客户常见问答 (FAQ)

问：做一个微信小程序要多少钱？ (How much does it cost to develop a WeChat Mini Program?)
答：展示型一般1万–3万；含登录、支付、列表、后台的业务型3万–8万；多角色、营销、消息、数据看板类8万–20万。低于8000元还承诺“全功能”的，大概率是模板套壳。 A display-only Mini Program usually costs ¥10,000–30,000; a business version with login, payment, lists and an admin panel costs ¥30,000–80,000; solutions with multiple roles, marketing, messaging and dashboards cost ¥80,000–200,000. A “full-featured” offer below ¥8,000 is likely a template shell.
问：微信小程序开发多久可以上线？ (How long does it take to launch a WeChat Mini Program?)
答：小程序参考工期2–5周起，业务型MVP常见4–8周，复杂平台2–4个月。具体包括需求梳理3–7天、原型和UI、开发、联调测试、上线部署，确认需求后评估更准。 A Mini Program generally takes 2–5 weeks or longer; a business MVP commonly takes 4–8 weeks, while complex platforms take 2–4 months. The process includes 3–7 days of requirements review, prototypes, UI, development, testing and deployment; a confirmed scope gives a more accurate estimate.
问：uni-app一套代码能同时做小程序和APP吗？ (Can uni-app use one codebase for both a Mini Program and an app?)
答：可以，uni-app或Flutter适合跨端复用，能省40%–50%重复开发成本。但涉及强动画、蓝牙、硬件能力时仍需原生适配，我们会先判断哪些功能适合跨端。 Yes. uni-app or Flutter is suitable for cross-platform reuse and can reduce duplicated development costs by 40%–50%. However, heavy animation, Bluetooth and hardware capabilities may still require native adaptation. We first assess which features are suitable for cross-platform development.
问：小程序上线每年还要交什么费用？ (What annual fees are required after a Mini Program goes live?)
答：微信小程序认证300元/年；服务器、域名、SSL证书、短信按服务商实际价格另计。建议这些账号都用客户自己的实名注册，避免后续资产不在自己手里。 WeChat Mini Program certification costs ¥300 per year. Servers, domains, SSL certificates and SMS are charged separately by the relevant providers. We recommend registering these accounts under your own real name so the assets remain under your control.
问：小程序做完源码归谁？ (Who owns the source code after the Mini Program is completed?)
答：验收结清后，前后端、数据库脚本、接口文档、部署文档等源码100%归客户，并写进合同。上线后30天内免费修非新增需求类Bug，之后可按月续约技术护航。 After acceptance and full payment, 100% of the source code—including frontend, backend, database scripts, API documents and deployment documents—belongs to the client, and this is written into the contract. Bugs not caused by new requirements are fixed free for 30 days after launch; monthly technical support can then be renewed.
问：只做小程序前端，还是后端和管理后台也能一起负责？ (Do you also build the backend API and admin dashboard for the Mini-Program?)
答：我提供完整全栈服务，可同时完成小程序前端、管理后台、后端接口、数据库设计、微信支付配置与服务器部署，无需你再单独找后端开发。 Yes. I handle the entire stack—Mini-Program frontend, web admin dashboard, backend APIs, database, WeChat Pay integration, and cloud deployment.
问：后续要扩展 App 或其他平台小程序，代码能复用吗？ (Can the codebase be reused if we expand to iOS/Android apps later?)
答：可以。若初期就有多端计划，我会采用 uni-app 架构设计；已上线项目也可平滑扩展，将后端 API 与核心业务组件直接复用到 H5 与 App。 Yes. Using uni-app and a unified RESTful API backend, your business logic and UI components can scale smoothly to H5 and iOS/Android apps.
