Short answer: anywhere from "almost free plus a lot of your weekends" to a five-figure custom build. The long answer depends on which of three routes you take. Each one hides its real cost in a different place.
Here's the honest breakdown, including the parts vendors don't love to talk about.
What are the three ways to get an AI receptionist?
Every option on the market falls into one of three buckets: build it yourself on a no-code platform, subscribe to an off-the-shelf product, or have one custom-built for your business. Same idea, very different price shapes.
Route 1: DIY on a no-code platform
The voice-AI platforms underneath most products are surprisingly cheap to rent directly. You pay per minute of talk time plus a small monthly platform fee. For a typical service business, that raw usage often lands well under what you'd spend on coffee for the crew.
The catch isn't the subscription. It's you.
Someone has to write the prompts, wire the phone number, connect the calendar, test the edge cases, and fix it every time it mishandles a caller. That someone is you, at night, after running your actual business. And the quality ceiling is real: a DIY agent tends to sound fine on the happy path and fall apart the first time a caller interrupts, rambles, or has an emergency. If the phone is how you get paid, "mostly works" is an expensive place to live.
Route 2: off-the-shelf AI receptionist subscriptions
This is the biggest category: sign up online, pick a plan, and an AI answers your calls the same week. Pricing varies a lot by vendor, but most plans land in the low hundreds per month, usually with a cap on minutes or calls and overage charges past it.
Fast to start. Genuinely useful for some businesses. But know what you're buying:
- Template scripts. The agent reads roughly the same playbook for every company on the platform, with your business name swapped in. Callers can usually tell.
- Per-minute meters. The month your marketing works and call volume doubles is the month your bill does too. You end up rooting against your own phone ringing.
- Your business bends to their model. If their system doesn't support your booking rules, your two-tier pricing, or your on-call rotation, you simplify your operation to fit their software, not the other way around.
For a low-volume business that mostly needs messages taken, a subscription can be a fine deal. For a business where calls are jobs, the template is the tax.
Route 3: custom-built (what we do)
A custom build costs more upfront. No way around that. You're paying for someone to sit down, map how calls actually move through your business, and build an agent around your services, your prices, your booking rules, and your voice. Then test it against hundreds of realistic calls before it ever touches a real customer.
The trade is simple: higher first check, then a flat, predictable shape. Our builds are fixed-bid: one number, scoped up front, no hourly billing. No per-seat charges. No per-minute meter punishing you for a busy month. Most builds go live in 2–4 weeks.
Custom makes sense when the phone is your revenue engine and a template answering it badly costs more than the build ever will.
What actually drives the price?
Whoever builds it, four things move the number more than anything else:
- Call volume. More calls means more talk-time cost on any platform, and more edge cases the agent has to handle well.
- Integrations. An agent that just takes messages is cheap. One that books into your real calendar, writes to your CRM or field-service software, and texts your techs is a bigger build, and worth far more.
- Routing complexity."Take a message" is one rule. "Emergencies go to whoever's on call, commercial accounts go to Dave, everything else books itself" is a decision tree that has to be designed and tested.
- After-hours coverage. Nights, weekends, and holidays are where the highest-value calls land, and where escalation rules matter most. Getting that right takes real design work.
What does it cost to keep NOT answering?
This is the number that should sit next to every price quote. A missed call isn't neutral. It's a caller who had a problem, had their card out, and dialed the next company on the list.
Run your own numbers: missed calls per day, times your close rate, times your average ticket. For most service businesses the monthly exposure makes any receptionist option, human or AI, look cheap. We worked the full math, industry by industry, in what missed calls actually cost a service business.
The point isn't that AI is magic. It's that the status quo has a price too, and it's usually the biggest number on the page.
What's in a fixed-bid proposal from us?
If you book a call with us, here's what happens: a 30-minute discovery call where we map how calls flow through your business today: what gets missed, what gets booked, what drives you crazy. Then you get a written, fixed-price proposal.
One number covers:
- The agent, scripted in your voice and approved by you before we build
- Phone routing: keep your number, choose which calls the AI takes
- Calendar and CRM integration so booked means booked
- Testing against hundreds of realistic call scenarios before go-live
- Monitoring and tuning after launch, while it earns your trust
No meter, no seats, no surprise line items. If the number doesn't make sense against what missed calls are costing you, don't sign it. That math is the whole pitch. Book the call and get your number.
