Margin rarely disappears in one dramatic moment. It leaks — a few hours over here, an underquoted job there, a bit of rework nobody logged. Each leak is small enough to ignore. Together they're the difference between a good year and a flat one.
Here are seven signs your workshop is losing margin you can't see — and what to do about each.
1. You can't say which jobs made money last month
If someone asked you to rank last month's jobs by margin, could you? If the honest answer is 'not without a lot of digging', you're flying blind. You might be running your most profitable work at a discount and your loss-makers at full tilt — and repeating both.
The fix: track actual cost per job (labour + materials + overhead) against the quote, automatically. Once you can see margin by job, the pattern jumps out fast.
2. Your quotes are based on gut feel
An estimate of 'about 40 hours' — based on what? If your numbers come from memory rather than history on similar jobs, you're guessing, and guesses skew optimistic. Underquoting is the single most common way workshops give margin away.
The fix: quote from real history. When you know your last three similar jobs averaged 52 hours, you stop quoting 40.
3. Rework happens but nobody tracks it
Rework is double cost — the original hours plus the redo — and in most workshops it's invisible. It gets absorbed into the job total and never measured, so the root causes never get fixed and the same mistakes cost you again next month.
The fix: log rework as its own category. Once you can see it costs (say) 6% of total labour, you can attack the recurring causes.
4. You're still on paper timesheets (or none at all)
Paper timesheets are 15–30% inaccurate — filled in from memory at the end of the day or week. If your job costs are built on that data, they're wrong by the same margin. And wrong cost data means wrong quotes, on repeat.
15–30%
Typical inaccuracy in paper-based time tracking
The fix: capture time at the point of work — workers clock onto jobs and tasks live from the floor.
5. Your best people spend hours on paperwork
If your most skilled (and expensive) staff are chasing timesheets, re-keying data, and hunting job status, you're paying trade rates for admin. That's margin walking out the door in the most expensive way possible.
The fix: automate the data capture so the information builds itself and your people stay on the tools.
6. You find out a job's late when it's already late
If the first sign of a blown deadline is the deadline itself, your scheduling is reactive. Late jobs mean overtime, expedited materials, and unhappy customers — all margin killers, all avoidable with earlier visibility.
The fix: track job progress live against the schedule so a job running behind shows up days early, while you can still do something about it.
7. Overheads have grown but your charge-out rate hasn't
Rent, power, insurance, and equipment costs creep up every year. If your loaded labour rate hasn't been recalculated to match, you're quietly absorbing those increases out of margin on every single job.
The fix: recalculate your overhead recovery rate annually and feed it into your charge-out rate.
Plugging the leaks
Notice the pattern: every one of these comes back to visibility. You can't fix what you can't see, and margin leaks survive precisely because they're invisible. Get accurate job and labour data flowing, and the leaks stop being mysteries — they become a to-do list.
Workshops don't usually have a profit problem. They have a visibility problem that looks like a profit problem.
