 ## 前端尾款凭证上传按钮条件（简化了）
 
 ```js
-// 尾款凭证上传按钮
+// 尾款凭证上传按钮：定金模式 + 尾款未付 + 允许的状态
 const showBalanceProofBtn =
-  order.status === 'PENDING_BALANCE'
-  || (order.status === 'PENDING_DEPARTURE' && order.paymentType === 'DEPOSIT' && !order.balanceProofUrl);
+  order.paymentType === 'DEPOSIT'
+  && !order.balanceProofUrl
+  && ['PENDING_BALANCE', 'PENDING_DEPARTURE', 'TRAVELLING'].includes(order.status);
 ```
 
 | 条件 | 说明 |
 |------|------|
 | `status === 'PENDING_BALANCE'` | **主条件**：定金模式清单确认后自动进入此状态，等待上传凭证 |
-| `status === 'PENDING_DEPARTURE' && paymentType === 'DEPOSIT' && !balanceProofUrl` | **补传**：已到待出行但凭证为空，允许补传 |
+| `status === 'PENDING_DEPARTURE'` | 已到待出行但凭证未传，允许补传 |
+| `status === 'TRAVELLING'` | 已在出行中但凭证未传，允许补传 |
 
 ### 不再需要判断 `processStatus === 'READY'`
