Usage Invoice

Meter usage. Invoice in Stripe.

Self-serve under the Orb / Metronome / Lago cliff. B2B, Stripe at signup, no sales call. Caps are constants in the repo — not a quote.

How it works

Start on Pro

Meter usage

Your product POSTs events — or we poll a meter. meter, quantity, optional timestamp, idempotency key.

We aggregate

Events land on your meters. Caps live in code. You see the log; your customers can too.

Invoice in Stripe

A daily cron rolls the previous period into invoice items or metered subscription lines. No human in the loop.

Guardrails

Built for machines. Bounded for people.

UsageMill is B2B infrastructure. We meter what you send. We do not sit in the invoice path as a human reviewer. Abuse of the API, scraping, or using us to bill consumers in a way that breaks card-network rules is out.

Acceptable use. Business usage events only. See the AUP.
No human in the loop. Magic link, API key, cron. Support is email, not a CSM.
Caps in code. Starter, Pro, and Scale limits are constants. Hit a cap and the API says so.
