I built a tool that finds the unpaid invoices sitting in your Gmail. Looking for a few users to beta test it.

If you invoice clients by email, you probably know the problem: an invoice goes out, nobody pays, and you only notice weeks later.

You sign in with Gmail and it: goes through the last 90 days of your sent mail and finds invoices that were never paid, with a total of what you're owed drafts a reminder in the same email thread, in your own words, and you d

AI 分析

痛点:自由职业者和小团队通过邮件发出发票后,客户不付款却要等几周才发现,还得硬着头皮写催款邮件,既漏收又尴尬。

目标用户:用邮件(PDF/附件发票)向客户开票的自由职业者、独立顾问、小型代理机构,尤其是没用 Stripe/QuickBooks 内置提醒的人。

证据:an invoice goes out, nobody pays, and you only notice weeks later. Then you have to write the "just following up on this" email, which never gets less awkward. / It's FREE for the first 50 users during the 3 months while it's in beta... If you join now, you'll also get the option to buy it once for life.

变现:Freemium:基础扫描与提醒草稿免费,付费解锁自动跟进序列、多邮箱/多客户、应收看板;可选一次性终身买断(如 49-99 美元)或 8-15 美元/月订阅。

MVP:两周 MVP:Gmail OAuth 授权 → 扫描最近 90 天已发送邮件,识别含 invoice/PDF 附件的邮件并正则+LLM 抽取客户名、金额、到期日 → 检测该线程后续无回复或未出现 paid 关键词 → 在同线程生成个性化催款草稿交由用户确认发送 → 设置页可一键删除全部数据。先不做收件箱智能分类。

竞品:Chaser、Paidnice、Invoiced、Stripe 内置发票提醒、QuickBooks 自动催款、各类 Gmail AI 助手插件

摘要:Reddit r/SideProject 上一个独立开发者发布了 Courtside:用 Gmail 登录后扫描最近 90 天已发邮件,找出未付款的发票并汇总欠款,还能在同一邮件线程内生成催款草稿,兼容普通 PDF 附件发票。产品处于 3 个月 beta,前 50 名用户免费并可选终身买断,说明作者认为该痛点有付费空间,但帖中没有真实付费用户或收入数据,且同类竞品(Chaser、Paidnice、Stripe/QuickBooks 提醒)已较多。
