Usage based and metering billing

Bill what was used, and prove it before you send.

Events land as they happen, get rated on the contract's own table, and reconcile to the invoice with a checksum. Five metering models, one revenue graph.

Rated and reconciled

Every line ties back to the events behind it.

A checksum reconciles the invoice to its event stream before it can send.

$218,138.34
December, billed on actual volume at $0.010 per API call.

Usage and metering

Rated on the contract's own table.

No commitment

Pay as you go

The customer pays only for what they use. No commitment and no minimum.

A cloud infrastructure provider charges $0.010 per API call and invoices monthly on actual volume. December billed $218,138.34.

Use cases

Real-time ingestion, rating against the contract table, and a checksum that reconciles the invoice to its event stream before it can send.

Volume

Tier based

The unit price falls as volume climbs, and each tier prices only the units inside it.

A customer at 60,000 calls pays across three tiers: 10,000 at $0.040, 40,000 at $0.030 and 10,000 at $0.022.

Use cases
CommunicationsMessaging platformsPayment processing
Verlix handles

Graduated and volume tiers, tier boundaries that move at renewal, and the arithmetic that shows which units priced where.

Balance

Prepaid credit

The customer buys a balance up front and draws it down. It stays a liability until it is used.

A data provider sells $50,000 of credits. By June the customer has drawn 86%, leaving $7,000 and a top-up decision.

Use cases
Professional servicesMarketplacesAdvertising
Verlix handles

Wallet balances, drawdown at the rated price, expiry and breakage, and the deferred balance the credit represents until it is used.

Minimum

Commit consumption

The customer commits to a minimum. Below the line they pay it, above it overage bills at standard rates.

A payments platform commits to $100,000 a year. Consumption reached $312,151.20, and June ran above the line.

Use cases
Cloud platformsEnterprise productivityAPIs
Verlix handles

Commitment tracking, rollover where the contract allows it, overage at the agreed rate, and a true-up that does not wait for renewal.

Delivery

Milestone based

Billing follows delivery. Each milestone bills when it is accepted, not when an invoice dates.

A rollout bills at kick-off, design sign-off, integration and go-live. Three are billed and go-live is scheduled at $150,000.

Use cases
ImplementationProfessional servicesFixed-scope builds
Verlix handles

Milestone tracking, contract-based triggers, partial invoicing, and the point-in-time recognition each acceptance produces.
