VoiceThere bills real-time voice and agent workloads with usage credits. Credits are a single balance unit across voice time, data sessions, speech services, conversation history, and agent logs. Totals in the dashboard and API are shown to one decimal place (for example 3.3 credits).

How usage is measured

Each billable activity converts to credits using fixed rates. Period totals use raw quantities first — we do not round up per session before summing.

Activity	Unit	Rate
Voice agent time	per minute	2 credits
Data agent time	per minute	0.5 credits
Speech-to-text (local Sherpa)	per 1,000 characters	1 credit
Text-to-speech (local Sherpa)	per minute of audio	3 credits
Conversation history (overage)	per conversation	1 credit
Agent log overage	per 1,000 entries	1 credit
Conversation recording (metered overage)	per minute	1 credit

Speech-to-text and text-to-speech rows apply when your agent uses in-runner local Sherpa. Conversation and agent-log rows apply only after your plan's included quotas for those features.

Subscriptions & included credits

A paid subscription is a seat you assign to exactly one projectat a time. That project receives a monthly included credit allotment based on the seat's plan tier. Included credits refresh at the start of each billing period (aligned with your Stripe subscription or, on the free tier, monthly anniversary from signup).

Plan	Included credits / period
Free	5,000 credits
Budget	10,000 credits
Budget+	20,000 credits
Advanced	75,000 credits
Ultimate	175,000 credits

Unused included credits do not roll over to the next billing period. When a new period starts, included balance resets to the full allotment for that tier.

If you move a seat to a different project, the remaining included balance moves with the seat. Credit packs (below) stay on the project that purchased them.

Manage seats under Organization → Subscriptions. Assign or reassign a seat to a project from the subscription detail view.

Credit packs

Credit packs are one-time purchases tied to a specific project. They add credits on top of subscription included balance and persist across billing periods until used.

Packs burn in FIFO order (oldest pack first).
Buy packs from Project → Usage or from Subscriptions (select the target project first).

Pack	Credits granted
$10 pack	11500.0 credits
$25 pack	32500.0 credits
$50 pack	67500.0 credits

Burn order

When usage is settled, credits are consumed in this order:

Included — subscription allotment for the assigned project
Credit packs — oldest pack first (FIFO)
Metered overage — on-demand usage billed through Stripe (paid tiers with metered usage enabled)
Hard-stop — new sessions and certain operations are blocked when no credits remain and your organization or project budget does not allow further spend

On the free tier, there is no metered overage — when included and pack credits are exhausted, usage stops until the next period or you add packs / upgrade.

Organization & project budgets

Spend caps are organization-authoritative. An optional organization budget limits total metered cash spend for the month. You can set a lower per-project budget, but a project cap cannot exceed the org cap. When both caps apply, organization hard-stops are evaluated before project hard-stops.

Configure org budgets and on-demand metered usage on Organization → Usage.
Per-project metered toggle, conversation/agent-log overage toggles, and optional project cap are on each Project → Overview billing panel. Turning storage overage off after growth above the plan cap freezes the current row count as an elevated rollover ceiling; see Agent logs and Conversation history.
Email alerts can fire at 80%, 90%, and 100% of the org budget (toggle per threshold).
When a budget is reached, affected projects hard-stop even if subscription included credits remain (included credits do not bypass a spend cap).

Payment method & effective metered usage

On-demand metered overage is off by default at the organization and project level. Opt in after you add a payment method on file for your organization Stripe customer (individual or organization billing profile). Until payment is ready, the metered toggle is disabled in the dashboard — sessions stop when included credits and packs are exhausted.

Add or update payment from Organization → Usage (setup checkout) or the Stripe customer portal.
Org and project metered_overage_enabled toggles must both be on for a project to use metered overage after packs.
API: GET /api/v1/org/billing-payment reports readiness; enabling org or project metered via billing-settings PATCH rejects when payment is not ready.

Cash pricing

VoiceThere billing is USD only for now. One usage credit = $0.001 USD (one tenth of a cent). This rate applies when estimating pack value and when metered overage is charged.

On paid tiers with metered overage enabled at the organization and project, with a payment method on file, when included subscription credits and purchased credit packs are exhausted, additional usage is billed as metered overage through Stripe. The free tier does not offer metered overage — usage stops when included and pack balances are gone (see burn order above).

Budget settings cap how much metered cash your organization can accrue in a billing period. Set an organization budget on Organization → Usage; optional per-project caps cannot exceed the org cap. Email alerts can fire at 80%, 90%, and 100%. When a budget is reached, affected projects hard-stop even if subscription included credits remain — see Organization & project budgets above.

Subscription plan prices, pack bonuses, and example session costs are on the pricing page.

Invoices & usage statements

VoiceThere gives you two documents for billing visibility:

Usage statement — a printable credit breakdown from VoiceThere: organization totals and per-project tables by usage kind (voice, STT, TTS, conversations, logs, and so on). Open Organization → Usage → Usage statement or call GET /api/v1/org/usage-statement with the same period filters as usage charts. Use your browser's print or Save as PDF for a shareable snapshot of what was consumed.
Stripe invoice— the cash document from Stripe for subscription seats and metered overage credits converted to money at your plan's overage rate. Hosted invoice links appear on the usage statement page and via GET /api/v1/billing/invoices. Stripe remains the system of record for cards and payments.

Credits on the usage statement do not always equal cash on a Stripe invoice in the same calendar window — included subscription credits, packs, and burn order affect when metered overage reaches Stripe.
