Bookkeeping for Contractors & Trades Businesses

Contractors and trades businesses face unique financial challenges that standard bookkeeping services are not equipped to handle. At Pro Trade Bookkeeping, we specialize in bookkeeping for contractors, construction companies, and skilled trades, helping business owners understand their numbers, protect cash flow, and make confident decisions.

Whether you’re an electrician, plumber, HVAC company, roofer, or general contractor, your books need to do more than “balance”. They need to support job costing, cash flow planning, and long-term growth.

Why Bookkeeping for Contractors Is Different

Bookkeeping for contractors is fundamentally different from bookkeeping for service businesses, retail companies, or online brands.

Contractors Deal With:

  • Job-based income and expenses

  • Progress payments and deposits

  • Retainage and delayed cash collection

  • Labor-heavy payroll costs

  • Equipment purchases and depreciation

  • Multiple jobs running at the same time

A generic bookkeeper may keep your books “clean,” but without contractor-specific knowledge, your financial reports won’t tell you:

  • Which jobs are profitable

  • Where money is leaking

  • Why cash feels tight even when sales look strong

Job Costing: The Backbone of Contractor Bookkeeping

One of the biggest differences in bookkeeping for the trades is job costing.

What Is Job Costing?

Job costing tracks income and expenses by individual job or project, not just by month.

This allows contractors to:

  • See profit (or loss) on each job

  • Compare estimated vs actual costs

  • Identify underbidding issues

  • Improve future pricing

A profitable company on paper can still lose money job-by-job. And most contractors don’t realize it until it’s too late.
