Construction accounting & bookkeeping built for Seattle contractors
Most Seattle contractors don't lose money on the build. They lose it afterward: retainage that sits uncollected for months, job costs that never quite tie out, and books that aren't ready when the bank or bonding company asks. With some of the highest labor costs in the country and Washington's B&O tax taking a cut of gross receipts whether a job made money or not, the margin for sloppy books is thin. A regular bookkeeper isn't set up for construction. We keep the books for Seattle builders the way they should be kept: clean job costing, real WIP schedules, retainage tracked to the dollar, and numbers your bank and bonding company trust. We work with general contractors, concrete and site crews, mechanical trades, and commercial builders across the Seattle metro.
On the ground
Seattle construction accounting
Seattle is one of the fastest-growing construction markets in the nation with tech campus builds, a high-rise boom, transit expansion, and seismic retrofit mandates. Standard small-business bookkeeping cannot keep up with the complexity of managing multiple active projects in this market.
They didn’t just record transactions and call it a day. They built a custom chart of accounts around how a remodeling company actually runs, did a full catch-up on years of bookkeeping inside QuickBooks Online, and now stay on top of my monthly bookkeeping and payroll. Every step, they broke it down in simple terms instead of burying me in accountant talk.
FinTruction rebuilt the whole thing from the ground up, with real job costing, work in progress, and retainage. They didn’t just hand me reports and disappear; they walked me through my numbers until I understood them.
Sahil and his team handle the bookkeeping and job costing for my painting business. They cleaned up my books and set up integrations that give me accurate, timely job costing with solid weekly data. Reliable, detailed, and genuinely invested in getting the numbers right.
FinTruction is the only bookkeeping team we’ve found that truly understands construction accounting and WIP reporting. They aligned our income and costs across 21 jobs and gave us full, monthly transparency. Fast, accurate, and an indispensable partner.
When I came to FinTruction I had no financial structure. No job costing, no WIP tracking, books behind. They did a full cleanup and rebuilt job costing and WIP tracking in QuickBooks. Now I know what’s billed, what’s owed, and where every job stands.
A couple of minutes from a contractor we support, sharing what working with FinTruction has been like and what changed once their numbers finally made sense.
Seattle is one of the most dynamic construction markets in the United States. The city's skyline continues to transform with dozens of high-rise residential and commercial towers under construction at any given time. Tech industry expansion from Amazon, Meta, Google, and other major companies has fueled billions of dollars in campus construction, office development, and data center projects across the city and surrounding areas.
Sound Transit's multi-billion dollar light rail expansion is one of the largest public infrastructure projects in the Pacific Northwest. The program includes new stations, elevated guideways, tunneling, and transit-oriented development that creates sustained demand for contractors across multiple trades. The Seattle waterfront redevelopment following the Alaskan Way Viaduct removal represents another transformative infrastructure investment driving construction activity.
Seattle's housing crisis has intensified demand for multi-family residential construction, affordable housing projects, and mixed-use developments throughout the city. Mandatory Housing Affordability requirements and inclusionary zoning add layers of financial complexity to residential projects. Additionally, Seattle's unreinforced masonry building retrofit mandate is creating a steady pipeline of seismic retrofit work that requires specialized cost tracking.
FinTruction understands the financial demands of operating in Seattle's high-stakes construction market. Our construction accounting services are built to support contractors who manage large-scale projects, navigate dual B&O tax obligations, comply with prevailing wage requirements under RCW 39.12, and need financial reporting that satisfies banks, bonding companies, and CPAs.
We provide contractor bookkeeping services in Seattle designed specifically for construction businesses. Our team maintains clean, reconciled, CPA-ready financial records that account for Seattle's unique dual B&O tax structure and high-volume project environments.
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 Seattle can track every dollar by project. From Amazon campus builds and downtown high-rises to Sound Transit station construction and waterfront redevelopment, 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 Seattle. Whether you are bidding on Sound Transit expansion contracts or managing a portfolio of high-rise projects, accurate WIP schedules are essential for bonding capacity and financial credibility in Seattle's competitive market.
Retainage is one of the most mismanaged line items in construction accounting. Seattle contractors typically hold 5% retainage on contracts, and under RCW 60.28, public project retainage has specific release requirements. With the scale of projects in Seattle, retainage balances can be substantial. 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.
Seattle contractors face a unique dual-layer tax environment with both Washington State and City of Seattle B&O taxes on gross receipts, plus 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 this tax structure so you stay compliant and minimize your tax burden.
Growing construction companies in Seattle 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 Seattle's fast-paced, high-value construction market.
Our construction accounting services support a wide range of contractors and specialty trades operating across the Seattle metropolitan area. Whether you run a crew of five or manage a multi-million dollar tech campus project, we build financial systems that match the way your construction business works.

Seattle contractors face a dual B&O tax obligation. Washington State imposes a B&O tax on gross business receipts, and the City of Seattle levies its own B&O tax on businesses operating within city limits. Construction contractors must properly classify revenue under retailing or service categories for both state and city tax filings. FinTruction helps Seattle contractors accurately classify revenue streams, track gross receipts by project, and file both state and city B&O tax returns correctly.
Contractors working on public works projects in Seattle must pay prevailing wages as determined by the Department of Labor and Industries. Sound Transit projects, city infrastructure, and port construction all fall under prevailing wage requirements. Rates include base hourly rates, fringe benefits, and travel allowances that vary by trade and King County rates. Our accounting team tracks applicable rates, prepares certified payroll reports, and ensures your records meet L&I audit requirements.
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. Seattle contractors working on larger projects must also verify that all subcontractors are properly registered. Our accounting systems track licensing fees, bond premiums, insurance costs, and subcontractor verification as part of your project-level financial management.
Seattle falls within a high seismic risk zone and has enacted mandatory retrofit requirements for unreinforced masonry buildings. New construction must meet stringent earthquake resistance standards under the International Building Code as adopted by Washington and Seattle building codes. Seismic compliance adds engineering, materials, and labor costs that must be tracked as distinct cost categories within job costing systems.
Unlike general accounting firms, we specialize exclusively in construction accounting and contractor bookkeeping.
FinTruction provides construction accounting in Seattle that integrates directly with the systems contractors already use. We connect your construction management software, payroll systems, and accounting platforms to create real time financial visibility and accurate job costing.
We configure QuickBooks Online and QuickBooks Desktop specifically for construction companies in Seattle. From chart of accounts structure to job costing classes and progress invoicing, we set up your QuickBooks so it works the way contractors need it to.

FinTruction builds accounting systems that support decision making, not just compliance.
Seattle contractors operate in one of the most active construction markets in the country driven by tech campus expansion from Amazon and Meta, a high-rise building boom, Sound Transit light rail construction, waterfront redevelopment, and mandatory seismic retrofit projects. These project types demand specialized job costing, multi-phase budget tracking, and compliance with dual B&O tax obligations.
Washington's Business and Occupation tax is a gross receipts tax with no deductions for costs of doing business. Seattle contractors face a dual obligation because the City of Seattle also imposes its own B&O tax. Proper revenue classification under retailing or service categories is critical for both state and city filings to avoid penalties and overpayment.
Yes. Under RCW 39.12, contractors working on public works projects in Seattle must pay prevailing wages as determined by the Department of Labor and Industries. Sound Transit projects, city infrastructure work, and port construction all require certified payroll reports and wage rate compliance by trade and county.
Tech campus projects for companies like Amazon and Meta involve multi-phase construction with extended timelines, complex change order tracking, and large subcontractor networks. We set up job costing systems that track costs by phase and building, manage retainage across long project durations, and prepare WIP schedules that reflect the true financial position of these large-scale projects.
Seattle's unreinforced masonry building retrofit mandate requires building owners to upgrade structures to meet earthquake resistance standards. Contractors performing seismic retrofit work need separate cost tracking for engineering assessments, structural reinforcement materials, specialized labor, and compliance documentation. FinTruction captures these costs accurately within job costing systems.
Yes. Seattle's high-rise construction boom requires accounting for extended project timelines, complex AIA billing schedules, large retainage balances, multi-trade subcontractor management, and percentage of completion revenue recognition. We provide WIP reporting and job costing that meets the demands of high-rise general contractors and specialty subcontractors.
Seattle's housing shortage has driven rapid development of multi-family residential projects, affordable housing initiatives, and mixed-use developments. Contractors working on these projects deal with affordable housing tax credit compliance, inclusionary zoning cost tracking, and complex financing structures that require specialized accounting and reporting.
Yes. QuickBooks Online can be configured for construction accounting when set up correctly with proper chart of accounts, job costing classes, progress invoicing, and retainage tracking. FinTruction specializes in setting up QuickBooks for Seattle contractors managing complex project portfolios.
