## What it is
Lotus is an open-source pricing and billing engine for SaaS companies, supporting usage-based, per-seat, and enterprise plans. It provides a self-hosted control panel to deploy, monitor, and experiment with pricing models on top of existing quote-to-cash stacks.

## Use cases
- implement usage-based billing for a SaaS product
- manage per-seat and enterprise subscription plans
- experiment with pricing and packaging models
- self-host a billing engine on top of existing payment stack
- track and meter product usage for invoicing

## When to choose
- you need flexible custom subscriptions beyond what Stripe Billing offers
- you want an open-source, self-hosted pricing engine
- you need to iterate on pricing models without code changes

## When to avoid
- you only need simple flat-rate monthly billing
- you want a fully managed hosted billing solution
- your stack is not Python/TypeScript friendly

## Facets
