Every rate, itemised
Every minute is made of three parts, and each row bills only the parts Tone runs. Whether Tone runs the agent is set per phone number, so one organization can mix these.
| How you use it | Agent | Telephony | Platform | Number rental | Rate |
|---|---|---|---|---|---|
| Developer Tone number, Tone agent — list price | ₹3.00 | ₹0.50 | ₹1.50 | from ₹299/mo | ₹5.00 / min |

The Enterprise row is the starting rate; yours is agreed with us and falls with volume. Bring-your-own and SIP-trunk rates are the same on both plans. SIP trunking is enabled per organization on request.
In every minute, at no extra cost
There are no add-ons to buy. What a call does is in the rate.
The compliance gate
DLT, calling hours, Do-Not-Call, consent and the auto-dialer declaration — checked before every dial, refused calls never placed.
DND register lookups
Promotional calls are checked against India’s DND register, per call and in bulk at campaign launch.
Sealed evidence
A tamper-evident record of what was checked and what happened, for every call attempt.
Recordings and transcripts
Call recordings, full transcripts and the fields your agent collected, on every call.
Signed webhooks
Every call event delivered to your URL, HMAC-signed, retried, and replayable.
Campaigns
Upload a list, pace the dialling, retry no-answers. No per-campaign or per-contact fee.
Knowledge bases
Upload documents or a website and the agent answers from them during the call.
Every voice and model
Eleven Indian languages and every voice and model in the agent editor, at the same rate.
What never costs anything
Test mode
A tone_test_ key runs the whole API against magic numbers. Calls are priced and never charged; going live is a key swap.
Dashboard test calls
Talk to your agent from the browser, or chat with it, without spending a rupee. A daily allowance applies.
Calls nobody answered
Busy, no answer, voicemail or a failed dial cost nothing. Only answered calls are billed.
Questions
The full mechanics — the ledger, top-ups and invoices — are in the billing docs, and refunds in the refund policy.
What is the difference between Developer and Enterprise?
The rate. Both are pay as you go with every feature. Developer is ₹5.00 a minute for everyone, from the moment you sign up. Enterprise starts at ₹4.00 per connected minute, agreed with us for your organization, and the more minutes you run the lower it goes.
Is there a subscription or a monthly minimum?
No. Neither plan has a subscription, a platform fee or included minutes. You add money to a prepaid wallet (from ₹100) and calls, numbers and verdicts are debited from it as you use them.
How is a call billed?
Per second, on connected calls only, with a 30-second minimum. On Developer a 45-second call costs ₹3.75, and a 10-second answered call is billed as 30 seconds: ₹2.50. Busy, unanswered and voicemail calls cost nothing.
Is GST included?
Rates exclude GST. It is added once, when you top up: adding ₹1,000 costs ₹1,180 and your balance grows by exactly ₹1,000. Nothing debited afterwards carries GST, and every top-up gets a GST tax invoice.
Does the voice or the language model change the price?
No. Every voice, language and model the agent editor offers is inside the same per-minute rate.
What do phone numbers cost?
From ₹299 a month. Each number is priced on its own, and the dashboard shows the exact rental before you buy. It renews monthly from the wallet; a number on your own SIP trunk has no rental at all. 140- and 160-series numbers are available on request.
What happens when my balance runs low?
A live call is refused, rather than placed, below ₹12. Campaigns pause themselves at the same point, and a wallet.balance.low webhook and email warn you before it gets there.
Can I get my money back?
Yes. Unused balance paid for with real money is refundable, GST included. The refund policy has the details.
Do the bring-your-own-voice and SIP-trunk rates change on Enterprise?
No. Those rates are already the parts of a minute Tone runs, so they are the same on both plans. The Enterprise discount applies to full-stack calls, where Tone runs the agent.
