What does a job card actually cost you?
Ask a workshop owner what they quoted on a job and you'll get an answer in seconds. Ask what the job actually cost — materials really drawn, hours really worked, rework included — and the room usually goes quiet. Somewhere between the quote and the invoice, the truth went missing.
That gap is not a rounding error. Multiply it across a year of jobs and it's often the difference between a good year and a break-even one.
Where the money leaks
The classic paper-and-spreadsheet setup loses cost information in the same few places, every time:
- Unbooked hours. The job took a day and a half; the card says a day. Nobody lies — the card just gets filled in from memory at knock-off.
- Material drift. Offcuts, substitutions, the extra sheet that got spoiled — drawn from the store, never written against the job.
- Rework. The job that came back gets fixed on the company's time, invisibly.
- Quoting from memory. Next quote uses last year's rates and the same optimistic hours — so the leak repeats.
None of these show up on an invoice. That's what makes them expensive.
What "knowing" actually looks like
Proper job card software doesn't ask people to remember — it captures cost at the source:
- The quote is priced from the product's bill of materials and live rates, so the target is honest to begin with.
- Materials are scanned out of the store against the job — the stock system and the job agree because they're the same record.
- Hours land on the step that used them, so you can see which operation blows the estimate.
- At the end, quoted vs actual sits side by side, line by line — and every figure drills down to the transactions behind it.
The point isn't reporting for its own sake. Caught mid-job, a drifting cost is fixable. Caught at year-end, it's just bad news with a date on it.
The question worth asking this week
Pick your last five completed jobs and try to answer, honestly: did each one make money? If the answer takes more than a few minutes — or comes back "more or less" — the information exists in your business; it's just not being captured where it happens.
That's a fixable problem, and it's exactly the kind of manufacturing and job card software we've been building for South African operations for 30 years.
