What Is Job Costing and Why Should You Care?

- Materials and tools
- Travel and logistics
- Overhead allocations

Key Job Costing Features in QuickBooks Enterprise

Step-by-Step: Setting Up Job Costing in QuickBooks Enterprise
1. Set Up Customers and Jobs
- Create a customer profile
- Add sub-jobs (e.g., "Client A > Kitchen Remodel")
- Assign classes if you want to track job types or departments
2. Create Detailed Estimates
Use the "Estimate" form in QuickBooks to itemize expected:
- Labor hours and rates
- Materials and quantities
- Other direct expenses
This allows for Estimates vs. Actuals reporting later.
3. Track Expenses by Job
When entering bills, checks, or time entries, always assign the expense to a specific customer/job. This is how QuickBooks ties every cost to the correct job.
4. Use Timesheets or Time Tracking Tools
Record labor hours using:
- QuickBooks built-in timesheets
- 3rd-party apps like TSheets or ClockShark (integrates with QuickBooks)
This ensures payroll costs flow accurately into each job.
5. Run Job Costing Reports
Useful reports to monitor profitability:
- Job Profitability Summary
- Job Profitability Detail
- Unbilled Costs by Job
- Estimate vs. Actual Report
These help identify underperforming jobs and adjust course quickly.
Best Practices for Job Costing in a Service Business
Use Classes and Custom Fields Wisely
QuickBooks Enterprise allows tracking by class (e.g., department, service line) and custom fields. Use these to segment your reporting and analyze trends.
Schedule Monthly Job Reviews
Have monthly reviews of:
- Open jobs with pending invoices
- Completed jobs with unexpected losses
- Jobs with a high estimated variance
Keep Estimates Realistic
Involve field supervisors and project managers in your estimating process to ensure quotes reflect real-world costs.
Tracking Subcontractor Costs in QuickBooks Enterprise
Set Up Vendors as Contractors
For 1099 subcontractors:
- Set them up as vendors
- Enable 1099 tracking
- Assign all expenses and payments to jobs when recording bills or writing checks.
Use Purchase Orders for Subcontracted Work
Create POs for contractors and link them to jobs. This provides visibility into committed costs, even before the invoice arrives.
Advanced Tips for Power Users
Use Job Costing with Advanced Inventory
If your service business uses parts or materials:
- Use the Advanced Inventory module to track serialized items and assign inventory usage to jobs.
Integrate with Field Service Tools
Tools like ServiceTitan, Buildertrend, or Knowify integrate well with QuickBooks Enterprise for real-time job tracking and scheduling.
Leverage Custom Job Costing Dashboards
Using tools like Fathom, Qvinci, or Microsoft Power BI, you can create dashboards to track KPIs like:
- Gross margin by job
- Job completion timelines
- Cost overruns
When to Call in a QuickBooks ProAdvisor
If job costing feels overwhelming or if your reports aren't lining up, it may be time to consult a QuickBooks-certified ProAdvisor. They can:
- Customize your job costing setup
- Help migrate from spreadsheets or other software
- Train your team on best practices
