confirmation.

During the free warranty period, come straight to us — response times are measured in hours. After that you can sign annual maintenance or pay per incident. Either way, you will always reach someone.

The all-inclusive price is written into the contract — no hidden fees after signing. Source code is delivered in full at acceptance, so any team can take over even if we part ways. Founded in 2021 and still going strong, we live on renewals from existing clients — disappearing is not a business model.

Absolutely. Discovery, prototype sign-off, staged demos, and launch training all follow a mature remote process with fully documented deliverables. On-site visits are available for clients in Zhengzhou and Henan.
