Billing
How billing works
- Credits are deducted after each call, based on its duration and the model used.
- In call history you can see the credits for each call, separately for voice and for the model.
- Burst is disabled by default; a burst call is charged double for voice and is marked in the history.
- Silence longer than 10 seconds is charged at a reduced rate.
- Queue waiting time is not billed.
- At zero balance, new calls do not start.
- Reloading is done manually or automatically, at a threshold chosen by you.
- Unused credits are rolled over for up to 2 months.
Separate
What is not included in credits
- Phone numbers and the telecom operator's minutes.
- Agent implementation: from $500, one-off.
- Custom work: new integrations, scenarios or reports made to order.
Enterprise
For large volumes
The terms are set out in the contract, after we see the volume and the integrations you need.
- Credits for high volume, under negotiated terms.
- Monthly billing per company.
- Integrations with your systems, built on request.
- Agents and campaigns according to team needs.
Frequently asked questions
Why credits and not minutes?
A minute costs differently depending on the model, the prompt and the knowledge base. With credits, you pay exactly what your agent consumes, not an average rate that does not suit you.
Why does the number of minutes differ between models?
Voice costs the same on any model. What differs is the cost of the model that thinks up the response: larger models cost more per minute, so the same credits cover fewer minutes.
What happens when the credits run out?
New calls no longer start until you top up. You can enable auto top-up so the agent does not stop.
Can I change the agent's model?
Yes. The new per-minute rate applies from the moment you save, and the history keeps the model used for each call.
What is burst?
Calls above the simultaneous call limit can go into burst, charged at double the voice rate. It is disabled by default and is turned on only with your agreement.
What does implementation include?
The scenario, voice, knowledge base, tools, CRM connection, and tests on real conversations before launch. Costs from $500, one-off.
Is telephony included?
No. Phone numbers and operator minutes are paid separately; we check your operator before the quote.
What happens to unused credits?
Rolled over to the following month, for up to 2 months.
How much does one voice minute cost?
150 credits per minute, that is $0.15, plus the model. On the standard Kallina model, the reference agent consumes around 203 credits per minute.
