Real-Time Job Costing for Electrical Contractors: Stop Finding Out You Lost Money After the Job

DEFINITION

Real-Time Job Costing

Tracking actual costs (labor, materials, equipment, subcontractor invoices) against budgeted costs continuously during a job, not after completion. The goal is to see margin erosion while there is still time to correct it: reassign crew, renegotiate material orders, or submit a change order.

DEFINITION

Cost-to-Complete

An estimate of remaining costs to finish a job, calculated from work completed so far plus projected remaining labor and materials. When combined with costs already incurred, this gives you the projected total cost and whether the job will meet, exceed, or fall short of the bid.

DEFINITION

Earned Value

The budgeted cost of work actually completed. If you bid $100K on a job and have completed 40% of the work, the earned value is $40K. Comparing earned value to actual costs tells you whether you are ahead or behind on margin at any point during the job.

The $3M-$8M Electrical Contractor’s Problem

At $3M-$8M in annual revenue, you are past the point where you can keep job costs in your head and below the point where a full-time controller makes financial sense. You are running 5-15 active jobs, managing 10-30 electricians, and your office manager handles AP, AR, payroll, and job costing in the same week.

The result is that job costing happens in arrears. You find out a job lost money 2-4 weeks after it is complete, when the final labor hours are tallied and the last material invoices come in. By then, there is nothing to do about it except learn the lesson and hope the next bid is better.

Real-time job costing flips this timeline. Instead of a post-mortem, you get a dashboard that shows cost-to-complete projections while work is in progress. If a rough-in is burning labor faster than budgeted, you see it this week, not next month.

What Real-Time Looks Like in Practice

Every Monday morning, you open MarginLock and see each active job’s status: budgeted vs. actual labor hours, material costs to date vs. budget, and a cost-to-complete projection. Jobs trending over budget are flagged. Jobs with submitted but unapproved change orders are highlighted so you know which margin recovery is pending.

Your foremen log time by cost code at the end of each day using the mobile app. Material invoices are entered by your office manager as they arrive. The system compares actuals to the bid breakdown continuously. When labor on a specific cost code exceeds 80% of budget with only 60% of the work complete, you get a notification.

This gives you time to act. Reassign a slower crew member. Send a change order for the scope creep the GC added verbally. Renegotiate a material delivery schedule. These are decisions that save margin, but only if you have the information while the job is still active.

The Spreadsheet Ceiling

Spreadsheet-based job costing works until it does not. The breaking point is usually 5-7 simultaneous active jobs. Below that, your office manager can maintain separate spreadsheets for each job and update them weekly. Above that, the data entry backlog grows, reconciliation takes longer, and the numbers are always stale by the time you review them.

The spreadsheet also cannot alert you proactively. You have to open each file, check the numbers, and mentally compare them to the bid. With 10 active jobs, that review takes hours and still depends on the data being current.

We built MarginLock because we saw electrical contractors hitting this ceiling repeatedly: too big for spreadsheets, too small for Foundation Software’s implementation cost and per-seat pricing. The flat-rate model means your cost does not increase when you add a foreman or a second office person to the system.

The Cost of Late Information

When you find out a job lost 5% margin after completion, the loss is locked in. When you find out the same job is trending 5% over budget at the 40% completion mark, you have options. That difference between post-mortem and real-time is the entire value proposition of job costing software.

For a $3M-$8M electrical contractor running 10 jobs per year, recovering even 2% margin per job through earlier intervention is $60K-$160K in annual profit. That dwarfs the cost of any job costing software on the market.
