Key takeaways in 30 seconds
- An AI phone agent costs from around 49 USD/month for a small business, depending on the call-minute volume included.
- The right calculation is not the price of the tool, but what it brings in: every recovered missed call is a customer won.
- Pricing is modular: you can take voice only, messages only, or both.
- No hardware, no hiring: the agent runs on a dedicated line, ready to answer 24/7.
What drives the price of an AI voice agent
The cost of an AI phone agent depends mainly on two things:
1. Call volume — the more calls you receive, the more minutes are handled.
2. What the agent does — answering simple questions costs less than a full booking or synced appointment flow.
Unlike a receptionist or a call center, there is no salary, no payroll taxes, no hardware: the agent is a software service running on a dedicated line.
The price tiers, concretely
At AeviaInbox, pricing is modular and the price per tier is the same whatever mode you choose (messages only, voice only, or both) — only the included quota changes:
- Starter — 49 USD/month: for a small volume of calls or messages.
- Growth — 99 USD/month: for a steady flow.
- Pro — 199 USD/month: for a sustained volume.
- Business — 399 USD/month: for a high volume.
- Scale — 999 USD/month: for the largest needs.
The appeal of this model: you do not pay for an opaque "all-inclusive" bundle. If you only need voice, you take voice; if you also want WhatsApp and email, you switch to the combined mode.
The real comparison: tool vs missed calls
To judge the price, compare it to the cost of doing nothing. A simple example:
- A restaurant missing 3 bookings a day at a 120 EUR average check loses around 360 EUR/day in potential revenue.
- A garage missing 2 appointment calls a day loses two jobs.
Against those numbers, a subscription at 49 to 199 USD/month pays for itself in a handful of recovered calls. It is that gap — a few tens of euros a month versus hundreds in lost sales — that makes an AI voice agent worthwhile for a small business.
What is included (and what is not)
Included in a service like AeviaInbox:
- The line and the AI voice agent.
- Natural-language understanding and answering in the customer's language.
- Actually creating bookings/appointments and syncing the calendar.
- POS integration for restaurants (HubRise / Popina).
To check for your needs: the minute volume of the tier you pick, and whether you also want the messaging channels (WhatsApp, Instagram, email) on top of voice.
Frequently asked questions

Do I need hardware or a technical setup?
No hardware: the agent runs on a dedicated line, with no heavy installation.
Does the price go up if I get more calls?
You pick a tier suited to your volume; if the volume grows, you move up a tier.
