What numbers should a plasterer track every week?

What numbers should a plasterer track every week?

The two numbers that matter each week are job efficiency and operational efficiency. Job efficiency compares the hours a plastering job actually took against the hours it was quoted to take. Operational efficiency compares the hours your whole crew actually billed against the hours they were paid for across the week. Most other numbers an owner watches, revenue, square metres sheeted, quotes sent, tell you how busy the business looks. These two tell you whether that busyness is turning into profit.

Why can a plasterer be fully booked and still end the year with no profit?

A plastering business can have every week filled with sheeting, setting and cornice work and still finish the year with nothing left over. This happens when jobs are being billed but nobody is checking whether each one actually used the hours it was quoted on. The crew can look productive, turning up, working full days, moving between sites, while the margin on every job quietly leaks away because the quoted allowance and the actual hours were never compared.

A plasterer's books can show a healthy run of invoices and still hide this. Revenue tells an owner that work went out the door. It does not tell them what that work actually cost in labour once drying time, rework, callbacks or a trickier ceiling than expected ate into the hours that were priced in.

Why doesn't revenue or jobs completed show the real problem?

Revenue and jobs completed measure volume, not performance against the quote, so a plasterer can be hitting both targets while losing money on individual jobs. A renovation patching job might take twice the hours it was priced for because of extra prep work, while a straightforward ceiling job runs under. Add them together across a busy month and the overruns can quietly cancel out the gains, leaving the owner none the wiser until the accounts are done.

Subcontracting to builders adds another layer. A plasterer paid on a square metre rate for a fit-out might look flat out and still be losing hours to site delays, waiting on other trades, or being asked to patch extra areas that were never priced. None of that shows up in revenue. It only shows up when the hours quoted on that job are checked against the hours it actually took.

What does job efficiency tell you about labour profit?

Job efficiency is the clearest signal you have of whether a plastering job made the labour profit it was priced to make. When a job comes in under the hours it was allowed, the labour profit on it can roughly double. When it runs over, that profit disappears just as fast, sometimes into a loss.

This matters because plastering pricing leans heavily on labour, whether it is a cornice and ceiling job, a full sheet and set, or a patch and match on a renovation. Drying time between coats, access on site, and how many trades are working around your crew all affect how long a job really takes. Checking job efficiency every week, rather than once a job is long finished, means you catch a pattern of overruns while there is still time to do something about the pricing or the way the job is run, not after six months of jobs have gone the same way.

What does operational efficiency show that job efficiency alone misses?

Operational efficiency looks across your whole team's week, not just one job, and it is what exposes a cash problem while there is still time to fix it rather than at the end of the month when the bills are due. A plasterer can have individual jobs running fine and still have a crew whose paid hours are not converting into billable work, because of travel between sites, time spent on quotes, or jobs sitting idle waiting on other trades.

Picture a plastering business where the labour hours being lost are not on the tools at all. A qualified plasterer is spending part of the week in the office pricing technical quotes for larger renovation and new build jobs, hours that are paid but not billable. Once the business starts tracking utilisation for each tradesperson individually, rather than looking at the team as one number, the gap becomes obvious. A low number for one person leads to a direct conversation about what is taking their time, and where it makes sense, that person goes back onto the road rather than staying at a desk.

How can AI agents help a plasterer keep these numbers current?

An AI agent is software that does a job the way you would do it yourself, using your prices, your wording and your rules, and it can be the thing that keeps job efficiency and operational efficiency current without adding another task to your week. Instead of an owner trying to pull hours against quotes from memory or chase timesheets on a Friday night, an agent can sit across your job and finance data and keep those two numbers ready whenever you need them.

This is what data first looks like in practice. The numbers come from the business as it actually ran that week, not from what the owner remembers or assumes. AI agents can also take on the non-billable admin around quoting and invoicing, the parts that eat into a plasterer's own billable hours, so the owner and the crew spend more of the week on customers and jobs rather than paperwork.

How does Data First Coaching approach this?

Data First Coaching, built by Greg Allan, starts with the owner's own numbers through the Trade Business Intelligence rather than a description of the business. For a plasterer, that means looking at job efficiency and operational efficiency first, because Greg has seen how often the real problem sits there rather than in revenue or how busy the diary looks. Greg puts it plainly: “drilling down into job productivity and operational efficiency is probably one of the most important things”. The how, working out where a plasterer's own numbers point and what to do about it, is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member and built for owners who are open minded, innovative and willing to share what they learn.
