I built an invoicing tool where you only pay when you send. 41 bucks on Meta ads got 0 signups, one Reddit comment thread got 100 visits

Kept seeing freelancers complain they pay 30 to 65 a month to send like 4 invoices, and Harvest just hit people with 5x price jumps. So I built the opposite. 3 invoices a month free, 2 bucks each after that. No subscription unless you actually send a lot It does the annoying part. Tells you when the client opened it, sends the day 3 / 7 / 14 reminders so you're not the one texting "hey just checking in," and you tap mark paid when the money hits. Client pays you however they already pay you

AI 分析

痛点:低频开票的自由职业者被迫为每月只发几张发票支付 30-65 美元/月的订阅费,且 Harvest 等工具大幅涨价,价格与实际用量严重不匹配。

目标用户:每月只发 3-10 张发票的自由职业者、独立顾问、小工作室

证据:Kept seeing freelancers complain they pay 30 to 65 a month to send like 4 invoices, and Harvest just hit people with 5x price jumps. / spent 41 bucks on Meta ads, 75 people clicked, zero signed up / a Wave user argued with me for an hour about whether Wave's really free

变现:按发票计费(3 张免费,之后 2 美元/张)或低价年费订阅;后续可加收款提醒、自动催收、多币种等增值功能做分层定价

MVP:两周内用 Next.js + Postgres + Stripe + Resend 做出:无账号创建发票、邮件打开追踪、day3/7/14 自动催款提醒、一键标记已付,先不碰资金流

竞品:Wave、Harvest、FreshBooks、Bonsai、Zoho Invoice、Invoice Ninja、Invoice Simple

摘要:作者发现自由职业者为每月几张发票却要付 30-65 美元/月而抱怨,Harvest 又涨价 5 倍,于是做了按张计费的发票工具(3 张免费、之后 2 美元/张),带打开追踪和自动催款,2 周 solo 完成。但 41 美元 Meta 广告带来 75 次点击、0 注册,而一条 Reddit 评论帖就带来 100 次访问,转化路径尚未验证。付费意愿来自竞品涨价与订阅费的抱怨,但发票赛道竞品密集且免费替代品多,需谨慎评估。
