Best AI Receptionist for Plumbers (2026): An Honest Comparison
Four AI receptionist services for plumbers compared, with prices checked in November 2026. None are built for plumbing. What that means for you.
If you search “best AI receptionist for plumbers,” you get roundup posts that read like they were written by the companies they’re ranking. Most don’t tell you the billing unit. Some don’t tell you the price at all until you book a call.
Here are four AI receptionist companies, with prices checked at their own pricing pages in September and re-checked in November 2026 (nothing had changed), plus where Plumber Secretary fits in that lineup. None of the four below are built specifically for plumbing. That matters more than the price does, and it’s worth understanding before you pick one on cost alone.
The short answer: which AI receptionist fits your shop
- Fewer than about 25 calls a month: Smith.ai’s free tier is the cheapest way to try an AI receptionist.
- A few dozen calls a month, mostly short: a minutes-based plan like Rosie Scale ($149) or Dialzara Pro ($99) can work, as long as booking and transfers are included at that tier.
- A busy shop that can’t have a surprise bill: a flat monthly plan is easier to budget. Plumber Secretary’s System + AI Secretary plan is $149 a month and includes up to 100 AI call minutes, and it’s built for plumbing calls specifically.
- You also want chat, texting, and email handled in one tool: My AI Front Desk bundles all of them, but they share one pool of credits.
The rest of this page shows the pricing behind each of those, so you can check it against your own call log.
AI receptionist, AI answering service, or AI phone system?
The three terms get used for the same thing, so don’t let the label decide for you. An AI receptionist answers your calls, asks the questions you set, and passes the details along. An AI answering service is the same idea sold as a replacement for the human answering services plumbers used for decades. An AI phone system usually means the same software plus call routing and texting. What matters is what it does after it picks up: whether it books the job, transfers an emergency, and sends you a clear summary.
Rosie: general small-business receptionist, minute-based
Rosie publishes three plans on its own pricing page:
- Professional: $49 per month for 250 minutes
- Scale: $149 per month for 1,000 minutes, adds calendar booking and live call transfers
- Growth: $299 per month for 2,000 minutes, unlimited custom scenarios
The catch is the Professional tier. It doesn’t include calendar booking or live transfers, the two things a plumbing shop actually needs from an answering service. To get those, you’re on the $149 tier, not the $49 one advertised as the entry price.
Rosie is built for small businesses in general, not plumbing specifically. Its own marketing covers salons, law offices, and med spas alongside home services.
Smith.ai AI Receptionist: per-call, free tier available
Smith.ai runs two separate products: a human-staffed “Virtual Receptionist” line starting around $300 a month, and a distinct “AI Receptionist” product priced differently. The AI product is the relevant one here:
- Free: $0 per month for 25 calls, then $3.00 per additional call
- Pro: $150 per month for 75 to 300 calls depending on volume tier
- Enterprise: $500 per month for 300 to 1,000+ calls
The free tier is real, which is unusual in this category. Twenty-five calls a month is roughly one every business day. A plumbing shop with any real call volume, especially during an emergency rush, clears that fast and lands on the $3.00 per-call overage.
Smith.ai is a general-purpose product used across legal, medical, and home service businesses. It isn’t trained on plumbing-specific intake, which is the gap why most AI answering services fail plumbers goes through in detail.
Dialzara: cheapest sticker price, tightest minute caps
Dialzara has the lowest advertised entry price of the four:
- Business Lite: $29 per month for 60 minutes, then $0.48 per minute
- Business Pro: $99 per month for 220 minutes
- Business Plus: $199 per month for 500 minutes
- Business Elite: $349 per month for 1,000 minutes, then $0.35 per minute
Sixty minutes sounds like a lot until you count real plumbing calls. A burst-pipe call that covers the problem, the address, access details, and scheduling can run several minutes on its own. At $29 a month, a handful of real calls uses the whole allowance, and every call after that costs $0.48 a minute regardless of what it’s about.
My AI Front Desk (Frontdesk): bundled channels, credit-based
Frontdesk’s Business-in-a-Box plan is $99 per month, or $79 billed annually:
- 200 voice minutes per month
- 100 chatbot conversations, 400 SMS messages, 500 email drafts, 300 web form submissions
- Everything beyond that draws from a shared pool of overage credits
This is the widest feature bundle of the four. It’s also the hardest to price against your actual usage, because voice, chat, SMS, and email all draw from the same credit pool at different rates. A busy month on any one channel can burn through credits meant for the others.
The pattern across all four
None of these four companies are built for plumbing. They’re general small-business receptionist products that plumbing shops happen to use. That shows up in two places: the billing unit, and what the AI actually knows how to ask.
A generic script doesn’t know that a customer describing a hissing sound near a water heater might mean a gas leak, or that “no hot water” and “no water at all” are two different urgency levels. Why most AI answering services fail plumbers covers what happens when a general-purpose bot takes a plumbing emergency call. For the billing side specifically, what an AI receptionist costs a small business breaks down per-minute, per-call, and flat pricing models in more depth than there’s room for here.
Side by side
| Company | Starting price | What you get for it | Billing meter | Built for plumbing? |
|---|---|---|---|---|
| Rosie | $49/mo (Professional) | No booking or live transfer until $149/mo tier | Minutes | No, general small business |
| Smith.ai AI Receptionist | $0/mo (25 calls) | Free tier real, then $150/mo for up to 300 calls | Calls | No, general small business |
| Dialzara | $29/mo (60 min) | Cheapest sticker price, tightest allowance | Minutes | No, general small business |
| My AI Front Desk | $99/mo ($79 annual) | Widest channel bundle, shared credit pool | Credits across voice/chat/SMS/email | No, general small business |
| Plumber Secretary | $149/mo (System + AI Secretary) | 24/7 answering, booking, and emergency triage; $95/mo Professional System has no AI answering | Flat monthly, up to 100 AI call minutes included | Yes, plumbing only |
Where Plumber Secretary fits
Plumber Secretary has two plans, and every plan has a 15-day free trial and no contracts:
- Professional System: $95 per month. Leads and job pipeline, scheduling and online booking, invoices and payments from your phone, one inbox for calls, texts, emails and web forms, and automatic Google review requests. No AI call answering.
- System + AI Secretary: $149 per month. Everything in the Professional System, plus a professional website built for you, Bella answering your calls 24/7, emergency triage and instant alerts, booking straight onto your calendar, call summaries by text and email, and up to 100 AI call minutes per month. It works with your existing phone number.
Add-ons on any plan: a business phone line with missed-call text-back is $29 per month, AI Secretary Starter (100 minutes) is $99 per month, and AI Secretary Pro (more minutes for busy shops) is $179 per month.
Bella is trained specifically on plumbing calls: burst pipes, sewage backups, gas smells, no water versus no hot water, the calls that actually come into a plumbing shop’s phone. You can hear her take a real call at (669) 284-5564.
That doesn’t make Plumber Secretary the right fit for every shop. If most of your calls are short and infrequent, a per-call plan like Smith.ai’s free tier might genuinely cost less some months. What it does mean is that you’re not shopping the same product across all five rows in that table. Read the meter, not just the sticker price, and decide based on what a real month of your calls would actually cost on each plan.
Common questions about AI receptionists for plumbers
How much does an AI receptionist for a plumbing company cost? Published prices run from free (25 calls a month on Smith.ai) to $349 a month for the larger minute plans, and Plumber Secretary’s AI secretary plan is $149 a month with 100 AI call minutes included. The billing unit matters more than the headline price. What an AI receptionist costs a small business breaks that down.
Can an AI receptionist book plumbing jobs? Yes, if the plan includes calendar booking. Some vendors hold booking back for a higher tier, so check which plan includes it before you compare prices.
Will an AI receptionist handle a plumbing emergency? Only if it’s set up to recognize one. A burst pipe or a gas smell needs an instant alert and a transfer, not a message left for morning. What your answering service should actually do on emergency calls lists what to require.
Is an AI receptionist better than a human answering service? It answers every call at any hour without a per-minute human labor cost. A human service can handle odd situations better. The real math on a receptionist versus an answering service compares them in full.
Do I need a new phone number? Usually not. Most services work by forwarding your missed calls. Here’s how to forward your missed calls.
Before you sign anything
- Ask what counts as a billable minute or call, and whether wrong numbers and robocalls count against your allowance.
- Confirm booking and live transfer are included at the price you’re being quoted, not a tier above it.
- Ask whether the service has handled plumbing-specific intake before, or whether you’d be the one training it.
- Get the overage rate in writing before your first real month, not after the bill arrives.
- Run your own call log through the pricing, not the vendor’s example month.
Every price above was checked at the company’s own pricing page in September 2026 and re-checked in November 2026. These pages change. Confirm the current number before you sign anything.
