Autumn

Building billing in-house starts simple, but real-time checks, credit ledgers, reset rules, rollovers, custom contracts, analytics, and pricing changes become hard to maintain over time.

Thoughts on billing infrastructure, usage-based pricing, and building for AI startups.

Autumn describes patterns it has adopted while designing its API increasingly for agents rather than humans.

Why Autumn builds around Stripe Billing instead of replacing subscriptions and invoices, and where the real complexity has moved for credit-based pricing.

Metronome is built for sophisticated usage metering and rating. Autumn is built for AI and SaaS companies that need credits, entitlements, enterprise contracts, committed spend, and Stripe billing state in one application-facing system.

Orb is built for usage events, complex pricing queries, ledgers, simulations, and invoicing workflows. Autumn is built to manage application billing state like credits, limits, entitlements, rollovers, reset intervals, and custom packages.

Stripe Billing is the subscription, invoice, and payment layer. Autumn runs on Stripe and adds product-facing billing state for credits, entitlements, access checks, and pricing iteration.

Drop-in billing for AI startups. Stop rebuilding usage limits, credits, and subscription logic. Autumn keeps payments, webhooks, and usage in sync.

Autumn's Privacy Policy covers how it collects, uses, and protects personal information across its billing infrastructure, APIs, and SDKs.
