为什么自由职业者需要专业的发票生成器
自由职业者需要同时管理多个客户、不同的项目范围和各种计费周期。专业的发票生成器让您无需在 Word 或 Google Docs 中从零开始制作发票。只需设置一次企业信息，选择客户，添加与实际交付物对应的明细项目，即可导出专业 PDF。统一的格式让您的账单更加专业，减少在行政事务上花费的时间，把更多精力放在创收工作上。
自由职业发票应包含哪些内容
每张自由职业发票都应包含：您的企业名称和联系方式、客户名称、唯一的发票编号、开票日期和到期日期、包含数量和费率的服务明细清单、应付总额，以及您接受的付款方式。如果您在合同或报价中约定了特定的付款条件，请在发票上注明，以避免付款时间上的歧义。
CleverInvo 如何帮助自由职业者更快收款
CleverInvo 允许您保存客户资料，无需每次重新输入信息。您可以复制之前的发票用于重复性工作，跟踪哪些发票尚未付款，并在到期日过后发送付款提醒。免费版涵盖基本的发票生成和 PDF 下载，付费版增加邮件发送、定期账单和客户门户等功能，让客户可以直接查看和支付发票。
