AI answering services are billed one of three ways: per minute, per call, or a flat monthly fee. Per-minute and per-call plans move with your call volume, so a busy month costs more. Flat plans don’t. Beside is flat at $29.99 a month, or $199.99 a year.
The gap between those sentences is where the confusion lives. Two services can advertise nearly the same headline number and hand you bills that differ several times over in the month you most wanted to have.
Why the prices you’ve seen don’t agree
Search this question and you will get a spread of different answers, all published this year, all confident. They disagree because they are answering a different question than yours: what the market charges, rather than what your line would cost.
So the useful move is not to collect more ranges. It is to learn the three shapes a bill can take, then apply them to your own line. And “starting at” tells you where the meter begins. It says nothing about where it stops.
The three ways answering gets billed
Look for the billing unit before you look at the number.
| Billing model | What you’re quoted | What moves your bill | What to check before you sign |
|---|---|---|---|
| Per minute, or a minute bundle | A monthly fee for a set number of included minutes | Minutes used above the bundle | Whether the overage rate is published at all |
| Per call | A price for each answered call | The number of calls | What counts as a call, including hang-ups and wrong numbers |
| Flat monthly (Beside) | One fee, one user, one line | Users and lines, not minutes | Coverage area, and whether a meter exists anywhere on the page |
Both of the pricing pages checked for this article sell minute bundles. One sells 250 minutes for $49 a month, 1,000 for $149 and 2,000 for $299 (Source: vendor pricing page, 2026). Another sells 200 minutes for $99 and bills $0.25 a minute beyond it (Source: vendor pricing page, 2026). Some services bill per answered call instead. If you meet one, the thing to ask for is the definition: what counts as a call.
What “flat” has to mean before you trust it
A flat fee is only worth anything if there is no meter behind it, so it is fair to ask what “unlimited” is hiding. Beside’s pricing page lists “unlimited calls and texts (US & CA)” and publishes no per-minute rate, no minute bundle, no overage line, no setup fee and no cap or fair-use threshold anywhere on it (Source: Beside pricing, 2026). That is what the page says rather than a number we can put behind it. Coverage is the US and Canada, and the page does not address international rates.
What changes your bill is people, not minutes. The $29.99 is per user, each user includes one phone line, extra lines are $4.99 a month, and a multi-seat team is quoted separately through Beside for Teams. A three-person shop is three seats, not one, and that is better said here than found at checkout.
Where the money hides in a metered plan
Three mechanics account for most of the distance between a headline price and an invoice, and all three are visible if you know to look.
The tier that includes no answering. One published page lists a $20 a month plan with zero voice minutes, where every answered minute is billed on top at $0.25 (Source: vendor pricing page, 2026). Run 135 minutes through it and the plan costs $53.75 by our math: $20, plus 135 minutes at $0.25. The headline was accurate and it was not the price.
The bundle you paid for and didn’t use. That $99 plan for 200 minutes is $99 at 40 minutes. Use 135 of them and the minutes you actually bought worked out to about $0.73 each ($99 ÷ 135), which is roughly three times the $0.25 quoted for the ones you didn’t.
The overage rate that isn’t published. The page selling 250-, 1,000- and 2,000-minute bundles publishes no rate for exceeding those minutes (Source: vendor pricing page, 2026). Whatever that number is, it isn’t on the page you are buying from, which means you cannot work out your own worst month before you sign.
The rate you are quoted is almost always the price of the minutes you did not buy. The minutes you did buy are priced by division, and nobody does that division for you.
Run your own numbers
The month this matters in is the good one. You finally get busy, the phone runs hot for four weeks, and the answering bill for that month lands higher than the bill for the slow month before it. That is the arithmetic worth doing before you sign, and no pricing page does it for you.
You need two figures, and both are on your phone right now. Open Recents, count the incoming calls from last month, then look at the duration on five of them and take the middle one. Say 45 calls at about three minutes, which is 135 minutes, and a busy month at 110 calls, which is 330. Use your own two numbers, not these.
| Normal month, 135 min | Busy month, 330 min | |
|---|---|---|
| $99 bundle, 200 min, $0.25/min over | $99.00 | $131.50 |
| $49 bundle, 250 min, overage unpublished | $49.00 | $49 plus an unpublished rate on 80 minutes |
| $20 plan, no included minutes, $0.25/min | $53.75 | $102.50 |
| Beside, flat (one user, one line) | $29.99 | $29.99 |
Beside is priced per user, so two seats is $59.98 in either month and three is $89.97; what does not change is that minutes never enter it. The rates come from the two published pricing pages linked above. The totals are ours: $99 plus 130 minutes at $0.25 is $131.50; 330 minutes at $0.25 plus $20 is $102.50; 135 at $0.25 plus $20 is $53.75.
Look at the second row. That busy month stays unknowable until the invoice arrives, which is a strange thing to agree to in advance.
What changes when you have a good month
Under per-minute and per-call billing, the thing being metered is the thing you are trying to grow. Twice the calls is twice the answering, and the invoice arrives because the month went well. A busy August is a rate rise you did not agree to.
Under a flat fee the bill sits where it was. That difference outweighs most of the feature lists on either page. If you want the value side of the arithmetic, what one missed call is worth is the other half of the question.
What you’re actually buying at each price
A $29.99 line and a $299 metered service are not the same product, and most comparisons put them in the same column anyway. Two different things get sold under the same name.
The first is answering that sits in front of your number: someone or something picks up, takes a message, and passes it to you. You are buying coverage of the moment, billed by how much you use.
The second is a business line that answers as you and keeps what happened on it. Beside is that shape: an AI receptionist for calls and texts, appointment booking, lead qualification, transcripts and summaries of every call, a daily AI recap, number porting, call forwarding and caller ID, and voice cloning and customization (Source: Beside pricing, 2026). It works 24/7 by default, with business hours you set (Source: Beside, 2026). The number is yours, and the record of the call stays where you work rather than arriving as a message slip.
The obvious question is what you give up at the lower number. Between one metered plan and another, most of the gap is the metering rather than the answering. The real alternative to both is a human service, where you are paying for a person on the line, and if that is what you want and the budget is there, buy that. If you want your own number answered around the clock and a record of what was said, the meter is not buying you anything.
Which of the two you want is a different decision from which vendor. If you are still on the vendor question, which AI receptionist to actually pick covers it, and if the number itself is the sticking point, moving your business number covers that.
How to read any pricing page in two minutes
Four questions, in this order, on whatever page you have open in the other tab:
- What is the billing unit: a minute, a call, or a month?
- Is the overage rate published anywhere on the page?
- Does the cheapest plan include any answering at all?
- What does this bill look like in my busiest month, not my average one?
On a metered plan those four take real work, and on one live pricing page the second has no answer. On a flat plan the first three collapse, because there is no meter to interrogate, and the answer to the fourth is that nothing happens.
