JOB COSTING · 18 GUIDES

YOU CANNOT MANAGE WHAT YOU CANNOT SEE.

QUICK ANSWER

Job costing compares actual cost against estimated cost by individual job, using cost codes that mirror how the bid was assembled. The setup counts as much as the discipline: if the codes don't match the estimate there's no honest comparison to make. It fails for three reasons, and all three are structural rather than a shortage of effort.

The part worth sitting with is the word structural. Cost codes built by an accountant who never read an estimate produce a report comparing two things that were never assembled the same way, and no amount of field discipline rescues that. So the pages in this hub run from setup and code design through committed cost, cost to complete, production tracking, and the project managers who have to live inside the system. Get the structure right and the discipline gets easy, because a report that tells a superintendent something he can act on is a report he will keep feeding.

THE DEFINITION

WHAT IT MEANS.

Job costing is the practice of comparing actual cost against estimated cost for one individual job, using cost codes that mirror the way the estimate was built, so a problem is visible while the job can still be corrected.

THE MECHANISM, NOT THE SYMPTOM

WHY IT BREAKS.

01

Cost Codes Do Not Match the Estimate

When the tracking structure doesn't mirror the bid structure, there's no honest way to compare actual cost against what the job was supposed to cost. The report still produces numbers, and the numbers still add up to the job total, but no line in it answers the question the estimator asked. Most job costing that gets abandoned was never comparable in the first place.

02

Field Data Comes In Too Late

Coding that posts a month after the work turns job costing into a historical record instead of a management tool. The window for correcting a phase closes while the report is still being assembled. A rate that's 30 percent over on week two is a conversation; the same rate discovered at closeout is a loss you already took.

03

Project Managers Do Not Trust the Report

A report that's slow, or wrong once, gets abandoned without anybody saying so. The PM goes back to running the job on judgement, which is often good judgement, and the system becomes something the office maintains for its own benefit. Trust is the deliverable, and it's earned by the report being fast and right and not by anybody being told to use it.

  1. Cost to Complete, How ToBuild remaining work line by line, match the percent complete method to each cost type, and run it monthly in 20 to 30 minutes a job.
  2. Job Costing StandardsCost codes mirroring the estimate, burden divided over 1,960 productive hours rather than 2,080, and costs entered inside 48 hours.
  3. Job Costing Explained for ContractorsSeven cost categories, why labor gets tracked in burdened dollars, and how a single labor code hides a phase running 22 percent over inside the same $187K.
  4. Job Costing SetupCost codes built from the structure your estimators already use, overhead allocated by a driver, and WIP logic matched to how you bill.
  5. Committed Costs vs Actual CostsCommitted cost is the full obligation whether the sub has invoiced you yet or not.
  6. Cost to CompleteThe estimate reflects the estimator's own performance, month three's optimism becomes month four's baseline, and percentage of completion overstates revenue.
  7. Equipment Cost in Job CostingSplit the machine, the operator, the fuel, and the fees into separate cost codes.
  8. Job Costing vs Real Job ProfitOverhead allocation, WIP accuracy and billing timing sit between what you spent and what you earned.
  9. Payroll Job Costing IntegrationLabor is the biggest number on the job and it posts a pay period late.
  10. PM Job Cost ScorecardA $296,000 job in month four projecting negative $10,200, with three months of schedule left to change it.
  11. PM Labor Cost AccountabilityThe green, yellow and red thresholds at 105 and 115 percent of earned value, and why 15 percent over on labor means the crew is producing at 87 percent.
  12. Production Tracking vs AccountingAccounting confirms the overrun six weeks after it became a field fact.
  13. Production Tracking SystemCost per unit says what cost per hour can't.
  14. Unit Cost TrackingThat variance is knowable while the phase is open.
  15. Why PMs Break Job CostingJob costing fails in the field before it fails in the books.
  16. Davis-Bacon Job CostingBurden comes off the wage determination, not private work history.
  17. Field Production vs Job CostingA $4K second access point saved a projected $47K labor overrun because the weekly report flagged it in week three.

Range reflects the three tiers below. Which one you're in depends on how much of the work you want off your desk. No payroll. No hidden line items.

Core

You stop guessing.

You get the CFO work. Job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a meeting every month that ends in decisions rather than a report.

Your bookkeeper keeps doing the books.

Executive

You stop touching the books.

Everything in Core, and we run the bookkeeping and the controllership as well. Nobody in your office is answering coding questions or chasing a reconciliation at month end.

We do the books. No payroll.

Strategic

Every job shows its margin while it's still running.

Everything in Executive, plus the job costing and WIP platform set up, loaded with your cost codes, and managed for you every month. You never have to learn it.

We do the job costing.

COMMON QUESTIONS

FREQUENTLY ASKED.

Job costing tracks actual cost against estimated cost, by individual job, using cost codes that mirror how the estimate was built. Done properly it shows whether a job is profitable during execution rather than at closeout, which is the only point at which the answer is still useful.
Usually because the cost codes don't match the estimate structure, or because field data comes in too slowly to act on. Either one makes the report unable to answer the question a project manager is asking, and a report that can't answer the question gets abandoned.
Bookkeeping records what happened at the company level and closes the month. Job costing tracks cost at the project level while the project is running, so a phase that's over can be corrected before it compounds into the next one. A company can have flawless books and no idea which jobs make money.
