What does coaching actually cost a plumbing business?
The real cost of a business coach is rarely just the invoice. It is the hours the owner, or a tradesperson, spends away from callouts, quoting and the van while sitting in sessions, explaining the business and doing homework that has nothing to do with today's jobs. For a small plumbing outfit, every hour off the tools is an hour not billed.
That cost compounds when the coaching is generic. If a program hands the same worksheets to a plumber doing emergency burst pipe callouts, a plumber running strata maintenance contracts, and a plumber doing bathroom renovations, the advice cannot fit any of them well. The hours go in, but the business underneath barely changes because nobody looked at what that particular plumbing business's own numbers were actually saying.
Why do many plumbers feel unsure coaching will pay off?
Most plumbers have been burned, or know someone who has, by coaching that starts with a questionnaire about the business rather than the business's own figures. The owner explains gut feel about last quarter, the coach nods, and the advice that comes back could apply to a sparky or a landscaper just as easily.
What looks like the problem for a plumbing business, thin margins, too many emergency callouts, slow quote turnaround on gas fitting work, is often a symptom. The real cause can sit further back: underpriced hot water replacements, poor tracking of travel time between jobs, or a backflow testing and compliance certificate process that eats office hours nobody is invoicing for. A coach who never looks at the plumber's own job and finance data cannot tell the difference, so the same fix gets tried again next month.
What should a good coach look at first for a plumbing business?
A coach worth paying starts with your own numbers, not a template. The one figure that tells the truth faster than memory is gross profit margin, broken down by job type: what a blocked drain callout actually returns once travel, materials and labour are counted, compared with a bathroom renovation or a maintenance contract with a property manager.
Memory says a job type is profitable because it keeps the diary full. The margin on that job type, pulled from your own data, often tells a different story. A good coach uses that number to find where pricing, quoting or crew time is actually leaking, rather than guessing from a conversation.
What should you ask before you sign up with a business coach?
Before paying for coaching, ask direct questions and watch how they answer. Has this person run a trade business themself, or only coached one from the outside. Will they start by looking at your own job and finance data, or at a generic framework. Do they aim to fix the root cause of a problem with a system, or do they hand out worksheets and call it done.
Ask what happens when a problem will not resolve. A coach whose answer to every issue is “hire someone” or “run more ads” is treating a symptom, not a cause. Greg Allan built Data First Coaching after running his own trade business, and the test he applies is whether the advice could only make sense once it has seen the plumbing business's own numbers.
What are the warning signs of a coach not worth paying?
The clearest warning sign is a salesperson leading the conversation before anyone asks about your numbers. If the pitch is about the program before it is about your plumbing business, that is the order the relationship will keep running in.
Other signs: a coach who has never run a trade business and cannot describe how a quote turns into a job, a program that looks the same for a plumber as it does for a landscaper or a sparky, and advice that treats every slow month the same way regardless of what is actually happening in your margins, your crew's time, or your quote conversion.
How does AI change what a business coach can do for a plumbing business?
AI agents can now take on the non-billable office work that used to eat a plumber's evenings: chasing unpaid invoices, sending compliance certificate reminders, following up quotes that have gone quiet, booking in backflow testing renewals. An agent is software that does a job the way you would do it, with your prices, your wording and your rules, so the work still looks and sounds like your business.
This matters for coaching because a data first approach can place an agent exactly where a problem starts, rather than somewhere general. If late invoicing on maintenance contracts is quietly eating gross profit margin, an agent can sit right there, instead of the owner being told to “get better at admin.” Naming AI agents as part of coaching only makes sense once the coach has seen where your plumbing business actually loses time and margin.
How does Data First Coaching approach this?
Data First Coaching looks at a plumbing business's own numbers first, through the Trade Business Intelligence, before any conversation about what to change. Gross profit margin by job type, quote conversion, travel time and crew utilisation are read alongside ten years of coaching trade businesses, so the starting point is what the business is actually doing, not what the owner remembers about it. That is how Greg Allan finds where a problem really starts rather than where it shows up. The how, the systems and the builds that follow are worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member for every member, and it is built for owners who are open minded, innovative and willing to share what they learn.
