Job-costed books and an on-time monthly close for Seattle contractors
Here is the trap most Seattle builders know too well. Washington's B&O tax takes a cut of your gross receipts whether a job made money or not, so the state gets paid off the top line while your margin gets squeezed underneath, and the only defense is books that record every dollar of revenue by job and tax classification. Then the market does what Seattle does: tech-campus and high-rise work lands faster than anyone can enter it, and the books end up a step behind the field. By month-end you are stuck guessing which job a charge belonged to and reconstructing revenue for the B&O return under deadline. A general bookkeeper treats a contractor like a retail shop and never separates the B&O classifications. We work only with construction companies, so for Seattle contractors we record your revenue by job and by B&O tax category as it lands, code each cost to the right project, manage AP and AR, track retainage, keep QuickBooks construction-ready, and close the month on a fixed date so your B&O return is accurate and month-end arrives on time. We work with general contractors, concrete and site crews, mechanical trades, seismic retrofit specialists, and commercial builders across the Puget Sound.
On the ground
Seattle construction bookkeeping
Seattle runs one of the busiest construction markets in the country, and that pace is exactly what buries a contractor's books. Tech-campus expansion from Amazon, Microsoft, and Meta, a downtown high-rise boom, Sound Transit light-rail construction, waterfront redevelopment, and mandatory seismic retrofits mean most builders are running several active projects at once.
Every one of those jobs generates a stream of transactions: subcontractor bills, material runs, equipment rentals, progress draws, retainage held and released, and prevailing-wage payroll that has to be split across projects. Multiply that by a full slate of active work, add gross receipts that must be recorded by B&O classification whether or not the job was profitable, and the bookkeeping backlog grows faster than any owner can keep up with between site visits.
When the books fall behind, the damage is quiet but real. Cash flow decisions get made on stale numbers, miscoded costs hide which jobs are actually losing money, the B&O return becomes a month-end reconstruction, and the year-end handoff to a CPA turns into an expensive cleanup. The work was profitable; the record-keeping is what put the company at risk.
FinTruction keeps Seattle contractors out of that hole. We match the pace of the market with a disciplined monthly process so your books stay clean, current, and coded to the job, and you always know where the money went.
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.
Accurate books start with putting every dollar against the right job, cost code, and account the day it happens. When Seattle work is moving fast, daily entry is the only thing that stops the books from drifting a month behind. We keep your QuickBooks current so you can see where each job actually stands instead of finding out at month-end.
If your file is a mess or you are months behind, we fix it. Many Puget Sound contractors come to us with miscoded expenses, undeposited funds sitting for months, B&O revenue never split by classification, and no real job costing. We rebuild the file for construction and bring every account current so you can trust the numbers again.
Seattle contractors run dozens of subcontractor and supplier relationships across every project. We keep AP organized, code each bill to the right job, and stay ahead of payment schedules so you protect vendor relationships, avoid late fees, and reach year-end with clean 1099 records.
Getting paid keeps the doors open, and on Seattle tech-campus, high-rise, and transit work that means multi-draw billing with 5% retainage held for months. We record every progress draw and AIA pay application accurately, track retainage receivable by project, and follow the aging so nothing slips.
Labor is the biggest line for most Seattle builders, and with some of the highest labor costs in the country it only tells the truth if it is coded to the right job. We record payroll, allocate labor to projects and cost codes, and keep the documentation Washington prevailing-wage work demands under RCW 39.12.
Every month you get a clean, construction-formatted statement package on a fixed date, reconciled and ready for your CPA, bank, or surety, with gross receipts already recorded for your B&O filing. No more waiting weeks to find out how the business did.
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.

Bookkeeping for a construction company in Seattle is nothing like bookkeeping for a shop or an office. Between B&O tax charged on gross receipts, retainage held for months, subcontractor payments across dozens of vendors, prevailing-wage payroll on public work, and revenue that has to be split by tax classification, a general bookkeeper simply codes it wrong. Accurate, job-level books are the foundation everything else stands on.
A general bookkeeper can record transactions. Construction accounting is a different job.

Are You a Contractor in Seattle?
Get Clean Books and Financial Clarity
Washington charges its Business and Occupation tax on gross receipts rather than net income, and the City of Seattle levies its own B&O tax on top. That makes clean revenue records non-negotiable. Our bookkeeping records total receipts by project and separates retailing from service classifications so both your state and city B&O filings come straight off the books instead of being rebuilt at deadline.
Washington has no state income tax, but that does not lighten the bookkeeping load. Contractors still face B&O tax on gross receipts, sales and use tax on materials and equipment, and federal filing. We keep revenue and expenses coded by project so every one of those obligations is supported without a scramble.
Washington applies sales tax on construction materials at a combined state and local rate that reaches roughly 10.4% in the Seattle area, with use tax owed on equipment and out-of-state purchases. We separate taxable material purchases from labor and subcontractor costs in your records so tax reporting is accurate and audit-ready.
Public works in Seattle, including Sound Transit, city infrastructure, and port projects, require prevailing wages and certified payroll under RCW 39.12. Our bookkeeping keeps wage rates, hours by project and trade, and fringe payments recorded so certified payroll and L&I filings can be produced without scrambling.
Washington requires subcontractors and suppliers to serve a pre-claim notice to protect lien rights, with a lien filed within 90 days of the last date labor or materials were furnished. Our bookkeeping tracks project start dates, last-furnishing dates, contract amounts, and all billings and payments by project so your lien documentation is always current.
We work only with construction companies, so we code your books the way contractors actually operate, not the way a general bookkeeper guesses.
FinTruction runs your construction bookkeeping in Seattle on the software you already use. We connect your accounting platform, field and project management tools, and payroll so transactions flow into clean books without double entry.
We set up and maintain QuickBooks Online and Desktop specifically for Seattle contractors, so job costing, retainage, B&O revenue classes, and progress invoicing are handled correctly from the first entry rather than bolted on later.
Need QuickBooks Cleaned Up for Construction?
We connect the tools your Seattle crews use in the field to your books so draws, costs, and payments flow through without manual re-entry.
Because Washington's Business and Occupation tax is charged on gross receipts, not profit, your books have to record total revenue by project and by tax classification whether the job made money or not. On the bookkeeping side that means every draw and deposit is coded so retailing and service receipts stay separated for both the state and City of Seattle filings. We keep those revenue records clean and current so your monthly B&O numbers come straight off the books instead of being rebuilt at deadline.
Yes, that is the core of what we do for busy Seattle contractors. When work is stacking up faster than the paperwork, transactions pile up uncoded and month-end turns into a guessing game. We take over daily coding and run a disciplined monthly close on a fixed date: bank and card reconciliations done, job costs coded, AP and AR current, and a statement package delivered the same day every month so the books stop trailing the field.
Yes. QuickBooks cleanup is one of the most common ways Puget Sound contractors start with us. We rebuild the chart of accounts for construction, fix miscoded costs and undeposited funds, set up job costing classes and items, correct retainage entries, split B&O revenue classifications properly, and reconcile back through the year. Once it is clean we keep it clean with a fixed monthly process.
Yes. We record every subcontractor payment against the right job and vendor throughout the year, collect W-9s up front, and flag anyone paid $600 or more so 1099-NEC filing is accurate and on time. On public work we also verify that subs are registered with Labor and Industries and keep that documentation attached to the project records.
Yes. Public works in Seattle fall under Washington prevailing wage rules in RCW 39.12, which require certified payroll. On the bookkeeping side we record wage rates, hours by project and trade, and fringe payments so certified payroll reports and L&I filings can be produced from your books without a last-minute reconstruction. We record the payroll and labor cost; strategy stays with your accountant.
Catch-up bookkeeping is a core service. We reconcile from the last clean month forward, recategorize transactions to the correct jobs and cost codes, sort out subcontractor and material payments, rebuild the B&O revenue records, and hand your CPA a clean set of books. Most Seattle contractors who are three to nine months behind are caught up within two to four weeks with no disruption to the field.
It depends on transaction volume, number of active jobs, payroll complexity, and whether you need catch-up work first. Most Seattle contractors find outsourced construction bookkeeping costs less than a full-time in-house bookkeeper while adding construction expertise they would not otherwise get. We give you a fixed monthly quote after a free consultation.
Bookkeeping is the day-to-day work: coding transactions to jobs, reconciling accounts, managing AP and AR, recording retainage and B&O revenue, and producing monthly statements. Accounting builds on those books with WIP reporting, revenue recognition, tax planning, and CFO-level analysis. Many Seattle contractors start with bookkeeping to get clean, current records, then add construction accounting in Seattle as they grow. We provide both.
