JOBS THAT LOOK PROFITABLE UNTIL THEY DON'T.
Most subcontractors find out a job lost money at the end, when nothing can be done about it. The CFOS Job Profitability System tracks cost-to-complete and margin variance on every active job, every month, so you see a job going sideways at Week 4 instead of Week 22.
Job Profitability is Module 2 in CFOS, the Construction Financial Operating System. It connects your estimates to your actuals, builds overhead absorption into every job, and produces a weekly cost variance report by cost code. The goal isn't to explain what happened on a finished job. The goal is to change what you do on the job that's still running. Subcontractors that run margin-blind run overhead-blind too. They find out their overhead rate was wrong after the year is over and the damage is done. This module closes that loop in real time.
WHAT ACTUALLY BREAKS WITHOUT THIS.
Overhead Leakage Into Every Job
If your overhead rate is wrong (even by 3%) you're pricing jobs to break even while believing you're profitable. A concrete contractor doing $4.9M with a 14% overhead estimate when actual overhead runs 19% is giving away $245K per year without knowing it. The estimate looks good. The P&L looks good until it doesn't. By the time the CPA catches it at year-end, the jobs are done and there's nothing to recover.
No Mid-Job Course Correction
Labor runs 12% over in Week 3. Nobody sees it. The PM keeps pushing. By Week 10, labor is 19% over and the job has a $47K hole that can't be filled with productivity improvements. A job cost system that only reports at closeout is not a job cost system. It's a post-mortem. CFOS runs cost-to-complete projections weekly so the decision to add crew, change methodology, or issue a change order happens when it can still matter.
Estimates That Don't Match Cost Codes
The estimator builds the bid in one structure. The bookkeeper codes costs against a different structure. Nobody reconciles them. You end up with a job cost report that shows $0 in the "concrete placement" code and $180K in "miscellaneous labor", and the comparison to estimate is meaningless. CFOS aligns cost codes to the estimate structure on Day 1 of onboarding, so the comparison actually compares.
WHAT OWNERS THINK IS WRONG VS WHAT IS.
"Our jobs are profitable, we just need more of them."
Volume is not a substitute for margin visibility. A civil contractor doing 12 jobs simultaneously with no per-job profitability tracking isn't running 12 profitable jobs, they're running 12 jobs that look profitable in aggregate until one bad one destroys the year. CFOS has seen $7M subcontractors lose $400K on a single untracked job that was visible the whole time, just to nobody who was looking.
"We track costs in QuickBooks."
QuickBooks records what was paid. Job profitability requires cost-to-complete projection, overhead absorption by job, and comparison against the original estimate by cost code. QuickBooks doesn't do those three things. ControlQore does. The difference isn't the software, it's whether you're looking backward at costs or forward at remaining margin.
"The PM would know if a job was going sideways."
The PM knows the field is running hot. They don't know the job cost number. Most PMs have never seen the cost-to-complete on their own jobs because nobody gives it to them. CFOS produces a weekly job cost variance by cost code (in a format a PM can read without an accounting degree) so the person closest to the problem has the information to act on it.
SPECIFIC OUTPUTS. NOT ADVICE.
Proof it works: A $4.9M concrete contractor had been running a 19% overhead rate on jobs estimated at 14%. CFOS Job Profitability identified the discrepancy in the first 30 days, rebuilt the overhead rate, and repriced forward bids. Margin recovered $340K in the following 12 months. See the case study →
JOB MARGIN BLINDNESS IS TRADE-SPECIFIC.
Concrete & Flatwork
Material variance kills margin on concrete jobs. A 10% overage on ready-mix on a 4,000 CY pour is $18K–$28K gone before the job closes. Without a weekly cost-to-complete, nobody sees it until the job is poured and the check is already written.
Civil & Grading
Equipment cost absorption is the civil contractor's biggest job profitability problem. Equipment shows up in overhead and in direct cost simultaneously, and when it's misallocated, every job's margin is wrong. CFOS builds equipment cost flow into the cost code structure at setup.
Electrical (Commercial)
Change order tracking is the difference between a 12% margin electrical job and a 7% margin electrical job. Electrical work accumulates T&M and directed changes that never make it into a formal CO. CFOS installs a change order tracking log that runs alongside the job cost report.
Masonry & Framing
Labor productivity variance on masonry and framing jobs compounds fast. A 5% productivity miss in Week 2 becomes a 14% miss by Week 6 because crews adapt to the pace instead of correcting it. Weekly variance reporting catches productivity problems before they become permanent job cost overruns.
