Which of your customers is eating your OpenAI bill? I built a tool that tells you. Looking for 10 founders to try it.

If your SaaS calls OpenAI or Anthropic, the bill arrives as one number. You charge per seat or per plan, but the model cost is per customer, and a few heavy users can quietly eat the margin on everyone else. So I built AgentBill. You wrap your OpenAI, Anthropic or Google client once (Python or Node) and pass a customer_id, and every call gets recorded with its model and tokens against that customer, estimated at list price. You get a monthly report per customer. You can also p

AI 分析

痛点：AI SaaS 按席位/套餐收费，但 OpenAI/Anthropic 成本是按客户消耗计费，少数重度用户悄悄吃掉整体毛利，创始人无法定位到具体是哪个客户在亏钱。

目标用户：已经上线 AI 功能、按席位或套餐定价的中小型 SaaS 创始人与独立开发者（月 API 账单几百到几万美元）。

证据：You charge per seat or per plan, but the model cost is per customer, and a few heavy users can quietly eat the margin on everyone else. / You can also put a dollar ceiling on a single job, and before a call that would cross it you get approved: false back / I'm looking for about 10 founders with AI features in production to try it

变现：SaaS 订阅：免费额度（如每月 50 万 token 记录）后按记录调用量或按客户数阶梯收费 29-199 美元/月；进阶版加预算熔断、告警、成本分摊到 Stripe 账单；也可提供自托管一次性授权。

MVP：2 周 MVP：发布 Python/Node SDK，一行包装 OpenAI/Anthropic/Google client 并强制传 customer_id，记录 model、tokens、按 list price 估算成本，写入 SQLite/Postgres；提供一个只读的按客户月度成本表（含调用量与估算金额），外加单 job 美元上限熔断（超限返回 approved:false）；不做多租户后台、不做计费系统，先用上传 CSV 或简单网页展示。

竞品：Helicone、Langfuse、Traceloop、OpenMeter、Portkey、Metronome、CloudZero

摘要：一位开发者发布 AgentBill，针对 AI SaaS 无法按客户归因 OpenAI/Anthropic 成本的痛点：SDK 包装一次并传 customer_id，即可得到每客户月度成本报告，还支持单任务美元上限熔断（超限返回 approved:false）。目前完全免费、无需信用卡，作者自认不确定用户更在意成本报表还是熔断，正在找约 10 位已上线 AI 功能的创始人试用。帖中没有任何付费意愿原话或收入数据，且 Helicone、Langfuse 等已有同类能力，但“按客户成本归因 + 预算熔断”这一细粒度组合仍有小切口。
