Short answer: For most small businesses, an off-the-shelf AI receptionist costs about $29 to $500 per month, depending on how many calls or minutes you use. A custom-built AI receptionist adds a one-time build cost on top of usage fees, while a live human answering service starts around $250 per month for just 50 minutes. That is the real AI receptionist cost picture in 2026, based on public vendor pricing pages as of Oct 2026.
Almost every article ranking for AI receptionist cost is written by a company selling its own plan. This neutral guide compares public prices, runs the numbers for 100 and 300 calls a month, lists the hidden setup work, and shows when a part-time receptionist still makes more sense.
Prices below were checked on each vendor's public pricing page in October 2026. Vendors change plans often, so always check current pricing before you buy.
AI Receptionist Cost at a Glance (2026)
Here is what the most visible AI receptionist and answering service vendors publish on their own pricing pages. Ruby is included as a live human benchmark, since many owners compare an AI receptionist vs an answering service staffed by people.
| Vendor | How it bills | Entry plan | Mid plan | Notes |
|---|---|---|---|---|
| Dialzara | Per minute (bucket + overage) | $29/mo, 60 min | $99/mo, 220 min; $199/mo, 500 min | Overage $0.35 to $0.48/min; local number $3/mo; managed "Done for You" from $1,500/mo |
| Rosie | Per minute (bucket) | $49/mo, 250 min | $149/mo, 1,000 min | $299/mo plan with 2,000 min; calendar booking starts on the $149 plan |
| Goodcall | Per unique caller | $79/mo, 100 unique customers | $129/mo, 500 unique customers | No per-minute charges; extra customers billed at 15 to 79 cents |
| Smith.ai | Per call | Free, 25 calls | Pro from $150/mo (75 calls at $2.00/call) | Enterprise from $500/mo; live human backup available |
| Ruby (live humans) | Per minute (bucket) | $250/mo, 50 min | $395/mo, 100 min; $720/mo, 200 min | $1,725/mo for 500 min; human receptionists, not AI |
The spread in AI receptionist cost is wide because vendors measure usage differently. A per-minute plan rewards short calls. A per-call plan rewards long ones. A per-unique-caller plan rewards repeat callers. That is why the sticker price alone tells you very little.
How AI Receptionist Pricing Works
Per-minute plans
You buy a monthly bucket of talk time and pay overage when you go over. Dialzara and Rosie work this way. It is easy to budget if your calls are short and predictable.
Per-call plans
Smith.ai bills by the call, so a 30-second call and a 6-minute intake cost the same. That suits law firms and other businesses with longer qualifying calls. Smith.ai notes that spam it filters out does not count toward your quota.
Per-unique-caller plans
Goodcall counts unique phone numbers per month, so the same customer calling five times counts once. If you get lots of callbacks from the same people, this can be the cheapest option.
Managed or done-for-you plans
Some vendors offer a team that writes and tunes your call scripts for you. Dialzara's managed plan starts at $1,500 per month, and Smith.ai's Enterprise tier includes full-service setup.
AI Receptionist Cost per Month: 100 vs 300 Calls
To make the numbers comparable, we used one simple assumption: each call averages 3 minutes, and every caller is a different person. So 100 calls equals 300 minutes, and 300 calls equals 900 minutes. Swap in your own numbers.
| Option | 100 calls/mo (300 min) | 300 calls/mo (900 min) | How we got there |
|---|---|---|---|
| Dialzara | About $135 | About $349 | 100 calls: $99 Pro plan + 80 overage min at $0.45. 300 calls: $349 Elite plan (1,000 min). Add $3/mo for a local number. |
| Rosie | $149 | $149 | Both fit in the $149 Scale plan (1,000 min). The $49 plan's 250 min would not cover 300 min. |
| Goodcall | $79 | $129 | Starter covers 100 unique callers; Growth covers 500. |
| Smith.ai | About $213 | About $500 | 100 calls: Pro 75-call tier ($150) + 25 extra calls at $2.50. 300 calls: 300-call tier at about $1.67/call. |
| Ruby (live humans) | $1,725 | Custom quote | 300 min is more than the $720 plan's 200 min, so the next listed plan is 500 min for $1,725. 900 min is above the largest listed plan. |
| Part-time receptionist, 20 hrs/week | About $1,583 in wages | About $1,583 in wages | BLS median $18.27/hr x about 87 hrs/mo. Before payroll taxes and benefits. Covers only the hours they work. |
Two things stand out in this AI receptionist cost comparison. First, the AI receptionist cost per month stays fairly flat as volume grows, while a human service scales almost minute for minute. Second, the cheapest plan on paper is not always cheapest for you. If your calls average 8 minutes instead of 3, the per-minute plans jump and the per-call or per-caller plans start to win.
Off-the-Shelf vs Custom-Built AI Receptionist Cost
Everything above is an off-the-shelf tool: you sign up, connect a number, and fill in your business details. The other route is a custom-built voice agent wired into your own systems, which is the kind of project our AI agent development team builds.
| Off-the-shelf AI receptionist | Custom-built AI receptionist | |
|---|---|---|
| Upfront cost | Usually $0 (free trials are common) | One-time build cost. Our rough estimate: a few thousand dollars and up, depending on integrations |
| Monthly cost | $29 to $500 for most SMB plans (public pricing) | Usage-based. Our estimate: roughly $0.10 to $0.30 per minute in phone, speech and AI model fees, plus hosting and upkeep |
| Time to launch | Same day to a few days | Our estimate: several weeks |
| Integrations | Calendars, Zapier, popular CRMs | Your exact CRM, job software, pricing rules, multi-step workflows |
| Best for | Message taking, FAQs, simple booking | Complex intake, quoting, routing across locations, follow-up automation |
For most small businesses, start off-the-shelf. A custom build makes sense when the receptionist has to take real actions in systems that the packaged tools don't connect to, or when call volume is high enough that per-minute infrastructure costs come out lower than plan pricing.

The Hidden Setup Work Behind the Price
The monthly fee is only part of your total AI receptionist cost. What actually decides whether the tool pays off is the setup work, and that's mostly your time:
- Writing your knowledge base. Services, service area, hours, pricing rules and what the AI must never promise. Vague inputs cause confident wrong answers.
- Call routing and handoffs. Who gets urgent calls, what happens after hours, and how fast a caller can reach a human.
- Calendar and CRM connection. Booking only works if the tool can see real availability. Some plans gate this feature; Rosie, for example, includes direct calendar booking from its $149 plan.
- Phone number setup. Forwarding or porting your number, plus any number fees.
- Testing and weekly review. Listening to recordings and fixing gaps, especially in the first month.
If you would rather not do this yourself, factor in either your own hours or a managed plan. That is the real difference between a $99 tool and a $1,500 service.
AI Receptionist vs Answering Service vs Part-Time Receptionist
According to the U.S. Bureau of Labor Statistics, the median hourly wage for receptionists was $18.27 in May 2025, or $38,010 per year. A part-time receptionist working 20 hours a week costs about $1,583 a month in wages alone, before employer payroll taxes, paid time off or benefits.
That person also covers only 20 hours. An AI receptionist answers 24/7 and can take several calls at once, but it can't greet walk-ins, file paperwork or use judgment the way a trained person can. A live answering service like Ruby sits in between: real humans, higher per-minute cost.
Break-even math: AI receptionist cost vs revenue saved
Use this formula with your own numbers:
- Monthly cost of the plan / profit from one new customer = customers you need to win back each month to break even.
- Example only: if your plan costs $135 a month and one new job brings you $300 in profit, you need to save one job every two months to cover it.
- Compare that with how many calls you miss today. That is what the audit below is for.
Is an AI Receptionist Worth It?
What small business owners on Reddit say
We read through several Reddit threads where owners discussed this, including a 2026 r/smallbusiness thread on AI receptionists and an older r/smallbusiness thread titled "AI Answering Service - is it worth it?". The honest summary: opinions are mixed, and the positive ones are conditional.
- Owners who like it mostly use it for after-hours and overflow calls, simple FAQs and capturing caller details, not as a full receptionist replacement.
- Skeptics in service businesses with expensive leads say a clumsy bot can lose customers, and that a fast human callback or good voicemail is sometimes better.
- Common advice: tell callers up front that they're talking to an automated assistant, let them reach a human instantly, and keep the AI to facts it can't get wrong.
- One practical test from the 2026 thread: before you buy, ask the vendor for a real recording of a call ending in a confirmed booking on a live calendar, not just a demo.
Run a 2-week missed-call audit first
Before spending anything, measure the problem. For two weeks:
- Pull your missed-call and voicemail log from your phone system or carrier each day.
- Note the time of each missed call: business hours, lunch, after hours or weekend.
- Call each one back and tag it: new lead, existing customer, vendor or spam.
- Count how many were real new leads and estimate what they were worth to you.
If you miss only a few real leads a month and you can call back within minutes, a better voicemail may be enough. If you miss real leads every week, especially after hours, an AI answering service for small business is likely worth testing.
When NOT to use an AI receptionist
- Most of your calls are emotional, sensitive or need professional judgment.
- Your callers expect a personal relationship with a specific person.
- You can't commit time to set it up and review calls in the first month.
- You have very few calls and already answer almost all of them.
- You need it to quote complex prices or give technical advice it can't verify.
How to Choose an AI Answering Service for Small Business
- Match the billing model to your calls: short calls favor per-minute plans, long calls favor per-call plans, repeat callers favor per-caller plans.
- Check whether booking, warm transfers and bilingual answering are included in the plan you're pricing.
- Confirm you can keep your existing number and cancel month to month.
- Test it with real scenarios before going live. Several vendors offer free trials or test calls.
- If you also want website chat, compare bundles; some vendors include it. Our guide to building an AI chatbot for your business covers that side.
FAQ: AI Receptionist Cost
How much does an AI receptionist cost per month?
Most off-the-shelf plans for small businesses cost $29 to $500 per month based on public pricing as of Oct 2026. Entry plans include roughly 60 to 250 minutes or 25 to 100 callers, and in our worked example, 100 to 300 calls a month came out between $79 and about $500 for AI plans.
What is the AI receptionist for small business cost compared to hiring someone?
A part-time receptionist at the BLS median wage of $18.27 an hour costs about $1,583 a month for 20 hours a week, before taxes and benefits. Most AI plans cost a fraction of that, but they cover phone calls only.
Is an AI receptionist cheaper than an answering service?
Usually, yes. Ruby's live receptionist plans start at $250 for 50 minutes, while AI plans with several hundred minutes start under $150. Live services still handle complex or sensitive calls better.
Are there hidden fees in AI receptionist cost?
Watch for overage rates, phone number fees, features locked to higher tiers (like booking or warm transfers) and your own setup time. Read the plan details, not just the headline price.
Is an AI receptionist worth it for a small business?
It's worth it when you miss real leads, especially after hours, and the plan costs less than the profit from the customers it saves. Run a two-week missed-call audit, then compare the AI receptionist cost with what those calls are worth.
