为什么外贸企业必须搭建专属管理系统？破解获客、履约、风控痛点的底层方案

// 订单管理核心类示例
public class OrderManagementService
{
    private readonly IOrderRepository _orderRepository;
    private readonly ICustomerService _customerService;
    
    public OrderManagementService(IOrderRepository orderRepository, 
                                  ICustomerService customerService)
    {
        _orderRepository = orderRepository;
        _customerService = customerService;
    }
    
    // 创建新订单并验证客户信用
    public async Task CreateOrderAsync(Order order)
    {
        // 检查客户信用状况
        var creditStatus = await _customerService
            .CheckCreditAsync(order.CustomerId);
            
        if (creditStatus.IsApproved)
        {
            return await _orderRepository.AddAsync(order);
        }
        else
        {
            throw new CreditException("客户信用不足，订单创建失败");
        }
    }
    
    // 更新订单状态
    public async Task UpdateOrderStatusAsync(int orderId, OrderStatus status)
    {
        var order = await _orderRepository.GetByIdAsync(orderId);
        order.Status = status;
        order.LastUpdated = DateTime.UtcNow;
        
        await _orderRepository.UpdateAsync(order);
    }
}

-- 订单跟踪查询示例
SELECT 
    o.OrderId,
    o.OrderNumber,
    c.CustomerName,
    o.OrderDate,
    os.StatusName AS CurrentStatus,
    p.ProductName,
    oi.Quantity,
    oi.UnitPrice,
    (oi.Quantity * oi.UnitPrice) AS TotalAmount
FROM Orders o
    INNER JOIN Customers c ON o.CustomerId = c.CustomerId
    INNER JOIN OrderStatuses os ON o.StatusId = os.StatusId
    INNER JOIN OrderItems oi ON o.OrderId = oi.OrderId
    INNER JOIN Products p ON oi.ProductId = p.ProductId
WHERE o.OrderDate >= DATEADD(month, -3, GETDATE())
    AND o.StatusId NOT IN (5, 6) -- 排除已完成和已取消订单
ORDER BY o.OrderDate DESC;

// 前端订单状态跟踪组件示例
class OrderTracker extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      orderStatus: {},
      isLoading: true
    };
  }
  
  async componentDidMount() {
    try {
      const response = await fetch(`/api/orders/${this.props.orderId}/status`);
      const statusData = await response.json();
      this.setState({
        orderStatus: statusData,
        isLoading: false
      });
    } catch (error) {
      console.error('获取订单状态失败:', error);
      this.setState({ isLoading: false });
    }
  }
  
  renderStatusTimeline() {
    const { statusHistory } = this.state.orderStatus;
    
    return (
      

        {statusHistory.map((status, index) => (
          

            

            

              
{status.statusName}
              
{new Date(status.timestamp).toLocaleString()}
              {status.notes && 
{status.notes}
}
            
          
        ))}
      
    );
  }
  
  render() {
    if (this.state.isLoading) {
      return
