This is the question we hear most from builders and trade business owners, usually followed by “and can I trust it”.
What AI can do today
Draft quantities from drawings. On consistent drawing sets, AI can produce a first pass takeoff against the elements your estimators already use. It works best on repetitive project types such as fitouts, residential and light industrial. It is a draft and it is faster than starting from zero.
Price from your own history. Most builders and trades have years of priced jobs in their estimating and accounting software that nobody queries. AI can pull the rate you charged and won with for similar work, per customer type, and show you which past job it came from.
Pull current supplier and subcontractor pricing. From supplier lists, recent invoices and quotes received. The draft does not use last year’s numbers.
Put it in the right template. Builders who tender to several head contractors or clients spend a surprising amount of time reformatting the same scope. That part is entirely automatable.
Draft trade quotes from site notes. For a plumber, electrician or HVAC contractor, a quote can be drafted from the site visit notes and photos. It lands in your template with your pricing, ready for the owner to check.
What it cannot do
Own the number. Pricing risk, reading the client and knowing which subcontractor will turn up. That is the estimator’s job.
Work from chaos. Inconsistent drawings, scopes that change daily, pricing that lives in one person’s head with no history behind it. AI needs consistency to be reliable.
Guarantee accuracy without testing. Run any setup over your past jobs before it goes live. Then you know how often it is wrong and by how much, and you can set the review threshold.
Product or custom build
If you are a small builder or a trade business doing common work, buy a product first. Buildxact, simPRO, ServiceM8, Tradify and others have quoting built in and are improving it with AI. A product is cheaper and faster than anything custom.
Custom work earns its cost in three situations. Your pricing logic is specific to your business and a product cannot express it. You tender in several client formats and the reformatting alone costs days. Or the quote needs data from systems the product cannot see, such as your accounting history or a supplier portal.
What it changes for the estimator
It changes their day rather than their job. A senior estimator who spends four days measuring and one day pricing risk changes shape. They spend half a day reviewing a draft and the rest on risk and the next tender. Businesses that set this up typically price more tenders with the same team. They do not cut people.
