Most businesses shopping for AI phone answering solutions run into the same problem: pricing pages that say “contact us for a quote” or list features without numbers. It’s frustrating — and it’s intentional. This post gives you the actual numbers, the factors that drive cost up or down, and a straight comparison between your main options.
The short version: 365agents pricing starts at $115/month for the Basic plan (500 pooled minutes) and goes up to $1,140/month for Enterprise (5,000 minutes), with $0.25/minute overage on all plans. Across the broader AI voice agent market, DIY developer platforms start near zero per month but require engineering work, while fully managed services run $300–$500+.
TL;DR: 365agents plans range from $115/month (Basic, 500 min) to $1,140/month (Enterprise, 5,000 min) with flat-rate pricing and $0.25/min overage. No contracts, cancel anytime. For comparison, live answering services cost $150–$400/month and a part-time receptionist runs $1,800–$2,500/month. 365agents’ Professional plan at $230/month covers 1,000 minutes — enough for most small service businesses.

What’s the Actual Price Range for AI Voice Agents?
365agents publishes its full pricing at 365agents.com/pricing. Here’s what the plans look like:
| Plan | Price | Pooled Minutes | Overage |
|---|---|---|---|
| Basic | $115/month | 500 min | $0.25/min |
| Professional | $230/month | 1,000 min | $0.25/min |
| Business | $460/month | 2,000 min | $0.25/min |
| Enterprise | $1,140/month | 5,000 min | $0.25/min |
All plans include 24/7 AI Receptionist, After-Hours Coverage, Website Voice Agent, Call Summaries, 3,000+ app integrations, and a free onboarding call. No contracts, no hidden fees, cancel anytime.
Here’s how 365agents compares against other categories in the market:
- DIY / developer platforms (Vapi, Retell AI, Bland AI): Usage-based, $0.05–$0.10 per minute. No monthly base fee or a small one. You build and maintain everything yourself.
- SMB-ready platforms (365agents): Flat monthly plans starting at $115/month. Configured for you with guided onboarding, no coding required.
- Done-for-you managed services: $300–$500+/month. An agency builds, hosts, and manages the agent on your behalf.
What Drives AI Voice Agent Cost Up (or Down)?
AI voice agent pricing isn’t arbitrary. Five specific factors account for most of the difference between a $115/month plan and a $1,140/month one at 365agents — and the differences between platforms are even wider. Understanding them lets you spot when you’re overpaying — and when a cheaper plan won’t actually cover what you need.
Per-Minute vs. Flat-Rate Billing
Per-minute pricing sounds cheaper until your call volume picks up. At $0.08 per minute, a business handling 500 minutes of calls per month pays $40 — reasonable. At 3,000 minutes, that’s $240, which exceeds many flat-rate plans. Flat-rate plans give you predictable costs. Per-minute plans suit very low-volume businesses or those testing the concept for the first time.
Concurrent Call Capacity
Most entry-level plans handle one or two simultaneous calls. That’s fine for low-traffic lines. But if you run ads, have seasonal spikes, or operate in a field where multiple calls arrive at once (HVAC emergencies, for example), you’ll need a plan that handles concurrent calls. Upgrading for this capacity is a common reason costs jump between tiers.
Integrations and CRM Connections
Connecting your AI agent to a CRM, scheduling tool, or practice management system adds complexity — and usually cost. Some platforms charge per integration. Others include common ones (Google Calendar, HubSpot) at no extra charge and charge for custom or niche tools. Always ask which integrations are included before signing up.
Custom Voice and Persona
Generic AI voices have improved significantly, but many businesses want a voice that matches their brand. Custom voice cloning — where the agent speaks in a specific voice you’ve recorded — adds $50–$150/month on most platforms, or a one-time setup fee. It’s optional, but it matters for brand consistency in client-facing businesses.
Outbound Calling
Inbound call answering is the base feature. Outbound calling — for appointment reminders, lead follow-ups, or reactivation campaigns — is usually an add-on or a higher-tier feature. If outbound is a priority, confirm it’s included and at what volume before committing to a plan.
365agents data: In our experience working with small service businesses, the two features that most reliably push clients from a base plan to a mid-tier plan are outbound calling and CRM integration. Businesses that only need inbound answering plus appointment booking almost always fit on a base or mid-level plan.
How Do the Main Options Actually Compare?
The table below compares the three main categories side by side. Pricing reflects publicly available data as of early 2026.
| Option | Monthly Cost | Setup Required | Who Builds It | Included Features | Best For |
|---|---|---|---|---|---|
| DIY (Vapi, Retell, Bland AI) | $0 base + $0.05–$0.10/min | High — requires developer | You (or a developer) | Usage-based minutes; you configure everything | Tech-savvy teams, agencies |
| 365agents | $115–$460/mo (flat rate) | Low — free onboarding included | 365agents team | Inbound answering, scheduling, lead capture, SMS, 3,000+ integrations | SMBs wanting a working system fast |
| Done-for-you managed service | $300–$500+/mo | None | Agency | Full build + management | Businesses with complex flows, hands-off preference |
| Live answering service | $150–$400/mo | Low | Human agents (outsourced) | Human answering during business hours | Businesses needing human touch at lower cost |
| Part-time receptionist | $1,800–$2,500/mo | Medium | You (hire + train) | Daytime coverage only | High-complexity call environments |

How Does AI Pricing Compare to a Live Answering Service?
Live answering services typically cost $150–$400 per month for small business plans, according to pricing data from Ruby Receptionist and AnswerConnect (2024). That covers human agents answering calls during business hours and routing messages — but not after hours, not on weekends, and not with any CRM integration.
Key data: Live answering services for small businesses cost $150–$400 per month for basic plans, covering business-hours call answering and message taking (Ruby Receptionist pricing, 2024; AnswerConnect published rates, 2024). After-hours coverage and CRM integrations typically require higher tiers or add-on fees, pushing monthly costs toward $400–$600 for comparable feature sets.
AI voice agents run 24/7 by default. They don’t pass calls to voicemail at 5:01 PM. For businesses where after-hours leads matter — home services, real estate, healthcare — that availability difference often justifies the switch on its own. The math favors AI even at similar price points once you count the hours covered.
How Does AI Compare to Hiring a Part-Time Receptionist?
A part-time receptionist working 20 hours per week at $18–$20/hour costs roughly $1,800–$2,500 per month in wages alone, before payroll taxes and any benefits. According to the Bureau of Labor Statistics, the median hourly wage for receptionists in the U.S. was $18.70 in 2024. That’s a real person covering maybe 80 hours per month out of 720.
Key data: A part-time receptionist working 20 hours per week costs $1,800–$2,500/month in wages before employer payroll taxes (7.65% FICA) and benefits. The Bureau of Labor Statistics reported the median hourly wage for receptionists at $18.70 in 2024, meaning even a lean part-time hire runs roughly 10–15x the cost of a mid-tier AI voice agent plan.
[UNIQUE INSIGHT]: The comparison that rarely gets made: a part-time receptionist provides 80 hours of coverage per month. An AI voice agent provides 720. On a per-hour-covered basis, AI answering costs roughly 2–5 cents per hour. A part-time receptionist costs $22–$31 per hour. The ROI math isn’t even close — the question is whether your calls require human judgment, not whether AI is affordable.
What Are the Hidden Costs You Should Watch For?
The advertised price is rarely the final price. These are the line items that surprise business owners after they’ve signed up.
Setup fees. Some platforms charge $200–$500 to build and configure your agent. Others include setup as part of onboarding. Ask explicitly before signing.
Overage rates. Flat-rate plans often include a defined call volume or minute cap. Going over that cap triggers per-minute overage charges — sometimes at $0.10–$0.15/minute, which is higher than the per-minute rate on DIY platforms. Know your cap before you need to know it.
Per-integration charges. Connecting to Salesforce, a niche scheduling tool, or a custom CRM often costs extra. Platforms with “open integrations” may still charge for implementation time.
Voice and language add-ons. Spanish-language support, custom voice cloning, and premium voice models are commonly gated behind higher tiers or add-on fees.
Contract lock-ins. Month-to-month pricing usually runs 15–25% higher than annual contracts. Annual contracts limit your ability to switch if the product doesn’t fit. Start month-to-month while you validate performance.
365agents data: We’ve seen businesses sign up for a base plan, then discover their call volume triggers overage charges at $0.25/minute — adding $50–$150/month on top of the base price. At 365agents, overage is $0.25/min across all plans. Know your typical monthly call minutes before choosing a tier, and build in a buffer. Most small service businesses average 300–600 minutes per month.
Does the ROI Actually Work Out?
The ROI case for AI voice agents rests on one core assumption: your phone is a revenue channel, not just a support line. If that’s true, the math is usually clear.
Research from BIA Advisory Services found that phone calls convert to customers at 10–15x the rate of web form leads (BIA Advisory Services, 2023). A small service business that misses 5 calls per week and converts just 10% of those is losing roughly 2 new customers per month to missed calls alone.
Key data: Phone calls convert to paying customers at 10–15x the rate of web-form leads, according to BIA Advisory Services (2023). For a small business with an average transaction value of $300–$500, capturing just 2 additional leads per month that would otherwise go to voicemail produces $600–$1,000 in monthly revenue — enough to cover the cost of most AI voice agent plans several times over.
If your average job or transaction is worth $300–$500, capturing two extra leads per month pays for most mid-tier AI voice plans entirely. That’s the threshold. If you’re regularly missing calls — especially after hours — the question isn’t whether you can afford an AI agent. It’s how much you’ve already lost without one.
FAQ
How much does an AI voice agent cost per month for a small business?
365agents plans start at $115/month (Basic, 500 pooled minutes). Most small service businesses — dental offices, real estate agents, home services, law firms — fit comfortably on the Professional plan at $230/month, which includes 1,000 minutes. Higher-volume operations or multi-location businesses typically step up to Business at $460/month for 2,000 minutes. All plans include the same feature set with $0.25/min overage. See the full breakdown at 365agents.com/pricing.
What’s the difference between per-minute and flat-rate pricing?
Per-minute pricing charges you only for call time used — typically $0.05–$0.10/minute on developer platforms like Vapi or Retell. Flat-rate pricing charges a fixed monthly fee regardless of volume, up to a set cap. Flat-rate works better when call volume is consistent and predictable. Per-minute suits very low-volume use cases or experimentation.
Are there AI voice agents with no setup fee?
Yes. Several SMB-focused platforms, including 365agents, include onboarding and configuration as part of the subscription. Managed agency services almost always charge a one-time setup fee of $200–$500. DIY platforms have no setup fee, but you’re doing the build yourself or hiring a developer.
Can an AI voice agent replace a live answering service entirely?
For most inbound call categories — appointment booking, FAQs, lead qualification, after-hours messages — yes. AI voice agents handle these faster and at lower cost. Where live answering services still hold an edge: highly emotional calls, complex multi-step escalations, and callers who strongly prefer speaking to a human. Smart escalation rules let you combine both.
Is there a free trial available?
Yes. 365agents offers a free trial with no credit card required, so you can test call quality, response accuracy, and integrations against your real call environment before committing to a paid plan. Testing before signing is always the right call — no pun intended.
The Bottom Line
AI voice agent pricing isn’t one number. It’s a range that spans from nearly free (if you build it yourself) to $1,140/month at the enterprise tier. For 365agents specifically, most small businesses land on the Professional plan at $230/month — and at that price point, capturing even one or two additional leads per month typically covers the cost entirely.
The hidden-cost traps are real: overage rates, per-integration fees, and annual contract lock-ins can push your effective price well above the advertised plan. Read the fine print, start month-to-month, and test before committing.
If you’re comparing AI to a live answering service or a part-time receptionist, the math almost always favors AI on coverage hours and cost per lead. The question is whether your call mix requires human judgment — and for most small businesses, the answer is “only sometimes.”
