Calso for builders
Answers the phone on site, so the next big job doesn't go to voicemail.
Calso is an AI phone answerer for Australian builders. When you're on site and can't hear the phone, the call goes to Calso instead of voicemail. It answers questions about the work you do and the areas you cover from your own website and setup interview, takes the enquiry details, and texts them to you straight away. You keep your own number.

The calls builders miss
- You're on site with a nail gun and a radio going. You won't hear the phone, let alone answer it.
- A renovation or extension enquiry can be months of work, and it starts with one phone call.
- Plenty of people ring about a renovation in the evening or on a weekend, when they're home looking at it.
A missed call to your business
Calso answeredThe text you get
New enquiry: Claire, 0491 571 491, Ringwood. Second-storey extension, plans already drawn. Best time to call: after 5pm.

What Calso does on those calls
- Takes the enquiry: name, number, suburb, the kind of job, rough timing, and whether they have plans drawn up.
- Answers questions about the work you do and don't take on, the areas you cover and your licence, from your website and setup interview.
- Texts you each enquiry straight away, with the best time to call back.
- Says it's an AI assistant if anyone asks. It never pretends to be a person.
What it won't do
- It doesn't give prices or estimates. Building work needs a site visit and a proper quote.
- It doesn't connect to job software or book site visits into your calendar.
- It doesn't record calls, and it never guesses: what it doesn't know becomes a message for you.
How your business gets set up
- 01
Calso reads what you've published
Sign up with your business name. Calso reads your website and Google listing for your hours, services, prices and policies.
- 02
A short setup interview
Typed, or by voice if you'd rather. It covers what your website doesn't say, and how you want messages and requests taken.
- 03
Forward the calls you miss
You get your Calso number and choose a plan. Then set your phone to forward the calls you don't answer. Customers keep ringing your usual number.
Setup usually takes under 15 minutes, because Calso reads your website and Google listing first. Nothing is charged until you choose a plan. To undo it, turn call forwarding off.

59%
of 115 Google visits to builders' pages came while the business was closed
Most builders in the directory are closed on weekends, and more than half the Google visits to their pages came while they were closed.
The visit figure counts Google visits to business pages in the Calso Directory from Saturday 24 to Monday 26 October 2026, set against each business's listed hours in its own state's time. It was a weekend-heavy sample, so read it as a sign of when people look businesses up, not a rule for every week. Each of those visits was someone who might have called.
Where they're listed most: Sydney (2,060), Melbourne (1,961), Brisbane (724), Perth (602), Adelaide (409), Gold Coast (292). Listings and hours as published in the directory, October 2026.
Your directory listing needs no account. Calso, the phone answerer, is a separate paid service.

If you tell it in the setup interview what you do and don't take on, it can tell callers that. Anything it isn't sure about becomes a message for you.
