Why does a glazier's quote look profitable but the bank account doesn't agree?
Most glaziers quote a job as one number: supply and install the glass, the frame, maybe a balustrade, done. Each part of that job can carry a healthy margin on its own, the glass marked up as usual, install labour charged at the normal rate, but once everything is blended into a single price the real return on the job can be thinner than any one line suggests. The business looks busy and the diary is full, while the bank account tells a different story.
A shopfront replacement is a good example. The glass line might carry a strong margin, but the toughened safety glass upgrade, the extra install labour on a tricky frame, or a breakage during the install can quietly eat into what the job actually returns. A balustrade or double glazing component subcontracted out adds another layer that is easy to under price if it is bundled into the one total rather than priced on its own.
Why does the same quoting confusion happen on every measure visit?
Without a documented, repeatable way of pricing, the same confusion resets on every measure visit, whether the job is a shower screen, a splashback, a mirror or a commercial shopfront. Each quote gets built fresh from memory or a rough feel for what the last similar job cost, rather than from a system that already knows the current cost of the glass, the frame and the install labour.
Emergency boarding and insurance work make this worse. A call-out after a break in or a storm is urgent, the quote has to go out fast, and there is little time to check whether the glass supplier's price has moved or whether the lead time on a reglaze has blown out. The same gap between what the quote implies and what the job returns repeats every time, because nothing in the business stops it from repeating.
What is the one number you need to check on every quote?
The number that tells the truth is gross profit margin, checked line by line on every quote you write, glass, toughened upgrade, frame, install labour and any subcontracted balustrade or double glazing component, rather than a single margin guessed across the whole job. Priced like a shopping list, each item shows its own cost and its own margin, so a strong glass line cannot hide a weak install labour line or a rushed emergency boarding call-out on the same job.
This is not a number to check once a month when the books get done. You need to check it at the moment of quoting, before the job is booked in, because that is the only point where you can still change the price. Your pricing also has to move with the glass supplier's current costs and lead times, because a rate you set months ago on reglazing or double glazing work is already out of date by the time your next measure visit happens.
How do AI agents change the office work in a glazing business?
An AI agent is software that does a job the way you would, with your prices, your wording and your rules, built from your own job and pricing data. For a glazier, that can mean turning a measure visit into a quote already priced per item, checked against current glass supplier costs, with a flag raised before the job goes ahead if any line's margin has fallen below what you would accept.
AI agents do not decide what you charge. What they change is the non-billable office work around the quote, chasing a glass supplier for a current lead time, checking a price against the last job of that type, formatting the quote the way your customers expect to see it. That frees you and your crew to spend more time on the measure visit itself and on the customer, which is where a glazier's business is actually won or lost. Working from your own data first, rather than from memory, means the price going out the door reflects what is happening in your business this week, not what it looked like when the rate was last set.
Should you rent off the shelf quoting software, or build systems around your own jobs?
Off the shelf quoting and job management tools can suit you if your work is fairly simple and repeatable, glass and install with little variation from job to job. Your own data shows pretty quickly whether that is your reality or not.
Where your jobs vary, a shopfront one month, a shower screen and a splashback the next, an insurance job or a double glazing installation with a longer lead time after that, generic software built for every trade at once can force all of that into the same template, flattening the detail you actually need to see. The alternative is building systems around how your own jobs run and how your customers buy, so the quote, the pricing and the follow up reflect your business rather than a generic one. Some off the shelf tools earn their place and some do not, and your own data is what shows which is which.
How does Data First Coaching approach this?
Data First Coaching starts from the glazier's own job and pricing data through the Trade Business Intelligence, not from a description of the business. It looks at where the margin actually sits on recent quotes, glass against frame against install labour against any subcontracted balustrade or double glazing work, to find where the gap between the quote and the return really starts. Greg Allan puts it simply: “We price per item, it makes it nice and clear so you understand the costs associated with the job.” The how, building that pricing system and the agents around it, is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member, for owners who are open minded, innovative and willing to share what they learn.
