引言
电商行业有一句话：售前服务决定转化率，售后服务决定复购率。
用户下单只是交易的开始，真正考验电商平台能力的是售后服务。当用户收到商品后发现质量问题、尺码不合适、或者根本没收到货时，OMS系统如何快速、高效地处理退货、退款、换货、补发等售后请求？
售后管理不仅仅是业务流程的设计，更涉及财务对账、库存回流、物流逆向、客服工单等多个系统的协同。本文将从第一性原理出发，系统性地探讨售后管理的设计与实现。
售后业务全景
售后类型分类
售后业务四大类型：
1. 仅退款（未发货/未收货）
- 场景：订单未发货，用户取消订单
- 流程：审核 → 退款 → 释放库存
2. 退货退款（已收货）
- 场景：商品质量问题、不喜欢、描述不符
- 流程：申请 → 审核 → 退货 → 验货 → 退款 → 入库
3. 换货（同款/异款）
- 场景：尺码不合适、颜色不喜欢
- 流程：申请 → 审核 → 退货 → 验货 → 发新货
4. 补发（未收到货/少货）
- 场景：物流丢件、发货少件
- 流程：申请 → 核实 → 补发
