How much does a website / mini program / app cost?

Price follows scope, not page count. Typical ranges: brochure corporate sites ¥3,000–12,000 CNY (~$420–1,700); marketing sites with forms, CMS and multilingual support ¥8,000–30,000 (~$1,100–4,200); WeChat mini programs from ¥8,000 (~$1,100); two-platform apps and business systems from ¥30,000 (~$4,200). After a scope call you get a written quote itemized per feature, stating exactly what is and isn't included — no mid-project surprises.

Can I get a proposal before deciding to hire you?

Yes. Send your business context, the problem to solve, reference products and a rough budget, and I will return a free initial proposal: feature list, tech stack, timeline and price range. No fee, no lock-in — you are welcome to compare it with other vendors.

What are the payment terms?

Usually 30/40/30 by milestone: 30% after proposal and prototype sign-off, 40% when development reaches acceptance, 30% after launch and source code handover. Small projects can be 50/50. Every milestone has visible deliverables — no 100% upfront payments.

Who owns the source code, domain and servers? What exactly is delivered?

You own everything. Deliverables: complete front-end and back-end source code, database schema, deployment docs, an account inventory, design source files (when applicable) and one assisted deployment. Domains, servers, store and developer accounts are registered under your entity — I never hold them. After handover any team can take over.

What happens after launch? Is there maintenance?

The first year after launch is a free bug-fix period — functional defects are fixed anytime. Afterwards, optional monthly maintenance covers updates, security patches, backups and small features; you can also walk away with your source code and self-maintain. Production issues are triaged by severity, usually with a same-day response.
