AI receptionist pricing is one of the most confusing categories in business software. The advertised number is almost never the number you'll actually pay for the features your business needs. There are plan tiers, minute limits, overage rates, per-feature gates, and seat restrictions, all of which interact in ways that can turn a "$49/month" tool into a "$199/month" reality.
This guide is the honest breakdown. No marketing spin, no vague "starting at" language. Just the actual structure of how AI receptionist pricing works.
How AI Receptionist Pricing Works
Unlike simple SaaS subscriptions where you pay a flat rate, most AI receptionist tools use a consumption-based model layered on top of a subscription fee. This is because every call uses real compute resources, voice processing, AI inference, calendar API calls, that have genuine costs.
The structure: you pay a monthly subscription to access the platform, and that subscription includes a set amount of call time (minutes) per month. When you exceed those minutes, you pay an additional per-minute rate.
The 3 Variables You Must Understand
Variable 1, Monthly Subscription Price
This is the base fee. For small businesses, this typically ranges from $29–$179/month for meaningful functionality. The entry-level plans at $19 to $29/month usually include only basic call answering, no booking, no SMS, no lead qualification.
Variable 2, Included Minutes Per Month
Every plan includes a set number of call minutes per month. 250 minutes handles roughly 50–80 calls. 700 minutes handles 140–230 calls. 1,500 minutes handles 300–500 calls. Match your expected volume to avoid consistent overages.
Variable 3, Overage Rate Per Minute
This is the most overlooked pricing variable. Rates vary from $0.18/minute to $0.40/minute or higher. In a busy month with 300 overage minutes, the difference between providers could be $60 or more.
Before signing up for any AI receptionist, calculate your busy-month minute usage and multiply by the overage rate. If that number regularly exceeds $30–$40 in overages, it's cheaper to upgrade to the next plan tier. Providers count on customers not doing this math.
Feature Tiers: What Changes at Each Level
| Feature | Entry ($29–$49/mo) | Mid ($79–$129/mo) | Upper ($149–$199/mo) |
|---|---|---|---|
| 24/7 call answering | Usually included | Included | Included |
| Custom greeting | Usually included | Included | Included |
| Spam filtering | Usually included | Included | Included |
| Appointment booking | Rarely included | Usually included | Included |
| SMS follow-up | Rarely included | Sometimes | Usually included |
| Lead qualification | Not included | Sometimes | Usually included |
| Warm call transfers | Not included | Sometimes | Usually included |
| AI training on docs | Limited or none | Limited | More extensive |
The takeaway: for a service business that needs booking, SMS, and lead qualification, the entry plan almost never covers the full use case. Zevaux's Growth plan at $99/month includes all five of the critical features.
How to Calculate Your Monthly Minute Needs
- Pull up your phone's call log for the last 30 days. Count all inbound calls.
- Estimate average call length. Salons: 2–3 min. Home services: 4–6 min. Medical/legal: 5–8 min.
- Multiply: total monthly calls × average length = estimated monthly minutes
- Add 25% buffer for variability and busy periods
- Compare to plan limits: 250 min (Starter), 700 min (Growth), 1,500 min (Pro)
Hidden Costs to Watch For
- Setup fees: Some providers charge $50–$200. Zevaux doesn't.
- Add-on feature costs: Some tools charge extra for SMS or additional phone numbers.
- Seat costs: If you need more team members than your plan includes, some providers charge per seat.
- Annual vs monthly: Many tools offer 10–20% discount for annual billing.
- Cancellation restrictions: Some providers require notice periods or charge cancellation fees.
