Job Costing Tips for Architects & Engineers: Improve Profitability on Every Project

Architectural and engineering (A&E) firms face some of the most complex project landscapes in business. Without accurate and effective job costing systems, even high-revenue projects can quietly turn into financial headaches. Gaining clear visibility into labor, overhead, and phase-by-phase performance is essential to keeping your projects on track and your margins healthy.

This month, we’re sharing job costing strategies tailored specifically for A&E professionals.


🏗️ Track by Phase, Not Just by Project

Design. Development. Permitting. Construction administration. Each phase of an A&E project has different time, complexity, and staffing demands.

▪️ Assign time and expenses by phase in your accounting software or project management system.

▪️ Compare estimated vs. actual costs per phase to spot scope creep early.

▪️ Use this insight to improve estimates or renegotiate change orders before they hurt your margin.


👥 Track by Role or Department

An engineer’s billable rate is very different from a junior drafter’s, and their impact on profit is, too.

▪️ Track labor hours by role or team to see where high-cost labor is over- or under-utilized.

▪️ Use this data to make smarter staffing decisions and build more accurate proposals.


🕒 Timesheets: Your Most Underrated Tool

Yes, everyone groans at the word. But accurate, detailed timesheets are your most powerful source of job costing data.

▪️ Require team members to log time daily, even if it’s rounded in 15-minute increments.

▪️ Track time by phase, task type, or client code for better analysis.

Don’t just mark time as non-billable, track why it wasn’t billable (internal revisions? client delays?).


💰 Include Soft Costs Like Software and Subscriptions

Tools like CAD, Adobe, or Asana might span multiple projects, but they’re still part of your cost base.

▪️ Allocate software and tech costs by headcount or time spent per job.

▪️ Evaluate ROI across projects and justify tech upgrades when the value is clear.


🔄 Schedule Regular Project Cost Reviews

Internal checkpoints help you course-correct before it’s too late.

▪️ Review job costing data at 25%, 50%, and 75% completion stages.

▪️ Flag early indicators of scope creep, budget overruns, or delays.

▪️ Adjust resources or priorities mid-project to protect your margins.
