AI receptionist for builders: building enquiries get qualified while you pour the slab.
Sayelo, the AI voice agent and AI receptionist for builders, answers 24/7. Extension, wall, patio, renovation: the enquiry is qualified with the area and the ground, the quote visit booked, and small jobs outside your scope turned away. From €39 excl. VAT/month, 14-day free trial, no set-up fees.
A cement mixer turning, a slab to pour before the rain, and a phone ringing in the back of the van. Sayelo answers, asks what the customer wants built (an extension, a boundary wall, a patio, a renovation), notes the approximate area, the ground and the timescale, and books the quote visit in your calendar. Small requests outside your scope get a polite answer. The AI announces itself in its very first sentence.
from €39 excl. VAT/month afterwards · no commitment · the AI announces itself on every call
A building firm works to the rhythm of its sites and the seasons. The phone rings in the van while the slab is being poured, for projects that are rarely precise (an extension, a patio, a wall) and for plenty of calls that aren't jobs at all. In the evening, voicemail holds incomplete requests and customers who have already gone elsewhere.
Sayelo's AI receptionist answers while you're on site. It introduces itself as an AI assistant, qualifies the type of work, the area, the ground, the access and the timescale, books the quote visit in your calendar, texts the link for receiving photos, politely turns away small jobs outside your scope and recognises suppliers, architects and project managers. It gives your start dates exactly as you have provided them and never prices any work without a visit.
Day to day
What builders face on the phone.
A building site doesn't wait for the phone
A slab is poured in one go, a wall goes up with two people, a trench is filled in before the rain. Nobody puts down the trowel to answer, and voicemail, in the noise of the site, doesn't get listened to before the evening.
Enquiries too vague to be priced
“I'd like to extend my house” says nothing about the area, the ground, the access or the timescale. Before going out, you have to call back and ask ten questions, and every call back is an hour taken from the site.
Quote visits to fit in
A quote for structural work means a visit, often on a Saturday morning, with the customer present and the plans to hand. You need a slot, an address, a reminder, and there's nobody to organise them during the week.
Calls that aren't for you
A tile joint, a shelf to put up, a materials sales rep, a platform selling leads. Each one takes time, and none of them builds a wall.

What the agent does
What your AI receptionist does for a building firm.
Qualifies the size and type of the job
Extension, adding a storey, boundary wall, patio, slab, renovation, opening in a load-bearing wall. The agent notes the approximate area, the type of ground, access for machinery, whether there are plans or planning permission, and the desired timescale.
Books quote visits
In the slots you set aside, often Saturday morning or late afternoon, in your calendar, with the address and confirmation that the customer will be there. Confirmation SMS and reminder the day before.
Sends the form and the photo link
During the call, it texts the link you have prepared for receiving photos of the site, the front of the house or the plans. You arrive at the visit knowing what to expect.
Turns away enquiries outside your scope
You define what you don't do: small jobs, tiling only, work below a certain value. The agent says so politely and points the caller to the alternative you have planned, without booking a pointless appointment.
Recognises suppliers, architects and project managers
A builders' merchant, an architect consulting you, a project manager, a customer whose job is under way. The agent recognises them and applies your instructions for each contact: transfer to the site manager or a message.
Takes the season into account
You give your start dates according to the time of year and your order book. The agent passes on these dates as they are, without promising a start date you haven't given.
Emergencies
Emergencies: what gets transferred, and when.
- Wall or structural element at risk of collapse, sudden crack, danger to people: instruction to evacuate and call the emergency services if needed, then immediate transfer
- Job under way with a problem on site, delivery, bad weather, machinery: transfer to the site manager according to your instructions
- New structural project: qualification, then a quote visit in the calendar
- Small jobs outside your scope: polite answer and redirection, no appointment
- Supplier, architect, project manager: instructions specific to each contact
You decide who takes site calls and when: the site manager during the day, the office for quotes, your mobile for structural emergencies. The agent states your visit fee if you charge one, and never gives a price for work over the phone.
Each transfer number can be offered only at certain times, in your country's time zone: an on-call line in the evening and at weekends then takes priority over the usual number. Outside these times, the agent takes a message and sends it to you. The transfer is direct: if nobody answers, the caller reaches the voicemail of the transfer number.
Step by step
A typical call, from the first ring to the summary.
The ring
The agent answers while the cement mixer is turning, and introduces itself as the company's AI assistant.
The project
Extension, wall, patio, renovation, slab. It identifies the type of work and checks that it falls within your scope.
The site
Approximate area, flat or sloping ground, access for machinery, plans or planning permission, timescale. It notes what's needed to prepare the visit.
The visit or the transfer
Structural danger or a job under way: transfer according to your rules. Otherwise, a quote visit in your calendar, confirmed by SMS.
The SMS
The customer receives the confirmation, the photo link and the meeting address, then a reminder the day before.
The summary
After the call, an email with the summary, the project sheet, the photos received and the full transcript.
Calendar and tools
Your appointments in your calendar, your calls in your tools.
Quote visits go into your calendar (Google Calendar, Microsoft 365 or Cal.com), in your visit slots. Project sheets are sent to your quoting software by webhook, and your suppliers, architects and project managers saved in Sellsy or monday.com are recognised as soon as the agent answers.

Frequently asked questions
Questions from builders.
Does it qualify the size of the job?
Yes. It asks for the type of work, the approximate area, the type of ground, access for machinery, whether there are plans or planning permission and the desired timescale, then records everything in a project sheet. You decide on the visit from a complete sheet, without calling back first.
Does it book quote appointments?
Yes, in your calendar, in the slots you set aside for visits, for example Saturday morning. It confirms by SMS with the address and sends a reminder the day before. If the customer needs to move the visit, it does so and frees up the slot.
Does it filter out small requests?
Yes, according to the scope you define. For tiling only, a small repair or work below your threshold, it answers politely, explains that the company doesn't do this kind of job and points the caller to the alternative you have planned, without booking an appointment.
Does it send the photo form?
Yes, during the call and with the customer's consent. It texts the link you have prepared, a form or a messaging app, for receiving photos of the site, the front of the house or the plans. The photos are waiting for you before the visit.
Does it handle calls from suppliers?
Yes. A builders' merchant, a plant hire company or a haulier recognised by their number follows the instruction you attach to them: transfer to the site manager or a message with the delivery reference. Sales reps, on the other hand, never get through to you.
Will my clients know they're talking to an AI?
Yes, it says so as soon as it answers. A customer who wants an extension built mostly wants their project taken seriously and to be offered a visit. They get that, while you finish the slab.
Can I keep my number?
Yes. You keep your current number, as you prefer: by forwarding it to your agent or, in France, by porting it, on all plans. A new number is also included from the start of the trial, if you would rather start from scratch. Either way, the number painted on your site board always gets answered.
