Why do tiling quotes that look fine on paper start costing money on site?
A quote built from memory or a scribbled note on the ute dash often looks complete right up until the tiler is standing in the shower recess realising the waterproofing membrane, the levelling clips or the adhesive for a large format tile were never priced in. The job wasn't underquoted on purpose. A step was simply left off because nothing forced it to be checked.
Most tilers quoting across bathrooms, kitchens and splashbacks are holding dozens of small line items in their head at once: screed depth, falls to the drain, membrane coats, trims, grout colour matching, breakage allowance on tile supply. When that system exists only in one person's memory, consistency can drop the moment that person is rushed, tired, or quoting a job type they don't price every week. The quote wasn't wrong when it was written. It was just missing what nobody checked.
Why does a tiler's day rate never seem to match the hours actually worked?
A day rate on paper assumes a full productive day, but travel between jobs, time waiting on another trade to clear a shower recess before the membrane can go on, and the gap between arriving on site and actually laying tile all eat into that rate without ever being written down anywhere. The real number only shows up when hours on site are tracked against hours billed, not estimated afterwards.
For a tiler working to a builder's schedule on a renovation, this matters more than it looks. Screed has to cure, other trades have to finish, waterproofing has to be left to go off before tiling starts, and none of that downtime disappears just because it wasn't costed. This is also where gross profit margin gets blurred: a tiler who prices a bathroom at a day rate but loses hours waiting on someone else is quietly handing margin away, job after job, unless it's checked at the point the quote goes out, not once the books are done.
What should a tiler document before buying any software at all?
Before looking at any app, the job is to write down, step by step, exactly what belongs on a standard bathroom quote, a standard screed job and a standard floor preparation job, because that process is what exposes the steps you've been quietly skipping. Software only earns its keep once it is running a system you have already checked, not replacing a system that never existed.
Picture a tiler whose quoting was slow and manual, built fresh each time from memory, and with so many parts to a bathroom or wet area job it was easy for a small material, a bracket, a post, a trim, to be left off the quote and then be missing on site once the job started. Once a quoting template existed with a checklist built for each job type, covering every material down to the small fixings, that gap closed. Not because the tiler suddenly remembered better, but because the system didn't let the job move forward until the right information was there.
What can AI agents actually take off a tiler's plate?
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, so quoting, job tracking and warranty records happen the same way every time without you holding it all in your head. For a tiler, that can mean an agent running the quote checklist, logging hours on site against hours billed, and flagging when a job's materials or margin don't match what was priced.
This is data first: the numbers your business is already producing, job by job, become the thing the agent checks against, rather than a guess about how the last bathroom went. Instead of chasing a missed item after the job has started, the agent sits before that point and holds the job there until waterproofing, screed, adhesive and breakage allowance are all accounted for.
Does a tiler need to build their own system or just buy an app?
Some off the shelf tools, a scheduling app, a basic invoicing tool, can suit a tiler well enough, and the business's own data will show which ones genuinely earn their place. The real choice worth making is building the quoting, hours and materials tracking around how your jobs actually run, your square metre rates against your day rates, your supplier pricing, rather than renting a tool built for every trade at once and bending bathroom and wet area jobs to fit it.
AI agents built around your own job records can sit underneath whichever apps you keep, picking up the quoting, tracking and warranty follow up regardless of which scheduling tool or invoicing app runs the rest of the business. The software changes. The system behind it, built on your own numbers, is what stays consistent.
How does Data First Coaching approach this?
Data First Coaching starts from a tiler's own job records inside the Trade Business Intelligence, not from a description of how the business runs. It looks at where quotes, hours and materials are actually tracked today, and where they're still held only in memory, because that is usually where the real problem starts, not where it eventually shows up. Greg has seen that without a documented system, “you're probably faced with customers coming to you with disappointment”, often as a waterproofing or warranty claim that comes back long after the job was signed off. The how, building the checklist, the quote template and the hours tracking into a system shaped around a specific tiling business, is worked through inside the Academy, with members who are open minded, innovative and willing to share, because the Trade Business Intelligence is powered by every member.
