Construction Job Costing
Project-level tracking of labor, materials, and subcontractor costs so you know which jobs make money and which don't.
What This Is
Construction job costing is the practice of tracking every dollar spent against a specific project. Labor hours, materials, subcontractor invoices, equipment usage, and permits all get coded to the job they belong to. The result is a project-by-project view of your business instead of a single lumped-together profit and loss statement.
Dennis spent years inside real estate development firms building exactly these systems. Project costing, construction draw packages, budget versus actual tracking, and reforecasts at the job level. The same discipline that institutional developers use to keep multi-million dollar projects on budget applies directly to the contractors and builders working across Los Angeles County.
The Setup
The Setup
We build out your job list inside QuickBooks or whatever platform you use, establish cost codes that reflect how you actually run projects, and set up the workflows to capture labor, materials, and subcontractor costs at the job level. Change orders and retention get tracked separately so nothing slips through.
The Reporting
The Reporting
Monthly job profitability reports showing revenue, costs, and margin by project. Work-in-progress summaries for open jobs. Budget versus actual comparisons on projects where you bid with a detailed estimate. Completed job analysis so you can learn from each one before bidding the next.
Why It Matters
Contractors without job costing are flying blind on the single question that matters most. Not whether the business made money this month, but which jobs made money and which didn’t. The overall number tells you nothing useful when three profitable jobs are covering for two that lost money.
Cash flow compounds the problem. A large deposit from a job you haven’t started yet can make the bank balance look healthy even when recent work has been unprofitable. By the time the cash runs out, the losing jobs are already complete and you’ve been bidding new work using the same flawed assumptions that produced the losses in the first place.
Bidding Without Data
Bidding Without Data
If you don’t know what the last three bathroom remodels actually cost to build, your next bid is a guess. Labor hours get underestimated. Material waste gets ignored. The cost of going back for punch list items never shows up in the estimate. You win the job and lose money on it without understanding why.
Late Discoveries
Late Discoveries
A subcontractor invoice arrives six weeks after you closed the job out mentally. A material cost you forgot to allocate shows up in a reconciliation. Without a system tracking costs against the specific project, these late charges disappear into the general ledger and your profit numbers stay wrong.
What Changes
You start seeing your business at the job level. Which project types consistently produce margin. Which clients are worth pursuing. Which subs come in on budget and which run over. These are the details that separate contractors who grow profitably from contractors who stay busy but never seem to have cash on hand.
Bidding becomes grounded in real numbers from real jobs you actually completed. When a client asks for a proposal on a kitchen remodel, you have the cost history from similar jobs in front of you. Labor hours that reflect what the crew actually spent, not what you hoped they would spend. Material costs that account for the waste and the returns. The bid reflects reality.
Estimates Backed By History
Estimates Backed By History
Every completed job becomes a reference point for the next one. Over time you build a library of actual cost data across job types, crew configurations, and project sizes. Your estimators stop guessing and start calibrating against jobs you already finished.
Decisions You Can Defend
Decisions You Can Defend
Which customer segments deserve more of your time. Whether to expand into a new type of work. How to price a change order. With job-level data you answer these questions from a position of knowing, rather than guessing based on which project feels like it went well.
