How Much Does an AI Answering Service Cost for a Small Business?

Expect to pay anywhere from $0 to $500+ a month for phone coverage, depending on what you actually want answered. Free options like voicemail or Google Voice capture nothing live. Per-minute AI add-ons run roughly $0.10 to $0.50 a minute (confirm current rates with the provider). Human answering services typically start around $200-$300/mo and climb past $500/mo with volume. Flat-rate AI receptionists built for one trade, like Trusso's, run $29/mo for 100 minutes or $49/mo for 200 — no per-minute math required.

That range is wide because "AI answering service" means very different things depending on who's selling it. Some are a generic voice bot bolted onto a voicemail box. Others are tied into your actual business data — your hours, your service area, your price book, your schedule. The price tag usually tracks how much the service actually knows.

Voicemail or Google Voice

Best for: contractors who aren't ready to spend anything on call coverage yet.

This is the default setup for most solo operators, and it costs nothing. The problem isn't the price — it's that voicemail doesn't actually answer anyone. Most callers who hit a generic greeting hang up and call the next name on their list instead of leaving a message. If you want to see what that's actually costing you, this breakdown of the calls contractors miss most often puts numbers on it.

Limitation: zero live coverage. It's a placeholder, not a solution.

Human Live Answering Services

Best for: businesses that want every call handled by a real person, no exceptions.

A live answering service routes your calls to a human agent who can hold a real conversation, calm down an upset customer, and take detailed notes. That flexibility is valuable, but it's priced for it — published pricing for a basic package of minutes often starts around $200-$300/mo, and once you factor in overflow minutes or extended hours, $300-$500+/mo is common. Agents also usually don't know your price book, your crew's schedule, or which jobs are already booked unless you pay extra to integrate your software, which many small shops never get around to doing.

Limitation: cost scales with call volume fast, and most plans still can't tell a caller their own appointment time or invoice balance — that requires integration most human services don't offer.

Generic Per-Minute AI Answering Services

Best for: a business just testing whether an AI voice on the phone is tolerable to callers.

These are usually the cheapest entry point on a per-minute basis, and the appeal is obvious: no human staffing cost, pay only for usage. But per-minute pricing in the $0.10-$0.50/min range adds up quietly — 300 minutes in a month at $0.30/min is $90, often on top of a base platform fee. More importantly, most of these tools are, functionally, a voice bolted onto a voicemail box. They can greet a caller and jot down a message, but they don't know your actual services, your schedule, or your pricing, so they can't tell a returning customer anything useful about their own job. Why generic AI answering services fall short for contractors goes into exactly where this breaks down.

Limitation: no connection to your real business data, so it's a message-taker with a nicer voice, not a receptionist.

Trusso AI Receptionist

Best for: contractors who want an AI that actually knows their business, not just a scripted greeting.

Trusso's AI Receptionist is an add-on to any Trusso plan — $29/mo for 100 call minutes or $49/mo for 200, with $15 recharge packs for 50 extra minutes that roll over month to month instead of expiring. Because it's connected to your Trusso account, it knows your services, hours, service area, and policies, and — once a caller verifies their name and address — it can tell that specific customer their own appointment time, job status, estimate, or invoice balance, and resend documents to contacts already on file. You keep your existing business number through conditional call forwarding (a dedicated number is available on the Unlimited plan), and it always discloses that it's an AI up front.

Limitation: it's an add-on to a Trusso subscription, not a standalone answering service, and it won't quote prices you haven't published, edit a schedule, or touch an invoice or payment — if it's unsure, it falls back to taking a callback message instead of guessing.

What One Missed Job Is Worth

The real math on "is this worth paying for" isn't the monthly fee — it's what a single missed call costs you. A homeowner calling about a $350 drain cleaning who hangs up and books the next plumber on the list already covers a $29/mo plan twelve times over for the year. A missed call about a $4,000 fence job or an $8,000 remodel makes the comparison almost silly. How missed calls cost contractors thousands of dollars and what happens to calls a contractor doesn't answer both walk through the lead-value math in more detail if you want to run your own numbers against your close rate and average ticket.

The honest caveat: an answering service — human or AI — only pays for itself if you're actually missing calls today. If you already answer everything yourself and never let a lead go to voicemail, the cost is pure overhead. For most contractors juggling a jobsite, a truck, and a phone that won't stop buzzing, that's not the reality.

Where Trusso Fits

If you're already comparing software to run estimates, scheduling, and invoicing, the AI Receptionist is built to sit on top of that same system rather than as a separate tool with its own learning curve. Because it reads from the same price book and job calendar you already use in Trusso, it can answer the questions a generic bot can't — what time is my appointment, is the job still on, what do I owe — without ever making up a number you haven't approved. For a deeper look at the mechanics, can an AI receptionist tell customers their job status or invoice balance covers exactly what it will and won't say.

This comparison reflects publicly available and Trusso-published pricing as of early 2026; always confirm current rates directly with any provider before committing, since per-minute and plan pricing shift more often than flat-rate software pricing does.
