"How much does an AI phone assistant cost?" Short answer: between €79 (excl. VAT) and over €10,000 per month, depending on the category of solution. A 1-to-100 spread that is actually easy to explain — but that few vendors bother to break down before sending a quote.
In this guide, we lay out the real 2026 market price ranges, category by category: the typical billing model (subscription + minutes), the 4 factors that drive the bill up, an honest comparison with a salaried receptionist and a human outsourced answering service, a concrete ROI calculation for an SMB missing 2–3 calls a day, and the 5 traps to spot before signing anything.
How much does an AI phone assistant cost in 2026?
In 2026, an off-the-shelf solution for SMBs costs between €79 and €300 (excl. VAT) per month in subscription fees, plus per-minute billing for calls (typically €0.15 to €0.30/min). A custom enterprise solution runs between €2,000 and €10,000 per month, deployment fees on top. Building your own agent in-house starts at €15,000–50,000 of upfront investment, before maintenance. Here is how it compares with the human options:
| Solution | Total monthly cost | Best for |
|---|---|---|
| Salaried receptionist (full-time) | €2,600 – 3,000 incl. payroll charges | Front desk + phone, office hours |
| Human outsourced answering service | €300 – 1,500 excl. VAT | SMBs wanting a human voice during the day |
| Custom enterprise AI | €2,000 – 10,000 + setup | Large accounts, call centers |
| Off-the-shelf AI assistant | €79 – 300 excl. VAT + €0.20/min | Small businesses and SMBs, 24/7 coverage |
The category of solution matters far more than the brand: let's see why an AI phone switchboard for an SMB shouldn't cost as much as an IT project.
The 3 categories of solutions and their real prices
The voice AI market has settled into three clearly distinct tiers. Mixing up the categories is like comparing a city car with a heavy truck.
1. Off-the-shelf solutions for SMBs: €79 to €300/month
The category that fits 95% of small businesses. The vendor configures a tailor-made AI voice agent (opening hours, services, tone, transfer rules), go-live takes about a week, and standard integrations are included: calendar, email summaries, urgent calls forwarded to your mobile. The subscription covers the platform and support; call minutes are billed based on actual usage.
2. Custom enterprise solutions: €2,000 to €10,000/month
Aimed at large accounts and call centers: deep integrations into the company's IT systems (proprietary CRM, corporate telephony, business databases), a dedicated project team, contractual service-level commitments. Deployment takes several months and setup fees run into thousands of euros. Worth it from several thousand calls per month — oversized below that.
3. Custom development: €15,000 to €50,000 to get started
Building your own agent with developers and voice and telephony APIs. On top of the initial cost come recurring costs (per-minute API billing, hosting) and above all maintenance: models to update, scenarios to supervise, bugs to fix. For an SMB, this is almost always the least profitable choice.

The typical billing model: subscription + minutes
The 2026 market standard: a fixed monthly subscription (platform, configuration, support) plus a per-minute call price (actual usage). It is a healthy model: you only pay the variable part when the agent is actually working.
Total cost: AI vs receptionist vs outsourced answering service
For a comparable scope (answering the phone, booking appointments, taking messages), an AI assistant costs 10 to 20 times less than a salaried receptionist and 2 to 8 times less than a human outsourced answering service — while also covering evenings, weekends and public holidays at no extra charge.
- Salaried receptionist: €2,600 to €3,000 per month including payroll charges for a full-time position at or slightly above minimum wage. Add recruitment, holidays and absences to cover — and a structural limit: 35 hours a week, one call at a time.
- Human outsourced answering service: €300 to €1,500 (excl. VAT) per month depending on the formula (shared or dedicated agents), office hours, with +50 to +100% surcharges for evenings and weekends. All the models and rates are detailed in our guide to outsourced answering service pricing.
- AI phone assistant: €79 to €300 subscription + €0.20/min, available 24/7, multiple simultaneous calls, no night, weekend or public holiday surcharges.
Let's be honest: AI doesn't replace everything. Front-desk reception, emotionally sensitive situations, complex negotiations: humans keep the edge. The right question is not "AI or human", but "who handles the 80% of standard calls while the team works". That is the role of an AI phone secretary: filter, qualify, transfer the sensitive.
ROI: the math for an SMB missing 2–3 calls a day
An SMB missing 2 to 3 calls a day typically loses €1,000 to €1,500 of revenue per month — often more in high-ticket trades. The calculation, step by step:
- 1.Count your missed calls. 2 to 3 per working day means 45 to 65 per month. That is the order of magnitude observed in small businesses without a dedicated switchboard: calls during appointments, on job sites, over lunch, after 6 pm.
- 2.Estimate the share of new prospects. Roughly one missed call in three is a new request (quote, appointment, booking): 15 to 20 opportunities per month.
- 3.Apply the no-callback rate. Most callers leave no message and dial the next competitor. Even at a cautious 50%, that is 8 to 10 potential customers lost every month.
- 4.Multiply by your average ticket. At €150 of average customer value (less in hairdressing or restaurants, much more in trades, healthcare or real estate), the loss reaches €1,200 to €1,500 per month.

The 5 traps that inflate the bill
The advertised price is not always the price you pay. Here is what to check line by line before signing, whoever the vendor is.
- 1.Hidden setup fees. Some players charge €500 to €5,000 for "setup" or "initial configuration", sometimes only revealed at quote stage. Ask explicitly whether onboarding and adjustments are included.
- 2.Long-term commitment. 12 to 24 months imposed, with exit penalties. Read the termination terms before signing, and be wary of discounts tied to a long commitment on a technology you haven't tried yet.
- 3.Expensive out-of-bundle minutes. An "attractive" plan with a small bundle of included minutes can hide extra minutes at €0.50–1/min. Demand the exact per-minute price beyond the bundle and simulate your bill on your real volume.
- 4.Essential options... sold separately. Call transfer, confirmation SMS or email, calendar integration, a second language: check what is actually included in the base plan before comparing two offers.
- 5.No trial in real conditions. A recorded demo says nothing about how the agent behaves on YOUR calls, with YOUR customers and YOUR edge cases. Without a trial on your real traffic, you are buying blind.
How to test risk-free: the real-conditions trial
At Maia Solution, the process is built so that you never pay before seeing the agent work on your real calls.
- 1.V1 of your agent built in about a week. The agent is configured tailor-made: your opening hours, your services, your vocabulary, your transfer rules.
- 2.Testing on a dedicated number. You call the agent on a test number, push it to its limits, and we adjust: V2 and V3 versions are included, until you are satisfied.
- 3.One-week free trial on your real number. The agent answers your real customers, in real conditions, no credit card required. You follow every call in your dashboard.
- 4.Decision without pressure. You stop? We uninstall, you pay nothing. You continue? The subscription starts the following week — your choice: monthly with no commitment, or annual with a one-year commitment.

FAQ – AI phone assistant pricing
What is the average price of an AI phone assistant for an SMB?▼
For an SMB, expect €100 to €250 (excl. VAT) per month all-in with an off-the-shelf solution: a subscription of €79 to €300 depending on the plan, plus call minutes used (€0.15 to €0.30/min across the market, €0.20 at Maia Solution). Custom enterprise solutions sit between €2,000 and €10,000 per month and target large accounts; custom development starts at €15,000–50,000 upfront. For 95% of small businesses, the first category covers all everyday needs: appointment booking, qualified messages, answers to frequent questions, urgent call transfers.
How is an AI voice agent billed?▼
The dominant model in 2026 is monthly subscription + per-minute call billing. The subscription covers the platform, configuration and support; the minutes reflect actual usage. Example: 200 calls/month averaging 2.5 minutes = 500 minutes; with a €79 plan and €0.20/min, the total bill is €179 (excl. VAT). The advantage of this model: your cost follows your actual activity, without paying for an idle front desk. Always check the per-minute price beyond any included bundle: that is where some offers get expensive.
Are there setup fees?▼
It depends on the category. In the enterprise segment, setup fees run into thousands of euros and deployment takes months. In the off-the-shelf SMB segment, configuration is generally included in the subscription — that is the case at Maia Solution: building V1 of the agent (about a week), V2/V3 adjustments until you are satisfied, and going live on your number are all included, with no setup fees. If a vendor in this category charges you a hefty setup fee, ask exactly what it covers.
Is an AI assistant really cheaper than a receptionist?▼
On raw cost, yes, by far: a full-time salaried receptionist costs €2,600 to €3,000 per month including payroll charges, versus €100 to €250 (excl. VAT) for an AI assistant — a 10-to-20 ratio. But the fairest comparison is about scope: the receptionist works 35 hours a week and handles one call at a time; the AI answers 24/7, manages several simultaneous calls, and takes neither holidays nor sick leave. On the other hand, humans remain superior for front-desk reception and emotionally delicate situations. Many SMBs combine both: the AI takes standard calls and overflow, the team keeps the high-value conversations.
Do I have to commit long-term?▼
It depends on the vendor: some impose 12 to 24 months of commitment, sometimes in exchange for a discount or waived setup fees — be careful if you haven't tried the solution yet. At Maia Solution, the subscription is your choice: monthly with no commitment, or annual with a one-year commitment (preferential rate). And in all cases, the one-week trial in real conditions is free, with no credit card and no commitment: if you stop at the end of the trial, the agent is uninstalled and nothing is billed.
How much do call minutes cost?▼
In the off-the-shelf market, a call minute sits between €0.15 and €0.30 (excl. VAT); Maia Solution bills €0.20/min whatever the volume. Beware of "all inclusive" offers with a minute cap: beyond it, extra minutes can climb to €0.50–1. To estimate your usage, count 2 to 3 minutes per handled call (appointment booking, qualified message). An SMB with 150 calls/month therefore uses roughly 300 to 450 minutes, i.e. €60 to €90 of variable cost at €0.20/min.
Conclusion: think total cost, not sticker price
There is no such thing as "the" price of an AI phone assistant: there are three categories of solutions, with a 1-to-100 spread. For an SMB in 2026, the relevant range is €79 to €300 (excl. VAT) of monthly subscription plus minutes used — in most cases, €100 to €250 per month all-in. That is 10 to 20 times less than a salaried receptionist, for 24/7 coverage that no human solution offers at this price.
Before signing anywhere: demand the total cost on your actual call volume, check setup fees, the out-of-bundle minute price and the commitment terms — and never pay before testing the agent on your real calls.
