Why Track Job Profitability?

Many trade businesses are busy but not profitable. Tracking each job helps you understand which work is worth doing.

Common Profit Killers

  • Scope creep - Extra work added without adjusting the price
  • Underestimating time - Jobs take longer than quoted
  • Material waste - Ordering too much or making mistakes
  • Multiple site visits - Travel time eating into profit
  • Hidden costs - Forgetting permits, parking, disposal fees

What to Do With This Data

  • Identify patterns - Which job types are most profitable?
  • Improve estimating - Learn how long jobs actually take
  • Adjust pricing - Increase quotes for consistently unprofitable work
  • Focus efforts - Do more of the work that pays well
  • Cut losses - Stop accepting unprofitable clients or job types

Target Profit Margins

Aim for 30-40% profit margin on small jobs and 20-30% on larger projects. Lower margins are acceptable on very large jobs with predictable costs.
