AI Receptionist Pricing Models Explained
AI receptionist pricing falls into five models as of June 2026: per-minute (Trillet, Dialzara, Phonely), per-call (AIRA, UpFirst), credit-based (Echowin), per-caller (Goodcall), and managed service with a human backstop (Smith.ai). Trillet uses the per-minute model: $49/month with 150 minutes included, then $0.20/minute overage. The model you pick matters as much as the headline price, because your real cost depends on whether you have many short calls, a few long ones, or unpredictable spikes. This article breaks down each model, shows the math at typical call volumes, and flags the hidden costs that turn a cheap plan into an expensive one.
A business owner who reads only the entry price walks into traps that are easy to avoid once you understand how each model charges. A busy plumber on a per-caller plan during a marketing push pays very differently from one on a flat per-minute plan, even at identical call volume.

What Are the Main AI Receptionist Pricing Models?
There are five pricing structures in the AI receptionist market as of June 2026, and each one bills a different unit: minutes, calls, credits, unique callers, or a flat managed fee. Knowing which unit a provider charges for tells you exactly when their plan gets expensive.
Per-minute pricing: You pay for actual talk time, usually a monthly base that includes a bucket of minutes plus an overage rate. Trillet charges $49/month for 150 minutes then $0.20/minute, Dialzara starts at $29/month for 60 minutes then $0.48/minute, and Phonely runs $50/month for 250 minutes then $0.25/minute. Best for short calls and variable volume, because you only pay for the seconds you use.
Per-call pricing: You pay a flat fee per call regardless of duration. AIRA charges per call (its $24.95/month Starter tier covers 30 calls, with overage at the same per-call rate) and UpFirst bills the same way. This favors long calls but punishes high call counts, since a 30-second wrong number costs the same as a 6-minute booking.
Credit-based pricing: You buy a monthly bundle of credits, and different actions burn different amounts. Echowin's $49.99/month plan includes 1,600 credits, which the company says works out to roughly 100 minutes of voice. Credits require mental math to translate into real call capacity, and they typically do not roll over.
Per-caller pricing: You pay by unique phone number, not minutes or calls. Goodcall starts at $79/month for 100 unique callers, then $0.50 per additional unique caller. A single caller who phones five times counts once, but a marketing campaign that drives 200 new numbers in a month blows past the cap fast.
Managed service with human backup: You pay a higher flat base plus a per-call or per-minute charge for a service that blends AI with live human agents. Smith.ai's AI receptionist plans start at $95/month, and its human-staffed receptionist plans start around $292.50/month with overage of $8.50 to $11.50 per call. Best for businesses that want a person on the line for complex calls and will pay for it.
Pricing Model | Example Providers | Best For | Watch Out For |
Per-minute | Trillet, Dialzara, Phonely | Variable volume, short calls | Overage rates vary 2x to 3x |
Per-call | AIRA, UpFirst | Long calls, low volume | Expensive at high call counts |
Credit-based | Echowin | Mixed voice and chat | Credits expire, hard to translate to minutes |
Per-caller | Goodcall | Repeat callers, stable volume | Marketing spikes blow past caps |
Managed service | Smith.ai | Complex calls needing humans | Highest base cost, per-call adds up |
How Much Does a Typical Small Business Pay?
Most small businesses pay between $49 and $100/month for AI receptionist coverage at typical volume, with the exact figure driven by the pricing model more than the provider. To compare apples to apples, take a business receiving 50 calls per month averaging 3 minutes each, which is 150 total minutes.
Trillet (per-minute): $49/month, since 150 minutes are included with no overage
Dialzara (per-minute): $29 base plus 90 overage minutes at $0.48 = $72.20/month, because only 60 minutes are included
Phonely (per-minute): $50/month, since its 250-minute plan covers 150 minutes with room to spare
AIRA (per-call): the $24.95 Starter tier covers 30 calls, so 50 calls means 20 calls of overage at the per-call rate, landing above the base
Echowin (credit-based): $49.99/month for roughly 100 minutes of credits, so 150 minutes would require buying extra credits
Goodcall (per-caller): $79/month if those 50 calls come from 100 or fewer unique numbers, regardless of minutes
The same 150-minute month ranges from $49 to over $79 depending purely on which unit the provider bills. Overage rates are where per-minute plans separate: Trillet's $0.20/minute is 58% cheaper than Dialzara's $0.48/minute and 20% cheaper than Phonely's $0.25/minute.

What Hidden Costs Should You Watch For?
Several charges can inflate your bill well beyond the advertised entry price, and they differ by pricing model. The most common are setup fees, per-feature add-ons, compliance surcharges, and the structural traps baked into per-call and per-caller billing.
Setup fees: Some providers charge for initial configuration. Trillet, AIRA, and Dialzara advertise no setup fee, but always confirm before signing.
Per-feature charges: Call transfers, SMS notifications, and calendar integrations sometimes cost extra. Dialzara, for example, adds its SMS agent at $19/month plus $0.05 per message and a website chatbot at $39/month on top of the voice plan. Trillet includes voice, SMS, and WhatsApp on every plan at no extra charge.
Compliance surcharges: HIPAA and similar certifications are frequently gated behind higher tiers or add-ons. Phonely, for instance, reserves HIPAA for its Enterprise tier via a signed BAA rather than including it. Trillet includes HIPAA, TCPA, ACMA, and GDPR compliance on all plans. Most small businesses do not need HIPAA, but medical and dental practices should factor it in.
Per-caller caps: Goodcall's $0.50 charge per unique caller over your plan limit creates unpredictable bills. A marketing campaign or seasonal rush that drives an influx of new phone numbers can push you past the cap quickly, since each new number counts whether they talk for ten seconds or ten minutes. The daily-cap version of this trap is covered in AI receptionist daily interaction limits.
Per-call rounding: With per-call providers like AIRA and UpFirst, every answered call counts the same, so a high volume of short calls (wrong numbers, hang-ups, spam) costs as much as substantive bookings. Per-minute plans charge those short calls fractions of a cent.
How Do You Calculate Your Actual Monthly Cost?
Calculate your expected cost by tracking your real call patterns for two to four weeks, then running them through each provider's billing unit. The steps are the same regardless of model, but the final math changes depending on whether you are counting minutes, calls, or callers.
Count total incoming calls per week, and note how many are unique phone numbers
Estimate average call duration (most business calls run 2 to 4 minutes)
Multiply to get monthly minutes and monthly calls
Run those figures through each provider's pricing model
Example calculation for a dental office receiving 80 calls per month at 3.5 minutes average, which is 280 total minutes:
Provider | Model | Monthly Cost |
Trillet | Per-minute: $49 + 130 overage min at $0.20 | $75 |
Phonely | Per-minute: $50 plan with 250 min + 30 overage at $0.25 | $57.50 |
Dialzara | Per-minute: $29 + 220 overage min at $0.48 | $134.60 |
Smith.ai | Managed AI plan, 80 calls at roughly $2.40/call | $192+ |
The same 280-minute month runs from $57.50 to nearly $200 depending on the model. Per-minute plans cluster at the low end for typical durations, while managed per-call services climb fast as call count rises. Run your own numbers against the cheapest AI phone answering service comparison before committing.
Should You Choose Unlimited Plans?
Be skeptical of unlimited claims, because most have quietly disappeared or hide caps elsewhere. As of June 2026, "unlimited minutes" offers have largely moved to either fixed minute tiers or per-caller caps that function as a different kind of ceiling.
Goodcall, for example, bundles unlimited minutes but caps unique callers, so the limit moves from talk time to the number of distinct people who call you. Per-call providers have no minute cap at all but charge for every call. The lesson is that "unlimited" almost always trades one constraint for another.
What to do: Identify which constraint a plan actually enforces (minutes, calls, or callers), then map it to your real usage. If you get a steady stream of repeat callers, a per-caller cap may never bite. If you run marketing campaigns that drive new numbers, that same cap is a liability. For most small businesses, a per-minute plan with generous included minutes and a low overage rate gives the most predictable bill, a point covered alongside setup and features in the complete AI receptionist guide for small businesses. The full anatomy of these offers is in the truth about unlimited AI receptionist minutes.
Comparison: AI Receptionist Pricing by Model and Provider
As of June 2026, here is how the major providers line up by pricing model, entry price, and the catch buyers most often miss. The pricing model column is the one to read first, since it predicts when each plan gets expensive.
Provider | Model | Entry Price | Included | Overage | Key Limitation |
Trillet | Per-minute | $49/month | 150 min | $0.20/min | None at this tier |
Dialzara | Per-minute | $29/month | 60 min | $0.48/min | Only 60 min, high overage |
Phonely | Per-minute | $50/month | 250 min | $0.25/min | HIPAA on Enterprise (BAA) |
AIRA | Per-call | $24.95/month | 30 calls | Same per-call rate | Short calls cost full price |
UpFirst | Per-call | $24.95/month | Per-call | Same per-call rate | No minute pooling |
Echowin | Credit-based | $49.99/month | ~100 min (1,600 credits) | $1 per 100 credits | Credits expire, no rollover |
Goodcall | Per-caller | $79/month | 100 unique callers | $0.50/caller | Caps callers, not minutes |
Smith.ai | Managed (AI + human) | $95/month | Per-call | $2.10 to $2.40/call | Per-call adds up fast |
Trillet offers the most predictable cost for businesses under 300 minutes per month thanks to generous included minutes and the lowest overage rate in the table. For high-volume operations above 500 minutes, run the math at your specific volume, since the gap between models widens sharply at the top end.
Frequently Asked Questions
Which pricing model is best for a new business?
A per-minute plan with included minutes, like Trillet's $49/month with 150 minutes, is the safest start for a new business. It gives a predictable floor while you learn your real call patterns, and the $0.20/minute overage means a surprise busy week costs cents per extra minute rather than a full per-call fee. You can switch models later once you have two to three months of data.
Is per-minute or per-call pricing better for long conversations?
Per-call pricing favors long conversations because you pay one flat fee no matter the duration. If your average call runs well past 10 minutes, a per-call rate can beat a per-minute one. But most small business calls average 2 to 4 minutes, where per-minute pricing wins. At 3 minutes, Trillet's $0.20/minute overage costs $0.60, far below a typical per-call fee.
How does credit-based pricing actually work?
Credit-based pricing, used by Echowin, gives you a monthly bundle of credits that different actions consume at different rates. Echowin's $49.99/month plan includes 1,600 credits, which the company estimates at roughly 100 minutes of voice. The downside is that credits do not roll over and require translating an abstract unit into real call capacity, so a high-volume month can quietly run you out mid-cycle.
What is a per-caller cap and why does it matter?
A per-caller cap limits how many unique phone numbers you can serve per month, regardless of how many minutes or calls they generate. Goodcall includes 100 unique callers on its $79/month plan, then charges $0.50 for each additional one. This matters because a marketing campaign or seasonal surge that drives new phone numbers can push you over the cap fast, even if total talk time stays low.
Do AI receptionists charge for spam calls?
Most AI receptionists charge for every answered call, including spam, which hits per-call models hardest since a 20-second telemarketer costs the same as a real booking. Trillet includes spam and telemarketer blocking to minimize wasted minutes, and on a per-minute plan a brief spam call costs only a few cents rather than a full per-call fee.
Can I switch pricing plans if my call volume changes?
Most AI receptionist providers allow monthly plan changes, and Trillet lets you change plans at any time with no penalty. Avoid providers requiring annual commitments unless the discount is substantial, since locking in becomes a problem the moment your volume shifts or a better option appears.
Conclusion
AI receptionist pricing splits into five models as of June 2026, and the model you choose shapes your bill more than the headline price does. Per-minute plans (Trillet, Dialzara, Phonely) reward short calls and variable volume, per-call plans (AIRA, UpFirst) reward long calls, credit and per-caller models (Echowin, Goodcall) trade one cap for another, and managed services (Smith.ai) charge a premium for human backup. For most small businesses handling under 300 minutes per month, Trillet's per-minute plan at $49/month with 150 included minutes and $0.20/minute overage delivers the most predictable cost. As an example, a 200-minute month works out to $49 plus 50 overage minutes at $0.20, or $59 total.
