AI Receptionist Pricing Models Explained
AI receptionist pricing typically falls into three models: per-minute ($0.20-0.50/min), per-call ($3-11/call), or flat monthly ($29-300/month with included minutes).
Understanding how AI receptionist services charge can save you hundreds of dollars per month. The pricing model you choose matters as much as the price itself because your actual costs depend entirely on your call patterns. A busy plumber paying per-call will spend far more than one paying a flat monthly rate.
Which Trillet product is right for you?
Small businesses: Trillet AI Receptionist - 24/7 call answering starting at $29/month with 150 minutes included
Agencies: Trillet White-Label - Resell to clients starting at $99/month
What Are the Main AI Receptionist Pricing Models?
AI receptionists use three primary pricing structures, each with trade-offs depending on your call volume.
Per-Minute Pricing: You pay for actual talk time. Rates range from $0.20/minute (Trillet) to $0.48/minute (Dialzara overage). Best for businesses with unpredictable call volumes or shorter average call durations.
Per-Call Pricing: You pay a flat fee per call regardless of duration. Smith.ai charges $3.75-4.25 per call on their AI plans. This works well if your calls tend to be long (5+ minutes each) but becomes expensive with high call volumes.
Flat Monthly with Included Minutes: You pay a base subscription that includes a bucket of minutes, then pay overage for anything beyond. Trillet offers 150 minutes at $29/month, while Dialzara includes only 60 minutes at the same price point.
Pricing Model | Best For | Watch Out For |
Per-minute | Variable call volumes, short calls | High-volume months can spike costs |
Per-call | Long conversations, low volume | Expensive at scale |
Flat monthly + overage | Predictable volumes, budget planning | Overage rates vary widely |
How Much Does a Typical Small Business Pay?
Most small businesses spend $29-150/month on AI receptionist services, depending on call volume and chosen provider.
A business receiving 50 calls per month averaging 3 minutes each (150 total minutes) would pay:
Trillet: $29/month (150 minutes included, no overage)
Dialzara: $29 + $43.20 overage = $72.20/month (only 60 minutes included, 90 minutes at $0.48/min)
Smith.ai: $97.50/month for 30 calls, plus $127.50 for 20 additional calls at $4.25 = $225/month
Rosie: $49/month (unlimited minutes on Professional plan)
The difference between providers can exceed $150/month for the same call volume. Overage rates matter enormously: Trillet's $0.20/minute overage is 58% cheaper than Dialzara's $0.48/minute.
What Hidden Costs Should You Watch For?
Several costs can inflate your AI receptionist bill beyond the advertised price.
Setup fees: Some providers charge $50-200 for initial configuration. Trillet and most modern AI receptionists include setup free.
Per-feature charges: Call transfers, SMS notifications, and calendar integrations sometimes cost extra. Rosie locks CRM integration behind their $199/month plan. Trillet includes these features on all plans.
Minimum commitments: Annual contracts can lock you in at a rate that seemed good initially but prevents switching when better options appear.
HIPAA compliance: ChatDash charges $200/month extra for HIPAA compliance. Most small businesses do not need this, but medical practices and therapists should factor this into cost comparisons.
Unique customer caps: Goodcall charges $0.50 per unique customer over your plan limit, which can create unpredictable bills if you get an influx of new callers during a marketing campaign.
How Do You Calculate Your Actual Monthly Cost?
Calculate your expected cost by tracking your current call patterns for 2-4 weeks.
Count total incoming calls per week
Estimate average call duration (most business calls run 2-4 minutes)
Multiply to get monthly minutes
Compare against each provider's pricing structure
Example calculation for a dental office:
80 calls/month
3.5 minutes average
280 total minutes needed
Provider | Monthly Cost |
Trillet ($29 + 130 min overage at $0.20) | $55 |
Dialzara ($99 plan with 220 min + 60 min overage at $0.48) | $127.80 |
Smith.ai (90 calls at $4/call average) | $360+ |
The same call volume costs anywhere from $55 to $360+ depending on provider and pricing model.
Should You Choose Unlimited Plans?
Unlimited minute plans like Rosie's $49/month Professional tier sound attractive but come with trade-offs.
Pros of unlimited:
Predictable monthly costs
No anxiety about call spikes
Simple budgeting
Cons of unlimited:
Often lacks features available on tiered plans
May have hidden caps on unique callers or calls per day
Usually excludes premium features like call transfers or calendar booking
Rosie's unlimited plan, for example, excludes appointment booking and call transfers. These features require upgrading to $99/month or higher. For most businesses, a tiered plan with generous included minutes offers better value than a feature-limited unlimited option.
Comparison: AI Receptionist Pricing by Provider
Provider | Entry Price | Included | Overage | Key Limitation |
Trillet | $29/month | 150 min | $0.20/min | None at this tier |
Dialzara | $29/month | 60 min | $0.48/min | No API access |
My AI Front Desk | $65/month | Per-minute | Varies | No HIPAA compliance |
Smith.ai | $97.50/month | 30 calls | $4.25/call | Per-call adds up fast |
Rosie | $49/month | Unlimited | N/A | No booking on base plan |
Goodcall | $59/month | 100 unique customers | $0.50/customer | Customer caps, not minutes |
Trillet offers the best value for businesses under 300 minutes/month due to generous included minutes and low overage rates. For high-volume operations (500+ minutes), comparing total costs at your specific volume becomes essential.
Frequently Asked Questions
Which pricing model is best for a new business?
Start with a flat monthly plan that includes minutes, like Trillet's $29/month with 150 minutes. This gives predictable costs while you learn your actual call patterns. You can optimize later once you have 2-3 months of data.
Can I switch pricing plans if my call volume changes?
Most AI receptionist providers allow monthly plan changes. Avoid providers requiring annual commitments unless they offer significant discounts. Trillet allows plan changes at any time with no penalties.
Which Trillet product should I choose?
If you are a small business owner looking for AI call answering, start with Trillet AI Receptionist at $29/month. If you are an agency wanting to resell voice AI to clients, explore Trillet White-Label with Studio at $99/month (up to 3 sub-accounts) or Agency at $299/month (unlimited).
Do AI receptionists charge for spam calls?
Most AI receptionists charge for all answered calls, including spam. Trillet includes spam detection to minimize wasted minutes. Some providers offer voicemail-only mode for suspected spam, reducing costs from junk calls.
Is per-minute or per-call pricing better for long conversations?
Per-call pricing favors long conversations. If your average call exceeds 5 minutes, per-call rates around $4 beat per-minute rates of $0.20+ (which would cost $1+ for a 5-minute call). However, most small business calls average 2-4 minutes, making per-minute pricing more economical for typical use.
Conclusion
AI receptionist pricing varies dramatically between providers, with the same call volume costing anywhere from $29 to $300+ monthly. The key factors are included minutes, overage rates, and whether features you need are included or cost extra. For most small businesses handling under 300 minutes monthly, Trillet's $29/month plan with 150 included minutes and $0.20/minute overage delivers the best combination of value and features.
