Most AI receptionists are priced in one of three ways: a rate per minute of call time, a flat rate per call handled, or a monthly plan that bundles a set number of minutes. Per-minute pricing is the most common, and it is the model that scales most predictably with a small business's actual call volume.
The honest answer to "what will this cost me" is that it depends almost entirely on how many minutes your phone is actually busy — not on the sticker rate. A salon taking 40 calls a month that average two minutes each is buying something very different from a clinic taking 400. This article explains how to work out your own number instead of guessing from a pricing page.
The three pricing models
Per minute
You pay for connected call time, usually rounded to the second or to six-second increments. Nothing is charged when the phone is quiet. This suits businesses with uneven call patterns — most appointment-based businesses — because a slow February costs less than a busy December.
Per call
A flat fee each time the assistant answers, regardless of length. This is simple to forecast but punishes short calls: a ten-second "are you open today?" costs the same as a four-minute booking. If a large share of your calls are quick questions, per-call pricing tends to be the more expensive of the two.
Monthly plan with included minutes
A subscription bundles a minute allowance at a lower effective rate, with overage billed on top. The lower rate is real, but only if you reliably use the allowance. Buying 3,000 minutes and using 600 means your true cost per minute is five times the advertised one.
| Model | Best when | Watch out for |
|---|---|---|
| Per minute | Call volume is uneven or seasonal | Long, chatty calls add up |
| Per call | Calls are consistently long | Short calls cost the same as long ones |
| Monthly plan | Volume is high and steady | Paying for minutes you never use |
What actually drives the cost up
The advertised rate is rarely the whole bill. These are the line items worth asking about before you commit:
- Setup or onboarding fees. Some providers charge once to build your configuration; others include it.
- Minimum commitments. A monthly minimum quietly sets a price floor no matter how quiet your phone is.
- Overage rates. Minutes past your allowance are often billed well above the in-plan rate.
- Per-integration charges. Connecting a booking system or calendar is sometimes a paid add-on.
- Phone number and telephony costs. A new number, call forwarding, or transfers may be billed separately from the AI itself.
- Transfer time. If the assistant transfers a caller to a person, check whether that time is still metered.
Ask this before signing up
"For a month where I take 150 calls averaging 2 minutes, with 20 of those transferred to a human, what is my total bill?" A provider who cannot answer that in one number is a provider whose pricing you do not yet understand.
Working out whether it pays for itself
The useful comparison is not AI receptionist versus zero. It is AI receptionist versus what missed calls currently cost you. Here is the arithmetic, using figures you should replace with your own.
Suppose your average booked service is worth $80, and you miss 25 calls a month because the team is with clients. If even one in five of those callers would have booked, that is 5 bookings, or $400 of service revenue that walked. Against that, 25 recovered calls at two minutes each is 50 minutes of AI call time. Whether the maths works depends on your per-minute rate, but at typical rates this comparison is not close — the missed bookings dominate.
Two honest caveats. First, not every missed caller is lost: some call back, and some were never going to book. Use a conservative conversion assumption. Second, an assistant that mishandles calls can cost you more than it saves, which is why the ability to test it before routing live traffic matters more than a few cents per minute.
| Input | Example value | Where to get yours |
|---|---|---|
| Average service value | $80 | Your booking system reports |
| Missed calls per month | 25 | Phone carrier or call log |
| Share who would have booked | 20% | Be conservative |
| Revenue at stake | $400 / month | Multiply the three above |
Compared with a human receptionist
A part-time front desk hire is a fundamentally different purchase, and it is worth being clear about the trade. A person handles ambiguity, reads tone, and solves problems no script anticipates. What they cannot do is cover 168 hours a week, and their cost does not fall to near zero on a quiet Tuesday.
In practice most appointment-based businesses are not choosing between the two. They are choosing whether the hours nobody is at the desk — evenings, weekends, and the stretch when everyone is with a client — are covered by something or by voicemail.
What AutoCall Pro charges
AutoCall Pro bills per minute of call time, with prepaid credits and monthly plans available for higher volumes. Because rates and any current trial offer change, the live numbers are on the pricing page rather than repeated here where they would go stale. Creating an account does not require a credit card, so you can build and test an assistant before deciding.

Common questions
Is there a genuinely free AI receptionist?
Free tiers generally mean a small trial allowance rather than an ongoing free service, because every answered call costs the provider real telephony and model compute. Treat "free" as "enough minutes to evaluate it".
Does it cost more when the assistant transfers to a person?
Often yes — the call is usually still connected and still metered during and after the transfer. Ask specifically, because businesses that transfer a lot can be surprised.
What happens if my call volume spikes?
On per-minute pricing the bill scales with the spike, which is usually the right outcome since the spike is business. On a fixed plan you hit overage rates instead, so it is worth knowing what those are before your busy season rather than during it.
