实施建议

🎯 开发优先级

第一阶段： 搭建Clean Architecture基础框架，实现基本的多租户数据隔离
第二阶段： 集成QuestPDF实现专业发票生成，满足新西兰GST合规要求
第三阶段： 实现JWT认证系统和基于角色的权限控制
第四阶段： 优化Azure SQL弹性池配置，实现成本控制和性能监控
第五阶段： Docker容器化和CI/CD流水线部署

⚠️ 关键注意事项

新西兰税务合规： 从2023年4月起，使用"应税供应信息"(TSI)替代传统税务发票
数据安全： 确保多租户数据严格隔离，实施全面的访问控制
性能优化： 使用Azure弹性池和缓存策略，支持大规模并发用户
成本控制： 合理配置资源池，利用Azure混合权益节省成本
