AI receptionist pricing is confusing on purpose. The $29/month headline looks great until you see the $0.48/minute overage rate. The $49 plan sounds affordable until you realize appointment booking costs $100 more per month. The flat-rate plan at $199 seems expensive until you realize a busy month would have cost $400 under a per-minute plan.
This guide covers every pricing model in use right now, what each one actually costs at real call volumes, and which one makes sense depending on how your business works.
AI receptionists use four pricing models: per-minute, per-call, flat rate unlimited, and monthly flat rate. Per-minute plans look cheap and get expensive fast during busy periods. Flat-rate plans cost more upfront but protect against seasonal spikes. Dialzara charges $0.48/minute in overages. AnswerForce charges $2/minute. Smith.ai charges $292.50 for just 30 calls. Dolfyn starts at $179/month. Always ask what a busy month costs, not just the base price -- and always ask whether the AI actually gets better over time or stays exactly the same as day one.
You pay for the exact minutes used. Sounds fair. In practice it punishes you during your busiest periods. A heat wave sends HVAC call volume through the roof. Storm season spikes roofing calls. Every one of those extra calls costs more per minute. Dialzara charges $0.48/minute in overages. AnswerForce charges $2/minute for human receptionists. VoiceNation starts at $50/month for 30 minutes. The math gets ugly fast for a high-volume service business.
Fixed cost per call regardless of how long the call lasts. Smith.ai charges $292.50 for 30 calls. Their AI tier starts at $97.50 for 30 calls. Goodcall charges per unique caller. This model works well if most of your calls are short and your volume is predictable and low. For a contractor getting 150+ calls per month it gets expensive quickly.
One monthly price regardless of call volume. NextPhone is $199/month unlimited. Allo starts at $25/month for their AI answering layer on top of their phone system. This model is the cleanest for businesses with seasonal spikes because your cost doesn't change when your call volume doubles. The trade-off is the base price is higher than per-minute plans look on paper.
One monthly price based on a plan that fits your call volume. Dolfyn starts at $179/month. The key difference from per-minute plans is that your cost is known before the month starts rather than calculated after. Every client Dolfyn has ever onboarded is still active -- partly because the product works, and partly because pricing never surprises anyone.
| Provider | Starting Price | Model | Pricing Clarity | Setup |
|---|---|---|---|---|
| Dolfyn | From $179/mo | Monthly flat rate | Known before going live | Done for you |
| NextPhone | $199/mo | Flat rate unlimited | Published, no overages | Self-serve |
| Smith.ai (AI) | $97.50/mo (30 calls) | Per-call | $3.25/call overage | Done for you |
| Smith.ai (human) | $292.50/mo (30 calls) | Per-call | $9.75/call overage | Done for you |
| AnswerForce | $279+/mo | Per-minute | $2/min overage | Done for you |
| Rosie AI | $49/mo | Per-minute ($0.25/min) | $0.25/min overage | Self-serve |
| Dialzara | $29/mo | Per-minute | $0.48/min overage | Self-serve |
| Goodcall | $59/mo | Per unique caller | Varies by usage | Self-serve |
| Allo | $25/mo | Flat rate (phone system) | Published, no overages | Self-serve |
| My AI Front Desk | $65/mo | Per-minute tiered | Varies by plan | Self-serve |
Before choosing any plan, model what it costs during your busiest month, not just a typical one. Per-minute pricing looks great on paper and falls apart in practice when call volume spikes.
Example: HVAC company during a heat wave
Normal month: 150 calls, 3 min average = 450 minutes
Busy month: 280 calls, 3 min average = 840 minutes
Dialzara ($29/mo, 100 min included, $0.48/min overage):
Normal month: $29 + (350 min x $0.48) = $197
Busy month: $29 + (740 min x $0.48) = $384
NextPhone ($199/mo unlimited): $199 either month
The $29 plan becomes the most expensive option exactly when your business needs answering most. That is the trap with per-minute pricing -- the headline rate is designed for a slow month.
A $29/month AI that handles calls incorrectly, routes leads to the wrong person, or gives outdated information costs more in lost jobs than the price difference between plans. That cost is invisible on your monthly statement. It shows up as leads that called back and said they went somewhere else, or jobs that never got booked, or customers who left a bad review because the AI fumbled something.
Most self-serve AI tools are static. You configure them once and they stay that way. If something changes in your business -- new services, new coverage area, seasonal pricing -- the agent keeps doing what it was told at setup unless you go back and fix it manually.
Dolfyn's daily human review catches these problems before they compound. Real people listen to calls every day and adjust the agent as things change. Every client that has ever come on board is still active. That consistency has nothing to do with contracts and everything to do with a system that keeps getting better rather than staying frozen at day one.
The cheapest plan is not always the lowest cost. When evaluating AI receptionist pricing, the right question is not which plan has the lowest monthly fee. It is which plan recovers the most calls at a cost that makes sense for your business.
Setup fees. Some providers charge $200-$500 to configure your agent. Dolfyn's setup is included. NextPhone's self-serve has no setup fee. Smith.ai and AnswerForce may charge for onboarding.
Feature gating. Rosie AI's $49 plan does not include appointment booking. That's the $149 plan. Goodcall's cheaper plans lock certain integrations behind higher tiers. Always confirm what's included at the price point you're evaluating.
Annual contract requirements. Some providers offer lower monthly rates in exchange for annual commitments paid upfront. My AI Front Desk's pricing drops significantly on annual billing. Read the cancellation terms before committing.
Integration costs. Some providers charge extra for CRM integration, calendar connection, or specific software. Dolfyn builds integrations as part of the setup. Dialzara uses Zapier for most integrations which has its own cost.
The effective monthly cost is what you pay after overages, feature add-ons, and integration fees. Always ask for the all-in number at your expected call volume before signing up for anything.
Low call volume, short calls, tight budget: per-minute or per-call plans work if your volume is genuinely low and predictable. Rosie at $49/month for a business getting 20-30 calls per week makes sense. Watch the overages.
Moderate to high volume, seasonal spikes: flat rate wins. NextPhone at $199/month unlimited means your busiest month costs the same as your slowest. For HVAC, roofing, pest control, and similar businesses with clear seasonal patterns, this matters.
Complex call flows, custom integrations, done-for-you: a managed service where the agent is built around your specific business. Dolfyn starts at $179/month and handles setup, daily oversight, and ongoing improvement. No configuration burden on your end.
Human-handled calls, commercial accounts, high-value relationships: human answering services like AnswerForce or Smith.ai's human tier. More expensive but justified when the quality of the first human interaction is worth paying for on most calls.
The price of the AI receptionist is almost never the right thing to optimize. The right thing to optimize is the cost per recovered lead.
A contractor missing 30 calls per week at $400 average job value and 35% conversion rate loses $4,200 per week in potential revenue. At $199/month, NextPhone costs $6.63 per day. Recovering two calls per week pays for it. At $179/month, Dolfyn costs $5.97 per day. The math resolves quickly regardless of which plan you're evaluating.
The question isn't which plan is cheapest. It's which plan captures enough calls to justify the cost. At contractor job values, that answer is almost always yes regardless of which tier you choose.
