AUTOMATED BILLING
Turn charging sessions into revenue, automatically.
Every session becomes a metered charge record and a payout. Ampr measures the energy, applies your tariffs, and settles funds through Stripe, so you collect revenue without building a billing engine.
FROM PLUG-IN TO PAYOUT
The whole billing chain, handled.
Calibrated metering
Ampr reads meter values straight from the charger and records the energy delivered, so every session rests on real numbers.
Your tariffs, applied
Set pricing by energy, time, session, or location. Ampr applies the right tariff to every session without manual work.
Immutable charge records
Each session closes into a CDR you can hand to an auditor, a driver, or a roaming partner. Once written, it never changes.
Payouts through Stripe
Funds settle to your account through Stripe Connect, so revenue lands without a separate payments integration.
BILLING THAT HOLDS UP
Metering the regulators accept.
Some markets require calibrated, signed metering before you can bill a driver. Ampr records sessions to that standard, so a charge you issue is one you can defend.

Sessions, tariffs, and CDRs as REST resources.
Everything billing does is available to your engineers through one REST API and webhooks, so you can reconcile revenue and reflect charges in your own product without exports.
