何时使用定期发票
当您按固定周期向同一客户收取相同金额时，定期发票最为合适。按月固定服务费、订阅服务、持续维护合同和定期咨询业务都是理想场景。无需每个周期手动创建新发票，设置一次即可让系统自动处理。
在 CleverInvo 中设置定期账单
像往常一样创建发票，然后将其标记为定期发票并选择频率：每周、每两周、每月、每季度或每年。设置开始日期，可选设置结束日期。CleverInvo 按时间表生成发票、递增编号、更新日期，并可自动通过邮件发送给客户。
管理定期发票的变更
当固定服务费金额变更或服务合同更新时，编辑定期发票模板即可。未来的发票将使用更新后的金额。之前已生成的发票保持不变，为您保留每个周期的准确计费记录。
