Billing and pricing

Tried is prepaid and pay as you go. You buy credit, and each call, chat and metered feature draws it down. There is no subscription plan. Billing is per workspace and is managed by admins on the Billing page.

How a call is priced#

All prices are in Australian dollars (AUD), excluding GST. GST is added on invoices.

A voice call is the sum of per-minute components. The price of each component depends on the agent's configuration, and the agent builder shows the total as Cost in the header before you deploy (see Estimated latency and cost).

There is no telephony charge. You bring your own numbers over SIP or your own Twilio account, and your carrier bills the phone line as it does today. Web calls cost the same as phone calls.

The lowest all-in rate is $0.16 per minute: GPT-4.1 mini ($0.02) with a Standard voice ($0.06) plus voice infrastructure ($0.08). The default agent, GPT-5.6 Terra with a Premium voice, is $0.30 per minute.

LLM prices#

Voice prices#

Agents moved from Retell with another voice_model are billed at that model's rate, on a voice_<voice_model> line. See Voice.

Example#

An agent on gpt-5.6-terra with a Premium voice and a knowledge base:

A 2 minute 10 second call costs 130 / 60 x 0.31 = $0.672. On the Standard tier the same call costs $0.542.

Per-second billing#

Duration is rounded up to the next whole second, and each line costs unit_price x seconds / 60. There is no minimum and no per-minute rounding. The result is stored on the call as call_cost:

{
  "call_cost": {
    "product_costs": [
      { "product": "voice_infra", "unit_price": 0.08, "cost": 0.173333 },
      { "product": "gpt-5.6-terra", "unit_price": 0.1, "cost": 0.216667 },
      { "product": "voice_premium", "unit_price": 0.12, "cost": 0.26 },
      { "product": "knowledge_base", "unit_price": 0.01, "cost": 0.021667 }
    ],
    "total_duration_seconds": 130,
    "combined_cost": 0.671667
  }
}

See The call object for the other call fields.

Additional usage lines#

These lines are added to call_cost after the call when they apply:

Transfers add no charge: the transferred leg runs on your own trunk, so your carrier bills it.

Other usage#

GET /billing/platform-usage breaks down contact memory, QA minutes and Conductor credits for the current month.

Credit balance#

The Credit balance card shows the balance, how much has been added and used, and the status Active or Out of credit. Every new workspace gets a $15 Free trial credit grant the first time billing is read.

The balance is credits added minus the cost of calls. Platform usage (contact memory, QA, Conductor) and purchased concurrency are recorded as negative entries in the credit ledger.

Buy credits#

Admins click Buy credits and pick $20, $50, $100, $500 or a custom amount between $5 and $10,000.

• The dialog calls POST /billing/add-credits, which charges the saved card. With STRIPE_SECRET_KEY set on the API Needs keys, the charge goes through Stripe.
• Without it, no card is charged and the credit is added immediately with a mock payment reference.
• POST /billing/checkout is the hosted alternative: with Stripe it returns a Stripe Checkout URL. The credit is added when Stripe reports the payment to POST /webhooks/stripe (see below).

Stripe webhook#

Credit bought through Stripe Checkout (/billing/checkout or /billing/checkout-session in payment mode) is added when Stripe calls the API. In the Stripe dashboard, add a webhook endpoint at https://<your API host>/webhooks/stripe for checkout.session.completed and checkout.session.async_payment_succeeded, then set its signing secret as STRIPE_WEBHOOK_SECRET on the API Needs keys.

Requests without a valid stripe-signature (or older than five minutes) get 401. Each paid session adds its amount as a purchase credit and a paid invoice once, however many times Stripe retries it.

Every purchase creates an invoice.

What happens at zero#

When the balance is zero or below, new phone calls, web calls, registered calls, batch calls and chats are refused with 402 and error_code: "credit_exhausted". Calls already in progress continue. Outbound calls also check the balance before dialling (Insufficient credit balance. Add credits to place calls.).

Auto-recharge#

Auto-recharge buys credit automatically when the balance falls below a threshold. It needs a saved card.

The check runs every minute and right after you change the settings. A failed charge is not retried until the next check; the attempt is reported as auto_recharge_failed by POST /billing/check. Each successful recharge gets an invoice of kind auto_recharge.

Monthly budget#

Set Budget per calendar month ($) to cap spend. Month usage counts call costs, chat costs and platform usage since the first of the month (UTC).

• At 80%, Tried sends a budget_alert webhook to the workspace webhook URL.
• At 100%, it sends budget_reached, and new calls and chats return 402 with error_code: "budget_reached" until you raise the budget or the month ends.

Each alert is sent once per month. The card shows the percentage used, or Reached: new calls blocked.

{
  "event": "budget_alert",
  "billing": { "month": "2026-10", "monthly_budget": 500, "month_usage": 401.25, "percent": 80.3, "threshold": 80 }
}

Payment methods#

The Payment method card shows the saved card (brand, last four digits, expiry).

• With Stripe Needs keys: Add card opens Stripe Elements against a SetupIntent. Card details go straight to Stripe. We keep only the brand, last four digits and expiry. Tried creates one Stripe customer per workspace. Customer portal opens Stripe's billing portal, where you can manage cards and see Stripe receipts.
• Without Stripe: the card form is a test form. Test mode: Stripe isn't configured, so the card is not checked or charged.

Invoices#

Every credit purchase and auto-recharge creates an invoice numbered TR-<yyyymm>-<digits>, listed in the invoices table with Number, Date, Type, Status and Amount. View opens a printable HTML invoice (GET /billing/invoices/:id/html) with a Print or save as PDF button.

POST /billing/invoices/usage with { "month": "2026-09" } creates a usage statement for a past month: a record of usage that was drawn from prepaid credit, marked paid.

Account states#

States are derived from unpaid invoices unless the operations team pins one. GET /account-status returns the state, label, reason and what it blocks. When a state is not active, a banner across the dashboard explains it with Open billing or Verify business. See Business verification.
