What is the problem?
给中文新手的一份海外收款手续费估算草稿：先拆出平台费、换汇、提现、退款、税务和时间成本，再用保守情景表判断项目报价是否还能覆盖交付风险。
Quick solution
Treat this as a Upwork tutorial issue. First confirm the environment, inputs, permissions, logs, and delivery boundary. Then use the linked deep guide for the full checklist before changing production code or promising a result.
Read the deep guideDetailed steps
- 确认订单来源：自由职业平台、独立发票、数字产品平台、订阅工具还是客户公司采购系统。
- 记录客户付款币种、你希望入账的币种，以及是否会发生换汇。
- 列出平台层费用：平台佣金、交易处理费、订阅费、提现门槛、退款和争议处理规则。
- 列出银行和收款账户层费用：提现费、入账费、汇率差、到账时间、账户冻结或审核条件。
- 做三种情景：客户付款成功、客户退款、客户延迟付款。每种都写下你能保留多少证据。
- 用保守汇率和偏高成本估算净收入，不要把最理想情况当作报价基础。
