The four pricing models for AI phone answering, effective cost per minute and per call, a side-by-side at 300, 600 and 1,000 calls, the hidden fees to check and how to size the minutes you need.
AI phone answering is priced three ways: flat monthly plans with included minutes, per-minute platform rates, and per-call managed services. Botcadence's Voice AI plan is $299 a month with 1,500 minutes and $35 per extra 200 minutes, about $0.60 per 3-minute call; live answering services bill per minute or per call and rise with volume. Work it out at your own call count on the AI voice agent page and pricing.
AI phone answering services are sold three ways: flat monthly plans with included minutes, per-minute platform pricing, and per-call managed services. Published vendor pages we reviewed in October 2026 put software plans for a small business between roughly $25 and $300 a month before overage, and live human answering services between roughly $100 and $1,000 or more a month depending on minutes. Botcadence's Voice AI plan is $299 a month with 1,500 minutes included and $35 per extra 200 minutes, and the Restoration 24/7 Answer Desk for restoration companies runs on that same plan. The right comparison is at your own call volume, so this guide shows how to work it out.
This guide covers managed answering services. For developer platforms such as Retell, Vapi and Bland, and a table at 500, 1,500 and 3,000 minutes, see the AI voice agent pricing guide.
| Model | How it works | Best for | Watch out for |
|---|---|---|---|
| Flat monthly plan | Fixed price with included minutes and a published overage rate | Predictable budgets, steady or seasonal volume | Overage once included minutes run out |
| Per-minute | You pay for connected minutes, often with separate telephony and AI model charges | Low or very variable volume | Add-on charges that are not in the headline rate |
| Per-call | A price per answered call, sometimes with a monthly bundle | Managed services, emergency lines | What counts as a call (spam, hang-ups, transfers) |
| Hybrid | A base fee plus per-minute or per-call usage | Human answering services | The base fee buys little; usage drives the bill |
Rather than quote numbers that go out of date, here is how the main options are structured, with the figures we publish ourselves:
| Option | Pricing model | Included | Overage | Setup |
|---|---|---|---|---|
| Botcadence Voice AI | Flat monthly, $299 | 1,500 minutes, Starter chat plus SMS | $35 per 200 minutes | None on self-serve plans |
| Developer voice platforms (Retell, Vapi) | Per minute | Platform minutes; telephony and model billed separately on some plans | Per minute | Engineering time |
| Live receptionist services (Smith.ai, Ruby, AnswerConnect) | Per call or minute bundles | A bundle of calls or minutes | Per call or per minute above the bundle | Varies |
Vendor pricing pages linked in the sources were checked in October 2026; confirm current rates before deciding.
Convert every plan to an effective rate at your average call length. At a 3-minute average call:
| Monthly calls | Minutes | Botcadence Voice AI | Live service at $1.25 a minute (illustrative) |
|---|---|---|---|
| 300 | 900 | $299 | $1,125 |
| 600 | 1,800 | $299 | $2,250 |
| 1,000 | 3,000 | $579 | $3,750 |
The live-service column uses an illustrative mid-range per-minute rate; plug in your own quote. The pattern holds at most rates: software is flat until you exceed the included minutes, and human answering rises with every minute.
For example, an HVAC company with 700 calls in a summer month at 3 minutes each needs 2,100 minutes: on Voice AI that is $299 plus three $35 packs, $404 for the month. The AI answering service for HVAC page has a calculator for this.
Price the service against the calls you currently miss, not against zero. If a business misses 10 calls a week, 40 percent of those would have booked and the average job is worth $350, that is roughly $6,000 a month of work going to whoever answered. Set the booking rate and job value from your own records; the point is that the plan price is small next to a single month of missed jobs for most service businesses.
Keep people on the line for clinical emergencies, high-emotion disputes and VIP accounts until scripts and escalation rules are proven, and for very low volumes where a bundle of 50 calls is cheaper than a flat software plan. Many businesses run a hybrid: the AI voice agent answers first, books what it can, and transfers the exceptions to a person with the transcript. See AI receptionist vs virtual receptionist vs answering service for when each fits.

Questions readers ask
Published software plans for small businesses run from roughly $25 to $300 a month before overage; Botcadence's Voice AI plan is $299 with 1,500 minutes included. Live human services typically cost more at the same volume because they bill per minute or per call.
Usually, once volume passes a few hundred calls a month: a flat software plan stays fixed until the included minutes run out, while receptionist bundles grow with every minute. At very low volume a small human bundle can be cheaper.
Flat plans win when volume is steady or seasonal and you want a predictable bill; per-minute pricing can win at very low or highly variable volume, but check for separate telephony and model charges that are not in the headline rate.
Check for setup fees, number porting, transfer minutes, premium voices or languages, SMS follow-ups, integration add-ons and annual contracts. Botcadence self-serve plans have no setup fee. On Botcadence's Voice AI plan, inbound and outbound calls both use the 1,500 included minutes, and extra minutes cost $35 per 200.
Botcadence's Free plan covers web chat and WhatsApp, not voice. Voice answering starts on the Voice AI plan at $299 a month; the live demo line on the AI voice agent page lets you hear it before paying.
