A Precision Accounting Consulting LLC Guide for General Contractors & Union Contractors
In today’s construction environment, margins are tight, competition is high, and costs are rising faster than ever. Yet more than 70% of contractors still do not perform proper job costing—meaning most have no clear idea what they actually earn on each project.
At Precision Accounting Consulting LLC, we see this every day. Contractors rely on total revenue, bank balances, or gut instinct to determine profitability. But without detailed job costing, you’re essentially flying blind—which often leads to missed profits, under-bidding, cash-flow issues, inaccurate WIP reports, and financing challenges.
The good news? When job costing is implemented correctly, the results are transformative.
What Is Job Costing? (And Why Most Contractors Don’t Do It)
Job costing is the process of tracking labor, materials, subcontractors, equipment, and overhead for each individual job so you can determine the true profitability of every project.
Contractors often skip job costing because:
- They believe they “know their numbers”
- They don’t have the internal accounting structure to support it
- Their software isn’t set up properly
- Labor isn’t being coded by job or phase
- No one internally has the bandwidth to maintain the system
But the cost of not doing it is far greater.
The Missing Piece: Contractors Lack the Internal Accounting Structure to Support Job Costing
This is one of the biggest reasons job costing fails—or never gets implemented correctly.
Job Costing Is Only as Good as the Data Behind It
If labor hours aren’t coded correctly…
If material invoices don’t hit the right job…
If subcontractor costs aren’t tracked properly…
If change orders aren’t added real time…
Your entire job costing system becomes unreliable.
Accurate job costing requires:
- A proper chart of accounts
- Well-defined cost codes
- Job-specific labor tracking
- Consistent invoice coding
- Weekly reconciliation
- Oversight from someone who knows construction accounting
Most Contractors Simply Don’t Have the Time or Staff for This
Your field and office teams are focused on running jobs and keeping operations moving. They don’t have hours every week to:
- Clean up timesheets
- Track fringe allocations
- Code materials accurately
- Follow up with suppliers
- Maintain real-time cost tracking
- Produce WIP reports
- Review job performance weekly
That’s why job costing often fails internally—not because contractors don’t want it, but because they lack the bandwidth and structure to support it.

Payroll-Side Job Costing: The Most Overlooked – and Most Critical – Component
Labor is one of the largest costs in any construction company, yet it’s often the least tracked. Payroll without job-level detail makes job costing impossible.
Precision Accounting Has Built Systems to Capture Job Costing Directly From Payroll
We work with specialized payroll vendors and platforms that allow us to:
- Track labor hours by job, phase, and cost code
- Allocate fringes and burden accurately
- Automate labor cost posting into accounting
- Integrate field time entry with accounting software
- Reduce manual entry and eliminate data errors
This ensures that labor—the biggest driver of cost—flows seamlessly into job costing.
Automated Certified Payroll Reporting
For union contractors and prevailing wage projects, certified payroll can be a major burden.
Our systems allow clients to:
- Automate certified payroll reports
- Reduce compliance risk
- Ensure accuracy of wage classifications
- Maintain proper fringe tracking
- Export reports for government agencies and unions
This saves hours of manual work and ensures your labor data is trustworthy.
When Payroll Data Is Captured Correctly, Job Costing Becomes Accurate and Powerful
Labor becomes the foundation of every job cost report. When payroll feeds job costing automatically:
- Overruns become visible sooner
- Productivity issues stand out
- Job profitability becomes accurate
- Your WIP schedule becomes reliable
This is one of the biggest reasons our clients see profit increases of 10–20% after adopting our full job costing systems.

- Reveals costly job types

Better WIP Reporting: No More Guesswork
WIP reports require accurate job costing. With the right data structure, you get:
- True percentage-of-completion reporting
- Proper revenue recognition
- Early visibility into job fade
- Trustworthy reporting for lenders and bonding companies
How Job Costing Strengthens Your Financing Position
Banks and bonding companies increasingly require. Job costing allows you to present:
- Detailed job profitability
- Accurate WIP schedules
- Strong financial statements
- Cost-to-complete schedules
- Predictable cash flow patterns
- Cash flow projections tied to projects
- Accurate cost-to-complete analysis
Contractors with real job costing get better rates, higher credit lines, and easier bonding approval.
Why Job Costing Is a Competitive Advantage (Especially for Union Contractors)
Union contractors must track labor, fringes, and classifications accurately. Job costing provides:
- True labor cost visibility
- Better compliance
- Improved bidding accuracy
- Control over crew productivity
Since most contractors still don’t do job costing correctly, adopting it gives you a massive strategic advantage.
