AI Assistant for Contractors: A Buyer's Guide

What people mean by an AI assistant for contractors

Strip away the marketing and it is software that answers your incoming leads the way a good office manager would, at any hour, without being paid for the hours it spends waiting. It picks up the phone. It replies to the text. It answers the form on your website. It asks what is going on, and it does something with the answer.

You will see the same thing sold as an AI receptionist, a virtual receptionist, an AI phone answering service, or a conversational agent. The words are close to interchangeable and nothing important turns on which one a vendor picked. What does turn on something is where the software stops.

It matters more here than in most categories because of how the calls arrive. In a January 2025 CallRail analysis of 1.1 million calls to local businesses, 14% of calls to home-services companies went unanswered. Every one of those was someone who, a moment earlier, wanted to pay somebody to do the work.

The three places these products stop

It answers. The assistant picks up, sounds human, takes down a name and a number, and sends you a summary. This is the bulk of the category and it is genuinely better than voicemail. But it hands you back a callback list, and the callback list was the problem.

It answers and books. The assistant qualifies the job, checks your calendar, and puts the visit on it while the homeowner is still on the phone. This is the meaningful step up, because the work leaves your evening entirely. A good number of vendors do this well.

It answers, books, collects, and gets you reviewed. The assistant stays with the job through the quote and the payment — and the moment it’s paid, asks the customer for the Google review, so the finished job helps win the next one. Fewer products carry a job that far, because it means handling the money as well as the conversation.

Being straight about what is not a differentiator

Answering the phone well is close to table stakes now. If you have already heard another vendor’s demo, ours will sound like the same category, and that is an honest description rather than modesty. Multi-channel is not rare. Review requests are not rare. Taking a card payment is not rare.

The part that is genuinely uncommon is the pricing: a share only on the jobs it wins you, over a small minimum, instead of the same flat fee whether it booked you twenty jobs or none. And a deliberately narrow scope: four things done well — answer, book, collect, get reviewed — with nothing to implement. That is the argument we would make for ourselves, and the one we would defend.

Seven questions to ask before you sign

Take these to any vendor, us included. Six of the seven are questions a good competitor will pass, and they are marked, since a checklist that only one product can pass is not a checklist.

Does it answer every channel, or only the phone?
Homeowners text and fill in web forms at least as often as they call, and the ones who text are usually the ones who called someone else first. An assistant that only covers the phone leaves the other doors unattended.
Several other vendors answer this one well too.
Does it answer at 2 a.m., or hand off to voicemail?
The call that matters most — no heat, water coming in, a branch through the roof — rarely arrives at 10 a.m. on a Tuesday. Ask specifically what happens outside business hours, because "24/7" sometimes means "24/7 voicemail".
Several other vendors answer this one well too.
Can it actually book, or only take a message?
This is the single biggest dividing line in the category. Taking a message moves the work to your evening; putting the visit on the calendar removes it. Ask to watch it book during the demo.
Several other vendors answer this one well too.
Does it know your business, or is it generic?
An assistant trained for local businesses in general will book a haircut competently and have no idea that a gas smell means leave the house, or that a bowing basement wall is not a next-week problem. Ask how it learns your services, your service area, and your prices.
Several other vendors answer this one well too.
What happens when it doesn't know the answer?
The failure mode you care about isn't a wrong word, it's an invented fact — a price you never approved, a service you don't offer. Ask what it does at the edge of what it knows, then ask it something obscure while you're watching.
Several other vendors answer this one well too.
Does it ask for the Google review at the right moment, on every job?
Most can send a review request — ask when it goes out and who has to remember. Right after the job is paid, when the customer is happiest, and on every job without anyone remembering, is what turns finished work into the reviews the next homeowner reads first.
Several other vendors answer this one well too.
What does it cost in a month when it produces nothing?
Most of this category is flat monthly software: the bill is identical whether it booked you twenty jobs or none. That's not dishonest, but it does mean the vendor carries no risk. Ask what they charge in a bad month, and what that tells you about their confidence.

Where Plinth sits

Plinth answers every call, text, and web form in seconds, at any hour, from the facts you give it about your business. It books the visit on your calendar. It sends the quote, collects the deposit and the balance, and asks for the review once the job is paid — so every finished job helps win the next one.

You keep your number, your website, and whatever software already runs your jobs. If all you want is the phone answered, a cheaper flat-rate product will do that, and we would rather tell you so than sell you something you do not need.

Common questions

What is an AI assistant for contractors?

Software that answers your incoming leads like a person would, then does something useful with them. At minimum it picks up calls, texts, and web forms around the clock and replies in seconds. The better ones also ask the questions you would ask, book the visit on your calendar, and hand the conversation to you when it should. The weaker ones take a message, which leaves you with the same callback list you already had.

Is an AI assistant the same as an AI receptionist?

Yes — the two phrases describe the same product, and vendors use them interchangeably. "Receptionist" tends to describe the phone-answering job specifically, and "assistant" is the broader word. Nothing turns on which one a vendor prints on their website. What turns on something is where the software stops: at the answered call, at the booked appointment, or at the paid invoice.

Will it sound like a robot to my customers?

Try it and judge for yourself rather than taking anyone's word for it — including ours. You can have Plinth's assistant call you in about a minute, answering as your own business, and hear exactly what a homeowner would hear. This is also the right test to run on every vendor you're considering: a demo you drive is worth more than any recording on a marketing page.

Will it make up an answer if it doesn't know something?

It shouldn't, and this is worth testing deliberately on any vendor. Plinth answers from the facts you give it in setup — your services, service area, hours, and the questions you get asked most — and books the visit for anything outside them rather than guessing. Ask any vendor what happens at the edge of what their assistant knows, then ask something obscure during the demo and watch.

Do I have to change my phone number or my software?

No. Keep the number, keep the field-service software, keep the website. Plinth is the layer above the tools that run the work — ServiceTitan, Housecall Pro, Jobber and the rest run the job once it's sold, and they run it well. Anything that asks you to rip out what already works is asking for a decision you're right to put off.

What does it cost?

$50/month as a minimum, or a small share of the jobs Plinth causes if that’s more — never both. The share is charged only once the job is paid. The share is the part worth understanding: if it books you nothing, there's nothing for us to take a share of. See how the model works at joinplinth.com/pricing.
