Usage-based billing
Usage is priced on each customer's own rate card and checked against the invoice before it sends.
Usage checks
Before an invoice sends, its usage is counted against each line, and duplicates come out.

June, billed at $0.010 per API call and matched to its usage before it could send.
Pricing models
No commitment
The customer pays only for what they use, with no minimum.
Gadwall Fustian Inc pays $0.010 per API call with no commitment. June billed $218,138.34.
Usage priced at the contract's rate and matched to the invoice before it sends.
Volume
The unit price falls as usage climbs, and each tier prices only the units inside it.
Machair Worsted Inc's June ran 2,040,000 events across 3 bands: 500,000 at $0.012, 1,000,000 at $0.009 and 540,000 at $0.006, so $18,240.00.
Graduated and volume tiers, and an invoice that shows which units priced where.
Balance
The customer buys credit up front and draws it down; until used, it stays a liability.
Hoarfrost Cambric Inc bought $50,000 of credit on 1 January and had drawn 86% by June, leaving $7,000.
Balances, drawdown and expiry, with unused credit recognised when it lapses.
Minimum
The customer commits to a minimum; usage above it bills at the agreed overage rate.
Fanlight Betony Inc commits to $100,000 a year. It passed the line in October, and usage reached $312,151.20 by June.
Commitment tracking, rollover where allowed, and a true-up when the contract calls for one.
