Why Most Trades Don't Track Their Time (And Why You Should)
Why Most Trades Don't Track Their Time (And Why You Should)
I've asked dozens of trades the same question:
"How do you track your time on jobs?"
The answers are always some version of:
- "I just know roughly"
- "I work it out at the end of the day"
- "I check my messages to see when I arrived"
- "I don't really"
And look — I get it. When you're elbow-deep in a wall cavity or crawling under a kitchen sink, the last thing on your mind is logging hours.
But here's the problem: if you're not tracking your time, you're almost certainly losing money. Not in an obvious, dramatic way. In a slow, quiet, "where did all my profit go?" way.
The maths that nobody wants to hear
Let's say you're a plumber and you charge £60/hour.
On a typical day, you do three jobs. And on each one, you underestimate your time by just 30 minutes.
That's 1.5 hours a day you're not billing for.
1.5 hours × £60 = £90 a day.
Five days a week, that's £450.
Over a month? £1,800.
Over a year? £21,600.
Twenty-one grand. Gone. Not because you didn't do the work — but because you didn't write down how long it took.
Obviously not every trade underestimates by that much every day. But even half that number is over ten thousand quid a year. That's a holiday. That's a new van. That's breathing room.
Where the time actually goes
The problem is that trades think of "the job" as just the hands-on bit. The actual fixing, fitting, wiring, plumbing.
But the job includes:
- Driving there — that's your time
- Loading the van — that's your time
- Talking to the customer — that's your time
- Diagnosing the issue — that's your time
- Going to get parts — that's your time
- Setting up and packing down — that's your time
- Cleaning up — that's your time
- Sending the invoice — that's your time
A "1-hour job" is almost never 1 hour. It's usually 1 hour 45 by the time you account for everything around it.
If you only bill for the hands-on bit, you're working for free the rest of the time.
Why trades resist tracking time
I've heard all the reasons. And most of them are fair enough:
"It feels like clocking in." I know. Nobody became a sparky to fill in timesheets. But you don't need a timesheet. You just need to note when you arrived and when you left. That's it.
"I'll remember." You won't. Not accurately. Especially not after three jobs and 47 WhatsApp messages. Memory is unreliable — even when you think it isn't.
"It slows me down." It takes about 10 seconds. If 10 seconds is slowing you down, something else is wrong.
"I charge fixed prices anyway." Fine — but how did you work out the fixed price? If it wasn't based on real data about how long jobs take, you're guessing. And guesses cost money.
What changes when you start tracking
Once trades actually start logging their time, the same things happen every time:
1. They realise they're undercharging. Almost without exception. The first week is always a shock. "That job took me HOW long?"
2. Their quotes get more accurate. Because they're basing prices on real hours, not gut feelings. Fewer surprises, fewer losses.
3. They spot time sinks. Jobs that seem profitable but actually eat up way more time than expected. Customers who always add "one more thing." Travel that doesn't justify the job.
4. Their invoices get cleaner. No more guessing at the end of the day. The time's already recorded, so the invoice writes itself.
5. They earn more without working more. Because they're finally billing for ALL the time they spend, not just the bits they remember.
The simplest way to track time as a trade
You don't need a complicated app. You don't need to log every minute of every day.
Here's the bare minimum that works:
When you arrive at a job → note the time. When you leave → note the time.
That's it. Two data points per job. Takes 5 seconds each.
If you want to go further:
- Note any extra trips (parts run, second visit)
- Note any breaks
- Note any additional work the customer asked for
But honestly, just start with arrival and departure. That alone will change how you price.
"But I charge day rates"
Day rates are fine. But do you know how many hours your "day" actually is?
Some trades charge a day rate and work 6 hours. Others charge the same day rate and work 10.
If you don't track the hours, you've got no idea whether your day rate is actually covering your time — or whether you'd be better off charging hourly.
Data gives you options. Guessing gives you nothing.
How Clearwork makes time tracking painless
In Clearwork, logging time takes two taps:
- Open the job
- Add labour entry (start time, end time)
Done. It's saved against the job, linked to the customer, and ready for the invoice.
No paperwork. No spreadsheet. No "I'll add it later."
When you invoice the job, the hours are already there. You just hit send.
Over time, Clearwork builds a picture of how long your jobs actually take — which means better quotes, better pricing, and no more underbilling.
Start this week
You don't need to overhaul your business. You don't need new tools or systems.
Just pick one day this week and track your time on every job. Arrival time. Departure time. That's all.
At the end of the day, look at what you logged versus what you billed.
If those numbers match, you're doing fine.
If they don't — and for most trades, they won't — you've just found where your money's been going.
