JOB COSTING

WHY PMS BREAK JOB COSTING.

QUICK ANSWER

Job costing fails in the field long before it fails in the books. PMs code costs to the wrong job, estimate percent complete by schedule instead of by cost burn, absorb change order work without triggering a billing event, and approve invoices against the wrong cost codes. The financial system only knows what the PM puts into it.

None of this is intentional. A PM's job is the job: the crew, the schedule, the GC, and the inspector. The financial structure underneath it's somebody else's system as far as the PM is concerned, and it stays that way until somebody sits down and explains what the system needs from them. Every number the CFO reports on a job traces back to a PM input, whether that's the coding, the percent complete, or the change order billing. Fix the inputs and the reports fix themselves. Rebuild the reports without fixing the inputs and you get the same wrong answers faster.

THE DEFINITION

WHAT IT MEANS.

Field to financial alignment is the practice of mapping every cost code in the estimate to its job cost code before mobilization, so the PM knows where every receipt, invoice, and labor charge belongs.

The reporting chain runs in one direction. The PM codes the cost, the bookkeeper processes what was coded, the controller closes what was processed, and the CFO reports what was closed. Every step downstream inherits whatever the first step got wrong, which is why fixing job costing inside the accounting software almost never works on its own.

FOUR WAYS PMS CORRUPT JOB COST DATA

WHERE THE DATA GOES BAD.

01

Coding costs to the wrong job

A material delivery comes in for Job B while the PM is running Job A. The invoice gets coded to Job A, because Job A is what was open on the screen. Job A's costs are overstated and Job B's costs are understated, so both job margins are wrong. Nobody catches it until closeout, if anybody catches it at all.

02

Percent complete by schedule

The PM says 60 percent complete because 60 percent of the schedule is done. Meanwhile 74 percent of the labor budget has burned. The cost to complete reads fine and the WIP reads fine. The job is heading for a loss and nothing in the reporting system flags it, because the PM's input drives everything downstream of it.

03

Change order work without a billing trigger

The GC approves a verbal change order and the PM directs the crew to proceed. The costs hit the job and nobody submits the change order billing. Three weeks later the PM remembers it, and by then the leverage window is closing. The job has been showing a false loss for weeks, because the cost posted with no revenue to match it.

04

Approving invoices without checking cost codes

The PM approves an invoice and the cost code field says misc overhead. The PM doesn't catch it, the bookkeeper processes it, and that cost goes to overhead instead of to the job it belongs to. Overhead reads worse and job margin reads better, so both numbers are wrong. The PM was the last checkpoint and waved it through.

WHAT FIELD TO FINANCIAL ALIGNMENT LOOKS LIKE

THREE THINGS THAT CHANGE.

The alignment meeting, before the job starts

Before mobilization, the PM, the CFO, the controller, and the estimator get in one room. Every cost code in the estimate gets mapped to its job cost code, every cost category gets explained, and every approval workflow gets confirmed. The PM leaves knowing where every receipt, invoice, and labor charge belongs. That happens before day one rather than after the first month closes.

The change order trigger protocol

Every scope change, verbal or written, triggers a change order document before the work starts rather than after it. The leverage exists before the work is done. The PM understands that work performed without a billing event is free work. The CFO tracks open change orders monthly and flags any that carry costs with no billing against them.

The monthly job cost scorecard review

Every PM reviews their job cost scorecard after close: actual spend by cost code against estimate. It's not a summary and it's not a blended job total. It goes cost code by cost code, with the CFO in the review. When a code is trending over, the PM explains why and what's being done about it, and that review is what turns PM accountability from an idea into a practice.

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.

PMs code costs to the wrong job, estimate percent complete by schedule instead of by cost burn, proceed on change orders without a billing event, and approve invoices without checking cost codes. None of it's intentional, because PMs focus on the job itself rather than on the financial structure underneath it. The financial system depends on what the PM puts in, so the outputs reflect the quality of field discipline.
There are three routines. An alignment meeting before the job starts where every cost code gets mapped and every approval workflow gets confirmed, a change order trigger protocol that fires before scope work starts rather than after it, and a monthly job cost scorecard review where the PM walks through actual against estimate by cost code with the CFO in the room.
The alignment meeting happens before mobilization, with the PM, the CFO, the controller, and the estimator in one room. Every cost code in the estimate maps to its job cost code and every approval workflow gets confirmed. The PM leaves knowing where every receipt, invoice, and labor charge belongs. It's the difference between a job cost structure that gets followed and one that gets guessed at.
Yes, and they need support to do it. The PM is the last checkpoint for every cost that hits the job, because they approve invoices, submit percent complete, and track change orders. The CFO's job is to train PMs on what the financial system needs, build a review process that catches the misses, and create accountability through the monthly scorecard review.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books.
