My SAAS is making $175 MRR but $42 went to API and hosting bills. How do you track what you keep each month?

When I was building my SAAS, I realized I needed a way to calculate the money I was actually making after costs each month. I would check it manually be opening the dashboard of each provider, so for me Polar, Firecrawl, Resend, Twilio and OpenAI and add them up manually. Or I would ask claude to query each's MCP/CLI to figure it out, which took some time and tokens. Railway doesn't even bill on the calendar month (mine runs from the 16th to the 16th), so the numbers never lin

AI 分析

痛点:独立SaaS开发者难以聚合多个API/云服务账单,无法实时知道扣除成本后的真实利润,且各服务计费周期不一致。

目标用户:独立开发者、微型SaaS创始人,尤其是大量使用OpenAI、Firecrawl、Twilio、Resend、Railway等按量付费服务的团队。

证据:I realized I needed a way to calculate the money I was actually making after costs each month. I would check it manually be opening the dashboard of each provider... Railway doesn't even bill on the calendar month... Last 30 days: $164 in revenue, $42 in API and hosting bills.

变现:开源核心+托管付费版,按月订阅提供自动同步、真实利润看板、成本预警、团队协作和税务/发票导出;也可按集成数量或账单金额抽成。

MVP:2周内做一个托管版利润看板:接入Stripe/Polar收入与OpenAI/Resend/Railway/Twilio等5个成本源,按日归一化不同账单周期,计算MRR、成本、毛利和单客户利润,并发送每周利润邮件。

竞品:Baremetrics、ProfitWell、ChartMogul、Pry、OpenProfit

摘要:发帖人的SaaS月收入约175美元,但42美元用于API和托管,因各服务账单周期不同,手动核对真实利润很麻烦。他为此开源了openprofit.dev,已有19个集成和MCP,说明痛点真实,但帖子未体现付费意愿,且核心工具已MIT开源。变现需靠托管版或团队增值功能,面向微型SaaS的付费能力有限。
