Accounting · Job costing
Company-wide profit is comforting. Job-level profit is the truth.
A profitable year can hide unprofitable jobs — and one bad job can disguise a great one. TechBrot’s Certified QuickBooks ProAdvisors set up job costing the right way, allocate labor and overhead correctly, and produce WIP and job-profitability reporting — so you know which projects make money and which ones quietly cost you. Independent firm, not affiliated with Intuit Inc.
Job costing is the practice of tracking revenue and cost to each individual job, project, or work order — so labor, materials, subcontractors, equipment, and overhead all get assigned to specific jobs and each project produces its own P&L. TechBrot’s Certified ProAdvisors set up cost-code structure, payroll and burden allocation, and class/location tracking in your own QuickBooks file; handle change orders, retainage, and AIA billing where relevant; produce WIP schedules and job-profitability reports; and run it inside recurring monthly bookkeeping.

Job costing, in five questions.
What is job costing?
Tracking revenue and cost to each individual job — labor, materials, subs, equipment, overhead — so each project produces its own P&L. The discipline that lets a business answer “did this job make money” at close.
Who needs it?
Construction GCs, subs, and trades most; also engineering, architecture, agencies, consultancies, law and accounting practices billing on matters, and small manufacturers running custom work. Anyone whose company-wide P&L hides job-level truth.
How does it work in QuickBooks?
Customers and sub-customers (or Projects in QBO), item-based transactions mapped to revenue and cost accounts, class or location for extra dimensions, and payroll integration for labor allocation. Set up correctly, every transaction lands against its job automatically.
What is WIP reporting?
Work-in-progress: earned revenue versus billings on in-process jobs, with the variance recognized as over- or under-billing on the balance sheet. Essential for accurate financials, lender reporting, and bonding.
What does it cost?
Setup inside a QuickBooks setup or cleanup engagement, scoped to the business. Ongoing job-costing bookkeeping included in monthly bookkeeping ($400–$2,500+/mo with complexity), priced higher for active job volume, AIA, or certified payroll. No hourly billing.
Job costing, plainly.
Job costing is the practice of tracking revenue and cost to each individual job, project, or work order — instead of only at the company level. Labor, materials, subcontractors, equipment, and overhead all get assigned to specific jobs, so each project produces its own P&L and the only question that matters at job close — did this job make money — is actually answerable. Contractors, trades, and project-based service firms need it most, but agencies, law and accounting practices, and small manufacturers running custom work all benefit from the same discipline.

If any of these sound familiar, the company-wide P&L is lying to you.
Most operators reach for real job costing when the year-end number stops matching what their gut says about individual jobs.
You know jobs vary in profitability — you just can’t see by how much.
Everyone has “great jobs” and “bad jobs.” If you can’t name the dollar margin on each, you’re estimating — and the estimates are usually generous.
Labor isn’t allocated to jobs.
If payroll is one company-wide expense line, the biggest cost driver in your P&L isn’t tied to any project. Labor allocation is where most job-costing setups break down first.
Change orders aren’t tracked separately.
If change orders blend into the original contract, you can’t see scope creep, can’t see margin impact, and can’t learn anything from one job to the next.
Year-end margin surprises you.
If “we had a great year” and “we barely broke even” both feel plausible until the CPA tells you, the books aren’t producing a real-time read.
A lender or bonding company wants WIP.
Sureties and lenders for construction expect a real WIP schedule. “We’ll get back to you” signals weakness; clean WIP signals credibility.
Estimating doesn’t learn from actuals.
If you can’t compare estimated cost to actual cost by job, every new bid is a fresh guess. Job costing closes that loop.
What job costing actually delivers.
Six workstreams covering setup and ongoing bookkeeping — scoped to your industry and job volume.
Cost-code structure
An industry-appropriate cost-code structure — CSI divisions for construction, project phases for services, work-order routings for manufacturing — built into the chart of accounts and item list. Labor, materials, subs, equipment, and overhead each get a defined home, so every transaction has somewhere true to land.
Labor & burden allocation
Payroll integration so labor lands on the right jobs, with burden (payroll taxes, benefits, workers’ comp) allocated — so reported labor cost reflects reality, not just wages. Labor is the largest and most-mis-tracked cost driver on most jobs; getting it allocated is where job costing earns its keep first.
Materials, subs & equipment
Materials, subcontractor invoices, and equipment cost coded to jobs at bill entry — not assigned weeks later when the trail has gone cold. Committed costs and open purchase orders are visible against the job before the bill even arrives, so the cost picture is current, not retrospective.
Change orders & retainage
Change orders tracked separately against original contract value; retainage held back on both sides of receivables and payables, so the balance sheet reflects real exposure. Approved change orders flow into the contract value and surface in WIP and profitability — the single most common place margin quietly goes missing.
WIP & AIA billing
Work-in-progress schedules showing earned vs billed, over/under recognition on the balance sheet under percentage-of-completion, and AIA-style progress billing (G702/G703) workflows for contractors that need them. WIP is what lenders and sureties ask for — and what keeps over-billing from masquerading as profit.
Job-profitability reporting
Monthly reports showing margin by job and phase, estimated vs actual cost, top and bottom performers, and the patterns across jobs that change how you bid. The point of the whole exercise: a number you can act on, not a spreadsheet that sits unread.
Built for project businesses — in all their flavors.
Different industries call it different things. The discipline is the same.
General contractors & subs
The classic users. Cost-code structure, certified payroll where required, AIA billing, WIP, retainage — the full stack. See construction accounting.
Trades & specialty contractors
Electrical, mechanical, plumbing, HVAC, roofing — same project-by-project economics, often with service-and-project hybrid models. Job costing distinguishes one from the other so the service truck doesn’t subsidize the loss-making install.
Architecture, engineering & design
Hourly-billed and fixed-fee project work where labor is the dominant cost. Project profitability and utilization both depend on job-level cost tracking — without it, the fixed-fee jobs that overrun are invisible until year-end.
Agencies & consultancies
Marketing agencies, dev shops, management consultancies — project margin and utilization are the only numbers that matter. Job costing makes both visible, and turns “we’re busy” into “we’re busy on the profitable work.”
Professional services on matters
Law firms, accounting practices, and other professional services billing by matter or engagement — matter-level cost and realization is the same discipline by a different name. Which matters carry margin, and which write-downs repeat, become answerable.
Small custom manufacturers
Custom or made-to-order manufacturing where each work order has its own materials, labor, and overhead. Job costing replaces standard-costing assumptions with actuals — so the quote that loses money in production stops repeating.
From setup to reports you actually use.
Four phases, fixed fee, written scope. Once setup is done, job costing runs inside monthly bookkeeping.
Discovery
A 30-minute call to map your job types, billing model, cost structure, payroll setup, and whether AIA billing, certified payroll, or retainage apply. No pitch.
Setup
Cost-code structure, item-list, payroll allocation, class or location tracking, WIP method — designed and built. Where existing books need restructure, that’s included or scoped as cleanup.
Recurring job-costing bookkeeping
Every transaction coded to its job. Labor, materials, subs, overhead. Change orders, retainage, AIA billing maintained. WIP updated monthly. All inside monthly bookkeeping.
Reporting & review
A monthly package with job-profitability, WIP, estimated-vs-actual, and segment views — the reports that turn into pricing and bidding decisions, not a binder nobody opens.
What we do, don’t, and who we coordinate with.
Operational accounting, drawn clearly — so the boundary with tax, audit, legal, and wage-rate work is never blurred.
We do
Job-costing setup in QuickBooks. Cost-code structure. Payroll and burden allocation. Materials, subs, and equipment tracking. Change orders, retainage, AIA-style progress billing (G702/G703). WIP schedules and over/under recognition. Monthly job-profitability and estimated-vs-actual reporting. Certified payroll bookkeeping, in coordination with payroll counsel where required.
We don’t
File income tax returns or represent before the IRS. Provide tax-position or legal advice. Issue formal audit, review, or compilation reports. Provide construction-law or surety-bond counsel. Set prevailing-wage rates or interpret labor law — we book the numbers; your counsel sets the rates.
We coordinate with
Your CPA or EA for tax. Your construction or labor counsel on prevailing-wage and certified-payroll rules. Your surety, banker, and bonding company on WIP and lender requirements. Your estimator and project managers on cost coding and change-order workflow.
Job-level numbers change how you bid — if anyone reads them.
Job-profitability reports surface patterns: which job types make money, which clients are worth more time, where estimates consistently miss, when scope creep is killing margin. Acting on those patterns — in bidding, pricing, staffing, and which work to chase — is where the discipline turns from accounting into strategy.
Most TechBrot clients pair job-costing bookkeeping with monthly performance review — the working session that turns job reports into decisions. For larger contractors and agencies, a fractional CFO takes job costing as one piece of a broader strategic-finance seat. As automation handles the routine, this interpretation layer is where the real value now lives. Explore advisory →
