Here's an overview of the cost for the leading AI answering services (ranked from cheapest to most expensive)
Introduction
AI-powered answering services offer round-the-clock assistance, minimizing missed chances and lowering expenses in comparison to conventional receptionists.
But how much does it cost?
Let’s break down the pricing models, cost ranges, and compare services.
What Is an AI Answering Service?
An AI answering service is an automated system that handles incoming calls for businesses, filtering spam, taking messages, forwarding important calls, and even transcribing conversations.
These services are popular among SMBs that need a professional phone presence but don’t want to hire a full-time receptionist.
These services address both simple queries (like “what are you business hours?”) and intricate customer issues (“can I schedule an appointment?”), allowing your team to concentrate on strategic objectives and essential performance indicators.
How Much Does an AI Answering Service Cost?
There is no single answer to the question of phone answering service cost, as prices vary significantly based on several factors.
It usually boils down to two factors: call volume and features.
Elements That Affect the Cost
Call Volume
Call volume is by far the biggest predictor of cost, as most providers structure their pricing models based on the total number of minutes used or calls processed within a monthly billing cycle.
This is the case of the following AI receptionits:
- RingCentral: $49/month for 100 minutes. Extra minutes are charged $0.50 per minute.
- Sona: All plans include 10 calls. Above this limit, you can purchase credit packs. With the cheaper pack, you pay $0.75/call.
- Goodcall: Each plan includes a fixed number of unique callers and extra calls are charged $0.50/customer.
This usage-based approach allows businesses to align their communication expenses with actual activity levels, potentially offering cost advantages for organizations with predictable call patterns.
Companies with fluctuating call volumes should carefully analyze their historical communication data to select plans that accommodate both average usage and potential peak periods without incurring excessive overage charges.
Slang and Allo are the only two AI receptionists offering unlimited plans.
Additional Features
Some services like Rosie and Slang also charge more for advanced features.
For example, Rosie includes appointment scheduling only in their Scale and Growth plans.
Pricing Models of AI Answering Services
AI answering services typically follow one of these three pricing models.
Flat Monthly Fees
A fixed price for a set of users or numbers (e.g., $50/month, per user). This pricing model offers a simple monthly fee making it easy and transparent, allowing businesses to manage their communication expenses without worrying about fluctuating costs.
Allo illustrates this model with a fixed monthly fee for its AI powered answering service, giving you full cost predictability as your communication needs expand.
This model is pretty rare among AI answering services.
Usage-based plans
A lot of AI answering services offer usage-based plans that include a set number of call minutes or calls per month.
These plans are easy to understand and can reassure users who want to benefit from all the advanced features even if they don't receive a lot of calls. But they might prove too rigid when there are call spikes.
Smith.ai follows this model, for example, with the Starter plan including 50 calls, the Basic 150, and the Pro 500.
Hybrid Models
A combined pricing structure between a flat monthly fee and a pay-per-minute pricing structure. This approach typically includes a base monthly fee that covers a predetermined set of services or usage allowance, plus additional charges for the extra minutes or calls they make during that month.
This model can also complement additional charges like add-ons as specialized integrations with existing business systems, or access premium features beyond the standard package.
HeyRosie and Dialzara follow this pricing model.
Now let’s check how AI receptionists compare with traditional phone answering services in terms of cost.
Are AI Answering Services Cheaper Than Traditional Answering Services?
Traditional live answering services typically charge anywhere from $200 to $7000 per month for human receptionists who handle a limited number of incoming calls. These services employ actual people to answer phones on behalf of businesses, which accounts for the significantly higher price point due to labor costs, training requirements, and operational overhead.
AI answering services, on the other hand, can cost as little as $16/month (Allo) or $0.25 per minute (Rosie AI), making them a substantially more affordable and scalable option, especially for small and medium-sized businesses with budget constraints.

Top 5 Factors (Besides Price) to Choose the Best AI Answering Service
If you’re choosing an AI answering service, we recommend considering these factors beyond cost:
- Accuracy & AI Capabilities – Ask yourself, does the AI effectively transcribe conversations with high precision? Does it generate accurate, comprehensive summaries that capture all essential details and nuances? The system's ability to correctly interpret different accents, speaking styles, and industry terminology directly impacts its utility for business communications and decision-making processes.
- Spam filtering – The system efficiently identifies and blocks unwanted robocalls, telemarketing attempts, and other spam communications, helping to protect your time and maintain focus on legitimate business interactions.
- Integrations – The system's ability to seamlessly connect and synchronize with your existing business software ecosystem, including your CRM platform, your calendar, team messaging applications, and other essential productivity tools.
- Customization – The extent to which you can personalize the system to align with your specific business requirements by setting up custom greetings that reflect your brand voice, creating intelligent routing rules that direct calls to appropriate departments or individuals, and configuring flexible business hours that accommodate your operational schedule.
- Scalability – Will the system effectively accommodate your expanding business operations as you grow? A truly scalable solution should seamlessly adjust to increasing call volumes, support additional team members, and incorporate new features without requiring significant reconfiguration or causing performance degradation.
- Features set – Do you need a full phone system? Or do you prefer to keep your existing system? Do you need appointment booking? Summaries?
Conclusion
AI answering services offer a cost-effective alternative to human receptionists, with pricing starting as low as $16/month for basic plans and going up to $500+/month for premium features.
If the pricing if your main driver, we recommend the following options:

- For mid-sized businesses (100-500 calls/month) → Allo ($16/month) for unlimited calls or Rosie.
