ENGAGEMENT
Pricing & engagement
We don't publish a rate card — complexity varies too much per project for a made-up number to be fair to either side. Send us your requirements and within 30 minutes you'll have a figure written into the contract.
1Describe the job
Message us the background and goals; attach source files or references for a sharper estimate.
2Quote in 30 min
A fixed total and schedule based on workload × complexity. If it's not a fit, no hard feelings.
3Fixed-price contract
The total goes into the contract; 50% to start. Bank transfer and official invoicing supported.
4Pay on approval
The balance only after you approve. Full source files, plus 7 days of free tweaks.
How do you price a mini-program?
A fixed price by feature list × workload: we write the list together first, then you get a total and schedule within 30 minutes. No increases after signing; showcase/booking and commerce builds lean on proven playbooks so budgets stay predictable.
How long until launch?
About 2 weeks for showcase builds, 4-6 weeks for commerce — provided the confirmed scope doesn't change. Prototyping first is what locks that in.
Do we get the source code?
All source code and documentation is handed over, and the server, domain and WeChat accounts are registered in your name. Take over anytime, with anyone — no lock-in.
