Meter
Track AI and API usage per customer and turn it into accurate bills.
What it does
Record every metered event, such as tokens, API calls or documents processed, roll it up per customer and billing period, and send it to Stripe usage-based billing. Late or corrected events update the bill without double-counting.
The problem
Usage billing breaks in quiet ways: events counted twice, events arriving after the invoice, and no audit trail when a customer disputes a bill.
