Why does a carpentry quote look fine on paper but come in thin on site?
A carpentry quote often looks fine on paper because the margin is calculated against the lines that were typed in, not the job that actually gets built. When a bundle of brackets, a run of flashing, or an extra day of subcontract labour gets left off, the quoted gross profit stays the same number on the page while the real cost of timber, hardware and day rate labour on site climbs past it. The carpenter only sees the gap once the job is invoiced, and by then the bank balance tells a different story to the quote.
This usually shows up once a carpentry business moves past the owner doing every job themselves. In the growth phase, with an apprentice on the tools and a subbie running a second site, the owner cannot personally check every line of every quote before it goes out. Decks, pergolas and fix-out jobs all carry different material lists, and a quote built from memory of the last similar job is a quote built on an old picture, not this job's actual list of timber, fixings and hardware.
What is actually going wrong when materials get missed off a quote?
What looks like a careless estimator is usually a structural problem: quoting happens in short bursts between jobs, under pressure, with no fixed list of what a deck, a pergola or a fit-out actually needs line by line. The fix is not a telling off, it is a system that does not let the quote move forward until every line is there.
The number that tells the truth here is not the quoted gross profit, it is the gap between quoted gross profit and the actual cost once the job is built, tracked job by job rather than guessed at the end of the year. A carpenter who only checks margin at tax time is checking a number that is already months out of date. Data first thinking means the business looks at that gap on every job as it closes, so the pattern of what keeps getting missed becomes visible instead of being put down to one bad quote.
What can AI agents actually do for a carpentry business?
An AI agent is software that does a piece of office work the way you would do it yourself, using your prices, your wording and your rules, without you typing it every time. For a carpentry business, that means an agent can hold your full pricing against a wholesaler's catalogue, build the quote out against a checklist for the type of job, and flag a line that looks thin or missing before the quote goes anywhere near the customer.
Greg teaches that agentic AI does not stop at answering a question. It can do the work: pulling a full pricing structure from a supplier's catalogue instead of you typing every stud, bracket and fixing in by hand every time you quote a frame or a deck. Members inside the Academy's AI Club pool what they are building and what has gone wrong in testing it, so a carpenter working this out is not starting from nothing. They are using checks that electricians, plumbers and other builders have already tested on their own quotes.
How would this work on a deck or pergola quote?
Picture a carpenter who quotes a run of decks and pergolas most months. Quoting is slow and manual, built fresh each time from a rough tally of boards, posts, brackets and fixings, and with so many small parts on each job it is easy for something to be left off the page and then be missing on site.
What changes this is a quoting template with a checklist built for each type of job, covering every material the job needs down to the brackets and the post caps, with an AI agent holding that checklist against the supplier's current pricing so the quote cannot be finished until every line is there. The carpenter still sets the prices, still makes the call on the job. The agent just stops a thin quote from going out the door looking healthy.
Should a carpenter just buy quoting software instead?
Some off-the-shelf quoting tools suit some carpentry businesses well, and the honest answer is that a carpenter's own job and pricing data will show which ones earn their keep and which ones are being paid for and barely used. A generic tool built for every trade at once treats a deck quote the same as a bathroom fit-out, which is rarely how a carpenter's own pricing actually works.
The other option is owning a system built around how your own jobs run: your supplier list, your day rate, your subcontract arrangements, your own job types from framing through to door hanging and fix-out. That system is shaped to the business rather than rented from someone else's template, and it is built from the business's own data rather than a guess at what carpenters in general need.
How does Data First Coaching approach this?
Data First Coaching, built by Greg Allan, starts with the carpenter's own numbers rather than a conversation about how busy things are. Through the Trade Business Intelligence, it looks first at the gap between quoted gross profit and actual job cost across recent jobs, because that gap usually shows where a quoting process is leaking before anyone can point to a cause. Greg has talked about “how much faster we're gonna be able to implement these things into our business” once the right system is in place. The how, the actual build of the checklist and the agent behind it, is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member and the Academy is built for carpenters who are open minded, innovative and willing to share what they learn.
