Introduction

Summerbase gives software companies their subscription metrics: MRR, ARR, churn, retention, expansion and cohorts. It is built for AI-era companies, where each customer has a real cost to serve, mostly LLM and inference spend. It is designed to show that cost next to each customer’s revenue, so you can see your margin customer by customer.

Note

Per-customer costs can’t be sent to Summerbase yet. These docs cover revenue and customers, which work today.
