What does an AI receptionist really cost in Switzerland?

"How much does it cost?" That is the first question I get about voice agents — and most answers you find online are either a per-minute price that includes nothing, or an agency quote that includes everything. Here is how the bill for an AI receptionist really breaks down for a Swiss small business, and how to estimate it on your calls before signing anything.

First: what an AI receptionist does (and does not do)

An AI receptionist picks up, understands the request in natural language, answers simple questions — opening hours, address, prices, lead times —, takes a message or offers a slot, and transfers to a human when the call goes beyond its frame. It does not replace your front desk: it absorbs out-of-hours calls, peaks, and the questions that come back a hundred times a week.

The four items on the bill

1. Set-up (one-off)

This is the big one, and that is normal: writing the greeting script, gathering your information (frequent questions, prices, hours), connecting the calendar or CRM, defining the transfer rules, then testing with real calls. With me, an AI agent starts from CHF 4,000 — the exact price depends mostly on how many tools need connecting.

2. Running costs (per minute)

Every minute of a call uses several building blocks, each billed by its provider: the number and telephony, speech transcription, the language model that understands and answers, and the speech synthesis that talks. Prices vary by provider and volume, and they keep falling — which is why I will not give you a per-minute price here that would be wrong in six months. The right method is to calculate it on your own figures:

Minutes per month = calls per day × average call length × working days.
Example: 30 calls × 3 minutes × 22 days = 1,980 minutes.
Monthly cost = minutes per month × total per-minute price of the chosen building blocks.

In a first conversation, I run this calculation with you, using the current prices of the selected providers.

3. Follow-up (monthly, optional)

A voice agent is never "finished": your hours change, a new question appears, an answer needs correcting. Follow-up covers updating the information, reviewing conversations and monitoring costs. With me, monthly follow-up starts from CHF 900 per month — and it remains optional: some clients prefer to call on me as needed.

4. Hidden costs

• Your time: gathering information, testing, approving. Plan a few hours at the start.
• The legal frame: the Swiss data protection act (revFADP), in force since 1 September 2023, already applies to AI. The Federal Data Protection Commissioner has pointed it out: people must know they are talking to a machine, and what happens to their data. Plan for it from the start, not afterwards.
• The cap: without a spending limit, a misconfiguration or a looping call can inflate the bill. I always cap consumption.

When it is worth it — and when it is not

It is worth it if you get many repetitive calls, if you miss some of them (out of hours, in a meeting, on site), or if every missed call is a lost customer — practices, tradespeople, shops, rentals.

It is not worth it if you get a few calls a day, if most are complex or sensitive (advice, complaints, difficult situations), or if your customers explicitly expect a human voice. In that case, I will tell you — often, a well-designed form or a better contact page is enough.

How I work

1. A free conversation: your volumes, your frequent questions, what missed calls cost you today.
2. The minutes calculation and a written quote, set-up and running costs separated.
3. A pilot on a narrow scope — for instance out-of-hours calls only.
4. We measure, adjust, then widen the scope (or stop).
