Job costing

Job costing is the practice of tracking every cost tied to a specific job or project — labour, materials and a share of overhead — so you can see exactly what each one earned or lost.

How it works

• Costs are tagged to a job as they land: hours worked, materials bought, subcontractor invoices, equipment time.
• Each job carries its own running total, compared against what the customer was billed.
• The gap between the two is the job’s real margin — not the blended average across the whole business.

Unlike blanket profit, job costing tells you which work actually pays.

Why it matters

For anyone running discrete projects — a build, a fit-out, a client engagement — averages lie. One job can quietly subsidise a loss-maker for months, and without per-job numbers you keep taking on the wrong work. Materials bought against the wrong job, or supplier invoices that drift from the quote, erode margins you never see leaking.
