Pricing models: how an AI phone assistant is billed
Most providers combine a monthly subscription with an included pool of minutes. Once the pool is used up, each extra minute is charged at a fixed rate. Understand the model and you compare offers in minutes, not in marketing promises.
- Base fee (subscription): covers provisioning, a phone number and a minute allowance - usually monthly, or cheaper billed yearly.
- Included minutes: the talk time bundled each month. This is the key comparison figure, not the headline price alone.
- Overage minutes: the price per minute above the allowance. A flat, transparent rate protects you from surprises.
- One-off costs: setup, number porting or onboarding. Good SMB offers skip these.
Think in minutes: multiply your monthly calls by the average call length. 200 calls of two minutes each is about 400 minutes a month, which lands you in the middle tier with most providers.
AI phone assistant pricing 2026: concrete examples
To make the order of magnitude tangible, here are CallAssistant's transparent plans. The yearly price is billed per month, all prices exclude VAT, and every extra minute is a flat CHF 0.89 - on the free plan and the largest one alike.
| Plan | Yearly (per month) | Monthly | Incl. minutes | Extra minute |
|---|---|---|---|---|
| Free | CHF 0 | CHF 0 | 30 min | - |
| Starter | CHF 76 | CHF 89 | 120 min | CHF 0.89 |
| Business | CHF 161 | CHF 189 | 350 min | CHF 0.89 |
| Professional | CHF 297 | CHF 349 | 900 min | CHF 0.89 |
| Scale | on request | on request | approx. 2,000 min | CHF 0.89 |
The free plan is not a trick: 30 minutes a month are enough to test the assistant on real calls before you spend a franc. You get the value before you buy - and every paid plan carries a 30-day money-back guarantee.
Cost comparison: AI, answering service or your own receptionist?
The honest question is not only what the AI phone assistant costs, but what the alternative costs. A human answering service and an in-house receptionist solve the same problem - at very different prices and with very different availability.
| Solution | Typical cost per month | Availability | Languages |
|---|---|---|---|
| AI phone assistant | from CHF 76 + minutes | 24/7, several calls in parallel | DE/FR/IT/EN |
| External answering service | CHF 500-1,500 | Business hours, some 24/7 | mostly one |
| In-house receptionist | CHF 4,500-6,500 (full time) | Office hours | 1-2 |
| Answering machine / voicemail | CHF 0-20 | Always on, but takes no action | - |
The point is not to replace people. An AI phone assistant catches the calls that would otherwise be lost - after hours, on weekends, while you serve the customer in front of you. See our comparisons answering service vs. AI and receptionist vs. AI for the detail.
What drives the cost?
Two businesses on the same plan rarely pay the same. Four factors decide your actual bill:
- Call volume: more calls means more minutes. This is the biggest lever - estimate honestly, not optimistically.
- Call length: a plain booking takes a minute, a consultation takes five. Shorter, well-structured calls lower the cost.
- Feature scope: calendar integration, rule-based transfer, lead qualification or multilingual answering can set the tier.
- Overage rate: the price per extra minute. A flat rate like CHF 0.89 is predictable; tiered or opaque models are not.
Choosing an AI phone assistant for your SMB: 8 criteria
The cheapest plan is rarely the right one. These eight criteria separate an SMB-ready offer from one you regret later. Take the list into the sales call.
| Criterion | Why it matters | Question to ask the provider |
|---|---|---|
| Multilingual | Swiss callers speak DE, FR, IT or EN | Are all national languages recognised in the same call? |
| Swiss data location | revFADP and GDPR require clean data handling | Where is call data hosted and processed? |
| Keep your number | Your customers know your number | Can I keep my current phone number? |
| Calendar integration | Book live instead of calling back | Does the assistant book straight into my calendar? |
| Transfer / triage | Urgent cases belong with a human | Can it hand off to staff by my rules? |
| Transparent pricing | Hidden fees eat the savings | Are there setup, number or minimum-term costs? |
| Free to try | Value before you buy, no blind purchase | Can I test with real calls for free? |
| Cancel monthly | No lock-in with a new provider | Is the term cancellable monthly? |
Avoiding hidden costs
The advertised monthly price is not always the whole bill. Ask specifically about the items that like to hide in the small print:
- Setup or onboarding fees - SMB-ready offers should waive them.
- Costs per extra phone number or to port your existing number.
- Minimum terms and notice periods that lock you in for months.
- Surcharges for more languages, integrations or higher call quality.
- Opaque overage rates that only become visible on the invoice.
When does an AI phone assistant pay off?
An AI phone assistant pays off the moment it rescues more missed calls than it costs. For most SMBs a single won customer covers the monthly price - everything above that is profit. A missed call is rarely just a call: the caller dials the next provider who picks up.
Worked example: miss five calls a week, and if every third is a job worth CHF 200 on average, about CHF 1,300 a month walks out the door. Against a plan from CHF 76, the maths is clear. Use our ROI calculator to plug in your own numbers.
Takeaway: start small, think in minutes
For most Swiss SMBs the fair price of an AI phone assistant sits in the low three-figure francs per month - well below an answering service and a fraction of an in-house receptionist. Start free, measure your real minutes, then pick the tier. That way you pay for results, not promises.
