What is the difference between job costing and regular accounting?
Regular accounting tracks your business as a whole. You see total revenue, total expenses by category, and overall profit or loss. Your financial statements tell you whether the business made money last month, but they don’t tell you which projects contributed to that profit and which ones dragged it down.
Job costing breaks every cost down by project. Labor hours, materials, subcontractor invoices, and equipment costs all get assigned to specific jobs. Instead of just knowing your business made $40,000 profit last quarter, you see that the Smith remodel made $18,000, the Johnson addition made $25,000, and the Wilson project actually lost $3,000.
That level of detail changes how you run your business.
With regular accounting, you might think everything is fine because the bank account is growing. But you could be losing money on certain project types while other jobs carry the business. You won’t know until you’re stuck with unprofitable work and none of the jobs that actually make money.
Job costing shows you which jobs make money and which don’t. You can see if your estimates are accurate by comparing budgeted costs to actual costs for each phase. You can identify which project types to pursue and which to avoid. You catch cost overruns while there’s still time to react instead of finding out after the job is done.
For contractors, job costing isn’t optional if you want to know your real margins. Regular accounting works fine for businesses selling the same product or service repeatedly at consistent margins. But when every project is different with different scope, site conditions, and subcontractors, you need project-level visibility to make informed decisions.
The difference isn’t just how costs get categorized. It’s whether your financial data helps you run the business or just tells you what happened after the fact. A bookkeeper in American Fork who understands construction can set up your books to track both, giving you the overall business view and the job-level detail you need to bid accurately and protect your margins.
