If you are asking how much does an AI receptionist cost, you are probably losing calls first. The phone rings while you are on a job, with a customer, or closed for the night — and the caller does not leave a message. They call the next business on the list. An AI receptionist answers that call every time, day or night, takes the details, and can book the appointment. In 2026, most small businesses pay somewhere between $100 and $600 a month for that coverage. The wide range is not random. It depends on how many minutes you use, what the system is asked to do, and whether you are paying for real setup and support or just software. This guide breaks the pricing down in plain English, so you can compare quotes without guessing.
What an AI receptionist actually costs, by plan type
Most pricing falls into three buckets. Basic answering plans, roughly $100 to $250 a month, cover the essentials: answer every call in your business name, take a message, screen out spam, and send you the notes by email or text. These plans usually include a set number of minutes — often 100 to 300 — and suit a business that misses a handful of calls a week. Booking plans, roughly $250 to $500 a month, do everything above plus the work that saves you time: checking your calendar, booking and rescheduling appointments, answering common questions about hours, prices, and services, and sending reminders. This is where most small service businesses land, because a receptionist who can only take messages still leaves you doing all the follow-up. At Sigma Design, our inbound AI call agents start at $300 a month for 500 minutes, with no setup fees — that is the middle of this range, with booking included.
Higher-volume plans, $500 a month and up, are for businesses taking calls all day: more minutes, multiple locations or departments, custom call flows, and integrations with the software you already use. Overage matters here. Most providers charge per extra minute once you pass your included amount — commonly $0.30 to $1.00 a minute. A fair plan states that rate up front and does not roll unused minutes into a confusing credit system. Ask two questions before you sign anything: how many minutes are included, and what does one extra minute cost? If a seller cannot answer both in one sentence, keep looking.
What you are really paying for — and what should never cost extra
The monthly price is not just for a robot voice. You are paying for the phone number and call handling, the setup that teaches the system your services, hours, and booking rules, the calendar connection, and a human checking that calls are being handled correctly. Good providers include a plain-English summary of every call, so you can see who called, what they wanted, and what was booked. That record is also how you catch problems early — a wrong price quoted once can be fixed the same day.
Watch for add-ons that should be basic. Charging extra to answer after hours defeats the whole purpose — nights and weekends are when human cover is most expensive and missed calls are most common. Charging a large setup fee is another warning sign for a small business. Real setup takes work, but for a standard small-business plan it should be modest or included; we charge no setup fees because a long contract plus a big upfront fee usually means the seller is worried you will leave. Also be careful with per-call pricing that looks cheap. A plan advertised at a few dollars per call can pass a busy month's cost without warning, while a flat monthly plan with a clear minute allowance is easy to budget. Finally, check the contract length. Month-to-month is the honest standard at this size. If a provider needs twelve months signed before proving it can answer your phone, that tells you something.
Compare the total honestly against the alternative. A part-time human receptionist, even at a modest hourly wage for limited hours, costs far more once you count payroll taxes, training, sick days, and turnover — and still cannot answer at 9pm on a Sunday. We did that full math in AI receptionist vs hiring a receptionist. The AI option is not better at everything: a trusted human who knows your regulars by name is hard to replace. The right question is narrower — for the calls you currently miss entirely, is $300 a month cheaper than the jobs those callers take elsewhere? For most service businesses, one saved job a month covers it.
How to choose the right size plan and avoid overpaying
Start by counting your missed calls for two weeks. Your phone bill or call log already shows them: calls after hours, calls during busy periods, and calls that rang out. If you miss five to ten real calls a week, a basic or mid-size plan is enough. If the phone is a main source of bookings — clinics, salons, trades, legal intake — start in the booking tier, because message-taking alone will not move the number that matters, which is appointments actually set. That is also why your Google Business Profile matters here: a clean profile sends you more ready-to-buy calls, and the receptionist makes sure none of them are wasted.
Then run a simple test in the first month. Check three things weekly: Did every call get answered? Were the notes accurate enough to act on without calling back to ask basics? Did bookings go into the right calendar slots? A good provider will adjust the script and rules with you in those first weeks — that tuning is part of what the monthly fee buys. If after a fair first month the system is still mangling names or booking wrong, the problem is the provider, not the technology, and a month-to-month plan lets you walk away.
Bottom line: in 2026, expect $100 to $250 a month for message-taking only, $250 to $500 for a receptionist that actually books, and more only when call volume or complexity truly demands it. Pay for answered calls and booked appointments, not for setup fees, after-hours surcharges, or a long contract. Get the minute count and the overage rate in writing, start month-to-month, and judge the first month by your call summaries. The cheapest plan is the one that stops good customers from reaching your competitor's phone instead of yours.
