Bookkeeping for Contractors and Trades Businesses

Contractors have unique bookkeeping needs: job costing, deposits, subcontractor payments, and material tracking. We set up QuickBooks to match how your projects actually run so you can see profitability per job and make better decisions.

Why Generic Bookkeeping Falls Short for Contractors

Most bookkeepers categorize transactions and reconcile accounts. That is important, but it is not enough for contractors. When you are running multiple jobs with different deposit schedules, subcontractor payments, material purchases, and progress billing, you need bookkeeping that tracks profitability at the job level. Without job costing, you know your overall revenue but have no idea which projects are making money and which are not. Plumb Financial specializes in bookkeeping for contractors, remodelers, and trades businesses across Snohomish County and the greater Seattle area.

Job Costing That Shows You the Real Numbers

We set up QuickBooks so every income and expense ties back to the right project. That means you get job-level profit and loss reporting that shows which jobs are making money, which ones are breaking even, and where your margins are getting squeezed.

For general contractors, remodelers, and specialty trades, this visibility is what separates businesses that grow steadily from those that stay stuck guessing. When you can see what each job actually cost, you can price the next one with more confidence.

Deposits, Progress Payments, and Subcontractor Tracking

Contractors deal with money that moves in unusual patterns: deposits that come in before work starts, progress payments tied to milestones, retention holdbacks, and subcontractor invoices that stack up. We handle the categorization and tracking so those transactions land in the right accounts and your cash picture stays accurate.

Subcontractor payments are tracked and organized for year-end 1099 preparation. Material purchases tie back to specific jobs. Your books stop being a mystery and start being a tool you can actually use.

Subcontractor and deposit tracking

This service is built for general contractors, remodeling companies, specialty trades (plumbing, electrical, HVAC, roofing), and other project-driven businesses in Washington state. If you manage crews, handle deposits, track materials, or work with subcontractors, your bookkeeping needs are different from a retail shop or a consultant. We understand that because our founder, Joe, comes from the trades and knows how these businesses operate from the inside. Monthly pricing typically falls between $800 and $1,500 depending on transaction volume and number of active jobs.

To Say

Marcus T.

Before Plumb Financial, I had no real idea where my money was going month to month. Joe got our books cleaned up and organized, and now I actually understand our numbers. It has made a real difference in how I run the business.

Sarah K.

We were growing fast but struggling with cash flow, and I didn't have a clear picture of what was happening. Working with Plumb Financial gave us the reporting we needed to make smarter decisions on pricing and hiring. I wish we had done this sooner.

David R.

What I appreciated most was that Joe actually understands how project-based businesses work. The bookkeeping is clean and current, and the CFO advisory side has been genuinely useful, not just a monthly check-in.

Rachel M.

Straight communication and no surprises. That's what I was looking for and that's exactly what I got. Our financials finally make sense, and I feel confident about where the business stands.
