所示范围的服务费以 USD 计价。除非明确包含，税费、广告、软件/API 和第三方费用另计。设置费单列。最终范围及条款在开始前商定。
以下详细范围以英语提供；执行语言在个别报价中商定。
One brand, market and delivery language unless stated otherwise. Caps are work limits, not outcome promises. Client supplies lawful data, access and material rights. Public AI actions and content require agreed review. No rankings, leads, revenue, hiring or third-party approval guarantees.
Contract, payment schedule, cancellation, hour rollover and support SLA require an explicit agreement. Legal, tax, investment and regulated work require the appropriate jurisdiction and an authorised professional role; this fee is not evidence of licensure.
Quote/project. Actual iOS software delivery requires separate discovery/prototype/build SOWs, backend, integrations, device/OS matrix, acceptance and launch responsibilities. Discovery is not a completed app.
Quote/project. for actual Android delivery; device/OS testing, backend and distribution specified, rather than assuming the iOS scope/total is interchangeable.
for a base ASO audit + metadata recommendation for one app, one store, one market/language, three competitor reviews and one revision. Paid acquisition, ongoing testing, new creative production and PR/influencers separately quoted, not included in this base.
for the same bounded Google Play ASO baseline, not combined iOS + Android or ongoing ad execution. Broader campaign quoted.
for one core flow, up to eight screens, clickable design prototype/handoff and two revision rounds, one brand/language. Paid user research/testing and additional flows quoted. No production app included.
Quote/month after code assessment. with included triage/implementation hours, supported platforms and working-hours response terms explicitly capped. Historical remediation, new features, major OS migrations, hosting and 24/7 operations separate.
请说明目标、现有系统和限制，以便制定范围明确的方案。
方案列明平台、页面、后端、集成、测试和发布责任。设计、推广和维护分别报价；商店账号、托管、许可证和广告属于另计的第三方费用。
计划取决于需求、素材、API 权限和审核环节。变更可能影响里程碑；商店审核时长和批准不由我们控制。
根据受众设备数据、市场和所需功能选择。原生与跨平台方案各有取舍，应结合要求评估，而非假定某一种总是更好。
不能。收入取决于产品、使用量及运营成本。支付、隐私和受监管用途需要项目专门审查；开发或商店提交不等于合规认证。
