Business Risk Cue
A choice that increases financial exposure, cash-flow risk, or profit erosion if left unaddressed.
Project 18
Build and operate one job-cost and profitability review process that compares original estimate, contract value, approved changes, committed cost, actual cost, labor hours, material, equipment, subcontractors, overhead recovery, revenue, cash, gross profit, variance, and forecast on an active or recently completed residential project, and that feeds lessons learned back into Chapter 6 scope and Chapter 7 pricing.
These cues appear at the point of work. They identify compliance, professional-review, financial-control, and documentation issues before an unreviewed job-cost figure is treated as a fact.
A choice that increases financial exposure, cash-flow risk, or profit erosion if left unaddressed.
An action that must not be taken, or must be stopped, until a specific accounting, contract, or authorization condition is satisfied.
Practical controls that keep the job-cost record honest as the project is actually built and billed.
Tax, retainage, trust-fund, and lien-related accounting treatments vary by jurisdiction. Verify current requirements before relying on this chapter.
A point where the CPA, bookkeeper, or accounting system administrator must be consulted before a cost, revenue, or tax treatment is finalized.
A figure, comparison, or decision that must be written down, dated, and retained in the job-cost record.
This project produces one operating job-cost and profit review process for a residential contracting business. The finished work product is a controlled job-cost record for at least one sample project, built and tested against the estimate, contract, changes, commitments, actual costs, revenue, and cash position for that job, together with a variance-investigation procedure, threshold alerts, a periodic review cycle, and a final reconciliation and lessons-learned procedure.
You will import the original estimate and contract value, create committed-cost and actual-cost records, reconcile labor hours and production, compare material and equipment cost and use, track subcontractor commitments and invoices, separate profit from cash flow, calculate forecast cost to complete and forecast gross profit, identify and investigate variance by cause, create corrective actions, complete a final job-cost reconciliation, and record lessons learned for pricing and scope.
This project depends directly on the Chapter 5 accounting system, the Chapter 7 pricing worksheet, and the Chapter 10 change-order and allowance system. It supplies the actual-cost feedback that Chapter 7 pricing and Chapter 6 scope assumptions require, and it supplies the financial reconciliation that Chapter 19 closeout and the Chapter 20 capstone depend on.
This project builds directly on the Chapter 5 banking and accounting system, the Chapter 7 pricing worksheet, and the Chapter 10 change-order and allowance system. Without a working chart of accounts and cost-code structure from Chapter 5, and without an accurate original estimate from Chapter 7, a job-cost comparison has nothing reliable to compare against.
The job-cost record built here is the financial spine that the Chapter 13 job-start packet initializes, the Chapter 14 customer-communication process references when discussing changes and delays, and the Chapter 19 final walkthrough and invoice depend on for a correct final account. The variance-investigation discipline used here — identify, confirm, correct, reinspect — is the same discipline used throughout the book's troubleshooting sections and is required again in the Chapter 20 capstone operating system.
This project covers:
This project does not authorize the learner to:
Any job-cost figure that has not been reconciled against the accounting system of record must be labeled as preliminary until it is confirmed.
Establish these references before building the comparison worksheet, and do not change their meaning mid-document.
| Term | Definition |
|---|---|
| Original estimate | The approved Chapter 7 pricing-worksheet cost, hours, and profit for the job as contracted |
| Contract value | The original contract sum plus every approved Chapter 10 change and less every approved credit, to date |
| Committed cost | Cost obligated through an issued purchase order, subcontract, or rental agreement but not yet invoiced |
| Actual cost | Cost posted in the accounting system for payroll, materials, equipment, subcontractors, permits, fees, delivery, disposal, and expenses on the job |
| Forecast cost to complete | The estimated remaining cost, by cost code, needed to finish the unperformed scope |
| Forecast final cost | Actual cost to date plus committed cost plus forecast cost to complete |
| Forecast gross profit | Contract value minus forecast final cost |
| Gross margin | Forecast gross profit divided by contract value, using the company's approved consistent formula |
| Variance | The difference between original estimate and actual or forecast cost for a given cost code, stated as a dollar amount and a probable cause |
Before the comparison worksheet is built, record the following directly on the Job-Cost Comparison Worksheet template:
Job number: ______ Customer: ______ Estimate revision used: ______
Review date: ____________ Reviewer(s): ____________ Accounting data through date: ____________
Every job-cost review compares the same four things, in the same order, regardless of trade or project size: what was estimated, what has been committed and spent, what remains to be spent, and what that leaves for profit. Skipping the committed-cost step, mixing cash received with profit earned, or comparing total hours instead of hours by task are the most common ways this comparison gives a false answer.
A variance is only recorded as explained after its probable cause has been confirmed against a specific source — a timekeeping record, a purchase-order price, a change-order log, or a field report. A variance may not be closed as "estimating error" merely because no other cause was checked first.
When a cost code shows a variance in Section H, record the cost code, the dollar amount, the probable cause from the approved list, the confirming source, and the corrective action. Do not simply note that the job is over or under budget without identifying which cost code and which cause.
Overhead recovery embedded in the contract price covers the company's actual overhead cost; it is not additional net profit. Do not report forecast gross profit to management, ownership, or a lender as net profit without full financial review by the CPA.
Complete the periodic active-job review defined in Section H beginning at the first billing cycle after mobilization. Do not wait until substantial completion or final invoice to run the first job-cost comparison.
Revenue-recognition method, retainage treatment, and cost-to-complete accounting affect how gross profit is calculated and reported. Confirm the approved method with the CPA before comparing job-cost figures across multiple projects or reporting them externally.

Financial Control / Job-Cost Review
Quantity: one completed Job-Cost Comparison Worksheet for the sample project, one Variance Log with every identified variance and its cause and corrective action, one Lessons-Learned Record, and one periodic-review schedule with responsible owner and cadence, all dated and reviewed by the bookkeeper, CPA, estimator, and project manager as applicable.
| Document | Quantity | Format | Content Required | Preparation / Purpose |
|---|---|---|---|---|
| Job-Cost Comparison Worksheet | 1 per active job | Multi-column cost-code table | Estimate, committed, actual, forecast, and variance by cost code, plus revenue, cash, and gross profit | The controlling comparison document referenced at every review |
| Variance Log | 1 per job, ongoing | Log with running entries | Cost code, amount, probable cause, confirming source, corrective action, status | Tracks every identified variance from discovery to resolution |
| Lessons-Learned Record | 1 per completed job | Structured summary | Findings by scope, estimating, production, supplier, subcontractor, customer, schedule, quality, and warranty category | Feeds approved updates back to Chapter 6 and Chapter 7 |
| Periodic-Review Schedule | 1, company-wide | Calendar with owners | Review cadence, responsible reviewer, and escalation threshold for every active job | Ensures review happens before, not only after, completion |
| Check | Standard |
|---|---|
| Estimate-to-actual comparison | Every cost code on the worksheet shows original estimate, committed cost, actual cost, forecast cost to complete, and variance |
| Labor reconciliation | Actual hours are reconciled to job, cost code, date, and supervisor, with no unassigned or unexplained time |
| Material and equipment reconciliation | Purchase quantity, use, waste, return, and credit are compared to estimated quantity for every material cost code reviewed |
| Variance documentation | Every variance beyond the company's approved threshold has a recorded probable cause, confirming source, and corrective action |
| Profit and cash separation | Forecast gross profit and cash position are calculated and reported as two distinct figures, never combined |
| Periodic review | At least one periodic review has been completed on the sample job before substantial completion, in addition to the final review |
| Lessons learned and feedback | Findings are categorized, and any proposed update to Chapter 6 or Chapter 7 is routed for management approval before it is applied |
Inspect the completed job-cost process using the same checks regardless of which job or trade is involved.
Complete the Job-Cost Review Approval Worksheet in the Inspection Checklist section below before beginning Project 19.
Probable cause: committed cost from open purchase orders or subcontracts was not included in the periodic comparison, so only posted invoices were counted as cost.
Confirmation: compare the forecast final cost calculated with committed cost included against the actual final cost after all invoices post.
Correction: add committed-cost records to every future periodic review before calculating forecast final cost.
Reinspection: repeat the comparison check on the corrected worksheet for the next active job.
Probable cause: timekeeping entries were coded to the job but not to a specific task or cost code, so total hours cannot be compared by task.
Confirmation: review a sample of timesheet entries for the job and check whether each entry identifies a task-level cost code.
Correction: correct the timekeeping procedure to require task-level coding and recode the affected entries where possible.
Reinspection: repeat the labor-reconciliation check on the next periodic review.
Probable cause: the variance was closed without checking the change-order log, purchase-order price, or field report that might explain it.
Confirmation: check whether a confirming source is recorded for the variance entry in the Variance Log.
Correction: reopen the variance, check it against the change-order log, purchase-order price history, and field reports, and record the confirmed cause.
Reinspection: repeat the variance-documentation check before the entry is closed again.
Probable cause: the worksheet combined the profit and cash-flow figures into a single reported number.
Confirmation: check whether the worksheet presents forecast gross profit and net cash position as two separate lines.
Correction: separate the two figures on the worksheet and correct any prior report that combined them.
Reinspection: repeat the profit-and-cash-separation check before the next report is issued.
Probable cause: the allowance register from Chapter 10 was not cross-checked against committed cost during the periodic review.
Confirmation: compare each allowance's committed amount on the Chapter 10 log to its original amount as of the last periodic review date.
Correction: add the allowance cross-check to every future periodic review and notify the customer of any overrun as soon as it is identified.
Reinspection: repeat the allowance-exposure check on the next periodic review.
Probable cause: a lessons-learned finding was entered directly into the Chapter 7 pricing worksheet or Chapter 6 scope library without routing it for review.
Confirmation: check the Lessons-Learned Record for a recorded management approval date corresponding to the applied change.
Reinspection: revert the unapproved change, route the finding through management review, and reapply it only if approved.
Reinspection: repeat the feedback check before the next pricing or scope revision cycle.
This project ends with the completed job-cost documents filed for reuse, not left as a one-time spreadsheet exercise.

Reviewing professional(s): ____________ Next scheduled periodic review date: ____________
With the comparison worksheet, variance log, and lessons-learned record completed, review the finished process against the Acceptance Standards table and confirm every cost code shows estimate, committed, actual, forecast, and variance figures, labor and material are reconciled by task rather than only in total, every threshold variance has a confirmed cause and corrective action, forecast gross profit and cash position are reported as separate figures, at least one periodic review occurred before substantial completion, and lessons learned are categorized with any proposed pricing or scope update routed for management approval. Complete the Job-Cost Review Approval Worksheet and correct any failed item before beginning Project 19. If an item fails, identify whether the gap is in data import, cost reconciliation, variance investigation, forecast calculation, review timing, or feedback routing before revising the process.
You have completed the eighteenth project in the professional-contractor sequence: creating a job-costing and profit review process. This project required you to track estimated versus actual cost (PC-103), review labor hours (PC-104), review material costs (PC-105), identify overruns and their causes (PC-106), calculate gross profit and forecast cost to complete (PC-107), and document lessons learned (PC-108).
You now have one tested Job-Cost Comparison Worksheet, a Variance Log with documented causes and corrective actions, a Lessons-Learned Record, and a periodic-review schedule. These records carry directly into the next project: completing the final walkthrough, punch list, invoice, and warranty handoff, which depends on the reconciled final account this job-cost process produces.
Store your completed Job-Cost Comparison Worksheet, Variance Log, and Lessons-Learned Record in the job file. You will reference these exact records when preparing the final invoice in the next project.
