Artificial intelligence (AI) can help with seven weekly jobs in a small construction firm. It can take a first pass at calls, quotes, scheduling, site diaries, safety paperwork, marketing and invoices. It cannot sign off any of them. The table shows one tool for each job, with its published starting price.
Prices come from each company's own pricing page, read on 23 October 2026. We have not tested these tools. We compare what they publish. Where a page prints only "$", we copy it and add no country.
Where to start: answering calls, drafting quotes and writing up site notes. They repeat every week, and a person can check each result in minutes. That is our reasoning from the table, not a measured saving.
The seven jobs, one tool each
| Job | What AI can do today | Example tool and published starting price | What still needs a person |
|---|---|---|---|
| Answering calls | Picks up, takes the caller's details, sends you a summary | Goodcall Starter: "$79 a month", 100 unique customers a month, then 79¢ each. The page prints only "$". Tax is not stated. Goodcall pricing | Calling back, site visits, and checking what the system tells callers |
| Quotes, estimates and takeoffs | Drafts a scope and line items; some tools read drawings | Buildxact: Go plan "$0", with "5 complimentary credits". The lowest paid plan, Foundation, shows "$199/mo" beside "$169/mo" and "Billed annually at $2,030". The page does not say in these words which figure is the monthly price. Base plans and add-ons are "subject to GST, where applicable". Buildxact pricing | Quantities, rates, wastage and what is left out |
| Scheduling and quoting in one app | Books jobs, sends quotes, drafts quotes with a button | Jobber Core, one user, billed annually: "$29/mo". New customers get "$21/mo" for the first 12 months; the page says "Offer ends October 30th". Prices are in US dollars and exclude sales tax. Jobber pricing | Who goes where, and the real time a job takes |
| Site diaries and daily reports | Not confirmed. The pricing page we read names no AI feature and no daily report | Fieldwire Basic: free ("0" per user a month) for 5 users, 3 projects and 100 sheets. Pro: "$39" per user a month, billed annually. Reports and exports start on Pro. Tax is not stated. Fieldwire pricing | What happened on site, written in your words |
| Safety paperwork | Writes a first draft of a checklist or toolbox talk | No tool priced. SafetyCulture's pricing address sent us to a different website, so we have not listed it. | Every item, checked by someone who knows the site and the rules |
| Marketing | Drafts posts and captions from your job photos | Canva Free: "US$0", up to 20 Standard or Premium AI uses. Pro: "US$144" a year for one person. Prices exclude tax. Canva pricing | Which jobs and photos you may show, and the customer's permission |
| Invoices and admin | Fills a document from the details you type | Papertern's free invoice and quote makers. Papertern is made by the same company as this guide. Papertern | The amounts, and the tax your country asks for |
What we could not confirm: no safety tool is priced, because SafetyCulture's pricing address sent us to a different website. Raken, a daily-report app, shows no price and points to a demo request. ChatGPT's pricing page shows plan names with no amounts. No page we read names an AI feature for site diaries. Jobber's page does not say which plan includes quote drafting.
Answering calls while you are on the job
An AI answering service takes calls when your hands are full. It writes down who rang and why. Goodcall bills by the number of different customers who ring in a month, not by the minute. Its page says: "We never meter minutes."
For plans from many companies, with the extra charges, see the AI answering service price comparison. To work out a cost for your own call volume, use the AI receptionist cost guide. For the human option, read answering services for contractors.
Quotes, estimates and takeoffs
A takeoff counts what a job needs from the drawings: floor area, wall area, fittings. Buildxact lists "Digital Takeoffs" on its first paid plan and "AI Estimating" on the free Go plan, as its page words it. A general AI assistant can also draft a scope from a plain description. The worked example below shows how far that gets you.
For a finished quote, a free contractor estimate template opens the quote maker for your country.
Worked example: one bathroom job, drafted by AI
This is an invented job with invented amounts. An AI model (the same kind of assistant this page describes) drafted these lines, and the rates are placeholders. We did not trial anything. The point is to show what a first draft gets wrong.
The request the AI was given: "Draft a scope and line items for a small bathroom renovation. The room is 2.4 m by 1.8 m. Replace the bath with a walk-in shower. New vanity and toilet. Retile the floor and the shower walls. The shower walls total 8 square metres. Show quantity, unit, rate and amount."
What the AI drafted (rates are the AI's own placeholders):
| Description | Qty | Unit | Unit price | Amount |
|---|---|---|---|---|
| Demolition and waste removal | 1 | job | 900.00 | 900.00 |
| Plumbing: shower, vanity and toilet connections | 8 | hour | 110.00 | 880.00 |
| Waterproofing membrane, floor and shower walls | 12.32 | m² | 45.00 | 554.40 |
| Tiles, supply | 12.32 | m² | 60.00 | 739.20 |
| Tiling labour | 12.32 | m² | 90.00 | 1,108.80 |
| Vanity, supply and fit | 1 | each | 750.00 | 750.00 |
| Toilet, supply and fit | 1 | each | 400.00 | 400.00 |
| Total | 5,332.40 |
The floor is 2.4 m × 1.8 m = 4.32 m². Add the 8 m² of shower walls and the tiled area is 12.32 m². The AI's sums were right.
What we corrected:
- Tile quantity. The draft bought exactly 12.32 m² of tile. Tiles are cut and broken, so the example adds 10% (12.32 × 1.1 = 13.552, rounded up to 13.6 m²). The 10% is an assumption for this example, not a rule.
- Rates. The AI made up its unit prices. We replaced them with the example firm's own rates. An AI assistant cannot know what your hour costs.
- Hidden damage. The draft had no line for what is found when the old bath comes out. The example adds an allowance (a provisional sum) of 500.00.
- Tax. The draft said nothing about tax. All amounts here exclude tax. Add it the way your country's tax office says. All measurements in the example are metric: metres and square metres.
The finished estimate (example rates):
| Description | Qty | Unit price | Amount |
|---|---|---|---|
| Demolition and waste removal | 1 | 950.00 | 950.00 |
| Plumbing (hours) | 8 | 105.00 | 840.00 |
| Waterproofing membrane (m²) | 12.32 | 48.00 | 591.36 |
| Tiles, supply (m²) | 13.6 | 62.00 | 843.20 |
| Tiling labour (m²) | 12.32 | 95.00 | 1,170.40 |
| Vanity, supply and fit | 1 | 780.00 | 780.00 |
| Toilet, supply and fit | 1 | 420.00 | 420.00 |
| Allowance, hidden damage | 1 | 500.00 | 500.00 |
| Total, before tax | 6,094.96 |
The corrected total is 762.56 higher than the AI's draft (6,094.96 − 5,332.40). The AI saved the typing. It did not know the rates, the wastage or the risk. You can type the finished lines into the Description, Qty and Unit price columns of the Papertern quote maker for your country.
Scheduling, site diaries and daily reports
Job apps now offer AI help with the paperwork. Jobber's page names "Auto-drafted quotes" with a "Draft for me" button, and an AI Receptionist sold as an add-on at "$29 /mo". Its page does not say which plan includes the quote drafting.
For site records, Fieldwire's page lists photos, tasks and checklists on its free Basic plan. It does not mention daily reports or a site diary. "Field Intelligence" appears only as a menu link, with no description. Check the company's page for what your plan covers.
Safety paperwork
An AI assistant can give you a first draft of a checklist or a toolbox talk. Treat it as a draft. A competent person who knows your site must check each item. We do not state any country's safety duties on this page. Your regulator's own website is the place for those.
Marketing and admin
Canva's free plan lists AI tools with a cap of "Up to 20 Standard or Premium AI uses". That is enough to try captions and layouts for job photos. Ask the customer before you post photos of their home.
A general AI assistant can draft emails, replies to reviews and follow-ups. Claude's page lists Pro at "$17" a month on an annual plan, or "$20 if billed monthly". It says prices exclude tax. We could not read amounts on ChatGPT's pricing page, so we have not listed it.
For invoices, use an invoice maker for your country.
What AI still gets wrong on a building job
The bathroom example shows the pattern. The sums were right, but the inputs were guesses: rates, wastage and risk. An AI draft also has no idea about your supplier prices, your local conditions or what the old wall hides.
- Check quantities against the drawings or a site measure.
- Replace every rate with your own.
- Read every line before the customer does.
Questions
Which AI is best for a small construction business?
We do not rank tools. Each job has different tools, and the table shows one published price for each. Pick the job that costs you the most time and compare plans on the company's own page.
Can AI read construction drawings and do takeoffs?
Some tools can. Buildxact lists "Digital Takeoffs" on its first paid plan. A person should still check the quantities against the drawings.
Can AI estimate a construction job?
It can draft one. In our example it got the floor area right and made up every rate. Treat the draft as a starting point.
