Construction accounting & bookkeeping built for Washington contractors
FinTruction provides construction accounting and bookkeeping in Washington for general contractors, subcontractors, concrete companies, HVAC contractors, roofers, electricians, plumbers, and remodeling firms. Our construction accounting and bookkeeping services include job costing, percentage of completion accounting, retainage tracking, AIA billing support, B&O tax compliance, prevailing wage tracking, and monthly contractor financial reporting.
Construction companies in Washington operate in a high-growth market with unique tax structures, prevailing wage mandates, and regulatory requirements. Traditional small-business bookkeeping is not enough for contractors who need accurate job costing, WIP reporting, and B&O tax compliance.
We provide contractor bookkeeping services in Washington designed specifically for construction businesses. Our team maintains clean, reconciled, CPA ready financial records that account for the unique tax and regulatory landscape of the state.
Every construction platform claims to have a "QuickBooks integration." Most break the moment your books need to be accurate. Sales tax mismaps, retainage disappears, change orders create duplicates, and job costing reports stop matching project reality. We fix the integration so your software, your books, and your job‑level numbers all tell the same story.
Also work with Foundation, Sage 100, Bill.com, ADP, Gusto, Ramp, and more. See all platforms we integrate →
We set up and manage job costing systems so contractors in Washington can track every dollar by project. From tech campus builds in the Puget Sound to infrastructure projects across Eastern Washington, our team ensures accurate cost allocation, budget monitoring, and margin analysis across all active jobs.
We prepare WIP schedules and manage revenue recognition for construction companies in Washington. Whether you are bidding on public projects or reporting to bonding companies, accurate WIP schedules are essential for financial credibility and growth.
Retainage is one of the most mismanaged line items in construction accounting. Washington contractors typically hold 5% retainage on contracts, and under RCW 60.28, public project retainage has specific release requirements. FinTruction manages retainage receivable and retainage payable at the project level so your balance sheet always reflects the true financial position of your construction company.
Washington contractors face a unique tax environment with no state income tax but a gross receipts B&O tax, retail sales tax on materials, and use tax on equipment. Our construction tax planning services align your job costing, WIP reporting, and revenue recognition with Washington's tax structure so you stay compliant and minimize your tax burden.
Growing construction companies in Washington need more than bookkeeping. Our controller services and CFO services give you executive-level financial oversight without the cost of a full-time hire. We provide strategic financial guidance tailored to the fast-paced Washington construction market.
Our construction accounting services support a wide range of contractors and specialty trades operating across Washington State. Whether you run a crew of five or manage a multi-million dollar operation, we build financial systems that match the way your construction business works.

Washington State is one of the most active construction markets in the Pacific Northwest and consistently ranks among the top states for total construction spending. The market is driven by tech industry expansion from companies like Amazon, Microsoft, Meta, and Boeing, along with major public infrastructure investments, residential development to address a housing shortage, and growing demand for green building and seismic retrofitting.
The Puget Sound region alone accounts for billions of dollars in annual construction permits. Projects range from high-rise commercial towers and tech campus developments in Seattle and Bellevue to Sound Transit light rail expansion, port infrastructure upgrades, and mixed-use residential projects. The region's growth has created sustained demand for contractors across all trades and project sizes.
Eastern Washington markets including Spokane and the Tri-Cities are experiencing their own construction booms driven by healthcare facility expansion, university campus construction, affordable housing development, and industrial warehouse projects. Statewide, Washington's commitment to green building standards and LEED certification adds another layer of complexity to construction project management and financial tracking.
FinTruction understands the financial demands of operating in this market. Our construction accounting services in Washington are built to support contractors who manage multiple active jobs, navigate the B&O tax structure, comply with prevailing wage requirements under RCW 39.12, and need financial reporting that satisfies banks, bonding companies, and CPAs.
Business and Occupation (B&O) Tax: Washington imposes a B&O tax on gross business receipts with no deductions for costs of doing business. Construction contractors are typically classified under the retailing B&O category for work that includes materials, or under the service category for labor-only contracts. Proper classification is critical because rates differ by category. FinTruction helps Washington contractors accurately classify revenue streams, track gross receipts by project, and file B&O tax returns correctly to avoid penalties and overpayment.
Prevailing Wage under RCW 39.12: Contractors working on public works projects in Washington must pay prevailing wages as determined by the Department of Labor and Industries (L&I). Wage rates include base hourly rates, fringe benefits, and travel allowances that vary by trade, county, and project type. Certified payroll reports must be submitted to the awarding agency. Our accounting team tracks applicable rates, prepares certified payroll reports, and ensures your records meet L&I audit requirements.
L&I Contractor Registration and Licensing: Washington requires all contractors to register with the Department of Labor and Industries. Registration includes maintaining a contractor bond, general liability insurance, and workers compensation coverage through either the state fund or a self-insured plan. Contractors must also verify that subcontractors are properly registered before engaging them on projects. Our accounting systems track licensing fees, bond premiums, insurance costs, and subcontractor verification as part of your project-level financial management.
Seismic Building Requirements: Washington falls within seismic zones that require buildings to meet specific structural standards for earthquake resistance under the International Building Code as adopted by Washington. Seismic retrofitting projects and new construction in higher-risk areas involve specialized engineering, materials, and labor that must be tracked as distinct cost categories. FinTruction helps contractors capture seismic compliance costs accurately within their job costing systems.
Green Building and Energy Code Compliance: Washington has some of the most aggressive energy codes in the nation, and many municipalities require or incentivize LEED certification and sustainable building practices. Green building projects often involve premium materials, specialized subcontractors, and additional inspections that increase project costs. Our accounting systems track green building cost premiums, energy rebate credits, and sustainability compliance expenses at the project level to give contractors accurate profitability reporting.

Washington's Business and Occupation tax is a gross receipts tax levied on all business income without deductions for costs or expenses. Construction contractors are classified under the retailing or wholesaling B&O category depending on the nature of the work. The tax applies to gross contract revenue, making accurate revenue tracking and classification essential for minimizing your tax burden.
No. Washington State does not impose a personal or corporate income tax. However, contractors are subject to the B&O tax on gross receipts, retail sales tax on materials, and use tax on equipment. Understanding these taxes and how they interact with federal tax obligations is critical for accurate construction accounting in Washington.
RCW 39.12 requires contractors and subcontractors on public works projects in Washington to pay prevailing wages as determined by the Department of Labor and Industries. Rates vary by trade, county, and project type. Contractors must submit certified payroll reports and maintain records of hours, wages, and benefits for each worker. FinTruction tracks prevailing wage rates and prepares compliant certified payroll documentation.
Yes. Washington requires all contractors to register with the Department of Labor and Industries and obtain a contractor license. Registration requires a surety bond, liability insurance, and workers compensation coverage. FinTruction ensures your accounting system tracks licensing fees, bond premiums, and insurance costs as part of your overhead allocation.
Washington's seismic zone classification requires buildings to meet specific structural standards for earthquake resistance. Seismic retrofitting and compliance add engineering, materials, and labor costs that must be tracked separately in job costing systems. FinTruction helps contractors capture these specialized costs accurately at the project level so you understand the true cost of seismic compliance on each job.
Washington has some of the most stringent energy codes in the nation. Many municipalities require or incentivize LEED certification and sustainable building practices.
