AI receptionist for builders

The receptionist that runs the enquiry line while you run the site

A builder's phone carries three businesses at once: new enquiries, live projects, and the supply chain. An AI receptionist on your Line number takes the extension and loft enquiries properly, books the site visit into the estimator's diary, sends the merchant and the subbie to the person who owns the job, and keeps chasing the quote over the weeks a client takes to decide. Start with Molly, the pre-built receptionist, or build your own agent for the way you work.

  3. We're thinking about a single-storey rear extension. Kitchen-diner, roughly five metres out. Do you do that sort of thing?

    Molly, AI receptionist
  5. No drawings yet. We're in OX2 7HL. Hoping to start in spring.

  6. Thanks. The first step is a site visit with Mark, our estimator. He can do Thursday at 17:30 or Saturday at 10:00. There's no charge for the visit. Which suits?

Everything a building firm's receptionist does, done by the agent

The best receptionist in a building firm knows a client from a subbie in one sentence. Each row below is a task the agent does on the call, or straight after it.

What a receptionist doesHow the agent does it
Answers in your company name, office or sitePicks up on the first ring with your greeting, 24/7, out of hours only, or only when nobody in the office answers.
Qualifies extension and loft enquiriesAsks the project type, the postcode, whether there are drawings or planning, the budget band, and when they want to start. Follows your question list.
Books the site visitFinds the next gap in the estimator's Google Calendar or Microsoft 365, offers two slots, and books it. Adds a one-tap approval if you want to check first.
Sends suppliers and subbies to the right personRecognises known numbers and routes the merchant to site and the subcontractor to the project lead. Keeps both off the enquiry line.
Answers project questions from the recordTells a known client when the scaffold comes down or when the electrician is due, from the notes you keep in the CRM.
Texts the confirmation and the prep listSends the visit time, who is coming, and what to have ready: drawings, photos, the survey, by SMS or WhatsApp.
Creates the lead and the project in the CRMAdds the client, the address, the scope, the drawings they send, and the visit, to Line's CRM or your project software.
Chases the quote over the weeksFollows up at the intervals you set. Answers questions from the quote. Records a yes, a no, or a reason to wait.
Collects the depositSends the deposit invoice and the terms by email once a client accepts, and confirms when it's paid.

Workflows a building firm builds in an afternoon

Each one is a trigger, a few conditions, and actions in the workflow builder. No code. Change a step and it's live.

New enquiry to site visit
Trigger: Inbound call, graded as a new enquiry
  1. 1The agent asks your qualifying questions: project, postcode, drawings, budget band, start date
  2. 2Checks the postcode is inside your working area
  3. 3Offers the next two site-visit slots from the estimator's diary
  4. 4Books the slot, texts the confirmation, and asks for photos or drawings by WhatsApp
  5. 5Creates the lead in the CRM with every answer attached

Every serious enquiry ends as a site visit in the diary, with the brief already written.

Supplier and subcontractor routing
Trigger: Inbound call from a known contact
  1. 1Look up the caller in the CRM
  2. 2If it's a merchant, ring the site phone for that project
  3. 3If it's a subcontractor, ring the project lead
  4. 4If nobody picks up, the agent takes the message and posts it to the project thread

The enquiry line stays open for clients. Site calls reach site.

Long quote follow-up
Trigger: A quote is sent and no decision recorded
  1. 1After 7 days, the agent texts to ask if they have questions
  2. 2After 14 days, calls, answers questions from the quote, and offers a second visit if the scope has changed
  3. 3After 30 days, emails a note that the price holds until the date you set
  4. 4Records the decision or the reason in the CRM, and stops when you tell it to

A quote stays alive for as long as the client takes to decide, without you remembering to call.

Built in the workflow builder: a trigger, conditions, and actions. The agent is one of the actions.

Tools and integrations the agent works with

A receptionist is only useful if they can get into the diary and the CRM. Connect the tools and the agent uses them on the call.

Google Calendar and Microsoft 365
The estimator's diary for site visits, the project leads' diaries for client meetings. The agent books into the right one.
Your CRM
Creates the lead, then the project. Stores drawings, the scope, the quote, and the decision, so every call has the history.
SMS and WhatsApp
Confirmations, photo and drawing requests, delivery windows to clients, and the deposit reminder.
Email
Sends the quote, the terms, and the deposit invoice. Reads replies so the agent knows a quote was accepted or questioned.
Workflow builder
Enquiry qualification, supplier routing, long quote chasing, and out-of-hours rules, built visually.
Zapier, Make, n8n and the API
Pushes leads and projects into Buildertrend, Tradify, Jobber, or your estimating software through Zapier, Make, n8n, or the API.
Custom tools
Give the agent your own tool: check a delivery ETA with the merchant, read the project programme, or look up a subbie's day rate.

A Tuesday with the agent on the phones

What actually happens when the phone is covered all day.

  1. A merchant calls about a delivery. The agent recognises the number, routes it to the site phone at Elm Road, and logs it to the project.

  2. A homeowner calls about a loft conversion. The agent asks about the roof type, head height, and drawings, and books Mark for Thursday evening.

  3. A plasterer rings to confirm Friday. The agent routes him to Tom, the project lead, with the thread attached.

  4. The quote-chase workflow calls a client from three weeks ago. They accept. The deposit invoice goes out by email within the minute.

  5. A client on a live job asks when the windows arrive. The agent reads the date from the project record and texts it back.

  6. Out-of-hours rule switches on. Calls now go to the agent first. A planning question waits in the inbox for the morning.

Where it hands over to a person
The agent does the receptionist's job, not the building contractors's.
  • A structural or safety question on a live site: a crack, a leak into a neighbour's property, a scaffold concern. The agent flags the project lead at once with the details.
  • A price, a start date, or a scope change. The agent does not commit you. It says the estimator will confirm and books the call.
  • A complaint, a dispute over a stage payment, or a neighbour raising a party-wall issue. The agent takes the details and passes them to you. It never makes a promise you have not authorised.
Molly, or an agent you build
Molly is the pre-built receptionist. Switch her on and she does everything on this page. Or build your own agent in the editor: name it, choose its voice, give it your knowledge, connect its tools, and set what it may do on its own and what it must ask you first. The same agent can take sales calls, customer service, and bookings.
