HOW A CONSTRUCTION CFO MANAGES JOB COST TRACKING.

QUICK ANSWER

A bookkeeper enters costs into cost codes. A CFO manages costs against estimates, compares actual to budgeted at the phase level, tracks cost-to-complete weekly, and flags variances before they compound. The difference between those two functions is the difference between a job costing system that produces data and one that produces decisions. Most subcontractors have the first. Almost none have the second.

Job costing without a CFO layer is a filing system. It tells you what happened after the fact. Job costing with a CFO layer is a management tool. It tells you what is going to happen while there is still time to change it.

Weekly
Job Cost Review Frequency
CFOS runs a weekly job cost scorecard for every active job. Not monthly. Not at closeout. Weekly — while there is still job left to manage.
30%
Review Trigger Point
Job cost review at 30% completion is the earliest point where variance data is meaningful and margin compression is still recoverable.
Phase Level
Required Granularity
Top-level job cost categories are not enough. Labor by phase, material by type, equipment by piece. Phase-level tracking is where the variance lives.
ENTERING VS MANAGING
The Gap Between Bookkeeping and CFO-Level Job Costing

A bookkeeper enters a concrete delivery invoice into the material cost code for job 112. The entry is correct. The cost is in the right place. The job costing system now has accurate data. What happens next is where the gap appears.

A CFO looks at that entry against the material budget for job 112. The concrete delivery is $18,000. The material budget for this phase is $14,500. There is a $3,500 variance. Why? Was the scope different? Did prices change? Was there a change order that was not captured? That question gets asked this week — not at job closeout when there is nothing left to do about it.

COST-TO-COMPLETE IS THE CRITICAL INPUT
Why the PM's Weekly Estimate Changes Everything

The most important number in any job cost system is not what has been spent. It is what remains to be spent. Cost-to-complete is the PM's current best estimate of what it will cost to finish the job from today. That number, combined with costs incurred, produces the projected final cost — and the projected final margin.

A CFOS engagement builds cost-to-complete into the weekly PM scorecard. Every Friday, every active job has a projected final margin based on that week's field reality. When a job is projecting 14% margin instead of the 23% estimated, that is a problem that gets addressed in week 6 — not week 14.

VARIANCE ANALYSIS IS NOT AN ACCOUNTING FUNCTION
Why CFO Involvement in Job Reviews Changes Outcomes

When an accountant sees a labor variance, they document it. When a CFO sees a labor variance, they ask why and what is being done about it. That distinction changes the outcome of every job review meeting. The CFO who brings a week-6 job cost scorecard showing 8% labor overrun to a PM meeting is producing a decision — not a report.

CFOS structures monthly job reviews as accountability meetings. The PM presents cost-to-complete. The CFO presents variance analysis. The owner asks one question: what are we going to do about it. The answer determines whether the job recovers or fades.

01
WEEKLY PM JOB COST SCORECARD
Every active job gets a one-page Friday scorecard: costs incurred by phase vs budget, cost-to-complete updated by PM, projected final cost, and current gross margin forecast. This is the number that changes PM behavior. Not the month-end P&L — the weekly scorecard that shows the trend while the job is still running.
02
PHASE-LEVEL COST CODES ALIGNED TO ESTIMATES
Job cost codes must match estimate line items exactly. When a civil PM estimates earthwork at $140,000 in three phases, the job costing must track those same three phases. If estimate phases and cost code structure differ, there is no apples-to-apples comparison and the variance analysis is noise.
03
30% COMPLETION JOB REVIEW — MANDATORY
The 30% completion review is the inflection point. At 30%, there is 70% of the job left to run. A cost-to-complete showing margin compression at 30% complete is recoverable. The same information at 90% is a post-mortem. CFOS mandates this review on every job regardless of apparent health.
04
CHANGE ORDER CAPTURE IN THE WEEK IT HAPPENS
Every scope change gets documented and priced in the same week it occurs. Not at month-end. Not when the PM gets around to it. The week it happens. Change orders that slip into the following month's pay app represent 30 days of float on cash that is already earned. CFOS tracks open change orders weekly alongside job costs.

COMMON QUESTIONS

FREQUENTLY ASKED.

A bookkeeper enters costs correctly into cost codes. A CFO compares those costs to the estimate at the phase level, tracks cost-to-complete weekly from the PM, identifies variances before they compound, and runs job review meetings where the PM is accountable to the numbers. The bookkeeper produces accurate data. The CFO produces decisions from that data.
Weekly for cost-to-complete updates from the PM, and formally at 30% and 60% completion with the owner, PM, and CFO in the same room. The 30% review is where margin compression is still recoverable. The 60% review is the last point where redeployment or change order capture can materially change the outcome.
Cost-to-complete — the current best estimate of what it will cost to finish the job from today. Not what the original estimate said. Not a percentage of schedule complete. The PM's current field-based estimate of remaining cost. That number combined with costs incurred produces the projected final margin. It is the only number that tells you where the job is going while there is still time to change course.
