An AI receptionist for a contractor typically runs $20-$50/month as a software add-on, $50-$300+/month as a standalone AI voice agent once overages hit, or $300-$1,000+/month for a human-staffed answering service billed per call. Trusso's version is $29/mo for 100 minutes or $49/mo for 200, added to any plan — the only option tied directly to the contractor's own job and account data.
The confusing part isn't the sticker price. It's that almost every receptionist product — AI or human — quotes a low base rate, then bills the real cost somewhere else: per-minute overages, per-call fees, setup charges, or a separate phone number you now have to manage. A plan that looks like $39/month on the pricing page can land at $180/month once a busy week of calls comes in.
The Three Pricing Models You'll Run Into
Almost every receptionist product on the market falls into one of three buckets, and each one bills you differently when call volume spikes.
- Per-minute AI voice agents. A base monthly fee buys a block of minutes (often 100-300), then every minute past that is billed individually — usually $0.30 to $1.00+ per minute. A slow month costs almost nothing; a month with a marketing push or a seasonal rush can double or triple the bill.
- Per-call human answering services. You're paying for a live person, so pricing is usually quote-based and scales with call volume — commonly landing in the $300-$1,000+/month range once you account for a realistic number of monthly calls plus overage minutes.
- Flat add-ons bundled into software you already use. A fixed monthly price for a set number of minutes, billed on top of a platform the contractor is already running their business from, with no separate phone system to manage. Trusso's AI Receptionist add-on works this way.
| Option | Best for | Starting price |
|---|---|---|
| Trusso AI Receptionist | Contractors who want callers to get real answers about their own job, not just a message taken | $29/mo add-on for 100 minutes |
| Generic AI voice agents | Businesses that just need missed calls answered with a basic script | ~$50-$150/mo base, then $0.30-$1.00+/min overage |
| Human-staffed answering services | Businesses that want a live voice on every call regardless of cost | Quote-based, often $300-$1,000+/mo |
| Voicemail-to-text apps | A true solo operator who just wants a text summary of missed calls | Free-$15/mo, no live answering |
Trusso AI Receptionist
Best for: contractors who want a missed call to end in a booked lead or a resolved customer question, not a voicemail nobody checks until lunch.
What stands out is that it isn't a voice bolted onto a script. It's connected to the contractor's actual Trusso account, so it knows their services, hours, service area, and policies — and once a caller verifies their name and address, it can tell them their own appointment time, job status, estimate, or invoice balance, and resend documents to contacts already on file. New callers get captured as leads instead of falling through. It keeps the contractor's existing number through conditional call forwarding, so nothing changes on the business card or Google listing.
The honest limitation: it's an add-on to Trusso, not a standalone phone system, so it makes the most sense for contractors who want one place for calls, schedules, estimates, and invoices rather than a separate vendor to manage. It also won't quote a price the contractor hasn't published, and it never edits a schedule, invoice, or payment — if a request falls outside what it's authorized to do, it takes a callback message instead of guessing.
Pricing: $29/mo for 100 call minutes or $49/mo for 200, added to any Trusso plan ($29, $59, or $99/mo flat, no per-user fees). Recharge packs are $15 for 50 extra minutes and roll over month to month, so a busy month doesn't reset to zero. Details are on the AI Receptionist page.
Generic AI Voice Agents
Best for: a business that just needs missed calls answered with a scripted flow and doesn't need the agent to know anything specific about a caller's job.
These are fast to set up and usually phone-system agnostic, which is their main selling point. The tradeoff is that most are genuinely disconnected from the contractor's actual operations — they can take a message or answer FAQs from a script, but they can't tell a customer when their crew is arriving or what they still owe, because they were never given access to that data in the first place.
Pricing is where the base rate stops telling the whole story. A $50-$150/month plan usually buys a modest bucket of minutes, and every minute past that is billed separately, often $0.30-$1.00 or more. Contractors who get a seasonal spike in calls — storm damage, a holiday promo, a good month on Angi — can watch the bill double without changing anything about how they use the service.
Human-Staffed Answering Services
Best for: a business that wants a live human voice on every single call and is willing to pay for it.
A real person answering the phone handles nuance an AI script can't — an upset customer, an unusual question, a complicated scheduling ask. That's the entire value proposition, and for some businesses it's worth it.
The limitation is cost and ceiling. Published pricing is usually quote-based and scales with call volume, commonly landing in the $300-$1,000+/month range for a contractor getting a realistic number of monthly calls. And unless the service is manually fed a calendar and account updates by the contractor's office staff, the human agent still can't see the schedule or invoices — they're taking a message and promising a callback, the same outcome voicemail gives you, just with a friendlier voice and a much bigger bill.
Voicemail-to-Text / Call Transcription Apps
Best for: a solo operator on a tight budget who just wants missed calls turned into a readable text summary.
These are cheap or free and require no setup, which is appealing when cash flow is tight. But they don't actually answer the phone. The caller still hears a voicemail greeting, doesn't get told anything about the business, and — critically — has already had the chance to hang up and call the next name on their list before the transcription ever reaches the contractor's phone.
Pricing: typically free to $15/month, often bundled into a carrier feature or a basic app, but it's a convenience tool, not a receptionist.
What a Missed Call Actually Costs, Compared to Any of This
Every option on this list costs money. The number that actually matters is what happens when nobody answers at all. A missed call from a new lead doesn't usually result in a voicemail and a callback — it results in the caller dialing the next contractor on the list, and the real cost of those missed calls adds up to thousands of dollars a year in jobs that never made it to an estimate. Against that backdrop, even the most expensive answering service on this list is cheap. The real question isn't whether to pay for something — it's whether what you're paying for actually resolves the call or just defers it.
Why the Account Connection Changes the Math
The gap between a generic AI voice agent and one connected to the contractor's own business data is bigger than it looks on a pricing page. A script can greet a caller and take a message. A receptionist tied into the contractor's actual schedule, estimates, and invoices can tell a verified existing customer their appointment time, confirm a job is still on for Thursday, or resend an invoice they lost — the kind of call that used to require someone stepping off a ladder to answer. A closer look at AI receptionists versus human answering services breaks down that tradeoff in more depth if you're weighing the two head to head.
This is also why price-per-minute isn't the only number worth comparing. A cheaper service that only takes messages still leaves the contractor (or the office manager) doing the actual follow-up work by hand. A service connected to the business's real data resolves more of those calls without anyone picking up a phone.
The Bottom Line
If the goal is just to stop a phone from ringing into voicemail, a generic AI voice agent or a cheap transcription app will do that for not much money. If the goal is to stop losing jobs and stop fielding the same "what time is my appointment" calls between job sites, the receptionist needs to actually know the business — the hours, the service area, the price book, and the schedule — not just answer in a pleasant voice. Trusso's AI Receptionist is built as an add-on specifically so it has that access from day one, at $29/mo for 100 minutes or $49/mo for 200, on top of any Trusso plan, with no contract and a 14-day free trial to see what it actually catches.
How much does an AI receptionist cost per month for a small contractor?
Most small contractors land between $29 and $150 per month, depending on call volume and whether the service is a software add-on (cheaper) or a standalone AI voice product billed with per-minute overages (more expensive once volume climbs). Trusso's add-on is $29/mo for 100 minutes or $49/mo for 200.
Do AI receptionists charge per minute or per call?
It varies by provider. Most AI voice agents bill a base rate for a bucket of minutes and charge per-minute overages beyond that. Human-staffed services more often bill per call or quote a volume-based monthly rate. Trusso bundles minutes into a flat add-on price with rollover recharge packs instead of per-minute overage billing.
Is a human answering service worth the extra cost over AI?
It depends on what you need resolved. A live person handles nuance well, but unless they're given real-time access to your schedule and invoices, they're still just taking a message — the same outcome as an AI receptionist, at a meaningfully higher price, commonly $300-$1,000+/month.
Can an AI receptionist replace a human receptionist for a small contractor?
For most one- to ten-person crews, yes, for the specific jobs a receptionist does most: answering missed calls, capturing new leads, and giving existing customers basic status updates. It can't make judgment calls outside its rules — a well-built one, like Trusso's, falls back to a callback message when a request is unclear rather than guessing.
Does Trusso's AI Receptionist require getting a new phone number?
No. It keeps your existing number using conditional call forwarding, so only the calls you miss get forwarded to the AI — you don't have to publish or switch to a new number.
