Construction bookkeeping services built for Seattle contractors
FinTruction provides construction bookkeeping in Seattle for general contractors, subcontractors, concrete companies, HVAC contractors, roofers, electricians, plumbers, and specialty trades operating across King County and the Puget Sound region. Our contractor bookkeeping services include daily transaction recording, bank reconciliations, accounts payable and receivable management, payroll tracking, retainage bookkeeping, and monthly financial statements tailored to the Seattle construction market.
Construction bookkeeping is not the same as bookkeeping for a retail store or a tech company. Seattle contractors deal with job-level cost tracking, retainage, progress billing, subcontractor payments, WA B&O tax obligations, and multi-project cash flow management. A general bookkeeper will not catch the financial issues that sink construction companies.
The foundation of accurate construction bookkeeping is recording every transaction to the right job, the right cost code, and the right account. We handle daily transaction entry so your books are always current and every dollar is tracked at the project level.
Seattle contractors manage dozens of vendor and subcontractor relationships across multiple projects in the Puget Sound region. We keep your accounts payable organized, ensure bills are coded to the correct jobs, and help you stay on top of payment schedules so you maintain strong vendor relationships and avoid late payment penalties.
Getting paid on time is the lifeblood of every construction company. We manage your accounts receivable, prepare progress billing submissions, track retainage held by clients, and follow up on outstanding invoices so your cash flow stays healthy.
Unreconciled books are unreliable books. We reconcile every bank account, credit card, and line of credit monthly so your financial statements are accurate and your CPA gets clean numbers at year-end.
Labor is the largest expense for most Seattle construction companies. We ensure payroll costs are allocated to the correct projects so your job costing reports reflect actual labor burden per job, not just company-wide averages.
Every month you will receive clean, accurate financial statements that show you exactly how your construction company is performing. These reports are formatted for construction and ready for your CPA, bank, or bonding company.
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 →
Our construction bookkeeping services support contractors and specialty trades of all sizes across the Puget Sound region. Whether you run a crew of five or manage a multi-million dollar operation, we keep your books clean and job-level accurate.
Are You a Contractor in Seattle?
Get Clean Books and Financial ClaritySeattle is one of the most active construction markets in the Pacific Northwest. The Puget Sound region is experiencing sustained growth driven by tech campus expansions from Amazon, Microsoft, and Meta, Sound Transit light rail development, seismic retrofit projects mandated by updated building codes, and a steady pipeline of commercial and residential high-rise construction.
With this volume of construction activity comes financial complexity. Seattle contractors manage dozens of active jobs, hundreds of vendor relationships, and thousands of transactions every month. Without construction-specific bookkeeping, expenses get miscoded, retainage balances go untracked, and cash flow problems develop before anyone notices.
Accurate bookkeeping is not just about compliance. It is the foundation that supports job costing, WIP reporting, bonding applications, tax planning, and every financial decision your construction company makes. When your books are wrong, everything built on top of them is wrong too.
FinTruction provides construction bookkeeping in Seattle that keeps your financial records clean, current, and coded to the job level. We understand the pace and scale of the Puget Sound construction market and build bookkeeping systems that keep up with it.
Washington B&O Tax Records: Washington levies a Business and Occupation tax on gross receipts rather than net income. Seattle construction companies must track all revenue by project accurately because B&O tax applies to total receipts regardless of profitability. Our bookkeeping maintains precise revenue records by job so your B&O tax filings are accurate and defensible during an audit.
Sales Tax on Construction Materials: Washington charges sales tax on construction materials at a combined state and local rate that can reach 10.4% in the Seattle area. The state base rate is 6.5% with local additions varying by jurisdiction. Our bookkeeping separates taxable material purchases from labor and subcontractor costs so your sales tax records are accurate and audit-ready.
WA Lien Law and Pre-Claim Notice: Washington requires subcontractors and material suppliers to serve a pre-claim notice to protect their lien rights, with a 90-day deadline to file a lien after the last date of furnishing labor or materials. Our bookkeeping tracks project dates, contract amounts, and all billings and payments by project so your lien rights documentation is always current and defensible.
1099 Reporting for Subcontractors: Contractors who pay subcontractors $600 or more annually must issue 1099-NEC forms. Our bookkeeping processes track every subcontractor payment by vendor and project throughout the year so 1099 preparation is accurate and on time.
Certified Payroll for Public Works Projects: Seattle contractors working on public works projects must comply with Washington prevailing wage requirements and submit certified payroll reports. Our bookkeeping tracks wage rates, hours by project, and fringe benefit payments so certified payroll reports can be prepared accurately and without last-minute scrambling.
Unlike general bookkeeping firms, we work exclusively with construction companies and understand the financial workflows that contractors depend on.
FinTruction provides construction bookkeeping in Seattle using the software your company already runs. We connect your accounting platform, construction management tools, and payroll systems so every transaction flows into your books accurately.
